In this short review, I introduce an integrated vision of human hair follicle behavior and describe opposing influences that control hair follicle homeostasis, from morphogenesis to hair cycling. The interdependence and complementary roles of these influences allow us to propose that the hair follicle is a true paradi…

In this paper, a two-dimensional model of a closed metal-hydrogen reactor is presented. The temperature and the pressure temporal evolutions within the reactor as a function of time are reported. In order to determine the parameters to optimize a fast kinetic and optimal heat exchange, impact of the supply pressure, t…
We investigate the dependence of friction forces on normal load in incommensurate micrometer size contacts between atomically smooth single-crystal graphite surfaces under ambient conditions. Our experimental results show that these contacts exhibit superlubricity (super-low friction), which is robust against the appl…
BeO is one of the most common moderator material for neutron moderation; due to its high density, neutron capture cross section and physical-chemical properties that provides usage at elevated temperatures. As it’s known, for various applications in the field of reactor design and neutron capture, reaction cross–secti…
The use of ultrasonic transducers with a central hollow is suggested for improved single-beam acoustical tweezers applications. Within the framework of the Fresnel-Kirchhoff parabolic approximation, a closed-form partial-wave series expansion (PWSE) for the incident velocity potential (or pressure) field is derived fo…
Solid chunks of matter catalyze most of today’s industrial-scale chemical processes. If scientists knew exactly where reactions occur on these catalytic solids, they could customize them to improve the performance of catalysts already in use and help bring new ones to market. By devising a fluorescence microscopy tech…

DNA strands anchored to the surface of nanoparticles allow researchers to assemble the particles into three-dimensional crystalline lattices. Such control allows researchers to make new materials with desirable properties. In two recent studies, independent teams adapted this approach to gain even more control over as…
Kidney disease is known as a silent killer. That’s because the markers physicians look for to diagnose the disease, such as urea and creatinine levels in the blood, often appear normal even when up to 75% of kidney function has been lost. One inexpensive, noninvasive method for imaging kidneys is to use near-infrared…
A combined molecular-beam and quantum-simulation study that explores the catalytic behavior of tiny platinum clusters calls into question a well-established precept regarding the influence of structure on the reactivity of solid catalysts (Nat. Commun. 2016, DOI: 10.1038/ncomms10389). Years of experiments have shown t…

In a world of technologies built on quantum materials, computers will work a million times faster than today’s supercomputers while using a fraction as much energy. Electricity will be generated, transmitted, and used with almost no losses. Smart building materials, fabrics, and electronic devices will change their pr…
