Investigation of Firing Conditions and Boron Fluxes for the Optimized Synthesis of LiNi0.9Mn0.05Co0.05O2 for High Energy Density Li‐Ion Batteries

open access: yesChemElectroChem, EarlyView.
A short, low temperature, and oxygen‐free route to Ni‐rich NMC90 with high capacity and first‐cycle efficiency is achieved through a boron flux synthesis. The choice of boric acid or borax flux is shown be effective in tailoring the electrochemical performance of the cathode due to their different roles in stabilizing the bulk and surface structure ...

Tellurium‐Free, Sustainable Thermoelectric Device for Mid‐Temperature Waste Heat Recovery

open access: yesCarbon Energy, EarlyView.
We demonstrate the novel, low‐cost, non‐toxic, earth‐abundant p‐type and n‐type combination of materials for TEG fabrication. Sustainably fabricated TEG demonstrated a remarkable power of 5 mW and a maximum conversion efficiency of 4.6%. ABSTRACT Famatinite (Cu3SbS4, p‐type) and chalcopyrite (CuFeS2, n‐type) are well‐recognized sustainable minerals ...

Efficient formulation of a two‐noded geometrically exact curved beam element

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 124, Issue 3, Page 570-619, 15 February 2023., 2023
Abstract The article extends the formulation of a 2D geometrically exact beam element proposed by Jirásek et al. (2021) to curved elastic beams. This formulation is based on equilibrium equations in their integrated form, combined with the kinematic relations and sectional equations that link the internal forces to sectional deformation variables.
