Editors have highlightedthe following attributes while ensuring the content's credibility: fact-checked peer-reviewed publication trusted source proofread by Max Planck Society Nickel and nitrogen co-doped carbon (Ni-N-C) catalysts have shown exceptional performance in converting CO 2 into CO, a valuable chemical feedstock. However, the exact working mechanism of these catalysts has remained elusive—until now. The study "Unveiling the Adsorbate Configurations in Ni Single Atom Catalysts during CO 2 Electrocatalytic Reduction using Operando XAS, XES and Machine Learning" provides direct experimental insights into the nature of adsorbates (molecules that stick to the catalyst 's surface) forming at the nickel sites and the evolving structure of the active sites during the CO 2 reduction reaction (CO 2 RR). The work is published in the journal Physical Review Letters . The research team employed advanced techniques like operando hard X-ray absorption spectroscopy (XAS) and valence-to-core X-ray emission spectroscopy (vtc-XES) to observe the catalysts in action. These advanced methods, combined with machine learning and density functional theory, allowed the team to map out the local atomic and electronic structure of the catalysts in unprecedented detail. This work illustrates the power of a multi-technique operando characterization approach combined with machine learning and modeling to extract in depth mechanistic insight. Understanding how nickel-based catalysts interact with CO 2 at the atomic level is crucial for their rational design aiming to improve their efficiency and selectivity. This knowledge can lead to the development of more effective and long-lived catalysts, making the CO 2 reduction process more viable for industrial applications . Essentially, this research helps pave the way for turning CO 2 , a greenhouse gas , into valuable resources like carbon monoxide (CO), which can be used in various industrial processes, including those where it can be combined with green hydrogen from water electrolysis for the synthesis of high order hydrocarbons. Imagine trying to bake a perfect cake without knowing how the ingredients interact in the oven and how the cake rises or eventually gets burnt during the baking. In the oven analogy, one can see through a window and use the visual information to make changes in the temperature and baking time. The present study is like having a high-tech camera that lets you see exactly how the ingredients mix and change as they bake, allowing you to tweak the recipe (and/or oven conditions) while you are baking for the best results. Similarly, by understanding how CO 2 interacts with nickel catalysts, scientists can fine-tune the process to generate the desired products more efficiently. This study not only enhances our understanding of nickel -based catalysts but also sets the stage for future advancements in CO 2 reduction technologies. By providing a detailed picture of how these catalysts work, the research opens up new possibilities for designing even more efficient systems for converting CO 2 into valuable products.

Parsons, who died at his Manhattan home, was diagnosed with multiple myeloma in 2015 and cited “unanticipated complications” from the disease for cutting back on work a few years later. The financial services company Lazard, where Parsons was a longtime board member, confirmed his death. The NBA, where Parsons was interim CEO of the Los Angeles Clippers in 2014, was among organizations offering condolences. “Dick Parsons was a brilliant and transformational leader and a giant of the media industry who led with integrity and never shied away from a challenge,” NBA Commissioner Adam Silver said. Parsons’ friend Ronald Lauder told The New York Times that the cause of death was cancer. Parsons stepped down Dec. 3 from the boards of Lazard and Lauder's company, Estée Lauder, citing health reasons. He had been on Estée Lauder’s board for 25 years. Parsons, a Brooklyn native who started college at 16, was named chairman of Citigroup in 2009, one month after leaving Time Warner Inc., where he helped restore the company’s stature following its much-maligned acquisition by internet provider America Online Inc. He steered Citigroup back to profit after financial turmoil from the subprime mortgage