Your accent metal should compliment the dominant metal. All together there should be a maximum of three finishes all together including your dominant metal. Depending on the size of your space you might only opt for two finishes instead of three. 3. Repeat the metal Finishes You just have take in to consideration placement of your mixtures and hardware. Also the size of your bathroom. And the style of fixtures and hardware you need to put in there. where F b is the buoyant force of the oil in water, ρ o s the density of the oil, V o is the volume of the oil when intrusion occurs and S is the area of the mesh. Separation efficiency assessment of meshes Another way to mix in your metals, is to have the same metal for the faucets and the hardware on the drawers. The contrasting metal this time would be for the lighting fixtures and the mirror. Mixing metals on a budgetCheryan, M. & Rajagopalan, N. Membrane processing of oily streams.

An easy way to put different metals together in the bathroom is looking at the different levels in your bathroom. Dividing the space up this way is a good starting point and keeps things simple. Jagdheesh, R., Diaz, M., Marimuthu, S. & Ocana, J. L. Robust fabrication of μ-patterns with tunable and durable wetting properties: Hydrophilic to ultrahydrophobic via a vacuum process. J. Mater. Chem. A 5, 7125–7136 (2017).The selective surface wetting properties of surfaces are commonly achieved by controlling the morphology and the surface energy through formation of a hierarchical micro-nanostructure and/or tuning of the surface chemistry 16. To functionalize the surfaces, wet and dry methods, including dip coating, sol–gel, surface etching, electrospinning, lithography, chemical vapor deposition, plasma surface modification and radical polymerization, are reported in the literature 11, 13, 17, 18, 19, 20, 21. Among them, atmospheric-pressure plasma-based methods are of major interest for industrial up-scaling. These methods are operating in open-air, generate few wastes, are easily implementable in continuous processes like roll-to-roll systems, are able to rapidly modify large surfaces in a single step, run at low cost as they do not require the use of expensive vacuum equipment and they have low processing temperature, allowing the modification of heat sensitive materials 22. The highly reactive species present in the plasma enable to directly modify the surface of material or to form functional layers 13, 20, 22. Via simple variation of the plasma gas composition, the surface property of meshes and membranes can easily be controlled. These methods were applied to develop oil–water separation devices relying on single functionalized membranes or meshes: Chen et al . reported a 97.5% oil/water separation efficiency using nylon membranes modified by a mm-size atmospheric pressure helium plasma jet to develop superhydrophilic/underwater-superoleophobic surface for water permeation 20. You et al . successfully demonstrated oil collection using a stainless steel mesh functionalized via atmospheric pressure plasma polymerization to develop oleophilic/superhydrophobic surface 13. The dominant metal should be repeated in the space and should be the finish of a main focal point. This could be the mirror on the wall. Or the light pendant or the sink in the bathroom. It should be repeated throughout the space at least in two different places. 2.
