| 1 | Vertically Aligned Silicon Carbide Nanowires/Boron Nitride Cellulose Aerogel Networks Enhanced Thermal Conductivity and Electromagnetic Absorbing of Epoxy Composites显示文摘With the innovation of microelectronics technology, the heat dissipation problem inside the device will face a severe test. In this work, cellulose aerogel(CA) with highly enhanced thermal conductivity(TC) in vertical planes was successfully obtained by constructing a vertically aligned silicon carbide nanowires(SiC NWs)/boron nitride(BN) network via the ice template-assisted strategy. The unique network structure of SiC NWs connected to BN ensures that the TC of the composite in the vertical direction reaches 2.21 W m^(-1) K^(-1) at a low hybrid filler loading of 16.69 wt%, which was increased by 890% compared to pure epoxy(EP). In addition, relying on unique porous network structure of CA, EP-based composite also showed higher TC than other comparative samples in the horizontal direction. Meanwhile, the composite exhibits good electrically insulating with a volume electrical resistivity about 2.35 × 10^(11) Ω cm and displays excellent electromagnetic wave absorption performance with a minimum reflection loss of-21.5 dB and a wide effective absorption bandwidth(<-10 dB) from 8.8 to 11.6 GHz. Therefore, this work provides a new strategy for manufacturing polymer-based composites with excellent multifunctional performances in microelectronic packaging applications. | Duo Pan Gui Yang Hala MAbo-Dief Jingwen Dong Fengmei Su Chuntai Liu Yifan Li Ben Bin Xu Vignesh Murugadoss Nithesh Naik Salah MEl-Bahy Zeinhom MEl-Bahy Minan Huang Zhanhu Guo | 2022 | Nano-Micro Letters2022，14，7： | 7 |
| 2 | Recent advances in chronic granulomatous disease显示文摘Chronic granulomatous disease(CGD)is an inherited defect of phagocyte function due to defective NADPH oxidase.Patients with CGD are not able to effectively clear the infections because of the defect in the phagocyte production of oxygen free radicals and are prone to recurrent bacterial and fungal infections.Inflammatory complications are also noted in CGD such as colitis,non-infective granulomas causing gastrointestinal or urinary tract obstruction,hemophagocytic lymphohistiocytosis,and arthritis.Studies on toll-like receptor pathways and neutrophil extracellular traps in CGD have shed light on the role of NADPH oxidase in the innate immunity and pathogenesis of infections in CGD.Some reports also indicate a reduction of memory B cells and defective production of functional antibodies in CGD.Though the exact mechanisms for non-infective inflammatory complications in CGD are not yet clear,studies on efferocytosis and defective autophagy with inflammasome activation have made a substantial contribution to our understanding of the pathogenesis of inflammation in CGD.We also discuss the clinical and molecular features of p40phox defects and a newer genetic defect,EROS.Clinical phenotypes of X-linked carriers of CYBB are also discussed. | Gummadi Anjani Pandiarajan Vignesh Vibhu Joshi Jitendra Kumar Shandilya Dharmagat Bhattarai Jyoti Sharma Amit Rawat | 2020 | Genes & Diseases2020，7，1： | 6 |
| 3 | Role of pomegranate and citrus fruit juices in colon cancer prevention显示文摘Colorectal cancer is the second leading cause of cancer-related deaths in the United States.Recent studies prove that though chemotherapeutic agents are being used for the treatment of colon cancer,they become non-effective when the cancer progresses to an invasive stage.Since consumption of certain dietary agents has been linked with various cancers,fruit juices have been investigated for their consistently protective effect against colon cancer.The unique biochemical composition of fruit juices is responsible for their anticancer properties.In this review,the chemo-preventive effect of fruit juices such as pomegranate and citrus juices against colon cancer are discussed.For this purpose,the bioavailability,in vitro and in vivo effects of these fruit juices on colorectal cancer are highlighted.Moreover,there is a scarcity of studies involving human trials to estimate the preventive nature of these juices against colon cancer.This review will support the need for more preclinical tests with these crude juices and their constituents in different colorectal cancer cell lines and also some epidemiological studies in order to have a better understanding and promote pomegranate and citrus juices as crusaders against colon cancer. | Saravana Kumar Jaganathan Muthu Vignesh Vellayappan Gayathri Narasimhan Eko Supriyanto | 2014 | World Journal of Gastroenterology2014，20，16： | 6 |
