Absorption of CO2 from a gas mixture containing CO2 and nitrogen by water-based CNT nanofluids in gas–liquid hollow fiber membrane contactor was modeled and solved using COMSOL Multiphysics 5.4. The model assumed partial wetting of the membrane, along with diffusion in the axial and radial directions. In addition, Brownian motion and grazing effects were both considered in the model. The main c...

We consider the thin-film equation $\partial_t h + \partial_y \left(m(h) \partial_y^3 h\right) = 0$ in $\{h > 0\}$ with partial-wetting boundary conditions and inhomogeneous mobility of form $m(h) h^3+\lambda^{3-n}h^n$, where $h \ge is film height, $\lambda slip length, $y denotes lateral variable, $n \in (0,3)$ exponent parameterizing nonlinear condition. The regime implies condition $\partial...

introduction ileal diverticulum is a rare disease that presents with complications such as diverticulitis. case presentation we present an 81-year-old man with partial small bowel obstruction having abdominal pain, nausea, vomiting for 48 hours and a mobile abdominal mass. after ct scan, exploratory laparoscopy and small bowel resection was done with primary anastomosis. conclusions when adhesi...

Microscopy, especially fluorescence microscopy, has proven to be a powerful method for studying biological processes. Unfortunately, some of the same features that make biological membranes powerful (for example, all of the action taking place across a narrow 4nm film) also make it difficult to visualize by fluorescence. Over the past 30 years, numerous tricks have been developed to narrow the ...

Stable, nanometer-thick films are observed to form at the {1120} facets of Bi(2)O(3)-doped ZnO in several bulk-phase stability fields. Electron microscopy shows these surficial films to exhibit some degree of partial order in quenched samples. The equilibrium film thickness, corresponding to the Gibbs excess solute, decreases monotonically with decreasing temperature until vanishing at a dewett...

Wetting of the pore walls of porous templates is a simple and convenient method to prepare nanotubes. Ferroelectric lead zirconate titanate and barium titanate nanotubes were fabricated by wetting of porous silicon templates of polymeric precursors. The ferroand piezoelectric properties of an individual ferroelectric either of a PZT or a BaTiO3 nanotube were electrically characterized by measur...
