An improved technology for inactivation of viruses, for example the SARS-CoV-2 virus that is causing the Covid-19 pandemic, is described. The technology can include a device that includes a substrate coated in a polymer that is infused with a pathogen inactivating material. In various embodiments, at a given time, a portion of the pathogen inactivating material is exposed to the environment, and the device is configured to periodically or intermittently expose additional pathogen inactivating material to the environment. For example, the polymer can be ablative or sacrificial.

A blood isolation and extraction method includes: providing a predetermined amount of blood; utilizing a platelet filter unit to filter the predetermined amount of blood to generate a filtered blood; utilizing a plasma separation unit to divide the filtered blood into a plasma layer and a blood cell layer for separating blood cells from blood plasma; and extracting the blood plasma from the plasma layer and the blood cells from the blood cell layer. In another embodiment, the blood isolation and extraction method further includes: providing a platelet-washing unit to wash the platelet filter unit with a solution to produce a platelet solution; and mixing the platelet solution with the blood plasma to produce a platelet and plasma mixed solution.

A functional polymer membrane having a pore volume fraction of 0.6% or more and 3.0% or less by allowing a reaction of curing a composition containing a polymerizable compound (A) and a copolymerizable monomer (B).

The invention relates to a technique for handling liquid radioactive waste from a nuclear fuel-energy cycle, and may be used in a process for processing liquid radioactive waste for maximally reducing the volume thereof and removing radionuclides by concentrating same in a solid phase. The aim is achieved by means of a method for processing liquid radioactive waste and for the recovery thereof, including waste oxidation, separating sludge, colloids and suspended particles from a liquid phase, and removing, from the liquid phase, radionuclides to be subsequently recovered using selective sorbents and filters; the method is characterized in that, prior to the stage for separating sludge, colloids and suspended particles from the liquid phase of the radioactive waste, selective sorbents in the form of powders are added and mixed into the liquid waste.

A separation material includes a matrix that is bound to a saccharide, enabling the separation from a liquid of substances that selectively bind the saccharide. A method for preparing the separation material and a method for separating substances from a liquid that selectively bind a saccharide of the separation material are also described. A device employs the separation material for separating from a liquid substances that selectively bind to the saccharide of the separation material.

Provided herein are filtration membranes, method of manufacturing said membranes and use of such membranes for the removal of substances from fluids or substances.

A filter for a liquid purifier may include a filter housing having an inlet and an outlet; and a filter module provided in the filter housing, and configured to purify liquid introduced through the inlet, and to supply the purified liquid to the outlet. The filter module may include an electrostatic adsorption nonwoven fabric having a hollow portion. The filter module may be configured to receive the liquid introduced through the inlet is to pass through the electrostatic adsorption nonwoven fabric and then is to discharge out of the outlet of the filter housing.
