Nitrogen-doped amorphous monolayer carbon.

Monoatomic-layered carbon materials, such as graphene and amorphous monolayer carbon, have stimulated intense fundamental and applied research owing to their unprecedented physical properties and a wide range of promising applications. So far, such materials have mainly been produced by chemical vapour deposition, which typically requires stringent reaction conditions compared to solution-phase synthesis. Herein, we demonstrate the solution preparation of free-standing nitrogen-doped amorphous monolayer carbon with mixed five-, six- and seven-membered (5-6-7-membered) rings through the polymerization of pyrrole within the confined interlayer cavity of a removable layered-double-hydroxide template.

regulates gustatory habituation in sweet taste neurons and mediates sugar ingestion in .

Similar to other animals, the fly, reduces its responsiveness to tastants with repeated exposure, a phenomenon called gustatory habituation. Previous studies have focused on the circuit basis of gustatory habituation in the fly chemosensory system. However, gustatory neurons reduce their firing rate during repeated stimulation, suggesting that cell-autonomous mechanisms also contribute to habituation.

Visual feedback neurons fine-tune Drosophila male courtship via GABA-mediated inhibition.

Many species of animals use vision to regulate their social behaviors. However, the molecular and circuit mechanisms underlying visually guided social interactions remain largely unknown. Here, we show that the Drosophila ortholog of the human GABA-receptor-associated protein (GABARAP) is required in a class of visual feedback neurons, lamina tangential (Lat) cells, to fine-tune male courtship.

GABA-mediated inhibition in visual feedback neurons fine-tunes male courtship.

Vision is critical for the regulation of mating behaviors in many species. Here, we discovered that the ortholog of human GABA -receptor-associated protein (GABARAP) is required to fine-tune male courtship by modulating the activity of visual feedback neurons, lamina tangential cells (Lat). GABARAP is a ubiquitin-like protein that regulates cell-surface levels of GABA receptors.

Observation of robust zero-energy state and enhanced superconducting gap in a trilayer heterostructure of MnTe/BiTe/Fe(Te, Se).

The interface between magnetic material and superconductors has long been predicted to host unconventional superconductivity, such as spin-triplet pairing and topological nontrivial pairing state, particularly when spin-orbital coupling (SOC) is incorporated. To identify these unconventional pairing states, fabricating homogenous heterostructures that contain such various properties are preferred but often challenging. Here, we synthesized a trilayer-type van der Waals heterostructure of MnTe/BiTe/Fe(Te, Se), which combined s-wave superconductivity, thickness-dependent magnetism, and strong SOC.

Effect of heat treatment on the microstructure and ablation performance of C/C-SiC composites containing ZrSi-Si.

Low-temperature reactive melt infiltration (LRMI) is advantageous for the fabrication of ceramic matrix composites (CMCs). However, residual metal in CMCs prepared by LRMI deteriorates the high-temperature properties. In this study, C/C-SiC composites containing ZrSi-Si were prepared using LRMI at 1400 °C, and the effect of heat treatment at 1400 °C for 10, 20, or 30 h on the microstructure and ablation properties of the composites fabricated using three different ternary alloys (, ZrBSi, ZrBSi, and ZrBSi) was investigated.
