Gold‐ and Silver‐Coated Barium Titanate Nanocomposites as Probes for Two‐Photon Multimodal Microspectroscopy
Improved multiphoton‐excited imaging and microspectroscopy require nanoprobes that can give different nonlinear optical signals. Here, composite nanostructures with a barium titanate core and a plasmonic moiety at their ...
Direct Observation of Conductive Polymer Induced Inversion Layer in n-Si and Correlation to Solar Cell Performance
Heterojunctions formed by ultrathin conductive polymer [poly(3,4‐ethylenedioxythiophene): poly(styrenesulfonate)—PEDOT:PSS] films and n‐type crystalline silicon are investigated by photoelectron spectroscopy. Large shifts ...
Copper Thiophosphate (Cu3PS4) as Electrode for Sodium-Ion Batteries with Ether Electrolyte
Sections PDFPDF Tools Share Abstract Lithium and sodium thiophosphates (and related compounds) have recently attracted attention because of their potential use as solid electrolytes in solid‐state batteries. These ...
Gas Sensing of NiO-SCCNT Core–Shell Heterostructures
Optimization by Radial Modulation of the Hole-Accumulation Layer
Hierarchical core–shell (C–S) heterostructures composed of a NiO shell deposited onto stacked‐cup carbon nanotubes (SCCNTs) are synthesized by atomic layer deposition (ALD). A film of NiO particles (0.80–21.8 nm in thickness) ...
Assessment on the Use of High Capacity “Sn4P3”/NHC Composite Electrodes for Sodium-Ion Batteries with Ether and Carbonate Electrolytes
This work reports the facile synthesis of a Sn–P composite combined with nitrogen doped hard carbon (NHC) obtained by ball‐milling and its use as electrode material for sodium ion batteries (SIBs). The “Sn4P3”/NHC electrode ...
A Co- and Ni-Free P2/O3 Biphasic Lithium Stabilized Layered Oxide for Sodium-Ion Batteries and its Cycling Behavior
Cobalt‐ and nickel‐free cathode materials are desirable for developing low‐cost sodium‐ion batteries (SIBs). Compared to the single P‐type and O‐type structures, biphasic P/O structures become a topic of interest thanks ...
Graphene-Mercury-Graphene Sandwich Electrode for Electroanalysis
We present a new class of hybrid 2D electrodes, where mercury is incorporated between two graphene monolayers, prepared by bottom-up assembly. First, the bottom graphene layer is electrochemically modified leading to the ...
