We review measurements of the Boltzmann constant, k, the value of which is soon to be fixed at exactly 1.380 649 × 10 − 23 J⋅K−1 for the future revised Systeme international of units. In addition to a description of the theoretical background

The French National Metrology Institute LNE-LCM has developed a new in situ electrical calibration system which is integrated into a heat flux Calvet calorimeter in order to perform accurate and reliable measurements of enthalpy of fusion from 23 °C

The Boltzmann constant k has been determined from a measurement of the speed of sound in helium gas in a quasi-spherical resonator (volume 0.5 l) maintained at a temperature close to the triple point of water (273.16 K). The acoustic velocity c is de

The sensitivity of a force sensor based on photo-elastic effect in a monolithic Nd- YAG laser depends strongly on the geometrical shape and dimensions of the laser medium. The theoretical predictions of sensitivity are in good agreement with first re

The SI unit of temperature will soon be redefined in terms of a fixed value of the Boltzmann constant k derived from an ensemble of measurements worldwide. We report on a new determination of k using acoustic thermometry of helium-4 gas in a 3-litre

The unit of force is connected to the international prototype of the kilogramme, unit of mass in the international system of units (SI), via dead weight machines using calibrated masses. However, forces below 10 μ N, ubiquitous in nature and in some

A direct application of digital in-line holography to liquid droplets dispersed in a continuous liquid phase is described. The droplet size imposes a regime of intermediate-field diffraction that has been little explored to date. Acquired diffraction
