Researchers create 2D all-organic perovskites and demonstrate potential use in 2D electronics

Posted by in categories: chemistry, solar power, sustainability

Perovskites are among the most researched topics in materials science. Recently, a research team led by Prof. LOH Kian Ping, Chair Professor of Materials Physics and Chemistry and Global STEM Professor of the Department of Applied Physics of The Hong Kong Polytechnic University (PolyU), Dr Kathy LENG, Assistant Professor of the same department, together with Dr Hwa Seob CHOI, Postdoctoral Research Fellow and the first author of the research paper, has solved an age-old challenge to synthesise all-organic two-dimensional perovskites, extending the field into the exciting realm of materials. This breakthrough opens up a new field of 2D all-organic perovskites, which holds promise for both fundamental science and potential applications.

This research was published in the journal Science (“Molecularly thin, two-dimensional all-organic perovskites”).

Perovskites are named after their structural resemblance to the mineral calcium titanate perovskite, and are well known for their fascinating properties that can be applied in wide-ranging fields such as solar cells, lighting and catalysis. With a fundamental chemical formula of ABX 3, perovskites possess the ability to be finely tuned by adjusting the A and B cations as well as the X anion, paving the way for the development of high-performance materials.

New high-throughput device to unlock the potential of advanced materials

Posted by in categories: chemistry, engineering, nanotechnology, sustainability

A Birmingham researcher has developed a new high-throughput device that produces libraries of nanomaterials using sustainable mechanochemical approaches.

Dr. Jason Stafford from the University’s School of Engineering invented the platform to create highly controllable reaction conditions and reduce the substantial amount of time researchers spend generating materials in the laboratory.

The benchtop device is a fully automated unit that can be programmed for parallel synthesis to produce a series of novel materials made in subtly different ways, so creating a library of or product formulations for further testing and optimization.

Nanoparticle catalysts convert carbon dioxide to carbon monoxide to make useful compounds

Posted by in categories: climatology, nanotechnology, sustainability

As a greenhouse gas, carbon dioxide (CO2) contributes to climate change as it accumulates in the atmosphere. One way to reduce the amount of unwanted CO2 in the atmosphere is to convert the gas into a useful carbon product that can be used to generate valuable compounds.

One quarter of German car exports in 2023 were fully electric, earning $62 billion

Posted by in categories: sustainability, transportation

The number of electric vehicles (EVs) exported from Germany rose sharply in 2023, meaning that EVs accounted for about one quarter of all car exports that year, the country’s statistical office Destatis has said.

The country exported about 786,000 fully electric cars for a total value of roughly €36 billion ($A61.8 billion) – an increase of 58 per cent compared to 2022.

The most important destinations for EVs produced in Germany were the Netherlands, the UK and Belgium, Destatis added. Imports of EVs to Germany climbed about 23 percent to 446,000 units, with more than a quarter coming from China.

Fusion Breakthrough: 6 Minutes of Plasma Sets New Reactor Record

Posted by in categories: nuclear energy, sustainability

A fusion reactor in southern France, called WEST, just achieved an important milestone that brings us one step closer to clean, sustainable, nearly limitless energy.

Scientists at New Jersey’s Princeton Plasma Physics Laboratory, who collaborated on the project, announced today that the device created a super-hot material called a plasma that reached 90 million degrees Fahrenheit (50 million degrees Celsius) for 6 straight minutes.

The ultimate goal is to sustain a super-hot plasma for many hours, but 6 minutes is a new world record for a device like WEST. Other nuclear reactors similar to WEST have created hotter plasmas, but they haven’t lasted as long.

China’s new water-based battery can revolutionize EVs

Posted by in categories: energy, sustainability, transportation

Researchers in China have developed a water-based battery, which is claimed to be much safer and energy-efficient than “highly flammable” non-aqueous lithium batteries.

Interestingly, the researchers say that these new batteries will be twice as energy-dense as traditional lithium-ion options. This holds the potential to revolutionize the electric vehicle industry.

Moreover, aqueous batteries use water as the solvent for electrolytes, enhancing their safety. Traditional non-aqueous lithium-ion batteries have a high energy density, but their safety is compromised due to the flammable organic electrolytes, a component that allows the battery to charge and discharge, they utilize.

Unleashing Disordered Rocksalt Oxides as Cathodes for Rechargeable Magnesium Batteries

Posted by in categories: chemistry, particle physics, sustainability

Researchers at Tohoku University have made a groundbreaking advancement in battery technology, developing a novel cathode material for rechargeable magnesium batteries (RMBs) that enables efficient charging and discharging even at low temperatures. This innovative material, leveraging an enhanced rock-salt structure, promises to usher in a new era of energy storage solutions that are more affordable, safer, and higher in capacity.

Details of the findings were published in the Journal of Materials Chemistry A on March 15, 2024.

The study showcases a considerable improvement in magnesium (Mg) diffusion within a rock-salt structure, a critical advancement since the denseness of atoms in this configuration had previously impeded Mg migration.
