Phys.org / Layer-engineered large-area exfoliation of graphene
Large-scale manufacturing processes that aim to produce two-dimensional materials (2DMs) for industrial applications are based on a competition between quality and productivity. The top-down mechanical cleavage method allows ...
Phys.org / Single-shot 3-D wide-field fluorescence imaging with a computational miniature mesoscope
The online feature cover photograph on Science Advances this week displays fluorescence imaging with a computational miniature mesoscope (CM2). The technique of fluorescence imaging is an essential tool for biologists and ...
Phys.org / Mechanistic basis of oxygen sensitivity in titanium
Titanium is extremely sensitive to small amounts of oxygen, which can lead to markedly decreased ductility of the material. Materials scientists therefore aim to lower the costs of purifying titanium, while avoiding the poisoning ...
Phys.org / Directly observing intracellular nanoparticle formation with nano-computed tomography
It is currently challenging to directly observe the formation of intracellular nanostructures in the lab. In a new report, Miaomiao Zhang and a research team in chemistry, life sciences, medical engineering and science and ...
Phys.org / Tailoring nanocomposite interfaces with graphene to achieve high strength and toughness
The weak interfacial interaction between nanofillers and matrix nanocomposites during materials engineering have caused nanofiller reinforcing effects to be far below the theoretically predicted values. In a new report now ...
Phys.org / Shedding light on moiré excitons: A first-principles perspective
Moiré superlattices that are located within van der Waals (vdW) heterostructures can trap long-lived interlayer excitons to form ordered quantum dot arrays, paving the way for unprecedented optoelectronic and quantum information ...
Phys.org / Microscopy with undetected photons in the mid-infrared region
Microscopy techniques that incorporate mid-infrared (IR) illumination holds tremendous promise across a range of biomedical and industrial applications due to its unique biochemical specificity. However, the method is primarily ...
Phys.org / Layer-cake 2-D superconductivity: Developing clean 2-D superconductivity in a bulk van der Waals superlattice
Materials science has had a profound historical impact on humanity since the advent of the Iron and Bronze ages. Presently, materials scientists are intrigued by a class of materials known as quantum materials, whose electronic ...

Phys.org / Giant electrochemical actuation in a nanoporous silicon-polypyrrole hybrid material
The absence of piezoelectricity in silicon can lead to direct electromechanical applications of the mainstream semiconductor material. The integrated electrical control of silicon mechanics can open new perspectives for on-chip ...
Phys.org / Was the moon magnetized by impact plasmas?
The moon, Mercury and many meteorite parent bodies contain a magnetized crust, which is commonly credited to an ancient core dynamo. A longstanding alternative hypothesis suggests the amplification of the interplanetary magnetic ...
Phys.org / Squeezing light: Developing an integrated nanophotonic device to generate squeezed light
Scientists can generate squeezed light via strongly driven spontaneous four-wave mixing below threshold in silicon nitride microring resonators. The generated light can be characterized with homodyne detection (to extract ...
Phys.org / Achieving invisibility: Cross-wavelength invisibility integrated with invisibility tactics
Invisibility is a superior self-protection strategy of long-standing interest in academia and industry, although the concept is thus far most popularly encountered in science fiction. In a new report on Science Advances, ...
