High‐Throughput Screening for Accelerated Oxide Glass Discovery

open access: yesAdvanced Science, EarlyView.
A high‐throughput screening platform is presented that allows for accelerating laboratory glass synthesis by a factor of 102, using multicomponent stereolithographic printing. Automatic sample evaluation is achieved via Raman spectroscopy and similarity analysis without any sample preparation.

Deposition Rate‐Controlled Functional Evolution of p‐Type Selenium‐Alloyed Tellurium–Tellurium Oxide Films for Thin‐Film Transistors

open access: yesAdvanced Science, EarlyView.
This study investigates the effects of thermal deposition rate on next‐generation p‐type amorphous oxide semiconductor SeTe–TeOx films. Deposition rate governs the chemical states, microstructure, and electrical characteristics of the films, resulting in tunable device properties.

Asymmetric Fluorinated Spiro Hole‐Transport Materials Enabled by a Rapid Core‐Forming Strategy for Blade‐Coated Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Facile synthesis of asymmetric fluorinated spiro‐type HTMs combined with blade‐coating fabrication and vacuum‐assisted crystallization enables high‐efficiency PSCs with PCEs of 24.49% (0.09 cm2) and 23.28% (1.00 cm2), along with excellent stability.

Programmable Guest‐Induced 5‐Phase‐Transition Topological Reconstructions of Cobalt Formate Metal–Organic Frameworks

open access: yesAdvanced Science, EarlyView.
A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

open access: yesAdvanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Thermogravimetric analysis of a talc mixture

open access: yesThermochimica Acta, 1992
A commercial talc also containing chlorite, dolomite and magnesite was subjected to thermogravimetric analysis to determine its mineral composition. Knowledge of the reactions and the decomposition temperatures, as well as the crystallochemical formulae of the phases present, has permitted the application of a system of equations that has provided ...

Thermogravimetric analysis of chitosan

Journal of Applied Polymer Science, 2007
AbstractThe thermal degradation of chitosan at different heating rates B in nitrogen was studied by thermogravimetric analysis. The results indicate that the thermal degradation of chitosan in nitrogen is a one‐step reaction. The degradation temperatures increase with B.

Thermogravimetric Analysis of Composite Restorative Resins

open access: yesJournal of Dental Research, 1972
Thermogravimetric analyses of six commercial brands of composite restorative resins were performed at temperatures from 25 to 700 C in air with a heating rate of 9.5 Cl minute. The reported ashed weight was assumed to be the filler weight. The thermogravimetric technique as applied to these composite resins was effective in deriving basic information ...
