Ultrasound is a form of mechanical energy with its acoustic pressure wave at frequencies range from 20 to 20,000 Hz. To date, ultrasound waves are not only used in imaging medicine for diagnosis, but also are performed in physical therapy (PT) medicine for the purpose of preventing and curing disease due to its thermal and nonthermal effects, and the ultrasound frequencies used in

-Curing of paints by exposure to UV radiations is emerging as one of the best film forming technique as an alternative to traditional solvent borne oxidative and thermal curing coatings. The composition and chemistry of UV curable coatings and role of multifunctional and monofunctional monomers, oligomers, and photoinitiators have been discussed. The limitations imposed by thermodynamic equilib...

The effect of nanoclay in combination with other inter fillers in ethylene propylene diene monomer (EPDM) rubber vulcanizate were studied. Curing characteristics were carried out using rubber process analyzer (RPA). Mechanical, thermal and morphology characterization of EPDM nanoclay composites were studied.

Purpose: This study aimed to evaluate the effects of light-curing method on the marginal seal and resin composite adaptation to the cavity wall, and the formation of enamel cracks around resin composite restorations. Materials and Methods: Cylindrical cavities were prepared on the buccal or lingual cervical region of human molars. The teeth were restored with Clearfil Liner Bond 2 V and filled ...

The most common bone cement material used clinically today for orthopedic surgery is poly(methyl methacrylate) (PMMA). Conventional PMMA bone cement has several mechanical, thermal, and biological disadvantages. To overcome these problems, researchers have investigated combinations of PMMA bone cement and several bioactive particles (micrometers to nanometers in size), such as magnesium oxide, ...

The reaction products and microstructure of an 8 M NaOH-activated fly ash (AAFA) cured with microwave thermal oven curing were comparatively investigated. results show that the formation Al-rich N-A-S-H gel a flaky morphology crystalline chabazite-Na between particles favoured under curing, whilst Si-rich fibrilllar hydroxysodalite on surface dominant curing. these unique is attributed not only...
