• TiO 2 nanoparticles modified by terephthalic acid in a supercritical CO . Effects of modifier ratio, temperature, and pressure were optimized RSM method. Modification is made molecules bonding chemically. rate obtained method was much higher. Modifier on the surface NPs affect their electrical property. This paper presents strategy for modification with carboxylic acids. The reaction between ...

We report on the induced ordering of dispersed chiral diphenylalanine (Phe-Phe) chains grown on the anisotropic Cu(110) and isotropic Cu(100) surfaces. Scanning tunneling microscopy (STM) data reveal that 2D extended hybrid molecular motifs can be fabricated by utilizing terephthalic acid (TPA) molecules as linkers. These act as a molecular "glue" to bridge the isolated Phe-Phe chains without a...

This article provides a rigorous proof of a conjecture by E. C. Bain in 1924 on the optimality of the so-called Bain strain based on a criterion of least atomic movement. A general framework that explores several such optimality criteria is introduced and employed to show the existence of optimal transformations between any two Bravais lattices. A precise algorithm and a graphical user interfac...

The aim of this investigation was to determine if cavitation occurred around dental ultrasonic scalers and to estimate the amount of cavitation occurring. Three styles of tip (3 x TFI-10, 3 x TFI-3, 3 x TFI-1) were used, in conjunction with a Cavitron SPS ultrasonic generator (Dentsply, USA), to insonate terephthalic acid solution. The hydroxyl radical, [*OH], concentration, produced due to cav...
