Research on the Static and Dynamic Behavior and Microscopic Mechanisms of Lignosulfonate-Treated Sand

Buildings
Sand, a widely used material in construction, often presents challenges in engineering applications due to its loose granular structure. To address this issue, lignosulfonate (LS), an eco-friendly industrial by-product, is explored as a stabilizing agent

Biomineral‐Inspired Organic/Inorganic Colloidal Liquid‐Crystalline Hybrids for Photoresponsive Adhesion

Advanced Functional Materials, EarlyView.
A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Empirical calibration of Na I D and other absorption lines as tracers of high-redshift neutral outflows

Astronomy & Astrophysics
Recent JWST observations of massive galaxies at z > 2 detect blueshifted absorption in Na I D and other resonant absorption lines, indicative of strong gas outflows in the neutral phase.

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

Advanced Functional Materials, EarlyView.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Programming Nanoscale Reaction Environments via Peptide Localization for Gold Nanoparticle Growth in Liposomal Nanoreactors

Advanced Functional Materials, EarlyView.
The liposome nanoreactor method enables uniform metal nanoparticle synthesis using the interior as a reaction environment. We demonstrate that peptide sequences and lipid compositions act as a functional molecular switch to control reaction environments in liposome nanoreactors.

Dynamic Moduli and Damping Ratios for Monterey No. 0 Sand by Resonant Column Tests

Soils and Foundations, 1989
ABSTRACT The available empirical relationships for maximum dynamic shear modulus (Gmax) and dynamic shear damping (Ds) at low strain amplitudes for sands are reviewed. Based on tests with Monterey No. 0 sand in resonant column device, new relations for Gmax and Ds are proposed.
