Phys.org / Direct 2D-to-3D transformation of pen drawings
Pen drawings can allow simple, inexpensive and intuitive two-dimensional (2D) fabrication. Materials scientists aim to integrate such pen drawings to develop 3D objects. In a new report now published on Science Advances, ...
Phys.org / High-entropy-stabilized chalcogenides with high thermoelectric performance
Thermoelectric technology can generate electricity from waste heat, although their performance can result in a bottleneck for wider applications. Materials scientists can regulate the configurational entropy of a material ...
Phys.org / A bio-inspired mechano-photonic artificial synapse
Multifunctional and diverse artificial neural systems can incorporate multimodal plasticity, memory and supervised learning functions to assist neuromorphic computation. In a new report, Jinran Yu and a research team in nanoenergy, ...
Phys.org / On-chip torsion balance with femtonewton force resolution at room temperature
The torsion balance contains a rigid balance beam suspended by a fine thread as an ancient scientific instrument that continues to form a very sensitive force sensor to date. The force sensitivity is proportional to the lengths ...
Phys.org / Understanding the structural and chemical heterogeneities of surface species at the single-bond limit
Advances in tip-based microscopy in materials science have allowed imaging at angstrom-scale resolution, although the technique does not provide clear characterization of the structural and chemical heterogeneities of surface ...
Phys.org / Plasmonic nanoreactors regulate selective oxidation via energetic electrons and nanoconfined thermal fields
When optimizing catalysis in the lab, product selectivity and conversion efficiency are primary goals for materials scientists. Efficiency and selectivity are often mutually antagonistic, where high selectivity is accompanied ...
Phys.org / A single-molecule electrical approach for amino acid detection and chirality recognition
Analytical chemistry aims to efficiently discriminate between two amino acids. In a new report in Science Advances, Zihao Liu and a research team in Chemistry, Physics, and Materials Science in China and Japan, used a single-molecule ...
Phys.org / Cryo-electron microscopic structure of a proton-activated chloride channel named TMEM206
The transmembrane protein 206 abbreviated as TMEM206 is an evolutionarily conserved chloride channel that underlies the ubiquitously expressed, proton-activated, outwardly rectifying anion currents. In a new report now published ...
Phys.org / Exploring complex graphs using three-dimensional quantum walks of correlated photons
Graph representations can solve complex problems in natural science, as patterns of connectivity can give rise to a magnitude of emergent phenomena. Graph-based approaches are specifically important during quantum communication, ...
Phys.org / Hierarchical mechanical metamaterials offer multiple stable configurations
Multistable mechanical metamaterials are artificial materials whose microarchitecture offers more than two different stable configurations. Existing mechanical metamaterials rely on origami or kirigami-based designs with ...
Phys.org / Evidence of superfluidity in a dipolar supersolid
Superfluidity in liquids and gases can manifest as a reduced moment of inertia (the rotational analog of mass) under slow rotations. Non-classical rotational effects can also be considered in the elusive supersolid phases ...
Phys.org / Do photosynthetic complexes use quantum coherence to increase their efficiency?
In a new report now published on Science Advances, Elinor Zerah Harush and Yonatan Dubi in the departments of chemistry and nanoscale science and technology, at the Ben-Gurion University of the Negev, Israel, discussed a ...
Medical Xpress / Learning hierarchical sequence representations across human cortex and hippocampus
Humans experience sensory input continuously as segmented units of words and events. The ability of the brain to discover regularities is known as statistical learning. This concept can be represented at multiple levels including ...
Phys.org / Nanoshape imprint lithography using molecular dynamics of polymer crosslinking
Nanoscale applications in energy, optics and medicine have enhanced performance with nano-shaped structures. Such architectures can be fabricated at high-throughput beyond the capabilities of advanced optical lithography. ...
Medical Xpress / Wireless, implantable catheter-type oximeter designed for cardiac oxygen saturation
The real-time monitoring of intravascular oxygen levels is important to accurately track the cardiopulmonary health of patients after cardiothoracic surgery. Existing methods use intravascular placement of glass fiber-optic ...
