The improvement of deformability in AA7075 alloy through cryogenic treatment and its correlation with microstructural evolution and FE modelling.

Cryogenic treatment has high potential for improving the deformation behavior through the recrystallization at a low temperature. In this work, true stress-strain curves were obtained via compression tests to understand the deformation behavior of an AA7075 under cryogenic conditions. Results showed a significant improvement in the flow stress of AA7075, increasing from 260 to 560 MPa at the yield point.

Dual frequency ultrasonic liquid phase exfoliation method for the production of few layer graphene in green solvents.

In this work, we implement a dual frequency (24 kHz and 1174 kHz) ultrasonic assisted liquid phase exfoliation (ULPE) technique in deionized water (DIW) and other eco-friendly solvents, to produce a variety of high-quality few-layer graphene (FLG) solutions under controlled ultrasonication conditions. The resulting FLG dispersions of variable sizes (∼0.2-1.

Investigation of maternal serum endocan concentrations in pregnant women with gestational diabetes mellitus; a prospective case-control study.

Objective: We aimed to investigate the maternal serum endocan concentrations in pregnant women diagnosed with Gestational Diabetes Mellitus (GDM) and to investigate the usability of serum endocan in GDM screening.

Methods: This prospective case-control study was conducted with 160 pregnant women. The GDM group consisted of 80 pregnant women who had 75 g OGTT between the 24th and 28th weeks of pregnancy and were diagnosed with GDM.
