| 1 | A Novel Masking Scheme for SM3 Based MAC显示文摘The Chinese hash algorithm SM3 is verified to be secure enough,but improper hardware implementation may lead to leakage.A masking scheme for SM3 algorithm is proposed to ensure the security of SM3 based Message Authentication Code(MAC).Our scheme was implemented in hardware,which utilizes hardware oriented secure conversion techniques between boolean and arithmetic masking.Security evaluation based on SAKURA-G FPGA board has been done with 2000 power traces from 2000 random plaintexts with random plaintext masks and random key masks.It has been verified that the masked SM3 hardware implementation shows no intermediate value leakage as expected.Our masked SM3 hardware can resist first-order correlation power attack(CPA) and collision correlation attack. | QU Kaige WU Liji WANG An REN Yanting ZHANG Xiangmin | 2015 | China Communications2015，12，6： | 0 |
| 2 | Enhancing multifunctional photocatalysis with acetate-assisted cesium doping and unlocking the potential of Z-scheme solar water splitting显示文摘Graphitic carbon nitride(g-C_(3)N_(4))has been extensively doped with alkali metals to enlarge photocatalytic output,in which cesium(Cs)doping is predicted to be the most efficient.Nevertheless,the sluggish diffusion and doping kinetics of precursors with high melting points,along with imprecise regulation,have raised the debate on whether Cs doping could make sense.For this matter,we attempt to confirm the positive effects of Cs doping on multifunctional photocatalysis by first using cesium acetate with the character of easy manipulation.The optimized Csdoped g-C_(3)N_(4)(CCN)shows a 41.6-fold increase in visible-light-driven hydrogen evolution reaction(HER)compared to pure g-C_(3)N_(4) and impressive degradation capability,especially with 77%refractory tetracycline and almost 100%rhodamine B degradedwithin an hour.The penetration ofCs+is demonstrated to be a mode of interlayer doping,and Cs–N bonds(especially with sp^(2) pyridine N in C═N–C),along with robust chemical interaction and electron exchange,are fabricated.This atomic configuration triggers the broadened spectral response,the improved charge migration,and the activated photocatalytic capacity.Furthermore,we evaluate the CCN/cadmium sulfide hybrid as a Z-scheme configuration,promoting the visible HER yield to 9.02 mmol g^(−1) h^(−1),which is the highest ever reported among all CCN systems.This work adds to the rapidly expanding field of manipulation strategies and supports further development of mediating served for photocatalysis. | Mengmeng Ma Jingzhen Li Xiaogang Zhu Kong Liu Kaige Huang Guodong Yuan Shizhong Yue Zhijie Wang Shengchun Qu | 2024 | Carbon Energy2024，6，3： | 0 |
| 3 | 环形RNA结构与降解调控PKR激活和天然免疫反应显示文摘文章简介环形RNA(circ RNA)来自RNA聚合酶II的转录本并以共价键形成闭环结构。虽然在哺乳动物细胞中普遍表达,但是绝大部分环形RNA的功能仍不清楚。外显子反向剪接成环发生效率很低,但产生的环形RNA非常稳定。该研究证明环形RNA分子倾向于形成长度为16-26bp双链RNA茎环结构,可以结合并抑制天然免疫因子PKR的活性。 | 刘楚霄 李响 南芳 Shan Jiang Xiang Gao Si-Kun Guo Wei Xue Yange Cui Kaige Dong Huihua Ding Bo Qu Zhaocai Zhou 沈南 杨力 陈玲玲 | 2020 | 科学新闻2020，，2： | 0 |
| 4 | HG-Induced sEVs Mediate Biomechanics of HK-2 Cells显示文摘Small extracellular vesicles (sEVs) participate in the pathological progression of high glucose (HG)-induced kidney injury, which is closely related to diabetic nephropathy. How sEVs specifically mediate the cell biomechanics underlying HG injury is unclear. Herein, we utilized a versatile atomic force microscope to determine the contributions of sEVs in HG-induced cellular injury. The sEVs extracted from the culture medium of human proximal tubule kidney (HK-2) cells treated by HG for 72 h (HG-induced sEVs) were verified and analyzed by multiple techniques, and the results indicated the effective production and the effect of dehydration on the shape of HG-induced sEVs. Further investigation on the morphologies of HK-2 cells treated by HG-induced sEVs showed that the surface roughness of the HK-2 cells increased, and their pseudopodia transitioned from lamellipodia to filopodia, with almost doubled mean pseudopodia