Metal‐Free Ternary‐Composite Aerogel Based on Graphitic Carbon Nitride, Graphene Oxide, and β‐Cyclodextrin for Synergistic Adsorption and Photodegradation of Organic Dyes

open access: yesSmall, EarlyView.
A novel metal‐free g‐C3N4/GO/β‐CD aerogel exhibits a high adsorption capacity of 653.2 mg/g for RhB. The synergistic adsorption‐degradation effect of the aerogel enables the complete elimination of organic dyes. Fixed‐bed and recyclability tests demonstrate its potential for continuous industrial wastewater treatment.

Molecularly Mediated Assembly of Metal Nanoparticles With Multifunctional Interfaces for Selective Detection of Small Gas Molecules

open access: yesSmall, EarlyView.
This work demonstrates a conceptual framework of three types of cooperative interaction pathways in molecularly assembled nanoparticle chemiresistors. Their relative contributions depend on nanoparticle composition, linker chemistry, film architecture, and analyte identity, modulating the effective tunneling barrier (Φ), interparticle spacing (d), and ...

Metal/Si Nanowire Arrays for Hot Electron Catalysis

open access: yesSmall, EarlyView.
Silicon nanowire arrays enhance plasmon‐driven catalysis by strengthening light–matter interactions on Au and Ag nanostructured coatings. Hotspot accessibility, rather than near‐field intensity alone, governs photocatalytic performance, while Ag nanoshells exhibit superior activity. The work establishes high‐surface‐area Si nanowire arrays as versatile

Reconfiguration of Localized Ruthenium Surface via Incorporating Single Platinum Atoms for Favorable Hydrogen Oxidation Catalysis

open access: yesSmall, EarlyView.
The introduction of a Pt single atom changes the Ru surface structure and results in the reconstruction of the active sites for hydrogen and CO oxidation catalysis. With a Pt loading of only 1 wt.%, RuPtSA exhibited superior HOR activity and resistance to impurities compared to commercial Pt catalysts in both acid and alkaline electrolytes.

Fractionation‐Free Protein Corona Quantification Through Synchrotron‐Based Small‐Angle X‐ray Scattering

open access: yesSmall Methods, EarlyView.
A fractionation‐free SAXS approach quantifies protein corona formation on silica nanoparticles under native conditions. By deconvoluting scattering from free and bound proteins, adsorbed mass is directly determined in simple and complex media. The method resolves adsorption regimes and thermodynamics, establishing non‐invasive, in situ characterization

Study of the influence of ionizing radiation on the activity of the neurotoxin Vipoxin in a model monolayer system at the water/air interface

open access: yesResults in Surfaces and Interfaces
The main components of the cell membrane are phospholipids, and the enzymes that hydrolyze them for the purposes of many important physiological functions are the phospholipases whose properties strongly depend on the phospholipids’ structural ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
