Graphene for nanoelectronics Graphene shows a glaring ambipolar electric field effect such that charge carriers can be tuned continuously between electrons to holes. Single layer graphene atop a thermally grown SiO2 layer on a highly doped Si substrate may serve as a prototype of a field effect transistor. Under this configuration SiO2 serves as an […]
Recently, much attention has turned to the structural and electronic properties of carbon-based materials. At present, especially, graphene is the hottest topics in condensed-matter physics and materials science. This is because graphene has not only unusual properties regarding extreme mechanical strength, thermal conductivity and 2-diemensional films, but also peculiar electronic characteristics such as Dirac-particles with […]

Blood-material interactions are critical for the performance and biocompatibility of biomedical devices implanted in thousands of patients every day. When an implant is introduced into the body, protein adsorption and activation of complement proteins occur [1-3] and a series of interactions happen [4], firstly, water molecules reach the surface of the implant and build a […]
In this method, the temperature of 900–950°C and exposure time of 5 min are demonstrated to be suitable for the synthesis of graphene films on a nickel substrate, which is preferable to a copper substrate. It is indicated that the formation of graphene layers on the substrate occurs vertically along the flame height, with subsequent […]
X-ray diffraction (X-RD) technique has been ever adapted to recognize structural properties of materials and to get information like crystal structure/phase, lattice parameters, crystallite size, orientation of single crystals, preferred orientation of polycrystals, defects, strains and so on. The technique has found to be employed to study the thin films, bulk and nanomaterials [50]. Principle […]
Composite materials, as the name indicates, is a combination of at least two different materials combined together in a unit that has various properties. Namely, if a composite material is made out of different materials, then each material will keep its specific and unique properties- and this is what makes composite materials versatile and applicable […]
RESULTS Molecular identification of bacteria The 16S rRNA gene of the Oceanobacillus iheyensis strain was amplified using Polymerase Chain Reaction (PCR) with the help of 16S rRNA Universal primers. The 16S rRNA gene sequences were submitted to the BANK it and the ID number is (O. iheyensis _ MF192763). The Phylogenetic relationship was obtained using […]
Rosa Parks once proclaimed, I would like to be known as a person who is concerned about freedom and equality and justice and prosperity for all people. These same ideas could be spoken about Melba Pattillo Beals, a black girl who lived in Little Rock, Arkansas, an extremely segregated town. She was chosen as one […]
1.1 Municipal Sewage Sludge (MSS) Sludge consists of various elements such as waste, organic and inorganic compounds that are disposed into atmosphere which are harmful to the atmosphere. Sludge contains various pollutants and solid waste such as heavy metals, large organic solids, calcium and magnesium, metal sulphides, heavy metals organic complexes, precipitated soaps and detergents, […]
Abstract:In recent years, the cell membrane bionic nanoparticles as a new drug delivery system is widely used in small molecule drugs, vaccines and targeted delivery of macromolecular drugs, because of its inherited the specific receptors on the cell membrane and membrane proteins can be used to implement specific targeted delivery, and the tumor showed a […]
Introduction ‘US President Donald Trump has cast doubt on a report by his own government warning of devastating effects from climate change.’ (BBC News,26 November 2018) Several months ago, Donald Trump claims that the America exit ‘Paris Agreement’ because he think Global Warming is the lie of the scientists. Does he is true? The tables […]
Introduction Air pollution in urban areas has become an issue affecting human health to a degree unprecedented in human history. The World Health Organization (WHO) recently prioritized the reduction of air pollution, citing: An estimated 4.2 million premature deaths globally are linked to ambient air pollution, mainly from heart disease, stroke, chronic obstructive pulmonary disease, […]
Air pollution is a mixture of solid particles, such as car emissions and dust, and gases mixed in the air. It has many critical effects on a country as it may affect people’s health by causing severe asthma and heart disease. The principal cause of air pollution is the high emission of sulfur dioxide (SO2) […]
Air pollution is in continuously becoming a more important and researched topic in the science and health community. With statistics showing that 91% of the world’s population lives in a place where air quality exceeds the WHO guidelines it must be addressed. Air pollution can be easily understood by first looking at the main components […]

Overview This article discusses a study done at Penn state into the long-term affects of wastewater in disposal sites from fracking. In 2011, water and sediment downstream of fracking disposal sites was discovered to still contain unsafe levels of some chemicals, despite the water being treated, and had become radioactive. This had contaminated drinking water […]
Fracking is a Process that Oil Companies use to get Oil and other Natural Gases that are trapped in Shale Rock. The process involves using high pressured amounts of water, sand and a cocktail of chemicals which is called slurry through holes in an underground well pipe (Miller & Spoolman , 2019 ).This is done […]

Over the last ten years, America has experienced an energy revolution. Energy consumption has never been higher and the majority of this consumption is supplied by fossil fuels such as coal and oil or natural gas. In order to compensate the high energy demand, most conventional natural resources in the United States have been exhausted. […]
Photosynthesis is the process that transforms organisms from light energy into chemical energy. In order for photosynthesis to take place, it needs these three things: Water, carbon dioxide, and sunlight. As humans, in order to live plants, must take in gases. Plants are known as “”autotrophs, which means organisms that can make their own food. […]
To begin, the idea of photosynthesis was created by, according to Encyclopaedia Britannica, “”A Dutch scientist, Jan Ingenhousz. (Ingenhousz 1.) He was born in the Netherlands on December 8, 1730. Ingenhousz, is most known for his discovery of photosynthesis. According, to Encyclopedia Britannica, “”Ingenhousz discovered that light is necessary for photosynthesis, only the green parts […]
Presentation Photosynthesis, process by which green plants and certain different living beings utilize the vitality of light to change over carbon dioxide and water into the basic sugar glucose. In this manner, photosynthesis gives the fundamental vitality source to basically all life forms. A critical result of photosynthesis is oxygen, on which most living beings […]
