Approximate Method of Calculating Heating Rates at General Three-Dimensional Stagnation Points During Atmospheric Entry [PDF]

open access: yes
An approximate method for calculating heating rates at general three dimensional stagnation points is presented. The application of the method for making stagnation point heating calculations during atmospheric entry is described.

Bifunctional Mesoporous MO x (M = Cr, Fe, Co, Ni, Ce) Oxygen Electrocatalysts for Platinum Group Metal‐Free Oxygen Pumps

open access: yesEnergy Technology, Volume 10, Issue 12, December 2022., 2022
The family of high‐quality crystalline mesoporous MOx synthesized via soft‐templated hydrothermal synthesis is investigated in oxygen reduction reaction and oxygen evolution reaction electrocatalysis. Using developed NiO, the symmetrical platinum group metal‐free oxygen pump is elaborated for the first time.

Asymptotic structure incorporating double and triple decks, original version [PDF]

open access: yesarXiv, 2018
The stagnation point flow toward a rotating disk of finite radius is known to develop -- near the edge of the disk -- into a triple deck structure when the flow is strictly a stagnation point flow, and into a double deck structure when the flow is strictly a rotating disk flow.

Blowup in Stagnation-point Form Solutions of the Inviscid 2d Boussinesq Equations [PDF]

open access: yes, 2015
The 2d Boussinesq equations model large scale atmospheric and oceanic flows. Whether its solutions develop a singularity in finite-time remains a classical open problem in mathematical fluid dynamics.

Plastics of the Future? Interdisciplinary Review on Biobased and Biodegradable Polymers: Progress in Chemistry, Societal Views, and Environmental Implications

open access: yesAngewandte Chemie International Edition, Accepted Article.
Global demand to reduce polymer waste and microplastics pollution has increased in recent years, prompting further research, development, and wider use of biodegradable and biobased polymers (BBPs). BBPs have emerged as promising alternatives to conventional plastics, with the potential to mitigate the environmental burdens of persistent plastic waste.
