Surface Roughness and Its Role in Flotation Behavior, Wettability, and Bubble–Particle Interactions: A Systematic Review

Applied Sciences
Surface roughness refers to the micron- or nanometer-scale irregularities (bumps and grooves) on material surfaces, and it varies greatly as particles are refined, affecting their flotation behavior, wettability, and bubble–particle interactions. In this

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

Advanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Bistable Wetting States on a Smooth Surface

Advanced Materials Interfaces
Droplets on a non‐textured surface typically exhibit a monostable wetting state, as represented by Young state. Here, we show that droplets can exhibit bistability without surface texture by tuning molecular interactions.

Uptake of Sulfadiazine Sulfonamide from Water by Clinoptilolite

Applied and Environmental Soil Science, 2013
The interactions between sulfadiazine (SDZ), a sulfonamide antibiotic, and clinoptilolite, a hydrophilic zeolite, were investigated under batch experimental conditions. The uptake of SDZ on the zeolite followed a linear sorption isotherm under neutral pH

Water Organization and Hydration‐Dependent Hydroxide Transport in Anion Exchange Membranes (AEM)

Advanced Functional Materials, EarlyView.
Hydroxide transport in anion exchange membranes is governed by the organization of water within the polymer rather than by hydration alone. A hydration‐window framework is presented to unify transport, swelling, and mechanical stability, providing guidance for designing durable membranes for fuel cells and other hydroxide‐based electrochemical ...

Identification of the fractions responsible for plant root elongation-promoting and antioxidant activities of humic product extracted from composted wood thinnings

Chemical and Biological Technologies in Agriculture
Background HS-2®Pro, a humic product, is produced from composted thinnings of coniferous trees and is commercially available as a biostimulant. In this study, it was fractionated into humic acid (HA), hydrophobic fulvic acid (FA), hydrophilic FA, and ...

Reversible Tuning of Multiple Molecular Kinking for Stem Cell Regulation In Vivo

Advanced Functional Materials, EarlyView.
In this work, we introduce the novel concept of background component‐free “multiple kinks” material platform composed solely of liganded multiple kink‐bearing molecules as a strategy for dynamic biomaterial design. Tri‐kink molecules enable effective near‐infrared light‐triggered ligand masking and visible light‐triggered ligand exposure, thereby ...

Role of long- and short-range hydrophobic, hydrophilic and charged residues contact network in protein’s structural organization

BMC Bioinformatics, 2012
Background The three-dimensional structure of a protein can be described as a graph where nodes represent residues and the strength of non-covalent interactions between them are edges.
