Facile single-step synthesis of centrifugally spun zein fibers encapsulating housefly oil.

This study investigates centrifugal spinning as a novel approach for producing zein fibers encapsulating housefly oil (HO). Different concentrations of housefly oil (15 %, 30 %, and 45 %; w/w) were evaluated, with rotation speeds ranging from 6000 to 12,000 rpm, to establish optimal production parameters. SEM images revealed continuous fiber formation, with the presence of beads and fiber diameters ranging from 2.

Direct-detection of glyphosate in drinking water a scalable and low-cost laser-induced graphene sensor.

The use of pesticides has significantly increased and proliferated following the technological advancements established by the green revolution, aimed at boosting agricultural productivity. The extensive use of man-made chemicals as fertilizer and pesticides has consequently led to large-scale application, which has led to a number of environmental and human health problems. This study has helped to develop a laser-induced graphene (LIG) sensor for the detection of the most widely used herbicide in the world, glyphosate.

Highly transparent sustainable biogel electrolyte based on cellulose acetate for application in electrochemical devices.

In this study, an easy and low-cost production method for a cellulose acetate-based gel polymer containing lithium perchlorate and propylene carbonate is described, as well as the investigation of its properties for potential use as an electrolyte in electrochemical devices. Cellulose acetate, a biopolymer derived from natural matrix, is colourless and transparent, as confirmed by the UV-Vis spectroscopy, with 85 % transparency in visible spectrum. The gels were prepared and tested at different concentrations and proportions to optimise their properties.

An easy to assemble PDMS/CNTs/PANI flexible supercapacitor with high energy-to-power density.

The fabrication of a flexible supercapacitor with state-of-the-art performance is described, based on a facile and low-cost fabrication method that encompasses aligned carbon nanotube arrays (ACNTA)-polyaniline/polydimethylsiloxane electrodes (ACNTA-PANI/PDMS). The ACNTA were partially embedded in PDMS to ensure excellent adhesion and integration whilst PANI was electrodeposited on its surface to improve energy storage properties. The supercapacitor structure and morphology were investigated by Raman spectroscopy and scanning electron microscopy (SEM), respectively.
