In this study, Bio-based carbon nanotubes (CNTs) have received considerable research attention due to their comparative advantages of high level stability, simplistic use, low toxicity and overall environmental friendliness. New potentials for improvement in heat transfer applications are presented due to their high aspect ratio, high thermal conductivity and special surface area. Phonons have ...

  A refrigeration cycle is a chain of various pieces of equipment including compressors, condensers, evaporators, and expansion devices each of which takes on a particular thermodynamic process duty in the cycle that eventually results in the production of the required refrigeration. The results of optimized mixed refrigerant cycles (MRCs) in Part I show that the configuration of MRC is an eff...

In low-temperature processes, heat rejected from separation columns is removed by refrigeration systems to heat sinks (reboilers & pre-heaters), process streams, other <span style="font-size: 10pt; col...

BACKGROUND Heating temperature is an important factor affecting meat palatability. This study aimed to evaluate the influence of heating temperature on some eating quality indicators, protein degradation and ultrastructure of pork muscle fibres and their correlations. RESULTS Cooking loss (CL) increased gradually (P < 0.05) with increasing temperature. Warner-Bratzler shear force (WBSF) incre...

Epitaxial graphene films examined were formed on the Si-face of semi-insulating 4H-SiC substrates by a high temperature sublimation process. A high-k gate stack on the epitaxial graphene was realized by inserting a fully oxidized nanometer thin aluminum film as a seeding layer, followed by an atomic-layer deposition process. The electrical properties of epitaxial graphene films are retained aft...

Background: Hydrocarbons degradation is principally achieved by microorganisms in natural environments. The extent of hydrocarbons biodegradation is mainly conditioned by environmental factors and its success depends on the optimal condition for the crude oil degrading isolates. Objectives: The aims of the current study was to isolate and identify crude oil degrading bacterium from surface sed...

The modern communication technologies require the use of CMOS monolithic oscillators because of their small manufacturing costs and high integration capabilities. The disadvantages of CMOS ring oscillators can be compensated through the use of a VCO architecture. The control voltage of this VCO should compensate for the frequency drift due to process and temperature.

In this work, we demonstrate a single-layer encapsulation method for poly(3,4ethylenedioxythiophene) (PEDOT). This method is achieved by initiated chemical vapor deposition (iCVD) process, which is scalable and employs solvent-free and low-substrate temperature conditions. The encapsulant used, poly(divinylbenzene-co-maleic anhydride) (PDVB-MA), was first time synthesized via vapor phase proces...

The aim of this work is to study the heterogeneous oxidative degradation of ofloxacin antibiotic using a composite material prepared from sodium alginate and cyclohexane dinitrilo tetraacetic acid (CDTA). The characterization tests indicated the successful incorporation of metal chelator and iron. It was also demonstrated that the synthesized beads are mesoporous. The influence of several exper...

An on-chip process, supply voltage, and temperature (PVT) compensation technique for low-voltage CMOS digital circuits was proposed. Because the degradation of circuit performance originates from the variation of the saturation current in transistors, we developed a compensation circuit consisting of a reference current that is independent of PVT variations. The circuit is operated so that the ...
