TL;DR: In this article, a micromechanical torsion oscillator was used to strengthen the limits on new Yukawa forces by determining the Casimir pressure between two gold-coated plates.

TL;DR: In this paper, the authors reported an improved dynamic determination of the Casimir pressure Pexpt between two plane plates obtained using a micromachined torsional oscillator.

TL;DR: The first precise measurement of the Casimir force between dissimilar metals is reported and the results agree to better than 1% in the 0.2-2 micro m range with a theoretical model that takes into account the finite conductivity and roughness of the two metals.

TL;DR: In this article, the authors report new constraints on extra-dimensional models and other physics beyond the standard model based on measurements of the Casimir force between two dissimilar metals for separations in the range $0.2 -1.2 pN.

TL;DR: In this paper, the authors present supplementary information on the recent indirect measurement of the Casimir pressure between two parallel plates using a micromachined oscillator and compare the data with a new theoretical approach to the thermal Casimir force based on the use of the Lifshitz formula, combined with a generalized plasma-like dielectric permittivity.
