High-Speed and High-Responsivity Blue Light Photodetector with an InGaN NR/PEDOT:PSS Heterojunction Decorated with Ag NWs.

InGaN nanorods possessing larger and wavelength selective absorption by regulating In component based visible light photodetectors (PDs) as one of the key components in the field of visible light communication have received widespread attention. Currently, the weak photoelectric conversion efficiency and slow photoresponse speed of InGaN nanorod (NR) based PDs due to high surface states of InGaN NRs impede the actualization of high-responsivity and high-speed blue light PDs. Here, we have demonstrated high-performance InGaN NR/PEDOT:PSS@Ag nanowire (NW) heterojunction blue light photodetectors utilizing surface passivation and a localized surface plasmon resonance effect.

Developing self-regulated learning as a pedagogy in higher education: An institutional survey and case study in Hong Kong.

Self-regulated learning (SRL) is critical to students' academic success and lifelong learning. Although the benefits of SRL have been examined in many studies, few have explored it in a broader educational context. This study presents an eight-month institutional case study that demonstrates how SRL has been developed as a pedagogy through the collective endeavours of teachers, researchers, and experts at a university in Hong Kong.

Promotion of -nitrosation of cysteine by a {Co(NO)} complex.

-Nitrosothiols (SNOs) serve as endogenous carriers and donors of NO within living cells, releasing nitrosonium ions (NO), NO, or other nitroso derivatives. In this study, we present a bioinspired {Co(NO)} complex 1 that achieved -nitrosation towards Cys residues. The incorporation of a ferrocenyl group in 1 allowed for fine-tuning of the nitrosation reaction, taking advantage of the redox ability of Cys residues.

High Performance GaN-Based Ultraviolet Photodetector via Te/Metal Electrodes.

Photodetectors (PDs) based on two-dimensional (2D) materials have promising applications in modern electronics and optoelectronics. However, due to the intralayer recombination of the photogenerated carriers and the inevitable surface trapping stages of the constituent layers, the PDs based on 2D materials usually suffer from low responsivity and poor response speed. In this work, a distinguished GaN-based photodetector is constructed on a sapphire substrate with Te/metal electrodes.

Versatile Synthesis of Symmetric and Unsymmetric Imines via Photoelectrochemical Catalysis: Application to N-Terminal Modification of Phenylalanine.

A strategy that combines electrochemical synthesis and photoredox catalysis was reported for the efficient synthesis of imines. This approach was demonstrated to be highly versatile in producing various types of imines, including symmetric and unsymmetric imines, by exploring the impact of different substituents on the benzene ring of the arylamine. Additionally, the method was specifically applied to modify N-terminal phenylalanine residues and was found to be successful in the photoelectrochemical cross-coupling reaction between NH -Phe-OMe and aryl methylamines, leading to the synthesis of phenylalanine-containing imines.

High-speed graphene/InGaN heterojunction photodetectors for potential application in visible light communication.

Due to the wavelength-selective absorption characteristic of indium gallium nitride (InGaN) ternary alloy, the InGaN-based photodetectors (PDs) show great potential as high signal-to-noise ratio (SNR) receivers in the visible light communication (VLC) system. However, the application of InGaN-based PDs with simple structure in the VLC system is limited by slow speed. Integration of graphene (Gr) with InGaN is an effective strategy for overcoming the limitation.

Defect-Rich Heterogeneous MoS/rGO/NiS Nanocomposite for Efficient pH-Universal Hydrogen Evolution.

Molybdenum disulfide (MoS) has been universally demonstrated to be an effective electrocatalytic catalyst for hydrogen evolution reaction (HER). However, the low conductivity, few active sites and poor stability of MoS-based electrocatalysts hinder its hydrogen evolution performance in a wide pH range. The introduction of other metal phases and carbon materials can create rich interfaces and defects to enhance the activity and stability of the catalyst.
