Furthermore, treated particle GSP-recycled polyethylene composites were found to have higher strength as compared to untreated GSP. This is because the treated samples have higher interfacial bonding which occurred as a result of decrease in the hydrophilicity of the GSP   .
The Top Uses of Piezoelectricity in Everyday Appliions …
How Does Piezoelectric Material Work? Dating all the way back to 1880 and the groundbreaking work of brothers Pierre and Jacques Curie, the piezoelectric effect refers to the ability of specific materials — such as quartz, tourmaline, topaz and Rochelle salt — to produce an electric charge when subjected to mechanical stress.

What is Brazing and Soldering? | Radyne Corporation
What is Brazing and Soldering? Definition of Brazing, Soldering and Welding According to the Metals Handbook 9 th ed., welding is “a material joining process which produces coalescence of materials by heating them to suitable temperatures, with or without the appliion of pressure or by the appliion of pressure alone, and with or without the use of filler material” (Ref. (1)).

Metal Strength and Stiffness: What’s the Difference?
A material can have high strength and low stiffness. If a metal cracks easily, it has low strength, but if it has low stiffness, it can deflect a high load. The article explains that stiffness depends on the modulus of elasticity, also known as Young’s Modulus, which is constant for a given metal.
