#Ions - They make beautiful colours in the sky ✨, but what do they do when we get them 'stuck' in a plastic film ⁉️

with @andrissutka.bsky.social in @apsphysics.bsky.social #PRL we show the film transforms into an electrically responsive⚡surface!

Proud to announce our recent work in prestigious PHYSICAL REVIEW LETTERS (10.1103/th79-cjz6). The ion-implanted polymers possess space charge that can be exploited to deliver materials for sensors and energy harvesting. A collaboration I built during the project TriboCharge. @nanoin3d.bsky.social

Impact of Initial Charge Conditions on the Slide Electrification of Droplets Contact electrification and electrostatic induction are the core mechanisms behind solid–liquid (SL) triboelectric nanogenerators (TENGs), which have garnered interest for powering microscale devices....

What if Solar Panels harvested energy when rain was falling ❔

In @acs.org #Langmuir - we looked at raindrops falling and sliding. We show the ⚡ charge already on a surface before a droplet 💧 hits a surface matters... a lot⁉️

Polymer beads generate electricity for self-charging devices using simple friction An international team has discovered a simple and environmentally friendly way to power the next generation of self-charging electronics.

Microscopic polymer spheres can generate electricity through friction, enabling thin, eco-friendly films that harvest energy for self-charging devices without toxic materials or complex manufacturing. doi.org/hbcxqj

We lack the budget to fund all the project proposals that are assessed as excellent by our peer review panels.

So it's encouraging to see that some of these projects eventually receive funding.

A big thank you to the Latvian government for supporting excellent science; a worthwhile investment!

In the project TriboCharge, “Controlling and exploiting triboelectric effect in polymers for mechanical-to-electrical-chemical conversion,” I will study the origin of static charge, how to introduce this charge in the volume of multilayered materials, and how to exploit it in chemical synthesis.

My @ERC.europa.eu journey has ended with a positive outcome. After receiving an “A” score after the interview, full funding was granted from the European Regional Development Fund Latvia @CFLA_gov_lv. Thanks to everyone involved, especially my colleagues at Alma Mater @RTU_LV.

Printing Bioderived and Biodegradable Triboelectric Nanogenerators via Dual-Head Additive Manufacturing Society needs regenerative technology, that is, technology that replenishes the world as it functions. While energy harvesting technology, including triboelectric nanogenerators (TENGs), provide promi...

New research out in @acs.org Sus. Chem. & Eng.

#Bioderived #polymers (from plant extracts) are #3Dprinted and work better - than petroleum-based polymers for Mechanical-to-Electrical conversion #TENGs
