Long‐Term Stable Subdural Recordings Enabled by Fibrosis‐Resistant Hydrogel‐Integrated µECoG Arrays

Advanced Science, Volume 12, Issue 47, December 18, 2025.
An adhesive hydrogel‐integrated micro‐electrocorticography (aGel‐µECoG) array is developed to ensure stable neural recordings by minimizing neuroinflammation and fibrosis during implantation. The hydrogel serves as a biological and mechanical bridge, enabling bioadhesive, reversible, anti‐fibrotic integration with brain tissue.

Trivalent Rare Earth Adsorption at Phosphonic Acid Monolayers

ChemPhysChem, Volume 26, Issue 20, October 15, 2025.
This study explores neodymium (Nd) adsorption on Langmuir monolayers of octadecylphosphonic acid (ODPA) at the air/water interface. Using sum frequency generation spectroscopy and X‐ray fluorescence near total reflection, how Nd ions enhance ODPA deprotonation and drive interfacial water ordering is revealed. The findings challenge classical models and

Solution‐Like Water Transport Across Molecular to Macroscopic Length Scales in Crosslinked Poly(Ethylene Glycol Diacrylate) Networks With Tailored Sidechains

Journal of Polymer Science, Volume 63, Issue 19, Page 3990-4002, 1 October 2025.
Cross‐linked PEGDA network microparticles are synthesized with spin labels to sense local water motion. From the nanoscale to the macroscale, PEGDA exhibits rapid, solution‐like water transport as measured by spectroscopic techniques. Addition of side chain chemistries further modulates local water diffusion.

Lipidomics‐Guided Ultrasound‐Assisted Ethanol Extraction of Avocado Pulp and Evaluation of Bioactive Properties

Journal of Food Science, Volume 90, Issue 10, October 2025.
ABSTRACT Avocados are a valuable source of lipids with potential applications in food, nutraceutical, and cosmetic products, all requiring food‐grade and environmentally friendly extraction methods. Though often enjoyed fresh, avocado pulp is also processed for oil.

Brown Grease as a Precursor to Polyol Monomer for Polyurethane Synthesis

ChemistrySelect, Volume 10, Issue 33, September 1, 2025.
In this study, we explore the functionalization of low‐value fats from brown grease via transesterification and the thiol‐ene reaction to afford polyol monomers capable of undergoing step‐growth polymerization to form polyurethanes (PUs). The capability of this two‐step functionalization process to develop copolymers from low‐value fats will provide a ...

Development and Validation of the Agency in Contraceptive Decisions Scale in Uganda and Nigeria

Studies in Family Planning, Volume 56, Issue 3, Page 655-675, September 2025.
Abstract To fill a gap in measures of empowered contraceptive decision‐making, we developed the Agency in Contraceptive Decisions Scale in Uganda and Nigeria. We developed an item pool drawing on the previously published Contraceptive Agency framework. We refined items through cognitive interviews (N = 80) and expert feedback and piloted a reduced item

Multi‐Mode Mechanochromic Responses from Cholesteric Liquid Crystal Elastomer Tubes of Uniform Sheath

Advanced Materials, Volume 37, Issue 34, August 28, 2025.
The structural‐colored tube is created from cholesteric liquid crystal elastomers, exhibiting uniform color changes with high strain sensitivity upon extension and inflation. The color change occurs across multiple mechanochromic modes, highlighting the influence of molecular anisotropy and tubular geometry on strain sensitivity.
