English of High school curriculum is intended as a purposefully spiral ramp, which means students meet the same learning material three times with increasing difficulty during high school time. If students master this, it does not matter. Otherwise, it would be a big problem for them to continue their studies afterwards especially at university or at future work. I have chosen this topic in hope to help students be more confident in writing reports at medium or intermediate levels and then towards more difficult or advanced levels.

This Master's thesis aims to document the research process into the synthesis of 2D AlPO4 via a liquid metal synthesis pathway. The synthesised 2D AlPO4 will then undergo qualitative and structural analysis, after which it will be characterised via advanced techniques to determine piezoelectric characteristics, as well as the exploration of the ability of the synthesised material to absorb heavy metals.

The recent advances in the study of the unique capabilities of monolayer crystals had predicted piezoelectricity in two-dimensional (2D) group IV chalcogenides which are not present in their bulk forms. In this study, the predicted piezoelectric properties of was experimentally explored through Piezoelectric Force Microscopy (PFM). Tin Sulfide (SnS), Tin Selenide (SnSe), Germanium Sulfide (GeS), were exfoliated from their bulk forms by the top down methods of liquid sonication, while and Tin Disulfide (SnS2) mechanically exfoliated by tape.

Morphing wings were once in the common in early aviation however due to a lack of strong and lightweight materials they were abandoned in favour of conventional wings. Due to the recent advances in smart technologies, morphing wings has become of interest in aviation. This paper proposes the use of internal mechanisms to promote morphing in a wing to increase aerodynamic performance as opposed to the smart technologies. To determine the aerodynamic superiority of the morphing wing it was compared to a conventional wing of the same geometry.

This paper describes the preparation, optical properties and the role of the concentration of rare earth ions (RE: Eu, Er, Tb, Yb) as active centers in the energy transfer of Y2O3: RE nanophosphors. The materials are prepared by the combustion method using urea or glycine. Nanoparticles can be prepared with sizes ranging from 5 to 100 nm and can be estimated by high resolution TEM. Optimization of Eu and Er content in these nanophosphors was reported. The effect of energy transfer between Tb and Eu and the up-conversion between Er and Yb were studied.
