What new materials are there?

"Molecular programming"? Dude must be a marketer in his day job. Saw this vid a few days ago. Damascus steel, nothing more.

Battery breakthrough using 2016 Nobel Prize molecule

Silicon anodes are receiving a great deal of attention from the battery community. They can deliver around three to five times higher capacity compared with those using current graphite anodes in lithium ion batteries. A higher capacity means longer battery use per charge, which is particularly...

Bioglass isn't exactly a new material, but it's still interesting.

Just don't take up boxing for a career as it will add new meaning to the term "having a glass jaw".

New nanomaterial can extract hydrogen fuel from seawater

It's possible to produce hydrogen to power fuel cells by extracting the gas from seawater, but the electricity required to do it makes the process costly. UCF researcher Yang Yang has come up with a new hybrid nanomaterial that harnesses solar energy and uses it to generate hydrogen from...

Scientists mix the unmixable to create 'shocking' nanoparticles

Making a giant leap in the 'tiny' field of nanoscience, a multi-institutional team of researchers is the first to create nanoscale particles composed of up to eight distinct elements generally known to be immiscible, or incapable of being mixed or blended together. The blending of multiple, unmixable elements into a unified, homogenous nanostructure, called a high entropy alloy nanoparticle, greatly expands the landscape of nanomaterials—and what we can do with them.

This research makes a significant advance on previous efforts that have typically produced nanoparticles limited to only three different elements and to structures that do not mix evenly. Essentially, it is extremely difficult to squeeze and blend different elements into individual particles at the nanoscale. The team, which includes lead researchers at University of Maryland, College Park (UMD)'s A. James Clark School of Engineering, published a peer-reviewed paper based on the research featured on the March 30 cover of Science.

Maybe a new super energetic material could be made?

Composite metal foams provide armor protection for one third the weight and make super car bumpers | NextBigFuture.com

Stainless steel composite metal foam can replace rolled homogeneous steel armor with the same protection for one-third of the weight.

Stainless steel composite metal foam can replace rolled homogeneous steel armor with the same protection for one-third of the weight.

According to the material’s inventor the material would make a great bumper, as the sponginess of the metal foam soaks up impact energy. Raibei claims that for a passenger sitting in a car outfitted with a composite metal foam bumper, a collision at 28 miles an hour will feel like a 5 mile per hour collision. This gives a hint as to how effective it is in soaking up the energy of a rifle bullet—or even a tank round.

Composite metal foam can block fragments but also the blast waves that are responsible for trauma such as major brain injuries. That would reduce vehicle weight significantly, improving fuel mileage and vehicle performance.

I did not see this so.... CNRP (Carbon Nanotube Reinforced Polymer)

AZCsTaP.png


https://www.flightglobal.com/news/articles/lockheed-martin-reveals-f-35-to-feature-nanocomposite-structures-357223/

Non load-bearing parts for the F-35 are already being made with CNRP and for much cheaper than CFRP (Carbon Fiber Reinforced Polymer).

Lockheed, however, has invented a process that dramatically reduces the cost to build carbon nanotube composites for aircraft structures, Earles said. The new wingtip fairing is being made for one-tenth of the cost of the equivalent CFRP component, he said.

Now imagine if they could make large, load-bearing structures from CNRP... say bye-bye to Titanium bulkheads and the time, cost, and dependence on foreign Ti sources.
 
Are those figures from the article linked? I couldn’t see them in the non-subscriber view.

It’s a pretty impressive strength figure, though probably tensile strength. Compressive strength, vital for load-bearing, might be quite different.
 
If only it was that easy.

CNT’s have a very neutral surface charge hence finding a composite matrix material which will stick to them is proving difficult. This means when a CNT composite is loaded the tubes tend to slip in the matrix which leads early failure of the rather brittle CNT.

Boron Nitride Nano Tubes (BNNT) are just as strong, have a higher temperature capability, have much higher surface charge and are galvanically nicely matched to Aluminium....... which sticks very well. My bet is you’ll see this first.

Ps Lockheed’a Steel and Ti are pretty poor, the ultra high tensile steels I’m familiar with have a UTS of 1800MPa and Ti allloys at 1500Mpa. My guess is these were selected for dramatic effect.

Scientists create innovative new ‘green’ concrete using graphene

A new greener, stronger and more durable concrete that is made using the wonder-material graphene could revolutionise the construction industry.

Experts from the University of Exeter have developed a pioneering new technique that uses nanoengineering technology to incorporate graphene into traditional concrete production.

The new composite material, which is more than twice as strong and four times more water resistant than existing concretes, can be used directly by the construction industry on building sites. All of the concrete samples tested are according to British and European standards for construction.

Pretty sure graphene is going to be WAYYYY more expensive than rebar, sand, gravel, and rocks. :eek:
