Advanced Science, EarlyView.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.

Photoresponse Properties of Ambipolar Transport in WSe2 Field‐Effect Transistors
Advanced Electronic Materials, EarlyView.This study explores the photoresponse of WSe2 ambipolar field‐effect transistors, which exhibit unipolar, saturation, and ambipolar transport regions. Light illumination induces a shift of critical voltage with enhanced photocurrent generation driven by the photogating effect without the material degradation seen in avalanche photodetectors. This study

All‐Solution‐Processed Perovskite Light‐Emitting Transistors Enabled by a Fully Organic Architecture
Advanced Electronic Materials, EarlyView.Fully solution‐processed light‐emitting transistors based on CsPbBr3 perovskite nanocrystals (Pe‐LETs) are demonstrated using an all‐organic platform. By optimizing film formation and device integration, the Pe‐LETs achieve bright green emission with excellent color purity and a peak external quantum efficiency of 4.17 × 10−3 %, marking a step forward ...

În anticamera unui nou bipolarism global
Sociologie Românească, 2015 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]
Romanian Journal of European Affairs, 2016 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.

Model‐Based Time‐Modulated Write Algorithm for 1R Analog Memristive Crossbar Arrays
Advanced Electronic Materials, EarlyView.A novel model‐based time‐modulated write algorithm efficiently programs analog 1R memristive crossbar arrays by varying pulse duration at a fixed voltage. By leveraging a physics‐based compact model and a dynamic gain mechanism, this approach overcomes device nonlinearities and parasitic effects.

Different forms of polarity in neorealism and world-systems theory [PDF]
Sociološki PregledModern 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 ...

Advanced Electronic Materials, EarlyView.Through the introduction of a niobium oxide layer into a hafnia ferroelectric capacitor stack, we build a memory device with a strong imprint effect. This imprint leads to a millisecond retention loss that can be tuned by the programming conditions that can be utilized as a scalable, analog hardware time constant for bio‐inspired temporal computing ...

VISION OF MULTIPOLARITY IN RUSSIA AND CHINA AND INTERNATIONAL CHALLEANGES
Сравнительная политика, 2015 Throughout the last two decades the creation of a multipolar world was proclaimed more than once in bilateral documents signed by Russia and China. Meanwhile, even studies of scholars from those two countries testify that unipolarity remains in the ...
