Today is Nelson Mandela International Day, and Ban Ki-moon, Secretary-General of the United Nations, released this message.“Last year, the world lost one of its greatest leaders when Nelson Mandela passed away. We remember his legacy especially on his birthday, the 18th of July.“Nelson Mandela and the United Nations had a strong history together. Shortly after he was released from prison, he came to our Headquarters. It was a moment of great excitement.“Nelson Mandela’s presence in the General Assembly Hall proved that United Nations resolutions, sanctions and solidarity can win over violence and injustice. His extraordinary compassion after 27 years in prison showed that human rights and equality are stronger than discrimination and hate. On that day in 1990, he said people would always be challenged by the fact that, quote, “it took as long as it has before all of us stood up to say enough is enough”. The room burst into applause.“Apartheid is gone – thanks to Nelson Mandela, countless other individuals and the proud actions of the United Nations. But our planet and its people still face terrible threats — poverty, discrimination, climate change, conflict and more. Nelson Mandela Day is a call to action. Each of us can celebrate this day by helping to address real problems in our communities. Together we can give great meaning to our celebration by paving the way for a better future.”
Lance Armstrong plans to admit to doping throughout his career during an upcoming interview with talk show host Oprah Winfrey, USA Today reported late Friday.The interview, scheduled to be taped Monday and broadcast Thursday night on the Oprah Winfrey Network, will be conducted at Armstrong’s home in Austin, Texas.Citing an anonymous source, USA Today reported that the disgraced cyclist plans to admit to using performance-enhancing drugs, but likely will not get into details of the allegations outlined in a 2012 report by the U.S. Anti-Doping Agency. The report led to Armstrong being stripped of his seven Tour de France titles and banned for life from the sport.Armstrong representatives, including his attorney Tim Herman, declined comment. The New York Times first reported last week that Armstrong was considering making a confession.Armstrong, 41, who vehemently denied doping for years, has not spoken publicly about the USADA report that cast him as the leader of a sophisticated and brazen doping program on his U.S. Postal Service teams that included use of steroids, blood boosters and illegal blood transfusions.Winfrey’s network announced Tuesday that Armstrong agreed to a “no holds barred” interview with her.A confession to Winfrey would come at a time when some of Armstrong’s legal troubles appear to be clearing up.Any potential perjury charges stemming from his sworn testimony denying doping in a 2005 arbitration fight with a Dallas promotions company over a contract bonus worth $7.5 million have passed the statute of limitations.Armstrong faces a whistle-blower lawsuit filed by former teammate Floyd Landis accusing him of defrauding the U.S. Postal Service, but the U.S. Department of Justice has yet to announce whether it will join the case. The British newspaper The Sunday Times is suing Armstrong to recover about $500,000 it paid him to settle a libel lawsuit.Armstrong lost most of his personal sponsorship — worth tens of millions of dollars — after USADA issued its report, and he left the board of the Livestrong cancer-fighting charity he founded in 1997. He is said to still be worth an estimated $100 million.Livestrong might be one reason to issue an apology or make a confession. The charity supports cancer patients and faces an image problem because of its association with its famous founder.The New York Times reported Armstrong might make a confession in an attempt to return to competition in elite triathlon or running events, but World Anti-Doping Code rules state his lifetime ban cannot be reduced to less than eight years. WADA and U.S. Anti-Doping officials could agree to reduce the ban further depending on what new information Armstrong provides and his level of cooperation.Armstrong met with USADA officials recently to explore a “pathway to redemption,” according to a report by “60 Minutes Sports” aired Wednesday on Showtime.
TIger Woods put on another masterful putting display Friday, helping him shoot a 65 and earn a two-shot lead going into the weekend in the WGC-Cadillac Championship at Doral.Woods, who has won three times at Doral and has captured this World Golf Championship event six times, gave himself numerous chances with a solid ballstriking round in which he barely missed a green.His 7-under 65 gave him a two-shot lead over 2010 U.S. Open champion Graem McDowell and a three-shot lead over Phil Mickelson and Steve Stricker, his buddy who gave him putting tips that Woods attributes to his solid play with the flat stick so far.Woods has won 26 -of-31 times when he has the outright 36-hole lead in his PGA Tour career.On Wednesday, Stricker gave Woods some advice during a 45-minute session on the practice green, one that has led to two days of exceptional work.“I’ve always liked the way he putts it,” Stricker said. “We’ve talked a lot about it over the years. We have the same ideas, although we do different things to get it there. We have the same principles. He’s open to hearing what I have to say sometimes.”This time, it worked, as Woods made nine birdies Thursday and added eight more Friday. He has had 22 one-putt greens in the tournament, and on Friday he hit 15-of-18 greens in regulation.For a time, it appeared Mickelson would play his way into a third-round pairing with Woods, reprising their epic 2005 final-round duel here in which Woods prevailed by a stroke to regain the No. 1 world ranking.But McDowell had other ideas, birdieing his last two holes for a 67.“I saw Phil sneaking up the leaderboard there behind me, and I said to (caddie) Kenny (Comboy), ‘Let’s spoil this party tomorrow,’ ” McDowell said. “I’m sure they would have liked Tiger and Phil in the last group tomorrow, would have been great for the tournament, but I certainly will enjoy the position of being in the last group and the mix. That’s right where I want to be.“Great to see the best players in the game playing as well as they are. Always exciting to have Tiger and Phil playing well. It brings the crowds and puts people behind their TV screens, and that’s what’s important.”Mickelson has shot 67-67 after an early-week visit to Augusta National to scout the Masters venue.“I saw Tiger was playing well and I wanted to make a couple birdies to get in the group with him,” Mickelson said. “It seems since 2007, when we played at Deutsche Bank in Boston, I’ve been playing some of my best golf when we get paired together.“I hope that tomorrow that I play a good round and so does he, and we get a chance to get paired together in Sunday’s final round, because he seems to somehow bring out my best golf.”

