Neutral Zinc-air battery with cathode NiCo/C-N shows outstanding performance

Posted by in categories: bioengineering, energy, sustainability

In a paper to be published in the forthcoming issue in NANO, a team of researchers from the School of Chemistry and Chemical Engineering at Hunan University of Science and Technology have proposed a novel strategy for the synthesis of non-precious metal catalysts in zinc-air batteries that do not compromise its electroactivity, affordability and stability.

As a green and sustainable energy generator, zinc-air battery has attracted great attention from researchers due to its high specific energy, high current density, low cost, and environmental friendliness. Yet it is not without its drawbacks. The slow oxygen reduction reaction (ORR) of its cathode has become an obstacle to its commercial application. One possible solution is to use platinum (Pt) and Pt-based catalysts, but its high cost and scarce availability make it less ideal. In addition, alkaline KOH (or NaOH) is generally used as the electrolyte, but it leads to the generation of carbonates (CO32-) due to the dissolution of CO2 in the electrolyte as well as the spontaneous corrosion of the anodic zinc in strong alkaline media. This has the effect of slowing down the ionic conductivity of the electrolyte and battery life. Therefore, a neutral electrolyte should be used instead.

From medicine to nanotechnology: How gold quietly shapes our world

Posted by in categories: biotech/medical, chemistry, nanotechnology

The periodic table of chemical elements turns 150 this year. The anniversary is a chance to shine a light on particular elements – some of which seem ubiquitous but which ordinary people beyond the world of chemistry probably don’t know much about.

One of these is , which was the subject of my postgraduate degrees in chemistry, and which I have been studying for almost 30 years. In chemistry, gold can be considered a late starter when compared to most other metals. It was always considered to be chemically “inert” – but in recent decades it has flourished and a variety of interesting applications have emerged.

Biophotonic therapy eliminates bacteria and viruses from organs before transplantation

Posted by in category: biotech/medical

A new technique for the decontamination of organs before transplantation using ultraviolet and red light irradiation has been developed by Brazilian and Canadian researchers and is described in an article titled “Inactivating hepatitis C virus in donor lungs using light therapies during normothermic ex vivo lung perfusion,” published in the journal Nature Communications. The research was partially conducted at the Optics and Photonics Research Center (CEPOF), hosted by the University of S\xE3o Paulo (USP) at S\xE3o Carlos in S\xE3o Paulo State (Brazil).

“This biophotonic technique is revolutionary, as it helps avoid the transmission of diseases during ,” said Vanderlei Bagnato, full professor at the University of S\xE3o Paulo, director of its S\xE3o Carlos Physics Institute (IFSC-USP), and principal investigator for CEPOF.

Bagnato’s group partnered with researchers at the University of Toronto in Canada, which has the world’s largest lung transplantation program, having performed 197 such surgeries in 2018 alone. According to thoracic surgeon Marcelo Cypel, who heads the service, the number of transplants could be higher if organs could be decontaminated, especially when the prospective donor has a such as hepatitis C.

SpaceX will launch NASA’s mission to crash spacecraft into an asteroid

Posted by in category: space travel

SpaceX will launch NASA’s $69 million mission to crash a spacecraft into an ASTEROID in 2021 to test methods that could save Earth from deadly impacts…


The groundbreaking mission will be the first demonstrated attempt to deflect an asteroid by purposely crashing an object into it at high speed.

After launching from California’s Vandenberg Air Force base atop a Falcon 9 rocket in 2021, the DART craft is expected to reach the object Didymos in October 2022, when it’s 11 million kilometers (6.8 million miles) from Earth.

A future ‘human brain/cloud interface’ will give people instant access to vast knowledge via thought alone

Posted by in categories: biotech/medical, education, nanotechnology, robotics/AI

Imagine a future technology that would provide instant access to the world’s knowledge and artificial intelligence, simply by thinking about a specific topic or question. Communications, education, work, and the world as we know it would be transformed.

Writing in Frontiers in Neuroscience, an international collaboration led by researchers at UC Berkeley and the US Institute for Molecular Manufacturing predicts that exponential progress in nanotechnology, nanomedicine, AI, and computation will lead this century to the development of a “Human Brain/Cloud Interface” (B/CI), that connects brain cells to vast cloud-computing networks in real time.

Environmentalists are Wrong: Nature Isn’t Sacred and We Should Replace It

Posted by in categories: biotech/medical, ethics, food, information science, life extension, robotics/AI, space, sustainability, transhumanism

Environmentalism and climate change are increasingly being pushed on us everywhere, and I wanted to write the transhumanism and life extension counter argument on why I prefer new technology over nature and sustainability. Here’s my new article:


On a warming planet bearing scars of significant environmental destruction, you’d think one of the 21st Century’s most notable emerging social groups—transhumanists—would be concerned. Many are not. Transhumanists first and foremost want to live indefinitely, and they are outraged at the fact their bodies age and are destined to die. They blame their biological nature, and dream of a day when DNA is replaced with silicon and data.

Their enmity of biology goes further than just their bodies. They see Mother Earth as a hostile space where every living creature—be it a tree, insect, mammal, or virus—is out for itself. Everything is part of the food chain, and subject to natural law: consumption by violent murder in the preponderance of cases. Life is vicious. It makes me think of pet dogs and cats, and how it’s reported they sometimes start eating their owner after they’ve died.
