11596913 · 2023-03-07 · ·

Methods of high throughput hydrocolloid bead production and related apparatuses are described herein. In the disclosed methods, drops of a hydrocolloid gel suspension are dropped into a reactant bath. The drops of hydrocolloid gel are exposed to the reactant bath for a predetermined period of time, during which the drops form firm or semi-firm beads. The beads are then removed from the reactant bath. The resulting hydrocolloid beads are advantageously resistant to syneresis and can provide high nutritional and water content.

Urea-functionalized sol-gel

Urea and amine comprising sol-gel hybrid coatings have been developed for numerous applications, including capillary microextraction-high performance liquid chromatographic analysis from aqueous samples. A fused silica capillary may be coated from the inside with surface bonded coating material and may be created by in-situ sol-gel reaction(s). Urea-functionalized coatings can be immobilized on the inner surface of a capillary by condensing silanol groups of capillary and sol-solution. Urea functionalized, sol-gel coated capillaries may be installed, e.g., in HPLC manual injection ports, and optionally pre-concentrated analytes including phenols, ketones, aldehydes, and/or polyaromatic hydrocarbons, from highly polar to non-polar, maybe analyzed by online extraction and high-performance liquid chromatographic. Such coatings may achieve sensitivities with lower detection limits (S/N=3) of 0.10 ng/mL to 14.29 ng/mL, with reproducibilities of <12.0% RSD (n=3), or <10.0% RSD (n=3) by exchanging the capillary of the same size.

Preparation of graphene oxide aerogel beads and applications thereof

Graphene oxide aerogel beads (GOABs) are formed that have a core/shell structure where a smooth shell covers a multi-layer core. The smooth shell and the layers of the multilayer core comprise graphene oxide or reduced graphene oxide. The GOABs can include a phase-change material encapsulated within the multi-layer core. The GOABs can be combined or decorated with Fe.sub.3O.sub.4 nanoparticles or MoS.sub.2 microflakes for various applications. The GOABs are formed from aqueous slurries of graphene oxide that is extruded as drops into an aqueous solution of a coagulant where GOABs are formed. The GOABs are washed and freeze dried, after which, the GOABs can be reduced as desired by chemical or thermal means. Impregnation can be carried out with the phase-change material.
