In Vitro Effect of Ultrasound on Bacteria and Suggested

Influence of sonication temperature and time on the outcome of sonication. Bacteria were grown overnight on agar plates under the different conditions described in Table 1 . Overnight colonies were suspended in sonication buffer (0.1 M phosphate-buffered saline [PBS] or 0.9% [wt/vol] sodium chloride [saline]) and diluted to a final concentration of 1 10 3 CFU/ml.

XRD

Introduction Graphene and graphite oxide have gained vast popularity and become wonder materials in the present context of research and development. 1-3 The discovery of single-layer graphene which received unprecedented interest because of its two dimensionality and unique physical, chemical and electrical properties such as high intrinsic carrier mobility, quantum electronic transport

Thermal Analysis of Ductile Iron Casting

2017/4/10The time span between inoculation treatment and pouring has a significant effect on elongation but less effect on the tensile strength and hardness of castings []. The ratio of ferrite to pearlite in the matrix and the morphology of graphite influence the mechanical properties of ductile iron castings.

ultraDAWN light scattering detector for Real

RT-MALS greatly accelerates scale-up: it provides real-time feedback, indicating the effect of method tweaks on CQAs, while simultaneously reducing effort and the number of samples analyzed off-line. Unlike complex at-line PAT devices, ultraDAWN can simply be left in the process flow upon completion of scale up, for continuous or periodic monitoring of the final process.

Temperature dependence of the electrical transport

2013/7/25We report a systematic investigation of the temperature dependence of electrical resistance behaviours in tri- and four-layer graphene interconnects. Nonlinear current–voltage characteristics were observed at different temperatures, which are attributed to the heating effect. With the resistance curve derivative analysis method, our experimental results suggest that Coulomb interactions play

Enhanced mechanical and thermal properties of electrically

2019/9/23Fig 1 shows the effect of ultrasonication time and GNP weight fractions on the tensile properties of composites. From the investigation on ultrasonic treatment and time, it was clearly observed that the ultrasonication provided at an appropriate time has a positive influence on tensile strength and Youngs modulus, as illustrated in Fig 1(A) .

Effect of pasteurization temperature on stability of an

Effect of pasteurization temperature on stability of an acidified sugarcane juice beverage POD presented residual activities between 0.1 and 17.9 U/mL. These results demonstrate that the three time/temperature binomials effectively inactivated PPO, but to

Effect of expandable graphite and ammonium

This research aims to study the effect of ammonium polyphosphate and expandable graphite on the intumescent coating formulations (ICF). The coating presented in this research article is based on carbon source expandable graphite (EG), blowing agent melamine, acid source ammonium polyphosphate (APP), epoxy resin as a binder with polyamide amine.

Effect of Ultrasonication Duration on Colloidal Structure

The effect of dispersing energy (ultrasonication) on viscosity, thermal cond., and the laminar convective heat transfer was studied. Results indicate that thermal cond. and heat transfer enhancement increased until an optimum ultrasonication time was reached

Effect of Ultrasound on Some Chemical and

The effect of amplitude level on antioxidant capacity of sour cherry juice was also found significant (p 0.05). Color parameters (L*, a*, b*, C, h) generally increased by increasing temperature, amplitude level, and treatment time. It was determined that

Analysis of the Temperature Distribution on the Surface

The temperature distribution on the surface of the briquettes can testify the locally exerted pressure on the briquette. The stress distribution in the briquetting material is still a subject of research. The article includes thermography studies of the briquetting

Effect of Sonication on the Synthesis of Exfoliated Graphite

Microcrystalline graphite is subjected to intercalation using strong concentrated acid (H 2 SO 4) along with a peroxide (H 2 O 2) followed by thermal exfoliation and then ultrasonicating the product in acetone for five different time periods to show the effect of
