Phys.org / Investigating the dynamics of nanoparticle formation from a precursor at atomic resolution
A key to materials synthesis is the ability to control the process of reduction kinetics and nucleation (phase transition) in materials. Understanding the reduction dynamics during the initial stage of material synthesis ...
Tech Xplore / Adaptive locomotion of artificial microswimmers
Bacteria display remarkable plasticity by exploiting mechanics in response to locally changing physical and chemical conditions. Compliant structures usually assist their taxis behavior to navigate inside complex and structured ...
Phys.org / Nonlinear integrated quantum electro-optic circuits
Physicists envision that the future of quantum computation networks will contain scalable, monolithic circuits, which include advanced functionalities on a single physical substrate. While substantial progress has already ...
Phys.org / Rapid and continuous 3-D printing with light
Three-dimensional (3-D) printing, also known as additive manufacturing (AM), can transform a material layer by layer to build an object of interest. 3-D printing is not a new concept, since stereolithography printers have ...
Medical Xpress / Elastronics—hydrogel-based microelectronics for localized low-voltage neuromodulation
Implantable neuromodulation devices such as deep brain stimulators and vagus nerve stimulators, are widely used to treat neurological diseases. Most devices are composed of rigid probes that limit spatial resolution and increase ...
Phys.org / 3-D culturing hepatocytes on a liver-on-a-chip device
Liver-on-a-chip cell culture devices are attractive biomimetic models in drug discovery, toxicology and tissue engineering research. To maintain specific liver cell functions on a chip in the lab, adequate cell types and ...
Phys.org / Extracting functional mitochondria using microfluidics devices
Mitochondria are dynamic, bioenergetic intracellular organelles, responsible for energy production via ATP production during respiration. They are involved in key cellular metabolic tasks that regulate vital physiological ...
Phys.org / Three-dimensional femtosecond laser nanolithography of crystals
Optical properties of materials are based on their chemistry and the inherent subwavelength architecture, although the latter remains to be characterized in depth. Photonic crystals and metamaterials have proven this by providing ...
Phys.org / Optoacoustic microscopy at multiple discrete frequencies
Optoacoustic imaging powered by short bursts of continuous wave (CW) lasers can stimulate the emission of ultrasound waves inside an animal or in human subjects. The method can noninvasively capture blood flow and produce ...
Phys.org / Rovibrational quantum state resolution of the C60 fullerene
A central objective of chemical and molecular physics is to understand molecules as quantum mechanical systems. The complex internal dynamics of such systems evolve across wide energy and time scales, exhibited by a variety ...
Phys.org / The Prickle1 gene regulates the differentiation of frontal bone osteoblasts in a new animal model
A mechanically compromised skull can result from enlarged fontanelles and smaller frontal bones due to defective migration and differentiation of osteoblasts in the skull primordia (developing skull). The Wnt/Planar cell ...
Phys.org / Glassy carbon microneedles: A new transdermal drug delivery device
Microneedles are designed to infuse medications transdermally (through the skin) and relatively painlessly during clinical applications. In a recent study, Richa Mishra and her colleagues developed a new technique to convert ...
Phys.org / Reactive optical matter: Light-induced motion
Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...
Phys.org / Nucleus-specific X-ray stain for 3-D virtual histology
Histology is used to identify structural details of tissue at the microscale in the pathology lab, but analyses remain two-dimensional (2D) as they are limited to the same plane. Nondestructive 3D technologies including X-ray ...
Phys.org / Electronically programmable photonic molecule
Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. Artificial atom-like and molecule-like systems were previously demonstrated to regulate light ...
