The present invention provides a novel method to fabricate silica nanostructures on thin polymer films based on silica deposition and self-wrinkling induced by thermal shrinkage. These micro- and nano-scale structures have vastly enlarged the specific area of silica, thus the silica nanomembranes can be used for solid phase extraction of nucleic acids. The inventive silica nanomembranes are suitable for nucleic acid purification and isolation and demonstrated better performance than commercial particles in terms of DNA recovery yield and integrity. In addition, the silica nanomembranes have extremely high nucleic acid capacity due to its significantly enlarged specific surface area of silica. Methods of use and devices comprising the silica nanomembranes are also provided.

The present invention relates to a composition for modulating tumor cell dissemination, in particular metastatic cancer cells. In particular, the invention relates to an agent for modulating metastatic tumor cell dissemination for use in the treatment and/or prevention of a metastatic cancer wherein the agent an extracellular matrix (ECM) protein carried on a polycarbonate polyurethane matrix. The invention also relates to a product, comprising an agent for modulating metastatic tumor cell dissemination, and to a method of treatment or prevention of cancer.

A method is provided for managing microporous and/or mesoporous and/or macroporous small particle adsorbent powders within a manufacturing process to minimize atmospheric dust. The adsorbent powder is processed by spray-drying to form larger diameter spherical particles. The larger diameter spherical particles are then dispersed in a controlled manner so as to be brought into intimate contact with a substrate. The resultant powder-and-substrate matrix is then subjected to an alternating electrical field (AEF) via an alternating power supply, thereby to reduce the spray-dried powder back to its original small particle state, whilst remaining in intimate contact with the substrate.

The present invention relates to methods for synthesizing MFI zeolite nanosheet (ZN) assemblies and open-pore ZN plates and for tiling ZN plates on polymer supports. Methods for producing ZN assemblies and ZN plates may reduce or eliminate the need to synthesize nanoparticle (NP) seed-evolved single-crystal zeolite nanosheets (ZNs) as an intermediate product. Methods for tiling ZN plates on polymer supports may produce ZN plate-tiled (ZNPT) membranes with reduced permeation through intercrystalline spaces.

The present invention relates to layered multi-metal-oxide-based magnetic biochar and a preparation method and use thereof. The preparation method includes: S1. mixing biomass and an iron salt solution for impregnation, and then adjusting a first pH value of a solid phase material after solid-liquid separation to obtain pretreated biomass; and S2. pyrolyzing the pretreated biomass to obtain magnetic biochar, then mixing the magnetic biochar with a solution containing at least two metal salts and adjusting a second pH value, and then performing hydrothermal treatment to obtain the layered multi-metal-oxide-based magnetic biochar. The obtained layered multi-metal-oxide-based magnetic biochar has a large specific surface area, magnetic properties, a layered morphology, and strong adsorption capacity, and can be applied to the treatment of arsenic- and cadmium-containing composite contaminated water bodies, and also to arsenic and cadmium passivation in farmland soil, thereby reducing health risks of crops in the food chains, and ensuring food safety.

The invention relates to a hydrophobically coated molecular sieve which comprises particles having a particle size of 1000 nm or less, the surface of the particles being coated with a silane of the general formula SiR.sup.1R.sup.2R.sup.3R.sup.4, and also to a method of producing it and to a method of using it. In addition, the invention relates to use of the coated molecular sieve and also to compositions comprising the molecular sieve and to use in producing apparatus such as, for example, electronic components and devices.

The invention describes a mass for scavenging mercaptans which is particularly suitable for the treatment of olefinic gasoline cuts containing sulfur such as gasolines resulting from catalytic cracking. The scavenging mass comprises an active phase based on group VIII, IB or IIB metal particles which is prepared by a step of bringing a porous support into contact with a metal salt of said group VIII, IB or IIB metal and a step heating the resulting mixture to a temperature above the melting point of said metal salt. The invention also relates to a process for using said scavenging mass for the adsorption of mercaptans.
