| 2 | Scalable and ultrafast epitaxial growth of single-crystal graphene wafers for electrically tunable liquid-crystal microlens arrays显示文摘The scalable growth of wafer-sized single-crystal graphene in an energy-efficient manner and compatible with wafer process is critical for the killer applications of graphene in high-performance electronics and optoelectronics. Here, ultrafast epitaxial growth of single-crystal graphene wafers is realized on singlecrystal Cu90Ni10(1 1 1) thin films fabricated by a tailored two-step magnetron sputtering and recrystallization process. The minor nickel(Ni) content greatly enhances the catalytic activity of Cu, rendering the growth of a 4 in. single-crystal monolayer graphene wafer in 10 min on Cu90Ni10(1 1 1), 50 folds faster than graphene growth on Cu(1 1 1). Through the carbon isotope labeling experiments, graphene growth on Cu90Ni10(1 1 1) is proved to be exclusively surface-reaction dominated, which is ascribed to the Cu surface enrichment in the Cu Ni alloy, as indicated by element in-depth profile. One of the best benefits of our protocol is the compatibility with wafer process and excellent scalability. A pilot-scale chemical vapor deposition(CVD) system is designed and built for the mass production of single-crystal graphene wafers, with productivity of 25 pieces in one process cycle. Furthermore, we demonstrate the application of single-crystal graphene in electrically controlled liquid-crystal microlens arrays(LCMLA), which exhibit highly tunable focal lengths near 2 mm under small driving voltages. By integration of the graphene based LCMLA and a CMOS sensor, a prototype camera is proposed that is available for simultaneous light-field and light intensity imaging. The single-crystal graphene wafers could hold great promising for highperformance electronics and optoelectronics that are compatible with wafer process. | Bing Deng Zhaowei Xin Ruiwen Xue Shishu Zhang Xiaozhi Xu Jing Gao Jilin Tang Yue Qi Yani Wang Yan Zhao Luzhao Sun Huihui Wang Kaihui Liu Mark H.

| 3 | In situ TEM revealing the effects of dislocations on lithium-ion migration in transition metal dichalcogenides显示文摘The two-dimensional (2D) structure of layered transition metal dichalcogenides (TMDs) provides unusual physical properties [1,2]and chemical reactivity [3,4], which can be influenced by defects such as dislocations [5,6]. For example, dislocations can act as nucleation sites for the onset of deformation when subjected to stress [7]. | Ruiwen Shao Chengkai Yang Chen Yang Shulin Chen Weikang Dong Bairong Li Xiumei Ma Jing Lu Lixin Dong Peng Gao Dapeng Yu | 2021 | Journal of Energy Chemistry2021，30，7： | 1 |
| 4 | Effects of Overwintering on the Survival and Vector Competence of Aedes albopictus in the Urban Life Cycle of Dengue Virus in Guangzhou,China显示文摘The Pearl River Delta,where Aedes albopictus(Ae.albopictus)is the only vector for dengue transmission,has exhibited one of the highest dengue burdens in southern China in recent decades.However,whether dengue virus(DENV)can overwinter in Ae.albopictus in the Pearl River Delta has not been determined to date.In this study,300 field-derived Ae.albopictus mosquitoes from Guangzhou that were infected with the predominant endemic DENV-1 strain were investigated under simulated urban balcony environment from October 16,2016,to June 16,2017.The vertical transmission of DENV in the infected overwintering Ae.albopictus was analyzed.The DENV infected overwintering mosquitoes were evaluated for viral load at nine-time points using reverse transcription-quantitative PCR.The vector competence of the infected overwintering Ae.albopictus was also investigated by using suckling mice.Adult mosquitoes and larvae were found during the observation period.The vertical transmission of DENV-1 was documented.The DENV-1-positive rates between overwintering males and females had no difference.The