Future Trends in Alternative Sustainable Materials for Low-Temperature Thermoelectric Applications.

In the evolution of pervasive electronics, it is imperative to significantly reduce the energy consumption of power systems and embrace sustainable materials and fabrication processes with minimal carbon footprint. Within this context, thermoelectric generators (TEGs) have garnered substantial attention in recent years because of the readily available thermal gradients in the environment, making them a promising energy-harvesting technology. Current commercial room-temperature thermoelectrics are based on scarce, expensive, and/or toxic V-VI chalcogenide materials, which limit their widespread use.

ZrN-Based Multilayers Prepared by Reactive Sputtering as Coatings for Electrode Plates of Proton Exchange Membrane Water Electrolyzers.

ZrN and TiN thin coatings have been investigated for use on stainless steel for bipolar plates of proton exchange membrane water electrolyzers. Films were deposited by reactive magnetron sputtering using Ar and N from metallic Zr and Ti targets on different substrates to perform a deep characterization of their relevant properties. The effect of the deposition parameters, such as N/Ar ratio, working pressure, or supplied power, has been explored.

Durable left ventricular assist devices following temporary circulatory support on a microaxial flow pump with and without extracorporeal life support.

Background: Circulatory support with a catheter-based microaxial flow pump (mAFP) plays a major role in the treatment of severe cardiogenic shock. In most patients who fail to recover while on temporary mechanical circulatory support (tMCS) and who are not eligible for heart transplantation, durable left ventricular assist device (dLVAD) implantation is usually considered a reliable option. This study aimed to describe the outcome of dLVAD therapy following mAFP support and to identify predictors of mortality.

Peripheral precocious puberty secondary to severe hypothyroidism.

Van Wyk-Grumbach syndrome is a rare form of severe hypothyroidism. We present a 10.9-year-old girl who consulted for genital bleeding, Tanner stage 2, and clinical manifestations of hypothyroidism.

Different ECLS Pump Configurations for Temporary Right Ventricular Assist Device in LVAD Patients: A Retrospective Case-Control Study.

Background: Acute right ventricular failure is a critical complication after left ventricular assist device (LVAD) implantation, often managed with a temporary paracorporeal right ventricular assist device (RVAD). This study examined three extracorporeal life support (ECLS) systems regarding mortality, bleeding complications, and intensive care unit (ICU) stay duration.

Methods: This monocentric, retrospective case-control study included all patients receiving LVAD with paracorporeal RVAD between 2009 and 2020.
