Near- and supercritical water (SCW) has recently been shown to provide an unusual but effective tool to roughen the inner surface or manipulate the internal diameter of fused silica capillaries for analytical separation methods In this review, the to-date existing variants of instrumental arrangement for etching the fused silica capillaries with SCW are described, the currently accessible morphologies of SCW-etched capillaries are outlined, and both existing and prospective applications of the SCW-etched capillaries in analytical separations are briefly discussed. Relative merits of SCW and other agents to treat the inner surfaces of fused silica capillaries are also mentioned.

Background: Benzodiazepine abuse remains a significant public health concern. Current sample preparation methods for benzodiazepine analysis from human serum often involve complex procedures that require large sample volumes and extensive organic solvent use. To address these limitations, this study presents a novel and efficient sample preparation method utilizing 3D-printed sorbent devices.

In this study, new monolithic poly(9-anthracenylmethyl methacrylate-co-trimethylolpropane trimethacrylate (TRIM) columns, referred as ANM monoliths were prepared, for the first time, and were used for the separation media for biomolecules and proteomics analysis by nano-liquid chromatography (nano-LC). Monolithic columns were prepared by in situ polymerization of 9-anthracenylmethyl methacrylate (ANM) and trimethylolpropane trimethacrylate (TRIM) in a fused silica capillary column of 100 µm ID. Polymerization solution was optimized in relation to monomer and porogenic solvent.

Black aluminum is a material characterized by high surface porosity due to columnar growth and exhibits unique optical properties that make it attractive for applications such as light trapping, infrared detection, and passive thermal radiation cooling. In this study, we correlate the structural and optical properties of black aluminum by comparing it with conventional reflective aluminum layers. These layers of varying thicknesses were deposited on fused silica substrates, and their optical properties were analyzed.

An analytical method for identifying the chemical constituents in the Chinese herbal combination Jiuwei decoction was established using capillary electrophoresis coupled with quadrupole time-of-flight mass spectrometry. Nine herbs were extracted with a 60:40 (v/v) ethanol/water solution to prepare the Jiuwei decoction. Electrophoretic separation was carried out using a 50 µm i.
