Transparent materials

Small cracks, cavities, and notches in perfect material can dramatically reduce the tensile strength by producing stress concentration around them [ref]. We believe that in mammalian connective bone tissues, canaliculi, osteocyte lacunae, blood vessels and muscle insertions produce stress concentration to delay the progressive spread of minute cracks. Often times the cracks that are running against lacunae, for examples, stop on entering the lacunae, Hessian canals and blood vessels [ref]. We…

If we really want to save the environment then we should get rid of plastic water bottles! Why get rid of plastic water bottles? Well, because first of all, it is horrible for the environment, and because it is a big scam. We might as well buy electricity in a can for a lot more money. Because that is what plastic water bottles are doing. Trashing the environment First of all it is horrible for the environment. According to “The Story of Bottled Water” it says, in one year just in the U.S we…

When engaging in a dialogue about bottled water, it is vital to recognize both sides of the argument to generate progress and make concessions that identify its positive and negative effects. However, it is unquestionable that the negative effects of bottled water exceed its positive effects, because its negative effects on human health and the environment supersedes all the positive effects it has such as its convenience for consumers. With our planet being exploited of its resources and being…

really a chance to be reminded of or learn about the benefits associated with the many wood species out there. Here's what you should consider when planning to use plywood for custom bar tops in Houston. Versatility: When selecting a building material, a lot of people opt for something that is versatile, especially if they are building more than one thing. For example, they plan to use the wood for cabinets,…

Whenever the word nitro comes up it turns to something explosive. In chapter 5 it is mainly about nitro compounds and it explains what is and how it works based on the molecular structure. Nitro compounds are indeed explosive. Gun powder can be considered one of the earliest items to be referred as a fire chemical component. The gun powder components are known to be all reactive products which cause the reaction of an explosion. Nitro compounds are highly reactant and is stabled by a molecule…

Properties; Beryllium is a toxic bivalent element; with a steel gray metallic look to it. Beryllium is also a durable, lightweight element. Primarily used as a hardening agent in alloys. It has one of the highest melting points of the light metals. With the atomic number of 4, and being classified within the group of alkaline earth metals. The element is nonmagnetic and resists oxidation when exposed to air at standard temperature and pressures. It’s also found in over 30 different minerals; for…

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…

When it comes to selecting the right fastening devices for successful completion of a project, there are many factors to consider. However, once you have determined that screws are the best choice for the job, you will need to decide which type of screws will best serve your needs.

With plastic having so much prevalence today, it’s hard to believe that it can also have adverse side effects on the body as well. Phthalates are used in the production of plastic to allow it…

implement all of their ideas into one tent; this approach is very different than ours where we only had two animals. They somehow were able to put all of their ideas into one application. I also thought it was very smart to focus on phase change materials for DP3. I also fill like because of their numerus animals they were able to pick the perfect properties for what they want, while we did some research but not as extensive, so it is possible that we missed the best animal to our application. I…
