OBJECTIVES To investigate the influence of different temperatures on the compressive strength of glass ionomer cement (GIC) modified by the addition of silica-coated wax capsules; Material and Methods: Commercially-available GIC was modified by adding 10% silica-coated wax capsules. Test blocks were fabricated from pure cement (control) and modified cement (test), and stored in distilled water ...

We have studied the ground state of a fullerene-based magnet, the alpha;{'}-phase tetra-kis-(dimethylamino)-ethylene-C60 (alpha'-TDAE-C(60)), by electron spin resonance and magnetic torque measurements. Below T(N) = 7 K, nonparamagnetic field dependent resonances with a finite excitation gap (1.7 GHz) are observed along the a axis. Strong enhancement in their intensity as temperature is decreas...

Superconductivity observed in alkali-intercalated, solid C60 can be explained on the basis of conventional Bardeen-Cooper-Schrieffer theory. Intramolecular Jahn-Teller-type vibrations with high frequencies couple to conduction electrons in C60 7T" orbitals with strength V. The density of these states (N) is determined by the relatively weak intermolecular coupling. This results in a real space ...

The mechanisms of formation of a metastable defect isomer of fullerene C 60 due to the Stone-Wales transformation are theoretically studied. It is demonstrated that the paths of the " dynamic " Stone-Wales transformation at a high (sufficient for overcoming potential barriers) temperature can differ from the two " adiabatic " transformation paths discussed in the literature. This behavior is du...

In the industrial processes, lipases are expected to operate at temperatures above 45 °C and could retain activity in organic solvents. Hence, a C-terminal truncated lipase from Staphylococcus epidermis AT2 (rT-M386) was engineered by directed evolution. A mutant with glycine-to-cysteine substitution (G210C) demonstrated a remarkable improvement of thermostability, whereby the mutation enhanced...

Over the last few decades, many researchers have investigated in detail characteristics of bioactive compounds such as polyphenols, vitamins, flavonoids, and glycosides, volatile fruits, vegetables medicinal aromatic plants that possess beneficial properties, well consumer acceptance preference. The main aim this article is to provide an updated overview recent research endeavors related effect...

Cassava starch, typically, has resistant starch type 3 (RS3) content of 2.4%. This paper shows that the RS3 yields can be substantially enhanced by debranching cassava starch using pullulanase followed by high pressure or cyclic high-pressure annealing. RS3 yield of 41.3% was obtained when annealing was carried out at 400MPa/60°C for 15 min, whereas it took nearly 8h to obtain the same yield un...
