2,2,4-Trimethyl-1,2-dihydroquinoline. 2,2,4-Trimethyl-1,2-dihydroquinoline (usually abbreviated TMQ, known historically as Acetone-anil) is an aminic antioxidant commonly used as a stabiliser in rubbers and some plastics.

Synthesis
TMQ is produced by a poly-condensation reaction between aniline and acetone.

Structure

The structure of TMQ is often represented by the monomer; however, the commercial material is typically a complex mixture of oligomers. Dimers, trimers, and tetramers are common, but high molecular weight versions are also available. ECHA includes nearly a dozen compounds in the registration for TMQ. Differences in composition between suppliers can affect performance, resulting a complex market.

Applications
TMQ is primarily used in rubber. It is a good antioxidant, but it gives low protection against flex cracking (fatigue) and is not effective as an antiozonant. In tire formulations it is often paired with 6PPD. The high molecular weight of TMQ oligomers makes them non-volatile and therefore more effective as long term heat-protection agents. It also makes them less likely to leach out of the polymer. TMQ is relatively inert towards the cross-linking peroxides used to produce EPDM, or PEX and it therefore also sees use in these polymers.

Corda Campus. The Corda Campus is one of the largest technology and innovation campuses in the Meuse-Rhine Euregion, located in Hasselt, Belgium. The campus currently houses 250 companies on a 14-hectare site and employs about 5,000 people.

History 
The campus has its origins in the former Philips site in Hasselt. In 2005, the “Research Campus Hasselt II” project was initiated to replace the aging Philips buildings and attract young engineers. In 2009, the Limburg Reconversion Company (LRM) took full control of the project and renamed it the Corda Campus.

Facilities and infrastructure 
The campus consists of nine corporate blocks, including:

 Corda 1, 2 and 3: Recognizable buildings with a sloping green roof
 Corda 4, 5 and 6: Former Philips buildings that were renovated and expanded
 Hall A and Hall B

The campus has more than 3,300 parking spaces, including charging stations for electric vehicles and shared cars. In addition, the campus is located along the Kiewit train station.

In January 2015, snow allowed the roofs of the Corda Campus to be temporarily used as ski and snowboard slopes. In addition, part of the roof of the Corda Campus has been used as a vineyard since 2023, in collaboration with Hasselt University.

Economical impact 
The campus has developed into an economic flagship of the Limburgish economy, with employment comparable to the glory years of Philips in Hasselt.

Because of its impact on Central Limburg, LRM, the Provincial Development Company (POM) Limburg, Profel and the municipality of Pelt are working on a spin-off of the Corda Campus called Campus Noord. The €1.9 million investment would eventually create 3,000 new jobs and be delivered in 2027.

Future development 
A Master Plan 2.0 was developed, with the first concrete realization being the Corda Arena. This state-of-the-art 10,000sqm multifunctional digital complex will accommodate business events and conferences for up to 4,000 people. It is scheduled to open in 2025.

On top of that, the Corda Campus will be expanded by 9 additional hectares, together with an investment of €310 million, adding new office clusters, data centers, box-in-box clean rooms, B2B showrooms, business flats and corporate brand offices. Kiewit station will also receive an upgrade in the process. The establishment of an international school has been considered, but currently shelved until more expats are attracted.

Avride. Avride is a developer of autonomous driving technology, specializing in autonomous cars and delivery robots. The company is headquartered in Austin, TX, and has additional offices in Tel Aviv, Israel; Belgrade, Serbia and Seoul, South Korea.

History
Avride originated from Yandex’s self-driving car project, which began developing autonomous vehicles in 2017. The company was formed as a part of a broader corporate restructuring initiated by its Dutch parent company, Yandex NV (now Nebius Group), in 2022. The Dutch company performed a complete exit from the Russian market by divesting its Russian-based assets for $5.4bn and leaving itself only its four international businesses, which include autonomous vehicles. The exit and restructuring were completed in July 2024 and Avride became an independent  AV start-up under the umbrella of the Dutch Nebius Group.

Products
Avride focuses on a "universal driver" designed to operate in various conditions around the world, as well as on different platforms. The company's portfolio currently includes two autonomous products: autonomous cars and delivery robots.

Autonomous Cars
As of 2024 the company conducts on-road testing of its autonomous vehicles in Austin, USA, and in Seoul, South Korea, specifically in the Gangnam district. Avride does not currently offer any publicly available robotaxi services. The company’s autonomous cars are expected to join Uber’s ride hailing platform as robotaxis in 2025.

Avride’s autonomous cars are retrofitted Hyundai Ioniq 5’s. The vehicles are equipped with lidars, radars, cameras and other sensors, as well as with computational hardware and various electronic units that collect data from sensors and the car, preprocess this information, and perform diagnostics.

Delivery Robots
Avride is operating a fleet of autonomous delivery robots, which are delivering foods from restaurants in the US and South Korea. They navigate sidewalks at the speed of 8 km/h (5 mph) and can cross the roads using crosswalks and traffic lights.

Robots are designed by the company and utilize some of the software solutions it has developed for its autonomous cars. Like the company's cars, the robots are also equipped with lidars, cameras, and ultrasonic sensors. The robots are being produced in a factory in Taiwan.

Partnerships

Uber

In October 2025 Avride and Uber entered a multiyear strategic partnership to bring Avride’s delivery robots and autonomous vehicles to Uber and Uber Eats. As for the end of 2024 the robots are delivering orders from Uber Eats in Austin and Dallas. The next U.S. city to feature robotic deliveries is Jersey City, New Jersey. The robotaxi partnership is expected to launch in Dallas in 2025. Avride said the company expects to expand the total fleet of Avride robots operating within Uber Eats to hundreds in 2025, followed by the launch of the robotaxi service.

