Experimental investigation of drag coefficient of free-falling deformable liquid gallium droplet

Optical switch using a deformable liquid droplet.

An optical switch based on a deformable liquid droplet is demonstrated. The device consists of a clear liquid droplet surrounded by a black liquid. In the voltage-off state, the incident light is absorbed by the black liquid. As the voltage increases, the dielectric force reshapes the droplet by uplifting its dome. As the dome touches the top substrate, a clear channel is opened, allowing the i...

In situ Microscopy Studies of Liquid Gallium Droplet Dynamics

Liquid metals such as gallium and related alloys are promising as hydrogenand energy-storage materials [1], for battery electrodes [2], in mercury-free thermometry [3], as plasmonic coupling materials [4], in electrical switches [5], as conductors in ultra-stretchable wires [6], and as catalysts for the growth of nanowires [7–8], and graphene [9–10]. This is largely due to their low vapor press...

Imbibition of a liquid droplet on a deformable porous substrate

We consider the imbibition of a liquid droplet into a deformable porous substrate. The liquid in the droplet is imbibed due to capillary suction in an initially dry and undeformed substrate. Deformation of the substrate occurs as the liquid fills the pore space. In our model, a pressure gradient in the liquid across the developing wet substrate region induces a stress gradient in the solid matr...

investigation of thermal comfort properties of woven sport fabric using blend of estabragh fibers

امروزه لباس در نظر ورزشکاران و کسانی که برای اوقات فراغت خود و یا برای رسیدن به اندامی متعادل، ورزش می کنند؛ بسیار با اهمیت است. احساس مطلوب از لباس در زمره خصوصیات راحتی پوشش می باشد. خصوصیات انتقال رطوبت لباس، در ارزیابی راحتی حسی و حرارتی منسوجات تولید شده از آن ها بسیار مهم است. هدف از این تحقیق، معرفی پارچه جدید است که متشکل از الیاف استبرق با خواص منحصر به فرد می باشد. استبرق لیف طبیعی تو...
