In this research, we had successfully prepared a series of RF-carbon nitride composites for photocatalyst application. The modification of carbon nitride with RF resins aimed to enhance physical characteristics and photocatalytic activity toward organic pollutants, such as methylene blue. XRD, FTIR, SEM, and N2 adsorptiondesorption isotherms were used to characterize the asprepared composite materials.

This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

The aim of this thesis was to investigate and characterise the effect on electron dosimetry that localising different forms of bolus, both approximately tissue equivalent and non tissue equivalent, in a non conventional, although reproducible locations, (ie not on the phantom surface). A series of experiments were derived to compare the differences in beam characteristics between the recognised conventional method of locating bolus on the surface to that of bolus supported by the Low Melting point Attenuator (LMA) Electron insert.

This study has adopted a systematic approach to identify the extent to which 20 kHz ultrasound affects the particle size and solubility of different protein solutions containing 4%, 7% and 10% whey proteins, caseins or a mixture at a range of energy densities (15-400 J/mL) and various pH (4.0-9.0). Milk proteins hold a prominent place in the food industry as they are used in many manufactured products for their functionality and most importantly nutritional benefits.

The investigation of magnetic field strength variations over subterranean layers may reveal their locations on Earth’s surface and provide physical and geometrical characteristics. Magnetic studies were carried out around Gölcük caldera lake using proton magnetometers to identify subsurface volcanic structures. The acquired data were inverted using four different edge detection algorithms such as analytic signal, tilt angle, theta map, horizontal gradient. Afterwards, the results were used to determine the locations of the anomalous structures.
