Through these experiments the students discovered (not lectured) the principles of operations of these units, the effects of various parameters on their performance, and their pros and cons. The students' performance on the pre-and post-quizzes showed a significant improvement in students ...
In this respect, it is challenged by several experiments which have shown opposite trends for the activation energy by increasing the temperature [HAD 09]. The experimental results promote an interpretation of a return to ductility controlled by desorption. No mechanism is currently proven in LME....
20-inch Large area photomultiplier tube based on microchannel plate (MCP-PMT) is newly developed in China. It is widely used in high energy detection experiments such as Jiangmen Underground Neutrino Observatory (JUNO), China JinPing underground Laborato
That’s enough science and history for now. Let’s inject some fun into these conversations about solar energy with some more hands on games and experiments for kids.There are many solar energy activities for kids, so we’ve split it out into age group. Elementary School Go on anelectricity...
39 integrated the differential evolution algorithm (DEA) into GWO to update the previous best position of gray wolf \(\alpha\), \(\beta\) and \(\gamma\), so as to use the powerful search ability of DEA to make GWO jump out of the local optimum, and the experiments showed that , ...
(BET) analysis confirmed their substantial specific surface area. Electrochemical experiments demonstrated that the Co–N–C catalysts achieved the half-wave potential (vs. RHE) of 0.85 V in alkaline medium, overcoming Pt/C...
a demonstration of the incredible storage potential of a super capacitor. There’s a range of fuel cells to compare: PEM hydrogen fuel cell, the salt water fuel cell and a direct ethanol fuel cell. Countless experiments, so many scientific principles at work and plenty of space for creativity...
All experiments were performed in following Regulations for Animal Experiments and Related Activities at Tohoku University and the Animal Research: Reporting of In Vivo Experiments Guidelines. All efforts were made to minimize the number and suffering of the animals used. Animal preparations Male Sprague...
Zhong conducted the MD, density functional theory and Marcus rate calculations. W.K. solved the single-crystal structures. S.H.J. and F.R.L. analysed the molecular interactions in single crystals. Z.P. and H.A. carried out the GIWAXS and RSoXS experiments and corresponding analysis. ...
EW implemented the fuzzing framework and did the experiments. MR discussed the results and edited the article. Competing interests The authors declare that they have no competing interests. References 1. EU Commission Task Force for Smart Grids: Expert Group 1: Functionalities of smart grids and...
