NASA’s Perseverance rover has successfully completed an experiment designed to create oxygen on Mars, using a technique that could one day provide astronauts with breathable air, and be used as a key ingredient in rocket fuel for a return journey home.

Humanity is looking to expand deeper into the solar system, first by establishing a permanent base on the Moon, before finally placing human boots on Mars for the first time in our species’ short history. For this to be a reality, both NASA and its partners need to develop new technologies that will make use of the natural resources of those distant worlds to ensure that future missions are as self reliant as possible.

One major problem faced by astronauts visiting Mars is ensuring they have a ready supply of breathable air. Oxygen on Earth is relatively abundant, making up roughly 21 percent of our planet’s atmosphere. However, the gasseous shell enveloping Mars is composed of less than one percent oxygen, and 96 percent carbon dioxide, with nitrogen, argon, and other myriad trace gases making up the remainder.

Astronomers from the University of Maryland and the Michigan Technological University, have inspected a mysterious ultra-high energy gamma-ray source known as LHAASO J2108+5157. Results of the study, published August 31 on the pre-print server arXiv, could help us unveil the true nature of this source.

Sources emitting gamma radiation with photon energies between 100 GeV and 100 TeV are called very-high energy (VHE) gamma-ray sources, while those with photon energies above 0.1 PeV are known as ultra-high energy (UHE) gamma-ray sources. The nature of these sources is still not well understood; therefore, astronomers are constantly searching for new objects of this type to characterize them, which could shed more light on their properties in general.

A team of astronomers led by University of Maryland’s Sajan Kumar decided to take a closer look at one such UHE gamma-ray source designated LHAASO J2108+5157. It is a point-like source with an extension less than 0.39 degrees, known to be associated with the molecular cloud [MML2017]4607—located some 10,700 light years away.

Industrial Internet of Things (IIoTs) refers to a technology that combines wireless sensors, controllers, and mobile communication technologies to make every aspect of industrial production processes intelligent and efficient. Since IIoTs can involve several small battery-driven devices and sensors, there is a growing need to develop a robust network for data transmission and power transfer to monitor the IIoT environment.

In this regard, wireless power transfer is a promising technology. It utilizes radio frequency signals to power small devices that consume minimal power. Recently, simultaneous wireless information and power transfer (SWIPT), which utilizes a single radio frequency signal to simultaneously perform energy harvesting and information decoding, has attracted significant interest for IIoTs.

Additionally, with smart devices rapidly growing in number, SWIPT has been combined with nonorthogonal multiple access (NOMA) system, which is a promising candidate for IIoTs due to their ability to extend the battery life of sensors and other devices. However, the energy efficiency of this system falls significantly with transmission distance from the central controller.

This program is designed to develop a means of distributing energy wirelessly around the globe through airborne power transfer. First dreamed up by Nikola Tesla almost 100 years ago, if successful, this would be the most significant change to energy transfer since the first rollout of electrification almost 150 years ago.

Amid the fierce competition throughout the globe to develop hydrogen mobility technologies to achieve carbon neutrality, a new technology for a 2-liter class hydrogen-fueled engine (a passenger car hydrogen engine) capable of running entirely on hydrogen has been developed for the first time in Korea.

The joint research team led by Principal Researcher Young Choi of the Department of Mobility Power Research of the Korea Institute of Machinery and Materials (KIMM), and Researcher Hong-gil Baek of the Zero-Carbon Engine Research Lab of Hyundai-Kia Motor Company (HMC) developed the “direct injection hydrogen engine” that runs entirely on hydrogen fuels, and demonstrated its world-class excellence through performance evaluation.

The joint research team of KIMM and HMC injected hydrogen directly into the combustion chamber of the engine of HMC’s existing hybrid vehicle, with a pressure of more than 30 bar. By using a turbo charger that improves the performance of the engine, the research team was able to maintain high thermal efficiency in all domains from the ignition of the engine to the upper limit of the engine load, allowing the engine to be stably operated throughout the entire engine operating conditions.

New technology allows hydrogen to be directly injected into the cylinders like an internal combustion engine.

As the world scrambles to transition to green fuels to achieve carbon neutrality, promoting power sources that use hydrogen as a clean fuel is one strategy to further the move. Now, researchers in South Korea have developed a new technology for a passenger car hydrogen engine that promises to make it more viable for mass production.

The powertrain developed by researchers at the Korea Institute of Machinery and Materials (KIMM) and the Zero-Carbon Engine Research Lab of Hyundai-Kia Motor Company (HMC) is a 2-liter direct injection hydrogen engine that runs entirely on hydrogen fuel.

Their research, recently published in the journal Nature, introduces a photocatalytic method that leverages light energy to activate water, potentially opening up new avenues in chemistry, particularly in the synthesis of compounds from simpler materials.

Removing membranes could shave off as much as 30 percent of battery costs since they are the most expensive components.

Researchers at the University of Cincinnati in the US have developed a new design that could make lithium-ion batteries much cheaper to produce. This can have a profound impact on the large-scale energy storage systems needed to store renewable energy, a press release said.

Lithium-ion batteries, extensively used for power electronic devices, have also found their way into electric vehicles (EVs) thanks to their superior energy density over conventional batteries. These can also be deployed to store renewable energy when production is high, but the demand is low.
