The invention relates to an autonomously curable and foamable two-component acrylic adhesive that upon combining the two components with one another spontaneously foams and cures thereby forming a cured foamed acrylic adhesive. The cured foamed acrylic adhesive may have utility as structural adhesive, sealant, noise dampening material and the like. The cured foamed acrylic adhesive is particularly useful for structural reinforcement within cavities of structural elements, e.g. of automotive vehicles, aircrafts, railway carriers, or other means of transportation.

Disclosed herein is a transparent photothermal composition, which includes nonstoichiometric copper sulfide (Cu.sub.2-xS, 0<x1) nanoparticles dispersed in an acrylic resin, wherein the Cu.sub.2-xS (0<x1) nanoparticles are nanorods independently having an aspect ratio ranged from 2.2 to 3.6 and exhibit at least 95% absorption of a near-infrared (NIR) light ranged from 800 to 1,100 nm. Also disclosed herein are methods of producing the transparent photothermal composition and uses of the transparent photothermal composition in protecting a glass substrate from icing in a cold surrounding.

Microspheres refer to micro-particle dispersion systems formed by pharmaceutical molecules dispersed or adsorbed in polymer carriers such as albumin, gelatin and polylactide; and their particle sizes are different from microns to hundreds of microns.

The present disclosure relates to a super absorbent polymer film and a preparation method of the same. Specifically, it relates to a new type of super absorbent polymer film, which is thin and exhibits excellent absorption performance, flexibility and elasticity while having little change in the shape of products. In addition, the super absorbent polymer film of the present disclosure is free from scattering or leaking, and does not require an auxiliary substance such as pulp, so that products can be made thinner and the manufacturing process and costs may be reduced.

The present disclosure provides systems and methods for making a hydrogel comprising a cell, cell nucleus, or one or more components derived from a cell or cell nucleus. A method for making a hydrogel may comprise providing a cell or cell nucleus, a first polymer, wherein the first polymer comprises a plurality of first crosslink precursors, each of the plurality of first crosslink precursors comprising an azide group; providing a second polymer, wherein the second polymer comprises a plurality of second crosslink precursors, each of the plurality of second crosslink precursors comprising an alkyne group; and crosslinking the first polymer and the second polymer via a reaction between a first section of the first crosslink precursors and a second section of the second crosslink precursors, thereby providing the hydrogel comprising the cell or cell nucleus.
