The present study reveals for the first time dry sliding wear behavior of a powder metallurgical pure titanium alloy (Cp-Ti) modified by shot peening. Cp-Ti samples were manufactured via metallurgy, and then their surface subsurface features using custom-made, fully automated shot-peening system. texture isotropy rate highest orientation angle shot-peened 71.5% 36°, respectively. Abbott curves ...

Exclusive chemical conversions of polyesters [poly(ethylene adipate) (PEA), poly(butylene (PBA), poly(ethylene terephthalate) (PET), (PBT)] to the corresponding monomers (diethyl adipate, diethyl terephthalate, ethylene glycol, 1,4-butane diol) by transesterification with ethanol using Cp’TiCl3 (Cp’ = Cp, Cp*) catalyst have been demonstrated. The present acid-base-free depolymerizations exhibit...

Laser powder bed fusion (L-PBF) process parameters can be changeable depending on the part geometry due to thermal conductivity differences. The number of studies parameter development for commercial pure titanium (Cp-Ti) with L-PBF is also quite limited in literature. aim this study present a comprehensive production Cp-Ti bulk and thin structures technology. In first phase, right parameters, ...

Supported amines are considered as adsorbents to replace aqueous amines for carbon capture and for CO(2) capture/conversion into chemicals. Here, amines are grafted to SiO(2) or Ti-SiO(2) by using aminopropyl triethoxysilane (APTES) or (3-triethoxysilylpropyl)-tert-butylcarbamate (TESPtBC) and then removing the carbamate group introduced by the latter by mild heating to 'deprotect' the amine. S...
