Enhancement of Fracture Toughness through Atomic Scale Crack Bridging in Graphene with Stone-Thrower-Wales Defects G. Rajasekaran and Avinash Parashar Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India ABSTRACT Keywords: graphene, defect engineering, Stone-Thrower-Wales defect, crack bridging, stress intensity factor, fracture toughness. 1. Introduction Graphene is a hexagonal two-dimensional (2D) monolayer of honeycomb lattice packed carbon structure that was discovered and successfully isolated from bulk graphite just a few years ago [1]. It is a promising candidate in a number of mechanical, thermal and electrical applications [2-6], owing to its outstanding physical properties [2]. In addition to enormous nano-technological applications, graphene also attracts prodigious attention as strengthening element in composites [7-10]. Characterization of the mechanical properties of graphene is essential both from a technological perspective for its reliable applications and from a fundamental interest to understanding its deformation physics [11-13]. In material science, fracture toughness is a property that describes the ability of a material containing a crack to resist fracture, and is one of the most important mechanical properties of any material [14-15]. The useful strength of large area graphene with engineering relevance is usu ally determined by its fracture toughness, rather than the intrinsic strength

Animal Testing As A Tool For Growth Among Many Industries

Since you were born animal testing was used in your everyday products. The Pampers, Band-Aids, and Visine you purchased were all animal tested products. Every year, millions of animals go through painful experiments usually resulting in death. Normally, scientists use animals to determine and refine a variety of drugs, vaccines, cosmetics, and other chemicals. In the past 50 years, the United States used animal testing as a tool for growth among many industries. With 80 million animals painfully killed in U.S laboratories, animal experimentations has been a heavy controversial topic. Although people truly benefit from animal research, the inescapable pain, suffering, and death are not worth the benefits. Animals used in the name of research is wrong and needs to be stopped. There is the slightest bit of enforced regulation when it comes to animal testing. The Animal Welfare Act (AWA) is the one and only federal law that ensures humane protection, treatment, and transportation for ani mals in laboratories (Neavs 2014). Unfortunately, the AWA only protects certain species while denying rats, mice, and birds that make up about ninety percent of animals in facilities. The remaining ten percent are warm-blooded animals such as: dogs, cats, monkeys, rabbits, which are covered by minimal regulations for housing, feeding, and psychological well-being. The pain and suffering animals encounter are not worth reaping the benefits. Pain in animals is an aversive sensoryShow MoreRelatedCase Study for Avon8396 Words   |  34 PagesExternal Environment [PEST] 1. Political/Legal 2. Economic 3. Social-cultural 4. Technological B.

The Glass Castle By Jeannette Walls - 1356 Words

One bottle after another was the everyday life of Rex Walls. In many occasions, Rex frequently moved his family around and changed the place they called home. In reality, the only thing that needed changing was Rex’s bad habits of alcohol. He was a true example of someone suffering from alcoholism which effected himself and everyone around him. Alcoholism is a medical condition in which an individual frequently consumes too much alcohol and becomes unable to live a normal life (Campbell). In the memoir The Glass Castle, written by Jeannette Walls, Jeannette exposes the cruel reality she and her family had to face growing up. She recalls all the empty nights when she would have to go from bar to bar looking for Rex, and unmask the difficult times that came with having a father overpowered by alcohol. Her father’s abuse of alcohol affected his children’s life growing up and destroyed any chance of his family ever living a normal life. In many occasions individuals that suffer from alcoholism are selfish. It is considered selfish because they make drinking alcohol a priority in order to medicate their feelings. They make it a priory above everything and even their own families (Morris). The feelings that an individual suffering from alcoholism experiences inside are often why they consume large amounts of alcohol daily. Alcoholics use alcohol to fight their feeling and run away from what is haunting them inside, when in reality they are only running away from themselves.

Of Dispatch Essay Example For Students

Of Dispatch Essay Affected dispatch is one of the most dangerous things to business that can be. It is like that, which the physicians call predigestion, or hasty digestion; which is sure to fill the body full of crudities, and secret seeds of diseases. Therefore measure not dispatch, by the times of sitting, but by the advancement of the business. And as in races it is not the large stride or high lift that makes the speed; so in business, the keeping close to the matter, and not taking of it too much at once, procureth dispatch. It is the care of some, only to come off speedily for the time; or to contrive some false periods of business, because they may seem men of dispatch. But it is one thing, to abbreviate by contracting, another by cutting off. And business so handled, at several sittings or meetings, goeth commonly backward and forward in an unsteady manner. I knew a wise man that had it for a byword, when he saw men hasten to a conclusion, Stay a little, that we may make an end the sooner. On the other side, true dispatch is a rich thing. For time is the measure of business, as money is of wares; and business is bought at a dear hand, where there is small dispatch. The Spartans and Spaniards have been noted to be of small dispatch; Mi venga la muerte de Spagna; Let my death come from Spain; for then it will be sure to be long in coming. Give good hearing to those, that give the first information in business; and rather direct them in the beginning, than interrupt them in the continuance of their speeches; for he that is put out of his own order, will go forward and backward, and be more tedious, while he waits upon his memory, than he could have been, if he had gone on in his own course. But sometimes it is seen, that the moderator is more troublesome, than the actor. Iterations are commonly loss of time. But there is no such gain of time, as to iterate often the state of the question; for it chaseth away many a frivolous speech, as it is coming forth. Long and curious speeches, are as fit for dispatch, as a robe or mantle, with a long train, is for race. Prefaces and passages, and excusations, and other speeches of reference to the person, are great wastes of time; and though they seem to proceed of modesty, they are bravery. Yet beware of being too material, when there is any impediment or obstruction in mens wills; for pre-occupation of mind ever requireth preface of speech; like a fomentation to make the unguent enter. Above all things, order, and distribution, and singling out of parts, is the life of dispatch; so as the distribution be not too subtle: for he that doth not divide, will never enter well into business; and he that divideth too much, will never come out of it clearly. To choose time, is to save time; and an unseasonable motion, is but beating the air. There be three parts of business; the preparation, the debate or examination, and the perfection. Whereof, if you look for dispatch, let the middle only be the work of many, and the first and last the work of few. The proceeding upon somewhat conceived in writing, doth for the most part facilitate dispatch: for though it should be wholly rejected, yet that negative is more pregnant of direction, than an indefinite; as ashes are more generative than dust.
