1.Binary Nanoalloy Clusters A Case Study for FeCr Clusters
Author:  Shreemoyee Ganguly
Abstract: A study of FexCrybinary nanoalloy clusters is carried out for sizes n=x+y=13 and 55, the first two closed-shell structures. While for n=13, various compositions like x=12 and y=1; x=11 and y=2;x=10 and y=3 ; x=1 and y=12 are studied, for the larger size (n=55) the morphology of a Fe-rich cluster (Fe42Cr13) and a Cr-rich cluster (Fe13Cr42) are analysed. The potential energy surface of the nanoalloys are scanned thoroughly using an evolutionary genetic algorithm in conjunction with a density functional theory based first-principles method and the most stable clusters are picked upfor every size and composition. A definite hierarchy in Cr-Cr, Fe-Cr and Fe-Fe bonding strengths is seen to determine the stability of the clusters. Cr-Cr bonding is promoted over Fe-Cr bonding which in turn is preferred over Fe-Fe bonding in the nanoalloy systems.
2.Comparative study on safety knowledge of Deodrant or Antiperspirant among college students
Author:  Gargi Bhattacharjee
Abstract: The paper deals with the survey about the safety knowledge of college students on deodorant or antiperspirant. The college students have been chosen from colleges situated in urban and rural areas of West Bengal. A structured questionnaire has been developed and used for the survey on the under-graduate college students. Descriptive statistics and t-tests have been computed for analyzing the data statistically. The results show that there is a significant difference in safety knowledge between college students from rural and urban areas.
3.Control of Solar Powered Electric Vehicle Using Closed Loop Boost Converter
Author:  V. Kumar, R. Das, A. Basu, S. Mukherjee, I. Pradhan, S. Karak, P. Raman, and U. Kumar
Abstract: With the steep rise in new technologies in the field of digital communications and sensors, Mecha-tronics have availed us in coming up with new innovative designs for more sustainable physical systems. The forefront of all is the development of the electric vehicles to stop the carbon emissions from IC engines used in these days. In this proposed paper, we have designed a vehicle system using the Incremental Conductance Algorithm and a Closed-Loop Boost Converter and supported by a backup battery system.
4.Diabetes associated delay in wound healing and strategies for its management
Author:  Megha Jethwa,  Nagma Banjare, Tamal Sadhukhan, and Suvadra Das
Abstract: Diabetes one of the leading causes of deaths worldwide because of its secondary manifestations as discussed in this review. These manifestations are neuropathy, retinopathy, nephropathy, cardio-vascular system related disorder and alterations in normal wound healing process. Healing of skin and foot ulcers retards which give rise to chronic conditions around ulcers due to changes in the pathological conditions of wound in diabetes. This review discuss about these pathological changes and therapies which are currently available in the market. This review also explores some important research studies based on novel drug delivery system i.e. nanoparticle in diabetic wound healing.
5.Supramolecular assemblies for drug delivery
Author:  Narayani Ghosh
Abstract: Supramolecular chemistry is the branch of chemistry which emphasizes on the self-aggregation of a discrete number of molecules in a controlled and desired fashion. Supramolecular chemistry has gained much more attention in medicine for their enhance drug delivery to the target cells and therefore minimizing the off-target taken by the cell which causes side-effects. In this review, three major macrocyclic host molecules: block co-polymeric self- assembles, niosome, and cucurbit[n]urils (CBs)as for the application in biomedical applications has been presented. This family U is constructed using the families introduced by Boztas and Kumar, Kim and No. This family has the same correlation distribution as that of the well-known Gold sequences. So this family can be considered as another new class of Gold-like sequences.