| 4 | Graph-theoretic algorithms for cyber-physical vulnerability analysis of power grid with incomplete information显示文摘A key focus recently has been on assessing therisk of a coordinated cyber-physical attack and minimizing the impact of a successful attack. Most of the cyberattackers will have limited system information and conventional power grid N-1 security analysis cannot be extended to assess the risk. Centrality measures are widely used in the network science and an attacker with incomplete information can use it to identify power system vulnerabilities by defining the system as a complex network but without real-time system measurements. This paper presents a graph theory based centrality indices for vulnerability assessment of the power system due to various bus and branch contingencies using limited system information and provides a preliminary defense mechanism to prevent such an attack. Proposed work answers the fundamental question of possible attack scenarios by balancing risk(limited information with low risk to get caught orhigh risk attack to access more system information) and impact(identifying contingencies with maximal impact on system operation). Statistical comparisons are made between the graph theory measures compared to the corresponding DC power flow based N-X linear sensitivity measures. A unified N-X centrality based performance index is proposed and validated against the AC power flow based performance index by doing the real-time simulations of an N-3 attack scenario. Defensive mechanisms using topology-based performance indices are also presented. | Anurag K.SRIVASTAVA Timothy A.ERNSTER Ren LIU Vignesh G.KRISHNAN | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，5： | 4 |
| 5 | Sol-Gel Coating with 3-Mercaptopropyltrimethoxysilane as Precursor for Corrosion Protection of Aluminium Metal显示文摘Sol—gel coatings offer a number of advantages over other methods of protection for metallic materials.In the present work,3-mercaptopropyltrimethoxysilane(MPTS) was used as the precursor for sol—gel coating on aluminium metal.The gelation of MPTS sol—gel was characterized by Fourier transform infrared spectroscopy(FT-IR) studies.The formed film was found to be stable up to 350 ℃ as evident from thermogravimetric analysis.X-ray diffraction study and scanning electron microscopy supported the formation of MPTS coating on aluminium surface while the characterization of the coating was done by FT-IR studies.The corrosion inhibition potential of the sol—gel coatings on metal in 3.5%(w/v) of NaCI solution was assessed as a function of different concentrations of MPTS using electrochemical polarization and impedance measurements.The corrosion inhibition efficiency was found to increase with increasing MPTS concentration.The results of the study unravel the use of MPTS as a precursor in the formation of sol—gel coating over aluminium surface so as to protect the metallic surface from corrosion in neutral environment. | Rajendran Babhu Vignesh Thomas Nesakumar Jebakumar Immanuel Edison Mathur Gopalakrishnan Sethuraman | 2014 | Journal of Materials Science & Technology2014，30，8： | 4 |
| 6 | Chemopreventive effect of apple and berry fruits against colon cancer显示文摘Colon cancer arises due to the conversion of precancerous polyps(benign)found in the inner lining of the colon.Prevention is better than cure,and this is very true with respect to colon cancer.Various epidemiologic studies have linked colorectal cancer with food intake.Apple and berry juices are widely consumed among various ethnicities because of their nutritious values.In this review article,chemopreventive effects of these fruit juices against colon cancer are discussed.Studies dealing with bioavailability,in vitro and in vivo effects of apple and berry juices are emphasized in this article.A thorough literature survey indicated that various phenolic phytochemicals present in these fruit juices have the innate potential to inhibit colon cancer cell lines.This review proposes the need for more preclinical evidence for the effects of fruit juices against different colon cancer cells,and also strives to facilitate clinical studies using these juices in humans in large trials.The conclusion of the review is that these apple and berry juices will be possible candidates in the campaign against colon cancer. | Saravana Kumar Jaganathan Muthu Vignesh Vellayappan Gayathri Narasimhan Eko Supriyanto Dyah Ekashanti Octorina Dewi Aqilah Leela T Narayanan Arunpandian Balaji Aruna Priyadarshini Subramanian Mustafa Yusof | 2014 | World Journal of Gastroenterology2014，20，45： | 3 |
