This work reports the deposition of a dense α-Ta and β-Ta films to enhance the surface hardness and biocompatibility of Ti by applying a different negative substrate bias during direct current (DC) sputtering. When a Ta film was deposited with a negative substrate bias voltage of 70 V, the microstructure of the film exhibited a single β-Ta phase.

Lead-free barium titanate based Ba1-xSrxTiO3 thin films (x = 0 ÷ 0.45) have been deposited onto Pt/Ti/SiO2/Si(100) substrate via sol–gel technique. The films were crystallized at temperature of 650 °C for 30 min in the air. The experimental data displayed that microstructure, dielectric and ferroelectric properties of the films were strongly influenced by the Sr concentration.

Polyethyleneimine (PEI) is a novel polymer that contains multiple amine groups that are suitable for chelation with many heavy metal ions (HMI). Anchoring PEI onto the surface of a solid substrate has been widely adopted to develop adsorbent materials with the hope of combining the HMI chelating ability of PEI with the heterogeneity of the substrate.

Fertilizers play an important role in enhancing crop yield, plant growth, and the fertility of the soil. This research was conducted at the Faculty of Agriculture Teaching and Research Farm, University of Port Harcourt, Nigeria to investigate the influence of inorganic fertilizer (urea) and organic manure (spent mushroom substrate and poultry manure) on the yield and growth parameters of three okra cultivars (Clemson Spineless, Perkins Long Pod, and a local assertion).

This study involved the deposition of NiO thin films onto Al2O3/glass substrates using RFmagnetron reactive sputtering. Then, the influence of heating temperatures on crystal structure, surface morphology, transmittance, and optical band gap of NiO films was investigated via different characterization techniques.

This experiment aimed to synthesize isoamyl acetate and understand preparing ester’s mechanism. The test compounds underwent reflux, distillation, extraction and vacuum filtration. Through an acid, acetic acid could serve as a substrate. This could easily be attacked by isoamyl alcohol, thus producing isoamyl acetate.

Adsorbents functionalized with polyol are considered to be effective for the removal of boron from aqueous solutions. In this work, polyol-functionalized chitosan particles were successfully synthesized. Batch experiments were conducted for the determination of the optimal conditions for the highest degree of gluconated groups being grafted to chitosan substrate.

This research focuses on Fibre Cement Felts (FCF), which is a non-woven textile substrate acting as a conveyor belt for the manufacturing of Fibre Cement Sheets (FCS). Fibre Cement Felts are a valued component required in the manufacturing process of Fibre Cement Sheets, used in construction for today’s building industry. Identifying the key factors that most influence FCF will assist in understanding of the relationship between fibre diameters, carded web, and mechanical bonding.

As science and technology has developed, the manner by which drugs can be delivered has grown. Medicines may be taken orally, applied as topical pastes, creams or oils, patches or administered by direct injection to the body. This research explores an alternative method for the delivery of therapeutic compounds to the body. The basis of the study involves the application of traditional medicinal compounds used to cure minor neck and back pains through transdermal topical application, using a textile substrate as the carrier.

The aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

This thesis has two key results, a study on the effect of carbon in electron-beam deposited platinum nano-wires and a novel temperature sensing glass substrate for marker-free thermometry. The thesis focus on the effect of carbon contamination in plasmonic nano-wires composed mainly of platinum produced from FEBID. Because carbon acts as an insulator in the platinum/carbon composite, we model the effect of carbon impurities by reducing the charge carrier concentration inthe platinumwire.
