Summary: The introduction of avalanche photodetectors in optical interconnects can extend the unallocated optical budget and provide opportunities for novel datacenter network architectures. By harvesting the dropped power during optical modulation, a specialized high-voltage bias circuit for photodiodes can be avoided. Instead, a photovoltaic power conversion circuit is used to convert the collected light into a high-voltage bias shared among all data lanes of the optical interconnect.

Summary: This study demonstrates the modulation of luminous color in low-concentration Yb/Er/Tm-codoped UCNPs through manipulation of laser power or pulse parameters. The role of Tm(3+) species as the red-emission-associated transient energy trapping center can be attenuated by Yb3+-mediated laser-power-dependent sensitization processes. The unique feature of dual-mode luminous color modulation enables high-level anticounterfeiting applications in specific scenarios.

Summary: The growing demand for faster data transference and communication has led to the development of faster and more efficient communication network-based technologies, such as wireless systems and visible light communication (VLC) processes. The use of light converters, such as phosphor materials, can efficiently convert blue light into different colors for higher bandwidth values and faster data/information transmission. Recent advances in luminescent materials, including polymers, organic molecules, and semiconductor nanocrystals, have improved the photophysical properties and carrier recombination dynamics, offering enhanced VLC process for efficient optical communication applications.

Summary: To achieve efficient photoecological effect and control the cost of light conversion agent, three carbazole derivatives as donors and a tris(carbazolyl) substituted triazine as an acceptor were designed and synthesized. The best formulation of light conversion films, TCZ@0.2TPT@EVAb and MCZ@0.2TPT@EVAb films, show high photosynthetic photon flux density and fluorescence emission. These doping films demonstrate excellent photostability, compatibility, and dispersion of the light conversion agent, and exhibit promising UV light conversion properties.

Summary: Fixation of nitrogen using renewable energy has recently gained much attention. However, its performance is limited by the hydrogen evolution reaction (HER) competition and the difficulty in activating N-2. In this study, a new strategy of incorporating Pd into the HKUST-1 framework was proposed to enhance the electrochemical nitrogen reduction reaction (NRR) activity. The Pd/HKUST-1 catalyst, obtained through thermal treatment, exhibited high ammonia production rate and stability.

Summary: In this experiment, the effects of different heat treatment pressures on the equilibrium moisture content, dimensional stability, mechanical properties, and chemical composition of bamboo were investigated. The results showed that the equilibrium moisture content of heat-treated bamboo decreases with increasing treatment pressure, while the dimensional stability increases. The optimal heat treatment pressure for bamboo is 0.1 MPa, which significantly improves the bending strength and longitudinal compressive strength compared to the control group. Various physical and chemical transformations were observed during the heat treatment process.
