(AP Photo/Richard W. Rodriguez)FRISCO, Texas — Errol Spence Jr. gave the home folks the knockout he figured they wanted. There just wasn’t much of the show he hoped would go with it.Spence stopped Carlos Ocampo to retain his IBF welterweight title, dropping the Mexican challenger with a right hand to the body as the first round was ending Saturday night.ADVERTISEMENT MOST READ Ocampo (22-1) was fighting professionally outside his home country for the first time.“l got a lot of experience out of fighting Errol,” Ocampo said. “It would have been a very difficult fight for me. I got overconfident at the end of the round and he caught me.”The buildup for the right was all the crowd got, with Spence taking the ring to big cheers with a big Cowboys star logo on the front of his robe. Earlier, Spence got a good roar when he was shown on camera alongside Jones near his locker room.“This moment is a dream,” Spence said. “I wanted to play for the Dallas Cowboys and now I’m fighting in front of the Dallas Cowboys and Jerry Jones.”Spence battered Lamont Peterson in his first title defense in New York in January, winning in the eighth round. Last summer in Sheffield, England, Spence broke Brook’s orbital bone and knocked him down in the 10th round before the fight was stopped in the 11th.This was Spence’s first fight as a co-promoter, the other reason besides the hometown crowd that the show was part of the story line.“We’ll definitely be back after I unify some titles,” Spence said. “We’ll make this an annual thing where I fight here.”Spence’s victory came a week after Terence Crawford took the WBO crown from Jeff Horn, who had beaten Manny Pacquiao a year earlier. But Spence’s focus is on the expected August fight between Danny Garcia and Shawn Porter for the WBC title.“I definitely want to make that a unifying fight,” Spence said. “We both have the same management. Why not make that happen? I definitely want that fight whenever it’s available.”In the previous fight, WBA super bantamweight champion Danny Roman won a unanimous decision over Moises Flores. Roman would have retained the belt regardless of the outcome because Flores didn’t make weight. “I went for the body because we knew he was so drained from cutting weight,” Roman said. “Him missing weight and not being able to win my belt didn’t change anything.”A 10-round junior welterweight fight between Javier Fortuna and Adrian Granados ended in a no-decision after Fortuna appeared to hit his head while falling backward out of the ring during the fourth round. Fortuna was placed in a neck brace and taken away on a stretcher.The 28-year-old Fortuna went to a hospital and was diagnosed with a concussion.“I didn’t push him,” Granados said. “I think he was looking for an excuse on his way out. We were both battling, but I knew he could feel I was getting stronger. Let’s do the rematch.” Carpio hits red carpet treatment for China Coast Guard PLAY LIST 02:14Carpio hits red carpet treatment for China Coast Guard02:56NCRPO pledges to donate P3.5 million to victims of Taal eruption00:56Heavy rain brings some relief in Australia02:37Calm moments allow Taal folks some respite03:23Negosyo sa Tagaytay City, bagsak sa pag-aalboroto ng Bulkang Taal01:13Christian Standhardinger wins PBA Best Player award Fighting at the Dallas Cowboys’ practice facility after growing up in the suburbs as a fan of America’s Team, Spence improved to 24-0 with his 11th straight knockout and 21st overall.The crowd might have been left wanting more, as Cowboys owner Jerry Jones jokingly suggested after winking at the camera while celebrating with the 2012 U.S. Olympian in the ring.FEATURED STORIESSPORTSGinebra beats Meralco again to capture PBA Governors’ Cup titleSPORTSAfter winning title, time for LA Tenorio to give back to Batangas folkSPORTSTim Cone, Ginebra set their sights on elusive All-Filipino crown“He can fight again tonight if someone wants to step up and fight him,” Jones said.Ocampo crumpled to the canvas after taking the body shot.

I wanted him to sustain a bit and give him some punishment, but the body shot got him and I dropped him.”The 28-year-old Spence was fighting in front of a sellout crowd in the 12,000-seat football stadium that doubles as the indoor practice facility for the Cowboys at their headquarters about 30 miles north of Dallas.Cowboys quarterback Dak Prescott and several teammates were in the crowd along with Jones.“This room was full of Dallas Cowboys football players supporting you,” Jones said. “They share your passion. I saw a guy in this ring who knew what he wanted. When you knock a guy out by hitting him once on the side of his back, you’re bad to the bone.”It was the second defense of the 147-pound title that Spence won last summer in Englishman Kell Brook’s hometown.ADVERTISEMENTlast_img read more

