This chapter summarizes the knowledge about the genomes of psychrophilic bacteria, a subclass of the cold-adapted bacteria, with emphasis on the specific selective features relevant to cold adaptation. A detailed analysis of the general features of genomes and proteomes from psychrophilic bacteria is presented. All in…
The biotechnology industry has exploited the unique properties of the periplasm to produce industrially relevant products. For efficient periplasmic protein accumulation to occur, events in the cytoplasm related to translation initiation and protein folding of the mature domain need to be coordinated. In this chapter…
Acidophily is a trait of organisms referring to the ability to survive and preferentially multiply at low pH (<3). Extremely acidic environments are found in natural geothermal areas as well as in man-made habitats such as mining wastes. Acidophiles that thrive in these habitats are found among the archaeal, bacterial…
Cost required for the procurement of a thermoelectric module of a manufacturing industry (branded) until today, still relatively expensive because it is imported components with a limited number, thus resulting in the emergence of an alternative thermoelectric module which circulate freely in the market with a much ch…
The multicolor intense visible emission from Er3+ and Tm3+ ions codoped in TeO2–PbO glass upon excitation at ∼1064 nm radiation from a nanosecond pulsed Nd:YAG laser has been investigated. The optical parameters of erbium ions codoped in Tm3+–TeO2–PbO glass by using the Judd–Ofelt theory have been determined from the…
In the present study, a novel approach of wet mechanochemical oxidation of carbon nanotubes (CNTs) has been established in order to improve the uniformity in nanodispersion of the CNTs. This approach was found to be more efficient for CNT oxidation as compared to the acid oxidation method as observed from the Fourier…
The adaptability of field emitters in oxidizing environment is an important issue for practical applications. Herein, the effect of ozone exposure on the field emission property of molybdenum (Mo) nanowalls was studied. Results indicate that Mo nanowall cold cathode shows strong resistance to high doses of atomic oxyg…
In this paper, we take advantage of a facile fabrication technique called self-assembled nanosphere lithography (SANSL) combining with proper two-step reactive ion etching (RIE) method and radio frequency (RF) sputtering deposition process for manufacturing honeycomb diamond-like carbon (DLC) thin film structures with…
A method to grow boron nitrogen nanoheterostructures has been developed. This method is based on an alteration to a process that has been shown to be suitable for the growth of pure boron nanostructures. The technique uses the solid precursors MCM-41, nickel boride and magnesium diboride or magnesium tetrahydroborate…
We used LCR transmission lines to model right-handed (conventional material) and left-handed (electromagnetic metamaterial) systems. Both systems are perturbed by an electric field and expressions for the electrical conductivity are obtained. An expression that relates both conductivities is obtained, a numerical anal…
We design a structure to realize Rabi splitting and Rabi oscillation in acoustics. We develop rigorous analytical models to analyze the splitting effect from the aspect of phase matching, and from the aspect of mode coupling using a coupled mode model. In this model, we discover that the splitting effect is caused by…
Understanding the phase behavior of confined water is central to fields as diverse as heterogeneous catalysis, corrosion, nanofluidics, and to emerging energy technologies. Altering the state points (temperature, pressure, etc.) or introduction of a foreign surface can result in the phase transformation of water. At r…
In this paper, an effort has been made to investigate the incorporation of carbon nanotubes in structural composites in order to improve damage characteristics, such as delamination. The nanocomposite material is introduced in the damage-prone regions of complex aerospace stiffener sections; the methodology proposed i…
We report the results of nuclear magnetic resonance imaging experiments on granular beds of mustard grains fluidized by vertical vibration at ultrasonic frequencies. The variation of both granular temperature and packing fraction with height was measured within the three-dimensional cell for a range of vibration frequ…
Hydrozirconation on vinyl-terminated substrates (silicon wafer and nanosilica sphere) is employed as an efficient way for immobilization of zirconocene catalyst through Zr-C bonds, which is applied in surface coordination ethylene polymerization producing surface-tethered polyethylene (PE). The formation of Zr-C σ bon…
For decades, arid and semi-arid regions in Africa have faced issues related to water availability for drinking, irrigation and livestock purposes. To tackle these issues, a laboratory scale greywater treatment system based on high rate algal pond (HRAP) technology was investigated in order to guide the operation of th…
Purpose – The objective of the present investigation is to prepare a Zn–Al matrix (73 wt. per cent Zn + 27 wt. per cent Al) reinforced with SiC and graphite (Gr) hybrid composites by a rapid current sintering technique. Well-known Zn-based alloys are good candidates for load bearing applications. However, some limitat…
This chapter presents the insights into adaptation provided by the study of the four genomes of extreme halophiles sequenced to date. The focus then shifts to molecular adaptation of halophilic proteins, defined as proteins isolated from extreme halophiles. Different aspects concerning solvation, stabilization of the…
Abstract Yttrium silicate doped with cerium (Y2SiO5:Ce) was obtained from Y-Ce-Si based precursors prepared by the simultaneous addition of reagents (SimAdd) technique. The synthesis of the precursors was done in well controlled conditions using ammonium oxalate, ammonium carbonate or urea as precipitating agents. Res…
Use of compression molding with a natural fiber-reinforced thermoplastic matrix has been growing rapidly within the last few years in various applications. Wood-reinforced high-density polyethylene offers economic efficiency, a high process reproducibility, short cycle times, a stable and high component quality, and a…
