Evaluating Rutting Susceptibility of Bituminous Mixes using Indigenously Developed IIT KGP Rut Tester
Abstract: Rutting is the major mode of distress affecting the service life and performance of bituminous pavements. Rutting occurs due to excessive stresses on subgrade, inadequate strength of bituminous mix, inadequate thickness of pavement layers or poor construction methods. Among these causes, quality of bituminous mix is one of the main factors that contribute towards rutting failure. The link between laboratory testing and potential field performance of bituminous mixes is very …

Biopolymer-Based Flocculation for Microplastic Removal: Fenugreek and Okra as Sustainable Alternatives to Synthetic Flocculants
Abstract: Microplastic pollution has emerged as a persistent global environmental concern due to its widespread presence in aquatic ecosystems and potential implications for food chains and human health. Conventional removal approaches, particularly the use of synthetic flocculants such as polyacrylamide (PAM), have demonstrated high removal efficiencies in water treatment applications. However, their use is often associated with environmental concerns including toxicity, non-biodegradable residues, and energy-intensive production processes. In this context, the …

Thin Film Technology in Sensor Manufacturing – A Technical Discussion
Abstract: Thin‑film technology has become the cornerstone of modern sensor manufacturing, enabling the convergence of miniaturisation, multifunctionality, and cost‑effective mass production. This paper surveys the latest advances in deposition techniques—ranging from magnetron sputtering and chemical vapour deposition to atomic‑layer deposition (ALD) and ink‑jet‑printed sol‑gel processes—and examines how their unique material‑control capabilities translate into performance gains across the sensor spectrum (chemical, physical, and bio‑sensing). By integrating nanoscale thickness control (≤ 10 nm) …

Performance Appraisal of Two-stage On-site Domestic Wastewater Treatment System under Ambient Environment
Abstract: AbstractThe rapid growth in population has rendered the centralized sewerage systems a non-realistic option in sparsely populated areas. Consequently, an on-site wastewater treatment system (OWTS) is a viable alternative and cost-effective solution of sewerage system. Septic tanks with soil absorption systems are a simple mean of onsite treatment of the domestic wastewater. However septic tanks have low treatment efficiency along with several technical and constructional drawbacks. In order to improve …

Optimization of Microbial Cellulose Production by the Newly Isolated Acetobacter sp. DR-1 under Laboratory Conditions
Abstract: Cellulose is the most abundant natural biopolymer on the earth, synthesized by plants, algae and also some species of bacteria. It is also produced by some animals (e.g., tunicates).Cellulose constitutes one of the three principal components present in plant, namely cellulose, hemi-cellulose and lignin. However, the degree of polymerization and crystallinity of bacterial cellulose is considerable high than that of plant cellulose. In microbes, cellulose is normally produced as exo-polysaccharide, …

Isolation, Production and Purification of Antibiotics Isolation from Microbes from Soil
Abstract: A chemical compound acting against life is called antibiotics. The term “antibiotic” literally means “against life”. The term appeared as early as 1928 in the French microbiological literature as antibiosis. The phenomenon of antagonism between living organisms was frequently observed even since 1877, when Pasteur and Joubert noticed that aerobic bacteria antagonized the growth of Bacillus anthracis. However, the world in its present restrictive meaning, “a chemical substance derived from …
