The first purpose of this study was to investigate the effect operating variables and surfactant concentration in subcritical water after ultrasonic process on sugar-producing yield from coconut husk. second obtain optimum condition process. sonication before done by dispersing 40 mesh husk powder at 60°C, 35 kHz. time studied comparing material crystallinity composition being treated for 30 mi...

The use of nanomaterial as a finishing agent in the textile industry continues to be developed. Nanoparticle zinc oxide (ZnONP) has anti-UV properties so that it can used protect color fabric from fading. Constraints using functionalization on are process application and also its poor adhesion. This research aims optimize ZnONP coating cotton-indigo maximized adsorbed with good durability. Opti...

Gold nanoparticles were synthesized by chemical reduction of HAuCl4 inside the pores of a polycarbonate-based membrane followed by dissolving the membrane in dichloromethane and further sonication. Sonication time as the main affecting factor on the nanoparticle size was investigated. The characterization by transmission electron microscopy showed the formation of gold nanoparticles with diamet...

The blood-retinal barrier (BRB) prevents most systemically-administered drugs from reaching the retina. This study investigated whether burst ultrasound applied with a circulating microbubble agent can disrupt the BRB, providing a noninvasive method for the targeted delivery of systemically administered drugs to the retina. To demonstrate the efficacy and reversibility of such a procedure, five...

Triangular gold nanoplates in CTAB solution were selectively precipitated on a glass wall in ambient conditions and the nanoplates could be easily recovered by a brief sonication.

Nanocrystals with tunable morphologies and optical properties were successfully fabricated from an organic functional low-molecular-weight compound, 2,4,5-triphenylimidazole (lophine), through a sonication technique.

Exfoliated 2D materials including graphene, BN, MoS(2) and WS(2) are accessible in water over a wide range of pH for a synergistic process involving sonication in the presence of p-phosphonic acid calix[8]arene.

Various procedures of mixing starting powders for hot-pressing α-SiAlON ceramics were studied. They included different milling methods (attrition milling, ball milling, and sonication), liquid medium (water, isopropyl alcohol, and pyridine), and atmospheres (ambient air and nitrogen). These mixing procedures resulted in markedly different densification behavior and fired ceramics. As the powder...
