The optical properties of metal nanoparticles have long been of interest in physical chemistry, starting with Faraday's investigations of colloidal gold in the middle 1800s. More recently, new lithographic techniques as ...

This study investigates how four nano-additives, namely graphene, amine-functionalized graphene, hexagonal boron nitride (hBN), and multi-walled carbon nanotubes, affect the properties of polylactic acid (PLA) used in ma...

Este trabalho avalia as principais propriedades do carvão de Manilkara amazonica (maçaranduba), Lecythis pisonis (sapucaia) e Piptadenia suaveolens (timborana), carbonizadas em sete e dez dias. O carvão foi produzido ...

To elucidate the influence of bi-substitution on the structural and hyperfine properties of goetites, two series of (Al,Co)- and (Mn,Co)-substituted goethites were synthesized in alkaline media by aging several ferrihydr...

Residues discarded at cherry fruit harvesting were extracted with ethanol from ‘Chelan’, ‘Brooks’ and ‘Sunburst’ varieties to obtain cherry fibers constituted by the cell wall polysaccharides, applicable as f...

Hydrogen is widely recognized as a clean and sustainable energy carrier, driving the urgent need for safe and efficient solid-state storage materials. In this study, the structural, thermodynamic, electronic, optical, an...

Optical imaging is a powerful tool for investigating the structure and function of tissues. Tissue optical imaging technologies are generally discussed under two broad regimes: microscopic and macroscopic, while the latt...

Graphene hosts massless Dirac fermions owing to its linear electronic band structure. This distinctive feature underpins its extraordinary electronic properties, correlating to strong light–matter interactions on an ex...

PLA coating on Kraft paper is very promising systems for food packaging, and has potential environmental advantages over conventional synthetic paper coatings. This work was focused on: (i) analyzing the physicochemical,...

Artificial saliva (AS) is an aqueous solution designed to mimic the properties of natural saliva and is widely used in various in vitro studies. This investigation aimed to identify the most frequently selected AS compos...

Post-processing evolution of the functional properties of soybean protein concentrate (SPC) films, plasticized with varying levels of glycerol and processed by compression molding, was examined over a period of 90 days. ...

Influence of weight polymer variation towards sodium fluoride patch physical properties. Fluoride has been proven as a material for strengthen teeth. Many fluoride modalities are available nowadays, and the recent is sod...

A novel fibre treatment recently proposed in the literature was optimised in the case of woven jute fabric/vinylester laminates to obtain the best tensile properties. It consists on an alkali treatment superimposed to bi...

Due to their attractive optical properties, 2D MXenes have garnered interest in nanophotonic and optoelectronic applications. However, tuning their properties typically requires the iterative synthesis of MXenes with a s...

Abstract Insects have long been consumed by humans as a supplemental protein source, and interest in entomophagy has rapidly increased in recent years as a potential sustainable resource in the face of environmental chal...

"Material Jetting technology has proven to be very useful in the manufacture of parts with a variety of shapes, consistencies, textures, transparencies and colours, and a great diversity of mechanical properties can be a...

Abstract Environmental hazards of micro- and nanoplastics (MNPs) and associated chemicals have been investigated for more than a decade. However, the field of human MNPs health risk assessment is still confronted by many...

Two metallocene EPDMs with the same weight fraction of ethylene but differing in diene content were crosslinked, either by dicumyl peroxide (DCP) or β-radiation. The effect of different diene and propylene content on th...

Abstract This study aimed to compare the similarities, physicochemical properties, and muscle fiber characteristics of porcine skeletal muscles. Fourteen types of muscles were collected from nine pig carcasses at 24 h po...

What makes three dimensional semiconductor quantum nanostructures so attractive is the possibility to tune their electronic properties by careful design of their size and composition. These parameters set the confinement...

This research examines the determinants of agricultural land prices in the Mendoza River Basin, with emphasis on the marginal contribution of irrigation water as a strategic resource in an arid context. An original geore...

Background: Natural biopolymeric matrices for developing dressings have been extensively studied, as they may exhibit beneficial properties for wound healing. Gelatin possesses promising structural and physicochemical pr...