| 7 | Manipulation of blue TADF top-emission OLEDs by the first-order optical cavity design:toward a highly pure blue emission and balanced charge transport显示文摘The broad luminescence spectrum of a thermally activated delayed fluorescence(TADF)organic light-emitting diode(OLED)is a critical issue to overcome for its application in high-color-purity displays.Herein,a novel device structure that utilizes the first-order microcavity optical mode with a high radiance intensity is demonstrated to solve this problem by considering the charge transport properties through the analysis of hole-only and electron-only devices.In addition,by tuning the optical interference near the semitransparent top cathode layers consisting of thin silver and organic capping layers,light extraction is increased by nearly 2 times compared to the device without a capping layer.Consequently,the optimized blue TADF top-emission OLED exhibits much lower full width at half-maximum,higher maximum current efficiency,and external quantum efficiency compared to the device before optimization.This approach is expected to provide a simple but effective way to further enhance the spectral purity of the conventional TADF-based OLEDs. | WANQI REN KYUNG ROCK SON TAE HOON PARK VIGNESH MURUGADOSS TAE GEUN KIM | 2021 | Photonics Research2021，9，8： | 3 |
| 8 | Identification of SNP and InDel variations in the promoter and 5′ untranslated regions of γ-tocopherol methyl transferase(ZmVTE4) affecting higher accumulation of α-tocopherol in maize kernel显示文摘Deficiency of vitamin-E or tocopherol causes neurological and cardiovascular disorders in humans. Though maize kernel is rich in total tocopherol, the level of α-tocopherol possessing the highest vitamin-E activity is low. Mutant allele of ZmVTE4 with deletion of 7 bp and 118 bp (0/0: most favorable haplotype) in 5′UTR and promoter region, respectively significantly enhances α-tocopherol in maize kernel than wild type haplotype (7/118).α- tocopherol estimation in 15 diverse inbreds revealed that mean α-/γ-tocopherol and α-/ total-tocopherol was much higher in genotypes with favorable haplotype (1.51 and 0.41) than unfavorable class (0.19 and 0.13), respectively. However even within favorable class,α- tocopherol ranged from 4.76 to 30.07 μg g 1. Sequence analysis of part of 5′UTR and promoter of ZmVTE4 among the genotypes with favorable haplotype revealed 14 SNPs (SNP1 to SNP14) and eight InDels (InDel1 to InDel8). SNP7 at 606 bp (G to A), and InDels viz., InDel1 (27 bp), InDel4 (27 bp) and InDel8 (14 bp) differentiated low and high α-tocopherol accumulating inbreds with favorable haplotype. Hence the newly identified SNP and InDels in addition to the already reported InDels can be useful in selection of favorable genotypes with higher α-tocopherol in maize. | Abhijit Kumar Das Rashmi Chhabra Vignesh Muthusamy Hema Singh Chauhan Rajkumar Uttamrao Zunjare Firoz Hossain | 2019 | The Crop Journal2019，7，4： | 2 |
| 9 | Genetics of severe combined immunodeficiency显示文摘Severe Combined Immunodeficiency(SCID)is an inherited group of rare,lifethreatening disorders due to the defect in T cell development and function.Clinical manifestations are characterised by recurrent and severe bacterial,viral,and fungal opportunistic infections that start from early infancy period.Haematopoietic stem cell transplantation(HSCT)is the treatment of choice.The pattern of inheritance of SCID may be X-linked or autosomal recessive.Though the diagnosis of SCID is usually established by flow cytometry-based tests,genetic diagnosis is often needed for genetic counselling,prognostication,and modification of pre-transplant chemotherapeutic agents.This review aims to highlight the genetic aspects of SCID. | Rajni Kumrah Pandiarajan Vignesh Pratap Patra Ankita Singh Gummadi Anjani Poonam Saini Madhubala Sharma Anit Kaur Amit Rawat | 2020 | Genes & Diseases2020，7，1： | 2 |
