canoeing safaris or other types of water sports. It is well to note that the Skorch waterproof backpack should not be totally submerged in water but should it fall in water it will float and keep your belongings dry. It is made from durable UPVC material and built to last. If it does get dirty it is very easy to clean by wiping the dirt off with a wet cloth. It has good reviews and some people have even submerged the bag and all the baggage came out dry. It has excellent customer comments and…

3.1.3 FESEM and EDS analysis The structural morphology of the Pure HA, Sr-doped HA, La-doped HA and La/Sr co-doped HA (different La concentrations of 0.03, 0.06 and 0.1M) nanoparticles are analyzed by FESEM images are shown in Fig. 3 (a)-(f). The morphology of pure HA shown in Fig 3 (a) indicates that formation of spherical (or) chain pearl shape of nanoparticles, ranging from 70 to 84nm. Further, Sr (0.1M) doped HA and La (0.1M) doped HA belongs to Fig.3 (b)-(c), appears the formations of few…

Paragraph 1 Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. Haines’ research paper studies the change that occurs in the FePO4 structure as it is studied from temperatures 294K to 1073K. A transition is noticed at 980K, when it’s tetrahedral α-quartz structure experiences high pressure levels, changing the structure to β-phase, a more dense octahedral structure. Cell parameters of FePO4 in α-phase increases in cell parameters and volume as…

What to do with all these water bottles! Humans are slowly killing the planet! Pollution of the planet is not a new concept, humans having been trying to figure out how to combat this problem. Unfortunately it is not fully working, so instead individuals have come up with ways to repurpose pollution. One such item would be water bottles. In this synthesis of sources different people have took a crack at helping the environment in their own way. In two articles, “Eco-village in Panama” written…

magnesium as the major alloying elements constitute a group of non heat treatable alloys (AA5XXX series) used for structural materials in automotive, aircraft and marine applications. Welding of this alloy using conventional technique leads to vaporization of Magnesium, which causes compositional changes in the weld seam [9]. Hence, to regain the Mg content (from AA5XXX series materials) FSW may be the feasible technique to overcome this…

water absorption and smooth texture of finely ground quartz particles. Fig. 9, 10 described water reduction effect of adding crushed quartz filler to maintain a fixed flow of MgO-SF-QF ternary systems (Series 3, 4, 5). The replacement of cementitous materials by crushed quartz filler improves rheology considerably, expressed by the consistent reduction of water content while maintaining a minimum flow of 120-125 mm for workability. The amount of reduced water is proportional to the increase…

Did you know that some states have passed laws making it illegal to throw batteries away in the garbage? Many people are unaware of this fact. In 1991, the state of North Carolina rendered it illegal to discard of lead-acid batteries in a landfill, incinerator or any other type of waste-to-energy facility. The purpose of this report is to provide you with information on rechargeable batteries so you will have a better understanding on the benefits of a recycling program and possible…

deposition, it is possible to produce alloy and compounds of metals and nonmetal materials. Chemical vapor deposition can be defined as the deposition of a solid on a heated surface from a chemical reaction in the vapor phase [2]. Chemical vapor deposition belongs to the class of vapor-transfer processes. Differ from physical vapor deposition, CVD process includes chemical reactions. In the process, gaseous material change in to solid which means the process is…

There are many different materials that can be used for eyeglasses. They all have advantages and disadvantages. When it comes to how your brain creates images and why they differ there are many different body parts that have a big effect. With that being said two materials that are used for eyeglasses are plutonite and the hydrophobic lense coating. These two materials are two of the most used for eyeglasses as they have many advantages that are not provided by other materials. There are also…

temperatures. Stretch forming is a method that combines controlled tension and bending of sheet material around dies to produce accurately contoured parts. It is extensively used in the aerospace industry to form large sheet panels of mild curvature, e.g. the leading edge of a wing. A commonly used material for aircraft skins is the heat-treatable aluminum alloy AA 2024. Possible failure modes during forming of this material are necking, wrinkling, $L\ddot{u}$ders lines or orange peel. In order…
