An amphiphile (from the Greek αμφις, amphis: both and φιλíα, philia: love, friendship) is a chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving) properties. Such a compound is called amphiphilic or amphipathic. This forms the basis for a number of areas of research in chemistry and biochemistry, notably that of lipid polymorphism. Organic compounds containing hydrophilic groups at both ends of a prolate (in the aggregate) molecule are called bolaamphiphilic. Common amphiphilic substances are soaps, detergents and lipoproteins.
Wedge-shaped amphiphiles, biomimetic ion-conducting membranes, and methods of making the same
This invention relates to the field of ion-conducting membrane technology, and particularly to a wedge-shaped amphiphilic molecule, a biomimetic ion-conducting membrane, and its preparation method. The biomimetic ion-conducting membrane utilizes the self-assembly behavior of the wedge-shaped amphiphilic molecule to form a columnar mesocrystalline phase containing transport channels. This columnar structure is fixed within a membrane framework composed of methacrylate polymers using ultraviolet graft copolymerization to form an ion-transfer membrane. This membrane exhibits strong ion selectivity and conductivity, and its mechanism of action is similar to that of biological cell membranes. It can be used for the transport and separation of microparticle materials such as ions, small molecules, and micro-electronic conductors, showing broad application prospects in fields such as biology, medicine, and environmental analysis. Furthermore, its ion conductivity and chemical stability also demonstrate its potential application in proton exchange membrane fuel cells.

A method for preparing a floating composite reagent by using a biomass hydrothermal liquefaction product
This invention discloses a method for preparing a composite flotation reagent using biomass hydrothermal liquefaction products, comprising the following steps: Raw material preparation: providing biomass raw materials rich in lipids or proteins; Catalytic hydrothermal liquefaction: placing the biomass raw materials and a composite catalyst in a reactor, reacting at a temperature of 250-350℃ and a pressure of 4-20 MPa, wherein the water content of the biomass raw materials is 70-95%, and the composite catalyst contains alkaline components, metal oxide components, and rare earth element components; Product separation: separating the reaction products into oil and water to obtain bio-crude oil containing amphiphilic molecules; Flotation application: applying the bio-crude oil as a composite flotation reagent to mineral flotation, where the bio-crude oil simultaneously functions as a frother and a collector. This invention uses waste biomass as raw material to prepare a composite flotation reagent with both frother and collector functions, realizing the resource utilization of waste and the green upgrading of flotation reagents, and has the characteristics of wide raw material sources, excellent reagent performance, and environmental friendliness.
