| 1 | Granular porous calcium carbonate particles for scalable and high-performance solar-driven thermochemical heat storage显示文摘Calcium carbonate is promising thermochemical heat storage material for next-generation solar power systems due to its high energy storage density,low cost,and high operation temperature.Researchers have tried to improve energy storage performances of calcium carbonate recently,but most researches focus on powders,which are not suitable for scalable applications.Here,novel granular porous calcium carbonate particles with very high solar absorptance,energy storage density,abrasive resistances,and energy storage rate are proposed for direct solar thermochemical heat storage.The average solar absorptance is improved by 234%compared with ordinary particles.Both cycle stability and abrasive resistances are excellent with almost no decay of energy storage density over 25 cycles nor apparent particle weight loss over 24 h of continuous operation insides a planetary ball mill.In addition,the decomposition temperature is reduced by 2.8%–5.6%while the reaction rate of heat storage is enhanced by 80%–205%depending on the CO_(2) partial pressure.The decomposition process of doped granular porous CaCO_(3) particles is found to involve three overlapping processes.This work provides new routes to achieve scalable direct solar thermochemical heat storage for next-generation high-temperature solar power systems. | SONG Chao LIU XiangLei XUAN YiMin ZHENG HangBin GAO Ke TENG Liang DA Yun LI Chuan LI YongLiang DING YuLong | 2021 | Science China(Technological Sciences)2021，64，10： | 4 |
| 2 | The influence of pore size distribution on thermal conductivity,permeability, and phase change behavior of hierarchical porous materials显示文摘Porous foams have been widely employed to improve heat storage rate and prevent leakage of phase change materials(PCMs).Actual porous foams have non-uniform or hierarchical pore size distribution, which is usually neglected in most researches.Here, we establish hierarchical porous models considering different pore size distributions by using Voronoi tessellations. Effects of pore size distribution on thermal conductivity, permeability, and phase change behavior of hierarchical porous foams/PCMs composites are investigated. Uneven pore size distributions are found to decrease the thermal conductivity of porous foams to some extent. On the other hand, the permeability can be reduced by 27.6%, and the heat storage rate can be improved by 7.7% by introducing moderate hierarchy without changing the total porosity. This work opens a new route to enhance heat storage performance of PCMs via leveraging hierarchy of pore size distribution of porous foams. | LIU XiangLei SONG FangZhou XU Qiao LUO QingYang TIAN Yang LI JiaWei YANG XinMeng JIN Yi | 2021 | Science China(Technological Sciences)2021，64，11： | 3 |
| 3 | An oncolytic adenovirus delivering TSLC1 inhibits Wnt signaling pathway and tumor growth in SMMC-7721 xenograft mice model显示文摘Tumor suppressor in lung cancer-1(TSLC1)was first identified as a tumor suppressor for lung cancer,and frequently downregulated in various types of cancers including hepatocellular carcinoma(HCC).The Wnt pathway plays a critical role in tumorigenesis,migration,and invasion in HCC.However,the function of TSLC1 in modulating Wnt signaling in HCC is unclear.In this study,we evaluated the effect of TSLC1-armed oncolytic adenovirus(S24-TSLC1)on the Wnt/β-catenin pathway,cell viability,invasion and migration abilities of HCC in vitro and the growth of SMMC-7721-xenografted tumor in mice model.We detected the expression of TSLC1 in tumor samples and HCC cell lines.The results showed that TSLC1 expression was low in HCC,but high in pericarcinomatous tissue and normal cells,which implied that TSLC1 is a tumor suppressor of liver cancer.S24-TSLC1 exhibited an antitumor effect on HCC cell growth in vitro,but did little damage to normal liver cells.Overexpression of TSLC1 downregulated the transcriptional activity of TCF4/β-catenin and inhibited the mRNA or protein expression of Wnt target genes cyclinD1 and c-myc.S24-TSLC1 also inhibited the invasion and migration of HCC cells.Animal experiments further confirmed that S24-TSLC1 significantly inhibited tumor growth of the SMMC-7721-xenografted tumor.In conclusion,TSLC1 could downregulate the Wnt signal pathway and suppress HCC cell growth,migration and invasion,suggesting that S24-TSLC1 may be a potent antitumor agent for future clinical trials in liver cancer treatment. | Yigang Wang Panpan Huang Yanping Hu Keni Guo Xiaoyuan Jia Biao Huang Xinyuan Liu Xianglei He Fang Huang | 2021 | Acta Biochimica et Biophysica Sinica2021，53，6： | 2 |

