| 1 | FeP nanorod array:A high-efficiency catalyst for electroreduction of NO to NH3 under ambient conditions显示文摘Sustainable mitigation of the continuously rising concentration of NO contaminants is among the most urgent issues of this century.Ambient electrocatalytic conversion of NO into useful NH_(3)offers an attractive path toward achieving sustainable NO abatement and NH_(3)production simultaneously.However,its efficiency is challenged by the intense competition from hydrogen evolution reaction and relatively high energy barriers of NO activation.It is thus highly desirable to explore active electrocatalyst for NO reduction reaction and investigate the mechanisms on relevant surfaces.Herein,we introduce an FeP nanorod array on carbon cloth as a high-efficiency catalyst for NO electroreduction to NH3.In 0.2 M phosphate-buffered solution,this catalyst exhibits a low onset potential of-0.014 V.Moreover,it achieves a remarkable Faradaic efficiency of 88.49%and a large NH_(3)yield of 85.62μmol·h^(-1)cm^(-2),with durability for stable NO conversion over 12 h of electrolysis.The catalytic mechanism on FeP is investigated further by theoretical calculations. | Jie Liang Qiang Zhou Ting Mou Hongyu Chen Luchao Yue Yongsong Luo Qian Liu Mohamed S.Hamdy Abdulmohsen Ali Alshehri Feng Gong Xuping Sun | 2022 | Nano Research2022，15，5： | 1 |
| 3 | Genetic polymorphisms and phylogenetic analyses of the Ü-Tsang Tibetan from Lhasa based on 30 slowly and moderately mutated Y-STR loci显示文摘As a result of the expansion of old Tibet on the Qinghai-Tibet Plateau,Tibetans diverged into three main branches,Ü-Tsang,Amdo,and Kham Tibetan.Ü-Tsang Tibetans are geographically distributed across the wide central and western portions of the Qinghai-Tibet Plateau while Lhasa is the central gathering place for Tibetan culture.The AGCU Y30,a 6-dye fluorescence kit including 30 slowly and moderately mutated Y-STR loci,has been validated for its stability and sensitivity in different biomaterials and diverse Chinese populations(Han and other minorities),and widely used in the practical work of forensic science.However,the 30 Y-STR profiling of Tibetan,especially forÜ-Tsang Tibetan,were insufficient.We utilized the AGCU Y30 to genotype 577Ü-Tsang Tibetan unrelated males from Lhasa in the Tibet Autonomous Region of China to fill up the full and accurate Y-STR profiles.A total of 552 haplotypes were observed,536(97.10%)of which were unique.One hundred and ninety-four alleles were observed at 26 single copy loci and the allelic frequencies ranged from 0.0017 to 0.8180.For the two multi-copy loci DYS385a/b and DYS527a/b,64 and 36 allelic combinations were observed,respectively.The gene diversity(GD)values ranged from 0.3079 at DYS391 to 0.9142 at DYS385a/b and the overall haplotype diversity(HD)was 0.9998,and its discrimination capacity(DC)was 0.9567.The population genetic analyses demonstrated that LhasaÜ-Tsang Tibetan had close relationships with other Tibetan populations from Tibet and Qinghai,especially withÜ-Tsang Tibetan.From the perspective of Y haplogroups,the admixture of the southward Qiang people with dominant haplogroup O-M122 and the northward migrations of the initial settlers of East Asia with haplogroup D-M175 hinted the Sino-Tibetan homologous,thus,we could not ignore the gene flows with other Sino-Tibetan populations,especially for Han Chinese,to characterize the forensic genetic landscape of Tibetan. | Jiuyang Ding Haoliang Fan Yongsong Zhou Zhuo Wang Xiao Wang Xuheng Song Bofeng Zhu Pingming Qiu | 2022 | Forensic Sciences Research2022，7，2： | 0 |
