Sunday January 22nd, 2017 14:25 Dry ice extraction experiment and a possessed test tube

This video is just a experiement me and my friends did for our Analytical Chem experiment at Kwantlen Polytechnic Uinversity. What I wanted to show was some of the stuff that happens in a chem lab to people or students who havn’t seen stuff in a lab before. In the first part of the video, i want to show what happens when you drop a piece of dry ice in a beaker full of hot water. As everyone can see, it immediatly sublimes. In the second part of the video, we are performing the experiement for that day. We are extracting Limonene oil from Orange rinds( orange zest for thoughs cooks out there). First, we fill a tube with a copper mesh on the bottom half with the rind and the rest with compacted, crushed dry ice. The sealed tube is placed in the hot water so that the ice can begin to sublime. As the pressure builds, the ice can no longer sublime anymore. Instead, the pressure causes the ice to melt in to liquid carbon dioxide, and boil on contact with the rinds. Almost like liquid nitrogen, but warmer. As the liquid goes through the rinds, it picks up the oil, and anyother oils in the rinds, and brings them down to the bottom of the tube. This is a similar technique some companies use to decaff coffee with out using harmful solvents. Just as a note, there is no mixer in the graduated cylinder, the tube is spinning on its own This video was shot with my blackberry, so i know that the video quality is crappy and the audio isnt very good.

          Friday January 20th, 2017 10:17 Stone Veneer

          Stone veneer is a modern way to decorate the walls of a developing. The stone veneer cladding offers a stylish method adopted by architects to impart a dynamic look to a lifeless construction. This is mostly used for aesthetic purposes and has a long life. The elegance and simplicity of stone veneer provides homeowners, architects, builders and developers with a versatility and versatility to be more to resourceful. Stone veneer is also effectively used in landscape and complementing the natural beauty of the open spaces as well.

          Stone Veneer acts as a decorative and protective covering on exterior as well inside walls and surfaces. The veneer is generally one inch heavy; it is lighter in weight in weight and weighs about 15 lbs. / sq. ft. It does not need any extra structural support for its installation.

          Stone Veneer is mostly made from natural stones. It can also be produced from manufactured stones. The natural stone veneer is manufactured from stone, which is collected from quarries or as field stone. The stone is then sawn making use of huge diamond impregnated cutters equally spaced to get the slices of the stone in a consistent thickness and weight. This stone is also known as “thin stone veneer”.

          Besides the natural stone veneer, manufacture stone veneer is also a ornamental building material. It is produced to imitate the appearance of natural stone. There are a number of names used for this type of veneer. The stacked stone veneer, artificial stone veneer, manufactured stone veneer and flexible stone veneer are various names used for stone veneer.

          Stone veneer is produced by mixing a lightweight concrete mix to rubber molds of different type. These are painted with a coloring process to make them resemble the real stone. yet another method to make stone veneer is by casting and molding it from chemically modified lightweight concrete. Stone veneer is actually a replica of natural stone. It takes the finest details of the original stone. At a close look, the artificial stone veneers appear just like original stones.

          The stone veneer is mostly used as a siding on the walls. It can be fixed on the walls using unique top quality mortars for highest adhesion and strength. versatile stone veneer is manufactured by slicing a thin layer of a stone. It is then backed by some composite material. It can be produced in a variety of designs and colors making use of different stones. The manufactured stone veneer is less costly than natural stone veneer and there is the least amount of wastage in its use.

          Manufactured stone veneer costs almost 1/3 to 1/2 the cost of making use of natural stone. due to the fact of the lightweight of the manufactured stone veneer, there is no need for wall ties or any footings. It tends to make the construction easier and Thereby lessens the cost. There is a vast variety of designs, patterns and colors available on manufactured options as compared to the natural stone mainly because the natural stone is generally used in the area around where it is extracted due to the huge transportation costs.

          Manufactured stone veneer is relatively less strong as compared to natural stone rock walls, but many applications do not call for higher strength as visuals is a more important factor in many cases. Stone veneer is also not reusable like natural stones.

          Stone veneer provides the natural look of the stones at inexpensive price ranges. Stone veneers are preferred these days for most of decorative facing in makings and open spaces.