Mike Trout Is The MVP — And Still On Track For The

PLAYERWAR Los Angeles Angels outfielder Mike Trout is widely acknowledged to be the best player in baseball and has been for quite some time. But for all his gifts, awards recognition has been hard for Trout to come by. Although Trout has led the American League in wins above replacement (WAR) for each of the past five seasons,1Ever since he first became a full-time player in 2012. he had only won MVP honors once going into Thursday night’s award announcement — and victory there was far from assured.Unlike in the past, though, when Trout’s horrid teammates were held against him in favor of some lesser player on a winning team, the voters broke with tradition and went for the player with stellar individual numbers. In winning the MVP, Trout became just the sixth player from a losing team to take home the hardware. It was a victory for the new ways of player evaluation and a more modern take on what the “valuable” part of MVP really means.But even if Trout hadn’t won the award, he could have taken the same solace he could last year: MVP or not, but he’s still tracking to be the G.O.A.T.Through every single age in which he played a full season,2Not including his age-19 season in 2011, when he logged only 40 games after a July call-up. Trout has been the all-time career leader in Baseball-Reference.com’s WAR for position players. It was true through age 20, age 21, age 22, age 23 and — after posting 10.6 WAR in 2016, a performance that basically matched his previous single-season peak — age 24. No player has ever started his career on this kind of tear — not Ruth, not Cobb, not Mantle, nobody. PLAYERWAR 5Ken Griffey Jr.37.0 Most career WAR through each age since 1901, among position players.Source: Baseball-Reference.com 2Mel Ott11.42Mel Ott17.9 5Al Kaline8.95Al Kaline15.4 WAR Through Age 24 Mike Trout is (still!) the G.O.A.T. at any age 2Ty Cobb25.52Ty Cobb36.0 As a result — and in concert with MLB labor mechanisms that force young stars to either play for peanuts through their arbitration years or lock themselves into long, below-market extensions (as Trout did in 2014, re-signing with the Angels through 2020) — Trout has produced a ton of surplus value for the Angels, relative to what he’s been paid. According to FanGraphs.com, Trout’s production would have been worth about $357 million on the open market since his MLB debut, a span over which he was paid only about $24 million.That’s why speculation that the Yankees are loading up for a Trout trade breaks down upon examination. At a glance, why not ship Trout away from a rebuilding team where his WAR is being wasted (aside, of course, from Angels fans who like to watch him play) to a huge market that has the prospects for a blockbuster deal? The answer: It would take a monster package of young talent to justify trading away a player who so outperforms his contract and probably will continue to do so for the next several years.If we apply Tom Tango’s simple WAR projection system with an average future value of $8.6 million per win,3Starting with a rough cost-estimate of $8 million per WAR next season, with 5 percent annual growth until 2020. the final four seasons of Trout’s contract figure to see him generate 32.5 WAR, for a market value of $282 million,4Including the yearly minimum salary of about $500,000. and be paid $122 million. So it probably won’t be until Trout’s next contract that the cost-benefit tradeoff of having him around begins to make a trade realistic for either the Angels or the team they’re negotiating with.At that point, the math gets a little silly. Even in the first year of his next deal, Trout’s WAR projects to be worth so much on the open market (roughly $75 million) that he’d need a truly paradigm-shifting contract — one that would basically double the highest annual salary of anybody in the game right now — to not be underpaid. With superstar free-agent deals, the question often isn’t whether they’ll be paid more than they’re worth, but by how much. Trout, however, is so good that it might be hard for him to earn fair market value even in his big post-prime payday.For now, that means Trout is probably stuck carrying the Angels. In the past, that would have also meant his chances of contending for the MVP were slim, despite his incredible individual numbers. But perhaps Trout’s win Thursday also signals a change in the way voting will be conducted going forward. The MVP electorate has been skewing more progressive for a while, in terms of its willingness to use sabermetric tools, and there’s nothing more open-minded than giving the MVP to the leader of a 74-88 team.But maybe it was also about Trout’s own particular greatness. No player has ever been so good at such a young age; it was likely that future generations would have looked at his repeated MVP snubs and wondered what the hell the voters were thinking to deny him the AL’s top individual award, over and over. 4Mel Ott23.54Mel Ott31.4 1Mike Trout48.5 WAR Through Age 20WAR Through Age 21 a 3Ty Cobb9.53Ty Cobb15.7 1Mike Trout28.61Mike Trout37.9 5Alex Rodriguez22.95Ken Griffey Jr.30.1 3Mickey Mantle40.9 2Ty Cobb46.7 1Mike Trout11.41Mike Trout20.7 WAR Through Age 22WAR Through Age 23 3Ted Williams23.63Ted Williams34.2 a 4Bryce Harper8.94Ken Griffey Jr.15.5 4Alex Rodriguez38.0 read more

