Physical vapor deposition PHYSICAL METHODS A physical deposition process consists of three steps: 1. Emission of the particles from a source 2. Their transport to the substrate 3. The condensation on the substrate Physical vapor deposition a process by which a thin film of material is deposited on a substrate according to the following sequence of steps: 1) the material to be deposited is converted into vapor by physical means; 2) the vapor is transported across a region of low pressure

Rub & Stub is first restaurant in Europe to fight food waste by using surplus goods from the food industry (Rub & Stub‚ 2015). The restaurant receives food‚ which has been donated from farmers‚ food cooperatives‚ local food stores‚ bakeries‚ and FødevareBanken. The goal is to minimize the amount of food waste‚ therefore they receive food that has the ‘wrong’ size‚ shape or color‚ just food which is close to the ‘best before’ date (Rub & Stub‚ 2015). The food waste issue remains alarming‚ however

The vapor pressure of a liquid is the equilibrium pressure of gas molecules from that liquid (i.e.‚ the results of evaporation) above the liquid itself. A glass of water placed in an open room will evaporate completely (and thus never reach equilibrium); however‚ if a cover is placed on the glass‚ the space above the liquid will eventually contain a constant amount of water vapor. How much water vapor is present depends on the temperature‚ but not on the amount of liquid that is present at equilibrium

Experiment :12 Vapor Pressure and the Heat of Vaporization Nicole Petersen TA: Ryan Dixon 4/16/2013 Purpose: Use experimental techniques to record temperature and volume data for known and unknown compounds. The liquid and gas are going to be at equilibrium. We will also determine the boiling point for the known and unknown. Then use a graph to calculate the slope and then use Clasius- Clapeyron equation to find the heat vaporization. Procedure: Refer to pages 155-167 of Chemistry 1210 General

Vapor Pressure and Enthalpy of Vaporization of Water 1/9/12 Emily Toy Lab Partner: Zack Ronnei Instructor: Ms. Olsen‚ AP Chemistry Purpose: The purpose of this lab is to find the vapor pressure of water at temperatures between 50oC and 80oC. Procedure: 1. Take a10 mL graduated cylinder and fill it with 7 mL of water. 2. Next fill a 1000 mL beaker ¾ full with water. 3. Cover the graduated cylinder by putting your finger on top and place the cylinder in the 1000 mL beaker. Make

It’s a Tuesday. I’m finishing my workout at my neighborhood gym. I walk into the locker room‚ throw my clothes off‚ and head to the showers. The water is warm. I’m feeling like a real go-getter. The endorphins‚ the steam – it’s relaxing. Veeery relaxing. I take a handful of the shower gel that the gym supplies in buckets and start lathering up. I’m making sure things are clean down there. Really‚ really clean. (Not really‚ readers – I’m jerking off. Duh.) So I’m a showerbater; I admit it. I like

it isn’t an alcoholic beverage. With an awesome drink recipe I’m going to show you today‚ no one can even guess that you’re drinking a non-alcoholic beverage. If you’re hosting a baby shower or meet the baby party‚ this Cotton Candy Raspberry Cream Mimosa would be a wonderful choice. The cocktail is very festive‚ with fresh berries and lots of bubbles. One last thing I’d like to mention. Since we’re talking about wine‚ that went through a process of de-alcoholization‚ there is still a tiny amount of
