Abstract: A silicon-based solid amine sorbent for CO2 and the making method thereof including: providing a silicon source liquid which is a silicate solution or a liquid organosilicate, wherein the silicate solution comprises water and a first silicate dissolved in the water; mixing the silicon source liquid with a precipitant to perform a precipitation reaction to obtain a product liquid containing a precipitate, wherein the precipitate is a second silicate or silicic acid; filtering out the precipitate and washing the precipitate with water; mixing the precipitate filtrated out but not dried yet with an organic alcohol and then performing an azeotropic distillation to obtain a dehydrated precipitate; calcining the dehydrated precipitate to obtain a silicon-based support, wherein the silicon-based support is a powder of the second silicate powder or a silica powder; and impregnating the silicon-based support with an organic amine solution and then drying to obtain the silicon-based amine-containing solid sorbent for C

Abstract: A porous calcium silicate hydrate, a preparation method thereof and an adsorbent are provided. The preparation method of the porous calcium silicate hydrate includes: leaching fly ash with an alkali agent to obtain a silicate leaching solution; adding the silicate leaching solution dropwise to a calcium hydroxide suspension at a constant rate, and conducting stirring and a heating reaction to obtain a calcium silicate hydrate gel; and mixing the calcium silicate hydrate gel with an organic alcohol solvent, conducting azeotropic distillation, and then conducting separation, drying and calcination to obtain the porous calcium silicate hydrate.

Abstract: A method and system for concentrating an analyte (A). Liquid droplets (D) of an extractant liquid (Le) are adhered to a wall (10w) of a container, e.g. capillary tube. A sample fluid (Fs) comprising the analyte (A) is provided in the container (10) to contact the liquid droplets (D). The analyte (A) has a higher solubility in the liquid droplets (D) than in the sample fluid (Fs). This causes the analyte (A) to be extracted from the sample fluid (Fs) and concentrated in the liquid droplets (D). After extraction, the liquid droplets (D) are collected, e.g. scraped, from the wall (10w) for obtaining the concentrated analyte (A). A concentrated liquid (La) can be formed by collecting the liquid droplets (D) from the wall (10w). The analyte (A) can be measured in the concentrated liquid (La) using any suitable measurement technique.

Abstract: A motor component, a motor and a motor vehicle are disclosed. The motor component has a body extending along a rotation axis of the motor, the body being formed by a set of laminations, and an axially extending cavity being provided on the body; and wherein at least one elongated lamination-holding component is provided in the body, and the lamination-holding component is inserted into the axially extending cavity and is coupled to the body inside the axially extending cavity.

Abstract: Provided herein is a transgenic plant having increased expression of a coding region encoding a resistance protein, where the transgenic plant has increased resistance to infection by Leptosphaeria maculans. In one embodiment, the transgenic plant is B. napus, B. oleraceae, B. rapa, or B. juncea. Also provided are methods of increasing resistance of a member of the genus Brassica to infection by Leptosphaeria maculans, methods of making a transgenic plant with increased resistance to Leptosphaeria maculans, and methods of producing food, feed, or an industrial product using a transgenic plant.
