Alternatives to hard chromium plating on piston rods

As a main part of hydraulic cylinder, the piston rod is used in tough surrounding and corrosive condition; consequently a high quality protecting layer is essential. Currently EHC, electroplating hard chromium (hard chrome) is a widespread method for piston rod due to powerful performance and low cost. Unfortunately the plating process contains hexavalent chromium (Cr) which is toxic and carcin...

Ibuprofen-Loaded CTS/nHA/nBG Scaffolds for the Applications of Hard Tissue Engineering

Background: This study addressed the development of biodegradable and biocompatible scaffolds with enhanced biomechanical characteristics. The biocompatibility and the cationic nature of chitosan (CTS) make it more effective as a bone grafting material. Methods: The hydroxyapatite nanoparticles (nHA) were synthesized by hydrothermal method, and bioglass (nBG) (50% SiO2-45% CaO-5% P2O5) was synt...

Canalization and environmental engineering

Canalization is an umbrella term a leading C. H. Waddington introduced in 1960’s. The term describes the ability of a population to buffer disturbances in phenotypic development. There are two major types of canalization based on the sources of disturbances: genetic and environmental. Genetic canalization describes the ability to express the same phenotype from different genotypes, while enviro...
