Effective decrease of photoelectric emission threshold from gold plated surfaces
TL;DR: A working model, designed to allow accurate simulation of any experimental configuration, is proposed for photoelectric emission from gold surfaces, and results were obtained in a vacuum system with a baseline pressure of ∼10-7 mbar at room temperature.

TL;DR: In this article, two novel methods, tested by LISA Pathfinder, were used to measure the gravitational constant G for the first time in space, using electrostatic suspension forces to measure a change in acceleration due to a displaced source mass.

TL;DR: In this article, the authors presented sensitivity projections to several low-energy signals of the complementary electron recoil signal type: 1) an effective neutrino magnetic moment and 2) a effective neutrer millicharge, both for pp-chain solar neutrinos, 3) an axion flux generated by the Sun, 4) axion-like particles forming the galactic dark matter, 5) hidden photons, 6) mirror dark matter and 7) leptophilic dark matter.

TL;DR: In this paper, a method for calibration and assessment of the linearity of response of an array of photomultiplier tubes is described. But this method does not require knowledge of the photOMultipliers single photoelectron response model and uses science data directly, thus eliminating the need for dedicated data sets.