| 5 | From sawdust waste to high-value hierarchical ceramics-based phase change materials: Efficient dual functional thermal and solar energy storage显示文摘Latent heat thermal energy storage(LHTES) technology is gaining extensive attention due to its capability to balance supply and demand mismatch in solar energy utilization. However, phase change material as the core of storing latent heat still suffers from low thermal conductivity and poor shape stability, which severely restricts its practical application. Here, an eco-friendly strategy for achieving high-performance dual functional thermal and solar energy storage is proposed via turning wood processing waste into high-value hierarchical porous SiC ceramic-based composite phase change materials. The porosity of prepared porous SiC skeletons is highly adjustable from 59.4% to 90.2%, overcoming low porosity limitations of traditional wood materials and enabling tunable energy storage density for various applications. High thermal conductivity is achieved by benefiting from large grains and continuous skeletons with a value up to 37.93 and 1.87 W/(m K) for porosity of 59.4% and 90.2%, respectively.Excellent stabilities are demonstrated with only slight decreases of thermal conductivity and energy storage density over 1000 cycles and good anti-leakage properties are confirmed due to capillary adsorption forces induced by hierarchical pores. Benefiting from high thermal conductivity and high solar absorptance, fast and efficient solar thermal energy storage is successfully demonstrated. This work provides a new strategy for the high-value utilization of wood processing waste and efficient thermal/solar energy storage. | LIU XiangLei WEI PeiDong LUO QingYang XU Qiao WANG JianGuo LV ShuShan TIAN Yang YAO HaiChen XUAN YiMin | 2023 | Science China(Technological Sciences)2023，66，9： | 0 |
| 6 | Single-shot real-time compressed ultrahigh-speed imaging enabled by a snapshot-to-video autoencoder显示文摘Single-shot 2 D optical imaging of transient scenes is indispensable for numerous areas of study.Among existing techniques,compressed optical-streaking ultrahigh-speed photography(COSUP)uses a cost-efficient design to endow ultrahigh frame rates with off-the-shelf CCD and CMOS cameras.Thus far,COSUP’s application scope is limited by the long processing time and unstable image quality in existing analytical-modeling-based video reconstruction.To overcome these problems,we have developed a snapshot-to-video autoencoder(S2 V-AE)—which is a deep neural network that maps a compressively recorded 2 D image to a movie.The S2 V-AE preserves spatiotemporal coherence in reconstructed videos and presents a flexible structure to tolerate changes in input data.Implemented in compressed ultrahigh-speed imaging,the S2 V-AE enables the development of single-shot machine-learning assisted real-time(SMART)COSUP,which features a reconstruction time of 60 ms and a large sequence depth of 100 frames.SMART-COSUP is applied to wide-field multiple-particle tracking at 20,000 frames per second.As a universal computational framework,the S2 V-AE is readily adaptable to other modalities in high-dimensional compressed sensing.SMART-COSUP is also expected to find wide applications in applied and fundamental sciences. | XIANGLEI LIU JOÃO MONTEIRO ISABELA ALBUQUERQUE YINGMING LAI CHENG JIANG SHIAN ZHANG TIAGO H.FALK JINYANG LIANG | 2021 | Photonics Research2021，9，12： | 0 |
| 7 | Single-shot compressed optical field topography显示文摘Femtosecond lasers are powerful in studying matter's ultrafast dynamics within femtosecond to attosecond time scales.Drawing a three-dimensional(3D)topological map of the optical field of a femtosecond laser pulse including its spatiotemporal amplitude and phase distributions,allows one to predict and understand the underlying physics of light interaction with matter,whose spatially resolved transient dielectric function experiences ultrafast evolution.However,such a task is technically challenging for two reasons:first,one has to capture in single-shot and squeeze the 3D information of an optical field profile into a two-dimensional(2D)detector;second,typical detectors are only sensitive to intensity or amplitude information rather than phase.Here we have demonstrated compressed optical field topography(COFT)drawing a 3D map for an ultrafast optical field in single-shot,by combining the coded aperture snapshot spectral imaging(CASSI)technique with a global 3D phase retrieval procedure.COFT can,in single-shot,fully characterize the spatiotemporal coupling of a femtosecond laser pulse,and live stream the light-speed propagation of an air plasma ionization front,unveiling its potential applications in ultrafast sciences. | HAOCHENG TANG TING MEN XIANGLEI LIU YAODAN HU JINGQIN SU YANLEI ZUO PING LI JINYANG LIANG MICHAEL C.DOWNER ZHENGYAN LI | 2022 | Light(Science & Applications)2022，11，9： | 0 |
