In 1992, Puciova and Toma published the synthesis of a broad range of oximes by microwave irradiation. They observed that the application of microwave heating enhanced... 

At small concentrations of Pd there will be a conduction-band resonance at each transitional-metal atom, and the resistance depends on the phase shifts. For Ag-Pd the resonance only just extends over the Fermi energy, giving very small residual resistance and specific-heat enhancement for Cu-Ni they are much larger.

Heat is transferred more rapidly from higher temperatures. Because at higher temperatures, the removal of heat is often more important than the acquisition of heat, enhanced heat transfer is beneficial. Because higher temperatures imply higher heat contents, systems at higher temperatures are usually more energetic than at lower temperatures. 

When the CHPs work in the heat-enhancement mode (Ogura and Mu-jumdar, 2000), the released energy from the CHP2 can be above 200% of the stored heat in the CHPl depending on the chemical system selected. On the other hand, when the temperature of the released heat from the CHP2 is required to be much higher than that of the stored heat in the CHPl, the temperature upgrade mode is especially effective.

Inhalation is usually clearly the most important route for occupational exposure to solvents. Organic solvents also enter the body through the skin. For some solvents, especially for alkoxyalcohols (glycol ethers) and their acetates, this is even the main route of absorption. Even the skin uptake of vapor can be significant for these compounds. Dermal absorption of vapors is, however, usually negligible and contact with liquid is required. Increased workload and heat enhance both inhalation and dermal absorption. Skin contamination may also lead to oral uptake due to eating and smoking but this is of minor importance for volatile solvents. 

Like LMX4, onset of clinically important anesthesia is much more rapid than EMLA. The local anesthetics used are not as likely to induce methemoglobinemia. The use of heat enhances vasodilatation and may facilitate venous identification. 

Wet digestions assisted by microwave radiation have been observed as safer and efficient. The procedures minimize contamination and amount of reagents for sample preparations (Ozcan and Akman, 2005), (Tiindade et al., 2006). Microwave heating enhances the...
