Using the HClO4–H2O2 System for Efficient Platinum Leaching: Optimal Conditions and Kinetics

ChemPlusChem, Volume 90, Issue 8, August 2025.
GA: The platinum leaching using HClO4 and H2O2 is studied. For each HClO4 concentration, an H2O2/HClO4 = 2.5 ratio optimizes the kinetics. The best operating conditions are ≈70 °C, [HClO4] 3 m, and [H2O2] 7.2 m. The leaching process is governed by diffusion in the boundary layer and chemical reaction. In this new extraction process, Cl2(g) is generated

Comparison of Globorisk, SCORE2, and PREVENT in the Stratification of Cardiovascular Risk and its Relationship with End‐Organ Damage Among Adults With Arterial Hypertension

The Journal of Clinical Hypertension, Volume 27, Issue 8, August 2025.
ABSTRACT Arterial hypertension often coexists with comorbidities that increase vascular damage. Although the primary goal is to reduce cardiovascular risk, the available risk scores can produce varying estimates. Here, we aim to compare the prevalence of cardiovascular risk categories using three equations (Globorisk, SCORE2, and PREVENT) in adults ...

Interactions of a $j=1$ boson in the $2(2j+1)$ component theory

, 1995
The amplitudes for boson-boson and fermion-boson interactions are calculated in the second order of perturbation theory in the Lobachevsky space. An essential ingredient of the used model is the Weinberg's $2(2j+1)$ component formalism for describing a ...

Diversity Hotspots and Vulnerability of Pine Species in the Sierra Madre Occidental, Western Mexico

Ecology and Evolution, Volume 15, Issue 7, July 2025.
The present study employs a modeling approach to examine the current and future distribution of 19 pine species in the Sierra Madre Occidental, Mexico. This was done in order to identify areas with high potential for pine species richness and to determine which species are at risk due to climate change under different projections.