The JMB and National Commercial Bank have signed a syndicated loan agreement with 138 Student Living Jamaica Ltd, the developers and proposed operator of the new residences, for the first phase, with JMB taking on the role of lead bank.A syndicated loan is one that is offered by a group of lenders (called a syndicate) who work together to provide funds for a single borrower.General Manager of JMB, Courtney Wynter, said the project can contribute to economic progress through investment in education, and housing development and construction, which are key drivers of growth. “Our analysis shows that for every $250 million that is spent by the housing sector the Government benefits by earning about $103 million, which is just about 40 per cent”, he noted.Mr. Wynter pointed out that the public-private partnership for student accommodation is the first of its kind in Jamaica.“The JMB is excited to be leading this innovative approach to financing. The project will have a tremendous impact on education and training as it supports the university’s strategic drive to increase enrolment, particularly in the areas of medicine, law and engineering,” he added.The housing development involves the construction of 11 six-storey buildings and will be configured to allow access for the disabled.The construction period is 36 to 48 months and should be completed in three segments at the beginning of the 2015, 2016, and 2017 academic years.

Journal information: Nature Chemistry (Phys.org)—Molecules are rarely found alone. In the real world, they are often networked to each other through hydrogen bonding or are bound to other molecules in the surrounding environment. One way to study an individual molecule is to trap it within a fullerene. A fullerene is an all-carbon, spherical molecule with carbons networked like the stitches of a soccer ball. The interior of the fullerene sphere is large enough to house small molecules, such as water or hydrogen gas. More information: Andrea Krachmalnicoff et al. The dipolar endofullerene HF@C60, Nature Chemistry (2016). DOI: 10.1038/nchem.2563AbstractThe cavity inside fullerenes provides a unique environment for the study of isolated atoms and molecules. We report the encapsulation of hydrogen fluoride inside C60 using molecular surgery to give the endohedral fullerene HF@C60. The key synthetic step is the closure of the open fullerene cage with the escape of HF minimized. The encapsulated HF molecule moves freely inside the cage and exhibits quantization of its translational and rotational degrees of freedom, as revealed by inelastic neutron scattering and infrared spectroscopy. The rotational and vibrational constants of the encapsulated HF molecules were found to be redshifted relative to free HF. The NMR spectra display a large 1H–19F J coupling typical of an isolated species. The dipole moment of HF@C60 was estimated from the temperature dependence of the dielectric constant at cryogenic temperatures and showed that the cage shields around 75% of the HF dipole.

In a recent study, Andrea Krachmalnicoff, et al. from the University of Southampton, the University of Nottingham, and Institutions in France and Estonia have trapped hydrogen fluoride in the cavity of a C60 fullerene (HF@C60). Their characterization studies reveal that HF breaks the fullerene’s icosahedral symmetry and that the fullerene cage serves to shield the strongly polar molecule. Their work appears in Nature Chemistry.Researchers have been able to trap molecules within the fullerene cavity using a process called “molecular surgery.” As the name implies, the fullerene molecules is chemically “cut open” and a small molecule is forced into the spherical cavity. The hole is then chemically “sutured.”Previous research by this group demonstrated the successful encapsulation of HF in an open-cage fullerene; however attempts to suture the open-cage resulted in the HF molecule escaping. The current study reports the successful encapsulation of HF by reacting their open-cage product with PPh(Fu)2 ([2-furanyl] phenylphosphine] in the presence of molecular sieves at room temperature. They obtained the pre-cursor product that can be sutured using methods employed in the synthesis H2O@C60 (i.e., reduction with triisopropylphosphite followed by reaction with N-phenyl-maleimide).X-ray studies of HF@C60 indicated some distortion of the fullerene cage but because the distortions were not outside of standard deviation values, the results were inconclusive. UV and electrochemical studies, however, did show that the HF molecule does not seem to show an electrostatic interaction with the C60 cage.NMR studies using 1H, 13C, and 19F NMR as well as solid state 1H and 13C NMR provided more compelling information on the behavior of HF. The J coupling for 1H-19F confirm that there is a single molecule of HF within the C60 cavity.Krachmalnicoff, et al. then used inelastic neutron scattering and infrared absorption at low temperature to gain insight into the molecule’s intrinsic properties. Their findings provide evidence that HF’s rotational, vibrational, and translational motion is quantized with all transitions originating from the ground state. These studies showed that in the solid state, HF interact with the C60 molecule both by breaking its icosahedral symmetry and through dipole interactions with the interior of the cage.Hydrogen fluoride has a large dipole moment. Using capacitance studies to find the dielectric constant at low temperatures, Krachmalnicoff, et al. found that C60 shields the dipole such that the dipole moment for encapsulated HF is about 25% of the calculated dipole moment for HF.Overall, this research provides some interesting information on the properties of a single-molecule HF. Additional studies are needed to investigate why HF@C60 breaks the endofullerene’s icosahedral symmetry in the solid state as well as further investigation into HF@C60’s electronic properties.
