Introduction A Voltaic Cell (also known as a Galvanic Cell) is an electrochemical cell that uses spontaneous redox reactions to generate electricity. It consists of two separate half-cells. A half-cell is composed of an electrode (a strip of metal‚ M) within a solution containing Mn+ ions in which M is any arbitrary metal. The two half cells are linked together by a wire running from one electrode to the other. A salt bridge also connects to the half cells. Through electrochemistry‚ these reactions

Innovation: Championing 3M’s Post-it Notes by Knowledge@SMU‚ 13 April 2010 Go ahead and experiment with your idea. But what if I fail‚ you may ask. It is okay‚ said Geoff Nicholson‚ a former senior executive with multi-product manufacturer 3M‚ famous for its wide range of innovative products for both consumers and businesses. In fact‚ that is the trait you should look for in your employees – people who are not afraid to make mistakes – if you want your company to go far in innovation‚ said

Remember ‘Remembrance Day?’ I sat cross-legged on the blotchy carpet‚ splattered with an abstract painting. My elbow rested on the dent in my knee. My fingers touched the fluffy texture beneath me‚ tracing the scattered shapes. Beside me‚ Jenny sat with her legs unfolded‚ her body was leant back‚ making her amber hair droop across her shoulders‚ with her arms propping herself up. Her skin contrasted with the dark orange carpet; her eyes fluttered around the room‚ where a group of girls sat in

as it spins. An adjustable horizontal metal rail or the tool rest is placed between the material and the operator accommodates the positioning of shaping tools‚ which are usually hand-held. With wood‚ it is common practice to press and slide sandpaper against the still-spinning object after shaping to smooth the surface made with the metal shaping tools. There are also woodworking lathes for making bowls and plates‚ which have no horizontal metal rail‚ as the bowl or plate needs only to be held

Key Words Abrasion: Bits of rock and sand in the river grind down river banks and river beds like sandpaper. Alluvium: load particles (clay‚ silt‚ sand and gravel) deposited by a river. Attrition: Water smash rocks and pebbles on the shore into each other‚ and they break and become smoother. Discharge: The amount of water in a river at any given point

Sensorial Education Introduction to Sensorial What is Sensorial Education? Sensorial education can simply be defined as the training of senses of children for future learning. What is Sensorial Work Sensorial comes from the words sense or senses. It helps the child to be able to concentrate on the refinement of all his senses‚ from visual to stereognostic. The Purpose of Sensorial Work The purpose and aim of Sensorial work is for the child to acquire clear‚ conscious‚ information and

“The senses are points of contact with the environment.” How does activity with the sensorial materials encourage observation and perception of the environment? The child in his mother’s womb is a physical embryo; He develops his physical structures and increases in size while in the womb. Once he is born‚ leaving the comfort of his mother’s womb‚ he must go through a phase of reconstruction or incarnation. He must become like his parents in movement‚ speech and other areas. To do this he does

Determination of an Electrochemical Series In electrochemistry‚ a voltaic cell is a specially prepared system in which an oxidation-reduction reaction occurs spontaneously. This spontaneous reaction produces an easily measured electrical potential which has a positive value. Voltaic cells have a variety of uses and you commonly refer to them as a “battery”. Half-cells are normally produced by placing a piece of metal into a solution containing a cation of the metal (e.g.‚ Cu metal in a solution
