Plastic production has become a global concern, including in Bangladesh. Among all types of plastic products, single-use is considered treacherous and the most responsible for damaging natural environment. To replace plastics on daily usage basis, entrepreneurs Bangladesh have reiterated some initiatives to manufacture promote alternatives. This study aims assess market potential, existing chal...

Humic substances (HS) are macromolecular organic materials ubiquitous in both aquatic and terrestrial systems, effective electron shuttling compounds providing macro- microelements organochelate form, play an important role determining the mobility bioavailability of organic/inorganic nutrients mineral fertilizers [...]

Magnesium oxide nanoparticles were synthesized using Arabic gum as a biotemplate andmagnesium nitrate as the magnesium source by the sol-gel method. This method has manyadvantages such as nontoxic, economic viability, ease to scale up, less time consuming andenvironmental friendly approach for the synthesis of MgO nanoparticles without using anyorganic chemicals. Nanoparticles were characterize...

In the global economy environment, industrial products need to be re-designed in order to meet the requirements of the global market. Changes regarding products are implemented on two levels, with one focusing on their competitiveness and the other on environment protection. There is an interaction between both levels as competitive products are mostly those products that have been re-designed ...

Objective(s): The development of reliable and ecofriendly process for the synthesis of nano-metals is an important aspect in the field of nanotechnology. Nano-metals are a special group of materials with broad area of applications. Materials and Methods: In this study, extracellular synthesis of silver nanoparticles (SNPs) performed by use of the gram positive soil Streptomycetes. Streptomycete...

Parents looking to foster more energy sufficient behaviours in their children struggle to have their child maintain these behaviours unsupervised. Our research indicates that in order for the child to maintain these behaviours, s/he must perceive him/herself as an eco conscious individual. We propose that increasing a child’s ability to firstly recognise eco-friendly behaviours and secondly, re...

A new, facile, cost effective, and eco-friendly protocol is reported for the synthesis of 2,3-dihydroquinazoline-4-(1H)-ones exploring tannic acid as a novel, inexpensive, andbiodegradable catalyst. A variety of dihydroquinazolins were prepared from aromatic aldehydesand anthranilamide using catalytic amount of tannic acid under solvent free conditions.Operational simplicity, high yield, and hi...

Ammonium monovanadate (NH4VO3) has been devoted as an efficient, commercially available, eco-friendly and reusable catalyst for the synthesis of bis(indolyl)methanes (BIMs), oxindole derivatives and also Michael adducts of indoles at 50 °C under solvent-free conditions. The reusability of this solid acid catalyst in addition with its selectivity has also been examined.
