MANILA, Philippines—Looking flat out devastated when he left Cuneta Astrodome following their opening game against Columbian, Chris Ross had this fire in his eyes when he took on crowd darlings Barangay Ginebra.ADVERTISEMENT That couldn’t be more evident when his sights aimed for the bucket in the third period of the game. Ross, only five points in the first two frames, waxed hot for 12 more that quarter to help the Beermen erect a comfortable lead heading into the stretch.“I knew I had to be a little more aggressive because Alex and Terrence were out,” Ross told the press after San Miguel’s 99-91 victory over Ginebra in Sunday’s nightcap.FEATURED STORIESSPORTSPrivate companies step in to help SEA Games hostingSPORTSUrgent reply from Philippine football chiefSPORTSWin or don’t eat: the Philippines’ poverty-driven, world-beating pool stars“I just wanted to get going offensively and make plays for my team, so luckily my team was giving me the confidence to keep going, and I just kept going,” he said.Ross ended the game with 22 points—only second to Christian Standhardinger’s 26—to go with eight assists and six rebounds. LATEST STORIES View comments MOST READ The 33-year-old playmaker credits his prolific performance to a long break.“I went [back] to the States,” Ross said. “It was the longest off-season I’ve had in a while, so I got to get back to my old high school and just get a lot of shots in.”Ross made six pointers and figured as the spearhead of that Beermen charge in the third quarter which widened the gap by as many as 23 points.“Coming into the game, it was the trust they gave me,” Ross said. But he was also quick to had that he had help—in the form of Von Pessumal’s equally prolific marksmanship and Marcio Lassiter’s clutch basket.“Those guys are big time players. Von really had a good preseason … He came in a little bit stronger, gained a little more weight. He’s really been performing well for us in the tune-ups. And, you guys know what Marcio can do. So it was a fact of us kinda just waking up after that first game, coming out and playing well,” he said.ADVERTISEMENT “We got it from everybody,” Ross added.Ross’ words of optimism, though, were also adorned with caution: That the Beermen are far from perfect.“This thing’s not going to be easy,” he said. “it’s going to take some time especially integrating Terrence (Romeo), and Christian and Paul (Zamar). And coach is giving Von more minutes, [along with] Kelly Nabong.”And as much as their offense was a big factor in the result, Ross pointed that their effort on the defensive end was just as crucial.“Our defense was really good today, and we know we’re going to get back to that if we want win games,” he said.Sports Related Videospowered by AdSparcRead Next US judge bars Trump’s health insurance rule for immigrants SEA Games hosting troubles anger Duterte Hamstring injury sidelines San Miguel’s Alex Cabagnot Oil plant explodes in Pampanga town Private companies step in to help SEA Games hosting PH underwater hockey team aims to make waves in SEA Games PLAY LIST 02:42PH underwater hockey team aims to make waves in SEA Games01:44Philippines marks anniversary of massacre with calls for justice01:19Fire erupts in Barangay Tatalon in Quezon City01:07Trump talks impeachment while meeting NCAA athletes02:49World-class track facilities installed at NCC for SEA Games02:11Trump awards medals to Jon Voight, Alison Krauss Don’t miss out on the latest news and information.

People who put up five, six, 10tweets in a few minutes, all with links to the event they’re at, or worse, totheir promotional stuff, are annoying. I probably couldn’t say what exactlyTwitter is supposed to do, but I can tell you, from my perspective, that’s notit. In December I signed up for Twitter. I’dbeen meaning to do it for a while, but hadn’t, because a) I’m not really anearly adopter and b) I wasn’t sure where another social network fit into myschedule, which already has Facebook,Flickr and mediaPRO. But I believe in Rex Hammock’s philosophy of experimenting innew forms of media, so it had been on my list of things I needed to do. AndI get all the potential value, from both the marketing and journalisticperspectives, among others. The catalyst was a lunch I had withMichael Biggerstaff and Marcus Grimm at NxtbookMedia. They were really into Twitter at the time, and said it was a quickerform of communication than blogging, and that you’re more likely to updatebecause the “tweets” have to be quick hits. Twitter does a spotty jobtechnically. Every few days, a bunch of people report they lost all the tweetsthey posted that day. The noise level is out ofcontrol. It’s not a conversation, it’s a cacophony. It’s like a cocktail partyfrom hell, where everyone is shouting at the same time, and someone also jackedup Led Zeppelin in the other room. If social media is aconversation, it’s barely there on Twitter. People overwhelmingly tweet at eachother. Apparently, conversation is rarely needed or desired. Twitter is,ironically, a one-way communication vehicle in a medium that is supposed to besocial. So I signed up and built a network. Some of the people I follow are reallygood. Dan McCarthy (@danielmccarthy), Jeff Klein (@jeffreysklein), Kurt Andersen(@kbandersen), who does a great job of adding personal but business-relevanttouches), Rachel Sklar (@rachelsklar), and Rex (@r) himself come to mind. So do Ted Bahr (@tedbahr), Eric Gervase(@egervase) and Red 7’s own Loree Stark (@loreestark). Harry McCracken (@harrymccracken),Scott Karp (@scottkarp) and Dylan Stableford (@stableford) are good. Gawker(@gawker) does a great job.FOLIO: (twitter.com/foliomag) and AudienceDevelopment (twitter.com/auddevmag) both signed up recently. Someone asked me last week why ITwitter, and why FOLIO: and Audience Development Twitter, and I said I thoughtthe value was thought leadership, not traffic. If you build a network ofinfluential people, and put out brief and thoughtful tweets (not always linkingto something), there’s real value. I have just under 100 followers and Ifollow about the same amount of people. And here’s the way I feel about Twitterright now: Twitter does a poor jobcontrolling spamming and bogus accounts. If you’re active at all, you get hitwith “follow” requests that are spurious, completely unrelated, sketchy, andyou have to check out the profile to tell what the hell they are. All thesecomplaints aside, I check Twitter several times a day and tweet every day, andas I mentioned, some of the people in my network really get it and bringinsight, perspective and inspiration.

