Revised treatment of wet scavenging processes dramatically improves GEOS-Chem 12.0.0 simulations of surface nitric acid, nitrate, and ammonium over the United States [PDF]
Geoscientific Model Development, 2019 The widely used community model GEOS-Chem 12.0.0 and previous versions have been recognized to significantly overestimate the concentrations of gaseous nitric acid, aerosol nitrate, and aerosol ammonium over the United States.

Advanced Engineering Materials, EarlyView.This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Advanced Engineering Materials, EarlyView.The functional properties of Fe–Mn–Si–Cr‐based shape memory alloys are influenced, among other things, by their chemical composition. Here, the vaporization of Mn, the most volatile element of the alloy, is investigated. It is shown that the process parameters make noninterchangeable contributions to the vaporization and that vaporization differences ...

Advanced Engineering Materials, EarlyView.High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

Nucleation of nitric acid hydrates in polar stratospheric clouds by meteoric material [PDF]
Atmospheric Chemistry and Physics, 2018 Heterogeneous nucleation of crystalline nitric acid hydrates in polar stratospheric clouds (PSCs) enhances ozone depletion. However, the identity and mode of action of the particles responsible for nucleation remains unknown.

Key Trends and Insights in Smart Polymeric Skin Wearable Patches
Advanced Engineering Materials, EarlyView.Intelligent polymers, which respond to various physical and biological stimuli, are explored for the development of skin wearable patches in biomedical applications. Smart polymers, also known as intelligent or stimuli‐responsive polymers, play a crucial role in the development of advanced wearable patches due to their versatility and softness.

Nitrosation and Nitration of Fulvic Acid, Peat and Coal with Nitric Acid. [PDF]
PLoS ONE, 2016 Nitrohumic acids, produced from base extraction of coals and peats oxidized with nitric acid, have received considerable attention as soil ammendments in agriculture. The nitration chemistry however is incompletely understood.
