Due to the nature of their material properties, Calcium Fluoride (CaF2), Magnesium Fluoride (MgF2), and Potassium Dihydrogen Phosphate (KDP) are widely used for industrial purposes. A better understanding of the mechanical properties of these materials is of technological and scientific importance. The indentation nano-mechanical response of CaF2 (cubic), MgF2 (tetragonal), and KDP (tetragonal)...

A new optical system has recently been developed that enables infrared images to be obtained with a pixel resolution of 1 micron on a bench-top instrument using a thermal source. We present here imaging data from two contrasting cellular systems that represent different challenges. Renal carcinoma cells cytospun onto CaF2 have a largely rounded morphology and thus suffer from strong resonant Mi...

Low-water soluble metal fluorides such as magnesium fluoride (MgF2) and calcium (CaF2) were evaluated for decay protection of wood. Initially, the biocidal efficacy nano (NMFs) against wood destroying fungi was assessed with an in-vitro agar test. The results from test showed that medium containing MgF2 CaF2 more efficient in preventing fungal than stand-alone or CaF2. These fluorides, their na...

A novel electrochemical cell based on a CaF2 solid-state electrolyte has been developed to measure the electromotive force (emf) of binary alkaline earth-liquid metal alloys as functions of both composition and temperature in order to acquire thermodynamic data. The cell consists of a chemically stable solid-state CaF2-AF2 electrolyte (where A is the alkaline-earth element such as Ca, Sr, or Ba...

For many amorphizable insulators (silicates, garnets, etc.) track observations by different techniques give coherent results concerning the track size at the surface and in the bulk [1, 2]. The situation is quite different for ionic crystals. Their strong ionic binding structure prevents amorphization, and under ion irradiation they respond by a complex damage mechanism. To date, there exists a...

Oxypnictide thin film growth by pulsed laser deposition (PLD) is one of many insufficiently resolved issues in the research of iron-based superconductors. Here we report on the successful realization of superconducting SmO1-xFxFeAs oxypnictide thin film growth by in-situ PLD on CaF2 (fluorite) substrates. CaF2 acts as fluorine supplier by diffusion and thus enables superconducting oxypnictide t...

The scintillation efficiency (quenching factor) of fluorine and calcium nuclei recoiling in a CaF2(Eu) crystal was measured in an energy region relevant to dark matter searches. The recoiling nuclei were obtained via the 19F(n,n’) and 40Ca(n,n’) reactions, where the neutron beam was provided via the d(d,n)3He reaction. The quenching factor of F and Ca nuclei in the CaF2(Eu) crystal was found to...

Over the last six years, Caltech and AccSys Technology, Inc . have developed fast calibration techniques by using a pulsed proton beam from a radio-frequency quadrupole (RFQ) accelerator. The RFQ beam bombards a lithium (Li) or calcium fluoride (CaF2) target permanently installed in an experiment . Radiative capture of the proton yields a flux of single 17 .6 MeV photons from a Li target or sho...

We model the main characteristics of metalinsulator-silicon field-effect transistors (MISFETs) with different gate insulators using the carrier energy distribution function calculated with a Spherical Harmonics Expansion method. In addition to standard devices with Silicon Dioxide or Oxynitride we study a hypothetical MISFET with a rather new crystalline dielectric-Calcium Fluoride. The real ph...

The transverse NMR decays of 129Xe in polycrystalline xenon were recently shown to have a universal property: in the long-time regime these decays all converge to the same sinusoidally modulated exponential function irrespective of the initial transverse spin configuration prepared by a sequence of one or more radio frequency pulses. The present work constitutes a more comprehensive survey of t...
