AI Article Synopsis
Article Abstract
Gallium was administered subcutaneously to mice, and was found to be localized essentially in the skeleton. It was measured in the bones of animals given daily injections of gallium sulfate. There was little or no mortality. The amount of gallium found rose with the number of injections, and was greater when higher doses were injected. Elimination was very low after cessation of treatment. Results were used to study the action of gallium on cutaneous allografts in mice.

Thick metamorphic buffers are considered indispensable for III-V semiconductor heteroepitaxy on large lattice and thermal-expansion mismatched silicon substrates. However, III-nitride buffers in conventional GaN-on-Si high electron mobility transistors (HEMT) impose a substantial thermal resistance, deteriorating device efficiency and lifetime by throttling heat extraction. To circumvent this, a systematic methodology for the direct growth of GaN after the AlN nucleation layer on six-inch silicon substrates is demonstrated using metal-organic vapor phase epitaxy (MOVPE).

Antimicrobial resistance and impaired bone regeneration are the great challenges in treating infected bone defects. Its recurrent and resistant nature, high incidence rate, long-term hospitalization, and high medical costs have driven the efforts of the scientific community to develop new therapies to improve the situation. Considering the complex microenvironment and persistent mechanisms mediated by resistant bacteria, it is crucial to develop an implant with enhanced osseointegration and sustained and effective infection clearance effects.

Enhancing the wettability of liquid metals (LMs) to address their high surface tensions is crucial for practical applications. However, controlling LMs wetting on various substrates and understanding the underlying mechanisms are challenging. Here, we present a facile dynamic-wetting strategy to modulate eutectic gallium-indium (EGaIn) wettability via chemical surface modification, spontaneously forming a stable and thin (∼18 μm) EGaIn layer.

Point of Care (POC) diagnosis provides an effective approach for controlling and managing Neglected Tropical Diseases (NTDs). Electrochemical biosensors are well-suited for molecular diagnostics due to their high sensitivity, cost-effectiveness, and ease of integration into POC devices. Schistosomiasis is a prominent NTD highly prevalent in Africa, Asia, and Latin America, with significant socioeconomic implications such as discrimination, reduced work capacity, or mortality, perpetuating the cycle of poverty in affected regions worldwide.

State Key Laboratory of Superlattices and Microstructures, Institute of Semiconductors, Chinese Academy of Sciences, Beijing, 100083, China.
Ultraviolet light detection is essential for environmental monitoring, hazard alerting, and optical communication. Here, a vertical UV photodetector is proposed and demonstrated by stacking the freestanding GaN-film on the 2D GaSe flake. Benefits from the vertical heterostructure and built-in electric field, the photodetector exhibits excellent photoresponse properties, including a high responsivity of 1.
