The use of energy-saving materials is an effective strategy for decreasing energy consumption and carbon emission. Wood is a type of biomass material with a natural hierarchical structure, which results in its high thermal insulation. It has been widely used in construction. However, developing wood-based materials without flammability and dimensional...

Chilean researchers explore novel approach to eco-friendly food packaging Polylactic acid (PLA) is a polymer made from renewable biomass; typically, fermented plant starches, such as corn, sugarcane, cassava, or sugar beet. In use, it exhibits similar mechanical and physical properties to some petroleum-derived polymers, but it is biodegradable – under...

In polymer systems, induction heating (IH) is the physical outcome that results from the exposure of selected polymer composites embedding electrically-conductive and/or ferromagnetic fillers to an alternating electromagnetic field (frequency range: from kHz to MHz). The interaction of the applied electromagnetic field with the material accounts for the creation of...

In order to promote the research of green energy in the situation of increasingly serious environmental pollution, dielectric ceramic energy storage materials, which have the advantages of an extremely fast charge and discharge cycle, high durability, and have a broad use in new energy vehicles and pulse power, are being...

The use of biodegradable polyesters derived from green sources and their combination with natural abundantly layered aluminosilicate clay, e.g., natural montmorillonite, meets the requirements for the development of new sustainable, disposable, and biodegradable organic dye sorbent materials. In this regard, novel electrospun composite fibers, based on poly β-hydroxybutyrate (PHB) and...

A space solar power prototype that was launched into orbit in January is operational and has demonstrated its ability to wirelessly transmit power in space and to beam detectable power to Earth for the first time.Wireless power transfer was demonstrated by MAPLE, one of three key technologies being tested by...

Numerical simulations of 2D phase field models show that deformable suspensions display the hallmark of yield-stress fluids....

Background and Objective: This study aimed to compare the surface finish of milled leucite-reinforced ceramics polished with ceramic and composite polishing systems based on the manufacturers’ recommendations. Materials and Methods: Sixty subtractive computer-aided manufactured (s-CAM) leucite-reinforced glass-ceramic specimens (IPS-Empress-CAD) were assigned into six groups: no polishing, a ceramic polishing kit,...

Carbon dots-based composite hydrogel selectively eliminates bacteria and promotes osteogenesis for infectious bone repair....

We develop a general approach for the computation of the effective properties of nonlinear viscoelastic composites. For this purpose, we employ the asymptotic homogenisation technique to decouple the equilibrium equation into a set of local problems. The theoretical framework is then specialised to the case of a strain energy density...

Huntsman, owner of the Araldite brand, has developed polyurethane, epoxy and carbon nanotube materials for vehicle battery construction and protection. For underbody battery protection, Rimline (=polyurethane) wet compression moulding material are low-viscosity liquid resins for low-pressure moulding of composites with a high fibre volume fraction – formulated for high-pressure mix...

A biocompatible metal–organic framework MIL-100(Fe) loaded with the active compounds of tea tree essential oil was used to produce composite films based on κ-carrageenan and hydroxypropyl methylcellulose with the uniform distribution of the particles of this filler. The composite films featured great UV-blocking properties, good water vapor permeability, and modest...
