High Entropy Alloy Nitride Hard Coatings Prepared by Cathodic Arc Deposition and Their Applications of Micro End Mills
Summary | The technology uses cathodic arc deposition combined with electromagnet field control and optical emission spectroscopy (OES) for the deposition of new functional high entropy alloy (HEA) nitride coatings. The HEA nitride coatings possessed such high hardness and excellent hydrophobicity with low surface energy which are beneficial for high speed dry cutting. Finally, the coatings were deposited on the micro end mills for cutting test of printed circuit board. The HEA ACZN coated tools can possess high wear resistance and outperform the uncoated tools at least 4 times of tool lives. The technology uses cathodic arc deposition combined with new electromagnetic field control and optical emission spectroscopy (OES) for the deposition of new functional high entropy alloy (HEA) nitride coatings.

Mitochondrial Analytic Platform and Nucleotide Applications
Summary Description: 1. Stress alters mitochondrial import of proteins. To monitor changes in mitochondrial import at single-mitochondrial resolution, split GFP epitopes are fused to the target proteins and mitochondrial membranes or expressed in the mitochondrial matrix. 2. General genotoxic agents damage both nuclear and mitochondrial DNA. By expressing mitochondrial DNA binding protein TFAM fused with KillerRed, specific mitochondrial DNA damages by light exposure are induced for investigating mitochondrial DNA damage signal. 3. Quantification of four dNTP pools is important for understanding drug action. The popularity of the analysis has been limited by the requirement of radio-isotope or sophisticated instrumentation. The method of click reaction we designed for measuring dNTPs overcomes the drawbacks of conventional methods. 4. The outbreak of drug-resistant Candida infection in hospital is of concern. We found the distinct biochemical property of Candida TMPK in high affinity to uridylate as the substrate, leading to the discovery of 5FUd (<5 nM) in suppressing Candida growth.

Modular Friction Stir Welding Tool Holder
The technology designs a modular friction stir welding tool holder. This welding tool holder integrates a variety of functions, including constant pressure welding, temperature monitoring, removable FSW tool design, and can be clamped to an existing CNCmachine. The advantage is that it can realize the function of automatic exchange for friction stir welding and CNC milling in one machine. Breaking through the previous friction stir welding, you need to buy a friction stir welding machine, which is expensive to obtain.
