Transforming Fragile Hydrogel Chips Into Standardized Cartridges via Contact Line Pinning for Robust Microfluidics

Small, EarlyView.
Hydrogel‐based microfluidic chips revolutionize drug delivery, tissue engineering, and biosensing, yet face challenges due to fragility and connection difficulty. This study introduces a novel cartridge design that enhances usability through a hydrogel–plastic hybrid design and a contactless connection method.

Unraveling Surface Reconstruction of MOF‐Derived La, P‐Co3O4 for Energy‐Efficient Water and Urea Electrolysis

Small Methods, EarlyView.
Enhanced OER by surface reconstruction: The dopant promotes surface reconstruction and surface oxygen vacancies, which enhance electrochemical activity, charge transfer, and stability, resulting in improved water and urea electrolysis. Abstract Constructing robust electrocatalysts and shedding light on the processes of surface reconstruction is crucial

Fitting the Crab Supernova with a Gamma-Ray Burst

Universe
Here, we reconsider the historical data, assuming a gamma-ray burst (GRB) as its source. A Supernova correlated with the GRB explains well the fading time observed by the ancient Chinese astronomers in the daytime and the nighttime, while the GRB power ...

GRB Duration Distribution Considering the Position of the Fermi

Acta Polytechnica, 2012
The Fermi satellite has a particular motion during its flight which enables it to catch the gamma-ray bursts mostly well. The side-effect of this favourable feature is that the lightcurves of the GBM detectors are stressed by rapidly and extremely ...

EP240801a/XRF 240801B: An X-Ray Flash Detected by the Einstein Probe and the Implications of Its Multiband Afterglow

The Astrophysical Journal Letters
We present multiband observations and analysis of EP240801a, a low-energy, extremely soft gamma-ray burst (GRB) discovered on 2024 August 1 by the Einstein Probe (EP) satellite with a weak contemporaneous signal also detected by the Fermi Gamma-ray Burst

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

A Study of the Spectral Properties of Gamma-Ray Bursts with Main and Second Bursts

The Astrophysical Journal
The origins of the main burst and second burst of gamma-ray bursts (GRBs) and the composition of their jets remain uncertain. To explore this complex subject more thoroughly, we conduct a spectral analysis on 18 GRBs with a main and a second burst ...
