The fire started in one container aboard the ship and spread to additional containers.Efforts to extinguish the fire were launched on the same day but they were hampered by bad weather conditions.During the weekend, the ship’s crew members were evacuated to the tugboat Smit Nicobar after the fire increased in intensity.The USCG said the tugboat remained on scene, providing firefighting assistance.“We’ve been monitoring the situation to provide as much assistance as possible and keeping in open communication,” Chief Petty Officer Ryan Langley, operations unit watchstander at the Fifth District command center, said.
New Delhi: Marginal 2.44 per cent increase in exports as well as lower imports of gold and petroleum products in February significantly narrowed the country’s trade deficit to $9.6 billion, according to data released by the commerce ministry Friday. India’s merchandise exports rose to $26.67 billion in February from $26.03 per cent in the year-ago month mainly on account of higher shipments in sectors such as pharmaceutical, engineering and electronics. Also Read – Ensure strict implementation on ban of import of e-cigarettes: revenue to CustomsImports declined by 5.4 per cent to $36.26 billion in the last month, narrowing the trade deficit to $9.6 billion. The gap between imports and exports was $12.3 billion in February 2018, and $14.73 billion in January 2019. As per the data, the decline in imports was mainly on account of sharp decline in inward shipments of gold and petroleum products. While the import of gold fell by about 11 per cent to $2.58 billion in February as against $2.89 billion in the corresponding month last fiscal, inward shipments of petroleum products were down by nearly 8 per cent to $9.37 billion. Also Read – Coking coal shipments rise 15 pc to 29 MT at 12 state-run ports in Apr-SepDuring the April-February period of the current fiscal year, exports grew 8.85 per cent to $298.47 billion, while imports rose by 9.75 per cent to $464 billion. The trade deficit has widened to $165.52 billion during the 11 months of the current fiscal from $148.55 billion compared to the year-ago period, the data said. Non-petroleum and non-gems and jewellery exports in February 2019 stood at $19.87 billion, as compared to $18.90 billion in year-ago month. Non-petroleum and non-gems and jewellery exports in April-February 2018-19 were $217.43 billion, as against $201.95 billion in the comparative period last fiscal. Oil imports in April-February 2018-19 were $128.72 billion, which was 31.98 per cent higher over the same period last fiscal. The global Brent price (USD/bbl) decreased by 1.97 per cent in February 2019 compared to the same month previous year. Commenting on the trade data, President of exporters’ body FIEO Ganesh Kumar Gupta said that exporters have managed to do well despite increasing protectionism, tough global conditions and constraints on the domestic front. He said economies across Asia specially China and South East Asian nations have been showing signs of sluggishness with contraction in manufacturing due to slowdown in the global trade and fragile world economy. Gupta said 18 out of 30 major product groups were in positive territory, with most of them with marginal growth during the month. “However, with this trend, we will be able to achieve merchandise exports of about $330 billion, the highest ever exports for a fiscal,” he added. Meanwhile, the RBI said services exports in January 2019 were $17.75 billion, registering a negative growth of 1.02 per cent over December 2018. The imports stood at $11.03 billion, down 3.07 per cent over December 2018. Taking merchandise and services together, overall trade deficit for April-February 2018-19 is estimated at $93.32 billion as compared to $82.46 billion in year-ago period.

Wayanad/Alathur: Launching a blistering attack on Narendra Modi, Congress Chief Rahul Gandhi said all that the Prime Minister “does is tell lies and steal from the poor people.”Gandhi, who addressed three election rallies in his Wayanad Lok Sabha constituency, spread over the districts of Wayanad, Malappuram and Kozhikode and campaigned in Thirthala in Palakkad district, attacked Modi and RSS and touched on corruption. “All the PM does is tell lies and steal from the poor people.

Fifty lakh people lost their jobs after demonetisation,” the Congress chief said while winding off his campaign at Thrithala this evening. All praise for Wayanad, the second constituency from where Gandhi is contesting for which he was attacked by Modi and BJP, Gandhi said he wanted to represent the remote district as the “beautiful place” symbolises different ideas and cultures.

