Sealed containers for radioactive material are presented herein. A sealed container forms an interior envelope for housing a radioactive material and prevents escape of the radioactive material into a surrounding environment. The sealed container provides a diffusion window for gaseous decay products to escape at a particular diffusion rate. In one example, an apparatus, comprises a container forming a sealed interior envelope for a radioactive material. The container has an aperture covered by a window material, and properties of the window material are selected to provide for diffusion of at least one gas produced by radioactive decay of the radioactive material.

A whole blood hollow fiber membrane filter medium is provided with a ceramic material having pores of a pore size that ensures permeability to blood plasma or serum and its molecular components while blood cells are retained. The whole blood hollow fiber membrane filter medium is used for separating blood plasma from whole blood, wherein the blood plasma preferably shows no hemolysis.

The present invention concerns gas-separation membranes. In some embodiments, the membranes comprise nano- or microislands or non-continuous metal layers suitable to adsorb, react with and/or otherwise retain at least one of the gases to be separated from a mixture of gases. In one embodiment, the membrane comprises a porous graphene membrane on which Pt or Pd nanoislands are deposited using a mesh, while the nanoislands are suitable to retain and bind to H.sub.2 while letting helium pass in a H.sub.2/He gas mixture. In another embodiment CO.sub.2 is separated from a H.sub.2/CO.sub.2 mixture. The membranes exhibit both, high selectivity and permeance and can be operated at room temperature.

A filtration membrane (1) is provided that includes a porous support (4) and a membrane layer having a first and a second zone (2, 3). The first zone (2) has a thickness of 5 to 15 m and an average pore opening size of smaller/equal 0.4 and the second zone (3) has a thickness of 5 to 40 m and an average pore opening size of 0.5 to 5.0 m. The filtration membrane (1) is produced by forming a single- or -double-layer coating on the porous support (4).

The present invention relates to a tangential flow separator element for separating a fluid medium for treatment into a filtrate and a retentate, said separator element having a monolithic rigid porous support (2) of rectilinear structure and having a single channel (3) arranged therein for passing the flow of the fluid medium for treatment, the outside surface (5) of the support presenting a profile that is constant. According to the invention, the monolithic rigid porous support (2) defines obstacles (9) to the flow of the fluid for filtering, which obstacles extend from the inside wall (3.sub.1) of said channel (3), are identical in material and porous texture to the support, and present continuity of material and of porous texture with the support, said obstacles (9) generating variations in the flow section of the channel.

The present invention relates to a combined C3/C4 splitter with a membrane system. More specifically, the present invention relates to a combined C3/C4 splitter column to separate highly pure propylene product from a liquefied petroleum gas stream, which eliminates a C3 splitter having over 120 trays and the additional equipment that a C3 splitter requires.

A lithium-air battery includes a battery cell and a case configured to accommodate the battery cell. The case includes an inlet communicating with outside and an outlet communicating with outside. At least one of the inlet and the outlet is equipped with a gas separation membrane that includes a matrix including a polymer resin and a metal-organic framework (MOF) dispersed in the matrix. The gas separation membrane has a thickness of 150 ?m or more.

A zeolite membrane composite includes a porous support and a zeolite membrane formed on at least one surface of the porous support. The zeolite membrane of the zeolite membrane composite is formed of an X-MOR-type zeolite, where X includes at least one type of transition metal ion.

A method of assessing a membrane, including calculating fluid dynamic characteristics of at least one of a membrane and a material to be passed through the membrane, where the material comprises particles; obtaining characteristic of at least one force acting on the particles of the material to be passed through the membrane due to the interaction between the particles and the membrane, the at least one force being an intermolecular force; combining the calculated fluid dynamic characteristic and the obtained characteristics to assess the flow of the material through the membrane; and optimizing at least one characteristics of the membrane in relation to the material. The membrane includes a plurality of rows and a plurality of teardrop structures arranged in the plurality of rows. The teardrop structures in each row are arranged at substantially the same angle with respect to an anticipated direction of flow through the membrane.
