TL;DR: This work describes the emission of highly collimated, spatially coherent X-rays, at a wavelength of about 1 nanometre and at photon energies extending to 1.3 kiloelectronvolts, from atoms that have been ionized by a 5-femtosecond laser pulse.

TL;DR: In this paper, the single-atom quantum theory of high-order harmonic generation combined with Maxwell's wave equation provides a satisfactory account for the experimental observations, and the sub-10-fs laser pulse duration was found to be crucial for generating radiation with the highest photon energies at the low ( $l 0.5\mathrm{mJ}$) pump energy levels used in the experiments.

TL;DR: It is shown for the first time that there is a differential accumulation of the trace elements Zn, Pb and Sr in BSUs of human bone indicating different mechanisms of accumulation.

TL;DR: Analysis of bone mineralization density distribution (BMDD), strontium (Sr) concentration, collagen cross‐link ratio, and indentation modulus provide evidence that the investigated bone quality determinants at tissue level were preserved in postmenopausal osteoporotic women after 3‐year treatment with SrR per day plus calcium and vitamin D.

TL;DR: A review of advances in the XRF group of techniques published approximately between April 2015 and March 2016 can be found in this paper, where a bench top TXRF spectrometer for the measurement of the elements from carbon to uranium is described that offers achievable detection limits that range from ng g−1 to μg g −1.
