This study was designed to experimentally measure the thermal and electrical conductivities of Aluminium Nitride/Ethylene Glycol (AlN/EG) nanofluids. Transmission electron microscopy (TEM) was used to characterize the shape of AlN nanoparticles. Nanofluids with different particle volume concentrations of 0.5%, 1%, 2%, 3%, 4%, and 5% were utilized. The thermal and electrical conductivities of the...

This study aims to determine the effectiveness of author's teaching technology in developing schoolchildren's research skills, challenges an elementary school faces, and how entire process skills works. Quantitative qualitative techniques were used. Participants from No.15, No.1, No.46, No.16 schools Ust-Kamenogorsk (East Kazakhstan). A random selection was made EG comprising 176 students a CG ...

It has been well known that doping nano-scale catalysts can significantly improve both the kinetics and reversible hydrogen storage capacity of MgH2. However, so far it is still a challenge to directly synthesize ultrafine (e.g., < 5 nm), mainly because complicated chemical reaction processes. Here, facile one-step high-energy ball milling process developed in situ form Ni nanoparticles from ni...

Chlorpyrifos is an organophosphate insecticide, used to control foliage and soil-borne insect pests on a variety of food and feed crops. In the natural environment, Chlorpyrifos can be degraded  through  several  possible  processes,  including  photodegradation, biodegradation,  and hydrolysis.  In  the  present  work  the  photodegradation  and  environmental  fate  of  Chlorpyrifos  in aqueo...

Background: The development of a reliable method for the cryopreservation of mammalian ovary would be an important advancement in the field of reproductive biology for the preservation of genetic resources. The cryopreserved follicles have the potential to develop in-vitro; however, the developmental rate is lower than that of fresh follicles. Researchers have used that of different cryoprotect...

Self-regulation is the ability to regulate one’s cognition, behavior, actions, and motivation strategically and autonomously in order to achieve self-set goals including the learning of academic skills and knowledge. Accordingly, self-regulated learning involves self-generated and systematic thoughts and behaviors with the aim of attaining learning goals. With that in mind, this study aimed to ...
