| 1 | Physiological and subjective thermal responses to heat exposure in northern and southern Chinese people显示文摘When studying the thermal adaptation of building occupants,understanding the effects of different thermal experiences on adaptation is necessary,particularly for moderate and severe heat exposure.However,this area has seen limited research.Further,skin temperature,a common parameter for quantifying thermal sensation,may insufficiently reflect the automatic thermoregulation of the human body.This study investigates the effects of long-term heat exposure on the human body using multiple physiological and subjective indexes.Two heat exposure experiments were conducted on healthy male participants from northern and southern China.Participant responses,including skin temperature,heart rate,heart rate variability,blood volume pulse(BVP),subjective thermal comfort thermal sensation,thermal acceptability,and normalized high and low frequency values were collected and compared The results indicated that the subjective responses of northern and southern participants were not significantly different;however,the subjective physiological symptoms and self-reported discomfort of the latter were less than those of the former,indicating that the southern participants had superior heat tolerance.Additionally,the physiological responses of all the participants were largely similar.However,southern participants showed slightly higher normalized high frequency and BVP values,indicating that they have more active vagus nerves and better vasodilation.They also showed a wider acceptable temperature range and better acclimation to heat exposure.Notably,the mean skin temperature could not effectively predict thermal sensation during heat exposure;this was more accurately achieved using the rate of change of skin temperature.These findings suggest that long-term thermal experiences can affect building occupants’thermal adaptability. | Yufan Lin Liu Yang Maohui Luo | 2021 | Building Simulation2021，14，6： | 5 |
| 2 | Genesis of the Maoping carbonate-hosted Pb–Zn deposit,northeastern Yunnan Province,China:evidences from geology and C–O–S–Pb isotopes显示文摘The Maoping Pb-Zn deposit(~3 Mt Pb+Zn reserves with grades of 12-30 wt%)is one of the largest Pb-Zn deposits in the Sichuan-Yunnan-Guizhou(SYG)metallogenic province,which has contributed a tremendous amount of lead and zinc resources for China.To obtain a further understanding of the sources of ore-forming materials and ore genesis of the deposit,S-Pb isotopes of sulfides and C-O isotopes of ore-stage calcites were systematically collected from representative orebodies at different elevations with a Finnigan MAT-253 mass spectrometer.The calcites separated from the sulfides of the NoⅠand NoⅡorebodies shared identical b13 CPDB values(-5.3 to-0.8‰)andδ18OSMOW values(+14.5 to+21.8‰)with those of the calcites in the SYG region,suggesting that CO2 in regional ore-forming fluids possibly had a homologous C-O source that originated from a ternary mixture of the dissolution of marine carbonate rocks,degassing process of the Emeishan mantle plume,and dehydroxylation of sedimentary organic matter.The No.Ⅰ-1 and No.Ⅰ-2 orebody was hosted in the same strata,but the sulfur source of No.Ⅰ-1 orebody(+13.1 to+19.0‰)with equilibrated sulfur fractionation(δ34Sspbaierite-<δ34Sgalena)and No.Ⅰ-2 orebody(+18.0 to+21.8‰)with sulfur equilibrium fractionation(δ34Sspnaierite>δ34-Sgalena)were different.They were derived from the allopatry thermochemical sulfate reduction(TSR)of overlying Carboniferous sulfates in the ore-hosting strata and local TSR of sulfates in the ore-bearing Upper Devonian Zaige Formation,respectively.The narrow and uniform Pb isotopic ratios of single galena grains collected from sulfides with 206Pb/204Pb of 18.713-18.759,207Pb/204Pb of 15.772-15.776 and 208Pb/204Pb of39.383-39.467 indicate a well-mixed metal source(s)that consist of Proterozoic Kunyang and Huili Group basement rocks and Devonian to Middle Permian ore-hosting sedimentary rocks.Besides,the late Permian Emeishan basalts are difficult to contribute metals for regional Pb-Zn mineralization despite a closely spatial relationship with the distribution of the Pb-Zn deposit.This is supported by Pb isotopic ratios plotting above the average upper crustal Pb evolution curves and staying far away from that of the agecorrected Emeishan basalts.Hence,taking into account of the similarities in tectonic setting,ore-hosting rock,ore assemblage,wall rock alteration,ore-controlling structure,and ore-forming materials and the differences in relationship with regional magmatism,fluid inclusion characteristic and ore grade between the Maoping deposit and typical MVT Pb-Zn deposit,the ore genesis of the Maoping deposit should be an MVT like Pb-Zn deposit. | Yufan He Tao Wu Zhilong Huang Lin Ye Ping Deng Zhenzhong Xiang | 2020 | Acta Geochimica2020，39，5： | 3 |