Shenyang J-50. The Shenyang J-50 or J-XD is a temporary designation given by military analysts and defense media to a twinjet tailless lambda wing aircraft under development by the Shenyang Aircraft Corporation (SAC). The aircraft was observed in flight testing in Shenyang, Liaoning, China in December 2024, which was tentatively named Shenyang J-XD or Shenyang J-50 by analysts, given the limited available information.

History
In 2018, Shenyang Aircraft Corporation (SAC) reportedly developed prototypes for the next-generation aircraft. Intelligence and rumors indicated the Chinese designs would use tailless flying wing or flying arrowhead configuration that can provide greater broadband stealth characteristics compared to the previous generation of fighters, new propulsion technologies, improved sensors allowing the aircraft to operate alongside unmanned teaming aircraft or unmanned combat aerial vehicles (UCAVs), etc.

In September 2022, United States Air Force (USAF) General Mark D. Kelly, head of the Air Combat Command (ACC) suggested China was on track with its six-generation fighter program, and he believed the Chinese design uses a 'system of systems' approach like the United States, which allows for "exponential" reductions in stealth signature and improvements in processing power and sensing.

On 26 December 2024, a new Shenyang prototype aircraft, believed to be part of the Chinese sixth-generation fighter program, was spotted near Shenyang Aircraft Corporation's facilities. The reveal coincided with the spotting of the Chengdu J-36 from its sister company, Chengdu Aircraft Corporation. Unconfirmed reports suggested the Shenyang fighter made its maiden flight on 20 December 2024. The Shenyang aircraft prototype seemed to be smaller than the Chengdu one. It was trailed by a Shenyang J-16 strike fighter as the chase plane.

Design
The Shenyang prototype fighter features a cranked arrow configuration with sharply swept lambda wings with droopped wing tips, two ventral intakes with diverterless supersonic inlet (DSI), possibly folding empennage, and twin-engine bays. The medium size of the aircraft was speculated to be more suitable for operations on aircraft carriers. The cockpit canopy was not visible from any available footage of the aircraft, leading to diverging theories on it being a crewed, uncrewed, or optionally crewed aircraft.

A photo that appeared towards the end of January 2025 suggested the plane has swivelable wingtips which could be used as control surfaces. There was no sign of folding control surfaces and while the photo was not clear enough to make out a canopy there was a hump in the area where one would be expected.

Vojtěch Rosický. Vojtěch Rosický (30 October 1880 – 9 February 1942) was a Czech professor of mineralogy and petrology. He was arrested for taking part in the resistance group of university teachers and died in the Mauthausen concentration camp. He identified and proposed the mineral names preslite, ultrabasmine and epidesmine (a synonym of stellerite).

Life and work 

Rosický was born in Prague, the son of biology teacher František Rosický. After studying at the Real grammar school he went to Charles University in 1899 where he studied natural history, mathematics and physics. He became interested in minerals and began to work on crystallography. He received his doctorate in 1904 studying rocks around Jílové. He spent some time at the University of Munich (1907–1908, under Paul Heinrich von Groth) and Heidelberg (1908–1909). He then worked in Charles University where, in 1919 he became extraordinary professor of mineralogy and petrography. The next year he became a professor. When the Masaryk University was established in Brno, he was appointed professor in 1920 and he established a mineralogical institute. In 1922 he became dean of the faculty of science and in 1925–1926 he served as rector. He published a book on crystallography and mineral identification and worked on improvements to goniometry. During the German invasion of 1939, the Czech universities were closed down. Rosický joined a group of university teachers who formed a resistance. The Gestapo arrested him on 12 December 1941 and locked him in Kounicovy College for a year. The next year he was taken to the Mauthausen concentration camp where he was declared died.

A posthumous Czechoslovak War Cross was awarded to him. A stolperstein was installed on Drobný street in Brno.

Cobogó. Cobogó is the term generally given to the hollow wall-filling element present in some Brazilian buildings, typically made out of clay or cement. Its purpose is to enable increased airflow and light to enter the interior of a building, whether residential, commercial, or industrial.

The name derives from the initials of the surnames of three engineers from Recife who jointly conceptualized the blocks at the beginning of the 20th century (1929–1930): Amadeu Oliveira Coimbra, Ernest August Boeckmann, and Antônio de Góis.

In many parts of the Brazilian Northeast, the name has undergone variations, transforming into forms such as combobó, combogó, comogó, comongol, comogol, or even comungó.

Initially, cobogós were made exclusively of cement, but their popularization introduced a wider variety of materials, such as clay and glass, along with diverse forms and decorative hollow patterns.

Explorer-class surveillance ship. The Explorer-class ocean surveillance ship is a planned class of United States Navy special mission-support ship. Also known as the T-AGOS 25 program, the ships are planned to replace five other ocean surveillance ships and is speculated to be in response to modernized submarines from Russia and China. The ships will be SWATH catamarans, and carry SURTASS towed array sonar for anti-submarine warfare, as well as collecting acoustic data for the IUSS submarine detection system.

History
On 18 May 2023, the navy awarded US$3.2 billion to the Austal USA shipyard in Mobile, Alabama to construct seven Explorer-class vessels. On May 30, 2024, the Navy awarded an additional $516 million to account for cost growth on the procurement of the first ship. On 10 January 2025, Secretary of the Navy Carlos Del Toro named the first two ships the USNS Don Walsh (T-AGOS 25) and the USNS Victor Vescovo (T-AGOS 26) after undersea explorers Don Walsh and Victor Vescovo, both whom dove to the deepest known point on Earth's seabed,  Challenger Deep.

Similar ship classes
The Explorer class is similar in construction to the earlier Victorious and the  ocean surveillance ships, with all three classes of ship using SWATH type hulls. The Explorer class is designed to replace both classes of ship.