The free-standing features could be encapsulated in stretchable, conformal configurations. Park et al. demonstrated applications in the form of reconfigurable antenna, tunable by changing geometries and reversibly movable interconnections to use the constructs as mechanical switches. The free-standing 3-D structures were advantageous to minimize the number and space between interconnections for higher integration, as seen with microLED arrays. The results are now published on Science Advances. Advanced technologies that form 3-D conductive structures with high-resolution, high aspect ratios and minimal error of displacement are important to increase device integrity. Device deformability is a key consideration for free-form electronics, including stretchable electronics, wearable electronics, soft actuators and robotics. These electronic devices typically require conformation with movable, arbitrary shapes such as joints or arms, or the soft surfaces of living organisms. Realizing such stretchable devices with conventional materials such as silicon are a challenge due to their brittleness. Materials scientists have therefore developed diverse conductive materials with excellent stretchability in the form of wavy thin metals, metallic networks and elastomeric composites, yet these processes are unable to form scalable 3-D structures. In addition, 3-D printed, and thermally annealed metals are relatively stiff and rigid causing damage to soft, tissue-like substrates. In the experimental setup, Park et al. connected a nozzle to an ink reservoir or pressure controller. The materials scientists used EGaIn (75.5 percent gallium and 24.5 percent indium alloy by weight) as the ink and controlled the distance between the nozzle tip and polymer substrate to deliver the ink. Using scanning electron microscopy (SEM), they viewed the EGaIn pattern printed with complex 2-D and 3-D geometries and used the technique to print more diverse patterns such as interconnects of electric circuits with high resolution.

Credit: Science Advances, doi: 10.1126/sciadv.aaw2844 Journal information: Science Advances Comparatively, liquid metals such as eutectic gallium-indium alloy (EGaIn) or gallium-indium-tin alloy (Galinstan) are intrinsically stretchable, with low toxicity and minimal volatility for superb electrical conductivity—comparable to solid metals. Direct ink printing with a nozzle can form free-standing 3-D structures at room temperature by stacking droplets of liquid metal upon one another but the resulting resolution is not suited to build electronic devices. In the present work therefore, Park et al. report a high-resolution printing method with liquid metal for its direct reconfiguration into 3-D electrode patterns through a nozzle, under ambient conditions. When they applied DC or AC bias to monitor electrical breakdown, the temperature too increased in the experimental setup affecting the mechanical stability of the EGaIn 3-D features. The constructs maintained their initial free-standing 3-D structure without structural collapse at 5000C for 30 minutes. After repeated heating and cooling at room temperature, the oxide skin of the 3-D feature slightly wrinkled due to thermal expansion between the oxide shell and EGaIn core. Park et al. tested the electrical contact of direct-printed and reconfigured liquid metals and measured the dependence of total resistance on the length of the printed channel to show that the resistance of EGaIn patterns significantly increased with time under ambient conditions. As a proof-of-principle of the reconfigurable electronics developed in the present work, Park et al. demonstrated the formation of a reconfigurable antenna with ability to modify its resonance frequency and radiation properties by changing its geometry. For this, the scientists formed a dual coil antenna structure on a glass slide by directly printing EGaIn. During reconfiguration, EGaIn formed a 3-D bridged interconnect, whose resonance frequency the scientists first determined, followed by their use to selectively operate three different light-emitting diodes (LEDs) with red, green and blue light emissions. The reconfigurable, free-standing interconnect maintained its resistance to reliably operate all LEDs at 3V during repeated detachment and connection of multiple reconfiguration steps. The free-standing 3-D interconnects formed using the process of reconfiguration were advantageous to build cross-geometries in a single XY plane, instead of using multiple layers to thereby prevent unwanted electric contact. For this, Park et al. demonstrated both transverse and longitudinal interconnects of EGaIn for a 4 x 4 array of microLEDs on a flexible polymer film to prevent short circuiting. Using the method, Park et al. minimized the number of interconnections integrated in a miniature device, as the 3-D pattern could efficiently minimize the number and space of interconnections. In this way, Young-Geun Park and co-workers demonstrated high-resolution 3-D printing using liquid metal and showed its application for stretchable 3-D integrations that are difficult to achieve with conventional engineering. Compared to existing 3-D printing techniques, this method can form fine, free-standing 3-D structures of electrodes with reconfigurable patterns. As an example, Park et al. engineered a reconfigurable antenna capable of modifying its resonance frequency via geometric changes. They also presented reversibly movable 3-D interconnections as mechanical switches that could facilitate higher compact integration in miniaturized devices. The scientists expect the high-resolution 3-D reconfiguration method to offer a promising new additive manufacturing strategy for highly integrated and stretchable next-generation electronic devices.

The fracture energy of the oxide skin connected the nozzle tip as a “rope” during lift-off. Park et al. measured the maximum velocities for different diameters of filaments to demonstrate different examples and formed 2-D and 3-D features with repeatable reconfiguration. During the process of reconfiguration, the scientists could lift-off a preprinted filament upright from a substrate without fracturing the construct. The observed stable electrodes could withstand electrical load to become increasingly integrated and miniaturized in electric devices. To verify the suitability of EGaIn electrodes as interconnects, Park et al. conducted electrical breakdown tests thereafter. This document is subject to copyright.