crisis, which upended the economy in 2007 and 2008. Parsons was named to the board of CBS in September 2018 but resigned a month later because of illness. Parsons said in a statement at the time that he was already dealing with multiple myeloma when he joined the board, but “unanticipated complications have created additional new challenges.” He said his doctors advised him to cut back on his commitments to ensure recovery. “Dick’s storied career embodied the finest traditions of American business leadership,” Lazard said in a statement. The company, where Parsons was a board member from 2012 until this month, praised his “unmistakable intelligence and his irresistible warmth.” “Dick was more than an iconic leader in Lazard’s history — he was a testament to how wisdom, warmth, and unwavering judgment could shape not just companies, but people’s lives,” the company said. “His legacy lives on in the countless leaders he counseled, the institutions he renewed, and the doors he opened for others.” Parsons was known as a skilled negotiator, a diplomat and a crisis manager. Although he was with Time Warner through its difficulties with AOL, he earned respect for the company and rebuilt its relations with Wall Street. He streamlined Time Warner’s structure, pared debt and sold Warner Music Group and a book publishing division. He also fended off a challenge from activist investor Carl Icahn in 2006 to break up the company and helped Time Warner reach settlements with investors and regulators over questionable accounting practices at AOL. Parsons joined Time Warner as president in 1995 after serving as chairman and chief executive of Dime Bancorp Inc., one of the largest U.S. thrift institutions. In 2001, after AOL used its fortunes as the leading provider of Internet access in the U.S. to buy Time Warner for $106 billion in stock, Parsons became co-chief operating officer with AOL executive Robert Pittman. In that role, he was in charge of the company’s content businesses, including movie studios and recorded music. He became CEO in 2002 with the retirement of Gerald Levin, one of the key architects of that merger. Parsons was named Time Warner chairman the following year, replacing AOL founder Steve Case, who had also championed the combination. The newly formed company’s Internet division quickly became a drag on Time Warner. The promised synergies between traditional and new media never materialized. AOL began seeing a reduction in subscribers in 2002 as Americans replaced dial-up connections with broadband from cable TV and phone companies. Parsons stepped down as CEO in 2007 and as chairman in 2008. A year later AOL split from Time Warner and began trading as a separate company, following years of struggles to reinvent itself as a business focused on advertising and content. Time Warner is now owned by AT&T Inc. A board member of Citigroup and its predecessor, Citibank, since 1996, Parsons was named chairman in 2009 at a time of turmoil for the financial institution. Citigroup had suffered five straight quarters of losses and received $45 billion in government aid. Its board had been criticized for allowing the bank to invest so heavily in the risky housing market. Citigroup returned to profit under Parsons, starting in 2010, and would not have a quarterly loss again until the fourth quarter of 2017. Parsons retired from that job in 2012. In 2014 he stepped in as interim CEO of the Clippers until Microsoft CEO Steve Ballmer took over later that year. Parsons, a Republican, previously worked as a lawyer for Nelson Rockefeller, a former Republican governor of New York, and in Gerald Ford’s White House. Those early stints gave him grounding in politics and negotiations. He also was an economic adviser on President Barack Obama’s transition team. Parsons, who loved jazz and co-owned a Harlem jazz club, also served as Chairman of the Apollo Theater and the Jazz Foundation of America. And he held positions on the boards of the Smithsonian National Museum of African American History and Culture, the American Museum of Natural History and the Museum of Modern Art in New York City. Parsons played basketball at the University of Hawaii at Manoa and received his law degree from Albany Law School in 1971. He is survived by his wife, Laura, and their family.

