Engineered surface strategies to manage dental implant‐related infections
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Analysis of a Mars-stationary orbiting microwave power transmission system [PDF]
To determine the feasibility of providing efficient RF power transmission from a Mars-stationary orbit to the surface of the planet, an assessment was made focussing on RF propagation in the 2.45- to 300-GHz range.

This study investigates the impact of calcium on the performance of a large‐scale internal circulation (IC) reactor treating calcium‐rich dairy wastewater. Excessive calcium concentrations (400‐600 mg L−1) resulted in calcification of the anaerobic sludge, reactor walls, and pipes, suggesting a 17% and 25% reduction in biogas and methane production ...

Homogeneous reactions of hydrocarbons, silane, and chlorosilanes in radiofrequency plasmas at low pressures [PDF]
The ion-molecule and radical-molecule mechanisms are responsible for the dissociation of hydrocarbon, silane, and chlorosilane monomers and the formation of polymerized species, respectively, in an RF plasma discharge. In a plasma containing a mixture of

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Glycerol carbonate formation from glycerol and dimethyl carbonate using lithium‐based catalysts
Abstract Excess glycerol from biodiesel production can be sustainably converted into value‐added products like glycerol carbonate, for its use in polymers, solvents, and as ecofriendly alternative as green chemical in various chemical industries. This study aims to synthesize a catalyst optimized for the glycerol and dimethyl carbonate (DMC) conversion

Unveiling the Anticancer Properties of New Synthesized Alkoxy‐ and Methyl Thio‐Chalcone Derivatives
ABSTRACT Breast and cervical cancers are a serious problem and the leading cause of death in women in this decade. Chalcone is a promising compound with great potential for anticancer use. In this work, we synthesized six chalcone derivatives with alkoxy‐ and methylthio‐substituents through Claisen–Schmidt condensation at room temperature.