proportion of DENV-1-positive overwintering mosquitoes decreased over time and had no difference beyond three months after the experiment.Overwintering mosquitoes can spread DENV-1 to hosts.No engorged mosquitoes at an ambient temperature below 15℃were observed.The ratio of engorged mosquitoes was positively correlated with the ambient temperature ranging from 15 to 30℃.Our results demonstrated that DENV can overwinter in Ae.albopictus in the Pearl River Delta,Ae.albopictus is the competent vector for DENV,and maintain autochthonous dengue outbreaks in the Pearl River Delta through vertical transmission. | Yue Chen Ronghua Chen Jianrong Gao Chunyuan Li Jun Liu Zhijian Zhou Ruiwen Ren | 2021 | Virologica Sinica2021，36，4： | 1 |

| 6 | In situ growth of phosphorized ZIF-67-derived amorphous CoP/Cu_(2)O@CF electrocatalyst for efficient hydrogen evolution reaction显示文摘Transition metal phosphides have been extensively studied for catalytic applications in water splitting.Herein,we report an in situ phosphorization of zeolitic imidazole frameworks(ZIF-67)to generate amorphous cobalt phosphide/ZIF-67 heterojunction on a self-supporting copper foam(CF)substrate with excellent performance for hydrogen evolution reaction(HER).The needleleaf like copper hydroxide was anchored on CF surface,which acted as implantation to grow ZIF-67.The intermediate product was phosphorized to obtain final electrocatalyst(CoP/Cu_(2)O@CF)with uniform particle size,exhibiting a rhombic dodecahedron structure with wrinkles on the surface.The electrochemical measurement proved that CoP/Cu_(2)O@CF catalyst exhibited excellent HER activity and long-term stability in 1.0 mol·L^(–1)KOH solution.The overpotential was only 62 mV with the Tafel slope of 83 mV·dec^(–1)at a current density of 10 mA·cm^(–2),with a large electrochemical active surface area.It also showed competitive performance at large current which indicated the potential application to industrial water electrolysis to produce hydrogen.First-principle calculations illustrated that benefit from the construction of CoP/ZIF-67 heterojunction,the d-band center of CoP downshifted after bonding with ZIF-67 and the Gibbs free energy(ΔGH*)changed from–0.18 to–0.11 eV,confirming both decrease in overpotential and excellent HER activity.This work illustrates the efficient HER activity of CoP/Cu_(2)O@CF catalyst,which will act as a potential candidate for precious metal electrocatalysts. | Ruiwen Qi Xiao Liu Hongkai Bu Xueqing Niu Xiaoyang Ji Junwei Ma Hongtao Gao | 2023 | Frontiers of Chemical Science and Engineering2023，17，10： | 0 |
| 7 | Supplementation of alanine improves biomass accumulation and lipid production of Chlorella pyrenoidosa by increasing the respiratory and metabolic processes显示文摘The function of exogenous alanine(Ala)in regulating biomass accumulation,lipid production,photosynthesis,and respiration in Chlorella pyrenoidosa was studied.Result shows that the supplementation of Ala increased C.pyrenoidosa biomass and lipid production in an 8-d batch culture.The concentration of 10 mmol/L of Ala was optimum and increased the microalgal cell biomass and lipid content by 39.3%and 21.4%,respectively,compared with that in the control(0-mmol/L Ala).Ala supplementation reduced photosynthetic activity while boosting respiratory activity and pyruvate levels,indicating that C.pyrenoidosa used exogenous Ala for biomass accumulation through the respiratory metabolic process.The accelerated respiratory metabolism due to Ala supplementation elevated the substrate pool and improved the lipogenic gene expression,promoting lipid production at last.This study provided a novel method for increasing biomass accumulation and lipid production and elucidated the role of Ala in regulating lipid production. | Yongfu LI Tianze ZHAO Wei SUN Ruiwen GAO Guangyuan MA | 2024 | Journal of Oceanology and Limnology2024，42，2： | 0 |
