Octupolar AIEgens Photosensitizers With Enhanced Molar Absorptivity for Near‐Infrared Phototheranostics

open access: yesAggregate, Volume 7, Issue 5, May 2026.
Symmetry‐guided molecular engineering transforms dipolar AIEgens into octupolar AIEgens (D(A)3) with enhanced NIR‐II absorptivity. The octupolar architecture activates additional S0→S2 transitions and promotes efficient intersystem crossing, leading to strong reactive oxygen species generation.

Design optimization of a slotless PM brushless motor with spiral wound laminations for rim driven thrusters

open access: yes, 2009
This paper discusses the analysis and design of a very thin slotless PM brushless motor whose stator laminations are manufactured from a single strip of steel that is edge wound into a spiral (like a “Slinky”) and then fitted over the windings that are ...

Nanometric Faujasite (FAU) Zeolite Ion‐Exchanged With Metal Ions for Hemostatic and Antimicrobial Applications: A Thromboelastographic and Microbiological Study

open access: yesChemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.
Faujasite nanozeolite (NanoFAU) and its ion‐exchanged forms (Ag+, Ba2+, Ca2+, Mg2+) were synthesized and characterized to assess their biomedical potential. NanoFAU‐Ca showed superior hemostatic activity, while NanoFAU‐Ag exhibited strong antimicrobial effects against S. aureus and C. albicans.

Opening closed inward rectifier potassium channel doors

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 10, Page 2197-2218, May 2026.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

Identification of miR‐150‐5p in Human Amniotic Membrane Mesenchymal Cell‐Derived Extracellular Vesicles as a Novel Mechanism Driving Cardioprotection

open access: yesEuropean Journal of Clinical Investigation, Volume 56, Issue 5, May 2026.
Human amniotic membrane mesenchymal stem cells (hAMSCs) provide significant cardioprotection following myocardial ischemia/reperfusion injury. They improve cardiac function and reduce fibrosis by modulating the MIAT/miR‐150‐5p/HOXA4 signalling axis.

Optimization of an axial-flux permanent-magnet generator for a small wind energy application [PDF]

open access: yes, 2011
Axial-flux permanent-magnet synchronous machines have a high torque output at low speeds and are therefore very suitable for direct drive wind energy applications.

Modelling and Control of an Annular Momentum Control Device [PDF]

open access: yes
The results of a modelling and control study for an advanced momentum storage device supported on magnetic bearings are documented. The control challenge posed by this device lies in its dynamics being such a strong function of flywheel rotational speed.

In-wheel axial-flux SRM drive for light electric vehicles [PDF]

open access: yes, 2018
Revenues from global sales of light electric vehicles are expected to grow from $ 9.3 billion in 2017 to $ 23.9 billion in 2025. In order to boost this growth electric drives with better features and lower costs have to be developed.

Design definition of a mechanical capacitor [PDF]

open access: yes
A design study and analyses of a 10 kW-hr, 15 kW mechanical capacitor system was studied. It was determined that magnetically supported wheels constructed of advanced composites have the potential for high energy density and high power density ...
