Electrocatalysts with high activity and durability for acidic oxygen evolution reaction (OER) play a crucial role in achieving cost‐effective hydrogen production via proton exchange membrane water electrolysis. A novel electrocatalyst, Te‐doped RuO2 (Te–RuO2) nanotubes, synthesized using a template‐directed process, which significantly enhances the OER performance in acidic media is reported. The...
Conventional two‐dimensional electron gas (2DEG) typically occurs at the interface of semiconductor heterostructures and noble metal surfaces, but it is scarcely observed in individual 2D semiconductors. In this study, few‐layer gallium selenide (GaSe) grown on highly ordered pyrolytic graphite (HOPG) is demonstrated using scanning tunneling microscopy and spectroscopy (STM/STS), revealing that the...
Controllable modulation of the stacking modes of 2D (two‐dimensional) materials can significantly influence their properties and functionalities but remains a formidable synthetic challenge. Here, an effective strategy is proposed to control the layer stacking of imide‐linked 2D covalent organic frameworks (COFs) by altering the synthetic methods. Specifically, a modulator‐assisted method can afford...
2D van der Waals heterojunction provides an attractive opportunity for realizing novel electronic or optoelectronic devices. It remains challenging to realize high‐quality heterostructures through scalable methods such as molecular epitaxy growth (MBE). Here, growth of few‐layer SnS thin films is reported on mica and Nb‐doped SrTiO3(100) substrates by MBE. Then the top layer of SnS film is uniformly...
Metal–organic frameworks (MOFs) are constructed by periodically alternate metal ions with organic ligands, which offer structural diversity and a wide range of interesting properties as an attractive classification of crystalline porous materials. Integration of MOFs with other size‐limited functional centers can supply new multifunctional composites, which exhibit both the properties of the components...
Zeolitic imidazolate framework‐8 (ZIF‐8)‐derived N‐doped graphene analogous polyhedrons (ZNGs) obtained via the direct carbonation of ZIF‐8 are applied to photocatalytic hydrogen evolution for the first time. The contents of different types of nitrogen atoms in ZNGs can be fine‐tuned via the calcination temperature, which significantly influences the hydrogen evolution rate of the ZNGs.
Antiamyloidogenic agents have promising application potential in AD therapies. In article number 1602857, L. Zhu, Z. Hu, Y. Yang, and co‐workers present an Aβ42‐binding agent amyloid inhibitory 1 (AIP1), demonstrate its inhibitory effect on Aβ42 oligomerization and fibrillation, and show that AIP1 rescue Aβ42‐induced cytotoxicity through decreasing Aβ42 oligomer content is related to cell membrane...
The oligomerization and aggregation of amyloid β (Aβ) play central role in the pathogenesis of Alzheimer's disease (AD). Molecular binding agents for modulating the formation of Aβ oligomers and fibrils have promising application potential in AD therapies. By screening a peptoid library using surface plasmon resonance imaging, amyloid inhibitory peptoid 1 (AIP1) that has high affinity to Aβ42 is identified...
Beam pen lithography (BPL) in the liquid phase is evaluated. The effect of tip‐substrate gap and aperture size on patterning performance is systematically investigated. As a proof‐of‐concept experiment, nanoarrays of nucleotides are synthesized using BPL in an organic medium, pointing toward the potential of using liquid phase BPL to perform localized photochemical reactions that require a liquid...
