SAN JOSE, CA (AP) — The San Jose Sharks are in a freefall at most inopportune time.Dylan Larkin scored in the first minute, Jonathan Bernier had 38 saves and the Detroit Red Wings beat the Sharks 3-2 on March 25.The Red Wings have won four of their last five games after going 1-9-3 over their previous 13.The Sharks lost their season-high sixth (0-5-1) straight game. It’s their longest skid since going 0-6-0 in March 2017.Larkin scored his 28th goal on a breakaway 38 seconds into the first period, faking a forehand shot before slipping a backhander past Martin Jones, who finished with 20 saves.“It was the first shift of the game they scored, and it seems like that’s been happening too often lately,” Sharks center Logan Couture said. “We’re falling behind 1-0 early, and then you’re fighting to get back in it. We got to figure out a way to get leads.”San Jose is in second place in the Pacific Division, six points behind Calgary, which lost to Los Angeles 3-0. The Sharks maintained a five-point lead over third-place Vegas, which lost to St. Louis, 3-1.San Jose has just six regular-season games remaining. The Sharks have already clinched a playoff spot.“I don’t know if there’s a complacency about where we’re sitting in the standings or what, but we’ve got to get out of it,” San Jose Sharks coach Peter DeBoer said.Andreas Athanasiou scored his 29th goal on a breakaway with just under five minutes left in the second period.Athanasiou has seven points (five goals, two assists) in his last five games.Red Wings rookie forward Taro Hirose assisted Athanasiou’s goal. He has an assist in his first four NHL games.“He’s really impressive, It doesn’t seem like there’s any panic in his game ever,” Larkin said. “He’s so calm with the puck. It’s clear that he wants to hold onto it and make plays.”The Red Wings opened up a 3-0 lead when Christoffer Ehn scored a short-handed goal at 8:35 of the third period.Evander Kane scored his 28th goal for San Jose on the power play 20 seconds later.Tomas Hertl scored his 33rd goal with four seconds left in the game.Three of Detroit’s last four wins have been against contending teams (Islanders, Golden Knights, Sharks).“I think these are obviously unbelievable teams and they’ve got great players, and for us to come here on the road and show what we can do is huge for our team’s success and our confidence in this room,” Hirose said.San Jose’s three most recent losses have been to teams with losing records (Los Angeles, Anaheim and Detroit).“I didn’t think we had great energy until the third period,” DeBoer said. “I thought we had desperation in the third, but we need it for 60 minutes. We only came with 20 of it. That’s what you get in this league. I don’t care who you play, if you don’t play with the proper amount of desperation and work in your game as the other team has, and they had that tonight, you get the results you get.”By Gideon Rubin, Associated PressTweetPinShare0 Shares
Evacuations ordered as bomb squad investigates suspicious device in Lemon Grove January 17, 2018 Posted: January 17, 2018 Categories: Local San Diego News FacebookTwitter KUSI Newsroom SAN DIEGO (KUSI) — Evacuations were ordered in Lemon Grove after a suspicious device was found Wednesday near a U-Haul center.A bomb squad was sent to a self-storage business in the 1800 block of Massachusetts Avenue, near Main Street in Lemon Grove, where a caller reported finding what appeared to be a “military practice device,” a sheriff’s lieutenant says.Bomb squad personnel have safely impounded that possible piece of military equipmentDeputies evacuated the immediate area and shut down some traffic lanes as a precaution pending resolution of the situation.Officials have reopened the area to the public.

Various samples of the light-printable paper. Credit: Wang et al. ©2017 American Chemical Society Rewritable material could help reduce paper waste The researchers, Wenshou Wang and coauthors at Shandong University in China; the University of California, Riverside; and Lawrence Berkeley National Laboratory, have published a paper on the light-printable rewritable paper in a recent issue of Nano Letters.”The greatest significance of our work is the development of a new class of solid-state photoreversible color-switching system to produce an ink-free light-printable rewritable paper that has the same feel and appearance as conventional paper, but can be printed and erased repeatedly without the need for additional ink,” Yadong Yin, Chemistry Professor at the University of California, Riverside, told Phys.org. “Our work is believed to have enormous economic and environmental merits to modern society.”Currently, paper production and disposal have a large negative impact on the environment: paper production is a leading source of industrial pollution, discarded paper is a major component (approximately 40%) of landfills, and even recycling paper contributes to pollution due to the process of ink removal. There is also the issue of deforestation: in the US, about one-third of all harvested trees are used for paper and cardboard production.Working to address these problems, researchers have been investigating alternatives to disposable paper. One possibility is to take advantage of the color-switching ability of certain chemicals when exposed to light, although in the past this approach has faced challenges in terms of stability, limited reversibility, high cost, toxicity, and difficulty in applying the coating to ordinary porous paper.The light-printable paper developed in the new study improves in all of these areas, bringing the technology closer to applications, which could include any medium on which information is printed and needed for only a short time.”We believe the rewritable paper has many practical applications involving temporary information recording and reading, such as newspapers, magazines, posters, notepads, writing easels, product life indicators, oxygen sensors, and rewritable labels for various applications,” Yin said. When the Prussian blue and TiO2 nanoparticles are evenly mixed and coated onto paper, the plain unprinted paper appears solid blue. To print text or images, the paper is exposed to UV light, which photoexcites the TiO2 nanoparticles. These nanoparticles then release electrons that are picked up by the adjacent Prussian blue nanoparticles, which turn from blue to colorless. Since it’s easier to read blue text on a colorless background than colorless text on a blue background, it’s the background rather than the text that is typically printed by light, turning colorless (although the paper can also be “reverse-printed” to show colorless text on a blue background). Different colors besides blue can also be achieved by using Prussian blue analogues of various colors.Once printed, the paper retains its configuration for at least five days with high (5-µm) resolution, and then slowly fades back to solid blue through oxidation under ambient conditions. To erase the paper more quickly, the paper can be heated for about 10 minutes to return it to its solid blue state. The researchers predict that light-printable paper will be inexpensive when produced on a commercial scale.”The light-printable paper is indeed cost-competitive with conventional paper,” Yin said. “The coating materials are inexpensive, and the production cost is also expected to be low as the coating can be applied to the surface of conventional paper by simple processes such as soaking or spraying. The printing process is also more cost-effective than the conventional one as no inks are needed. Most importantly, the light-printable paper can be reused over 80 times, which significantly reduces the overall cost.”Future plans focus on bringing the technology closer to practical use.”Our immediate next step is to construct a laser printer to work with this rewritable paper to enable fast printing,” Yin said. “We will also look into effective methods for realizing full-color printing.” Citation: No ink required: paper can be printed with light (2017, February 2) retrieved 18 August 2019 from https://phys.org/news/2017-02-ink-required-paper.html Journal information: Nano Letters Explore further (Phys.org)—In an effort to curb the adverse environmental impacts of paper production, researchers in a new study have developed a light-printable paper—paper that can be printed with UV light, erased by heating to 120 °C (250 °F), and rewritten more than 80 times. The secret to printing with light lies in the color-changing chemistry of nanoparticles, a thin coating of which can be easily applied to conventional paper to transform it into the light-printable version. © 2017 Phys.org Light-printable rewritable paper showing a quote by Richard Feynman.
