Abstract The chirality-asymmetry macroscopic force mediated by light pseudoscalar particles between $\alpha $-quartz and some achiral matter is studied. If this force between achiral source mass and $\alpha $-quartz with some chirality is attractive, it will become repulsive when the chirality of the $\alpha $-quartz crystal is changed. According to the tested limits of the coupling constant $g_{\rm s} g_{\rm p} / \hbar c < 1.5\times 10^{ - 24}$ at the Compton wavelength $\lambda = 10^{ - 3}$\,m, the force ($F$) between a $0.08\times 0.08\times 0.002$\,m$^{3}$ block of $\alpha $-quartz and a $0.08\times 0.08\times 0.01$\,m$^{3}$ copper block with a separation being $0.5\times 10^{ - 3}\,\mbox{m}$ in between, is estimated from the published data at less than $4.64\times 10^{ - 24}\,\mbox{N}$, i.e. $F < 4.64\times 10^{ - 24}\,\mbox{N}$.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
