Neuromodulation strategies are increasingly needed to stimulate, restore, or replace altered neuronal activity in disease. Cobalt ferrite‐barium titanate (CFO–BTO) magnetoelectric nanoparticles convert low‐intensity static magnetic fields into local electrical modulation of cortical networks.

A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators
This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.

În anticamera unui nou bipolarism global
This paper looks at changes in international order nowadays, with a focus on debates about unipolarity and multipolarity. The hypothesis of the study is that the world is currently experiencing a short stage of uni-multipolarity, characterised by high ...

In the Antechamber of a New Global Bipolarity [PDF]
This paper investigates the shifts in the international balance of power, that we attribute both to the weakening status of the US globally and to the rise of regional powers.

The end of the 'new world order'?: Security governance and US imperialism after 9/11 [PDF]
The concept of global governance has emerged as a key theoretical approach since the 1990s. Applied to the transformation of international security, it has suggested a shift from the state-dominated bipolar system of the Cold War era to a new multipolar ...

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors
A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors
Lead‐free barium strontium titanate multilayer capacitors convert waste heat into electricity via the Olsen electro‐thermodynamic cycle. These capacitors achieve an energy density of 3.7 J cm−3, comparable to the performance of lead‐based ceramics. Their high dielectric strength and broad operating temperature window below 100°C make them practical for

Beyond Radical Emitters: Hot‐Exciton Electroluminescence From Singlet Diradicaloids
The first hot‐exciton mechanism in a singlet diradicaloid is demonstrated in a polychlorinated Thiele hydrocarbon‐based organic light‐emitting transistor. Reverse intersystem crossing involving the T2 and bright singly excited states enables electroluminescence beyond the 25% spin‐statistical limit, leading to remarkable external quantum efficiency ...

Different forms of polarity in neorealism and world-systems theory [PDF]
Modern world relations are characterized by the dissolution of American unipolarity and chaotic international relations. This change in the sphere of geopolitics is no doubt related to the restructuring of the world capitalist system in which the USA is ...
