Reactividad matriz-refuerzo en compuestos de matriz de titanio pulvimetalúrgico

Revista de Metalurgia, 2007
La elevada reactividad del titanio y la facilidad del mismo en formar intermetálicos dificulta la obtención de compuestos con este material y la necesidad, en todo caso, de recurrir al recubrimiento de las principales fibras utilizadas como refuerzo.

Counterions Determine if Metal‐Organic Cages Convert SO2 to Sulfate or Reversibly Adsorb It

Angewandte Chemie, Volume 137, Issue 11, March 10, 2025.
Different counterions modulate the solid‐state SO2 adsorption behavior in M6L8 Metal‐Organic Cages (M=Pd(II), Co(II), Cu(II), Zn(II)). Certain anions induce reversible SO2‐adsorption, while nitrate promotes its transformation to sulfate at room temperature.

Reactividad puzolánica de arcillas caoliníticasuna revisión [PDF]

Revista ingeniería de construcción, 2017
Pozzolans have demonstrated to be highly efficient mineral additions in the concrete industry, because they reduce the environmental impact generated by the cement manufacture, improve the physical, chemical and mechanical properties of blends, and reduce costs.

High Altitude Pregnancies and Vascular Dysfunction: Observations From Latin American Studies

Frontiers in Physiology, 2021
An estimated human population of 170 million inhabit at high-altitude (HA, above 2,500 m). The potential pathological effects of HA hypobaric hypoxia during gestation have been the focus of several researchers around the world.

Achieving Sub‐ppm Sensitivity in SO2 Detection with a Chemically Stable Covalent Organic Framework

Angewandte Chemie, Volume 137, Issue 3, January 15, 2025.
This study introduces the first experimental exploration of COFs for SO2 detection. The imine‐functionalized COF exhibited reversible SO2 sorption with over 50 cycles of reversibility. The isosteric enthalpy of adsorption was measured at −42.3 kJ/mol, reflecting a strong SO2‐COF interaction. Molecular dynamics and Møller–Plesset calculations elucidated

Efficacy of Der f 2/Zen 1‐LAMP1 Plasmid‐Based Vaccine Immunotherapy in Dogs With Atopic Dermatitis: A Proof‐of‐Concept Study

Veterinary Dermatology, Volume 37, Issue 2, Page 306-318, April 2026.
Background: DNA‐based vaccination rapidly induces strong cellular and humoral immune responses, which may be enhanced by inclusion of lysosomal‐associated membrane protein‐1 (LAMP). Objectives: This proof‐of‐concept study evaluated the efficacy and safety of a Der f 2/Zen 1‐LAMP‐based DNA vaccine immunotherapy in client‐owned dogs with nonseasonal AD ...

Tailoring Microstructure in Copper‐Based Conductive Metal–Organic Frameworks for Enhanced Chemiresistive Sensing and Uptake of Sulfur Dioxide

Advanced Functional Materials, Volume 36, Issue 26, 30 March 2026.
Precursor‐ and solvent‐mediated synthesis yields four Cu3(HHTP)2 morphologies with distinct physicochemical, sorption, and sensing properties toward SO2. Uptake capacities correlate with BET surface area, while sensing performance scales with particle aspect ratio.

Ginsenoside Rg1 as a Multifunctional Therapeutic Agent: Pharmacological Properties, Molecular Mechanisms and Clinical Perspectives in Complementary Medicine

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
Ginsenoside Rg1 (Rg1) from Panax ginseng shows multifunctional health effects. Although oral bioavailability is low and blood–brain barrier (BBB) penetration is limited, delivery systems such as liposomes and nanoparticles may improve exposure. Rg1 reduces inflammation/oxidative stress by inhibiting nuclear factor‐κB (NF‐κB) signaling and reactive ...
