Hydrazine is a chemical of utmost importance in our society, either for organic synthesis or energy use. The direct conversion NH3 to hydrazine highly appealing, but it remains very difficult task because the degradation thermodynamically more feasible than cleavage N?H bond NH3. As result, any catalyst capable activating will thus unavoidably decompose N2H4. Here we show that cavitation bubble...

Assessment of corneal biomechanics for pre- and post-refractive surgery is great clinical importance. Corneal affect vision quality human eye. Many factors such as, age, diseases refractive surgery. There a need non-invasive in-vivo measurement due to shape preserving as opposed ex-vivo measurements that destructs tissue. In this study, new approach assessing non-invasively using ultrasound est...

The equivalent circuit simulation plays an important role in the design of ultrasound transducer. However, existing methods are difficult to achieve effect matching and backing layer, not able accurately simulate transducer with cable. Especially application high frequency ultrasound, long cable has a great influence on performance To overcome these limitations, this paper proposed improved met...

Fullerene nanoemulsions were formulated in palm kernel oil esters stabilized by low amount of mixed nonionic surfactants. Pseudoternary phase diagrams were established in the colloidal system of PKOEs/Tween 80 : Span 80/water incorporated with fullerene as antioxidant. Preformulation was subjected to combination of high and low energy emulsification methods and the physicochemical characteristi...
