Disclosed is a media for capturing carbon dioxide from a gas stream of ambient air or industrial exhaust. The media includes a fiber matrix having fine fiber strands formed from at least one first polymer capable of capturing carbon dioxide through absorbance or adsorbance. The fine fiber strands have a first mean diameter of 5000 nm or less. Further, the media includes a plurality of nodules dispersed in the fiber matrix, and the plurality of nodules are made from a nodule material capable of capturing carbon dioxide through absorbance or adsorbance. The media can be configured for use in a carbon capture element of a carbon capture cell disposed within a carbon capture system, such as a direct air or point source carbon capture system.

The invention provides a preparation method of composite aerogel, the composite aerogel, a thermal management system and a battery, and relates to the technical field of batteries. According to the specific technical scheme, fiber gel and organic sol are provided, wherein the fiber gel comprises silicon-based gel and a fiber matrix; coating the organic sol on the outer surface of the fiber gel body to obtain a composite gel body; drying the composite gel to obtain a composite material, forming silicon-based aerogel from the silicon-based gel, and forming fiber aerogel from the fiber gel; finally, carbonizing the composite material to obtain composite aerogel, and forming carbon aerogel from the organic sol; the composite aerogel prepared by the method not only has synergistic heat insulation and heat conduction functions, but also has a relatively stable structure, and can be applied to a battery as a thermal protection material so as to improve the overall safety of the battery.

The fibrous matrix may comprise glass fibers, polyolefin fibers, polyvinylidene fluoride (PVDF) fibers, polytetrafluoroethylene (PTFE) fibers, polypropylene fibers, polyethylene fibers, aramid fibers, natural cellulosic fibers, or a combination thereof. A composition comprising the medium is provided. A device comprising the medium or the composition is also provided. Further provided are methods for preparing a proteomic sample from a biological sample on the medium. The biological sample comprises cells or proteins. The method may comprise a treating step, a digesting step, a reducing and alkylating step, and an eluting step. All of these steps may be performed on the medium. The proteomic sample comprises the eluted peptides. The proteomic sample may be desalted. The peptides prepared from the biological sample may be suitable for qualitative or quantitative analysis, for example, mass spectrometric analysis.

The invention relates to a method for producing a fibrous web containing natural and synthetic fibers. The invention relates to a method for producing a fibrous web comprising a fibrous matrix consisting of natural fibers and possibly synthetic fibers. According to the method of the invention, a layer containing horizontal plane fibers is prepared from natural fibers and possibly synthetic fibers, the layer comprising an aqueous phase and a fiber phase, and the layer is dried to remove the aqueous phase, in which case the natural fibers and possibly synthetic fibers together form a fiber matrix. According to the invention, a binder is applied to the aqueous fibrous layer such that the binder at least partially permeates through the aqueous phase between the fibres before hydrogen bonds are formed between the fibres. Using the invention, such cellulose-or lignocellulose-based fibrous products having plastic-like properties such as good fracture toughness, tear resistance and stretch can be produced.
