Phys.org / Climbing droplets driven by mechanowetting on transverse waves
Modern applications use self-cleaning strategies and digital microfluids to control individual droplets of fluids on flat surfaces but existing techniques are limited by the side-effects of high electric fields and high temperatures. ...
Phys.org / Digitally programmable perovskite nanowire-block copolymer composites
One-dimensional nanomaterials with highly anisotropic optoelectronic properties can be used within energy harvesting applications, flexible electronics and biomedical imaging devices. In materials science and nanotechnology, ...
Phys.org / Inducing an osteoarthritic (OA) phenotype in a cartilage-on-a-chip (COC) model
In an aging population, the social impact of osteoarthritis (OA) can dramatically increase to become the most common musculoskeletal disease. However, at present, therapies are limited to palliative treatments or surgical ...
Phys.org / Raising fluid walls around living cells
Cell culture plates that are in everyday use in biology can be effectively transformed into microfluidic devices, opening paths for biologists to miniaturize cell-based workflows. In a recent report, Ph.D. researcher Cristian ...
Phys.org / Visualizing a quantum crystal: Imaging the electronic Wigner crystal in 1-D
When electrons that repel each other are confined to a small space, they can form an ordered crystalline state known as a Wigner crystal. Observing the fragile crystal is tricky, since it requires extreme conditions including ...
Phys.org / Bioinspired Materials—Graphene-enabled nickel composites
Bioinspired engineering strategies rely on achieving the combined biological properties of strength and toughness inherent in nature. Tissue engineers and materials scientists therefore aim to construct intelligent, hierarchical ...
Phys.org / Biotechnology: Using wireless power to light up tiny neural stimulators
""Implantable optical devices that target neurons can be improved using miniature coils smaller than a grain of rice using optogenetic technology. Scientists can propagate pulses of light using the method to turn protein ...
Phys.org / Polarization-encryption based data storage in 3-D Janus plasmonic helical nanoapertures
Helical plasmonic nanostructures have attracted considerable attention in materials science and chemistry due to their inherent optical chirality. In a new report, Yang Chen and a research team in the department of Mechanical ...
Phys.org / Specific ion effects directed noble metal aerogels
Noble metal foams (NMFs) are a new class of functional materials that contain both noble metals and monolithic porous materials for impressive multi prospects in materials science and multidisciplinary fields. In a recent ...
Phys.org / Quick liquid packaging: Encasing water silhouettes in 3-D polymer membranes for lab-in-a-drop experiments
The ability to confine water in an enclosed compartment without directly manipulating it or using rigid containers is an attractive possibility. In a recent study, Sara Coppola and an interdisciplinary research team in the ...
Phys.org / Atomic engineering with electric irradiation
Atomic engineering can selectively induce specific dynamics on single atoms followed by combined steps to form large-scale assemblies thereafter. In a new study now published in Science Advances, Cong Su and an international, ...
Phys.org / On-demand, photonic entanglement synthesizer
Quantum information protocols are based on a variety of entanglement modes such as Einstein-Podolsky-Rosen (EPR), Greenberger-Horne-Zeilinger (GHZ) and other cluster states. For on-demand preparation, these states can be ...
Medical Xpress / Engineering B cells to express pathogen-specific antibodies to protect against infection
Antibodies are currently in use to treat diseases that range from cancer to autoimmunity and are usually administered to patients in multiple doses, much like medical drugs. However, the production and storage of antibodies ...
Phys.org / Nanoscopic protein motion on a live cell membrane
Cellular functions are dictated by the intricate motion of proteins in membranes that span across a scale of nanometers to micrometers, within a time-frame of microseconds to minutes. However, this rich parameter of space ...
Phys.org / 3-D grayscale digital light printing (g-DLP) highly functionally graded materials (FGM)
Three-dimensional (3-D) printing or additive manufacture (AM) is a popular technique that has presently attracted tremendous attention as a promising method to revolutionize design and manufacture. Researchers have expanded ...
