Modified porous membrane material and preparation method thereof, and liquid membrane separation method of carbon dioxide
A membrane modification method for improving liquid membrane separation of carbon dioxide (CO.sub.2) includes grafting an organic substance containing an amine group on a porous membrane material, and loading water into pore channels of the porous membrane material to prepare a supported liquid membrane for a gas mixture separation experiment of CO.sub.2. In the method, the amine group is introduced through chemical grafting to make the water being alkaline when used as membrane liquid. Compared with an alkaline solution as the membrane liquid, the method can avoid the loss of active alkaline substances and increase the permeation flux of CO.sub.2.
Methods of extracting volatiles from ceramic green bodies
Methods of producing a ceramic article include heating the ceramic green body containing a quantity of one or more organic materials to extract only a fraction of the organic materials from the ceramic green body by exposing the ceramic green body to a process atmosphere which is heated to a hold temperature of from 225° C. to about 400° C. and has from 2% to 7% O.sub.2 by volume of the process atmosphere. The method further includes cooling the ceramic green body to a temperature of below 200° C., exposing the ceramic green body to a higher concentration of O.sub.2 than in the process atmosphere of the heating step, and firing the ceramic green body to form the ceramic article. Volatile extraction units for implementing the methods are also described.
SYSTEM AND METHOD OF MAKING PRINTED ARTICLES

A method of making an object by ink jet printing using the disclosed system is also disclosed.
THREE-DIMENSIONAL SHAPED ARTICLE PRODUCTION METHOD
A three-dimensional shaped article production method for producing a three-dimensional shaped article by stacking layers to form a stacked body includes a first layer formation step of forming a first layer on a support by supplying a first composition containing first particles and a binder, a second layer formation step of forming a second layer composed of one layer or a plurality of layers on the first layer by supplying a second composition containing second particles and a binder, and a separation step of separating the second layer from the support through the first layer, wherein after the separation step, a sintering step of sintering the second layer is performed.
DURABLE HIGH FRICTION COATING (DHFC) FOR BRAKE APPLICATION
Technologies are described for a durable high friction coating (DHFC), which may be manufactured by mixing a binder, a filler, and one or more additives in liquid form, loading the liquid mixture onto a coil material (metal substrate) and curing for subsequent cutting and/or stamping. The metal substrate with cured DHFC layer(s) may be cut to shape to form brake shims. Water-based binders may be used for environmentally friendly chemicals. In some examples, the binder(s) in the DHFC may be in a range from at least 70 weight% to less than 95 weight% and the filler(s) in a range from at least 5 weight% to less than 30 weight% with an elastomeric polymer in a range from at least 1 weight% to less than 8 weight% and a rheology modifier in a range from at least 0.5 weight% to less than 2 weight%.
