Silicon Solves Problems for Next-gen LI Batteries

In the past it has been more expensive to produce batteries with silicon anodes instead of graphite. Some smart guys at the University of Eastern Finland have figured out how to do it a bit less expensive, which might allow for more dense lithium ion batteries. Tesla is currently using some silicon in anodes, but not at such a scale that would be allowed by this new process. While the article does not say much about it, it also mentions using silicon and carbon nanotubes, and also barley husk ash which is agricultural waste in future processes.



Researchers from the University of Eastern Finland introduced new technology to Li-ion batteries by replacing graphite used in anodes by silicon. The study analysed the suitability of electrochemically produced nanoporous silicon for Li-ion batteries. It is generally understood that in order for silicon to work in batteries, nanoparticles are required, and this brings its own challenges to the production, price and safety of the material. However, one of the main findings of the study was that particles sized between 10 and 20 micrometres and with the right porosity were in fact the most suitable ones to be used in batteries. The discovery is significant, as micrometre-sized particles are easier and safer to process than nanoparticles. This is also important from the viewpoint of battery material recyclability, among other things. The findings were published in Scientific Reports.

Large-Scale Dietary Study: Fats Good, Carbs Bad

An anonymous reader quotes CBS:
New research suggests that it’s not the fat in your diet that’s raising your risk of premature death, it’s too many carbohydrates — especially the refined, processed kinds of carbs — that may be the real killer… People with a high fat intake — about 35 percent of their daily diet — had a 23 percent lower risk of early death and 18 percent lower risk of stroke compared to people who ate less fat, said lead author Mahshid Dehghan. She’s an investigator with the Population Health Research Institute at McMaster University in Ontario… At the same time, high-carb diets — containing an average 77 percent carbohydrates — were associated with a 28 percent increased risk of death versus low-carb diets, Dehghan said…
For this study, Dehghan and her colleagues tracked the diet and health of more than 135,000 people, aged 35 to 70, from 18 countries around the world, to gain a global perspective on the health effects of diet. Participants provided detailed information on their social and economic status, lifestyle, medical history and current health. They also completed a questionnaire on their regular diet, which researchers used to calculate their average daily calories from fats, carbohydrates and proteins. The research team then tracked the participants’ health for about seven years on average, with follow-up visits at least every three years.

Here's What Phrases Like "Highly Likely" and "Probably Not" Mean to Different People

Just how likely does “probably” sound to you? Redditor zonination asked users of the polling subreddit /r/samplesize to assign percentage values to a range of common phrases about probability, and graphed the results. The sample size is tiny (just 46 respondents), but the data still looks clustered enough to be…

AMD Allegedly Loses $100 On Every Radeon RX Vega 64 GPU Sold
AMD’s Radeon RX Vega family of graphics is becoming known not only for its gaming performance, but also for how incredibly hard it is for enthusiasts to get their hands on them. The Radeon RX Vega 64 is supposed to have an MSRP of $499, but retailers have been tacking $100 to $200 on top of that price when they do have them in stock. Similar

Netflix develops Morse code search option

What happens when Netflix gives its staff two days to hack the platform and create innovative (and often unnecessary) variations on the streaming service?

This. This is what happens.

Hack Day Summer 2017 Teleflix

Uploaded by NetflixOpenSource on 2017-08-28.

Netflix Hack Day

Twice a year, the wonderful team at Netflix is given two days to go nuts and create fun, random builds, taking inspiration from Netflix and its content. So far they’ve debuted a downgraded version of the streaming platform played on an original Nintendo Entertainment System (NES), turned hit show Narcos into a video game, and utilised VR technology into many more builds that, while they’ll never be made public, have no doubt led to some lightbulb moments for the creative teams involved.

DarNES – Netflix Hack Day – Winter 2015

In a world… where devices proliferate… darNES digs back in time to provide Netflix access to the original Nintendo Entertainment System.

Kevin Spacey? More like ‘Kevin Spacebar’, am I right? Aha…ha…haaaa…I’ll get my coat.

Teleflix

The Teleflix build from this summer’s Hack Day is obviously the best one yet, as it uses a Raspberry Pi. By writing code that decodes the dots and dashes from an original 1920s telegraph (provided by AT&T, and lovingly restored by the team using ketchup!) into keystrokes, they’re able to search for their favourite shows via Morse code.

Netflix Morse Code

Morse code, for the unaware, is a method for transmitting letters and numbers via a standardised series of beeps, clicks, or flashes. Stuck in a sticky situation? Three dots followed by three dashes and a further three dots gives you ‘SOS’. Sorted. So long as there’s someone there to see or hear it, who also understands Morse Code.

Morse Code

Morse code was a method of transmiting textual information as a series of on-off tones that could be directly understood by a skilled listener. Mooo-Theme: http://soundcloud.com/mooojvm/mooo-theme

So if you’d like to watch, for example, The Unbreakable Kimmy Schmidt, you simply send: – …. . / ..- -. -… .-. . .- -.- .- -… .-.. . / -.- .. — — -.– / … -.-. …. — .. -.. – and you’re set. Easy!

To reach Netflix, the team used a Playstation 4. However, if you want to skip a tech step, you could stream Netflix directly to your Raspberry Pi by following this relatively new tutorial. Nobody at Pi Towers has tried it out yet, but if you have we’d be interested to see how you got on in the comments below.

And if you’d like to play around a little more with the Raspberry Pi and Morse code, you can pick up your own Morse code key, or build one using conductive components such as buttons or bananas, and try it out for yourself.

Alex’s Netflix-themed Morse code quiz

Just for fun, here are the titles of some of my favourite shows to watch on Netflix, translated into Morse code. Using the key below, why not take a break and challenge your mind to translate them back into English. Reward yourself +10 imaginary House Points for each correct answer.

  1. -.. — -.-. – — .-. / .– …. —
