Optical microscope and Electron microscopy were employed to evaluate the properties and morphology of the materials.
Introduction Phase change materials (PCMs) can store and release energy during phase change processes [1,2].
Microencapsulated phase change materials (MPCMs) not only have the ability of phase change from solid-liquid to presolid-solid in the meantime avoiding the influence of outside moisture, oxygen and other factors, but also can improve the stability of phase change materials.
Experimental (1) Materials and experimental equipment Low melt-point paraffin wax (Tsinghua university CP) was employed as core material.

However, most of these materials such as glass and ceramics are considered difficult-to-cut materials due to their high hardness.
Currently, Vibration-Assisted Machining (VAM) is found to be effective for machining difficult-to-cut materials.
Introduction Difficult-to-cut materials can be found in many vital applications such as optics and aerospace.

The performance of concrete materials under high temperature is more complex than that under room temperature.
This paper, by analyzing the mechanical property of concrete materials under high temperature(fire), probes into the changing law of the concrete materials' compressive strength under different temperatures (16 ˚C-800 ˚C) and different static placing time and makes a comparison on the concrete materials' strength between natural cooling and water cooling; illustrates the relationships of concrete materials' compressive strength and temperature, holding time and cooling and other factors under high temperature(fire).
Cool the above-mentioned concrete specimens and stand for a certain temperature environment for some time, and then have the compressive strength test of concrete materials; focus on the regular pattern of concrete strength influenced by temperature and cooling method.
