Application of Xylopia aethiopica Seed Extract as Aluminium Alloy Corrosion Inhibitor in 0.75 M KOH Alkaline Solution | Chapter 9 | Advances and Trends in Physical Science Research Vol. 2

Corrosion  phenomena,  control  and  prevention  are  unavoidable  scientific  issues  that  should  be addressed due to increase of technological development. Aluminium (Al) is one of the most abundant elements found in the earth’s crust. The applications site of Almakes it to yield corrosion attack despite its corrosion resistance. The aim of alloying is to enhance the desired properties possessed by the Al. Plant extracts are rich source of naturally synthesised chemical compounds that can be extracted by simple procedure. The present study investigated the corrosion inhibition of Al alloy in 0.75 M  KOH  solution  at  room  temperature  using Xylopia  aethiopicaseed  extract.  The gravimetric technique was employed in the study. It was revealed that the presence of the spice extract in the test solution retards the corrosion rate.  The calculated inhibition efficiency from the inhibitor surface coverage was observed to increase linearly with the inhibitor concentration. The consideration of the Langmuir adsorption isotherm indicated that the mechanism of adsorption is Physisorption. Temkin isotherm models explained that there were lateral attractions of the inhibitor molecules on the Al alloy surface. Flory-Huggins isotherm model confirms that there is bulky displacement of water molecules on  the  metal  surface  due  to  the  presence  of  the  inhibitor  molecules.  This depicts that the  spice constituents clustered on the Al alloy surface preventing contact with the corrosive environment.

Empowerment and Leader Member Exchange towards Organizational Citizenship Behavior Readiness among Government Workforce in Malaysia | Book Publisher International

  State agencies are among the most significant entities that represent the public's needs, and their programmes are essential to a state's and the nation's economic growth and development. State agencies have been rife by public concerns for years, as demonstrated by the Public Complaints Bureau, as problems of inefficiency in service quality and delivery have yet to meet the public's standards. With the support of 15 employees from state agencies on Malaysia's east coast, this study aims to achieve three targets. The first and second objectives are to investigate the ties between leader-member exchange (LMX) and OCB empowerment. The final aim is to define the most significant factors that affect OCB willingness. A total of 288 people took part in the survey, which was conducted using a cluster sampling process. The survey items had achieved the necessary reliability, according to the pilot test results, and some sub-dimensions were renamed after factor analysis.

Re-asserting Cultural Perspectives: Old People and New Ideas in Bole Butake’s Lake God and The Survivors and Sankie Maimo’s Succession in Sarkov | Chapter 10 | Perspectives of Arts and Social Studies Vol. 2

African cultures have undergone transformations from the colonial period to the present, often to the detriment of its cultural evolution and within the larger global community. As it were, colonial education subordinated African communalism and created in its place an anti-African spirit evident in the assimilation of western values. This did not only end up in a kind of cultural betrayal, but also posed as a serious threat to the dignity and identity of the people. Those who fall prey to this kind of cultural imperialism are the young people who are often irrationally carried away by western fashion and modes that they tend to neglect and/or forget their cultural ways of life as they join the race of “progress.” This situation has given rise to a conscious effort by creative writers to re-assert and protect African values while at the same time liberating themselves from the longstanding western effort at suppressing, controlling and dominating their thoughts particularly through n

The Utilization of Agro-Waste: A Nanobiotechnology Point of View | Chapter 10 | Recent Advances in Biological Research Vol. 5

Aims: To review the utilization of agro-waste in the eco-friendly synthesis of nanoparticles and their biomedical, catalytic and industrial applications. Study Design: A review. Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary. Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ t
