In recent years, the prediction of the effective transport properties have received a great number of investigations. The present work is dedicated to determining the effective permeability of two-dimensional (2D) doubly porous materials made of an isotropic permeable solid matrix in which elliptical shaped pores of any size are embedded.

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.

The main aim of this thesis is to investigate a novel synthesis route to produce 2D bismuth-based nanosheets from liquid bismuth precursors by exfoliating their interfacial oxide. Scalable and large-area synthesis of 2D nanosheets will be developed to access previously inaccessible 2D bismuth-based nanosheets from the non-layered bulk parent material. Subsequently, the as-synthesis 2D nanomaterials will be investigated for different functional applications.

In this work, the adsorption ability of β12 borophene towards some main harmful gases was investigated. The first-principles calculations were employed to obtain the adsorption configurations and the adsorption energies of CO, NO, CO2, NH3, and NO2 on 12 borophene. The vdW interactions are taken into account by using three functionals: revPBE-vdW, optPBE-vdW, and vdW-DF2.

Large-pore three-dimensional (3D) mesoporous silicas are among the most interesting mesoporous materials discovered in recent years, and they have attracted much attention for potential applications requiring easily accessible, uniform and large pores. Examples of these are SBA-15 (p6 mm) and SBA-16 (Im3m), which have cylindrical- and cage-type structures, respectively.
