Abstract: An object is to provide a dehumidifying member having a high tensile strength. The object can be achieved by a dehumidifying member including a honeycomb structure. The honeycomb structure includes a planar base material and a corrugated base material, a contact part where a wave top portion of the corrugated base material and the planar base material are in contact with each other, and an air hole. The contact part includes an adhesion part adhered by an adhesive agent and silica gel formed on the air hole side from the contact part. The component forming the adhesive agent differs from the component of the silica gel formed on the air hole side from the adhesion part.

Abstract: The invention relates to a process for preparing core-shell particles comprising the steps of (i) providing a dispersion of primary magnetic particles having a mean diameter lower than 200 nm in a solvent; (ii) adding one or more (semi-)metal (oxyhydr)oxide(s) and/or one or more precursor(s) of a (semi-)metal (oxyhydr)oxide to said dispersion; (iii) optionally adding a hydrolysis agent for said one or more precursor(s); (iv) injecting the dispersion in a spray dryer; whereby a (semi-)metal (oxyhydr)oxide shell is formed on the magnetic particles during spray drying. The invention also relates to particles obtainable by said process, to a formulation of said particles in a solvent and to the use of said particles or said formulation for RNA or DNA extraction.

Abstract: Many embodiments described herein prevent an aged spirit from degrading due to the oxygen trapped in the headspace without the use of a pump. The aged spirit preservation system may have a cork with an open top, an open bottom, and a channel extending from the open top to the open bottom. The cork may be sized couple to an internal portion of a bottle. The system may even include a sealing device coupled to an outer portion of the cork between the open top and the open bottom. Additionally, the system may include a replaceable cartridge containing an adsorbent media, iron, a salt, and a color-changing indicator. Oxygen from the bottle may be allowed to enter the cartridge and react with the iron via a non-reversible reaction, thereby preventing the degradation of the spirit.

Abstract: Provided is a high-loading and alkali-resistant protein A magnetic bead. The magnetic bead can maintain chemical stability under pH 2-14 and has an immunoglobulin G (IgG) binding capacity greater than 50 mg/mL. Further provided is a method for purifying and/or detecting an immunoglobulin, comprising a step of contacting a sample containing the immunoglobulin with the high-loading and alkali-resistant protein A magnetic bead. The alkali-resistant protein A magnetic bead can realize rapid purification of immunoglobulin, saving about 80% of treatment time and reducing total purification costs by 50%. In addition, the alkali-resistant protein A magnetic bead has high alkali resistance. An alkaline method for in situ cleaning can be performed to regenerate the magnetic bead after use. The magnetic bead has rapid magnetic response and good dispersiveness, realizing rapid magnetic bead enrichment, cleaning, and elution. The magnetic bead facilitates automated, high-throughput, and large volume purification of a sample.
