New titanium alloy has highest specific strength of any 3D-printed metal

Engineers have developed a new 3D-printed titanium alloy with a unique microstructure that makes it ultra-strong. Not only is it stronger than other forms of titanium, but it has the highest strength-to-weight ratio of any 3D-printed metal ever made.

New polymer removes dye from wastewater, and can be reused afterwards

In wastewater produced by the textile industry and others, dye is one of the primary pollutants. A newly developed synthetic polymer is capable of removing that dye from the water, plus it can be cleaned up and reused to treat more wastewater.

Powerful new adhesive stays strong from freezing to boiling temperatures

A powerful new adhesive can grip strongly in extreme temperatures, from the deep freeze of liquid nitrogen to the sweltering heat of an oven. Better yet, it can be broken back down into its component parts and reused without losing strength.

Plant-based plastic strong as PET, degrades into sugars in the environment

Plastics are tough, which is great when in use but not so good in the environment. Scientists have developed a new PET-like plastic derived from waste plant matter that can be chemically recycled or degrade into harmless sugars in the environment.

Lab-grown plant matter marks a step towards 3D-printable wood

Processing wood from trees isn’t the most efficient way to make furniture or building materials. MIT scientists have made breakthroughs in a process that could one day let us 3D print and grow wood directly in the shape of furniture and other things.

Teflon-like desalination membrane purifies water fast and friction-free

A new type of desalination membrane uses a series of nanoscale tubes lined with a Teflon-inspired material that repels salts while allowing water to flow through with little friction. The team says it's fast, and requires little pressure and energy.