Gandhi also said the saffron party was arrogant and believed that they can re-define Indian history. “Only the Indian people can define, decide about the country. It does not matter that Uttar Pradesh is much bigger than Nagaland. The voice of all Indians matter. This is the fight that is taking place. Why do these people want to define India ?. The entire goal to re-define India is to steal from India. The entire idea is to create two Indias. One India for the Ambanis, Adanis, Nirav Modis, Mehul Choksies, Vijay Mallyas and one for others”, Gandhi said lashing out at the Prime minister. He also said poor farmers who took meagre loans of around Rs 20,000 were behind bars for non-repayment while the rich who availed loans over Rs 35,000 crore were walking free. Continuing his tirade against Modi and the RSS, Gandhi said issues of Kerala should be decided by the people and not by Modi or the RSS chief. In the three rallies in Wayanad, Gandhi tore into the BJP-led NDA government and said the saffron party was only interested in imposing its ideology on people of the country. “Who is Mohan Bhagwat to teach us about culture and history? Kerala should be run by the people of Kerala. This is the same sentiment in state after state,” he said.
Redshirt-senior left tackle Jack Mewhort blocks a defender during a game against Penn State at Ohio Stadium. OSU won, 63-14.Credit: Shelby Lum / Photo editorJunior quarterback Braxton Miller and senior running back Carlos Hyde were the offensive stars for Ohio State (8-0, 4-0) once again in the Buckeyes’ 63-14 win against Penn State (4-3, 1-2). However, five players who, on paper, appear to have made less of a dent in the win, also played a crucial role in OSU’s 686-yard offensive performance against the Nittany Lions. So well, in fact, that even a former Buckeye was impressed.Miller (252 passing yards, 68 rushing yards) and Hyde (147 rushing yards) accounted for 467 yards, or 68.1 percent, of OSU’s total offense in the victory.But in order to achieve that success, they needed effective blocking from the offensive line.The starting five offensive linemen — redshirt-senior left tackle Jack Mewhort, senior left guard Andrew Norwell, redshirt-senior center Corey Linsley, redshirt-senior right guard Marcus Hall and sophomore right tackle Taylor Decker — were praised by their coaches and teammates following Saturday’s win.“I see an offensive line that’s one of the best in the country,” coach Urban Meyer said during a post-game press conference. “I’ll take my offensive line anywhere. Those guys are playing very well.”That offensive line led an effort that amassed 32 first downs, averaged 8.9 yard gains per offensive play and converted seven of 10 third downs.“Offensive line did a hell of a job,” Miller said of the unit’s performance Saturday.Miller said the offensive line was “aggressive throughout the week of practice,” and offensive line coach Ed Warinner said the way OSU’s offensive linemen have practiced has led to their success this season.“When you practice the same way — high level — your fundamentals get better, your technique, your understanding and just the whole cohesiveness up front,” Warinner said.Through its first eight games, the OSU offense ranks eighth in the Football Bowl Subdivision in total offense with an average of 517.3 yards per game and fifth nationally with a average 47.3 points scored per game.That offensive success has been a team effort, Warinner said.“(The offense) has the ability to horizontally stretch the field in the run game, and we do it in the pass game, and then vertically stretch you and so we’re putting defenses in a bind,” Warinner said. “They don’t know exactly where to try to load their defense. When you have good players at a lot of positions playing at a high level, which we do right now at receiver, quarterback, running back, O-line, tight end … we can be explosive. We are an explosive outfit right now.”The OSU rushing offense ranks ninth nationally with an average of 295.6 rushing yards per game. Miller said the offensive line’s ability to block on the perimeter has played a key role in OSU’s success running the ball, much like Hall did on a Miller scramble early in the game where he leveled a Penn State defender.“Getting guys the ball on the outside frees up the inside,” Miller said.Warinner said OSU’s success as a rushing offense has been a “credit to a lot of people.”“Running the football is important to us as a program, as a team,” Warinner said. “So that makes it important to the running backs, the O-line and all perimeter guys as well. And then we have the ability to run the ball outside as well as inside and we’re throwing the ball well so we’re just keeping people off-balance.”Norwell said the offensive linemen have “great chemistry” with one another.