A Promising MM–Fe–Al–Ga–B Permanent Material with Substantially Boosted Magnetic Performance

Advanced Science, EarlyView.
A facile two‐step strategy, Al‐doping toward high‐(BH)max followed by Nd/Pr‐based grain boundary diffusion processing toward high‐Hcj, endows the microcrystalline MM–Fe–Al–Ga–B magnet with substantially boosted magnetic performance [(BH)max = 28.02 MGOe, Hcj = 10.14 kOe].

Water‐Enhanced Multicolor Electrochromism in Nickel‐Catecholate MOFs

Advanced Science, EarlyView.
This work reports a new multicolor electrochromic behavior in conducting nickel‐catecholate (Ni‐CAT‐1) MOFs, exhibiting transitions from green to blue and then to purple. The coloring mechanism involves the interconversion of C─O, C─O•, and C = O bonds.

Smart Organic–Inorganic Copolymer Nanoparticles Distinguish Between Microglia and Cancer Cells for Synergistic Immunotherapy in Glioma

Advanced Science, EarlyView.
The tumor microenvironment‐responsive nanoagonists are developed using an organic–inorganic copolymer composed of the polymer (PC6AB) and manganous phosphate ionic oligomers (MnP). PC6AB with membranolytic activity selectively interacts with tumor cell membranes to induce immunogenic cell death, while MnP activates the STING pathway in immune cells ...

Releasing 8.0 wt.% H2 from the LiBH4−2LiNH2 Composite within 5 Min under Light Illumination

Advanced Science, EarlyView.
The N−H bond in the [NH2]− ion group is significantly weakened by the non‐thermal effect of UV light, leading to a 60‐fold increase in dehydrogenation rate at the same temperature. As a result, over 8.0 wt.% H2 is released within 5 min. Abstract The absence of safe and efficient hydrogen storage technologies is the major bottleneck for widespread ...

Vermicular Eutectic Multi‐Principal Element Alloy with Exceptional Strength and Ductility

Advanced Science, EarlyView.
Eutectic multi‐principal element alloys (EMPEAs) typically exhibit rod‐like or lamellar microstructures, constraining further mechanical improvements. This study introduces a novel (AlCrFe2)65Ni35 EMPEA with a unique vermicular microstructure, achieving unprecedented strength‐ductility synergy.

Understanding Glass through Differential Scanning Calorimetry

Chemical Reviews, 2019
Differential scanning calorimetry (DSC) is a powerful tool to address some of the most challenging issues in glass science and technology, such as the nonequilibrium nature of the glassy state and the detailed thermodynamics and kinetics of glass-forming systems during glass transition, relaxation, rejuvenation, polyamorphic transition, and ...

Polymorphism by differential scanning calorimetry

Thermochimica Acta, 1994
Abstract After a basic introduction to polymorphism the most useful methods of detection of polymorphism are cited. A selection of typical DSC curves illustrates monotropic and enantiotropic solid—solid transition, allotropy, metastable—stable transition through the liquid state, pseudopolymorphic transition and mesophase transition. In addition, the

Modulated differential scanning calorimetry

Thermochimica Acta, 1994
Abstract Modulated differential scanning calorimetry (MDSC) is a recently developed extension of DSC that adds a new dimension to the conventional approach. The usually linear temperature programme is modulated by a small perturbation, in this case a sine wave, and a mathematical treatment is applied to the resultant data to deconvolute the sample ...
