A device, system, and method for removing a component from a gas are disclosed. A bead consisting of a core and an outer layer is provided. The outer layer consists of a first impermeable material. The core consists of a second material. A carrier gas, containing a vapor, is passed across the bead, desublimating or desublimating and condensing a portion of the vapor onto the bead.

A lithium ion sorbent includes an organosilane-grafted lithium ion sieve. The organosilane-grafted lithium ion sieve is a reaction product of a lithium ion sieve and an organosilane. The lithium ion sieve is either a delithiated orthosilicate or a delithiated metal oxide. The organosilane reagent is of the general formula: R.sup.1—(CH.sub.2).sub.n—Si—R.sup.4.sub.3 where R.sup.1 is an organic moiety containing a functional group selected from an acrylate, methacrylate or vinyl group or their derivatives, R.sup.4 is either a hydrolysable alkoxy group or a methyl group, where at least one of the three R.sup.4 groups is a hydrolysable alkoxy group and n is 1-3. This lithium ion sorbent is durable and useful for adsorbing lithium from aqueous resources. The lithium ion sorbent can also be used in the manufacture of a composite material where the organosilane-grafted lithium ion sieve is covalently incorporated into a porous crosslinked polymeric support scaffold.

An organic light emitting display device may include a filling part filling a space between a second substrate and an organic light emitting diode, and a dam structure disposed in a non-display area and surrounding the filling part. At least one of the dam structure and the filling part includes a getter. The getter of the present disclosure is composed of magnesium oxide particles whose surfaces are modified into a first surface modification part made of an amino silane-based compound and a second surface modification part bound to the first surface modification part and made of a compound containing an acrylate group and a methacrylate group. Accordingly, it is possible to provide an organic light emitting display device that has high transparency and of which optical properties and durability are improved by minimizing permeation of water and oxygen.

The present disclosure provides a fast and high-capacity intelligent cellulose-based oil-absorbing material and a preparation method and use thereof. The material includes an intelligent response layer and an adsorption layer. The intelligent response layer is a pH-responsive nanofiber layer with an adjustable pH response performance and is obtained by grafting hyperbranched polycarboxylic acid-modified polyethyleneimine on to carboxylated cellulose nanofibers. The hyperbranched polycarboxylic acid is prepared by melting and polycondensing at a high temperature, using trimethylolpropane as a core, citric acid as a reactive monomer, and p-toluenesulfonic acid as a catalyst. The adsorption layer is prepared by coating ferroferric oxide with the carboxylated cellulose nanofibers to prepare magnetic carboxylated cellulose nanofibers, and then modifying the magnetic carboxylated cellulose nanofibers with hexadecylamine.
