Beijing: A reusable uncrewed space vehicle returned to Earth on Monday morning after spending 276 days in orbit, according to a media report.

There is not much information about the space vehicle as China’s space authorities have not released any pictures or technical data, and experts suspect it could be used to gather intelligence, South China Morning Post reported.

The reusable experimental spacecraft, was launched with a Long March-2F rocket from the Jiuquan satellite centre in Inner Mongolia in 2020.

Space defence contractor China Aerospace Science and Technology Corporation said the classified mission is a “complete success” and “marks an important breakthrough” in China’s research into the technology.

The reusable spacecraft “will provide a more convenient and cost-effective way for peaceful use of space”, the company was quoted as saying.

The spacecraft resembles the US Air Force’s Boeing X-37B, Xinhua news agency had reported earlier.

The X-37B is an unmanned space plane that operates like a smaller version of the Space Shuttle, which is launched by a rocket and cruises back to earth for a runway landing. It has flown four classified missions to date, carrying secret payloads on long-duration flights in Earth orbit.

According to some experts, the Chinese craft could be equipped with advanced imaging and sensing equipment to gather intelligence on potential targets or monitor sensitive areas of interest, the report said.

Another potential use is the deployment of small satellites or other payloads into orbit. This could include communications satellites, navigation systems, or other types of sensors that could be used for military or government purposes.

Researchers at the Indian Institute of Science Education and Research (IISER) Bhopal have created a new family of organic molecules that emit light in the near-infrared (NIR) range, opening possibilities for OLEDs for various applications.

Light-emitting diodes or LEDs are tiny light-emitting devices that are commonly used in applications such as television screens, gadget displays, etc. They are different from traditional filament bulbs in that while bulbs emit light when heated, LEDs emit light when electricity (in the form of electrons) passes through them.

OLEDs are a form of LEDs where the light emitting materials are organic molecules — chemicals made largely of carbon and hydrogen.

Although visible light-emitting OLEDs have already found mass application in displays for gadgets, televisions, and lighting, producing NIR-emitting OLEDs is challenging due to their unique molecular energy structure.

Light-emitting molecules generate light when electrons fall from a high energy state (HOMO) to a low energy state (LUMO) inside the molecule, and the colour of the emitted light depends on the energy difference between the two states. The energy difference in organic molecules corresponds to visible light, making visible light-emitting OLEDs easier to design.

The team at IISER created new organic molecules that have a very low-energy LUMO. This means that the energy difference between LUMO and HOMO is smaller, resulting in near-infrared light.

“We have achieved a nitro group containing polycyclic aromatic molecules that exhibit fluorescence (light emission) in the near-IR wavelengths,” said Prof. Jeyaraman Sankar, IISER Bhopal, in a statement.

The team’s new approach to obtaining stable electron-deficient molecules with NIR emission using nitration as a strategy is unique and has been published in the journal of the Royal Society of Chemistry – Chemical Science.

The innovation lay in fine-tuning the structure of the nitro-group-containing molecules that typically do not fluoresce and are therefore usually non-light-emitting.

Another challenge is to position the emission in the near-IR region. The team engineered the structure of the molecules such that they emit near-IR light. In addition, the synthesised molecules show strong electron affinity values, excellent stability, and structural rigidity.

The fluorescence quantum yields (the amount of near-IR light emitted) are among the best for any known near-IR light-emitting electron-deficient materials, the team said.

Apart from their use in OLED applications, the strong electron affinity, NIR emissive nature, high stability, and redox robustness of these molecules make them excellent candidates for catalysts.

These molecules can also be used for near-IR devices that help in side effect alleviation, after selected chemotherapy procedures.

The potential applications for near-IR-emitting OLEDs are vast, including biomedical sensors, short-range communication, night vision, and security.

The discovery could potentially extend the use of organic light-emitting devices beyond visible light, with implications in a range of applicationsAfrom medical equipment to advanced security gadgets, the researchers said.

San Francisco:  Leading biotechnology company Twist Bioscience Corporation has announced to lay off 270 people, or about 25 per cent of its workforce, as it aims to accelerate its path to profitability.

The company enables customers to succeed through its offering of high-quality synthetic DNA using its silicon platform.

Twist said it will focus resources on the support of key commercial and development opportunities that have the potential to deliver significant return on investment.

“Twist conducted a comprehensive review of the business and is resizing many teams throughout the organisation and reducing its workforce by approximately 270 employees, or about 25 per cent,” it said while delivering its fiscal second quarter 2023 financial results.

The biopharma team has been resized to focus on revenue-generating partnerships and Twist said it will moderate its investment in DNA data storage while maintaining its competitive lead.

“We reported a strong quarter overall, breaking the $60 million revenue threshold for the first time and exceeding our guidance,” said Emily M. Leproust, CEO and co-founder of Twist Bioscience.

“In January, we shipped the first products from the Factory of the Future and are now manufacturing the vast majority of our genes, gene fragments and oligo pools in our Wilsonville facility,” Leproust added.

Additionally, Twist plans to maintain its global commercial presence to drive top-line growth while streamlining teams including R&D across the business to focus on programmes, where the company believes it has a clear competitive advantage and sees the greatest potential for long-term profitable growth and value creation.

“Following a strategic and holistic analysis of the business, we prioritised and reengineered our cost base, and with these substantive changes, we believe we are operating from a position of strength, operating as a leaner organisation,” said the company CEO.

San Francisco:  After its initial release earlier this year, Google has now made Android’s Nearby Share feature available for Windows PCs to nearly all countries worldwide, signalling a significant expansion in its accessibility.

“We are very excited to announce that Nearby Share for Windows is now available worldwide, so even more of your devices can work better together,” Google said in a blogpost.

Through Nearby Share, Android users can share files wirelessly with their PCs, whether they are desktops or laptops, and through Android’s native menus.

Google initially limited the feature to only a few countries, with a primary focus on the US.

Now, according to Google’s support page, Nearby Share Beta for Windows PCs is available in the US and most countries globally, however, support is currently not available for Cuba, Iran, North Korea, and Syria.

Users can easily set Nearby Share Beta for Windows by just downloading and installing the app on their PCs.

Users then be able to send files to nearby Android devices or send files to their PC based on their device visibility preferences.

Meanwhile, Google has rolled out new Material You design for its Nearby Share app on Android phones and tablets.

The Material You revamp brings visual changes to the main UI users interact with on the Nearby Share app.
