| 1 | Applications of 2D-Layered Palladium Diselenide and Its van der Waals Heterostructures in Electronics and Optoelectronics显示文摘The rapid development of two-dimensional(2D)transition-metal dichalcogenides has been possible owing to their special structures and remarkable properties.In particular,palladium diselenide(PdSe_(2))with a novel pentagonal structure and unique physical characteristics have recently attracted extensive research inter-est.Consequently,tremendous research progress has been achieved regarding the physics,chemistry,and electronics of PdSe_(2).Accordingly,in this review,we recapitulate and summarize the most recent research on PdSe_(2),including its structure,properties,synthesis,and appli-cations.First,a mechanical exfoliation method to obtain PdSe_(2) nanosheets is introduced,and large-area synthesis strate-gies are explained with respect to chemical vapor deposition and metal selenization.Next,the electronic and optoelectronic properties of PdSe_(2) and related hetero-structures,such as field-effect transistors,photodetectors,sensors,and thermoelec-tric devices,are discussed.Subsequently,the integration of systems into infrared image sensors on the basis of PdSe_(2) van der Waals heterostructures is explored.Finally,future opportunities are highlighted to serve as a general guide for physicists,chemists,materials scientists,and engineers.Therefore,this com-prehensive review may shed light on the research conducted by the 2D material community. | Yanhao Wang Jinbo Pang Qilin Cheng Lin Han Yufen Li Xue Meng Bergoi Ibarlucea Hongbin Zhao Feng Yang Haiyun Liu Hong Liu Weijia Zhou Xiao Wang Mark HRummeli Yu Zhang Gianaurelio Cuniberti | 2021 | Nano-Micro Letters2021，13，9： | 1 |
| 2 | Hypercompact CRISPR–Cas12j2 (CasF) enables genome editing, gene activation, and epigenome editing in plants显示文摘CRISPR-Cas9,-Cas12a,-Cas12b,and-Cas13 have been harnessed for genome engineering in human and plant cells(Liu et al.,2022).However,the large size of these Cas proteins(e.g.190 kDa for SpCas9)makes them difficult to deliver into cells via a viral vector.The development of smaller Cas proteins will lead to reduced viral vector sizes that can be more widely adopted in versatile genome engineering systems.Recently,a CRISPR-Cas12j2(CasF)system was discovered in huge phages and developed into a hypercompact genome editor due to the small size of Cas12j2(80 kDa)(Pausch et al.,2020).Unfortunately,the gene editing efficiency of Cas12j2 in Arabidopsis protoplasts using ribonucleoprotein delivery was less than one percent(Pausch et al.,2020).Further optimization of this system is clearly required if CRISPR-Cas12j2-mediated editing in plant genomes is to be adopted by the plant sciences community. | Shishi Liu Simon Sretenovic Tingting Fan Yanhao Cheng Gen Li Aileen Qi Xu Tang Yang Xu Weijun Guo Zhaohui Zhong Yao He Yanling Liang Qinqin Han Xuelian Zheng Xiaofeng Gu Yiping Qi Yong Zhang | 2022 | Plant Communications2022，3，6： | 0 |
| 3 | CRISPR-Cas12a base editors confer efficient multiplexed genome editing in rice显示文摘Dear Editor,Many Cas9-derived base editors have been developed for precise C-to-T and A-to-G base editing in plants(Molla et al.,2021).They are typically based on a SpCas9 nickase or its engineered variants with altered protospacer adjacent motif(PAM)requirements(Molla et al.,2021).CRISPR-Cas12a enables highly efficient multiplexed genome editing in plants,and its T-rich PAM preference complements the G-rich PAM requirement of SpCas9 in genome targeting(Zhang et al.,2019,2021).Because of the lack of an efficient Cas12a nickase,it has been challenging to develop efficient Cas12a base editors.Nevertheless,Cas12a cytosine base editors(CBEs)and adenine base editors(ABEs)have been developed in mammalian cells(Li et al.,2018;Kleinstiver et al.,2019)with low DNA damage(Wang et al.,2020)because deactivated Cas12a(dCas12a)was used.However,efficient dCas12a base editors are yet to be developed in plants. | Yanhao Cheng Yingxiao Zhang Gen Li Hong Fang Simon Sretenovic Avery Fan Jiang Li Jianping Xu Qiudeng Que Yiping Qi | 2023 | Plant Communications2023，4，4： | 0 |
| 4 | Control of crystal growth to obtain needle-shaped violet phosphorus with excellent photocatalytic degradation performance显示文摘The control of crystal growth is important but challenging for multi-disciplinary research.Violet phosphorus,the most stable phosphorus allotrope,has recently been produced as a unique semiconducting layered structure.The crystal orientation and morphology bring extra performance due to its unique structure and anisotropy.Herein,the layered violet phosphorus has been controlled to grow along the c-axis to give tunable length up to centimeters with the assistance of tin,while the reported flat bulk ones with thickness are limited to micrometers.The as-produced needle-shaped violet phosphorus has also been demonstrated to significantly enhance the photocatalytic degradation of methyl orange pollutants due to its special crystallographic orientation.About 98.6%of methyl orange pollutants with a concentration of 50 ppm were degraded within 80 min under visible light conditions by needle-shaped violet phosphorus,which is much more effective than that of amorphous red phosphorus with only 14.1%degradation. | Mengting Jin Yanhao Wang Mengyue Gu Xuewen Zhao Rongzheng Zhao Yuhao Zhang Yonghong Cheng Jinying Zhang | 2023 | Nano Research2023，16，2： | 0 |