| 5 | The anomalous Hall effect in epitaxial Fe(110) films grown on Ga As(110)显示文摘The anomalous Hall effect in epitaxial Fe(110)films grown on Ga As(110) is investigated as a function of both film thickness and temperature. The Berry curvatureinduced intrinsic contribution of 996 X 1cm 1is determined experimentally for the first time. Together with 821 X 1cm 1in Fe(111) and 1100 X 1cm 1in Fe(001)obtained earlier, we show unambiguously the anisotropy of the Berry curvature contribution to the anomalous Hall effect in single-crystal Fe. | Jianli Xu Lin Wu Yufan Li Dai Tian Kai Zhu Xinxin Gong Xiaofeng Jin | 2015 | Science Bulletin2015，60，14： | 1 |
| 6 | Impairment of rigidity sensing caused by mutant TP53 gain of function in osteosarcoma显示文摘Osteosarcoma(OS)is the most common primary malignant pediatric bone tumor and is characterized by high heterogeneity.Studies have revealed a wide range of phenotypic differences among OS cell lines in terms of their in vivo tumorigenicity and in vitro colony-forming abilities.However,the underlying molecular mechanism of these discrepancies remains unclear.The potential role of mechanotransduction in tumorigenicity is of particular interest.To this end,we tested the tumorigenicity and anoikis resistance of OS cell lines both in vitro and in vivo.We utilized a sphere culture model,a soft agar assay,and soft and rigid hydrogel surface culture models to investigate the function of rigidity sensing in the tumorigenicity of OS cells.Additionally,we quantified the expression of sensor proteins,including four kinases and seven cytoskeletal proteins,in OS cell lines.The upstream core transcription factors of rigidity-sensing proteins were further investigated.We detected anoikis resistance in transformed OS cells.The mechanosensing function of transformed OS cells was also impaired,with general downregulation of rigidity-sensing components.We identified toggling between normal and transformed growth based on the expression pattern of rigidity-sensing proteins in OS cells.We further uncovered a novel TP53 mutation(R156P)in transformed OS cells,which acquired gain of function to inhibit rigidity sensing,thus sustaining transformed growth.Our findings suggest a fundamental role of rigidity-sensing components in OS tumorigenicity as mechanotransduction elements through which cells can sense their physical microenvironment.In addition,the gain of function of mutant TP53 appears to serve as an executor for such malignant programs. | Ming Luo Mingyang Huang Ningning Yang Yufan Zhu Peng Huang Zhujun Xu Wengang Wang Lin Cai | 2023 | Bone Research2023，11，2： | 0 |
| 7 | Laser powder bed fusion of Zr-modified Al-Cu-Mg alloy:Processability and elevated-temperature mechanical properties显示文摘Zr modification is an effective method for improving hot-cracking resistance and elevated-temperature mechanical properties during laser powder bed fusion(L-PBF)of traditional medium and high strength wrought aluminum alloys.This study investigated the l-PBF processability and elevated-temperature mechanical properties of a Zr-modified 2024Al alloy.It was found that the hot-cracking susceptibility increased with the increased scanning speed,which was in reasonable agreement with the modified Rappaz-Drezet-Gremaud criterion.Furthermore,the primary L1_(2)-Al_(3)Zr precipitates,which acted as ef-ficient nucleation sites,precipitated at the fusion boundary of the melt pool,leading to the formation of a heterogeneous grain structure.The yield strength(YS)of the as-fabricated samples at 150,250,and 350℃was 363,210,and 48 MPa,respectively.Despite the slight decrease to 360 MPa of the YS when tested at 150℃,owing to the additional precipitate strengthening from the L1_(2)-Al_(3)Zr precipitates,the YS achieved yield strengths of 253 and 69 MPa,an increase of 20.5%and 30.4%,when tested at 250 and 350℃,respectively.The yield strengths in both the as-fabricated and T6-treated conditions tested at 150 and 250℃were comparable to those of casting Al-Cu-Mg-Ag alloys and superior to those of traditionally heat-resistant 2219-T6 and 2618-T6 of Al-Cu alloys. | Yanfang Wang Xin Lin Yufan Zhao Zihong Wang Xiaobin Yu Xuehao Gao Weidong Huang | 2023 | Journal of Materials Science & Technology2023，，5： | 0 |
