Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

20-hydroxyecdysone dilates muscle arterioles in a nitric oxide-dependent, estrogen ER-β receptor-independent manner

open access: yesPhytomedicine Plus, 2021
Background: 20-hydroxyecdysone is an ecdysteroid which is abundant in plants and insects and has anabolic potentials in mammals. It was recently shown to have affinity for estrogen ER-β receptor, which could potentially make it vasodilatory.

Determinants of the intention to use performance-enhancing substances among Portuguese gym users [PDF]

open access: yes, 2020
The present study examined the determinants of the intentions to use prohibited performance- enhancing substances (PES) and the hypothesis of gender and PES use influencing Theory of Planned Behavior (TPB) variables. A TPB approach was used.

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

open access: yesAdvanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

A systematic review on the effectiveness of anti-doping education for university students

open access: yesEmerging Trends in Drugs, Addictions, and Health
Background: Doping poses a threat to the integrity of sport and the health of athletes who dope, including university students. In this systematic review, we identified the content of anti-doping education that universities provide, the disciplines ...

Creating a corporate anti-doping culture: Understanding the role of sport governing bodies [PDF]

open access: yes, 2006
The World Anti-Doping Agency’s (WADA) vision to promote a new moral order in sport and new forms of organisation and management through the World Anti Doping code (WADC) amount to creating a new corporate culture. WADC’s emphasis on policy implementation

Sensitivity and specificity of detection methods for erythropoietin doping in cyclists [PDF]

open access: yes, 2019
Recombinant human erythropoietin (rHuEPO) is used as doping a substance. Anti-doping efforts include urine and blood testing and monitoring the athlete biological passport (ABP).

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Development and validation of a fast gas chromatography combustion isotope ratio mass spectrometry method for the detection of epiandrosterone sulfate in urine [PDF]

open access: yes, 2020
In doping control, to confirm the exogenous origin of exogenously administered anabolic androgenic steroids (AAS), a gas chromatography combustion isotope ratio mass spectrometry (GC-C-IRMS) analysis is performed.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
