Chrysler Share your voice Enlarge ImageAffected owners will be notified by mail in April. Chrysler Occasionally, an automaker initiates a recall because it discovered a problem during routine inspections. Other times, a recall can come about because of reports from vehicles already in the field. Chrysler’s latest recall stems from the latter.Chrysler has issued a recall for approximately 48,000 examples of the 2018 Chrysler Pacifica minivan. The vehicles in question were all built at the Windsor Assembly Plant in Canada between Nov. 1, 2017 and Feb. 28, 2018, and that build range coincides with an increase in warranty claims for “buzz, squeak and rattle” related to the defect that spurred the recall.The problem stems from the suspension system. According to Chrysler’s recall documents, “a combination of loss of clamp load and inadequate joint engagement” might cause the right front lower control arm to come loose from the steering knuckle. If this happens, the driver might lose directional control of the vehicle, which can increase the risk of a crash.Chrysler discovered the problem after receiving a field report of this part separation, after which point it launched an investigation to determine what was happening. As of Feb. 18, the automaker says it is not aware of any accidents or injuries related to the issue. The automaker already has a remedy in place. After returning the recalled vehicles to dealerships, Chrysler technicians will inspect the right front steering knuckle and lower control arm, and the parts will be replaced as needed. Technicians will also install a larger pinch bolt. As with every recall fix, it will be performed free of charge, and the automaker will reimburse owners who paid for a repair prior to the recall announcement.

Prithvi Shaw topped the scorer’s charts with 237 runs in his maiden Test series.IANSIndian opener Prithvi Shaw has been in the news for the wrong reasons recently. He was suspended by the BCCI on charges of a doping violation.As per a statement of BCCI reported by IANS, Shaw had unintentionally ingested a prohibited substance, which can be commonly found in cough syrups. His urine sample contained Terbutaline.The statement of the board said, “Shaw had provided a urine sample as part of the BCCI’s anti-doping testing programme during the Syed Mushtaq Ali Trophy match on February 22 in Indore. His sample was subsequently tested and found to contain Terbutaline. Terbutaline, a specified substance, is prohibited both In & Out of Competition in the WADA Prohibited List of Substances.”The statement further went on to say that Shaw has accepted the charges by explaining that due to having a cough he took a cough syrup over the counter which contained the substance. The BCCI accepted his explanation and he was banned till November 15.But, Mumbai team coach Vinayak Samant and physio Deepak Tomar have reportedly mentioned that the player who was with them when they travelled to Indore for the Syed Mushtaq Ali Trophy did not complain of any cough or cold, as reported by the Times of India. Even team manager Ganesh Iyer also stated that the 19-year-old player did not inform him either. Can young Prithvi Shaw give the Daredevils another flying start?IANS “He had slight fever. But there were no symptoms of cough or cold. Neither did he approach us with any complaints, nor did he ask for remedy. We were available at all times,” Samant and Tomar told TOI.”I noticed he had some cold. But he did not come and tell me anything,” Ganesh Iyer told TOI.According to the BCCI report prepared by board’s anti-doping manager Abhijit Salvi with information from National Cricket Academy (NCA) head Toofan Ghosh and head physiotherapist Ashish Kaushik, it read that Shaw consulted his father who told him to go to a pharmacy and get the medicine.The report read, “He consulted his father, who suggested he visit a pharmacy to obtain a remedy for his symptoms. Shaw visited a local pharmacy close to the hotel in Indore, where a pharmacist recommended to him an over-the-counter syrup that he said would provide immediate relief.”According to sources close to Shaw informed TOI that the cricketer is hardly in touch with his father as he has been living with Shiv Sena MLA from Mumbai Sanjay Potnis for the last 10 years. So it is very unlikely that he will talk to his father.According to the report, Shaw knew that cough syrups contain the prohibited substance. Then why did he consume it?Tomar further added that Prithvi came to him and mentioned that he was not feeling well but never talked about having a cough and cold.”Prithvi came to me once saying he’s not feeling well and I asked him to rest. But at no point did he say he has cough or cold,” Tomar told TOI.All these information raise many questions on how BCCI settled the case of doping with Shaw.
New nanotube material stays rubbery over a more than 1,000 degree temperature range The researchers, grad student Peiwen Zheng and Professor Thomas J. McCarthy from the University of Massachusetts, have published a paper on the rediscovery of siloxane equilibration in a recent issue of the Journal of the American Chemical Society.“We have been working on silicone materials from a couple of different perspectives,” Zheng told PhysOrg.com. “When we rediscovered the forgotten unusual properties of silicones and combined them with today’s research interests, we found that the silicone material with the siloxane equilibration was an obvious candidate for a self-healing material.”The researchers performed several experiments to test the theoretical predictions from papers published in the early 1950s, as well as to extend some of the experiments performed at that time. In one experiment, Zheng and McCarthy prepared a siloxane-based mixture containing a cross-linking agent and a catalyst. Then they poured the solution into molds of various shapes, such as cylinders, disks, and dog bones. After heating the molds at 90 °C (194 °F) for four hours, the researchers removed clear, rubbery silicone shapes from the molds. The scientists described these silicone samples as “living polymer networks.” More information: Peiwen Zheng and Thomas J. McCarthy. “A Surprise from 1954: Siloxane Equilibration Is a Simple, Robust, and Obvious Polymer Self-Healing Mechanism.” Journal of the American Chemical Society. DOI: 10.1021/ja2113257 (PhysOrg.com) — Research in self-healing organic polymers has grown recently, but one simple self-healing mechanism from more than 60 years ago has been nearly forgotten until now. Using this mechanism, which is called “siloxane equilibration,” scientists have demonstrated that silicone rubber that has been cut in half with a razor blade can completely repair itself through heat-activated reversible bonding. The self-healing mechanism could have applications in a variety of areas, such as for designing self-healing surfaces of vehicles and countertops.

