This study demonstrates that a keratin-based bioplastic derived from waste chicken feathers effectively inhibits mild steel corrosion in 0.1 M HCl through concentration- and temperature-dependent adsorption, achieving a maximum efficiency of 54% at 323 K while functioning as a mixed-type inhibitor.
This study presents a dynamically stabilized crystalline–amorphous hybrid IrO₂ catalyst that overcomes the traditional activity–stability trade-off in acidic water electrolysis by confining conductive crystalline nanodomains within a porous amorphous matrix, thereby enabling ultra-durable operation with high current densities and negligible degradation over 3400 hours.
This paper demonstrates that Cryo-Soft X-ray Tomography (cryo-SXT) is a promising, non-destructive technique for characterizing beam-sensitive nanomaterials, such as rapidly synthesized magnetite and zerovalent iron nanoparticles, by providing high-resolution 3D imaging that overcomes the limitations of conventional methods.
This study demonstrates that optimizing Sc/Zr and Zn/Zr modifications in laser-directed energy deposited Al–7Mg alloys effectively refines grain structure to achieve a superior balance of high tensile strength and corrosion resistance, offering a cost-effective strategy for reducing reliance on scandium.
This study employs a comprehensive computational approach, including DFT, molecular docking, and dynamics simulations, to identify the donepezil derivative MH-4 as a promising, stable, and safe acetylcholinesterase inhibitor with enhanced electronic properties and favorable pharmacokinetics for Alzheimer's disease treatment.
This paper reports the scalable two-step synthesis of trans-A2B2 meso-5-nitrothien-2-yl porphyrins and demonstrates through spectroscopic and electrochemical analyses that the near-coplanar thienyl substituents induce strong electronic communication with the porphyrin core, evidenced by anodic redox shifts and bathochromic absorption changes.
This study reveals that the complex lattice distortions in Sr7-xAxMn4O15 (A = Ca, Ba) arise from the coupling between anisotropic site substitutions and acoustic instabilities mediated by rigid unit modes, offering a new framework for understanding how chemical disorder drives structural responses in functional materials.
This study analyzed 17 popular disposable e-cigarettes and found that while sweeteners like neotame and coolants like WS-23 are present in the e-liquids, a significant portion (ranging from 26% to 88%) of these compounds, along with nicotine and menthol, is carried over into the inhaled aerosol, highlighting substantial user exposure to these additives.
This study reports the optimized microbial synthesis of reduced graphene oxide nanosheets using *Proteus mirabilis* MT378377 under specific conditions of temperature, pH, and additives, revealing that while the resulting nanomaterials possess suitable characteristics for drug delivery, they exhibit lower antibacterial activity against multidrug-resistant bacteria compared to graphene oxide.
This study presents a synergistically dual-modified polyurethane sponge (M/Si-6@PU) coated with MIL-53(Al) and dimethylsilicone oil that achieves superhydrophobicity, rapid oil absorption, and exceptional cyclic stability for the efficient separation of oily sludge thermal washing wastewater.
