Organizations are like individuals; they are unique entities with their own identity and cultural set of values. In the pursuit of originality, innovation, and effectiveness, a healthy organization has to accommodate individuals that are simultaneously team players and individual thinkers. It is important to realize that the organization’s culture...

Almost 30 years ago, the United Nations issued "Our Common Future" in search of a sustainable development path; however, little has changed in our society since then. The question is: have we gone too far away from nature? Have we undermined that we are part of nature? The present chapter will discuss that sustainability is not a trade, but a philo...

Developing a responsible personal worldview is central to sustainable development, but achieving quality education to promote transformative learning for sustainability is thus far poorly understood. Most programs involving the education for sustainable development rely on changing behavior rather than attitudes. The emphasis is on the scientific a...

Brazil is globally known for many reasons, varying from its sizzling Copacabana beach to its immense Maracana stadium. It is revered as the birthplace of world-famous soccer players such as Pele, Garrincha, Tostao, Socrates, and Ronaldo, and envied for its eye-popping carnival suits and mesmerizing samba dancers, but there is much more to this coun...

Purpose The purpose of this paper is to enhance awareness and foment the concept of “eco‐citizenship” within today's students in higher education. Design/methodology/approach The paper takes the form of a literature review on environmental issues and spiritual thinking, student reports, discussion. Findings The paper's three main findings are: th...

Six Sigma, emotional intelligence, and workplace spirituality each represent areas of intense research as well as practical application. Each of these topics also seems to be gaining ground in our increasingly diversifying contemporary work environment. Why is that? Should these phenomena all be seen as distinctive elements, or is there an intercon...

A number of studies have been recently devoted to the preparation and characterization of binary skutterudite materials to investigate their potential as advanced thermoelectric materials. These studies show that the potential of these binary skutterudite compounds is limited because of their relatively large thermal conductivity. In order to achie...

A search was made for improved TE materials that could have higher efficiency than state-of-the-art SiGe alloys used in Radioisotope Thermoelectric Generators. A new family of materials having the skutterudite structure was identified (cubic space group Im3, formula (Fe, Co, Ni)As{sub 3}). Properties of n-type IrSb{sub 3}, CoSb{sub 3}, and their so...

The binary antimonide compounds of the skutterudite family have a good potential for thermoelectric applications as recent results at the Jet Propulsion Laboratory (JPL) have shown. However, the room temperature thermal conductivity of these materials is about 10 Wm−1K−1 with an estimated 80% contribution from the lattice. To achieve maximum ZT val...

The thermal diffusivity, heat capacity and thermal conductivity of solid samples of new, Li-stabilized, sodium beta double prime-alumina polycrystalline ceramic have been determined in the temperature range 500-1200 K. Unit cell parameters and the coefficient of thermal expansion have been determined using X-ray diffraction in the range 300-1273 K...

Ruthenium silicide is currently under development as a promising thermoelectric material suitable for space power applications. Key to realizing the potentially high figure of merit values of this material is the development of appropriate doping techniques. In this study, manganese and iridium have been identified as useful p- and n-type dopants,...

The iridium-silicon phase diagram on the silicon-rich side was investigated by means of X-ray powder diffraction, density, differential thermal analysis, metalography, microprobe analysis, and electrical resistivity. Attempts were made to prepare eight previously reported silicon-rich iridium silicide compounds by arc melting and Bridgman-like grow...

Investigation on ruthenium silicide is under development as a experimental efforts directed toward high thermoelectric figure of merit values by a factor of two or more. This material has been identified as a candidate to high figure of merit depend on an accurate and detailed theoretical consideration. By preliminary study on arc-melted samples, i...

Inelastic scattering of laser light found to indicate onset of gas-phase polymerization in plasma-enhanced chemical-vapor deposition (PECVD) of photoconductive amorphous hydrogenated silicon/germanium alloy (a-SiGe:H) film. In PECVD process, film deposited from radio-frequency glow-discharge plasma of silane (SiH4) and germane (GeH4) diluted with h...

Amorphous silicon (a-Si:H) and amorphous carbon (a-C:H) films have been deposited by electron cyclotron resonance (ECR) microwave plasma enhanced CVD. A high deposition rate of 25 A/sec and a light-to-dark conductivity ratio of 500,000 for a-Si:H films have been achieved by the ECR process using a pure silane plasma. ECR microwave plasmas have been...

In situ plasma diagnostics using coherent anti‐Stokes Raman spectroscopy have shown different dissociation characteristics for GeH 4 and SiH 4 in radio frequency (rf) plasma‐enhanced chemical vapor deposition of amorphous silicon germanium alloy (a‐SiGe:H) thin films. The GeH 4 dissociation rate in rf plasmas is a factor of about 3 larger than that...

Amorphous silicon germanium alloy (a-SiGe:H) thin films were deposited by r.f. glow discharge using SiH4, GeH4 and H2 gas mixtures. The SiH4 and GeH4 plasmas were analyzed by in situ coherent anti-Stokes Raman spectroscopy (CARS) to determine the dissociation characteristics of SiH4 and GeH4. In situ CARS measurements of SiH4 and GeH4 number densit...

Highly photosensitive a-SiGe:H films with a light-to-dark conductivity ratio of 8*10³ and an optical bandgap of 1.40 eV have been produced by RF glow discharge using hydrogen dilution of SiH₄ and GeH₄ mixed gas plasma. The critical role of hydrogen dilution in GeH₄ containing plasmas is to suppress the ga...

It is demonstrated that the steady-state and kinetic characteristics of ECR (electron cyclotron resonance) and RF glow discharge plasmas can be readily monitored by OES (optical emission spectroscopy) in real time during a-Si:H and a-SiC:H film depositions using an OMA detection system. The ECR and RF glow discharge plasmas used for a-Si:H and a-Si...

Ohmic contacts of Au and Ag based Zn containing alloys on p-type Ga0.47In0.53As have been studied using intermediate layers of Ti and Ni, respectively. Low specific contact resistance in the order of 10−5 Ωcm2 are achieved. In case of AuZn alloy, the Ti intermediate metal layer causes higher contact resistances together with a worse contact morphol...

The purpose of this study was to determine if the students' epistemological beliefs is a significant predictor for their final physics grades in introductory physics courses and to compare the epistemological beliefs of the students from two different institutions, Woodbury University, USA and SKR College for women, Andhra University, India.
