Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

Lignin Chemistry

Lignin History Lignin is a plant-derived biopolymer with several applications. It is considered an effective alternative to chemically synthesized plastics that pose serious environmental problems during manufacture and disposal. Lignin is often obtained as a byproduct in paper and pulp manufacture. Lignin has to be dissolved to obtain cellulose from wood. In 1838, Anselme Payen discovered that wood contained cellulose, and oxidizable coatings (later called lignin) that bind the cellulose together (McCarthy and Islam, 2000). This coating material could be removed from wood after acid treatment and washing with an aqueous alkali solution (McCarthy and Islam, 2000). Later, several ...

Introduction

Strategic management plays a vital role in the development of every organization as it provides the opportunity to the business to expand in the future.

The process is important as it is linked with the mission and vision statement of the organization/company. There is a need to supervise and amend/edit the strategies of a corporation with the analysis and demand of external ...

Introduction

Costco Wholesale Corporation formed their corporate sustainability and energy group in 2007 to spearhead the creation and implementation of the sustainably sourced strategies for products and energy policy. Their energy policy included a program for reduction of greenhouse gas emissions with the implementation of measures for energy efficiency. In 2007, Costco discovered that 85 percent of their carbon footprint was coming from purchased electricity. Their energy program placed emphasis on energy efficient operations and building designs. Costco also started working to reduce their deliveries by consolidation of freight at their distribution centers and increasing the load of every truck ...

ABSTRACT

The research argues that although a gas flaring stoppage is not successfully in-place in Nigeria, fitting the appropriate technology with complementary economic and institutional factors can lead to near-zero or zero gas flaring. Nigeria is a developing country with a unique culture of many tribes and one of the largest growing urban populations in the world. Infrastructural, political and economical challenges to meeting the goal are introduced. Reinjection of gas back into wells is not available as an option to gas flaring because a large region for gas production is wetlands (Buzcu-Guven et al. 2012). Wetlands ...

Dax Cowart’s Case

Dax Cowart should have been allowed to stop treatment. He was 25 years old during the accident and had full knowledge of his own capacity to tolerate the pain of treatments. He was also well aware of the quality of life that he would want for himself. The following sections describe his accident and treatments, relate the stand of Dax Cowart about his treatments, and discuss the rationale for euthanasia in the case of Dax Cowart.

The accident and treatments

The accident that changed Dax Cowart took place in 1973, in Henderson Texas. On their way home, Dax and his father stopped to ...

Introduction.

Offshore oil drilling and affiliated technological advances have long been considered to be the driving force of the oil industry, the backbone of our economy. In a fast technologically evolving age, the oil industry has not been left out. That is continuing to affect demand and supply of energy as seen in the past. The industry has been seen to involve complex processing of big data gathered at the various stages of oil production: exploration, discovering and it is processing. Petroleum science is steadily evolving from traditional under-developed geology to highly advanced super computer 3D calculations and analysis of the ...
