    ceramic membrane
  • Ceramic membranes are a type of artificial membranes made from inorganic metarials (such as alumina, titania, zirconia oxides or some glassy materials). They are used in membrane operations.
    filters
  • A screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components
  • (filter) device that removes something from whatever passes through it
  • A porous device for removing impurities or solid particles from a liquid or gas passed through it
  • A device for suppressing electrical or sound waves of frequencies not required
  • (filter) remove by passing through a filter; "filter out the impurities"
  • (filter) an electrical device that alters the frequency spectrum of signals passing through it

Ceramic Membranes for Separation and Reaction
Ceramic Membranes for Separation and Reaction
Ceramic Membranes for Reaction and Separation is the first single-authored guide to the developing area of ceramic membranes.
Starting by documenting established procedures of ceramic membrane preparation and characterization, this title then focuses on gas separation. The final chapter covers ceramic membrane reactors;- as distributors and separators, and general engineering considerations.
Chapters include key examples to illustrate membrane synthesis, characterisation and applications in industry.
Theoretical principles, advantages and disadvantages of using ceramic membranes under the various conditions are discussed where applicable.

Multicomplex Management (MCM) Expected Creative Potential (ECP) Picture 1 - Organization Structure Organization Structure Model used: Nordic Industrial Fund - Nordic Council of Ministers – Bio & Chemistry Division (BCD) - Division REI-activities (Research / Education / Innovation): 5 programmes: NordFood, Nordic Wood, NordPap, NordBio and NordYeast; 748 projects; 6.000 participating private and public companies, institutions, organizations and agencies in 62 countries. BCD connected 180.000 researchers, operators, engineers, technicians and company, organization and agency executives (1998). BCD was - in combination with NordTek (the organization managing the cooperation of the 23 Nordic technical universities) - the largest industrial and technological REI-network in Northern Europe. BCD was a 27.000 ECP Organization connecting 275.000 people totalling 2.8 million ECP.

In 1987 the organization expanded by taking over the activities of NordForsk (a Nordic government agency for basic research). In the new century the activities of NIF (and BCD) were split up between two new-established organizations: A new NordForsk (basic research) and Nordic Innovation Centre (NICe)(applied research and innovation).

Artificial Diamonds and Fuel Cells
Artificial Diamonds and Fuel Cells
Scientists at EMSL have built a membrane from a specialized cubic zirconia or artificial diamond that might allow petroleum-free fuel cells to operate at lower temperatures. Reducing a fuel cell's operating temperature would permit the use of stainless steel, instead of expensive ceramics. The key to reducing the temperature, and thus the cost, is the membrane that conducts oxygen quickly, with little to no resistance, from one side of the cell to the other. Using oxygen-plasma-assisted molecular beam epitaxy, the researchers grew scandia-stabilized zirconia films on sapphire substrates. The films were examined using x-ray diffraction, electron spectroscopy, and microscopy. The experimental research showed the cubic phase existed over a wider dopant concentration range than previously observed: 4.6-17.6 mol.% Sc2O3. The scientists found that the scandium doping in the cubic zirconia film conducted oxygen faster than the yttrium doping in current electrolytes. Applying modeling and other theoretical approaches to the experimental data, the team determined the nanoscale, nanosecond interactions that were occurring that led to the faster ion migration. Using nanoscale studies, scientists are gaining an atomic-level understanding necessary to design affordable, efficient electrolytes.

Recent Advances in Gas Separation by Microporous Ceramic Membranes, Volume 6 (Membrane Science and Technology)
This book is dedicated to the rapidly growing field of microporous ceramic membranes with separating layers of pore diameter less than 2nm.
The chapters of this book bring forward a wide range of issues, namely fundamentals of complex sorption and transport processes in micropore structures, highly innovative methods of preparation of microporous membranes and examples of their possible commercial applications. This book presents insights by distinguished investigators, who have contributed significantly to the advance of research efforts in the diverse topics described herein.
Recently, significant progress has been made with respect to the development of novel microporous asymmetric membranes, mainly involving modification by means of deposition of additional material within the pores of the substrates. Most state-of-the-art technologies aiming in the development of microporous ceramic membrane are presented in the third section of the book. These include several material deposition methods and techniques on macroporous or mesoporous supports and substrates from the liquid or vapour phase, namely those involving sol-gel, zeolite and chemical vapour deposition techniques. In addition to the above-mentioned methods, the classical technique of carbonizing polymeric deposits along with one of the novel techniques of plasma-treating, organically deposited Langmuir-Blodgett films, are also presented. Nanophase mixed ionic-electron membranes for enhanced oxygen transport are described, which pose a strong candidacy for a number of significant commercial applications.
