Abstract: Aqueous biphasic system (ABS) consists of a tri block copolymer PEG-PPG-PEG and
Polyvinylpyrrolidone (PVP) was designed. The phase diagram of the polymer-polymer system
was constructed by turbidometric titration method at 298 K. The newly developed ABS was employed for the possible analytical application of separation and recovery of an important catalyst
Abstract: Nanotechnology is the rapidly developing and innovative field in many areas of human activity.
They have wide range of contribution in the medical field. Nanotechnology deals with nano-meter
sized objects in the field of material science, nanodevices etc. The nanomaterials are the most advanced in scientific knowledge and in commercial applications due to their size-dependent physical
and chemical properties. Nanoparticles have important properties e.g. unique size, shape, biocompatibility, and selectivity. Optical and magnetic effects of nanomaterials are most important
for biological applications. Hybrid bionanomaterials can be applied to build novel electronic, optoelectronics and memory devices. This brief review explains to summarise various application of
nanoparticles in medical field and biotechnology.
Abstract: Plasmonic nano-structures have received a great deal of attention lately because of their exceptional ability to confine light at the nanoscale. The highly enhanced E-M field around the plasmonic structure is frequently confined on a length scale of 10~50 nm. Furthermore, the enhanced E-M field varies greatly depending on the size, shape, periodicity, and composition of the nanoparticles (NPs). To understand the light-matter interaction at the nanometer level, an experimental tool that can directly visualize the nanoscale optical phenomena is required. In this respect, Cathodoluminescence (CL) spectroscopy and imaging technique have emerged as a novel experimental tool for directly visualising the local field enhancement around the NPs. We use CL spectroscopy and imaging to investigate the plasmonic behaviour of a gold (Au) nano particle with decahedral or pentagonal bi-pyramidal geometry.
Abstract: A model of two-dimensional damped harmonic oscillator affected by time dependent magnetic field
in time dependent noncommutative space was studied in an earlier communication [Phys. Scr. 96
(2021) 125224]. In this article, the same model is considered to show that, for a suitable explicit
choices of damping and magnetic field, it is possible to import a periodicity to the time evolution
of the energy expectation value of the model system.
Abstract: A database is a computer-based system for managing data. Several database work systems have their
own set of rules and procedures. The data is organised at many levels. The database management system is
based on the principles of data dissemination and data control, all of which can be accomplished by an
individual with or without risk through proper and helpful programming. Database management systems have
become increasingly popular in recent years. These types of data arrangements give critical ways of
simultaneous communication for studying work and improving performance in all aspects of human life. The
essay will provide you a better and deeper understanding of how database management systems are used in
numerous aspects of human existence.
