When QDs Meet BPLCEs: Visualized Full-Color and Mechanically-Switchable CPL
Full-color CPL is achieved by doping different quantum dots (QDs) into reconfigurable blue phase liquid crystal elastomers (BPLCE). Unlike with CPL in the cholesteric phase, BPLCE induces opposite CPL signal, entirely independent of photonic bandgaps (PBGs) and yielding a higher glum value even without matching between PBGs and emission bands of QDs.
New Technique Lets Scientists Create Resistance-Free Electron Channels
Researchers have taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state – an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics.
Cleaning up environmental contaminants with quantum dot technology
Quantum dot research just won a Nobel Prize, and now, the applications for nontoxic quantum dots are being expanded. One team of researchers has designed carbon- and sulfur-based dots to help clean up the environment. They will present their results at ACS Spring 2024.
Dawn of solid-state quantum networks
This year’s Nobel Prize in Physics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in “the second quantum revolution” — a new age when we are able to manipulate the weirdness of quantum mechanics, including quantum superposition and entanglement.
Lasers trigger magnetism in atomically thin quantum materials
Researchers discovered that light can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electron “spin.” By controlling & aligning electron spin at this level of detail & accuracy, this platform could have applications in quantum computing & simulation.
New class of versatile, high-performance quantum dots primed for medical imaging, quantum computing
A new class of quantum dots deliver a stable stream of single, spectrally tunable infrared photons under ambient conditions and at room temperature, unlike other single photon emitters.
Scientists age quantum dots in a test tube
Researchers from MIPT and the RAS Institute of Problems of Chemical Physics have proposed a simple and convenient way to obtain arbitrarily sized quantum dots required for physical experiments via chemical aging
No losses: Scientists stuff graphene with light
Physicists from MIPT and Vladimir State University, Russia, have achieved a nearly 90% efficiency converting light energy into surface waves on graphene. They relied on a laser-like energy conversion scheme and collective resonances.
Breakthrough quantum-dot transistors create a flexible alternative to conventional electronics
Researchers at Los Alamos National Laboratory and their collaborators from the University of California, Irvine have created fundamental electronic building blocks out of tiny structures known as quantum dots and used them to assemble functional logic circuits.
A Great New Way to Paint 3D-Printed Objects
Rutgers engineers have created a highly effective way to paint complex 3D-printed objects, such as lightweight frames for aircraft and biomedical stents, that could save manufacturers time and money and provide new opportunities to create “smart skins” for printed parts. The findings are published in the journal ACS Applied Materials & Interfaces.
