SuperHydrophobic Surface Fabrication The research plan must include the following: I. Statement of the Problem/s: This study aims to Specifically answer these questions: 1. What chemicals or substances would be effective to use? 2. Where else can we apply the monolayer‚ other than plastic‚ using the same procedures? 3. How long will this effect last? 4. What liquids can it repel besides water? II. Hypothesis: a. There is a significant difference in the results using varied

only to Van der Waals forces that operate by induced polarity in non-polar molecules. Cohesion‚ along with adhesion (attraction between unlike molecules)‚ helps explain phenomena such as meniscus‚ surface tension and capillary action. Mercury in a glass flask is a good example of the effects of the ratio between cohesive and adhesive forces. Because of its high cohesion and low adhesion to the glass‚ mercury does not spread out to cover the bottom of the flask ‚ and if enough is placed in the flask

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy

Microsoft’s Surface Pro laptop-in-disguise1 tablet is no different‚ a “flawed”2 device which has seen improvements to its design and structure over the past few years making it slowly approach perfection. Microsoft’s Surface Pro is one of the newer innovative devices that was initially introduced in February 20133 and has seen a much shorter succession cycle than that of any other popular tablet manufacturer‚ namely Apple. Adoption rate was not at its best with the initial introduction of the Surface Pro

Surface Tension My problem was to find out how to test or measure surface tension. I think the reason of some of the force in surface tension is cohesion and gravity. Surface Tension is the condition existing at the free surface of a liquid‚ resembling the properties of an elastic skin under tension. The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the

How Surface Area Affects the Motion of a Falling Object Introduction During this investigation‚ varying surface areas of objects will be explored in a manner observing the motion as they fall. Most predominantly‚ this motion encircles speed. Speed is calculated from the formula below‚ and hence is directly proportionate to time taken when the distance travelled remains a constant. Speed = Distance/Time Surface area is likely to affect the time taken for an object to complete a descent‚ and

Ratio Analysis Memo July 9‚ 2012 Memo To: From: Date: July 9‚ 2012 RE: Kudler Fine Foods ratio analysis One of the things that we will be going over is some of the ratios for Kudler Fine Foods through Liquidity‚ Profitability‚ and solvency ratios. We will look into some of the finding that were found through these ratios and discuss them. One of the things that we found was where Kudler Fine Foods’ position is with these ratios. The first area that we look at is profitability

Adsorption: The accumulation of molecular species at the surface rather than in the bulk of a solid or liquid is termed as adsorption. Adsorbate: The substance which is being adsorbed on the surface of another substance is called adsorbate. Adsorbent: The substance present in bulk‚ on the surface of which adsorption is taking place is called adsorbent. Desorption: The process of removing an
