What followed has been a masterclass in making it as an independent artist Prof leaned into the fantastical tales and dynamic persona that have cultivated his rabid fan base. Released in November, 2020, Powderhorn Suites reached a career-high #3 on the Billboard Current Rap Albums charts, #5 Top New Artists Albums, #15 Independent Album, and #36 Billboard Top Albums. His most recent album, Powderhorn Suites, shocked pundits and industry alike with an amazing run through the charts and streaming platforms. His seventh studio album, Horse, due out on his own Stophouse Music Group label April 14, 2023, is set to let the world at large in on a secret that music fans already know, Prof is a force to be reckoned with. Coming out of Minneapolis, Minnesota, Prof has perfected the art of combining blue collar hard work and unimpeachable content with never taking himself too seriously. It's long been held that, in order to suppress dendrite growth, the separator inside the battery must be stronger than the metal it is trying to suppress, but Choudhury's porous polymer separator - with average pore sizes below 500 nanometers - were shown to arrest the growth.Event Details With lyrical skill matched only by his raucous live shows, Prof has arrived on the national stage. "What Sne was able to do was design a cell that allowed us to, very elegantly, visualize what is occurring at the lithium-metal interface, giving us now the ability to go beyond theoretical predictions."Īnother novelty of this work, Archer said, is "overturning something of a canon" in battery science. students' lifetimes," said Archer, who's been at Cornell since 2000, with a laugh. "This is something I've wanted to do for, I guess, three Ph.D. The group confirmed theoretical predictions about dendrite growth with Choudhury's device. Choudhury and Dylan Vu - a rising junior majoring in chemical engineering - are co-first authors.Ĭhoudhury, who is headed to Stanford University for his postdoctoral work, also devised a method for direct visualization of the inner workings of their experimental battery. Their paper, "Confining Electrodeposition of Metals in Structured Electrolytes," was published in Proceedings of the National Academy of Sciences. Using a reaction procedure the Archer group introduced in 2015, they employ "cross-linked hairy nanoparticles" - a graft of silica nanoparticles and a functionalized polymer (polypropylene oxide) - to create a porous electrolyte that effectively lengthens the route ions must take to travel from the anode to the cathode and back, dramatically increasing the life of the anode. Choudhury's solution: Confine dendrite growth by the structure of the electrolyte itself, which can be controlled chemically. Solid electrolytes have been shown to suppress dendrite growth mechanically, but at the expense of fast ion transport. If the dendrite breaks through the separator and reaches the cathode, short-circuiting and fire can occur. '18, has come up with what Archer terms an "elegant" solution to a fundamental problem with rechargeable batteries that use energy-dense metallic lithium anodes: sometimes-catastrophic instability due to dendrites, which are spines of lithium that grow from the anode as ions travel back and forth through the electrolyte during charge and discharge cycles. "You need a kind of radical mindset change," he said, "and that means that you've got to almost start at the beginning." Minor engineering tweaks may lead to better batteries with more storage, but this is not a long-term solution." "The lithium-ion battery, which has become the workhorse in powering new electronics technologies, operates at over 90 percent of its theoretical storage capacity. "What we have now is actually at the limits of its capabilities," said Archer.