Image credit: Zheng, et al. ©2012 American Chemical Society “The silicone network is at a chemically anionic equilibrium,” Zheng explained of the term, “where the reactive center will cleave and reform a covalent siloxane bond.” These bonds are reversible, which enables the two sides of a crack to reconnect under the right conditions.To demonstrate the self-healing ability, the researchers cut a 1-cm-long cylindrical sample in half using a razor blade. Then they rejoined the two pieces by wrapping them together with Teflon plumbing tape and heating them in an oven at 90 °C (194 °F) for 24 hours. When the researchers retrieved the sample and removed the tape, they found that the silicone cylinder had completely healed. Then they bent the cylinder by hand until it broke again – significantly, it broke in a different location than where it had been cut. The scientists repeated this experiment on different shaped objects with the same results. This document is subject to copyright.

Journal information: Journal of the American Chemical Society In another experiment, the researchers molded a silicone dog bone, which they cut into multiple pieces. Then they rearranged the pieces to fit into a mold of a dog. Heating the sample resulted in a silicone dog with no visible fractures or weak spots where the pieces had been fitted together.The researchers also quantified the strength of the healed samples in comparison with the original samples using fracture toughness measurements. The data for the two types of samples was indistinguishable, indicating exceptional self-healing.The researchers explained that, in principle, any cross-linked dimethylsilicone elastomer (only one type was used here) can be converted into a living elastomer by the addition of basic catalysts. This possibility opens up many different routes for synthesizing a variety of self-healing silicione-based materials. While the samples used here required applied heating to self-heal, the researchers predict that samples in a sealed, high-temperature environment would self-heal “autonomically,” or automatically. Zheng explained that self-healing materials, with some improvements, could lead to a variety of applications.“It can be developed into self-healing coatings on auto vehicles or countertops,” she said. “It is also a ‘plastic’ elastomer which can be used in molding to form desired shapes and patterns. The concept of a self-healing silicone can be used to guide the preparation of elastomers with gradient modulus, Janus elastomers, reversible surface patterns when filled with magnetic particles, and super tough materials which can chemically relax stress.” Explore further (A) A silicone sample in the shape of a cylinder.

November 28, 2018 Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now 4 min read Jane Buckingham started trend-hunting at age 17, when she wrote her first book, Teens Speak Out. Some three decades later, she’s still hot on the scent — and still hanging out with teens, because doing so provides a keyhole view of the future. “They’re not so set in their ways, so that’s where you see change happening,” Buckingham says. The firm she founded in 2009, Trendera, forecasts what’s next through deep research and consumer surveys on everything from technology to gender fluidity. Entrepreneurs should pay particular attention to shifts in culture, she says, “because when attitudes change, there’s always opportunity.”Related: The Young Founder of This Celebrity-Loved Activewear Company Shares Why You Should Always Trust Your InstinctsWhat macro trends are you seeing in 2019? Entertainment is all about to change. Youth culture is where trends often take root. There’s a company called Brat that’s doing 10- to 15-minute shows online for teens. Let’s call it a Sweet Valley High meets Riverdale. They’re acting like a TV channel but using social media as direct marketing and making it the primary draw. They’re getting, like, two million views an episode. I think we’ll see a shift to our phones as our central entertainment system. That’s a huge opportunity. Give us another big trend.“Have it your way” to the 98th degree. “I want what I want, when I want it.” On-demand and personalizing will trump everything. For example, cars are one of the least customizable big purchases. I have to imagine that’s an area that could ultimately explode. One of Trendera’s reports this year talks about self-protection.We’re entering an unfortunate period of totally excused bad behavior. We’re going to see more safeguarding developments — whether it’s a nail polish that tells you if your drink has been roofied, or a digital contract that allows college students to tape themselves during sex so they can prove it wasn’t rape.Related: Isn’t It Time to Be Your Own Boss? These Women-Founded Companies Want You to Join the Movement.Are you making this up? Oh, totally! I don’t know what that looks like, but people will become self-protective. But a more positive trend is health. Aren’t we already obsessed with health?What’s new is the integration of wellness into everything — from work to school to food to parenting. It’s one of the few things we feel we can control, so it’s a gold mine for entrepreneurs.What’s in your crystal ball with tech?Have you seen this workout device called Mirror? You work out in front of it with a virtual trainer in the mirror showing what to do. That’s going to be the next evolution. So you’re going to have technology in your kitchen where someone walks you through the recipes, and tech where someone scans your closet and tells you, “Oh, you know what would be a great outfit for today?” Related: Millennial Women Are Facing Serious Burnout — Here’s How to Beat ItAre you seeing opportunities to invent these tech products or use them? Both. There are tons of areas for entrepreneurs to ask: How do we make technology feel more human by incorporating people? And on the business side, it’s everything from better bots to better customer service to better shipping and delivery. It’s all going to just get more connected. That sounds great.Till the robots overtake us. Because we really have seen this movie, right? We all know how it ends [laughs].
