Aging In Air

Because of its good corrosion resistance and biocompatibility, superelastic Ni–Ti wire alloys have been successfully used in orthodontic clinics. However, delayed fracture in the oral cavity has been observed. The susceptibility of a Ni–Ti shape-memory alloy toward hydrogen embrittlement has been examined with respect to the current densities and aging in air at room temperature. Orthodontic wires have been cathodically hydrogen charged using a different current density of 5, 10, and 20 A/m2 from 2 to 24 h in 0.9% NaCl aqueous solution at room temperature. The critical stress for the martensite transformation under a monotonous tensile test has been 20–90 MPa higher than that without hydrogen charging. In addition, embrittlement takes place in the austenite–martensite transformation plateau. For a short period of charging, the Ni–Ti alloy conserves its superelastic behavior. However, after 24 h of aging in air at room temperature, fracture at the austenite–martensite transformation plateau takes place earlier.

Given the fact that solvothermal synthesis is the most common synthetic method to obtain metal–organic frameworks (MOFs) on a gram scale, it still remains a great challenge to produce MOFs in a scalable and sustainable synthetic process.

Capture Capacity

A new CO2 absorber is reported in this paper. When CoCl3 is mixed with propylenediamine at room temperature and atmospheric ambient pressure, the extremely low concentration of CO2 in the air can be absorbed to form a stable metal complex [Co(PPD)2CO3]Cl·H2O (PPD = 1,3-propylenediamine). The CO2 capture capacity can reach 23.6 wt. %. Although Co is relatively expensive, the practical use of cobalt metal complexes produced still needs to be developed. This study provides an idea of capturing CO2 at low concentration under normal conditions. Through the structural characterization and performance study of complex [Co(PPD)2CO3]Cl·H2O, a new method for CO2 capture was explored. Thermogravimetric analysis data show that the compound [Co(PPD)2CO3]Cl·H2O has the ability to desorption CO2 and H2O at 160-220 ºC, and the ability to adsorb CO2 or regenerate CO2 is being explored. The electrochemical property of compound [Co(PPD)2CO3]Cl·H2O were also investigated.
