Phys.org / Watching the in situ hydrogen diffusion dynamics in magnesium on the nanoscale
Switchable materials that have extreme material contrast and short switching times with negligible degradation can contribute to active plasmonic and nanophotonic systems. In order to understand their supreme properties, ...
Phys.org / Hybrid multi-chip assembly of optical communication engines via 3-D nanolithography
Three-dimensional (3-D) nanoprinting of freeform optical waveguides also known as photonic wire bonding can efficiently couple between photonic chips to greatly simplify optical system assembly. The shape and trajectory of ...
Phys.org / Cation-induced shape programming and morphing in protein-based hydrogels
Smart materials or advanced materials that can memorize a temporary shape and morph in response to a stimulus can revolutionize medicine and robotics. In a new study now on Science Advances, Luai R. Khoury and a research ...
Phys.org / Pulse-driven robot: Motion via solitary waves
Scientists have recently explored the unique properties of nonlinear waves to facilitate a wide range of applications including impact mitigation, asymmetric transmission, switching and focusing. In a new study now published ...
Phys.org / Finite-temperature violation of the anomalous transverse Wiedemann-Franz law
According to the Wiedemann-Franz (WF) law, the electrical conductivity of a metal is linked to its thermal counterpart, provided that the heat carried by the phonons is negligible and the electrons do not suffer inelastic ...
Phys.org / Exciton resonance tuning of an atomically thin lens
Since the development of diffractive optical elements in the 1970s, researchers have increasingly uncovered sophisticated fundamental principles of optics to replace the existing bulky optical elements with thin and lightweight ...
Phys.org / A new solvent system: Hydrothermal molten salt
In a new report on Science Advances, T. Voisin and a research team in the Scientific Research National Center and the Institute of Technology and Energy Management in France, proposed a new solvent system. The hydrothermal ...
Phys.org / Molecular engineering metal coordination interactions for strong, tough, fast-recovery hydrogels
Load bearing tissues such as muscles and cartilages typically show high elasticity, toughness and fast recovery rates. However, combining such mechanical properties in the lab to build synthetic biomaterials is fundamentally ...
Phys.org / Porous carbon nanofibers demonstrate exceptional capacitive deionization
Capacitive deionization (CDI) is energetically favorable to deionize water, but existing methods are limited by their desalination capacities and time-consuming cycles due to insufficient ion-accessible surfaces and slow ...
Phys.org / Highly sensitive nanosensor detects subtle potassium changes in the brain
Researchers have developed a number of potassium ion (K+) probes to detect fluctuating K+ concentrations during a variety of biological processes. However, such probes are not sensitive enough to detect physiological fluctuations ...
Phys.org / The surface stress of biomedical silicones is a stimulant of cellular response
Silicones are commonly used in the field of medicine to lubricate syringes, encapsulate medical devices, and develop surgical implants. Although the material is generally viewed as relatively inert to cells, they can trigger ...
Phys.org / A robust, sensitive thin-film X-ray detector using 2-D layered perovskite diodes
In a new report on Science Advances, Hsinhan Tsai and a research team in materials, nanotechnology, nuclear engineering and X-ray science at the Los Alamos National Laboratory and the Argonne National Laboratory in the U.S. ...
Phys.org / Computational origami: A universal method to wrap 3-D curved surfaces with nonstretchable materials
The counterintuitive question on how to wrap a curved spherical surface using conventionally stiff and non-stretchable or brittle materials, forms the basis of this study. To answer the question, Yu-Ki Lee and a research ...
Phys.org / Quantum computation solves an old enigma: Finding the vibrational states of magnesium dimer
High vibrational states of the Magnesium dimer (Mg2) are an important system in studies of fundamental physics, although they have eluded experimental characterization for half a century. Experimental physicists have so far ...
Phys.org / Sliding walls – a new paradigm for microfluidic devices
A research team recently developed "sliding walls" as a new technique for fluid control in microfluidic devices, allowing semi-rigid or rigid walls to slide inside a microfluidic chip. In a new report now on Nature: Microsystems ...
