A QUT-led team of international researchers has made a breakthrough in the development of a type of battery that is much safer and cheaper than the batteries currently charging our smart devices.

The research, published in the prestigious Journal of the American Chemical Society, has demonstrated a way of improving the voltage of aqueous zinc-ion batteries, which are a type of rechargeable battery which have a water-based electrolyte.

QUT researchers involved in the study are Professor Ziqi Sun, Associate Professor Dongchen Qi, and Fan Zhang from the School of Chemistry and Physics, Professor Ting Liao and Professor Cheng Yan from the School of Mechanical, Medical and Process Engineering and Dr Aaron Micallef from the Central Analytical Research Facility.

Nuclear energy has long been regarded as a next-generation energy source, and major countries around the world are competing to secure cutting-edge technologies by leveraging the high economic efficiency and sustainability of nuclear power. However, uranium, which is essential for nuclear power generation, has serious implications for both soil ecosystems and human health.

Despite being a key radioactive material, uranium poses significant health risks due to its chemical toxicity to the kidneys, bones, and cells. As a result, both the U.S. Environmental Protection Agency and the World Health Organization recommend allowing and advocating for uranium concentrations in wastewater to be below 30 μg/L.

The Korea Institute of Civil Engineering and Building Technology (KICT) has conducted research on a nano-material-based adsorption process to efficiently remove uranium wastewater extracted from actual radioactive-contaminated soil. They have also proposed its applicability to prevent secondary environmental pollutions.

Engineered protein filaments originally produced by bacteria have been modified by scientists to conduct electricity. In a study published recently in the journal Small, researchers revealed that protein nanowires—which were modified by adding a single compound—can conduct electricity over short distances and harness energy from moisture in the air.

“Our findings open up possibilities for developing sustainable and environmentally friendly electrical components and devices, based on proteins,” says Dr. Lorenzo Travaglini, lead author on the paper. “These engineered nanowires could one day lead to innovations in energy harvesting, biomedical applications and environmental sensing.”

Developments in the interdisciplinary field that combine protein engineering and nanoelectronics also hold promise for developing cutting-edge technologies that bridge the gap between biological systems and electronic devices.

So we can now entertain idea of overseeing our solar system by placing a network of comm satelites…live orbital feeds from at least our neerest solar objects.

Laser beam comms are fast, so long as the weather cooperates.

Through years of engineering gene-editing systems, researchers have developed a suite of tools that enable the modification of genomes in living cells, akin to “genome surgery.” These tools, including ones based on a natural system known as CRISPR/Cas9, offer enormous potential for addressing unmet clinical needs, underscored by the recent FDA approval of the first CRISPR/Cas9-based therapy.

A relatively new approach called “prime editing” enables gene-editing with exceptional accuracy and high versatility, but has a critical tradeoff: variable and often low efficiency of edit installation. In other words, while prime edits can be made with high precision and few unwanted byproducts, the approach also often fails to make those edits at reasonable frequencies.

In a paper that appeared in print in the journal Nature on April 18, 2024, Princeton scientists Jun Yan and Britt Adamson, along with several colleagues, describe a more efficient prime editor.

Dielectric capacitors are ubiquitous components that play a vital role in electronic devices and energy storage systems. Their ability to rapidly discharge significant amounts of energy makes them indispensable for high-power applications.

“High-energy and high-power capacitors are the backbone of reliable power supplies, especially as we transition towards renewable energy sources,” explains Alamgir Karim, Dow Chair and Welch Foundation Professor of Chemical Engineering at UH and a faculty mentor on the project. “However, current dielectric capacitors fall short in terms of energy storage capacity compared to other options like batteries. The advantage of capacitors lies in their superior power density, making them a more suitable choice for various applications.”

The key factor influencing a capacitor’s energy storage is a combination of its permittivity (ε) and dielectric breakdown strength (EBD). Professor Karim emphasizes, “To enhance a capacitor’s energy storage, advancements in both these aspects are crucial.”

Instead of creating materials that are made to last, Freeman says their materials are made to task — perform a specific function and then modify themselves to serve a new function.

This achievement holds significant promise for advancements in regenerative medicine, drug delivery methods, and diagnostic technologies.

“With this discovery, we can think of engineering fabrics or tissues that can be sensitive to changes in their environment and behave in dynamic ways,” states Freeman.

In order to terraform new planets, we will need to be able transport entire ecologies & ecosystems through interstellar space in the future. Today we will examine how we could build and maintain such environments inside vast arks, generations ships able to colonize our galaxy, and the challenges these starships will face maintaining not just stores of DNA and genetic material but living organisms which depend heavily on other members of their species and other species to survive and thrive, not least of which is human ourselves.
