Unique Role of Microstructure of a Bioimplant Zinc Alloy and Protein Content of Simulated Body Fluid in Corrosion and Fracture

Advanced Functional Materials, EarlyView.
BSA addition to physiological solutions enhances resistance of a Zn alloy to stress corrosion cracking (SCC) but reduces its corrosion resistance. Extended surface characterization explains the contrasting influences on corrosion and SCC. Unexpectedly, the alloy suffers transgranular SCC (TGSCC), despite extensive grain boundary precipitation. Thorough

Amine-Functionalized MIL-101 Monoliths for CO₂ Removal from Enclosed Environments

, 2019
Amine-functionalized metal–organic frameworks (MOFs) are facile adsorbents for CO2 removal from enclosed environments. In this study, we prepared polyethylenimine (PEI) and tetraethylenepentamine (TEPA) impregnated MOF-monoliths using a 3D printing ...

Activation studies of the β-carbonic anhydrases from Malassezia restricta with amines and amino acids

Journal of Enzyme Inhibition and Medicinal Chemistry, 2020
The β-carbonic anhydrase (CA, EC 4.2.1.1) from the genome of the opportunistic pathogen Malassezia restricta (MreCA), which was recently cloned and characterised, herein has been investigated for enzymatic activation by a panel of amines and amino acids.

High‐Efficiency Quantum Defect Generation in Carbon Nanotubes via Oxygen‐Free Photochemistry

Advanced Functional Materials, EarlyView.
We show that oxygen plays an important role in quantum defect formation in carbon nanotubes and identify reaction conditions to create a range of different quantum defects for photonics and biosensing. ABSTRACT Single‐walled carbon nanotubes (SWCNTs) offer potential for a wide range of applications from optoelectronic devices to biomedical diagnostics.

Turn on Fluorescent Probes for Selective Targeting of Aldehydes

Chemosensors, 2016
Two different classes of fluorescent dyes were prepared as a turn off/on sensor system for aldehydes. Amino derivatives of a boron dipyrromethene (BDP) fluorophore and a xanthene-derived fluorophore (rosamine) were prepared.

Decoupling Li+ Transport in Self‐Healing Polymer Dual‐Salt Electrolytes for Room Temperature Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
A self‐healable polymer matrix, crosslinked via dynamic imine bonds, is synergistically coupled with a LiPF6–LiDFOB dual‐salt system to decouple Li+ from the polymer matrix, enabling fast Li+ transport. This strategy offers an effective pathway toward high‐performance, next‐generation gel‐polymer‐based Li‐metal batteries.

Amine-Phosphate Specific Interactions within Nanochannels: Binding Behavior and Nanoconfinement Effects

, 2019
In the last years, the ionic conductance behavior of solid-state nanochannels (SSN) has been extensively studied with both basic and applied purposes. In particular, the interactions between confined groups and dissolved species have been widely used for