| 8 | Application of eDNA Metabarcoding for Detecting Anura in North China显示文摘eDNA metabarcoding is an advanced method formonitoring biodiversityproposed in recent years.By analyzing DNA in water,soil and sediment samples,the technology obtains species distribution and population quantity information.It was found that macrobarcode technology is more accurate than the traditional method in measuring the species richness of some groups.In Europe,America and South America,the relia bility of this technology in monitoring amphibian diversity in the wild was studied,and it was found to be better than traditional biodiversity monitoring methods in detecting species diversity.At present,amphibian monitoring mainly depends on various traditional methods,such as transects,drift fence traps,artificial shelters and mark-recapture.These monitoring techniques have many shortcomings,such as low accuracy and strong subjectivity of study results.These technologies have poor effects on rare,invasive and endangered species with strong concealment ability,low density and strong seasonality and are difficult to implement in sites inaccessible to people.Traditional monitoring technology also requires considerable investment of human and material resources,and the economic cost is relatively high,while eDNA metabarcoding ismore efficient and less costly,so it is important to use eDNA meta barcoding in amphibian monitoring in China.In this study,the eDNA meta barcoding and traditional line transect method(TLTM)were used to study the characteristics of the two methods in the Beijing-Tianjin-Hebeiregion.Repeated samplingwas conducted on 58 waterbodies in July 2019 and June 2020.After sequencing the samples using highthroughput sequencing technology,the differences between metabarcoding and commonly used TLTM surveys in detecting the diversity of four amphibians in North China were assessed.Our results showed that eDNA meta barcoding is more sensitive to the detection of the four amphibian species in the sampling area,and the combined use of eDNA metabarcoding and TLTM can improve the survey results of amphibians in the survey area to the greatest extent.In addition,in the process of species classification and identification of metabarcoding results,7 species of reptiles were detected,indicating that eDNA metabarcoding is also useful to detect reptiles.The results of this study indicate that metabarcoding in combination with TLTM can accurately estimate the diversityof amphibians in a short-term survey in North China and is also useful in reptile species detection. | Wenhao LI Mingshuo QIN Xianglei HOU Jiaqi ZHANG Siqi WANG Yu LI Zexu LUO Teng DENG Tianjian SONG Chunxia XU Xuan LIU Xuyu WANG Yiming LI | 2022 | Asian Herpetological Research2022，13，4： | 0 |
| 9 | Artificial“honeycomb-honey”decorated with non-noble plasmonic nanoparticles for superior solar capture and thermal energy storage显示文摘Phase change materials(PCMs)are popular solutions to tackle the unbalance of thermal energy supply and demand,but suffer from low thermal conductivity and leakage problems.Inspired by how honeybees store honey,we propose artificial“honeycombhoney”for excellent solar and thermal energy storage capacity based on TiN nanoparticles decorated porous AlN skeletonsPCMs composites.The thermal conductivity of composites achieves 21.58 W/(m·K)at AlN loading of 20 vol.