Gazi Üniversitesi Fen Bilimleri Dergisi, 2019 In this study, the effects of conventional quenching, deep cryogenic process and tempering treatment on microstructure, hardness and toughness impact energy of AISI H13 steel were investigated. For this purpose, the samples were subjected to conventional

Advanced Materials, EarlyView.Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

The Effects of Cryogenic Treatment on Cutting Tools
IOP Conference Series: Materials Science and Engineering, 2017 Enhancing the cutting tool life is important and economic factor to reduce the tooling as well as manufacturing cost. The tool life is improved considerably by 92 % after cryogenic treatment. The cryogenic treatment is a one-time permanent, sub-zero heat treatment that entirely changes cross-section of cutting tool.

High‐Performance Bio‐Glue From the Berries of a Parasitic Plant
Advanced Materials, EarlyView.We report a fully bio‐based adhesive derived primarily from a (poly)saccharide extract obtained from the berries of the hemi‐parasitic plant mistletoe (Viscum album), supplemented with tannic and malic acid without any further chemical functionalization.

Low‐Temperature Gold Deposition Improves CdTe Back Contacts
Advanced Materials Interfaces, EarlyView.Cd(Se,Te) samples are cooled during the evaporation of Au back contacts to thermally quench CdTe degradation. Reduced temperature during Au evaporation boosts PV efficiency, open‐circuit voltage, and fill factor. XPS associates these improvements with less chemical perturbation of the CdTe surface during metallization.
