The main purpose of this work is to produce activated carbon from local agricultural waste by-product such as Cocos Nucifera L. (coconut) husks and Musa Paradisiaca (banana) peel. It will be synthesized through two (2) different methods which are carbonization and activation process. Coconut husks and banana peel will…
Исследованы линейные и нелинейные диэлектрические свойства композитов на основе KIO3 и нанокристаллической целлюлозы Acetobacter Xylinum. Обнаружено повышение температуры структурных переходов IV → III и III → II на 20 и 24 K, соответственно, для иодата калия в порах нанокристаллической целлюлозы относительно соответс…
Biodegradowalne materialy polimerowe stosowane są obecnie w wielu galeziach przemyslu, stanowiąc przyjazną środowisku alternatywe dla konwencjonalnych tworzyw sztucznych wytwarzanych z paliw kopalnych. Wzrost liczby zagranicznych i krajowych prac badawczo-rozwojowych nad nowymi iodegradowalnymi materialami polimerowym…

The assessment of radionuclides in selected granite quarry sites in Ohimini and Gwer-East Local Government Areas of Benue State was carried out using a 76 × 76 mm NaI (TI) detector crystal optically coupled to a photomultiplier tube (PMT). The detector is enclosed in a 6 cm lead shield with cadmium and copper sheet an…
The aim of the research is providing the application method of recycled materials to manufacture the low costed eco-friend block at currently operated concrete block plant. In this research, based on the previous research results on three types of slag cement with illite, desulfurized gypsum, and wasted refractory pro…
We implement a phase field method for the analysis of ferroelectric thin films with the aim of investigating the effect of grain orientation.We present some benchmarks with literature examples and finally discuss a preliminary investigation of a multigrain structure highlighting its impact on the size and shape of the…
V teto praci byla zkoumana možnost syntezy dvourozměrných nanocastic grafenu v plynne fazi. Použili jsme mikrovlnný plazmový plazmový výboj (2,45 GHz, 210 W) pracujici za atmosferickeho tlaku za ucelem syntezy nanocastic uhliku s obdelnikovým tvarem a typickou velikosti stovek nanometrů. Výboj hořaku byl zapalen argon…
In this study, the green synthesis approach was adapted to synthesize silver nanoparticles (AgNPs). The prepared silver nanoparticles were characterized by UV- Visible spectrophotometer, X- Ray Diffraction (XRD), X- Ray Fluorescence (XRF) and Fourier Transformation Infrared (FTIR) respectively. The UV- Vis spectra of…
Vertically oriented graphene nanosheets (VOGN) synthesized by radio frequency plasma enhanced chemical vapor deposition (RF-PECVD) have been fabricated as electrical double layer capacitors (EDLCs). The relatively open morphology of the films provided good frequency response, but had limited capacitance compared to pr…
Blends containing methoxyoligooxyethyleneglycol (MPEGs) (MW 350 and 550) and bis(trifluoromethane)sulfonimide lithium (LiTFSI) salt were prepared by solution blending process using tetrahydrofuran (THF) as a solvent. The ionic conductivity of the blends of different compositions were determined at four temperatures i.…
In this study, hybrid composites of kenaf fiber mat (KFM) and glass fibre mat (GFM) reinforced unsaturated polyester (UPE) composites were prepared by using hand lay-up technique and continue with compression moulding. The KFM was chemically treated with hydrogen peroxide (H2O2) at 6% in order to improve the interfaci…
This work is aimed at describing the feasibility of the use of biomacromolecules (such as proteins and nucleic acids) as sustainable flame retardant coatings for textiles and also plastic materials. In fact, such compounds as caseins, hydrophobins, whey proteins and nucleic acids could represent a valuable potential a…
In the present work, a dynamic lumped parameter model of the electrochemical and thermal behavior of a Solid Oxide Fuel Cell (SOFC) has been developed. The model is implemented in the MATLAB-Simulink visual programming software. The model was calibrated using experimental data. A strategy is proposed for the thermal m…
Composite laminates present important advantages compared to conventional monolithic materials, mainly because for equal stiffness and strength they have a weight up to four times lower. However, due to their ply-by-ply nature, they are susceptible to delamination, whose propagation can bring the structure to a rapid…
Denna rapport ar en del av ett projekt med det overgripande malet att bygg- och rivningsavfall i hogre utstrackning skall atervinnas eller ateranvandas. Detta utan att kvaliteten pa materialet, och ...
Lo scopo dello studio è quello di classificare campioni di pasta di grano duro sfruttando le informazioni fornite da composti del profilo aromatico riconducibili alle condizioni termiche adottate per l’essiccazione della pasta. Il set di campioni è costituito da “Pasta di Gragnano” IGP e paste dei più comuni marchi…
Tato bakalářská práce se zabývá kationtovou polymerací barev/laků indukovanou diodami emitujícími záření v UV oblasti (UV LED). Experimentální část je zaměřena na vytvrzování epoxidového pojiva Uvacure 1500 s třemi typy kationtových fotoiniciátorů (železoarénový iniciátor Irgacure 261, iodoniový iniciátor Irgacure 250…
