Two Americans, One Dane Win Chemistry Nobel

Published

on

The Nobel Chemistry Prize was on Wednesday awarded to a trio of chemists from the US and Denmark who laid the foundation for a more functional form of chemistry.

Americans Carolyn Bertozzi and Barry Sharpless, together with Denmark’s Morten Meldal, were honoured “for the development of click chemistry and bioorthogonal chemistry,” the jury said.

The award marks the second Nobel for 81-year-old Sharpless, who won the chemistry Nobel in 2001.

Only four other individuals have achieved the feat, including Polish-born Frenchwoman Marie Curie.

Click chemistry “is an elegant and efficient chemical reaction that is now in widespread use,” the jury said in a statement.

“Among many other uses, it is utilised in the development of pharmaceuticals, for mapping DNA and creating materials that are more fit for purpose,” it added.

“This year’s Prize in Chemistry deals with not overcomplicating matters, instead working with what is easy and simple,” Johan Aqvist, Chair of the Nobel Committee for Chemistry, said in the statement.

The trio will share the Nobel award sum of 10 million Swedish kronor ($917,500), will receive the prize from King Carl XVI Gustaf at a formal ceremony in Stockholm on December 10, the anniversary of the 1896 death of scientist Alfred Nobel who created the prizes in his last will and testament.

Sharpless, a professor at Scripps Research in California, “started the ball rolling” and “coined the concept of click chemistry” around 2000, the jury said.

“Shortly afterwards, Morten Meldal and Barry Sharpless –- independently of each other –- presented what is now the crown jewel of click chemistry: the copper catalysed azide-alkyne cycloaddition,” the jury said.

Meldal, 68, is a professor of chemistry at the University of Copenhagen.

Bertozzi, who is a professor at Stanford in the United States, then took it to “a new level.”

“She developed click reactions that work inside living organisms. Her bioorthogonal reactions take place without disrupting the normal chemistry of the cell,” the jury said.

“I’m absolutely stunned, I’m sitting here and I can hardly breathe,” Bertozzi told reporters via telephone, minutes after the announcement.

Last year, the academy honoured Germany’s Benjamin List and US-British dual national David MacMillan for their development of a precise tool for molecular construction known as asymmetric organocatalysis.

On Monday, the medicine prize went to Swedish paleogeneticist Svante Paabo for his discoveries on the genomes of extinct hominins and human evolution.

Then on Tuesday, physicists Alain Aspect of France, John Clauser of the United States and Austria’s Anton Zeilinger were given the physics prize for developing experimental tools that helped prove quantum entanglement — a phenomenon Albert Einstein dismissed as “spooky action at a distance”.

The chemistry prize will be followed by the highly watched literature and peace prizes, announced on Thursday and Friday respectively.

The peace prize is expected to hold a special significance this year given the Russian invasion of Ukraine.

Ghana is looking to supply Nigeria with its electricity needs following power grid shutdown

Published

on

LAGOS- With the goal of achieving “100% universal energy access” and maybe exporting electricity to its neighbor, Nigeria, Ghana has steadily been developing its power sector.

During his presentation in Lagos on the second day of the Nigeria Energy Leadership Summit, Mr. Hanson Monney, the Head of the Generation and Transmission Unit at the Ghanaian Ministry of Energy, made this point, emphasizing that via effective policy development and implementation, Ghana has already attained an impressive 80% to 85% universal energy access inside its boundaries.

“So, we are working on all these things to make sure that the power system of Ghana continues to be as good as it is or even better, and then, maybe, we can be exporting more to our big brothers in Nigeria when the grid is finally settled,” Mr. Hanson Monney said

This declaration follows the second national power grid breakdown in Africa’s most populous country and the continent’s top oil producer, Nigeria which resulted in a total blackout of homes and businesses.

In contrast, Ghana is aggressively pursuing a variety of energy sources, including grid electricity, mini-grids, and solar-dominated renewable energy, to attain “Universal access to energy by 2024” as instructed by the country’s President.

Monney agreed that the geographic limitations make it difficult to provide everyone in Ghana with access to electricity, particularly on isolated islands, riverbanks, or lakeside villages. In response to this, he stated,

“So, now, we are trying to scale our renewable energy access, and that is how we have planned in 2022 to scale up our renewable energy program,” he said.

Financial sustainability is one of the biggest problems facing Ghana’s power sector, as the country struggles with growing debts and the purchase of surplus capacity.

“There is so much debt that the government has to shore up to make sure that the system is afloat because we have procured a lot of excess capacity, which comes with attendant costs. So, these financial challenges require some policy actions to eliminate legacy debts,” Mooney stated.

Monney stressed the significance of lowering electricity prices, particularly for enterprises, since high electricity bills are a major issue in Ghana. “We saw that in Ghana historically. These industries have been subsidizing the residential sector, and it should be the other way around. Industries should remain viable so that businesses can thrive,” Mooney stated.
