A new family of boost active neutral point clamped inverter topology with reduced switch count

open access: yesIET Power Electronics, 2021
A new family of inverter topology for active neutral point clamped (ANPC) is proposed. The traditional ANPC gives the output voltage of half the input voltage which necessitates the use of higher input dc‐link voltage.

Modulating Interfacial Potential Gradients in Metal−Carbon Catalysts via Phase‐Engineering for Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
It is elucidated that phase engineering of cobalt modulates the interfacial potential gradients of cobalt–carbon electrocatalysts, enhancing the intrinsic electrocatalytic performance. Modulating the dominant crystalline phase of cobalt from a hexagonal close‐packed to a face‐centered cubic enriches the electron density of carbon shells, thereby ...

Conductance‐Dependent Photoresponse in a Dynamic SrTiO3 Memristor for Biorealistic Computing

open access: yesAdvanced Functional Materials, EarlyView.
A nanoscale SrTiO3 memristor is shown to exhibit dynamic synaptic behavior through the interaction of local electrical and global optical signals. Its photoresponse depends quantitatively on the conductance state, which evolves and decays over tunable timescales, enabling ultralow‐power, biorealistic learning mechanisms for advanced in‐memory and ...

High Energy Density Asymmetric Aqueous Supercapacitor Based on a 2D Manganese Carbide as a Positive Electrode

open access: yesAdvanced Functional Materials, EarlyView.
A circular route, involving upcycling of waste surgical masks, affords a Mn‐based layered carbide with porosity, redox activity and low work function. These features enable its effective operation as positive supercapacitor electrode in an aqueous asymmetric supercapacitor delivering 213 Wh L−1 energy density.

Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.

Few‐Layered Conductive Graphene Foams for Electrical Transdifferentiation of Mesenchymal Stem Cells Into Schwann Cell‐Like Phenotypes

open access: yesAdvanced Healthcare Materials, EarlyView.
Few‐layered three dimansional conductive graphene foams are promising cytocompatible platforms to transdifferentiate mesenchymal stem cells into Schwann cell‐like phenotypes using electrical and microstructural cues. Applied electrical stimulation conditions resulted in activation of MAPK, neurotrphin and RAS signaling pathways that led to upregulation
