In this work, the applicability of spent coffee grounds as a starting material for production of pyrolytic carbon (PC) for application in bioelectrocatalysis was investigated. PC samples were prepared by pyrolysis of non-modified spent coffee grounds and coffee grounds impregnated with iron(II) nitrate as graphitizati…
The bronze alloys are expected to be used in bearings, bushings, propellers and wear plates in order to improve the performance of service. In order to have high service life, a research was conducted to analyse the titanium effect on the mechanical and wear properties of the bronze alloy. Alloys used in the present i…
This dissertation explores the study of magnetization dynamics in a ferromagnetic thin film and nanoscale ferromagnets. In bulk ferromagnets, nonlinear interactions generally couple each spin wave eigenmode to a continuum of other available modes through multi-magnon scattering. The multi-magnon scattering can potenti…

Biomaterials may be any class of material that aids in the regeneration, replacement, or augmentation of damaged tissues. The design of biomaterials is becoming increasingly sophisticated as new technologies enable the manufacture and incorporation of smaller components and structural features. Thus, a demand for equa…
This thesis provides insight into the chemistry of the BODIPY family of fluorophores. It describes the synthetic methods undertaken to attempt various structural modifications of the core BODIPY framework. Three different types of BODIPY themed molecules were targeted for synthesis; HBC-coupled BODIPY derivatives, met…
Analysis of the laser cut surface morphology remain topical. It is related with the fact that the surface roughness is the main index of the cut quality. The present paper deals with the experimental study of the relatively unstudied type of defects on the laser cut surface, dimples, or craters. According to the measu…

利用注塑机制备了PLA／PBS／秸秆粉可生物降解木塑复合样条，通过电镜扫描（SEM）和力学性能测试，探讨了不同含量的马来酸酐接枝聚乳酸（MAPLA）、5％硅烷处理秸秆粉以及2种相容剂同时加入对PLA／PBS／秸秆粉可生物降解木塑复合材料力学性能和断面微观结构形态的影响。结果表明：当MAPLA含量为5％时，弯曲强度和拉伸强度最大，分别为20．51MPa和19．03MPa，较未添加时分别提高了146．72％和118．07％。当MAPLA含量为3％时，冲击强度最大，为20．36kJ／m^2，较未添加时提高了36．19％。5％硅烷和5％MAPLA组合处理对PLA／PBS／秸秆粉木塑复合材料界面相容性有显著的改善，但对木塑复合材料力学性能的…
Cross-linking is a process in which polymer chains are associated through chemical bonds. Radiation, which penetrated through specimens and reacted with the cross-linking agent, gradually formed cross-linking (3D net), first in the surface layer and then in the total volume, which resulted in considerable changes in s…
Представлены результаты выращивания буферных слоев AlN для транзисторов с высокой подвижностью электронов методом высокотемпературной аммиачной молекулярно-лучевой эпитаксии с использованием Ga в качестве сурфактанта. Основными параметрами, влияющими на кинетику роста и дефектообразование, являются эффективные потоки…
Представлена новая технология формирования планарных сверхпроводниковых структур на основе пленок YBCO с металлическими контактами, полностью исключающая процессы травления. Нужная топология сверхпроводящих элементов из пленки YBCO создается предложенным методом "задающей маски". Омические контакты к сверхпроводящей с…
This thesis forms part of the Durban University of Technology Thermodynamics Research Unit’s project which is aimed at developing a method for determination of the liquid-liquid equilibria (LLE) data for the azeotrope {methanol + water} with an ionic-liquid (IL) using DSA5000M to assess the efficiency of the ionic liq…
This study provides details for the design, preparation of an environmentally friendly, clinically safe and lightweight radiation protective shield made ofGd2O3/epoxy nanocomposite (Gd-nanocomposite) which is proposed as an alternative to traditional toxic lead (Pb)-based aprons for diagnostic X-ray protection. In the…
Il rinnovato interesse nei confronti della cellulosa affonda le sue basi nella conoscenza approfondita oggi a disposizione sulla sua struttura cristallina e sulle sue proprietà. I film di cellulosa nanocristallina sono trasparenti e flessibili e prendono il nome di nanocarta. Essi potrebbero sostituire altri film pla…

Bis-[methyl-1-hydroxy-1-cyclopentene-2-dithiocarboxylate-O,S]nickel(II) 1 was prepared starting from methyl 2-hydroxycyclopent-1-encarbodithioate ligand (CPDT) and Ni(II), and catena-[(μ2-4,4′-Bipyril)-bis-(methyl-2-hydroxy-1-cyclopentene-2-dithiocarboxylate-O,S)]nickel(ΙΙ) 2 was prepared in good yields from 1 plus 4,…
This study investigates the effect of the non-uniform nuclide composition in spent fuel on material accountancy in the pyroprocess. High-fidelity depletion simulations are performed using the Monte Carlo code SERPENT in order to determine nuclide composition as a function of axial and radial position within fuel rods…
New hybrid materials were synthesized from an inorganic precursor, (tetraethoxysilane: TEOS) and bifunctional organic precursors through the sol-gel process. Indeed, monolithic and transparent hybrid gels were obtained by the reaction of tetraethoxysilicate (TEOS) with 1,2,4-thiadiazole-3,5-diamine (1), 5-amino-1,3,4-…
