About 40 percent of all the energy consumed by buildings worldwide is used for space heating and cooling. With the warming climate as well as growing populations and rising standards of living — especially in hot, humid regions of the developing world — the level of cooling and dehumidification needed to ensure comfort and protect human health is predicted to rise precipitously, pushing up global energy demand.Much discussion is now focusing on replacing the greenhouse gases frequently used as refrigerants in today’s air conditioners. But another pressing concern is that most existing sys...

Scalable manufacturing process spools out strips of graphene for use in ultrathin membranes.MIT engineers have developed a continuous manufacturing process that produces long strips of high-quality graphene.The team’s results are the first demonstration of an industrial, scalable method for manufacturing high-quality graphene that is tailored for use in membranes that filter a variety of molecules, including salts, larger ions, proteins, or nanoparticles. Such membranes should be useful for desalination, biological separation, and other applications.“For several years, researchers have thought...

Recently, our company has launched a new V hole AAO template. Its overall structure is similar to the previous traditional AAO template, but its channel cross-section is not rectangular, but inverted cone, the channel aperture from the top to the bottom smooth transition. The center spacing of the pore is about 450 nm, the depth of the pore is about 900 nm, the top diameter of the pore is about 450 nm, and the bottom diameter is about 100 nm.The pore of this kind of structure is widely used in the preparation of nanomaterials. For example, the V-shaped pore can be easily used to cast PDMS and ...

An Australian research team headed by two young Chinese and Korean doctors has developed a method to produce graphene, a nanomaterial 200 times harder than steel, from soybean oil eaten in daily life, which greatly reduces commercial production of graphene, according to the Sing Tao Daily. The cost of future materials.One of the co-authors of the study, Zhao Junhan, a Chinese-American from the Australian Academy of Sciences (CSIRO), said that this way of making graphene could produce the nanomaterials faster and cheaper than other methods developed by scientists around the world.The research r...

According to Sohu Public Platform January 13, 2017, recently, the Bass Advanced Separation Engineering Center (CASE) scientists are predicting the development of 3D printing and advanced membrane engineering. It is understood that membranes are semipermeable selective barriers that separate gas or liquid molecules into two streams. A common example is reverse osmosis membranes, which separate salt from water.In a new article published in the Journal of Membrane Science, CASE researchers noted several limitations that currently exist in membrane engineering. Due to the limitation of current man...
