Towards Uniform Online Spherical Tessellations [PDF]

arXiv, 2018
The problem of uniformly placing N points onto a sphere finds applications in many areas. For example, points on the sphere correspond to unit quaternions as well as to the group of rotations SO(3) and the online version of generating uniform rotations (known as "incremental generation") plays a crucial role in a large number of engineering ...

Associations of Fire Smoke and Other Pollutants With Incident Rheumatoid Arthritis and Rheumatoid Arthritis–Associated Interstitial Lung Disease

Arthritis &Rheumatology, EarlyView.
Objective The aim of this study was to determine whether pollutants such as fire smoke–related particulate matter <2.5 μm (PM2.5) are associated with incident rheumatoid arthritis (RA) and RA‐associated interstitial lung disease (RA‐ILD). Methods This patient–control study used Veterans Affairs (VA) data from October 1, 2009, to December 31, 2018.

A novel decision support system for designing and assessing phytoremediation‐to‐biofuel value chains

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The design of biofuel value chains is a complex process due to the large number of stakeholders involved, seasonality in feedstock availability, security of supply, logistics costs, efficiency considerations, and its multi‐node nature. Decisions on designing phytoremediation‐to‐biofuel value chains are even more complicated, due to the ...

In Situ Electrochemically Deposited Mg Seeds Stabilizing the Lithium Metal Anode

ChemElectroChem, Volume 12, Issue 6, March 15, 2025.
In situ Mg seeds are generated on the lithium metal surface during cycling by incorporating MgCl2 into the electrolyte. These Mg seeds function as thiophilic sites, which lower the Li nucleation barrier and promote uniform Li nucleation and growth. Consequently, symmetric cells constructed with the carbonate electrolyte can cycle stably for over 400 h ...

Computational Evaluation of Redox Potentials of Metal Complexes for Aqueous Flow Batteries

ChemPhysChem, EarlyView.
Experimental and computational screening of redox potentials of several metal complexes is done. Computationally a large set of metal and ligand combinations has been studied. M = Fe,Ni,Ti,Mn, ligands include PIB, EDTA, cathecol, terpy, DIPSO. Most of the ligands are modified with functional groups. Flow batteries are a promising option for large‐scale
