NanoJunkie: Recent Episodes
Ari Esters
I'm obsessed with microtechnology and nanotechnology and the impact it will have on our society. In fact, this impact is not too far away. Many companies and research groups are already developing products in the “micro-nano” space, and investors are becoming more and more interested. To understand this developing field, I will research different companies, particularly startups, that are working to impact or disrupt the industries of renewable energy, medicine, biotech, sustainability, manufacturing, space exploration, and more.

I've been seeing a lot of news and talk about the semiconductor "chip shortage" that's been going on since last year. Here, I explain what the chip shortage is, what caused it, and how it will change the future of US manufacturing.

What’s the big deal with nanotech? Where is it used? Is it worth investing in nanotech at all?
All that and more covered in this episode!

I’m power-walking on a windy day, so pardon the audio quality. In this episode, I share the plan I’ve put into motion for NanoJunkie: a new website (nanojunkie.com), weekly blogs, and interviews with companies and researchers, to name a few.

After a year and a half of silence, I'm finally continuing the NanoJunkie platform.

05-11-2019: NanoJunkie episodes will be paused until I get a new laptop. May take a few weeks or even a couple months..

In Episode 7 of Nanotech News, I talk about recent developments in efficient light-based circuits for use in quantum technology, spiral nanobots that improve drug delivery in the body, and flexible circuits made using 3D printing and nanotechnology.

04-27-2019: I finally got a new microphone for audio recording, which seems to work pretty well! Listen to this silky smooth audio which entails me recalling how busy work has gotten in just a week, complaining about how much time I've spent on Netflix, and failing to remember when the movie Hurt Locker came out (it was 2008).
New nanotech episodes coming soon! Enjoy!
I apologize in advance for this audio. I was in a noise-heavy room, so the end result after editing sounds kinda distorted. This episode of Nanotech News includes three recent developments: (1) moving and levitating objects with light, (2) fusing technology with microbial life to clean up the planet, and (3) discovering 2D materials using artificial intelligence.

What if humans had the same camouflage ability as chameleons? Can we make suits that can shift colors and patterns and allow humans to blend in with any surface? How can we build materials that controllably change color in real time? Actually, I believe that all of these are possible...not with future technology, but with our current technology.

Will we ever be technologically advanced enough to build Tony Stark's nanotechnology suit from Avengers: Infinity War? Or to make clothing and surfaces that change color like a chameleon? Or to have self-assembling furniture composed of microrobots? These are the types of questions I LOVE to discuss. Very soon, I will make episodes centered around these topics and more!

04-12-2019: Recording from my car after work. I recorded this audio from my phone while on the go, so the audio quality is worse than usual. Nevertheless, I wanted to make sure I checked in, and I briefly talk about my ideas for the future of NanoJunkie.

I finally got to record an episode about nanobots, which is a HOT topic in nanotechnology. Many news outlets have covered nanobots in recent years, particularly because of their potential to target and destroy tumors in the body. But...what exactly is a nanobot? How can we make a nanobot kill cancer cells? We should probably learn more about them before we stick them in our bloodstream. That's what this episode is for!

In this episode of Nanotech News, I cover a bit about batteries and the potential for better energy storage devices using two-dimensional (2D) materials. I'm still kinda sad that I didn't get to take any electrochemistry or battery-related courses while I was in school, so this episode is probably a good way for me to scratch that itch.

I have not forgotten about this podcast! In fact, I have a quick announcement: the next Nanotech News episode will be coming out within a couple days! In this episode, I will discuss the potential for the next generation of battery technology based on two-dimensional materials.

Keep your ears open!
In this episode of Nanotech News, I will be discussing a new paper that may lead to a new form of data storage by controlled phase transitions in atoms or groups of atoms. There are many new and innovative ways of storing bits of informations, but storing data in individual atoms could offer the densest form of data storage to date.
(I apologize in advance for some of the bad audio quality in this one. I'm still experimenting to find the optimal recording setup.)

In this installment of the nanotech series, I discuss a new development that I've been hearing a lot about recently in nanotech circles: holey graphene. Why would you want to purposefully make holes in graphene? Doesn't that lower its quality and effectiveness? What's the deal? It turns out graphene in holes can be really useful as well, as I discuss here!

02-15-2019: Today, I’m covering an article about a graphene-based innovation developed by researchers at the University of Manchester. This new nanotechnology has the potential to turn plain old ocean water into freshwater, providing potential solutions to water security and sustainability worldwide.
