Article Synopsis
- β-tricalcium phosphate (β-TCP) is an effective and biocompatible material for bone deficiency treatment, enhanced by doping with strontium (Sr) and silver (Ag) ions.
- Researchers prepared β-TCP powders with varying amounts of Sr and Ag, then sintered them at high temperatures before testing their properties in simulated body fluids.
- Results revealed that Sr and Ag doping affected the samples' structural characteristics, and while compressive strength generally decreased after degradation, the doped samples showed promising osteogenic potential for bone repair applications.

With the development of the precision manufacturing industry, actuators' performance requirements are increasingly demanding. However, stick-slip actuators still have the problems of backward motion and low motion speed at low frequencies. In this paper, to decrease the backward motion and achieve high speed at low frequencies, a linear piezoelectric stick-slip actuator is designed based on the two-stage lever principle.

Natural cellulosic fibres have significant potential as reinforcements to replace synthetic fibres applied in biopolymer composites. A natural cellulosic fibre was extracted from corn stalk waste and then it was treated by silane solution with different concentrations. The influences of silane on chemical, surface morphological and mechanical performances of Corn Stalk Fibre (CSF) as well as impact strength and impact fracture surface morphology of CSF reinforced polymer composites were evaluated in the present work.

In this work, a miniaturized device based on a bionic piezoelectric actuator was developed to investigate the static tensile and dynamic fatigue properties of bulk materials. The device mainly consists of a bionic stepping piezoelectric actuator based on wedge block clamping, a pair of grippers, and a set of precise signal test system. Tensile and fatigue examinations share a set of driving system and a set of signal test system.