%,superior to the state-of-the-art ceramic-based composites.The charging/discharging time is reduced to about half of pure PCMs with shapestability and thermal reliability well maintained over 500 melting/freezing cycles.The underlying mechanism can be attributed to the combination of single-crystal AlN whiskers with few crystal defects and reduced phonon scattering,as well as vertically arranged three-dimantional(3D)heat conduction channels.A rapid and efficient solar thermal storage is also demonstrated with solar thermal storage efficiency achieving a high value of 92.9%without employing additional spectrum selective coatings.This is benefited from high thermal conductivity and full-spectrum solar absorptance of up to 95%induced by plasmonic resonances of TiN nanoparticles.In addition,by embedding LiNO3-NaCl eutectics,the phase change enthalpy of composites reaches as high as 208 kJ/kg,making high energy storage density and fast energy storage rate compatible.This work offers new routes to achieve rapid,efficient,stable,and compact solar capture and thermal energy storage. | Haolei Wang Xianglei Liu Qingyang Luo Haichen Yao Qiao Xu Yang Tian Jianguo Wang Yimin Xuan | 2022 | Nano Research2022，15，9： | 0 |
| 10 | Air to fuel:Direct capture of CO_(2)from air and in-situ solar-driven conversion into syngas via Ni_(x)/NaA nanomaterials显示文摘Ever-increasing CO_(2)emissions and atmospheric concentration mainly due to the burning of traditional fossil fuels have caused severe global warming and climate change problems.Inspired by nature’s carbon cycle,we propose a novel dual functional catalyst-sorbent to tackle energy and environmental problems simultaneously via direct capture of CO_(2)from air and in-situ solar-driven conversion into clean fuels.Economically and operationally advantageous,the planned coupling reaction can be carried out in a single reactor without the requirement for an extra trapping device.The great CO_(2)capture and conversion performance in an integrated step is shown by the CO_(2)capacity of up to 0.38 mmol·g^(−1)for adsorption from 500 ppm CO_(2)at 25℃and the CO_(2)conversion rate of up to 95%.Importantly,the catalyst-sorbent is constituted of a nonprecious metal Ni catalyst and an inexpensive commercially available CO_(2)sorbent,viz,zeolite NaA.Furthermore,this designed dual functional material also exhibits outstanding stability performance.This work offers a novel pathway of capturing CO_(2)in the air at room temperature and converting it by CH4 into fuel,contributing to the new era of carbon neutrality. | Cheng Tian Xianglei Liu Chenxi Liu Shaoyang Li Qiyan Li Nan Sun Ke Gao Zhixing Jiang Kun Chang Yimin Xuan | 2023 | Nano Research2023，16，8： | 0 |
| 11 | Low glucose metabolite 3-phosphoglycerate switches PHGDH from serine synthesis to p53 activation to control cell fate显示文摘Glycolytic intermediary metabolites such as fructose-1,6-bisphosphate can serve as signals,controlling metabolic states beyond energy metabolism.However,whether glycolytic metabolites also play a role in controlling cell fate remains unexplored.Here,we find that low levels of glycolytic metabolite 3-phosphoglycerate(3-PGA)can switch phosphoglycerate dehydrogenase(PHGDH)from cataplerosis serine synthesis to pro-apoptotic activation of p53.PHGDH is a p53-binding protein,and when unoccupied by 3-PGA interacts with the scaffold protein AXIN in complex with the kinase HIPK2,both of which are also p53-binding proteins.This leads to the formation of a multivalent p53-binding complex that allows HIPK2 to specifically phosphorylate p53-Ser46 and thereby promote apoptosis.Furthermore,we show that PHGDH mutants(R135W and V261M)that are constitutively bound to 3-PGA abolish p53 activation even under low glucose conditions,while the mutants(T57A and T78A)unable to bind 3-PGA cause constitutive p53 activation and apoptosis in hepatocellular carcinoma(HCC)cells,even in the presence of high glucose.In vivo,PHGDH-T57A induces apoptosis and inhibits the growth of diethylnitrosamine-induced mouse HCC,whereas PHGDH-R135W prevents apoptosis and promotes HCC growth,and knockout of Trp53 abolishes these effects above.Importantly,caloric restriction that lowers whole-body glucose levels can impede HCC growth dependent on PHGDH.Together,these results unveil a mechanism by which glucose availability autonomously controls p53 activity,providing a new paradigm of cell fate control by metabolic substrate availability. | Yu-Qing Wu Chen-Song Zhang Jinye Xiong Dong-Qi Cai Chen-Zhe Wang Yu Wang Yan-Hui Liu Yu Wang Yiming Li Jian Wu Jianfeng Wu Bin Lan Xuefeng Wang Siwei Chen Xianglei Cao Xiaoyan Wei Hui-Hui Hu Huiling Guo Yaxin Yu Abdul Ghafoor Changchuan Xie Yaying Wu Zheni Xu Cixiong Zhang Mingxia Zhu Xi Huang Xiufeng Sun Shu-Yong Lin Hai-Long Piao Jianyin Zhou Sheng-Cai Lin | 2023 | Cell Research2023，33，11： | 0 |
