Beyond Cocrystals: Hierarchical Functional Assemblies via Noncovalent Synthesis

Advanced Science, EarlyView.
Non‐covalent interactions (NCIs) drive the formation of organic cocrystals with diverse structures and tunable optoelectronic properties. This review explores the essential factors governing these properties, highlighting how the sequential nucleation of cocrystals leads to the self‐assembly of organic hierarchical structures (OHSs).

New Hybrid Cascaded Multilevel Inverter

International Journal of Engineering, 2013
A B S T R A C T This paper proposes a single-phase five-level inverter with a modified pulse width- modulated (PWM) control scheme. The modified pulse width-modulation technique is developed to reduce switching losses. Also, the proposed multilevel inverter can reduce the requirement of power switches compared to a conventional cascaded multilevel ...

Enriched Environment Enhances Motor Function in Mice With Cerebral Infarction by Promoting mTOR‐Dependent Autophagy in the Contralateral Dentate Nucleus

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Although environmental enrichment (EE) promotes post‐stroke motor recovery, the mechanisms underlying its regulation of cerebellar dentate nucleus (DN) plasticity remain unclear; this study therefore investigated how EE coordinates autophagy, mitochondrial homeostasis, and synaptic remodeling in the contralateral DN to facilitate functional ...
