Zeolite seed-based mesoporous aluminosilicate material MSU-S is normally synthesized from pure chemicals. In the study, MSU-S material was synthesized using natural resources such as rice husk, and kaolin in Vietnam. Here, a systematic investigation is conducted to find the relationship between the synthesis conditions (aging time, hydrothermal time, hydrothermal temperature, pH environment) and the formation of mesoporous structure, as well as the material properties.

Wastes generated from healthcare practices are a serious problem for humans as well as for the environment. In this study, an attempt was made to use mixed solid medical waste (WPN) which consisted of shredded waste plastic and chopped waste needles for partial replacement of natural fine aggregate (sand) in concrete mixes at 0%, 2%, 4%, 6%, 8% and 10% by weight.

The study will focus on monitoring defects and finding out the nature of these defects. Bulk GaN was irradiated by a 2 MeV electron beam at a fluence of 5×1016 cm2 and studied by deep-level transient spectroscopy (DLTS). After irradiation, a broad peak, including at least two traps, was detected. The trap D1 (EC −0.16 eV) observed from a broad peak is induced during the annealing process below 550K and completely annealed out at 550K after 10 hours.

The objective of the present study is to produce base layer winter active sportswear fabrics using natural and synthetic fibres and their blends which will deliver good comfort properties. Polyester, wool and bamboo fibres were selected for this study. Polyester is the most common fibre used in sportswear, wool is increasingly being used in sportswear and bamboo is a relatively new fibre that offers properties suitable for base layer sportswear. Bamboo is also regarded as a 'green' and eco-sustainable fibre.

Natural resources are being consumed at an alarming rate, and the capacity of resources and technologies to satisfy food demand for the growing population remains uncertain. Since agriculture along with its allied sector, is the largest source of livelihood in India having 70% of rural household depending on agriculture as their primary occupation of which 82 % of farmers are small and marginal (FAO, 2019), the use of non monetory inputs by the poor farmers can be quite the most feasible, eco-friendly and climate smart option to preserve the environment and safeguard the natural resources.
