New transparent metadevices based on quasi-1D surface plasmon polariton structures

Posted by in categories: solar power, sustainability, wearables

Transparent electronic devices could have numerous valuable real-world applications. Among other things, they could enable the creation of new optical devices, smart gear or wearables, invisible solar panels and integrated communication systems.

Researchers at Xidian University, Southeast University and Wuhan University of Technology recently developed new, highly promising, transparent metadevices based on quasi-one-dimensional surface plasmon polariton (quasi-1D SPP) structures. These devices, introduced in a paper published in Nature Electronics, could be used to develop optically and radiofrequency transparent wireless and other .

“Transparent and invisible electronic is a fascinating goal that scientists and engineers are enthusiastically pursuing,” Prof. Bian Wu, one of the researchers who carried out the study, told Tech Xplore. “Currently, typically rely on the intrinsic properties of optically conductive materials, which are not radiofrequency transparent and have low operating efficiency. SSPs can be used to concentrate, channel and enhance energy. However, the use of SPPs in the development of optical and radiofrequency transparency remains blank.”

Low-cost additive turns concrete slabs into super-fast energy storage

Posted by in categories: energy, sustainability, transportation

MIT researchers have discovered that when you mix cement and carbon black with water, the resulting concrete self-assembles into an energy-storing supercapacitor that can put out enough juice to power a home or fast-charge electric cars.

We’ve written before about the idea of using concrete for energy storage – back in 2021, a team from the Chalmers University of Technology showed how useful amounts of electrical energy could be stored in concrete poured around carbon fiber mesh electrodes, with mixed-in carbon fibers to add conductivity.

MIT’s discovery appears to take things to the next level, since it does away with the need to lay mesh electrodes into the concrete, and instead allows the carbon black to form its own connected electrode structures as part of the curing process.

Engineers create an energy-storing supercapacitor from ancient materials

Posted by in categories: energy, sustainability, transportation

Two of humanity’s most ubiquitous historical materials, cement and carbon black (which resembles very fine charcoal), may form the basis for a novel, low-cost energy storage system, according to a new study. The technology could facilitate the use of renewable energy sources such as solar, wind, and tidal power by allowing energy networks to remain stable despite fluctuations in renewable energy supply.

The two materials, the researchers found, can be combined with water to make a supercapacitor—an alternative to batteries—that could provide storage of electrical .

As an example, the MIT researchers who developed the system say that their supercapacitor could eventually be incorporated into the concrete foundation of a house, where it could store a full day’s worth of energy while adding little (or no) to the cost of the foundation and still providing the needed structural strength. The researchers also envision a concrete roadway that could provide contactless recharging for as they travel over that road.

Ultrafast Internet At Home Could One Day Be Delivered Via LED Lightbulbs

Posted by in categories: internet, particle physics, solar power, sustainability

Perovskite-based light emitting diodes (LEDs) could be the key to developing internet bandwidths orders of magnitude faster than what is now available, while also keeping energy consumption and cost down, researchers have claimed. Other potential applications lie in laser technology.

Perovskite is a natural mineral first identified in Russia’s Ural Mountains in 1,839 and composed primarily of calcium, titanium, and oxygen – all in the 10 most common elements in the Earth’s crust. The mineral gave its name to a class of materials based on the same elements but doped with small quantities of others. For almost the first two centuries after their discovery, these perovskites were largely a curiosity of interest only to chemists.

More recently, however, the ability of perovskites to display different electrical properties depending on the atoms with which they are doped has turned them into a wonder material. Perovskites now represent one of the most efficient ways to trap energy from sunlight and are continuing to improve at unprecedented rates. Moreover, perovskites have the potential to be manufactured far more cheaply than traditional silicon-based solar cells, while a layer of perovskite over a silicon base could capture more light than either on their own.

Complex brain cell connections in the cerebellum more common than believed

Posted by in categories: neuroscience, sustainability

The STAR party’s vision for Canada includes the research and development of self sustainable Mobile Airborne Cities; or Airborne Arcologies. Being an obviously semi-long term goal, the objective would be to at first, allocate budgeting towards research and development of components to build this project in a phased manner… and the scaling of the project as technology allows for it.

Phase I: research and development of scalable micro-prototypes.

Phase II: multiple prototype development / testing stages.

Rumors are swirling about a new Tesla battery that could give its cars 100 miles of charge in just 5 minutes

Posted by in categories: sustainability, transportation

Electric vehicle manufacturer Tesla is the frequent subject of rumors and speculation, all of which must be taken with a grain of salt. But if the newest batch of rumors is to be believed, Tesla is currently looking into an “extreme fast charging” technology developed by Israeli startup StoreDot, per Inside EVs.

The news comes via an article in USA Today that, as Inside EVs noted, “doesn’t cite any sources.” The USA Today article in question was written by a contributor and contained a disclaimer at the bottom reading, “Members of the editorial and news staff of the USA TODAY Network were not involved in the creation of this content.”

If the report is to be believed, Tesla’s interest in StoreDot could mean shorter charging times for Teslas, as the company claims to have developed batteries that can charge 100 miles of driving range in just five minutes, per Inside EVs.

News About Advances in Sodium-Ion and Solid-State Batteries

Posted by in categories: economics, energy, sustainability, transportation

Sodium-ion (Na-ion) batteries and solid-state batteries have both been in the news recently. Why? Because the need for battery storage is growing rapidly as the global economy seeks carbon-based energy alternatives in pursuit of the goal to achieve net-zero emissions by the mid-century.

Na-ion Battery News

In April I wrote about BYD, a Chinese electric vehicle (EV) manufacturer, that is using sodium-ion (Na-ion) battery packs instead of lithium-ion (Li-ion) in some of its models. In its latest report, IDTechEx, out of Cambridge in the United Kingdom, states that although Na-ion batteries are not the answer to all battery-power applications, they do provide a complimentary addition to battery packs used not just in EVs but also for backup power within utilities and factories.

Artificial photosynthesis with engineering of protein crystals in bacteria

Posted by in categories: engineering, genetics, solar power, sustainability

In-cell engineering can be a powerful tool for synthesizing functional protein crystals with promising catalytic properties, show researchers at Tokyo Tech. Using genetically modified bacteria as an environmentally friendly synthesis platform, the researchers produced hybrid solid catalysts for artificial photosynthesis. These catalysts exhibit high activity, stability, and durability, highlighting the potential of the proposed innovative approach.

Protein crystals, like regular crystals, are well-ordered molecular structures with diverse properties and a huge potential for customization. They can assemble naturally from materials found within cells, which not only greatly reduces the synthesis costs but also lessens their environmental impact.

Although are promising as catalysts because they can host various functional molecules, current techniques only enable the attachment of small molecules and simple proteins. Thus, it is imperative to find ways to produce protein crystals bearing both natural enzymes and synthetic functional molecules to tap their full potential for enzyme immobilization.