“We’re all on the same page,” Norwell said. “Coach Meyer knows how many reps we need to get in practice, and we just went hard every play.”One reason for that chemistry might be the experience the offensive linemen have with playing with one another. Mewhort and Norwell are both third-year starters on the offensive line. Hall came into the season with 18 career starts, while Linsley is also a second-year starter.Warinner said he thinks the experience of the offensive line has helped that unit play as well as they have this season.“That it’s helped us a lot, because we can lean on those guys when we need to and they can be productive when they need to,” Warinner said.Warinner said Decker, the only new starter on the offensive line, has fit in well.“His talent level is really high,” Warinner said. “Experience and confidence were the two things he lacked. Now that he’s played eight games and played well these last three or four games, his confidence level is high along with talent level.”Mewhort, Norwell, Linsley, Hall and Decker have each started all eight games for the Buckeyes this season, but with the result of Saturday’s game well in hand by the middle of the third quarter, OSU was able to get playing time for many of its backups, including the offensive line. Warinner said there were 11 offensive linemen in total who received playing time for the OSU offense Saturday.Current OSU coaches and players are not the only Buckeyes impressed by the play of OSU’s offensive line this season. Orlando Pace, who played left tackle at OSU from 1994-96 and was honored on the field during Saturday’s game for being selected to the College Football Hall of Fame, said the OSU offensive line plays “really well together as a unit.”“Those guys, they do a great job in protecting Braxton, and they run the ball well,” Pace said at halftime Saturday.Pace said he expects Mewhort to follow in his footsteps from being an OSU left tackle to playing in the NFL, in which Pace played for 13 seasons.“You’re definitely going to see him play on Sundays,” Pace said. “He moves well, footwork and hand placement and all those things, I think he’ll be fine.”OSU will be looking for another impressive effort from its offensive line when it plays Purdue (1-6, 0-3) Saturday at noon in West Lafayette, Ind.

Citation: Using tellurium nanoparticles to achieve plasmonic-like and all-dielectric properties when exposed to sunlight (2018, August 13) retrieved 18 August 2019 from https://phys.org/news/2018-08-tellurium-nanoparticles-plasmonic-like-all-dielectric-properties.html As the search for renewable resources continues, some in the field have turned to studying the possibility of adding materials to water to make it easier to produce steam for driving a turbine. Several years ago, one team of researchers discovered that adding nanoparticles to water could cause it to produce steam when exposed to sunlight. Since that time, scientists have continued experimenting with adding nanomaterials. Meanwhile, other experiments have suggested that plasmonics could play a role in photothermal conversion. In this new effort, the researchers have found a material that allows nanoparticles to offer the benefits of both approaches.The work by the team in China was straightforward. They created nanoparticles made out of tellurium and then mixed them into a container filled with water and tested the result to see what changes it might have wrought.The researchers report that adding the nanoparticles improved the evaporation rate by a factor of three. Testing showed that they could raise its temperature from 29°C to 85°C in just 100 seconds by shining sunlight on it. The researchers found that this improvement was possible because the nanoparticles behaved like plasmonic nanoparticles—but only when smaller sized nanoparticles (less than 120 nanometers) were involved. Nanoparticles that were larger than 120 nanometers behaved like an all-dielectric. Mixing nanoparticles of both sizes into the same container of water allowed the sample to take on both characteristics—the team claims the resultant material is the first to demonstrate both properties.The researchers acknowledge that commercialization of their technique would be problematic because of the difficulty in manufacturing the different sized nanoparticles in sufficient quantities. They note that they are looking into ways to make them using another approach. But they also note that if they succeed, the concept has other applications, such as creating new kinds of extremely small antennas or sensors. © 2018 Phys.org Explore further More information: Churong Ma et al. The optical duality of tellurium