2.4. Sucrose crystal structure Crystal habit is the term used to describe the appearance and shape of a crystal (Morel du Boil 1985). The conditions during growth of the crystal influence the development and morphology of the crystal. The morphology of a crystal grown in the presence of impurities is influenced greatly at the faces of the crystal most affected by the adsorption of impurities (Morel du Boil 1985). Therefore, the presence of impurities was thought to possess the greatest…

The History of medicine started in 2600 BC in Egypt. They describe the diagnosis and treatment of two hundred disease . Egyptian believed that disease came from god, demons, and spirits. Egyptian doctors believed that there was channel in the body; they were trying to find a way to unblock the channels. Egyptian were the first in the world that were able to document everything this helped scientists to make calculation years later .Egyptian also created bathrooms so disease won’t spread .…

Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

This is why the diffraction fringes of radio waves will be large and images produced will be blurry and of poor quality. To solve this problem radio astronomers have turned to interferometry. It is an advantageous technique since it can provide measurements of stars with a…

Gregor Mendel, known as the “father of modern genetics”, he was born in Austria in 1822. Mendel was sent to a secondary school in Troppau to continue his education, he grew up in a German speaking family and graduated high school in 1840. After his graduation he went onto a 2-year program at the Philosophical Institute at Olmutz University. Around 1854, Mendel began to research the transmission of hereditary traits in plant hybrids. At the time of Mendel’s studies, it was a generally accepted…

Deoxyribonucleic acid is known as the molecule of inheritance where its structure dictates its function in storing the genetic information of the organism (Rafael, 2010). This molecule contains genes which encode proteins needed for the complex biochemical metabolic reactions which occur within the organism (Rafael, 2010). The DNA molecule consists of 2 complementary strands in a helical structure where each strand serves as an informational template for the offspring during duplication (Rafael,…

Empty stomach, empty mind. Like a brimming bowl of Chipotle, a University of Chicago education is customizable, satisfying, and hearty. The familiar amalgamation of rice and beans, meat and vegetables is the essence of any Chipotle product. This delicious bowl, however, is flexible: whether it be mild, medium, or hot, every single bowl will always contain a type of salsa. These broad categories (meat, beans, salsa) diverge into a variety of options (carnitas, sofritas, pinto, black),…

Photography is not just strictly visual, it is influential, subjective, objective, and impactful. It is a means and a medium to bring about change in society or the world. The camera is a small but powerful tool to bring about social change but to also share an image, an image captured in a moment of time. In a quote by renowned American photographer Aaron Siskind, “Photography is a way of feeling, of touching, of loving. What you have caught on film is captured forever... it remembers little…

Rosalind Franklin was perhaps one of the most influential woman scientists. Rosalind Franklin was born in London, England on 25th July 1920. There is probably no other woman scientist with as much controversy surrounding her life and work as Rosalind Franklin. But now, the uncertain legacy of Franklin and her role in the 20th century 's premier biological discovery appears resolved in a new sweeping life story, Rosalind Franklin: Dark Lady of DNA, by British biographer Brenda Maddox. Brenda…

fraction of coir extract, concentration of metal precursor, contact time and solution pH on the formation of AuNPs was evaluated to determine the optimum conditions for synthesis. As synthesized AuNPs were characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray analysis…
