High-Intensity focused ultrasound linear array and system for dermatology treatment.

Dermatological lesions are typically located just a few millimeters below the surface of the skin, which constrains the efficacy of optical-based therapeutic methods such as photothermal and photodynamic therapy due to limited therapeutic depth caused by optical scattering. As an alternative, high-intensity focused ultrasound (HIFU) has been explored for its potential to treat a variety of dermatological conditions because it offers greater flexibility in terms of treatment depth. Since dermatological lesions have a small thickness ranging from 1.

Synthesis of Heterogeneous Li(4)Ti(5)O(12) Nanostructured Anodes with Long-Term Cycle Stability.

The 0D-1D Lithium titanate (Li(4)Ti(5)O(12)) heterogeneous nanostructures were synthesized through the solvothermal reaction using lithium hydroxide monohydrate (Li(OH)·H(2)O) and protonated trititanate (H(2)Ti(3)O(7)) nanowires as the templates in an ethanol/water mixed solvent with subsequent heat treatment. A scanning electron microscope (SEM) and a high resolution transmission electron microscope (HRTEM) were used to reveal that the Li(4)Ti(5)O(12) powders had 0D-1D heterogeneous nanostructures with nanoparticles (0D) on the surface of wires (1D). The composition of the mixed solvents and the volume ratio of ethanol modulated the primary particle size of the Li(4)Ti(5)O(12) nanoparticles.

Facile hydrothermal synthesis of porous TiO2 nanowire electrodes with high-rate capability for Li ion batteries.

Anatase TiO(2) nanowires were successfully synthesized using a low-temperature hydrothermal treatment on as-prepared one-dimensional (1D) hydrogen titanate nanowires (H(2)Ti(3)O(7)) at 180 degrees C. The anatase TiO(2) nanowires were porous in nature with a high specific surface area. These nanowires were characterized using transmission electron microscopy (TEM), high-resolution TEM, x-ray powder diffraction, Raman spectroscopy, and Brunauer-Emmett-Teller (BET) measurements.

Synthesis and characterization of nano-particulate BaTiO3 for ceramic/polymer composite capacitor.

BaTiO3 nano-particles with a size range of 20-70 nm were synthesized at 70 degrees C through a simple wet-chemical reactions between barium hydroxide octahydrate (Ba(OH)2 x 8H2O) and meta titanic acid (H2TiO3) in ethanol/water mixed solvent systems. It was found that the volume ratio of ethanol to deionized water is a key controlling parameter to determine the phase formation and particle size of BaTiO3. Single-phase cubic perovskite BaTiO3 started to be formed in solution containing above 40 volume percent of ethanol.
