Study of conformational changes and protein aggregation of bovine serum albumin in presence of Sb(III) and Sb(V).

PLoS ONE, 2017
Antimony is a metalloid that affects biological functions in humans due to a mechanism still not understood. There is no doubt that the toxicity and physicochemical properties of Sb are strongly related with its chemical state.

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Multi-environment and multi-parameter screening of stability and coating efficiency of gold nanoparticle bioconjugates in application media

Scientific Reports
Gold nanoparticles (AuNPs) and their biocompatible conjugates find wide use as transducers in (bio)sensors and as Nano-pharmaceutics. The study of the interaction between AuNPs and proteins in representative application media helps to better understand ...

Characterisation of chitosan molecular weight distribution by multi-detection asymmetric flow-field flow fractionation (AF4) and SEC.

International Journal of Biological Macromolecules, 2019
A new method for the molecular weight (MW) determination of chitosans by asymmetric flow field flow fractionation (AF-FFF or AF4) coupled with multi-angle light scattering (MALS) and differential refractive index (RI) detectors is proposed.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.
