Due to the increased predictability of current bonding procedures and the improved properties of today's composite materials, large Class II and cuspal build-up direct composite resin restorations are routinely performed. Biological considerations and the stress associated with polymerization shrinkage are key factors that need to be considered during the treatment planning phase. This article demonstrates a combination of concepts and techniques to reduce the stress associated with polymerization shrinkage in large restorations, thus potentially improving the longevity of the restoration.

Magnetorheological (MR) fluids can be utilized in one of the fundamental operating modes of which the gradient pinch mode has been the least explored. In this unique mode non-uniform magnetic field distributions are taken advantage of to develop a so-called Venturi-like contraction in MR fluids. By adequately directing magnetic flux the material can be made solidified in the regions near the flow channel wall, thus creating a passage in the middle of the channel for the fluid to pass through.

Iron-dependent denitrification has been substantially investigated worldwide due to the advantages of low cost, high efficiency, and synchronized phosphorous removal. However, differences in nitrogen metabolism processes with different iron-based materials as electron donors have not been systematically studied. This study investigated the efficacy of nitrogen and phosphate removal using various iron-based materials as electron donors.

This study focuses on enhancing solar energy capture efficiency by introducing innovative hybrid nanofluids for use in solar thermal collectors, whose performance largely depends on the absorption properties of the working fluid. The newly developed hybrid nanofluids, MXene/NH2-UiO66 (Zr) (noted as MX/UO66) and MXene/MIL-88B (Fe) (noted as MX/ML88), were synthesized using an in-situ solvothermal method, combining annealed Ti3C2Tx MXenes with water-stable metal-organic frameworks (MOFs). These nanofluids achieved high efficiency at low concentrations, providing both economic and performance benefits.

Novel functional materials possessing the capability to attenuate electromagnetic energy are being increasingly incorporated into home decor as concerns over excessive electromagnetic radiation pollution continue to grow. The properties of magnetism and dielectricity in the flexible peanut shell/CoFeO/reduced graphene oxide/polyvinyl alcohol (PS/CF/(RGO)/PVA) nanocomposites can be finely tuned by adjusting the amount of RGO in the mixture. An examination of the composite's absorption capabilities revealed a direct link between higher RGO content and enhanced absorption.

Modifying ZnO nanorods with graphene oxide (GO) is crucial for enhancing photocatalytic degradation by boosting the concentration of reactive oxygen species (ROS) in the reaction medium. In this study, we present a straightforward chemical synthesis of ZnO nanorods embedded on GO, forming a novel nanocomposite, GOZ. This composite serves as an efficient photocatalyst for the sunlight-driven degradation of methylene blue (MB) and ciprofloxacin (CIP).