nanoparticles for broadband solar energy harvesting and efficient photothermal conversion, Science Advances (2018). DOI: 10.1126/sciadv.aas9894AbstractNanophotonic materials for solar energy harvesting and photothermal conversion are urgently needed to alleviate the global energy crisis. We demonstrate that a broadband absorber made of tellurium (Te) nanoparticles with a wide size distribution can absorb more than 85% solar radiation in the entire spectrum. Temperature of the absorber irradiated by sunlight can increase from 29° to 85°C within 100 s. By dispersing Te nanoparticles into water, the water evaporation rate is improved by three times under solar radiation of 78.9 mW/cm2. This photothermal conversion surpasses that of plasmonic or all-dielectric nanoparticles reported before. We also establish that the unique permittivity of Te is responsible for the high performance. The real part of permittivity experiences a transition from negative to positive in the ultraviolet-visible–near-infrared region, which endows Te nanoparticles with the plasmonic-like and all-dielectric duality. The total absorption covers the entire spectrum of solar radiation due to the enhancement by both plasmonic-like and Mie-type resonances. It is the first reported material that simultaneously has plasmonic-like and all-dielectric properties in the solar radiation region. These findings suggest that the Te nanoparticle can be expected to be an advanced photothermal conversion material for solar-enabled water evaporation. This document is subject to copyright.

, Nature Materials © 2019 Science X Network The idea of forming a quasi-2-D superconducting layer at the interface between two different compounds has been around for several years. One past study, for instance, tried to achieve this by creating a thin superconducting layer between two insulating oxides (LaAlO3 and SrTiO3) with a critical temperature of 300mK. Other researchers observed the thin superconducting layer in bilayers of an insulator (La2CuO4) and a metal (La1.55Sr0.45CuO4), neither of which is superconducting in isolation.”Here we put forward the idea that thin charged layer on the interface between ferroelectric and insulator is formed in order to screen the electric field,” Viktor Kabanov and Rinat Mamin, two researchers who carried out the study, told Phys.org via email. “This thin layer may be conducting or superconducting depending on the properties of the insulator. In order to get a superconducting layer, we chose La2CuO4 – an insulator that becomes a high Tc superconductor when it is doped by carriers.”The heterostructure fabricated by Kabanov, Mamin and their colleagues consists of a ferroelectric magnetron sputtered on the surface of the parent compound of high Tc superconductor La2CuO4. At the interface between these two components, the researchers observed the appearance of a thin superconducting layer, which attains its superconductivity at temperatures below 30K. The researchers detected the layer’s superconducting properties by measuring its resistivity and via the Meissner effect. They found that a finite resistance is created when applying a weak magnetic field perpendicular to the interface, which confirms the quasi-2-D quality of the layer’s superconductive state. “The key advantage of our technique is the relative simplicity of the creation of the heterostructure, because the requirements for the roughness of the surface are not so stringent,” Kabanov and Mamin said. “On the other hand, the changing the polarization in the ferroelectric allows to control the properties of the conducting layer.” Kabanov, Mamin and their colleagues are the first ever to observe superconductivity on the interface between a ferroelectric and an insulator. In the future, their approach and the superconductors they fabricated could inform the design of new electronic devices with a ferroelectrically controlled superconductivity. “As far as plans for the future are concerned, we would like to learn how we can control the superconducting properties of the interface by rotating the polarization of the ferroelectric,” Kabanov and Mamin said. “Another idea is to try to control the properties of the interface by laser illumination. This is basically the direction we are working on now.” Researchers at the Zavoisky Physical-Technical Institute and the Southern Scientific Center of RAS, in Russia, have recently fabricated quasi-2-D superconductors at the interface between a ferroelectric Ba0.8Sr0.2TiO3 film and an insulating parent compound of La2CuO4. Their study, presented in a paper published in Physical Review Letters, is the first to achieve superconductivity in a heterostructure consisting of a ferroelectric and an insulator.
