Phys.org / Giant gate-tunable bandgap renormalization and excitonic effects in a 2-D semiconductor
Investigating the remarkable excitonic effects in two-dimensional (2-D) semiconductors and controlling their exciton binding energies can unlock the full potential of 2-D materials for future applications in photonic and ...
Tech Xplore / Topology optimization and 3-D printing multimaterial magnetic actuators and displays
In materials science and applied physics, researchers expect actuation systems to perform similarly to natural phenomena. As a classic example, scientists proposed to engineer bioinspired materials that mimicked the camouflage ...
Phys.org / Seeing smaller through cells: A natural single-cell biomagnifier for subwavelength imaging
Optical microscopes and tweezers can image and manipulate objects at the microscale for applications in cellular and molecular biology. The optical resolution is, however, hampered by the diffraction limit and therefore both ...
Phys.org / Bioinspired MXene-based actuators for programmable smart devices
During photosynthesis, natural leaves with elaborate architectures and functional components can harvest and convert solar energy into chemical fuels that are converted into energy. The biological energy production has provided ...
Tech Xplore / Inspired by water lilies: A hierarchical design for solar evaporation of high salinity brine
Interfacial solar vapor generation has great potential for desalination and wastewater treatment with high energy conversion efficacy. High water evaporation rates cannot be maintained using existing techniques, however, ...
Phys.org / Shape-encoded dynamic assembly of mobile micromachines
Field-directed and self-propelled colloidal assembly can be used to build micromachines to perform complex motions and functions, although their integration as heterogenous components with specified structures, dynamics and ...
Phys.org / Creating two-dimensional layered Zintl phase by dimensional manipulation of the crystal structure
The discovery of new families of two-dimensional (2-D) layered materials beyond graphene has always attracted great attention, but it remains challenging to artificially recreate the honeycomb atomic lattice structure with ...
Phys.org / Osteoblastic lysosome plays a central role in mineralization
Mineralization is mediated by osteoblasts, which secrete mineral precursors through matrix vesicles (MVs) as a fundamental process in vertebrates. The vesicles are calcium and phosphate rich, containing organic materials ...
Phys.org / MEMS-in-the-lens architecture for laser scanning microscopy
Laser-scanning microscopes can be miniaturized to image microenvironments in vivo via inclusion inside optical micromechanical system (MEMS) devices to replace the existing larger components. Multifunctional active optical ...
Medical Xpress / Computing hubs in the hippocampus and cortex
Neural computation occurs in large neural networks within dynamic brain states, yet it remains poorly understood if the functions are performed by a specific subset of neurons or if they occurred in specific, dynamic regions. ...
Phys.org / Isolating intact bacteria from blood using a microfluidic monolith device
Emerging single-cell diagnostics rely on the potential to rapidly and efficiently isolate bacteria from complex biological matrices. In a recent study now published in Microsystems and Nanoengineering, Jung Y. Han and colleagues ...
Phys.org / Multifaceted design optimization for superomniphobic surfaces
In materials science, surfaces that strongly repel low surface tension liquids are classified 'superoleophobic," while high surface tension liquid repellants are 'superhydrophobic' and surfaces that display both characteristics ...
Phys.org / Printing liquid metals in three-dimensional structures
In a recent study on materials science and nanomedicine, Young-Geun Park and co-workers at the departments of Nanoscience, Nanomedicine and Materials Science and Engineering in the Republic of Korea developed an unconventional ...
Phys.org / Low-temperature aqueous alteration of Martian zircon during the late Amazonian period
Many accounts at present support the presence of liquid water on Mars, where hydrated minerals testify to past processes of aqueous weathering in Martian meteorites such as NWA 7533/7034. Planetary scientists aim to estimate ...
Phys.org / Designing light-harvesting organic semiconductor microcrystals with wavelength-tunable lasers
Organic solid-state lasers are essential for photonic applications, but current-driven lasers are a great challenge to develop in applied physics and materials science. While it is possible to create charge transfer complexes ...
