Title: Material Science and Tech and Wild Speculation
Post by: brilligtove on December 05, 2015, 09:16:00 AM
I find the science and technology of new material fascinating. Graphene and nanoscale electrodes and metamaterials and tuneable coloured glass and... Well, I think it's all pretty cool, and love imagining what could be cone with this new stuff. If you find it interesting too, post links to new materials and new uses of them, and we can all speculate wildly.

Today, I've seen two fun articles:

Penn Researchers Make Thinnest Plates That Can Be Picked Up by Hand (http://www.upenn.edu/pennnews/news/penn-researchers-make-thinnest-plates-can-be-picked-hand)
Quote
Researchers at the University of Pennsylvania have now created the thinnest plates that can be picked up and manipulated by hand. Despite being thousands of times thinner than a sheet of paper and hundreds of times thinner than household cling wrap or aluminum foil, their corrugated plates of aluminum oxide spring back to their original shape after being bent and twisted.

I wonder if a composite with graphene would be possible, giving a super thin, untearable, flexible material.

Nanoscale drawbridges open path to color displays (http://news.rice.edu/2015/12/04/nanoscale-drawbridges-open-path-to-color-displays-2/)
Quote
Rice develops first method for reversible color changes with metal nanoparticles. A new method for building “drawbridges” between metal nanoparticles may allow electronics makers to build full-color displays using light-scattering nanoparticles that are similar to the gold materials that medieval artisans used to create red stained-glass.

I would love to see the gorilla glass be the display surface one day, with the battery and electronics in a thin bezel around the edge of a phone.

Here's one about making more effective use of existing batteries.

Electric Cars: Batteries with brains (http://www.sciencedaily.com/releases/2015/12/151204094510.html)

Date: December 4, 2015
Source: Fraunhofer-Gesellschaft (https://www.fraunhofer.de/en/press/research-news/2015/december/electric-cars-batteries-with-brains.html)
Key Concepts: Existing batteries in cars are expensive for a few reasons. One is that all the individual cells have to have essentially the same capacity. This is because the cells are connected in series, so if one drains early the entire battery is dead, no matter how much power is still available in the rest of the cells. The new smart cells know when they are tapped out and bridge neighbouring cells together - removing a performance barrier. This reduces costs by eliminating the need to sort through and match cell capacities, and results in a small but significant boost in overall available power in a battery. these cells can also be designed to be replaceable, so when they fall below a performance threshold the whole battery can be reconditioned by removing and replacing only the cells that are in the worst condition.

Transparent metal films for smart phone, tablet and TV displays (http://www.sciencedaily.com/releases/2015/12/151214142549.htm)
A new material that is both highly transparent and electrically conductive could make large screen displays, smart windows and even touch screens and solar cells more affordable and efficient, according to materials scientists and engineers at Penn State who have discovered just such a material.

New ceramic firefighting foam becomes stronger when temperature increases (http://www.sciencedaily.com/releases/2015/12/151214134550.htm)
A team of chemists from ITMO University, in collaboration with research company SOPOT, has developed a novel type of firefighting foam based on inorganic silica nanoparticles. The new foam beats existing analogues in fire extinguishing capacity, thermal and mechanical stability and biocompatibility. The results of the study were published in ACS Advanced Materials & Interfaces

Tooth fillings of the future may incorporate bioactive glass (http://oregonstate.edu/ua/ncs/archives/2015/dec/tooth-fillings-future-may-incorporate-bioactive-glass)
Quote
12/22/2015

CORVALLIS, Ore. – A few years from now millions of people around the world might be walking around with an unusual kind of glass in their mouth, and using it every time they eat.

Engineers at Oregon State University have made some promising findings about the ability of “bioactive” glass to help reduce the ability of bacteria to attack composite tooth fillings – and perhaps even provide some of the minerals needed to replace those lost to tooth decay.

[snip]

If this laboratory result is confirmed by clinical research, it should be very easy to incorporate bioactive glass into existing formulations for composite tooth fillings, Kruzic said.

Self-indulgence regularly revolutionizes our lives.  For instance, the strength of the porn industry is one of the things that helped VHS topple Betamax.  Wanting to keep your food cold evolved design of the refrigerator.  Self-indulgence in television changed and evolved how we acquire news and information (Fox News notwithstanding). 

What necessity doesn't invent, laziness and self-indulgence does.

If you haven’t already heard of antiferromagnetic spintronics it won’t be long before you do. This relatively unused class of magnetic materials could be about to transform our digital lives. They have the potential to make our devices smaller, faster, more robust and increase their energy efficiency.

Spintronics have been around for a long time. I think I first read bout them in Scientific American two decades ago. This may be a step to practical devices.

Quote
Liquid crystal elastomers (LCEs), essentially rubbers with liquid crystal properties, can do a number of fascinating things, especially in the fields of optics, photonics, telecommunications and medicine. They can curl up, bend, twist, wrinkle and stretch when exposed to light, heat, gases and other stimuli. Because they are so responsive, they are ideal for applications like artificial muscles and blood vessels, actuators, sensors, plastic motors and drug delivery systems. They can even be used as a mechanically tunable mirrorless “rubber” laser.

New lens ready for its close-up
http://www.eurekalert.org/pub_releases/2016-02/uou-nlr021116.php
Quote
Imagine digital cameras or smartphones without the bulky lenses or eyeglasses with lenses that are paper thin.

Researchers have always thought that flat, ultrathin optical lenses for cameras or other devices were impossible because of the way all the colors of light must bend through them. Consequently, photographers have had to put up with more cumbersome and heavier curved lenses. But University of Utah electrical and computer engineering professor Rajesh Menon and his team have developed a new method of creating optics that are flat and thin yet can still perform the function of bending light to a single point, the basic step in producing an image.

Graphene, a modified form of carbon, offers versatile potential for use in coating machine components and in the field of electronic switches. An international team of researchers led by physicists at the University of Basel have been studying the lubricity of this material on the nanometer scale. Since it produces almost no friction at all, it could drastically reduce energy loss in machines when used as a coating, as the researchers report in the journal Science.

I want one of these mirrors.

I am reminded of a study where the subjects were shown several snaps of themselves in quick succession, taken by the researchers, and asked to pick their favorite.  Unbeknown to the subject, one of the photos had been mirror-imaged. To a very high correlation, this was the "best" shot taken.

The mirror image is the person we "know" and everyone else knows us as a different person.

I have this huge queue of articles to post here and decided to just etch-a-sketch it and start fresh.

This is really cool: https://www.wired.com/2016/06/tiny-engine-one-step-closer-powering-drones-electric-cars/

I always loved the Wankel Rotary engine. When I was 15 I came up with the idea of a rotary engine independently, while messing around with geometric shapes. I didn't think it the whole way through - just enough to be convinced it could work, and that it would need something to get it spinning before the engine would work. Years later I connected the dots to the Monty Pyhon skit about words that sound dirty but aren't and did some library digging. It was nice to know I was on the right track. This engine looks like it could have some really effective uses, especially if it can be run on carbon neutral fuels.

Hm. It think this fits this old thread: Discovery of a bottleneck relief in photosynthesis may have a major impact on food crops (https://www.eurekalert.org/pub_releases/2019-08/acoe-doa081419.php).

I imagine with hundreds of millions of years to work with, gaining 10% growth through over-expression of a single protein would be a relatively likely mutation. This makes me think there will likely be a fairly catastrophic impact on reproductive fitness that shows up as research continues. Even if that's the case and the plants with the edit can't reproduce in the wild I can see massive business potential for something like farmed wood instead of clear-cutting.