MAPUTO, Mozambique. (AP) — At least 6,000 inmates escaped from a high-security prison in Mozambique’s capital on Christmas Day after a rebellion, the country's police chief said, as widespread post-election riots and violence are roiling the country. Police chief Bernardino Rafael said 33 prisoners died and 15 others were injured during a confrontation with the security forces. The prisoners fled during violent protests that have seen police cars, stations and infrastructure destroyed after the country’s Constitutional Council confirmed the ruling Frelimo party as the winner of the Oct. 9 elections. The escape from the Maputo Central Prison, located 14 kilometers (9 miles) southwest of the capital, started around midday on Wednesday after “agitation” by a “group of subversive protesters” nearby, Rafael said. Some of the prisoners at the facility snatched weapons from the guards and started freeing other detainees. “A curious fact is that in that prison we had 29 convicted terrorists, who they released. We are worried, as a country, as Mozambicans, as members of the defense and security forces,” said Rafael. “They (protesters) were making noise, demanding that they be able to remove the prisoners who are there serving their sentences”, said Rafael, adding that the protests led to the collapse of a wall, allowing the prisoners to flee. He called on the escaped prisoners to surrender to authorities and for the population to be informed about the fugitives. Videos circulating on social media show the moment inmates left the prison, while other recordings reveal captures made by military personnel and prison guards. Many prisoners tried to hide in homes, but some were unsuccessful and ended up being detained again. In one video, a prisoner still with handcuffs on his right wrist says he was held n the disciplinary section of the prison and was released by other inmates. Violence has engulfed Mozambique since the country’s highest court confirmed ruling Frelimo party presidential candidate Daniel Chapo as the winner of disputed Oct. 9 elections on Monday. Mozambique's Interior Minister Pascoal Ronda told a news conference in Maputo late Tuesday that the violence was led by mostly youthful supporters of losing candidate Venancio Mondlane, who received 24% of the vote, second to Chapo, who got 65%. U.N. Secretary-General Antonio Guterres is concerned at the violence and urges all political leaders and relevant parties “to defuse tensions including through meaningful dialogue (and) legal redress,” U.N. associate spokesperson Stephanie Tremblay said Thursday. The U.N. chief also calls for a halt to the violence and redoubled efforts “to seek a peaceful resolution to the ongoing crisis,” she said.Building a gaming PC is too expensive, and GPUs really aren't helping
NEW DELHI (AP) — India’s former Prime Minister Manmohan Singh, widely regarded as the architect of India’s economic reform program and a landmark nuclear deal with the United States, has died. He was 92. Singh was admitted to New Delhi’s All India Institute of Medical Sciences late Thursday after his health deteriorated due to a “sudden loss of consciousness at home,” the hospital said in a statement. “Resuscitative measures were started immediately at home. He was brought to the Medical Emergency” at 8:06 p.m., the hospital said, but “despite all efforts, he could not be revived and was declared dead at 9:51 p.m.” Singh was being treated for “age-related medical conditions,” the statement said. A mild-mannered technocrat, Singh became one of India’s longest-serving prime ministers for 10 years and leader of the Congress Party in the Parliament's Upper House, earning a reputation as a man of great personal integrity. He was chosen to fill the role in 2004 by Sonia Gandhi, the widow of assassinated Prime Minister Rajiv Gandhi . But his sterling image was tainted by allegations of corruption against his ministers. Singh was reelected in 2009, but his second term as prime minister was clouded by financial scandals and corruption charges over the organization of the 2010 Commonwealth Games. This led to the Congress Party’s crushing defeat in the 2014 national election by the Hindu nationalist Bharatiya Janata Party under the leadership of Narendra Modi . Singh adopted a low profile after relinquishing the post of prime minister. Prime Minister Modi, who succeeded Singh in 2014, called him one of India’s “most distinguished leaders” who rose from humble origins and left “a strong imprint on our economic policy over the years.” “As our Prime Minister, he made extensive efforts to improve people’s lives,” Modi said in a post on the social platform X. He called Singh’s interventions in Parliament as a lawmaker “insightful” and said “his wisdom and humility were always visible.” Rahul Gandhi, from the same party as Singh and the opposition leader in the lower house of the Indian Parliament, said Singh’s “deep understanding of economics inspired the nation” and that he “led India with immense wisdom and integrity.” “I have lost a mentor and guide. Millions of us who admired him will remember him with the utmost pride,” Gandhi wrote on X. The United States offered its condolences, with Secretary of State Antony Blinken saying that Singh was “one of the greatest champions of the U.S.