Four College of Sciences alumni have been selected as members of the 2024 class of 40 under 40. 

A groundbreaking new study published in Nature Physics has revealed that geometry influences biofilm growth more than anything else, including the rate at which cells can reproduce. The research shows that the fitness of a biofilm is largely impacted by the contact angle that the biofilm’s edge makes with the substrate.

The team used experiments and simulations to quantify and predict how knit fabric response can be programmed. By establishing a mathematical theory of knitted materials, the researchers hope that knitting — and textiles in general — can be incorporated into more engineering and manufacturing applications.

The Center for Teaching and Learning (CTL) and the Office of Academic Effectiveness (OAE) are thrilled to announce the Spring 2024 Course Instructor Opinion Survey (CIOS) Honor Roll. Faculty members at Georgia Tech who made the Spring 2024 Honor Roll have been celebrated by their students for outstanding teaching and educational impact.

Every few seconds, somewhere in the observable Universe, a massive star collapses and unleashes a supernova explosion. Physicists say Japan’s Super-Kamiokande (Super-K) observatory might now be collecting a steady trickle of neutrinos from those cataclysms — amounting to a few detections a year.

In an article published in Nature, School of Physics Professor Ignacio Taboada provides a brief commentary on this new research: "The data from Super-K are still too weak to claim a discovery, but the prospect of detecting the diffuse neutrinos is extremely exciting”, says Tabaoda, who is also the spokesperson for the IceCube neutrino observatory at the South Pole. “Neutrinos would provide an independent measurement on the history of star formation in the Universe.”

Groundbreaking research is shedding new light on how biofilms grow — using physics and mathematical models. Biofilms grow everywhere — from plaque on teeth, to medical devices, to the open ocean. But until now, it’s been difficult to study just what controls their growth. In a new study published in Nature Physics, researchers from the Yunker Lab in the School of Physics, including Lead Researcher Aawaz Pokhrel and Associate Professor Peter Yunker, leveraged physics to show that a biofilm’s geometry is the single most important factor in determining growth rate — more important than even the rate at which cells can reproduce. Since some research shows that 80% of infections in human bodies are caused by the bacteria in biofilms, understanding how colonies grow has important human health implications, potentially to help reduce their impact in medical settings or industrial processes.

Recent demonstrations of moiré magnetism, featuring exotic phases with noncollinear spin order in the twisted van der Waals (vdW) magnet chromium triiodide CrI3, have highlighted the potential of twist engineering of magnetic (vdW) materials. In this paper, researchers, including School of Physics assistant professors Hailong Wang and Chunhui Du, reported the observation of two distinct magnetic phase transitions with separate critical temperatures within a moiré supercell of small-angle twisted double trilayer CrI3.

An observatory still under construction at the bottom of the Mediterranean Sea has spotted what could be the most energetic neutrino ever detected. Such ultra-high-energy neutrinos — tiny subatomic particles that travel at nearly the speed of light — have been known to exist for only a decade or so, and are thought to be messengers from some of the Universe’s most cataclysmic events, such as growth spurts of supermassive black holes in distant galaxies. “It would be really interesting to see where in the sky the neutrino originated,” says Nepomuk Otte, an associate professor in the School of Physics. Otte is leading a proposed project — with a prototype now being tested in Utah — that would search for Earth-skimming neutrinos by monitoring the atmosphere just above the horizon for flashes of light.

Knitting, the age-old craft of looping and stitching natural fibers into fabrics, is gaining renewed attention for its potential in advanced manufacturing. Beyond creating garments, knitted textiles hold promise for designing wearable electronics and soft robotics – structures that need to move and bend flexibly. A team of physicists from the Georgia Institute of Technology has taken the technical know-how of knitting and added a mathematical foundation to it. Led by Elisabetta Matsumoto, associate professor in the School of Physics, and Krishma Singal, a graduate researcher in Matsumoto’s lab, the team used experiments and simulations to quantify and predict how knitted fabric responses can be programmed. 2024-06-20T00:00:00-04:00

A group of researchers at the Georgia Institute of Technology have created the world’s first functional semiconductor made from graphene, a development that could lead to advanced electronic devices and quantum computing applications. Seen as the building block of electronic devices, semiconductors are essential for communications, computing, healthcare, military systems, transportation and countless other applications. Semiconductors are typically made from silicon, but this material is reaching its limit in the face of increasingly faster computing and smaller electronic devices, according to the Georgia Tech research team who published their findings in Nature earlier this year. In a drive to find a viable alternative to silicon, Walter de Heer, Regents' Professor in the School of Physics, led a team of researchers based in Atlanta, Georgia and Tianjin, China to produce a graphene semiconductor that is compatible with microelectronics processing methods.
