Phys.org / Water, water everywhere: How UV irradiation reversibly switches graphene between hydrophobic and hydrophilic states
(Phys.org) —Scientists have long observed that the wettability of graphene – an essentially two-dimensional crystalline allotrope of carbon that it interacts oddly with light and with other materials – can be reversed between ...
Phys.org / Flatland, we hardly knew ye: Unique 1-D metasurface acts as polarized beam splitter, allows novel form of holography
(Phys.org) —Traditional three-dimensional (3-D) plasmonic metamaterials with metallic structures – artificial materials that exploit coherent delocalized electron oscillations known as surface plasmons produced from the interaction ...
Phys.org / Serious security: Device-Independent Quantum Key Distribution guards against the most general attacks
The Holy Grail of quantum cryptography – beyond delivering security that cannot be classically achieved – is guaranteeing unconditional security when the untrusted quantum devices are involved. While this goal has been studied ...
Phys.org / Superposition revisited: Proposed resolution of double-slit experiment paradox using Feynman path integral formalism
(Phys.org) —The Schrödinger's Cat thought experiment, published in 1926 by Erwin Schrödinger, may be the most widely-known metaphorical explanation of quantum superposition and collapse. (Superposition is a fundamental principle ...
Phys.org / Now hear this: Simple fluid waveguide performs spectral analysis in a manner similar to the cochlea
(Phys.org) —Within the mammalian inner ear, or cochlea, a remarkable but and long-debated phenomenon occurs: As they move from the base of the cochlea to its apex, traveling fluid waves – that is, surface waves, in which ...
Medical Xpress / Diminutive decoys: Membrane-cloaked nanoparticles disrupt antibody-mediated autoimmune diseases
(Medical Xpress)—What do rheumatoid arthritis, type I diabetes, myasthenia gravis, multiple sclerosis, rheumatic heart disease, and narcolepsy have in common? All of these (and many other) apparently unrelated disorders are ...
Phys.org / Nanocontainers for nanocargo: Delivering genes and proteins for cellular imaging, genetic medicine and cancer therapy
(Phys.org) —By loading any specific protein and nucleic acid into an icosahedral phage T4 capsid-based nanoparticle, the resulting cell delivery vehicle's ligands can bind to the surface of specific target tissues to deliver ...
Phys.org / Step lightly: All-optical transistor triggered by single photon promises advances in quantum applications
(Phys.org) —Optical transistors and switches are fundamental in both classical and quantum optical information processing. A key objective in optics research is determining and developing the structural and performance limits ...
Medical Xpress / Medicinal GPS: DNA nanotechnology-based approach allows injected drugs to find tumor sites
(Medical Xpress)—Current therapies for cancer, wound healing, inflammation, and many other diseases – as well as protocols for drug reloading of vascular grafts and stents – often rely on so-called drug delivery depots, which ...
Phys.org / Quantum meets classical: Qubit fabricated with integrated micromagnet increases speed of quantum manipulation in silicon
(Phys.org) —The ubiquitous classical digital computer encodes data in bits (a portmanteau of binary and digits) in either a 0 or 1 state. On the other hand, while a quantum computer also uses 0/1 data representation, these ...
Medical Xpress / Fit to a T-cell: Conformal hydrogel coating could lead to immunosuppression-free islets of Langerhans transplantation
(Medical Xpress)—Type 1 diabetes is a chronic autoimmune disease in which viral infection1,2, genetics and environmental factors conspire to impact the immune system's T-cells, which then attack and destroy the pancreatic ...
Phys.org / Tiny magnets, huge fields: Nanoscale ferromagnetic electrodes create chemical equivalent of solid-state spin valve
In the study of ways to determine the position of and manipulate magnetic nanoparticles – a capability that would benefit a wide range of applications – there's good news and bad: While a magnetic gradient force field (a ...
Medical Xpress / Promising proteins: Scientists develop new drug discovery tool using spectroscopy and simulation
(Medical Xpress)—In the ongoing quest to design new beneficial molecules or identify potential drugs catalogued in pharmaceutically databases, a critical requirement is determining how a ligand (typically a modulator, or ...
Phys.org / Of catalysts and chirality: Highly-selective growth of structure-specific single-walled carbon nanotubes
(Phys.org) —Carbon – the chemical basis of all known life and an element known as far back as the 8th century BC – exists in a range of forms, or allotropes, with remarkably diverse properties. (Diamond, for example, is transparent ...
Phys.org / Particle, meet wave: Optical qubit technique squeezes photons to bridge discrete and continuous quantum regimes
(Phys.org) —While quantum states are typically referred to as particles or waves, this is not actually the case. Rather, quantum states have complementary discrete particlelike and continuous wavelike properties that emerge ...
