| 1 | Recent progress of precious-metal-free electrocatalysts for efficient water oxidation in acidic media显示文摘The realization of efficient oxygen evolution reaction(OER) is critical to the development of multiple sustainable energy conversion and storage technologies, especially hydrogen production via water electrolysis. To achieve the massive application of hydrogen energy and mass-scale hydrogen production from water splitting drives the pursuit of competent precious-metal-free electrocatalysts in acidic media, where the hydrogen evolution reaction(HER) is more facilitated. However, the development of high-efficient and acid-stable OER electrocatalysts, which are robust to function stably at high oxidation potentials in the acidic electrolyte, remains a great challenge. This article contributes a focused, perceptive review of the up-to-date approaches toward this emerging research field. The OER reaction mechanism and fundamental requirements for oxygen evolution electrocatalysts in acid are introduced. Then the progress and new discoveries of precious-metal-free active materials and design concepts with regard to the improvement of the intrinsic OER activity are discussed. Finally, the existing scientific challenges and the outlooks for future research directions to the fabrication of emerging, earth-abundant OER electrocatalysts in acid are pointed out. | Samarjeet Singh Siwal Wenqiang Yang Qibo Zhang | 2020 | Journal of Energy Chemistry2020，29，12： | 2 |
| 2 | Alteration in the expression of microRNA-21 regulated target genes:Role in breast cancer显示文摘Breast cancer,also recognized as the principal cause of cancer-related deaths among women,is the second most familiar and prevalent form of cancer.New diagnostic and prognostic biomarkers that are highly specific are urgently needed for its early prognosis.MicroRNAs(miRNAs),a class of non-coding RNAs,are known to control the biological processes involving transcription,post-transcriptional and covalent modifications,splicing,translation,cell differentiation,proliferation,apoptosis,cancer progression,and invasion.Any dysregulation in miRNA expression,demonstrating their oncogenic and tumor-suppressive functions,contributes to cancer progression.MicroRNA-21(miR-21),an‘onco-miR’in breast cancer,is involved in tumor progression and metastasis by suppressing the activity of the target gene via its interaction with the 3’UTR of the target gene.The upregulation of miR-21 is observed in many instances of breast cancer.Our review aims to summarize the current understanding of miR-21 in the regulation of important cellular functions via regulation of its target genes.We discuss its biosynthesis,oncogenic function in breast cancer,and different methods used for its detection.This will increase the current understanding of the role of miR-21 in breast cancer tumorigenesis,which will offer a perception of using miR-21 as an early detection molecular prognostic and diagnostic biomarker and as a therapeutic target in breast cancer care. | PRIYANKA THAKUR REENA V.SAINI ANIL K.CHHILLAR NEERAJ K.SAINI VIJAY KUMAR THAKUR SAMARJEET SINGH SIWAL ADESH K.SAINI | 2022 | BIOCELL2022，46，2： | 1 |

| 8 | Antimicrobial Materials: New Strategies to Tackle Various Pandemics显示文摘Coronaviruses are responsible for a developing budgetary,human and fatality trouble,as the causative factor of infections,for example,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).It has been well recognized that SARS-CoV-2 may survive under severe atmosphere circumstances.Hence,efficient containment approaches,for example,sanitizing,are crucial.Commonly,living compounds contribute a substance of chemical heterogeneity,with antiviral movement,and therefore can have efficacy as therapeutic tools toward coronavirus diseases.Here,in this review article,we have described the antimicrobialbased materials,which can be used to inhibit the spreading of the COVID-19.We have categorized these materials in three sections;(i)antimicrobial wall paint,(ii)antimicrobial papers and(iii)antimicrobial materials surface coating to be utilized as the antimicrobial-based materials for controlling the COVID-19.In the last section,we have given the concluding remarks with prospects in this area. | Samarjeet Singh Siwal Qibo Zhang Adesh Kumar Saini Vijay Kumar Thakur | 2020 | Journal of Renewable Materials2020，8，12： | 0 |
