UCST‐Responsive PMEGA: From Solution Behavior to Functional Hydrogel Surfaces

Advanced Materials Interfaces, EarlyView.
PMEGA is used as a versatile water‐based UCST‐responsive platform for engineering microstructured hydrogel coatings via a thiol–ene CLAG approach. From PMEGAs of well‐defined UCST properties, the UV‐based CLAG method provides precise control over film thickness, ranging from nanometers to micrometers, and enables high‐resolution patterning.

Computational Predictions of Velocity Ratio and Ejection Angle on Purge Flow in a Linear Turbine Cascade with Upstream Disturbance

Journal of Applied Fluid Mechanics, 2020
Secondary air bled from the compressor which bypasses the combustion chamber is used to seal the turbine components from incoming hot gas. Interaction of this secondary air or purge flow with the mainstream can alter the flow characteristics of turbine ...

Effect of post-treatment on photocatalytic oxidation activity of (111) oriented NaNbO3 film

APL Materials, 2015
We investigate the impact of post-treatment on photocatalytic oxidation activity of (111) oriented NaNbO3 film prepared by pulse laser deposition. Some impurities such as Na2Nb4O11 and bigger particles appear in the treated samples.

The potential for predicting purge in packaged meat using low field NMR

, 2017
The ability of NMR to predict purge from vacuum-packed pork that was stored for 9 days was investigated. T 2 relaxation was measured at 24 h post mortem ( p.m. ) and again after 9 days of chilled storage. NMR measurements from day 1 p.m.

Microfluidic Gas Purge Valves

, 2009
We present two PDMS-based gas purge valves for general lab-on-a-chip applications. The valves are devised based on a three-layer configuration comprising a top layer for fluid channels, a membrane, and a bottom layer for gas channels.

Thermoplastic Dielectric Coatings for Flexible Electrodynamic Dust Shields: Structural and Functional Performance

Advanced Materials Interfaces, EarlyView.
Thermoplastic attachment is introduced as a scalable surface coating strategy to improve the durability and dielectric reliability of flexible electrodynamic dust shields. By embedding chemically modified reduced graphene oxide (CMrGO) electrodes within thermoplastic laminates, mechanical degradation, abrasion damage, and vacuum‐induced electrical ...

Halide Defect Passivation in CsPbBr3 Nanocrystals Mediated by the Friedel–Crafts Reaction: Enhanced PLQY and Structural Stability Without Bandgap Modulation

Advanced Optical Materials, EarlyView.
Post‐treatment of CsPbBr3 nanocrystals with an AlBr3/CH2Br2 solution does not induce Al3+ substitution at Pb2+ sites. Instead, a Friedel–Crafts reaction generates Br− ions that passivate halide defects, markedly increasing PLQY and improving structural stability without bandgap modulation.

The Influence of Hub Purge Flow Rate on Forced Response in a Low-Pressure Turbine

International Journal of Turbomachinery, Propulsion and Power
We present the results of a computational investigation into the influence of hub purge flow mass flow rate on the forcing amplitudes generated on a low-pressure turbine (LPT) rotor cascade by the upstream stator vane passing (SVP).
