Rechargeable potassium metal batteries are promising energy storage devices with potentially high energy density and markedly low cost. However, eliminating dendrite growth and achieving a stable electrode/electrolyte interface are the key challenges to tackle. Herein, a novel "quasi-liquid" potassium-sodium alloy (KNA) anode comprising only 3.5 wt% sodium (KNA-3.5) is reported, which exhibits outstanding elect...

While scholars and activists often advocate using the term ‘sex worker’ in preference to prostitute, in my research I found that female prostitutes in the Pearl River Delta area, south China, do not like to be addressed as such, and prefer the title xiaojie in Chinese. ‘Sex worker’ generalises the heterogeneity of meanings these women identify and attribute to what they do; it does not capture the complex cultu...
