The wide investigation of zinc oxide (ZnO) nanorods is primarily driven by their exceptional utility in several industries, such as solar cells, sensors, photodetectors, photocatalysts, microchip technology, and piezoelectric transducers. There has been a growing focus in environmental defense applications on the use of ZnO nanorods as photocatalysts.

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).

Multimetallic nanocatalysts have remarkably revealed activities in various catalytic applications. Herein, the ternary nanocatalysts based on palladiumvanadium-cobalt were successfully synthesized through the reduction of their salts with sodium borohydride including impregnating of activated carbon (AC) substrate with colloid solution of metallic nanoparticles (PdVCo/C).

TiO2 thin films were synthesized by using Chemical Vapor Deposition (CVD) method on different substrates, such as glass, aluminium foil , and ceramic. The samples had been characterized by microscopy analysis, SEM, and EDS. The results show that TiO2 thin films were successfully fabricated and TiO2 nanocrystals with size of 50-100 nm loaded uniformly on surface of different substrates.

Zeolite Socony Mobil-5 (ZSM-5) was successfully synthesized by a hydrothermal method from the silicon dioxide (SiO2) precursor prepared fro m rice husk ash. Titanium dioxide (TiO2) nanoparticles were decorated on ZSM-5 substrate by a sol-gel method. ZSM-5/TiO2 materials were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscope (TEM), and Brunauer-Emmett-Teller (BET) surface area analysis.

The plasmon characterization of AgNS on paper was systematically investigated by the diffuse reflectance spectroscopy. The fabricated paper-based SERS substrates were used to detect melamine in an aqueous solution and to determine the influence of type RAs on the enhancement factor (EF) and signal uniformity of SERS substrates. Among the four types of RAs, the SERS substrates used NaBH4 have the highest SERS signal with the limit of detection of 10-8 M for melamine and the EF = 2.3 × 109 .

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.

In this study, the content of As, Cd and Hg in fruiting bodies was determined. These three elements were determined in 94 Macrolepiota procera (Scop.) Singer samples (separately for caps and stems) and their corresponding soils/substrates collected from 8 different localities in Slovakia. Arsenic and cadmium were analyzed by Optical Emission Spectrometry with Inductively Coupled Plasma (OESICP), and mercury by Advanced Mercury Analyzer (AMA-254). In the soil/substrate As content varied from ND (not detected) to 11.9, Cd from 0.66 to 22.9 and Hg from 0.02 to 0.
