Control of capillary flow through porous media has broad practical implications. However, achieving accurate and reliable control of such processes by tuning the pore size or by modification of interface wettability remains challenging. Here we propose that the liquid flow by capillary penetration can be accurately adjusted by tuning the geometry of porous media. Methodologies: On the basis of Darcy’s law, a general framework is proposed to facilitate the control of capillary flow in porous systems by tailoring the geometric shape of porous structures. A numerical simulation approach based on finite element method is also employed to validate the theoretical prediction. Findings: A basic capillary component with a tunable velocity gradient is designed according to the proposed framework. By using the basic component, two functional capillary elements, namely, (i) flow accelerator and (ii) flow resistor, are demonstrated. Then, multi-functional fluidic devices with controllable capillary flow are realized by assembling the designed capillary elements. All the theoretical designs are validated by numerical simulations. Finally, it is shown that the proposed concept can be extended to three-dimensional design of porous media

Jacobin, Januari 2024: Om tonårstidningen Teen Vogue som läses av mer än 8 miljoner: "Även om de exakta siffrorna är omtvistade är en sak helt klar: långt fler vuxna - mestadels millenniegenerationen, även när vi är på väg in i medelåldern - läser tonårstidningen som kallar sig "den unga människans guide till att erövra (och rädda) världen" än tonåringar."
"Most damningly, just 1.7 percent of their May 2018 audience was 17 or younger. Only 2.6 percent were 18 to 24 years old. At the absolute most generous estimate, in Teen Vogue’s digital audience — the only audience they still have after they shelved their print edition with a final copy featuring Hillary Clinton on the cover — 1 in 20 readers is an actual teenager."
