Effect of different configurations of hybrid nano additives blended with biodiesel on CI engine performance and emissions.

The use of nano additives to improve the cold properties of biodiesel is encouraged by its drawbacks and incompatibility in cold climate. Waste cooking oil (WCO) was transesterified to create biodiesel. A 20% by volume was used for combination of diesel and methyl ester.

Enhancing bio-oil yield extracted from Egyptian castor seeds by using microwave and ultrasonic.

Energy scarcity and conventional energy problems are the main reason of finding a renewable source of energy which is cheap and environmental friendly, therefore, biodiesel production is one of the most promising solutions of this problem. Also, Egyptian castor is one of the most important crops for oil production compared with other commonly used oil crops. The main aim of this study is to enhance the production of bio-oil from Egyptian castor seeds by using microwave and ultrasonic as pre-treatments.

Smart prototype for an electronic color sensor device for visual simultaneous detection of macrofuran based on a coated paper strip.

Nowadays, in the clinical, pharmaceutical, and environmental sectors, the development of facile and sensitive analytical methods and/or innovative devices for the follow-up and detection of antibiotics and pharmaceutical formulations, in general, are urgently needed and still challenging. This work declared three vital applications for broad-spectrum nitrofurantoin (macrofuran) antibiotic detection and quantification: A colorimetric method, a coated paper strip-based nano-lanthanum complex prototype and fabrication of smart electronic color sensor device-based coated paper strips. The colorimetric method showed a significant response upon increasing the concentration of the nitrofurantoin in a range between (1.

Influence of heat treatment on the mechanical and the lubricant wear characteristics of stainless-steel grades against 5 wt% NaCl as industrial shielding materials.

This article investigates the impact of the heat treatment, and lubricant wear measurements at 5 wt % NaCl solution, mechanical and radiation shielding properties of three grades of stainless steels: SS316, M303, and SS201. The obtained results showed that heat-treated martensitic stainless-steel grade has improved mechanical and tribological properties while heat-treated austenitic stainless-steel grades showed deteriorated wear resistance. The radiation shielding parameters of the studied grades are comparable.