| 10 | Impact of gut microbiome in the development and treatment of pancreatic cancer:Newer insights显示文摘The gut microbiome plays an important role in the variation of pharmacologic response.This aspect is especially important in the era of precision medicine,where understanding how and to what extent the gut microbiome interacts with drugs and their actions will be key to individualizing therapy.The impact of the composition of the gut microbiome on the efficacy of newer cancer therapies such as immune checkpoint inhibitors and chimeric antigen receptor T-cell treatment has become an active area of research.Pancreatic adenocarcinoma(PAC)has a poor prognosis even in those with potentially resectable disease,and treatment options are very limited.Newer studies have concluded that there is a synergistic effect for immunotherapy in combination with cytotoxic drugs,in the treatment of PAC.A variety of commensal microbiota can affect the efficacy of conventional chemotherapy and immunotherapy by modulating the tumor microenvironment in the treatment of PAC.This review will provide newer insights on the impact that alterations made in the gut microbial system have in the development and treatment of PAC. | Ayrton I Bangolo Chinmay Trivedi Ishan Jani Silvanna Pender Hirra Khalid Budoor Alqinai Alina Intisar Karamvir Randhawa Joseph Moore Nicoleta De Deugd Shaji Faisal SuchithBoodgere Suresh Parva Gopani Vignesh K Nagesh Tracy Proverbs-Singh Simcha Weissman | 2023 | World Journal of Gastroenterology2023，29，25： | 2 |

| 12 | Highly transmitted silver nanowires-SWCNTs conductive flexible film by nested density structure and aluminum-doped zinc oxide capping layer for flexible amorphous silicon solar cells显示文摘Indium tin oxide(ITO)is widely used in transparent conductive films(TCFs);however,several disadvan-tages,such as high cost and toxicity of indium,limit its applications.Therefore,it is necessary to develop other materials that can replace ITO.Silver nanowires or single walled carbon nanotubes(SWCNTs)have attracted considerable interest owing to their unique electrical,optical,and thermal stabilities,and thus,they are ideal for transparent electrodes for flexible or stretchable devices.In this study,we develop a novel architecture of composite TCFs on a polyethylene naphthalate(PEN)flexible substrate.Herein,the silver nanowires-SWCNTs films with nested density structure were fabricated through ultrasonic spraying technology by varying the spraying width.For achieving enhanced transmittance,we combined the larger irregular grids and holes with fewer nanowires stacked in the longitudinal direction,more optical chan-nels,and good carrier transport.Thereafter,aluminum-doped zinc oxide(AZO)was used as capping to the structure for enhancing the optical properties of the TCFs.The silver nanowires-SWCNTs/AZO(ASA)bilayer was obtained in the optimized architecture,which showed superior optoelectronic performance to that shown by commercial ITO with a high optical transmittance of 92%at the wavelength of 550 nm and low sheet resistance of 17/sq.In the specially structured conductive film,the significant improvement in the transmittance and uniformity of the sheet resistance was attributed to the effective nanowire junc-tion contact compared to that in ordinary structure of silver nanowires,which reduced the mean density of small clusters of nanowires.Compared with the silver nanowires-SWCNTs films,the ASA bilayer film exhibited excellent resistance to boiling,mechanical bending(10,000 cycles),and CO_(2)plasma.Moreover,the sheet resistance of ASA changed slightly after the tape tests,thereby illustrating a strong adhesion to the PEN substrate after the enclosure of AZO.Meanwhile,the AZO capping layer can enhance the op-tical transmittance between 600 and 1500 nm.In addition,the amorphous silicon photovoltaic devices with flexible ASA TCFs exhibited a power conversion efficiency(PCE)of 8.67%.After bending for 3000 times,the PCE was decreased to 8.20%,thereby demonstrating the potential of developed films to replace traditional ITO. | Shunliang Gao Xiaohui Zhao Qi Fu Tianchi Zhang Jun Zhu Fuhua Hou Jian Ni Chengjun Zhu Tiantian Li Yanlai Wang Vignesh Murugadoss Gaber A.M.Mersal Mohamed M.Ibrahim Zeinhom M.El-Bahy Mina Huang Zhanhu Guo | 2022 | Journal of Materials Science & Technology2022，，31： | 2 |
