Low-loss slot waveguides with silicon (111) surfaces realized using anisotropic wet etching [PDF]
, 2016 We demonstrate low-loss slot waveguides on silicon-on-insulator (SOI) platform. Waveguides oriented along the (11-2) direction on the Si (110) plane were first fabricated by a standard e-beam lithography and dry etching process.

Transparent conducting films of CdSe(ZnS) core(shell) quantum dot xerogels [PDF]
, 2012 A method of fabricating sol–gel quantum dot (QD) films is demonstrated, and their optical, structural and electrical properties are evaluated. The CdSe(ZnS) xerogel films remain quantum confined, yet are highly conductive (10−3 S cm−1).

Advanced Functional Materials, Volume 36, Issue 1, 2 January 2026.Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

Metabolic Processes Preserved as Biosignatures in Iron-Oxidizing Microorganisms: Implications for Biosignature Detection on Mars [PDF]
Iron-oxidizing bacteria occupy a distinct environmental niche. These chemolithoautotrophic organisms require very little oxygen (when neutrophilic) or outcompete oxygen for access to Fe(II) (when acidophilic).

Journal of Chromatography A, 1998 A new analytical procedure, tetramethylammonium hydroxide thermochemolysis, was used to structurally characterize a variety of bio-and geo-polymers. The technique cleaves esters and some ethers in macromolecular organic matter, yielding low-molecular-mass monomers such as methyl esters of carboxylic acids and methyl ethers of alcohols that are amenable

Wet‐Chemical Etching of Silicon Wafer Surfaces Using Aqueous HF‐HBrO3 and HF‐HBrO3‐Br2 Solutions
Advanced Materials Interfaces, Volume 13, Issue 2, 20 January 2026.Aqueous mixtures of HF and HBrO3 are reported as a new NOx‐free etching systems for monocrystalline silicon wafers. Silicon is polished with etching rates up to 10 µm min−1 at room temperature. The addition of Br2 leads to anisotropic etching, thus texturing monocrystalline silicon wafer surfaces with upright pyramids.