| 12 | Super-Planckian thermal radiation enabled by hyperbolic surface phonon polaritons显示文摘Excitation of surface resonance modes and presence of resonance-free hyperbolic modes are two common ways to enhance the near-field radiative energy transport, which can find wide applications in noncontact thermal management and energy harvesting.Here, we identify another way to achieve the super-Planckian thermal radiation via hyperbolic surface phonon polaritons(HSPhPs). Based on the fluctuation-dissipation theory, the near-field radiative heat flux between bulk hexagonal boron nitride(hBN) planes with the optical axis perpendicular to the radiative energy flow can be 120 times as large as the blackbody limit for a gap distance of 20 nm. When the film thickness is reduced to 10 nm, the radiative heat flux is found to increase by 26.3%.The underlying mechanism is attributed to the coupling of Type I HSPhPs inside the anisotropic hBN film, which improves the energy transmission coefficient over a broad wavevector space especially for waves with extremely high wavevectors. This work helps to deepen the understanding of near-field radiation between natural hyperbolic materials, and opens a new route to enhance the near-field thermal radiation. | LIU XiangLei XUAN YiMin | 2016 | Science China(Technological Sciences)2016，59，11： | 0 |

| 14 | Current dilemma in photocatalytic CO_(2) reduction:real solar fuel production or false positive outcomings?显示文摘Solar driven carbon dioxide(CO_(2))recycling into hydrocarbon fuels using semiconductor photocatalysts offers an ideal energy conversion pathway to solve both the energy crisis and environmental degradation problems.However,the ubiquitous presence of carbonaceous contaminants in photocatalytic CO_(2) reduction system and the inferior yields of hydrocarbon fuels raise serious concerns about the reliability of the reported experimental results.Here in this perspective,we focus on the accurate assessment of the CO_(2) reduction products,systemically discuss the possible sources of errors in the product quantification,elaborate the common mistakes spread in the analysis of reaction products obtained in 13CO_(2) labelling experiments,and further propose reliable protocols for reporting the results of these isotopic tracing experiments.Moreover,the challenges and cautions in the precise measurement of O_(2) evolution rate are also depicted,and the amplification of the concentration of O_(2) in photoreactors well above the limit of detection is still demonstrated to be the most effective solution to this troublesome issue.We hope the viewpoints raised in this paper will help to assessment the reliability of the reported data in future,and also benefit the beginners that intend to dive in the photocatalytic CO_(2) reduction area. | Kai Zhang Qi Gao Cuiping Xu Dawei Zhao Qibin Zhu Zhonghui Zhu Jin Wang Cong Liu Haitao Yu Chen Sun Xianglei Liu Yimin Xuan | 2022 | Carbon Neutrality2022，1，1： | 0 |
| 15 | Efficient solar-driven CO_(2)-to-fuel conversion via Ni/MgAlO_(x)@SiO_(2)nanocomposites at low temperature显示文摘Solar-driven CO_(2)-to-fuel conversion assisted by another major greenhouse gas CH_(4)is promising to concurrently tackle energy shortage and global warming problems.However,current techniques still suffer from drawbacks of low efficiency,poor stability,and low selectivity.Here,a novel nanocomposite composed of interconnected Ni/MgAlOx nanoflakes grown on SiO_(2)particles with excellent spatial confinement of active sites is proposed for direct solar-driven CO_(2)-to-fuel conversion.An ultrahigh light-to-fuel efficiency up to 35.7%,high production rates of H_(2)(136.6 mmol min^(-1)g^(-1))and CO(148.2 mmol min^(-1)g^(-1)),excellent selectivity(H_(2)/CO ratio of 0.92),and good stability are reported simultaneously.These outstanding performances are attributed to strong metal-support interactions,improved CO_(2)absorption and activation,and decreased apparent activation energy under direct light illumination.MgAlO_(x)@SiO_(2)support helps to lower the activation energy of CH^(*) oxidation to CHO^(*) and improve the dissociation of CH_(4)to CH_(3)^(*) as confirmed by DFT calculations.Moreover,the lattice oxygen of MgAlO_(x) participates in the reaction and contributes to the removal of carbon deposition.This work provides promising routes for the conversion of greenhouse gasses into industrially valuable syngas with high efficiency,high selectivity,and benign sustainability. | Xianglei Liu Yueyue Ling Chen Sun Hang Shi Hangbin Zheng Chao Song Ke Gao Chunzhuo Dang Nan Sun Yimin Xuan Yulong Ding | 2024 | Fundamental Research2024，4，1： | 0 |
