Is the future of solid-state batteries 3D printed?
This may represent the future of rechargeable batteries. It offers enhanced power, improved safety, quicker charging times, and an extended lifespan. Theoretically, it could also be designed in any shape desired. Private enterprises and research institutions are competing to develop a battery that could eventually replace the ubiquitous lithium-ion variety. One company is pushing the boundaries further by exploring the concept of 3D printing batteries, thereby transforming our perception of their appearance. To understand the fundamentals, let us define what a battery is. A standard battery operates by converting chemical energy into electrical energy. It requires a positive terminal, known as the cathode, exemplified here by a zinc-coated nail, and a negative terminal, or anode, represented by a copper penny. Additionally, an electrolyte is necessary to connect these two components, which in this demonstration is provided by a potato. I will place one here and another here. The chemical reaction between each terminal and the potato facilitates the release of electrons from the anode, which then travel through the wire back to the cathode. This movement of electrons is what transforms the chemical reaction into electrical energy. Although the initial setup did not yield any results, adding a few more potatoes should enable the light to function. Thank you. These clips are quite challenging. Now, if we could have the lights, please. That was quite effective. This illustrates the basic principle behind any chemical battery. Lithium-ion batteries are among the most successful iterations of this technology. However, there is potential for enhancement, and startups are focusing on two critical aspects of the design: the electrolyte and the anode. Currently, nearly all commercially available batteries utilize a liquid electrolyte. We refer to them as lithium-ion batteries because the electrolyte is saturated with lithium ions that facilitate charge movement. While liquid electrolytes are excellent conductors, they are also volatile, especially when compromised or exposed to high temperatures. If you have been following the news, you may have encountered reports of incidents such as this.

Oxygen level in water resources is rapidly decreasing ☠️
What's going on? Climate change issues: So, with weather change heating things up, the water cannot hold as lots oxygen. Warm water just doesn’t blend as nicely, which means the oxygen from the surface isn't setting out to the depths in which it’s wanted. Over the beyond 50 years, the oxygen tiers in the oceans have dropped via about 2%

NASA Just Dropped a New Image of an Alien Planet Only 12 Light-Years Away!
A First for the James Webb Space Telescope This is super exciting because it’s the first time the JWST has imaged an exoplanet that hadn’t already been spotted with ground-based telescopes. Exoplanets, in case you didn’t know, are planets that orbit stars other than our sun. Almost all of the 5,000 known exoplanets have been found indirectly using the transit method, which detects changes in a star’s light as a planet crosses in front of it. But fewer than 25 exoplanets have been directly imaged, which means we actually see them as a bright dot near their star. How cool is that?

To all my fellow creators
Why do you share your work and journey with your social network? Nobody cares about what you do in your life. ⏩This! How often do we come across this statement? The argument for instant gratification that we gain while sharing glimpses or content about our journeys being detrimental for us, in the long run, is completely valid. The validation that we crave from external realms often stems from a lower sense of self-esteem.

New Invention !: Generating Electricity from Thin Air
How does it work? The Air-gen tool is fabricated from protein nanowire films produced via microorganisms. These nanowires are sandwiched between the electrodes, and the nanowire film absorbs moisture from the air. As water molecules are absorbed, they devise an energy imbalance and generate electricity. The procedure transforms the encompassing water right into a small but efficient move, capable of powering electronics and providing a reliable strength source in locations where solar and wind electricity might not nicely
