Interaction of microwave radiation with wet porous material

چکیده
Moisture in building structures influences physical properties of materials and can cause their degradation. Apart from several exceptions, building materials are hardly ever dry. They always contain some moisture occurring in the solid, liquid or gaseous state. Moisture is a very variable quality with different effects on thermal and technical properties [4]. To express an anticipated negative effect of moisture on building materials related to building structures it is necessary to achieve as accurate way of determining their moisture characteristics as possible. Informative mention in conclusion of the European Standard EN ISO 15026 presents the moisture distribution and functional relation between Dw and ws on the basis of measurement by NMR method (nuclear magnetic resonance).

متن کاملMicrowave synthesis of zinc sulfite and porous zinc oxide microrods.
ZnSO(3) microrods with uniform size and shape can be prepared under microwave irradiation at much higher speed than a conventional heating bath, usually in minutes. The annealing of ZnSO(3) microrods produced porous ZnO microrods with pore size between 50-200 nm.
متن کاملMicrowave synthesis of hybrid inorganic-organic porous materials: phase-selective and rapid crystallization.
Microwave synthesis of two porous nickel glutarates was compared with conventional hydrothermal synthesis. The cubic nickel glutarate, [Ni20(C5H6O4)20(H2O)8] x 40 H2O (1), was synthesized by conventional electrical heating in several hours or days, depending on synthesis temperature. Crystallization was greatly accelerated by microwave irradiation, in which more stable, tetragonal nickel glutar...
متن کاملPorous hydroxyapatite for artificial bone applications
Hydroxyapatite (HA) has been used clinically for many years. It has good biocompatibility in bone contact as its chemical composition is similar to that of bone material. Porous HA ceramics have found enormous use in biomedical applications including bone tissue regeneration, cell proliferation, and drug delivery. In bone tissue engineering it has been applied as filling material for bone defec...
متن کاملMicrowave Hydrothermal Synthesis of Terbium Ions Complexed with Porous Graphene for Effective Absorbent for Organic Dye
A luminescent terbium ions/reduced graphene oxide complex (Tb-RGO) was successfully and rapidly synthesized by the microwave hydrothermal reaction via the interactions between terbium ions and the active oxygen functional groups of graphene oxide. The as-prepared material was porous stacked by multilayer graphene in all directions. Thus, the resulting product owed the high specific surface area...
