Single‐Crystalline Lateral p‐SnS/n‐SnSe van der Waals Heterostructures by Vapor Transport Growth with In Situ Bi Doping

open access: yesAdvanced Functional Materials, EarlyView.
In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

Stoma‐Shell Nanoarchitecture for Enhanced Plasma Confinement Catalysis in Synthesis of Ethanol from CO2

open access: yesAdvanced Functional Materials, EarlyView.
High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.

Photoconductivity‐Driven Quantum Efficiency Gain in Inorganic Ruddlesden‐Popper Layered Cs2PbBr2I2 Perovskite Photodetector for Visible Light Detection

open access: yesAdvanced Functional Materials, EarlyView.
Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

Molecular determinants of presynaptic active zones

Current Opinion in Neurobiology, 2000
The presynaptic cytoskeletal matrix (cytomatrix) assembled at active zones has been implicated in defining neurotransmitter release sites. Munc13, Rim, Bassoon and Piccolo/Aczonin are recently identified presynaptic cytomatrix proteins. These multidomain proteins are thought to organize the exocytotic and endocytotic machinery precisely at active zones.

Active zone assembly and synaptic release

Biochemical Society Transactions, 2006
Neurotransmitter release at chemical synapses occurs when synaptic vesicles fuse to the presynaptic membrane at a specialized site termed the active zone. The depolarization-induced fusion is highly dependent on calcium ions, and, correspondingly, the transmission characteristics of synapses are thought to be influenced by the spatial arrangement of ...

Molecular mechanisms of active zone function

Current Opinion in Neurobiology, 2003
In response to incoming action potentials the presynapse exocytoses neurotransmitter filled vesicles. Proper information encoding requires that the release occurs exactly at the junction to the postsynapse, that it is temporally tightly coupled to the electrical signal and that it proceeds efficiently.

Activity at the active zone

Nature, 2001
The active zones of neurons are characterized in part by protein aggregates that make up 'active-zone material'. The function of this material is unclear, but new high-resolution images look set to change that.

Maintaining the active zone: Demand, supply and disposal of core active zone proteins

Neuroscience Research, 2018
Chemical synapses are sites of cell-cell contact specialized for transmission of signals between neurons and their respective targets. Neurotransmission occurs through the secretion of neurotransmitters at specialized presynaptic membrane regions known as Active Zones (AZs). AZ composition and function are now characterized quite well.