| 8 | In-situ sugar-templated porous elastomer sensor with high sensitivity for wearables显示文摘Fabrication of elastic pressure sensors with low cost,high sensitivity,and mechanical durability is important for wearables,electronic skins and soft robotics.Here,we develop high-sensitivity porous elastomeric sensors for piezoresistive and capacitive pressure detection.Specifically,a porous polydimethylsiloxane(PDMS)sponge embedded with conductive fillers of carbon nanotubes(CNTs)or reduced graphene oxide(rGO)was fabricated by an in-situ sugar template strategy.The sensor demonstrates sensitive deformation to applied pressure,exhibiting large and fast response in resistance or capacitance for detection of a wide range of pressure(0‒5 kPa).PDMS,as a high-elasticity framework,enables creation of sensors with high sensitivity,excellent stability,and durability for long-term usage.The highest sensitivities of 22.1 and 68.3 kPa−1 can be attained by devices with 5%CNTs and 4%rGO,respectively.The geometrics of the sponge sensor is tailorable using tableting technology for different applications.The sensors demonstrate finger motion detection and heart-rate monitoring in real-time,as well as a capacitive sensor array for identification of pressure and shape of placed objects,exhibiting good potential for wearables and human-machine interactions. | Meng REN Ying FANG Yufan ZHANG Heli DENG Desuo ZHANG Hong LIN Yuyue CHEN Jiaqing XIONG | 2022 | Frontiers of Materials Science2022，16，2： | 0 |
| 9 | Evaluation of airborne transmission risk in university towns based on IEQ surveys显示文摘This study aims to evaluate airborne transmission risk in university towns during the COVID-19 pandemic based on surveys of indoor environmental quality(IEQ).Both on-site measurements and questionnaire surveys were carried out in public buildings in university towns in Changsha,China.Air temperature,relative humidity,and CO 2 concentration in one library,ten classrooms,eight canteens,seven restaurants,and sixteen malls were mea-sured.2220 valid questionnaires concerning occupants’sensation on thermal environment,air movement,and indoor air quality were collected.A 3-level evaluation method of airborne transmission risk that is dependent on building type and indoor CO 2 concentration was developed.Excessive CO 2 concentration is found in library(1045 ppm),classrooms(1151 ppm),restaurants(1242 ppm),and malls(1057 ppm).The percentage time of“high risk”accounts for 18-100%in these buildings.The results reveal a serious problem:numerous public buildings in China and probably other resource limited countries are not basically prepared and equipped to cope with airborne transmission.This fact should be taken into account when developing guidelines and formu-lating mitigation measures.Real-time monitoring and displaying IEQ and thus the transmission risk level should be an important way to be widely implemented in public buildings. | Yufan Chang Xiaochen Zhang Ge Song Jing Liu Chen Lin Jinjun Ye Jie Hu Lei Tang Zhengtao Ai | 2023 | Energy and Built Environment2023，4，5： | 0 |
| 10 | Revealing the Unusual Efficiency Enhancement of Organic Solar Cells with Polymer-Donor-Treated Cathode Contacts显示文摘The metal oxides with low trap density of states as the electron transport layer are crucial for the high performance of the organic solar cells(OSCs).It is universally acknowledged that modifying n-type metal oxide contacts with polymer donors will harm the carrier extraction on account of the mismatched energy level.However,we find that modifying interlayer consisting of the alcohol amines with some polymer donor additive can unusually enhance the performance of the OSCs.Compared with triethanolamine(TEA)passivated ZnO,TEA:polymer donor treated ZnO shows lower trap density and enhances electron mobility resulting in higher current density in OSC devices.Here,we reveal that the enhanced oxygen-defect passivation ability of TEA with polymer additive is attributed to the enhanced negative electrostatic potential of TEA owing to the hydrogen bond formation between the polymer and the hydroxyl group in TEA.This strategy that enhancing the negative electrostatic potential of the passivators for improving oxygen defect passivation can be extended to other types of organic electronic devices. | Zesheng Liu Yawen Li Xiaojun Zhao Yufan Zhu Yuze Lin | 2022 | Chinese Journal of Polymer Science2022，40，8： | 0 |
