Ashwagandha: Is It Safe? Part 1: A Regulatory Review

Phytotherapy Research, EarlyView.
ABSTRACT Over the last decade, ashwagandha (Withania somnifera (L.) Dunal, AS) has been brought under increasing scrutiny by EU regulators regarding its safety for the use in food supplements, culminating in a recent recommendation for an Article 8 procedure according to Regulation (EC) No. 1925/2006 in the European Union (EU).

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Titanium Dioxide Induced Immobilization of Small Platinum Nanoparticles on Carbon Spherogels: A Strategy Towards Stable and Efficient Electrocatalysts for the Hydrogen Evolution Reaction

Small, EarlyView.
Platinum nanoparticles are immobilized on hollow carbon spherogels using supercritical deposition, enabling precise control over nanoparticle size, loading, and spatial distribution. Incorporation of an internal TiO2 sublayer in the hollow sphere support induces enhanced metal–support interactions, markedly improving hydrogen evolution activity and ...

A Highly Porous Nanofibrillar PEDOT:PSS Matrix for Beyond‐Surface Precious‐Metal Utilization and Volumetric Electrocatalysis

Small, EarlyView.
Solvent‐assisted crystallization transforms PEDOT:PSS into a conductive nanoporous scaffold that enables volumetric incorporation and utilization of Pt nanoparticles. Unlike surface‐limited Pt only electrodes, the PP–Pt electrode allows ion penetration and bulk catalyst activation, improving precious‐metal utilization and sustaining electrocatalytic ...

Plasma Enabled Synthesis of Dual Phase Alkali Metals (Li, Na, K) & Water Co‐Intercalated V2O5 3D TMO Clusters for High Performing Aqueous Zinc Ion Battery

Small, EarlyView.
ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted considerable attention as a safe and cost‐effective to energy storage system. Cathode materials, which are critical to determining overall AZIB performance, remain a major hurdle to deployment.

Computer Modeling of the Ferrite‐To‐Austenite Transformation in a Super‐Duplex Stainless Steel and the Important Role of Trans‐Interface Diffusion

steel research international, EarlyView.
An accurate moving boundary model for volume diffusion containing boundary conditions from trans‐interface diffusion (TID) simulates the austenite growth during cooling. TID of Cr, Mo, N and Ni enhance growth kinetics. Without TID, compositions of the interface region change, decreasing the driving force for growth and finally causing numerical ...
