The increasing power density of high-performance electronic devices poses significant thermal management challenges. Vapor chambers (VCs) offer efficient heat dissipation, but traditional manufacturing methods limit their structural precision and performance. This study investigates the thermal performance of VCs fabricated with additive manufacturing (AM), featuring triply periodic minimal surface (TPMS) Gyroid capillary structures at two fill ratios under varying thermal loads.

Semitransparent perovskite solar cells (ST-PSCs) for tandem applications typically use a buffer layer deposited via atomic layer deposition (ALD) to protect the cell stack from the damage induced by the sputtering of the transparent electrode. Here, we present a simple yet effective solution-processed buffer layer based on metal-oxide nanoparticles to mitigate sputter-induced damage. We exploit this strategy in a monolithic tandem integrating the optimized ST-PSC on a polished front-side/unpolished rear-side -type silicon heterojunction (SHJ) solar cell.

Although the Asian American, Native Hawaiian, and Pacific Islander (AANHPI) population encompasses more than 50 ethnicities and 100 languages, it is often treated as a monolith in research and policy. Despite substantial heterogeneity, policy makers and researchers do not usually focus on AANHPI subgroups when discussing underrepresentation and health disparities. We provide insights on the representation of AANHPI populations by disaggregating the AANHPI racial category among the health workforce and examining the representation of AANHPI subgroups in health occupations.

Ectodermal dysplasia, a disorder inherited through an X-linked recessive trait, is characterized by abnormalities in two or more structures that originate in the ectoderm. Dental manifestations include missing or malformed teeth. This clinical report details 16 years of interdisciplinary management, starting at age 7 and concluding after skeletal maturation, for a patient with ectodermal dysplasia.

The growing heat flow density from the miniaturization trend of electronic devices seriously challenges the heat diffusion in electronic systems. Consequently, there is an increasing demand for thermal management materials with both thermal conductivity (K) and material thickness (d) to effectively transfer devices' heat flux. Graphene films (GFs) with high K have attracted significant attention, but achieving both high K and large d remains challenging due to graphene's intrinsic properties and fabrication limitations.
