Study: Machine learning a useful tool for quantum control
In the everyday world, we can perform measurements with nearly unlimited precision. But in the quantum world—the realm of atoms, electrons, photons, and other tiny particles—this becomes much harder. Every measurement made disturbs the object and.....»»
Industry watch: Interdependent industrial ecosystems
We understand that the semiconductor processes upgrade from 90nm to 28nm relies on "copper interconnect" technology. Low dielectric insulators and high dielectric metal gate materials have received much attention. From 28nm to 16/14nm and 10nm, the f.....»»

Novel high-accuracy twist measurement for bi-grid modulation collimator
A research team led by Prof. Yang Jianfeng from the Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences (CAS) recently proposed high-accuracy twist measurement based on the spherical wave Talbot effect for a b.....»»
Creating and studying radioactive molecules advances nuclear structure and fundamental symmetry studies
An international team performed the world's first measurement of how the size of the radium nucleus modifies the structure of molecules containing different radium isotopes. The research used a combination of lasers and ion traps at the Isotope mass.....»»
Quantum phase transition detected on a global scale deep inside the Earth
The interior of the Earth is a mystery, especially at greater depths (> 660 km). Researchers only have seismic tomographic images of this region and, to interpret them, they need to calculate seismic (acoustic) velocities in minerals at high pressure.....»»
Physicists announce the world"s most precise measurement of neutron lifetime

Novel experiment measures neutron skin in calcium
A new high-precision measurement of the neutron skin in doubly magic calcium-48 may help shed light on proton-neutron interactions inside nuclei. This is the first highly robust electroweak measurement of the neutron skin in a medium-weight nucleus......»»
New measurement method enables more precise investigation of ultrafast processes in matter
A team of researchers from Freiburg led by Prof. Dr. Frank Stienkemeier and Dr. Lukas Bruder has succeeded in developing a new measurement method for investigating ultrafast processes in matter. These are processes at the atomic and molecular level t.....»»
New technique speeds measurement of ultrafast pulses
When we look at an object with our eyes, or with a camera, we can automatically gather enough pixels of light at visible wavelengths to have a clear image of what we see......»»
Team proposes microprinting a fiber-tip polymer clamped-beam probe for high-sensitivity nanoforce measurements
The control and measurement of asserted forces on small objects are frequently seen in micromanipulation, material science, and biological and medical applications. Researchers in China have proposed for the first time the microprinting of a novel fi.....»»
First glimpse of hydrodynamic electron flow in 3D materials
Electrons flow through most materials more like a gas than a fluid, meaning they don't interact much with one another. It was long hypothesized that electrons could flow like a fluid, but only recent advances in materials and measurement techniques a.....»»
Graphic "beach ball" representations calculated for U.S. underground nuclear tests can aid monitoring
Researchers at Lawrence Livermore National Laboratory have calculated moment tensors for 130 underground nuclear and 10 chemical test explosions that have taken place at the Nevada National Security test site......»»
Scientists develop a statistical fix for archaeology"s dating problem
Archeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there's never been.....»»
Superconducting nanowire single-photon detectors: Next big thing in blood flow measurement
In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, cerebral blood flow is considered a vital and sensit.....»»
