A new 'gold standard' for safer ceramic coatings

Making your own ceramics can be a way to express your creativity, but some techniques and materials used in the process could spell bad news for your health and the environment. If not prepared properly, some glazed ceramics ...

Pesticide seed coatings are widespread but underreported

Pesticide-coated seeds—such as neonicotinoids, many of which are highly toxic to both pest and beneficial insects—are increasingly used in the major field crops, but are underreported, in part, because farmers often do ...

An environmentally friendly alternative to toxic ship coatings

High-powered, ultra-fast lasers are increasingly used in industrial applications, thanks to their ability to remove material of almost any kind. With smooth, melt-free cuts, even on a micron scale, ultra-fast lasers are particularly ...

Bacteria killed by new light-activated coating

To stop the spread of disease, it could be used to coat phone screens and keyboards, as well as the inside of catheters and breathing tubes, which are a major source of healthcare-associated infections (HCAIs).

A new template for nonspherical viral nanocages

In nature, viruses use nanocages to protect their genome. Some of these viruses can be disassembled into protein units to remove their genome. These protein units can then be reassembled into nanocages by other templates, ...

Nanolaminate-based design for UV laser mirror coating

The demand for laser-resistant mirror coatings is increasing in inertial confinement fusion, extreme light infrastructure and other laser applications. The ideal UV laser mirror (UVLM) coating requires high reflectivity with ...

Coating

Coating is a covering that is applied to an object. The aim of applying coatings is to improve surface properties of a bulk material usually referred to as a substrate. One can improve amongst others appearance, adhesion, wetability, corrosion resistance, wear resistance, scratch resistance, etc.. They may be applied as liquids, gases or solids. Coatings can be measured and tested for proper opacity and film thickness by using a Drawdown card.