length. Quantitative analysis of the mechanical responses of the cells revealed that the mean Young’s modulus increased by 26.2%, and the mean adhesion decreased by 36.8%. The indirect mediation of cellular biomechanics guided by HG-induced sEVs was evaluated by comparing it with previously studied direct HG injury. The HG-induced sEVs caused a greater reduction in cell adhesion and an increase in Young’s modulus compared with direct HG stimulation. This work suggested the ability of HG-induced sEVs to elicit specific biomechanical responses during HG injury, advancing the understanding of the injury mechanism caused by HG. The comparison of the cellular biomechanics between direct and indirect HG stimulations through HG-induced sEVs can be beneficial for the diagnosis and treatment of kidney injury. | Fan Yang Jiajia Wang Tuoyu Ju Shuwei Wang Kaige Qu Zhengxun Song Yujuan Chen Zuobin Wang | 2023 | Nanomanufacturing and Metrology2023，6，4： | 0 |
| 5 | Magnetic Ganoderma Lucidum Spores(mGLS):A Novel Regulatable Targeted Drug Delivery System显示文摘In the past decades,many materials have been studied as carriers for targeted drug delivery.However,there is a need for utilizable and selective carrier materials with few side effects.Here,the magnetic Ganoderma Lucidum Spores(mGLS)as a highly efficient targeted drug delivery carrier were explored.Then the regulatable targeted drug delivery system was verified by loading and releasing of the 5-Fluorouracil(5-FU).The results showed that the maximum of the loaded 5-FU reached 250.23 mg·g^(−1)in the mGLS.The cumulative release of the 5-FU for the drug delivery system could reach 80.11%and 67.14%in the PBS and HCl after 48 h,respectively.In addition,this system showed the good pharmacokinetic properties in vivo.After 12 h,the blood concentration in the 5-FU@mGLS group kept at 5.3µg·mL^(−1)and was four times higher than that in the 5-FU group.In summary,the GLS as a natural microscale core-shell structures appears the striking application in carrier material for oral drug delivery. | Bin Han Zhankun Weng Yuhan Wu Xin Zhao Jingmei Li Qinhan Zhang Kaige Qu Bojian Liang Fenguo Zhou Guixia Liu Zuobin Wang | 2021 | Journal of Bionic Engineering2021，18，4： | 0 |
| 6 | State-of-the-art advances in vacancy defect engineering of graphitic carbon nitride for solar water splitting显示文摘Developing low-cost,efficient,and stable photocatalysts is one of the most promising methods for large-scale solar water splitting.As a metal-free semiconductor material with suitable band gap,graphitic carbon nitride(g-C_(3)N_(4))has attracted attention in the field of photocatalysis,which is mainly attributed to its fascinating physicochemical and photoelectronic properties.However,several inherent limitations and shortcomings—involving high recombination rate of photocarriers,insufficient reaction kinetics,and optical absorption—impede the practical applicability of g-C_(3)N_(4).As an effective strategy,vacancy defect engineering has been widely used for breaking through the current limitations,considering its ability to optimize the electronic structure and surface morphology of g-C_(3)N_(4) to obtain the desired photocatalytic activity.This review summarizes the recent progress of vacancy defect engineered g-C_(3)N_(4) for solar water splitting.The fundamentals of solar water splitting with g-C_(3)N_(4) are discussed first.We then focus on the fabrication strategies and effect of vacancy generated in g-C_(3)N_(4).The advances of vacancy-modified g-C_(3)N_(4) photocatalysts toward solar water splitting are discussed next.Finally,the current challenges and future opportunities of vacancy-modified g-C_(3)N_(4) are summarized.This review aims to provide a theoretical basis and guidance for future research on the design and development of highly efficient defective g-C_(3)N_(4). | Jie Li Kaige Huang Yanbin Huang Yumin Ye Marcin Ziółek Zhijie Wang Shizhong Yue Mengmeng Ma Jun Liu Kong Liu Shengchun Qu Zhi Zhao Yanjun Zhang Zhanguo Wang | 2023 | Journal of Semiconductors2023，44，8： | 0 |
