Cellulosic biomass can be used as a feedstock for biofuel manufacturing. Pelleting of cellulosic biomass can increase its bulk density and thus improve its storability and reduce the feedstock transportation costs. Ultrasonic vibration-assisted (UV-A) pelleting can produce biomass pellets whose density is comparable to that processed by traditional pelleting methods (e.g. extruding, briquetting...

Nickel nanotubes have been synthesized by the popular and versatile method of template-assisted electrodeposition, and a surface-directed growth mechanism based on the adsorption of the nickel-borate complex has been proposed.

Directing at the hard machinability of high volume fraction 70% SiCp/Al composites, a longitudinal and torsional ultrasonic-assisted milling (LTUAM) method is proposed to improve edge quality machining efficiency. By observing metallographic structure material, three-dimensional (3D) finite element model random distribution spherical, elliptical polygonal SiC particles established analyzed by A...

In this paper, hydroxyapatite coating was successfully deposited on ZK60 magnesium alloy surface by ultrasound-assisted electrodeposition method, and the macroscopic structure, chemical composition corrosion properties of sample HA were analyzed. The results show that quality is improved ultrasonic power, uniform, smooth compact. XRD FTIR analysis main obtained assisted hydroxyapatite. treatmen...

Ultrasonic-assisted grinding processing can effectively reduce the surface roughness and enhance efficiency in of hard brittle materials. However, most common ultrasonic assisted is a type contact where tool directly contacts workpiece, which means that it necessary to accurately control pre-pressure on workpiece. The will inevitably increase complexity device, easy wear workpiece because impro...

Power ultrasonic-assisted reservoir modification is a promising technique for enhanced coalbed methane recovery. However, the in-site performance of ultrasound-assisted CBM production has not yet been revealed. In current study, in situ antireflection test was conducted with high-power ultrasound ~18 kW underground coal seam, and investigated by measuring borehole drainage gas data field zone, ...

In this study, the effects of three different independent variables (extraction temperature, extraction time, ultrasonic power) on total phenolic content, yield and antioxidant capacity (IC50) value olive leaf extracts Halhalı variety which is originated from South-eastern Anatolia Region were investigated. As a result evaluation made with Box-Behnken Design Model, optimum conditions determined...

Ultrasonic Irradiation (UI) is an emerging technology that used to assist the CO 2 absorption process. Even for slow kinetic solvents without using any chemical promoter, high-frequency UI might enhance mass transfer during For this purpose, it essential study performance of a ultrasonic-assisted system under varied operating conditions. The ultrasonic power considered as one main parameters . ...

Drying is one of the widely used methods of food preservation and it is a sensitive food processing operation due to undesirable changes in the quality of dried product. In this study the effect of osmotic dyhedration and ultrasound pretreatment prior to convective drying on quality properties of apple slices was investigated. Apple slices were pretreated by osmotic dehydration in two concentra...
