Production of biodiesel from sludge palm oil by esterification using P-toluenesulfonic acid by Hayyan, Adeeb, Alam, Md. Zahangir, Mirghani, Mohamed Elwathig Saeed, Kabbashi, Nassereldeen Ahmed, Mohd Siran , Yosri, Mohd. Hakimi , Noor Irma Nazashida

“…Batch esterification process of SPO was carried out to study the influence of PTSA dosage (0.25-10% wt/wt), molar ratio of methanol to SPO (6:1-20:1), temperature (40-80oC), reaction time (30-120 min). The effects of those parameters on FFA content, yield of treated SPO and conversion of FFA to FAME were monitored. …”

Heavy metals removal from synthetic wastewater by a novel nano-size composite adsorbent by Onundi, Yusuf Bamidele, Al-Mamun, Abdullah, Al-Khatib, Ma'an Fahmi Rashid, Al-Saadi, M. A., Muyibi, Suleyman Aremu

“…Experimental conditions resulting in optimal metals adsorption were observed at pH 5, 1 g/L dosage and 60 min contact time. It was noted that the percentage of metals removal at the equilibrium condition varied for each metal, with lead recording 99 %, copper 61 % and nickel 20 % , giving metal affinity trend of Pb2+ > Cu2+ > Ni2+ on the adsorbent. …”

An investigation of hole quality during drilling of carbon fibre reinforced plastic and titanium (Ti6Al4V) using tungsten carbide drills by Dahnel, Aishah Najiah, Ascroft, Helen, Barnes, Stuart

“…The drilling trials were conducted through CFRP/Ti stacks, CFRP-only and Ti-only using carbide drills (6.1 mm diameter) at a cutting speed of 50 m/min and a feed rate of 0.05 mm/rev. The quality of the drilled holes was evaluated with respect to the hole diameters, delamination and pull-out of CFRP as well as Ti burr. …”

CONSERVATION OF NATURAL RESOURCES: UTILIZATION OF SEWAGE SLUDGE IN BRICK AND ITS IMPACT ON GAS EMISSIONS AND INDOOR AIR QUALITY by Nurul Salhana, Nurul Salhana, ABDUL SALIM, ABDUL SALIM, ABDUL KADIR, Aeslina, MOHAMED NOOR, Norazian

“…The bricks were incorporated with two types of sewage sludge (0% and 5%), fired at 1050ºC with 1ºC/min as its heating rate. The X-ray fluorescence (XRF) test was conducted to determine the characteristics of the sewage sludge and clay soil. …”

Effect of sugar palm fibers on the properties of blended wheat starch/polyvinyl alcohol (PVA) -based biocomposite films by A.B.A. Mohammed, Abdulrahman, Hasan, Zaimah, A. Borhana Omran, Abdoulhdi, M. Elfaghi, Abdulhafid, Hassan Ali, Yasir, A.A. Akeel, Norie, Ilyas, R.A., Sapuan, S.M.

“…It has been found that reinforcing plasticized starch/PVA matrix with palm fibers has considerably enhanced physical properties, the density of the polymer declined to 1.21 g/cm3 with untreated fibers and to 1.32 g/cm3 with treated fibers, which created a lighter weight bioplastic, and a reduction occurred in water absorption (for example 3% of treated fiber showed 143% absorbed water after 30 min immersing in water) and water solubility. When compared to the films without fibers filler, films reinforced with fibers demonstrated a c3onsiderable improvement in the crystal profile; at 9% fiber load, it improved over double. …”
