Photothermal Macroporous Lignin Cryogels for Off‐Grid, Continuous Atmospheric Water Collection via Interlayer Heat Recovery

Advanced Functional Materials, EarlyView.
Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.

Preparation of Tin-doped Carbon Hollow Spheres and Their Electrocatalytic activity in Water Electrolysis

International Journal of Electrochemical Science, 2013
Hollow carbon sphere electrocatalysts were synthesized by combining the hydrothermal and intermittent microwave heating (IMH) technique. The addition of P123 as surfactant has created huge amount of pores, resulted in the ultrahigh surface area of 1300 ...

Selective Separation of the Rare Earth Elements Dysprosium and Neodymium via Tailoring Nanocellulose Chemical Structure

Advanced Functional Materials, EarlyView.
Dicarboxylate‐modified anionic hairy cellulose nanocrystals exhibit a high selectivity for dysprosium(III) over neodymium(III). This selectivity arises from disordered dicarboxylate cellulose “hairs” that enable cooperative ionic coordination, hydrogen bonding, and strain‐induced conformational shrinkage.

The interaction between flow-induced vibration mechanisms of a square cylinder with varying angles of attack [PDF]

, 2012
This study examines the influence of angle of attack of a square section cylinder on the cylinder’s flow-induced vibration, where the direction of the vibration is transverse to the oncoming flow.

Effects of intermittently applied cyclic loading on proteoglycan metabolism and swelling behaviour of articular cartilage explants

Osteoarthritis and Cartilage, 1999
The aim of this study was to evaluate the effect of tissue load, frequency and load duration on the biosynthesis and release of proteoglycans (PGs) as well as on the swelling behaviour of cultured mature bovine articular cartilage superimposed with intermittent loads.Cyclic compressive pressure was introduced for 1, 3 or 6 days using a sinusoidal ...

Dual‐Site Ru Single‐Atoms and RuP Nanoclusters on N, P, and B Co‐Doped Porous Carbon for Efficient Alkaline HER and AEM Water Electrolysis

Advanced Functional Materials, EarlyView.
Ru single atoms and RuP nanoclusters are co‐anchored in N, P, and B co‐doped porous carbon nanospheres via in situ carbonization/phosphidation of a boronate polymer precursor. RuP activates water, while nearby Ru single atoms accelerate H2 formation through H* transfer. The catalyst delivers low overpotential and high durability in alkaline HER and AEM

Electrocatalytic Reduction of CO2 to Ethylene: Catalyst Design and Synchrotron‐Based Characterizations

Advanced Functional Materials, EarlyView.
This review evaluates strategies for electrochemical CO2 reduction to ethylene, focusing on copper‐based catalyst design and microenvironment modulation to achieve industrial‐grade performance. By leveraging operando synchrotron‐based characterizations, we provide a multiscale understanding of dynamic structural transformations and key reaction ...

Photo‐Controlled Antibacterial Drug Release From DASA‐Coated Silica Particles for Improved Treatment of Wound Infections

Advanced Functional Materials, EarlyView.
Synthesis and characterization of light‐responsive donor–acceptor Stenhouse adducts (DASA)‐coated chlorhexidine‐loaded silica nanoparticles. Such a controllable drug‐delivery system enables the release of the antimicrobial drug on demand and in consecutive cycles, thereby maintaining the concentration within the therapeutic window.

Shear behaviors of intermittent joints subjected to shearing cycles under constant normal stiffness conditions: Effects of loading parameters

Journal of Rock Mechanics and Geotechnical Engineering
A conceptual model of intermittent joints is introduced to the cyclic shear test in the laboratory to explore the effects of loading parameters on its shear behavior under cyclic shear loading. The results show that the loading parameters (initial normal
