Spinel-Encapsulated Ni-Rich Cathodes for Enhanced Thermal Safety: Unraveling the Decomposition Kinetics and Interfacial Reconstruction [PDF]

open access: yesNanomaterials
High-energy Ni-rich layered cathodes are critical for next-generation lithium-ion batteries yet remain limited by severe interfacial degradation and thermal vulnerability under high-voltage operation. In this work, a robust spinel-layered heterostructure

Decomposition kinetics of maltose in subcritical water.

open access: yesBioscience, Biotechnology and Biochemistry, 2004
The decomposition process of maltose in subcritical water was studied using a tubular reactor in the temperature range of 180 to 260 degrees C and at 10 MPa. The formation of glucose and 5-hydroxymethyl-2-furaldehyde during the maltose decomposition was also observed. The decomposition rate of maltose was faster at higher temperatures.

Thermal decomposition of a molecular material {N(n-C4H9)4[FeIIFeIII(C2O4)3]}∞ leading to ferrite: A reaction kinetics study [PDF]

open access: yesJournal of the Serbian Chemical Society, 2013
A multi-step thermal decomposition of a molecular precursor, {N(n-C4H9)4[FeIIFeIII(C2O4)3}∞ has been studied using non-isothermal thermogravimetry (TG) measurements in the temperature range 300 to ~800 K at multiple heating rates (5, 10 and 20 K min-1)

Decomposition rate as an emergent property of optimal microbial foraging

open access: yesFrontiers in Ecology and Evolution, 2023
Decomposition kinetics are fundamental for quantifying carbon and nutrient cycling in terrestrial and aquatic ecosystems. Several theories have been proposed to construct process-based kinetics laws, but most of these theories do not consider that ...

General analytical solution expressions for analyzing Langmuir-type kinetics of sonochemical degradation of nonvolatile organic contaminants in water

open access: yesUltrasonics Sonochemistry, 2023
Detailed kinetic studies of the ultrasonic decomposition of contaminants in water are scarce. Most of the work has used a pseudo-first order kinetics law, which is unrealistic.

Kinetic Decomposition for Periodic Homogenization Problems [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2009
We develop an analytical tool which is adept for detecting shapes of oscillatory functions, is useful in decomposing homogenization problems into limit-problems for kinetic equations, and provides an efficient framework for the validation of multi-scale asymptotic expansions.

A Kinetic Evaluation for Phenothiazine Based Copolymers

open access: yesHittite Journal of Science and Engineering, 2021
In here, the nonisothermal decomposition kinetics of co-polymers based phenothiazine was present-ed. For this, firstly, 3, 7-di-2-thienyl-10H-phenothiazine (TF) was prepared via an optimized Suzu-ki–Miyaura cross-coupling reaction.
