Urinary Excretion Rate of Guanidinoacetic Acid in Essential Hypertension [PDF]

Nephron, 1988
The kidney is one of the major target organs in hypertension. Longterm persistent hypertension causes nephrosclerosis pathologicaly in 70–90% of patients1–2. Concerning the laboratory findings correlated with this pathological change, urinary micro-albumin (mAlb), s-2-microglobuline (RMG) and N-acetyl-D-glucosaminidase (NAG) have been reported as early

Enhancing Open‐Circuit Voltage and Fill Factor in Sn‐Based Perovskite Solar Cells: Challenges and Opportunities for Sustainable Photovoltaics

SusMat, Volume 5, Issue 6, December 2025.
This review summarizes advances in tin (Sn)‐based perovskite solar cells, a promising lead‐free alternative. It examines the main causes of Voc and fill factor losses, including Sn2+ oxidation, undercoordinated sites, and deep‐level traps. Strategies such as molecular coordination, surface passivation, compositional tuning, interface engineering, and ...
