I have a few experiments that are on the top of my science list because they are easy to plan, prep and teach with little learners. One of the simplest experiments that my learners enjoyed so much was showing how clouds make rain. Time for Prep Some of the strangest things are usually ...
These space experiments and scientific research carried out with the returned samples have continued to achieve new results and will produce more important sci-tech and economic benefits through promotion, transformation and application, Lin noted. In the project on new materials carried out with high...
Experiments on spin–orbit torque magnetization switching over seven orders of magnitude in current pulse duration unveil a transition from non-coherent to coherent magnetization reversal as pulse duration is reduced and a reduction of energy consumption in the picosecond regime by an order of magnitude...
A cocktail of experiments and theory provides a way of revealing complex patterns in magnetic materials, including some textures that can identify the systems as members of an elusive class known as axion insulators. Youngjun Ahn &Liuyan Zhao ...
Experiments conducted on a smaller prototype simulator suggested drill resistance on the moon could be much higher than predicted by theoretical models, according to a paper by the Xuzhou team published in the Journal of China University of Mining and Technology last week. ...
There are plenty of experiments that melt ice with salt, but this one is a little different. Instead, it uses the heat produced by pressure to move a piece of wire through a block of ice. Learn more:Ice-melting experiment at KiwiCo ...

Whereas laboratory experiments are usually limited to certain factors. This is confirmed by Economides (2009), who states that the current testing procedure only measures the viscous drag effects on the proppant. In addition, these factors are still not much understood, which leads to studies being...
