PVP-based hydrogels: Synthesis, properties and applications

, 2018
Hydrogels are three dimensionally crosslinked polymeric network which can retain a huge amount of water but do not dissolve in water. Polyvinylpyrrolidone (PVP) is a synthetic polymer with good biocompatibility and transparency and with the action of ...

Reaction‐Driven Self‐Organization of Nanocrystals by Kinetic Control of Inhomogeneous Photopolymerization

Advanced Science, EarlyView.
Patterned light reorganizes initially uniform CsPbBr3 perovskite quantum dots into well‐defined structures during photopolymerization. Using a digital micromirror device, we show that this reaction‐driven self‐organization is governed by a competition between chemical‐potential‐driven migration and kinetic arrest caused by rapid solidification ...

A Neutrophil Membrane‐Encapsulated Pd/hCeO2 Nanoformulation for Alleviating Age‐Dependent Perioperative Neurocognitive Disorders

Advanced Science, EarlyView.
This study reports a neutrophil membrane‐encapsulated Pd/hCeO2 nanozyme (PCN) for targeted treatment of perioperative neurocognitive disorders (PND) in aged mice. PCN inhibits glycolysis‐driven microglial activation and neuroinflammation, improves mitochondrial respiration, and maintains blood‐brain barrier integrity and synaptic function, ultimately ...

Robust, Breathable and Stretchable Liquid Metal Composite Nanofibre for Physiological Electrical Signal Monitoring

Advanced Science, EarlyView.
A conductive TPU/liquid‐metal nanofibrous film is fabricated via ultrasonic dispersion, electrospinning, and mold imprinting. The film is breathable, stretchable, deformation‐stable, and provides electromagnetic shielding. n‐Butanol encapsulation mitigates liquid‐metal surface tension and improves biocompatibility. Stable ECG, EOG, EEG, and EMG signals

Electronic‐State Programming of Ultrasmall CeO2 Switches H2O2 Activation From Radical to Bio‐Inspired Nonradical 1O2 Generation for Combating Antibiotic Resistance

Advanced Science, EarlyView.
A scalable synthesis of carbon‐supported ultrasmall CeO2 nanoparticles with precisely tunable Ce electron density is reported. Electron‐lean Ce sites activate H2O2 exclusively via a nonradical pathway, enabling efficient HOBr and 1O2 production analogous to bromoperoxidase for contaminant and antibiotic resistance removal.

Facile One‐Pot Solvothermal Synthesis of Bi2Te3 Nanoplate/Te Nanorod Composites with High Seebeck Coefficients for Flexible Film‐Based Thermoelectric Generators

Advanced Electronic Materials, EarlyView.
A one‐pot solvothermal reaction yields Bi2Te3 nanoplate/Te nanorod composites, in which the antimony precursor regulates crystallite size without lattice incorporation. Drop‐cast flexible films reach Seebeck coefficients of −127 and 323 µV K−1 at 393 K, and a flexible thermoelectric generator produces 6.2 mV at a temperature difference of 5.6 K ...
