The chromatographic techniques play a crucial role in analyzing materials in pharmaceutical, biochemical, chemical, biomedical, and forensic sectors. High purity and quality reference standards are inevitable for the precise and accurate estimation of analytes from the sample matrices. Here, the influence of reference material on the chromatographic estimation of a highly volatile analyte, ethylene

Ultraviolet-C (UVC) radiation-based sanitization has globally gained enormous importance in the current COVID-19 (caused by SARS-COV-2 virus) pandemic situation. The effectiveness of radiation sanitization is quantified in terms of ‘radiation dose’, which in turn is derived from a radiometric parameter ‘irradiance’, measured using UVC radiometer. Metrological traceability of irradiance/dose measurement

The wide spread development of electro-optical system from telecommunication to space technologies has increased the demand of customized optics. In the present work, the design of a wide-angle laser range sensor has been presented. The dependence of field of view (FOV) and active area of sensor on effective focal length of the optical system has been demonstrated. A receiving optical system is designed

The problem of estimating the statistics of the distributed parameters of a transmission line which are random functions of time and spatial location is addressed in this paper. The main idea is to transform the spatial–temporal PDE (partial differential equation) problem into a purely temporal problem using spatial test functions and then apply first-order perturbation theory to express the random

The growing demand of traceable and reliable results of reference material in analytical chemistry can be illustrated with the growth in ISO 17034:2016. In this quality system, the application and development of CRM are highlighted because of its application in many field such as method validation, Proficiency tests, estimation of uncertainties and quality control & quality assurance. Over the past

A rectangular DRA with a Sierpinski fractal defected ground structure has been simulated and experimentally tested for UWB operation to be used in the detection of breast tumor using monostatic radar-based microwave imaging (MRMI). The proposed fractal DRA is designed to cover UWB characteristics (5.6–14.2 GHz) and high peak gain (5.8 dB). Then it is used as a sensor for extracting S-parameters from

In the present area, the outbreak of COVID-19, customer behavior have been seen toward their individual specific need, which encourages advanced-manufacturing industries to provide mass personalization of goods and services. The Covid-19 crises bring opportunities for industries and service providers to enhance their capability for a fault-free environment, zero failure, anti-fragile, and improve production

Abstract This paper presents an instrument to detect the presence of different biomolecules in the surroundings.

Drilling fluids are crucial to address issues such as loss of well control and integrity, decline in well productivity, and improper hydraulic balance under elevated temperature and pressure in situ conditions. These issues can compromise safety and hamper field development programs. One such drilling fluid formulation comprises of formate-based mud which has shown potential to provide better fluid
