  • Diluting with Equal Capillaries Technique : why the best results ?

    Equal pressures applied to equal capillaries induce equal flows. When equal flows are some from a gas to be diluted and some (the remaining) from a diluting gas, dilution is given by the ratio of integer numbers : the number of capillaries crossed by the gas to be diluted divided by the total capillaries number.  The key for having very low uncertainty in dilution with a "Equal capillaries" ...

  • Is graphene hydrophobic or hydrophilic?

    The National Physical Laboratory's (NPL) Quantum Detection Group has just published research investigating the hydrophobicity of epitaxial graphene, which could be used in the future to better tailor graphene coatings to applications in medicine, electronics and more. Contrary to widely-held beliefs, the findings indicate that graphene's hydrophobicity is strongly thickness-dependent, with ...

  • Refrigerant leak detection is heavily regulated by government agencies

    Refrigerant leak monitoring in refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC-R) equipment is very challenging, even for the most skilled HVAC-R technician. The leak could be well concealed from view in tubing, a system component, or in an operating or safety control component. With the Environmental Protection Agency (EPA) laws documented ...
