Orthogonal Staggered Alignment of Molecular Chains in Aramid Whiskers: A Game‐Changer for Sustainable, High‐Performance Composites

Macromolecular Rapid Communications, EarlyView.
Poly(p‐benzamide) whiskers with orthogonal chain alignment form prismatic single crystals, enabling uniform dispersion and high crystallinity. This architecture enhances composite thermal stability, modulus, and dimensional integrity, offering a sustainable, lightweight alternative to inorganic fillers and redefining polymer crystallography through ...

Recycled powder as filler admixture in cementitious systems : production and characterization [PDF]

, 2016
In concrete production, aggregate represents almost 75% of the materials used. The exploitation of natural sources for this purpose also causes an environmental impact, while deposition of wastes from construction industry pollutes soil and water.

Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

Macromolecular Reaction Engineering, EarlyView.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.

Green Synthesis of ZnO Nanoparticles From Spirulina platensis: Antimicrobial and Cytotoxic Evaluation With Molecular Docking Studies

ChemistryOpen, EarlyView.
Algal‐extract‐derived ZnO nanoparticles show shape anisotropy and are bio capped by phytochemicals. These green‐synthesized NPs strongly inhibit S. aureus and K. pneumoniae biofilms. Molecular docking suggests stable binding of surface biomolecules to microbial targets, highlighting synergistic antibacterial mechanisms.

Using Lignin and Spent Coffee Grounds as Bio‐Additives in 3D‐Printable Poly Lactic Acid/Multi‐Walled Carbon Nanotube Composites for Advanced Electronic Applications

Polymer Composites, EarlyView.
Bio‐based additives derived from lignin and spent coffee grounds (SCG) are used to enhance MWCNT dispersion in PLA composites, enabling improved electrical conductivity and reliable in material extruded strain‐gauge sensors. ABSTRACT In this work, three bio‐based additives, lignin, spent coffee grounds (SCG), and oil extracted from SCG (Ox‐SCG) were ...
