An electron vacancy is created and is further filled by an electron from the higher shell and thus an X-ray is emitted to balance the difference in energy between the two electrons. The detector placed on the energy dispersive spectroscope apparatus measures the number of emitted X-rays and their energies. Energy of the X-ray is characteristics of the element from which X-ray is emitted. A spectrum of the relative counts of the detected X-rays is obtained and evaluated for quantitative…

Voyage and Marvel’s Ant-man. Google is on the verge of making this scientific innovation a reality. Google representatives are teaming up with Stanford professors to be instrumental in this health identification creation. The idea is that the nanoparticles introduced into the body’s blood stream will be magnetic and a wearable device on the patient will transmit information on the reception of disease related cells. Currently, this medical procedure has only been used on artificial limbs.…

3D printing is a mechanical process where solid objects are created by ‘printing’ successive layers of material to replicate a shape modeled in a computer has been adopted in numerous industries. Many people can benefit from this kind of technology such as wounded warriors that may have lost limbs in combat, or even those that have dysfunctional organs and could use a new organ. The creator of 3D printing, Charles Hull, on August 8th 1984 filed for a patent on his photo solidification apparatus.…

ABSTRACT Current response of ascorbic acid-stabilized copper (Cu) single nanoparticles (NPs) collision on gold (Au) ultramicroelectrode (UME) surface was observed by the electrocatalytic amplification method. When the applied potential to the UME was 0.4 V, blip (or spike) response of current, which is responsible for the self-oxidation of Cu NP, was obtained. When the applied potential was over 0.5 V, the blip response combined with staircase response was obtained. The blip part indicates the…

Chapter-2 Preliminaries 2.1 Fluid Fluid is an any medium that possesses a capability of flow. It lacks a precise outline and assumes the shape of the vessel, in which it is positioned. Fluids can be further categorized in two groups. Liquids. Gases. Fluid mechanics Fluid mechanics deals with the mechanics of fluids and the forces acting upon them (liquids, gases, or plasmas). It can be divided into three sub-categories. Fluid statics. Fluid kinematics. Fluid dynamics. 2.2.1 Fluid Statics…

In this proposal, we report the design of two bioanalytical sensors: (1) a fluorescence optrode-based optical fiber sensor and (2) a carbon-based optically transparent electrode. The first provides a means for spatially organizing microorganisms to monitor their social behavior in response to different chemical environments. The electrode sensor enables the detection of signaling molecules that are responsible for, or a consequence of, sociomicrobial behavior. Upon their completion, these…

Targeting solid tumors - primary & metastatic - irrespective of their anatomical location in the body or pathological sub-type – and permeating drug molecules into the targeted tumor mass, will improve therapeutic outcomes and reduce life-threatening systemic toxicities induced by routinely administered chemotherapeutic regimens. Creating molecular dimension-specific temporary pores in the cell membrane using precisely computed, safe radiofrequencies (RF) from an external source, to…

say it is potentially because our room temperature could be the optimum temperature for this reaction to occur with the given plant’s catalase. In Preety and Hooda’s (2014) study, of immobilization and kinetics of catalase on calcium carbonate nanoparticles, her results showed that both enzymes showed an optimum temperature of 35C (p. 122). One could also say our hypothesis was falsified from the possibility the supernant was heated too much and a threshold was met to where the catalase was…

Prior to the serendipitous discovery of the first cisplatin anti-cancer complex in 1965 by Dr Barnett Rosenburg after studying unusual bacterial growth patterns, men with testicular cancer had limited medical options available to them with most of cases being fatal [1]. Results have now shown that, with an early diagnosis, over a ten-year age-standardised period net survival rate has increased from 69% in 1972, to 98% in 2011, in England and Wales [2]. Despite this breakthrough, cisplatin is…

Looking back on the modernization’s progress that we have in course of time, we can say that science is an essential element and have played a major role in building an advanced civilization as it is nowadays. Nowadays, we can see that lot of invention and scientific finding that are beneficial towards society. Of course, all the findings and invention are compiled through a scientific paper as a proof and compilation for the future generation’s references. The content of the successful research…
