Soil ecosystem function loss under traditional gold mining landscapes in Tigray, Ethiopia: A function‐based soil quality indices approach

open access: yesSoil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Traditional gold mining (TGM) contributes to land degradation, yet its impacts on key soil ecosystem functions remain poorly understood. This study investigated soil degradation caused by TGM in Tigray, Ethiopia, to identify sensitive soil quality indicators and develop function‐based soil quality indices (SQIs), compare soil quality scoring ...

C2‐Symmetric Pseudopeptidic Schiff Bases Drive Discrete M2L2 Complexes: Coordination, Stability, and Photophysical Response [PDF]

open access: yesBioinorg Chem Appl
We report the design and synthesis of two new C2‐symmetric, multifunctional pseudopeptidic ligands derived from L‐valine and L‐phenylalanine that integrate dual Schiff‐base units (one per amino‐acid fragment) and an aromatic central spacer. These ligands were rationally engineered to favor the self‐assembly of discrete M2L2 architectures by combining ...

Bi‐Functional Topospecific Nanoparticles to Promote Immune‐Tumor Cell Engagement as A New Immunotherapeutic Strategy

open access: yesAdvanced Materials, Volume 38, Issue 2, 8 January 2026.
A Janus‐engineered nanoplatform (J‐pHLIP‐PD1), featuring separate tumor‐ and immune‐targeting faces, bridges melanoma cells and cytotoxic T lymphocytes using toposelective pHLIP and anti‐PD‐1 presentation. This strategy elicits robust antitumor responses, promotes immunogenic tumor cell death, suppresses lung metastasis in vivo, and provides a modular,
