AI Article Synopsis
Article Abstract
In this work, biodegradable composites from poly(lactic acid) (PLA) and oil palm empty fruit bunch (OPEFB) fiber were prepared by melt blending method. Prior to mixing, the fiber was modified through bleaching treatment using hydrogen peroxide. Bleached fiber composite showed an improvement in mechanical properties as compared to untreated fiber composite due to the enhanced fiber/matrix interfacial adhesion. Interestingly, fiber bleaching treatment also improved the physical appearance of the composite. The study was extended by blending the composites with commercially available masterbatch colorant.

Department of Biology, Indiana University, Bloomington, Indiana, USA.
The bacterial pathogen causes disease in coral species worldwide. The mechanisms of coral colonization, coral microbiome interactions, and virulence factor production are understudied. In other model species, virulence factors like biofilm formation, toxin secretion, and protease production are controlled through a density-dependent communication system called quorum sensing (QS).

Aim: This study evaluated the color stability and surface roughness of two universal-shade compared to two nanohybrid composites after staining and external bleaching with 40% hydrogen peroxide.
Methods: Two universal shade resin-based composites and two nanohybrid composites were tested. Twenty disc-shaped specimens from each material were fabricated and divided into two subgroups: one group was stained and bleached (staining group) and the other received bleaching treatment only (control group).
Sustainable Films Derived from spp. Bark: Improving Properties Through Chemical and Physical Pretreatments.

This study investigates the sustainable use of spp. bark through different chemical (hydrothermal, acid, alkaline, and bleaching) and physical (milling) pretreatments in the production of sustainable films. Valorization of agro-industrial residues and the demand for sustainable materials pose challenges for environmentally responsible solutions.

Background: Caustic substances can inflict severe damage on tissues upon contact. Knowledge about skin damage caused by sodium hypochlorite is quite limited, with only a few reports available in the literature.
Case Report: A 79-year-old female with severe cognitive decline presented with multiple skin ulcerations that were covered by a blackish-greyish eschar and surrounded by a purple erythematous halo.
Factors Affecting Chlorinated Product Formation from Sodium Hypochlorite Bleach and Limonene Reactions in the Gas Phase.
ACS EST Air
September 2024
Office of the Director, Health Effects Laboratory Division, National Institute for Occupational Safety and Health, Morgantown, West Virginia 26505, United States.
During use of sodium hypochlorite bleach, gas-phase hypochlorous acid (HOCl) and chlorine (Cl) are released, which can react with organic compounds present in indoor air. Reactivity between HOCl/Cl and limonene, a common constituent of indoor air, has been observed. The purpose of this study was to characterize the chemical species generated from gas-phase reactions between HOCl/Cl and limonene.
