Assessment of dyeing and some fastness properties of nanocrystalline cellulose extracted from corn cob

BUKHARI M. M^*, SALEH YUSUF MAIGARI, ATTA A. Y, Mohammed K. Yakubu

The dyeing of nanocrystalline (NCC) cellulose powder extracted from corn cob (Saleh, 2015) was carried out using Reactive (Procion Violet H-3R), Disperse (Foron YellowS.E 2GL) and Direct (Solophenyl Yellow) dyes. The percentage exhaustion in each case was calculated to determine which of the dyes exhausted best. The fastness of the dyed NCC powder to washing, chlorination and light were also i...

Investigation into the Admixture Properties of Bone Ash: A Focus on Setting Time of Ordinary Portland Cement

Mtallib M.O.A.^*, Tijjani D.

This paper reports the findings of an investigation into the admixture potential of bone ash (BA) with a focus on the setting time of ordinary Portland cement (OPC). Cow bones are agricultural waste and constitute a sizeable proportion of solid waste in many cities of the world. Heaps of cow bones constitute aesthetic problem to the environment, unnecessary occupation of space and exude unpleasant...

Bleaching of atili (blackdate) oil for use as white oil

MAINA N. S^*, AMEH A. O, EDOH O.

Atili (blackdate) oil was bleached in this research using three different adsorbents; acidic fuller’s earth, activated carbon, and the mixture of fuller’s earth and activated carbon. The adsorbents were compared to give the most suitable of the three. The bleaching process was carried out by agitation of varying amounts of the different adsorbents at 80oC and a contact time of 45mins. The bleac...

Mineralogical and Chemical Evaluation of Agbaja Fireclay for Industrial Applications

Abdullahi, Y.^*, Gonah C. M.

To evaluate the potential of Agbaja clay for industrial applications, a comprehensive analysis of its physico-chemical and mineralogical properties was undertaken. The clay exhibited a predominantly kaolinitic composition, as determined by X-ray powder diffraction (XRD), with halloysite and illite as minor constituents. The chemical analysis revealed significant alumina (Al₂O₃) and silica (SiO₂) c...

GC-MS analysis of bioactive compounds from the fruit pulp and seed extracts of Diospyros mespiliformis(Jackal beery)

MANN A^*, TIJJANI A., GARBA K.

Diospyros mespiliformis is ubiquitously found plant in northern Nigerian farms and forests. Previously, various parts of this plant were reported for treatment of different types of diseases and there was neither a report of collection of the plant’s fruit pulp and seed from Dutsin-Ma nor on GC Ms analysis. Preliminary phytochemical screenings of n-hexane and methanol extracts were carried out ...

Effect of Nanoclay Loading on the Hardness Property of Epoxy Composites

Egere B.C^*, Yusuf L.O, Abdulkadir Suleiman Abdulrahman

This study examines the influence of nanoclay loading on the hardness properties of epoxy composites. Nanocomposites were fabricated using varying weight percentages of nanoclay and epoxy via the hand layup method with an open mould. Mechanical characterisation was carried out using a Rockwell hardness tester, while the dispersion and morphology of nanoclay particles within the epoxy matrix ...

Physical properties of subgrade soils from Nigerian highway master test section 1 (Kano-Kaduna region)

Murana A A^*, OLOWOSULU A T, JOEL M

Subgrade materials from Master Test Section (MTS) 1 were tested to obtain their physical properties. Three samples each from the MTSs making a total eighteen (18) samples were obtained and subjected to laboratory test to determine their basic physical properties. Testing include particle size distribution, Atterberg limits and specific gravity tests. The samples were classified according to Ame...

Evaluation of the Effect of Starch as Binder in Sand Casting of Aluminium

Adamu M. A^*, Ikhianfia G. O., Mijinyawa A. A, Abdulkareem B, Ibrahim A. A.

This study focuses on evaluating the effectiveness of cassava starch as an organic binder in sand preparation for aluminium casting, emphasising its influence on key mould properties, moisture content and green compressive strength and overall casting quality. Silica sand mixtures were prepared with cassava starch at 7.5%, 10%, and 12.5% by weight, molded into cylindrical samples, and tested fo...

Agronomic Usefulness of Anaerobic Slurry on Tomato (Lycopersicum Esculentum) Seedlings

Maliki Muniratu^*, Esther Uwidia Ikhuoria

Current anaerobic digestion technologies are geared towards maximizing biogas yield and the subsequent use of the anaerobic slurries as soil amendments. However, only few studies have established the agronomic risk associated with the utilisation of anaerobic slurries. Therefore, this study evaluates the effect of agronomic use of anaerobic slurry on lycopersicum esculentum seedlings. L. escule...

Photo-Degradation of Direct Yellow 96 In UV/TiO2 and UV/H2O2 using Factorial Design

Okeme A. C.^*, Kogo A. A., Nurudeen Yusuf., Abdulraheem Giwa

In this research, factorial design have been employed to study the influence of four important factors; pH, catalyst dosage, irradiation time and dye concentration in the treatment of C.I. Direct Yellow 96 dyestuff using UV/TiO2 and UV/H2O2 photo-degradation processes. The results indicate that the adsorbent dosage and irradiation time exhibit a significant positive effect on the efficiency of ...
