Scientists Susumu Kitagawa, Richard Robson and Omar Yaghi yesterday won the Nobel Prize in Chemistry for developing a new form of molecular architecture, yielding materials that can help tackle challenges such as climate change and lack of fresh water.
The laureates worked to create molecular constructions, known as metal-organic frameworks (MOFs), with large spaces through which gases and other chemicals can flow and that can be utilized to harvest water from desert air, capture carbon dioxide or store toxic gases.
Describing the “unheard of properties” of the materials, the award committee said some had a remarkably large surface area — a porous material about the size of a small sugar cube could contain as much surface area as a large soccer pitch.

“A small amount of such material can be almost like Hermione’s handbag in Harry Potter. It can store huge amounts of gas in a tiny volume,” Nobel Committee for Chemistry member Olof Ramstrom said.
The more than century-old prize is awarded by the Royal Swedish Academy of Sciences and the winners share 11 million kronor (US$1.2 million), as well as the fame of winning arguably the world’s most prestigious science award.
Kitagawa told the Nobel news conference that he was deeply honored by the award.
“My dream is to capture air and separate air to — for instance, in CO2 or oxygen or water or something — and convert this to useful materials using renewable energy,” he said.
After the discoveries, chemists have built tens of thousands of different MOFs, some of which “may contribute to solving some of humankind’s greatest challenges,” the academy said, adding that additional uses included separating toxic polyfluorinated alkyl substances, or “forever chemicals,” from water and breaking down traces of pharmaceuticals in the environment.
Kitagawa is Japanese, Robson was born in the UK, but moved to Australia in his late 20s, while Yaghi is Jordanian-American.
A signaling system malfunction disrupted high-speed rail (HSR) services beginning at 8am today, with trains temporarily reduced to three northbound and three southbound trains per hour as authorities conduct inspections. The malfunction occurred on a section of track in Miaoli County during pre-operation checks early this morning, forcing northbound and southbound trains to use a single track, the HSR operator said. The regular schedule has been replaced with three hourly trains offering only nonreserved seating in each direction, stopping at every station, it said, adding that business class cars would still have reserved seating. Departures from terminal stations are scheduled at the top
Taiwan is still in the process of assessing the possibility of recruiting workers from Eswatini, the Ministry of Foreign Affairs said yesterday, adding that its goal is to help Eswatini upgrade its vocational training centers. If there are plans to recruit workers from Eswatini, safeguarding national security, protecting public health and ensuring the employment rights of Taiwanese would be prerequisites, Department of West Asian and African Affairs Director-General Yen Chia-liang (顏嘉良) told a news conference. Key considerations would also include filling labor shortages in specific industries, and fostering bilateral professional and technical exchanges, he said. Yen was asked about the progress of labor
A US uncrewed surface vessel (USV) encountered multiple Chinese warships during an autonomous transit of the Taiwan Strait, US defense company Seasats said in a statement on Wednesday. Seasats announced that a Lightfish USV had completed the first autonomous transit of the Taiwan Strait. Over five days, the USV traversed the entire length of the Strait while constantly monitoring surface vessel traffic, the company said. The Lightfish encountered multiple Chinese warships, one of which was a Chinese People’s Liberation Army Navy (PLAN) Type 056 corvette, it said. The Chinese vessels were operating “well within Taiwan’s exclusive economic zone without transmitting their identity via the
VERBOSE VESSELS: A CGA cutter and a China Coast Guard exchanged verbal barbs for more than a day in Taiwanese-controlled waters before the Chinese vessel left The Taiwanese and Chinese coast guards had a standoff near the strategically located Pratas Islands (Dongsha Islands, 東沙群島) in the north of the South China Sea, the Coast Guard Administration (CGA) said yesterday. The two sides engaged in intense radio exchanges over sovereignty claims during the 33-hour standoff. China Coast Guard vessel 3501 eventually left the restricted waters, 26.6 nautical miles (49.2km) west of the Pratas Islands, at 5pm yesterday, the CGA said. Lying approximately between southern Taiwan and Hong Kong, the Taiwan-controlled Pratas are seen by some security experts as vulnerable to Chinese attack due to their distance — more than
