An unexpected cause of severe and refractory PTH-independent hypercalcemia: case report and literature review

Archives of Endocrinology and Metabolism
Hypercalcemia is a common condition in the internal medicine practice. Sometimes its cause is not readily apparent, so extensive investigation is appropriate. Here we report an unexpected cause for hypercalcemia in an elderly woman.

Conjugated Inorganic–Organic Hybrid Polymers with p‐Block Elements

Angewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
The influence of various p‐block element motifs on the photophysical properties of conjugated inorganic‐organic hybrid polymers is surveyed regarding applications in organic electronics. Recent advances in the use of heavier elements as well as heavier multiple bonds and the development of diverse (post‐)functionalization strategies suggest ample scope

Zinc Grid Based Transparent Electrodes for Organic Photovoltaics

Advanced Energy Materials, Volume 16, Issue 3, 21 January 2026.
A transparent flexible electrode based on an embedded zinc grid with ≈1 µm linewidth is reported, and its utility as a drop‐in replacement for indium‐tin oxide coated glass electrodes in organic photovoltaic devices is demonstrated. The zinc grids are fabricated using the unconventional approach of condensation coefficient modulation, using a ...

Physeal Allograft Transfer for Physeal Bars: A Safety and Feasibility Study in a Domestic Swine Model

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT Premature physeal closure occurs following trauma, cancer, or infection. Current treatments have poor success rates. With recent pediatric donor tissue availability, physeal allograft transfer (PAT) can now be considered. The purpose of this study was to study the safety and feasibility of PAT in a large animal model.

Controlled Cross‐Linking for Water Developable Hf‐Based Dry Resist Prepared via Molecular Layer Deposition

Small Structures, Volume 7, Issue 1, January 2026.
A strategy for tuning the cross‐linking density in molecular layer deposition (MLD) films is demonstrated by leveraging the double reaction and nonring‐opening pathways of ε‐caprolactone. Using this approach, hafnium–ε‐caprolactone MLD film exhibits intrinsic water solubility.