-India strategic partnership.” “We mourn Dr. Singh’s passing and will always remember his dedication to bringing the United States and India closer together,” Blinken said. Born on Sept. 26, 1932, in a village in the Punjab province of undivided India, Singh’s brilliant academic career took him to Cambridge University in Britain, where he earned a degree in economics in 1957. He then got his doctorate in economics from Nuffield College at Oxford University in 1962. Singh taught at Panjab University and the prestigious Delhi School of Economics before joining the Indian government in 1971 as economic advisor in the Commerce Ministry. In 1982, he became chief economic adviser to the Finance Ministry. He also served as deputy chair of the Planning Commission and governor of the Reserve Bank of India. As finance minister, Singh in 1991 instituted reforms that opened up the economy and moved India away from a socialist-patterned economy and toward a capitalist model in the face of a huge balance of payments deficit, skirting a potential economic crisis. His accolades include the 1987 Padma Vibhushan Award, India’s second-highest civilian honor; the Jawaharlal Nehru Birth Centenary Award of the Indian Science Congress in 1995; and the Asia Money Award for Finance Minister of the Year in 1993 and 1994. Singh was a member of India’s Upper House of Parliament and was leader of the opposition from 1998 to 2004 before he was named prime minister. He was the first Sikh to hold the country’s top post and made a public apology in Parliament for the 1984 Sikh Massacre in which some 3,000 Sikhs were killed after then-Prime Minister Indira Gandhi was assassinated by Sikh bodyguards. Under Singh, India adopted a Right to Information Act in 2005 to promote accountability and transparency from government officials and bureaucrats. He was also instrumental in implementing a welfare scheme that guaranteed at least 100 paid workdays for Indian rural citizens. The coalition government he headed for a decade brought together politicians and parties with differing ideologies that were rivals in the country’s various states. In a move hailed as one of his biggest achievements apart from economic reforms, Singh ended India’s nuclear isolation by signing a deal with the U.S. that gave India access to American nuclear technology. But the deal hit his government adversely, with Communist allies withdrawing support and criticism of the agreement growing within India in 2008 when it was finalized. Singh adopted a pragmatic foreign policy approach, pursuing a peace process with nuclear rival and neighbor Pakistan. But his efforts suffered a major setback after Pakistani militants carried out a massive gun and bomb attack in Mumbai in November 2008. He also tried to end the border dispute with China, brokering a deal to reopen the Nathu La pass into Tibet, which had been closed for more than 40 years. His 1965 book, “India’s Export Trends and Prospects for Self-Sustained Growth,” dealt with India’s inward-oriented trade policy. Singh is survived by his wife Gursharan Kaur and three daughters. Associated Press writer Sheikh Saaliq in New Delhi contributed to this report.ROHM Semiconductor and Valeo Co-Develop the Next Generation of Power ElectronicsRichard Parsons, prominent Black executive who led Time Warner and Citigroup, dies at 76Home | Malema speaks against infiltration of the EFF, takes jab at Zuma EFF leader Julius Malema has likened the party’s mass exodus by some of its prominent senior members to an assassination attempt. His comments come as prominent figures like Floyd Shivambu, Dali Mpofu, Mzwanele Manyi and Busisiwe Mkhwebane have deserted the party to join uMkhonto weSizwe led by Jacob Zuma. Malema was speaking at the EFF’s Gauteng Provincial General Assembly held in Benoni, Gauteng today ahead of the party’s third national people’s assembly next month. “Perhaps we must be thankful that the path to desert us was chosen instead. Perhaps we must be thankful that we did not die. But we must register today and for future generations to remember that the deserting of the EFF at this critical moment in our liberation struggle constitutes an assassination attempt. It is time for important fighters to not individualise even (during) this moment of infiltration and betrayal of the EFF,” says Malema. Malema has taken jabs at uMkhonto weSizwe leader, Jacob Zuma, saying that the party will not sell the future generation for the former ANC President’s dreams. EFF | Malema talks tough ahead of 3rd National People’s Assembly: Malema’s comments come after his revelation that former EFF Chairperson Adv Dali Mpofu proposed that the EFF must be dissolved to join the MK Party. The EFF leader says that Zuma has failed to unite black progressive forces. “So, how do you say you can unite people when you are 82 years old? We have been failing to unite them for the past 82 years. You think you can do it now? The unity you are talking about is not a lip service. It’s not something used to mobilize people for the sake of positions. We need this unity of Africans in practical terms. That’s why we are the only organisation that has got EFF Nigeria, EFF Ghana, EFF Nigeria,” says Malema. Next month, the EFF will host its national people’s assembly at Nasrec, where a new leadership will be elected. SABC © 2024
