CNC: Reduce runout with ANCA's new complete tool runout compensation

Manufacturing high-quality, high-performance tools requires the Total Indicator Runout (TIR) to be perfect or minimal for overall tool life and surface finish. Runout can cause shortened tool life and poor surface finish, and in drills and reamers can result in oversized holes. A new option in ANCA's ToolRoom cures runout woes and helps to increase tool life and productivity.

New high-performance metals for 3D printing

3D Systems has added two new materials to its materials portfolio. Certified HX is a high-performance nickel alloy that contains a higher percentage of molybdenum (up to 9.5%) vs. other nickel alloys, which enhances strength and resistance to corrosion, creep deformation, cracking, and oxidation in hot-zone environments. Certified CuCr2.4 is a high-strength, corrosion-resistant copper alloy that is significantly stronger than pure copper and easier to process. Both materials are certified for use with the company's DMP Flex 350 and DMP Factory 350 3D printers.

Newly developed plastic film can kill viruses using room lights

Researchers at Queen's University Belfast in Ireland have developed a ground-breaking plastic film that can kill viruses that land on its surface when room light is shining.

The self-sterilizing film is the first of its kind: It is low cost to produce, can be readily scaled, and could be used for disposable aprons, tablecloths, and curtains in hospitals.

It is coated with a thin layer of particles that absorb UV light and produce reactive oxygen species (ROS). These unstable molecules contain oxygen and easily react with other molecules in a cell, killing viruses including SARS2.

The technology used to create the film also ensures it is degradable. Unlike the current disposable plastic films it would replace, this is a much more environmentally friendly materials option.

The breakthrough could lead to a significant reduction in the transmission of viruses in healthcare and other environments that use plastic films, such as food production factories.

The Queen's researchers tested the film for anti-viral activity using four different viruses -- two strains of influenza A virus, a highly stable picornavirus called EMCV, and SARS2 -- exposing it to either UVA radiation or with light from a cool, white-light fluorescent lamp.

They found the film is effective at killing all of the viruses -- even in a room lit with just white fluorescent tubes.

The research, which has been published in the Journal of Photochemistry and Photobiology B: Biology, was carried out by Professor Andrew Mills, Dr. Ri Han, and Dr. Christopher O'Rourke in the School of Chemistry and Chemical Engineering at Queen's University Belfast and Dr. Connor Bamford and Dr. Jonathon D. Coey at the Wellcome-Wolfson Institute for Experimental Medicine in the School of Medicine, Dentistry, and Biomedical Sciences at Queen's.

"This film could replace many of the disposable plastic films used in the healthcare industry, as it has the added value of being self-sterilizing at no real extra cost," said Mills. "Through rigorous testing, we have found that it is effective at killing viruses with just room light. This is the first time that anything like this has been developed, and we hope that it will be a huge benefit to society."
