Multi‐Dielectric Metasurfaces for Ultrabright, Tunable Structural Color and Reconfigurable Optical Filtering with Extraordinarily Large Color Span

open access: yesAdvanced Optical Materials, Volume 14, Issue 23, 19 June 2026.
Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.

Fabrication of High‐Density Multimodal Neural Probes Based on Heterogeneously Integrated CMOS

open access: yesAdvanced Science, Volume 13, Issue 34, 19 June 2026.
A chiplet‐based methodology democratizes active neural probe development on standard bulk CMOS services. This yields the first probe combining high‐density electrophysiology (416 electrodes) with calcium imaging (832 photodiodes) and complete on‐chip signal processing across 13 shanks.

Drivers of Greenhouse Gas Emissions in Tropical Riverine Systems Across a Gradient of Human Impact

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Tropical lotic ecosystems are important sources of greenhouse gas emissions, yet the magnitude and variability of such emissions remain poorly constrained. Here, we quantified spatial and short‐term temporal variability of carbon dioxide (CO2) and methane (CH4) fluxes across tropical riverine systems spanning a gradient of human impact, while ...

SF6的温度与湿度及其对产品绝缘性能的影响

open access: yesGaoya dianqi, 2010
选用三台新组装的LW8-40.5罐式SF6断路器进行试验,研究环境温度与SF6湿度的关系以及对产品绝缘性能的影响,得出,当SF6相对湿度RH值约为30%时,产品耐受高电压能力未发现明显变化;在考虑SF6湿度测量值的近似温度折算方法时,可用适当方式来利用克劳修斯-克拉贝龙方程,按低于30%的某个RH值制定SF6湿度的限值标准,能排除温度的影响,简单可行,便于实施SF6湿度的在线监测。

Impact of Ions and Radicals on Etch Selectivity and Fluorocarbon Polymerization in the Selective Dry Etching of Si0.7Ge0.3

open access: yesPlasma Processes and Polymers, Volume 23, Issue 6, June 2026.
Ion screening in CF4 plasma reduces CFx+ ion flux while maintaining radical fluxes, suppressing fluorocarbon polymer accumulation. This enables smooth SiGe etching with selectivity up to 30:1 in multilayer stacks. ABSTRACT Selective etching of Si0.7Ge0.3 was investigated in CF4 inductively coupled plasma using an ion‐screening approach to decouple ion ...

Molecular Behavior of Binary SF6-H2 Hydrate

open access: yes, 2012
DoctorSulfur hexafluoride (SF6), one of the most potent greenhouse gases, is known as a hydrate former and has been studied at the high pressure up to 1.3 GPa with gas mixtures and with aqueous surfactant.

Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit

open access: yesSmall, Volume 22, Issue 32, 8 June 2026.
An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis

open access: yesActa Ophthalmologica, Volume 104, Issue 4, Page 410-422, June 2026.
Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).
