Abstract:

<p><em>The study was conducted to compare the performance of students working in chemistry laboratory with those working in chemistry laboratory supplemented with simulations at secondary school level. The focus of the study was to find out the effectiveness of laboratory work supplemented with simulation on the performance of students. The study was experimental in nature and posttest only control group design was used. Qualitative data is collected by means of interview of chemistry teachers. Quantitative data was also collected and analyzed. The sample comprised of 118 (60 males

Abstract:

Chemistry is one of the most important branches of science and its knowledge is necessary in the understanding of composition, properties and behavior changes of matter that form the environment around us. Chemistry is highly important in modern societies because of its requirement as a prerequisite to the study of many other science oriented courses such as medicine, engineering and pharmacy. Due to the significance of chemistry, there is need for students to be academically prepared at secondary school level for higher level pursuits. Chemistry as a subject in Kenya is introduced to learners

Abstract:

The focus of the paper is on Rein Vihalemm’s novel approach to science called practical realism. From the perspective of Vihalemm, science is not only theoretical but first and foremost a practical activity. This kind of approach puts chemistry rather than physics into the position of a typical science as chemistry has a dual character resting on both constructive-hypothetico-deductive (ϕ-science) and classifying-historico-descriptive (non-ϕ-science) types of cognition. Chemists deal with finding out the laws of nature like the physicists. However, in addition to this they deal with substances

Abstract:

Raymond Lemieux was one of the outstanding chemists of the second half of the twentieth century. During the four decades from 1950 onwards he dominated the field of carbohydrate chemistry. His rare and special degree of insight into chemical problems resulted in numerous seminal discoveries and observations that influenced organic chemistry extensively, and provided the area of carbohydrate chemistry—and its associated subjects—with extremely significant conceptual and experimental tools. His work was a determining factor in converting this field from an academic specialization into one of gre

Abstract:

Chemistry and chemical engineering have changed very significantly in the last half century. From classical sciences they have broadened their scope into biology, medicine, physics, material science, nanotechnology, computation and advanced methods of process engineering and control. The applications of chemical compounds, materials and knowledge have also dramatically increased. The development of chemical sciences in the scientifically most advanced countries, at the end of the last century was extrapolated to the next several decades in this review and challenges for chemists and chemical e

Abstract:

The main purpose of this study is to explore the epistemological problems underlying pre-service chemistry teachers’ aims in using practical work, i.e., individual or small group object manipulation or observation, in school science. Twenty-two pre-service chemistry teachers participated in this study. Qualitative data collection tools included participants’ reflections about some practical work cases; participants’ practical work plans; responses given to open-ended questions about practical work, scientific inquiry, the epistemology of science, and science teaching approaches such as discove

Abstract:

We review the modern state of cellular automata (CA) applications for solving practical problems in chemistry and chemical technology. We consider the problems of material structure modeling and prediction of materials’ morphology-dependent properties. We review the use of the CA approach for modeling diffusion, crystallization, dissolution, erosion, corrosion, adsorption, and hydration processes. We also consider examples of hybrid CA-based models, which are combinations of various CA with other computational approaches and modeling methods. Finally, we discuss the use of high-performance par

Abstract:

Although mapping of human genes began early in the 20th century, about 99% of the genome is still unknown. Therefore, the development of new separation processes as well as a better understanding of the old separation techniques are needed to achieve the goals of this project. In 1994, P. Mayer, G. W. Slater and G. Drouin studied mathematically a new approach for the separation of DNA in free solutions where one attaches a neutral globular object at the end of the DNA molecule. This object would increase the friction and slow down the smaller DNA molecules more than the larger ones. In Chapter

Abstract:

With today’s growing restrictions in sources and chemical treatment, cooling water that has low corrosive potential is difficult to find. Today’s sources are more aggressive (corrosive) creating a greater challenge to the survival of tubing materials. Pitting and crevice corrosion have become much more common. This paper identifies and summarizes those changes, concerns, and provides suggestions on how a utility can prevent long-term problems. It will cover the water factors to consider and monitor, proper lay-up practices, and material selections based on cooling water chemistry and practices

However, including reduced mechanisms into a CFD analysis typically leads to numerical difficulties.
