Bicontinuous Interconnected Porous Biomaterials for Tissue Engineering and Regeneration

open access: yesSmall Science, EarlyView.
Solvent transfer‐induced phase separation transforms bioinert polyethylene glycol diacrylate into bioactive scaffolds featuring bicontinuous interconnected porosity, with negative Gaussian curvature, and unique topographical patterning. These attributes enable stem cell attachment, proliferation, and differentiation without basement membrane matrix ...

Biological J‐Coupling Spectroscopy at Low Magnetic Field

open access: yesSmall Science, EarlyView.
The strong J(C,H)‐coupling from [2‐13C] pyruvate is exploited to measure the pyruvate‐to‐lactate conversion in cancer cells at low magnetic fields. This is combined with a parahydrogen‐induced polarizationprotocol optimized to provide a biocompatible solution with 20 000‐fold signal enhancement.

First‐Principles Study on the Interfacial Cathode‐Contact Stability and Li Diffusivity of N‐Doped Li6Zr2O7 for All‐Solid‐State Li‐Ion Batteries

open access: yesSmall Methods, EarlyView.
This study presents the investigation of N‐doped Li6Zr2O7 by first‐principles density functional theory methods to evaluate its (electro)chemical stability and Li‐ion transport properties for its novel design as a practical dual‐use Li ionic conductor for cathode‐coating layer and solid electrolyte application in all‐solid‐state Li‐ion batteries ...

DESIGN AND EVALUATION OF A HORSE SADDLE USING CAD SOFTWARE

open access: yesJournal of Industrial Design and Engineering Graphics
The pressure on a horse's back can affect their performance during the equestrian competition. A better pressure distribution on the surface of the horse's back can be obtained using a custom saddle, considering the rider's weight and back anatomy.

Core Extended Conjugation in Thiophene‐Based Cations Enables Open‐Circuit Voltage Improvement in Inverted Perovskite Solar Cells

open access: yesSolar RRL, EarlyView.
This work investigates thiophene‐based cations for surface passivation in inverted perovskite solar cells. Double‐thiophene methylammonium iodide improves open‐circuit voltage, suppresses nonradiative recombination, and allows an improved power conversion efficiency.
