Summary: This theoretical work analyzes the formation of the meniscus during capillary rise, highlighting that the meniscus volume depends weakly on wettability and strongly on tube diameter. For most liquids, the contribution of the meniscus to the overall volume can be negligible if the inner tube diameter is less than one millimeter, but sphericity of the meniscus may break down for tube diameters greater than a few millimeters.

Summary: By investigating meniscus shapes and capillary rise heights in modified glass capillaries, we are able to control capillary rise by balancing the centrifugal and volumetric forces. This system provides precise control over the propagation speed of the three-phase contact line, making it useful for studying wetting phenomena on surfaces that dynamically change upon fluid contact.

Summary: This study analyzes the shape of a puddle in a plane wedge with a translational symmetry, approximating it as a curve represented as a particular case of Euler's elastica. The shape of the curve is solely determined by a single dimensionless parameter, either the shape factor or the dimensionless puddle height, and can be classified into three types based on the wedge shape, contact angles, material properties, and the puddle size.

Summary: This study proposes a heterogeneous water-infused divergent surface (WIDS) that can effectively transport high-viscosity liquids by reducing viscous drag through its heterogeneous, slippery topological design and generating capillary forces through its heterogeneous wetting distributions. Experimental results show that this heterogeneous design can transport liquids with viscosities exceeding 12,500 mPa s, which is two orders of magnitude higher than current state-of-the-art techniques. Furthermore, this heterogeneous design is applicable to various high-viscosity liquids and can be made flexible, making it promising for applications in systems that require viscous liquid management, such as micropatterning.

Summary: This study investigates the characteristics of the evaporating meniscus of a nanofluid through simulation and exploration. The results show that the inclusion of nanofluid increases overall heat transfer and the thickness of the evaporating meniscus. However, the combined effect of disjoining pressure and wall slip affects this process.

Summary: Researchers have found that the wetting process of water on a surface patterned with a dense array of nanopillars occurs in two stages: first, an ultra-thin precursor water film forms on the surface, and then capillary action by the nanopillars pulls the water, increasing the overall thickness of the water film.

Summary: This review critically summarizes the fundamentals and concepts of various capillary imbibition models within different geometries over the past 100 years. It discusses the applications of these models and proposes a universal model based on dynamic wetting conditions and equivalent cylindrical geometry. Future research is suggested to focus on analyzing corner flow dynamics, wetting fluid snap-off, capillary rise of non-Newtonian fluids, and employing accurate physical simulation methods for capillary-driven flow processes.

Summary: This study examines the association between endorsement of the model minority stereotype by Asian Americans and mental health, and explores the moderating roles of religion and God representation. The findings suggest that both authoritarian and benevolent God representations play a role in moderating this association. This novel integration of the model minority and religiosity literature has promising implications for professionals working with Asian Americans in Christian settings.

Summary: This study investigated the psychological well-being of Canadian arthroplasty surgeons during the peak of the first wave of the COVID-19 pandemic. The results showed that approximately 38% of the surgeons experienced emotional distress and 29% experienced depression. The main factors contributing to psychological morbidity were concerns about loss of income, emotional conflict, and safety worries. However, the majority of surgeons demonstrated insight into the impact of COVID-19 on their emotional health.

Summary: This study retrospectively reviewed 204 patients (220 hips) who underwent elective total hip arthroplasty (THA) between November 2016 and December 2019. The study analyzed templates from 5 different surgeons and compared the accuracy of preoperative digital templating for different stem designs and surgical approaches. The results showed that the accuracy of femoral component size templating was significantly improved with a single-wedge mid-short stem design. The precision of cup sizing was better in the posterior approach group. Accuracy of templating was found to be dependent on the presence of a calibration marker and the stem design.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