Continuous breathing metalorganic framework with guest selectivity

first_img More information: Elliot J. Carrington et al. Solvent-switchable continuous-breathing behaviour in a diamondoid metal–organic framework and its influence on CO2 versus CH4 selectivity, Nature Chemistry (2017). DOI: 10.1038/nchem.2747AbstractUnderstanding the behaviour of flexible metal–organic frameworks (MOFs)—porous crystalline materials that undergo a structural change upon exposure to an external stimulus—underpins their design as responsive materials for specific applications, such as gas separation, molecular sensing, catalysis and drug delivery. Reversible transformations of a MOF between open- and closed-pore forms—a behaviour known as ‘breathing’—typically occur through well-defined crystallographic transitions. By contrast, continuous breathing is rare, and detailed characterization has remained very limited. Here we report a continuous-breathing mechanism that was studied by single-crystal diffraction in a MOF with a diamondoid network, (Me2NH2)[In(ABDC)2] (ABDC, 2-aminobenzene-1,4-dicarboxylate). Desolvation of the MOF in two different solvents leads to two polymorphic activated forms with very different pore openings, markedly different gas-adsorption capacities and different CO2 versus CH4 selectivities. Partial desolvation introduces a gating pressure associated with CO2 adsorption, which shows that the framework can also undergo a combination of stepped and continuous breathing. Proposed role of guest–framework interactions in the solvent-dependent continuous-breathing properties of SHF-61. Credit: (c) Nature Chemistry (2017). DOI: 10.1038/nchem.2747 After heating SHF-61-CHCl3 to remove solvent, it exhibited type I adsorption isotherm behavior for N2 and CO2. This was as expected from previous studies. What was new for this study, though, was that CH4 also followed type I adsorption isotherm, but it took much longer for adsorption to occur. This kinetic difference allows for selective adsorption, which has implications for practical uses such as catalysis and separation techniques.Typically studies with MOFs are either all or nothing in the sense that the adsorption measurements are taken after complete desolvation of the MOF to determine total guest uptake. SHF-61 was also studied for gas adsorption as a partially desolvated MOF, which is the first of this kind of study. The partially desolvated SHF-61-DMF showed a stair-step isotherm instead of type I adsorption isotherm typical of an approximately fixed pore size. The mechanism at work here was identified by in situ powder x-ray diffraction and has to do with a sudden opening of the pores at a particular CO2 pressure threshold.Finally, while cation-framework interactions are difficult to study, crystallographic studies show that guest-framework and cation-framework interactions control the breathing mechanism, particularly whether the guest is able to overcome cation-framework interactions. This explains the stair-step adsorption pattern for the partially desolvated MOF. While adsorption of CO2 is at first slow, once the pressure of CO2 is high enough to overcome cation-framework interactions, then the pores open allowing for more CO2 to adsorb.This research demonstrates a unique continuous breathing MOF whose properties have allowed for unprecedented studies in the SHF-61’s mechanism and guest selectivity. This research has implications for molecular sensing for gas separation. Because the authors were able to gain new insights into continuous breathing MOFs, future research may include developing other continuous breathing MOFs.

The content is provided for information purposes only. © 2017 Phys.org Explore further (Phys.org)—Researchers from the University of Sheffield report a new continuous-breathing metal-organic framework (MOF), SHF-61, that has two different solvent-specific forms, a narrow-pore structure that is the result of DMF or H2O desolvation and a wide-pore structure that is the result of CHCl3 desolvation. The wide-pore form showed uptake of N2, CO2, and CH4 with selectivity for CO2. They were also able to conduct single-crystal structure analysis of their MOF during breathing motions. Their work appears in Nature Chemistry. “Being modular in construction allows MOFs to be tailored for a wide variety of applications that exploit their molecular-scale porosity. Highly flexible MOFs remain uncommon, but offer the possibility of developing guest-responsive materials. Identifying new flexible MOFs may open many doors for applications, particularly in selective entrapment and release, separation and sensing of molecules,” explains Lee Brammer, who is Professor of Inorganic and Solid State Chemistry at the University of Sheffield. “The flexible behavior of SHF-61 is quite complicated, but what helped in this case is that it proved feasible to study the structural changes in some detail by single-crystal X-ray diffraction.”Breathing MOFs, are metal-organic frameworks whose structure reversibly changes upon some kind of external stimulus. Very few MOFs have been reported to display breathing behavior and of the known MOFs, most undergo some kind of structural change due to a crystal phase transition. This structural change leads to a difference in pore size, which, in turn, allows for the reversible adsorption and desorption of guests. Because these MOFs undergo a phase change, their adsorption profiles (i.e., adsorption isotherms) look like stair steps.What is not common among breathing MOFs is continuous rather than a stair-step adsorption profile. Continuous breathing MOFs, such as MIL-88, have proven difficult to isolate and study. This paper reports single-crystal and powder XRD studies of continuous-breathing MOF SHF-61.SHF-61, or (Me2NH2)[In(ABDC)2], where ABDC is 2-aminobenzene-1,4-dicarboxylate, has an In(III) metal coordinated to carboxylates that serve as hinges for the continuous breathing mechanism. The authors point out that the hinge is from rotation of the ABDC ligands around the O—-O of the carboxylates. This is accompanied by changes in the coordination geometry around In(III). The combination of the two motions enables the continuous breathing.Specifically, In(III) is chelated to four ABDC ligands providing a flattened tetrahedral geometry around the metal center. The resulting anionic framework has diamond-shaped pores, which contain dimethylammonium cations that balance the charge. The pore size is largely dependent on the solvent. Carrington et al. isolated solvated forms of the MOF, SHF-61-DMF and SHF-61-CHCl3, and demonstrated how removal of each solvent affects pore size, and therefore guest uptake, differently. Removal of the more strongly interacting DMF leads to narrowing of the pores whereas removal of the more weakly interacting CHCl3 leaves the pores fully open.
