Electrode

the anode to the electrolyte in an oxidization reaction. Those electrons are then accepted by the cathode, creating a circuit where electrons flow from anode to cathode. The electrolyte facilitates contact between the chemicals in both electrodes. This contact ends up converting chemical energy into electrical energy. i. It is also known how a battery 's construction works to transform chemical energy stored in the battery into electrical energy that can be utilized. 4. It…

Cochlear implants, also known as the “bionic ear”, are devices that help provide aid for those hard-of-hearing. These devices are extremely complex and contain parts that are forced to work as a functioning unit. I will be going into more in depth with cochlear implants as well as defining what a cochlear implant actually is. I will also explain the costs that are involved, who the “best candidate” would be for implantation, and the risks and benefits involved with the implant. According to the…

Inhibition serves as an important psychological function which enables the mind to filter out stimuli that are irrelevant to the task/process that is being performed or to the current state of the mind (MacLeod, Colin, 2007). In psychology, it refers to the ability to constraint or curtails certain behaviours, especially impulses and desires consciously or unconsciously. In the real life, it prevents us from acting impulsively such as physically retaliating against someone who insulted us and to…

Abstract The paper present the investigation on the effect of temperature, time and current density on surface roughness in electropolishing process on 316L stainless steel. The cathode material under study was 316L stainless steel. The electrolyte was composed of sulfuric acid, phosphoric acid, and DI water. Full factorial design method was used. ANNOVA technique has been used to assess the quantitative influence of the different process factors of the EP. The surface roughness will be…

Reflexes and reactions are two different ways that the human body responds to external or internal stimuli. Reflexes are involuntary and send a message only through the spinal cord to act on a stimuli without any intervention from the brain. For example, sneezing is a reflex as it is an attempt to rid the body of possibly harmful particles (external stimulus) from entering the body. Another example would be immediately pulling the hand away after touching a hot (external stimulus) pot. All of…

information to the brain, specifically the visual cortex in the case of someone who is blind. There are two types of ways to gather signals out of the brain and have those signals connect to the computer. There are invasive BCIs, which is where electrodes are implanted into the brain; partially-invasive BCIs which is put inside the skull but not the brain; and…

Electroconvulsive Therapy Electroconvulsive therapy is a medieval use of electricity to attempt to “rewire” the brain to treat psychological disorders. This type of therapy causes a vast array of possible complications that can follow the procedure; cognitive issues such as memory loss and physical ones such as musculoskeletal injuries. Electroconvulsive therapy should be abolished because it poses too great of a danger to patients. This Therapy has been a leading issue in the regard of…

others only have one a month or less. To be able to track the progress of the disease and to alarm caregivers during a convulsion, these patients should be monitored. The gold standard in convulsions monitoring uses EEG-electrodes [28] attached to the scalp. However, these electrodes are difficult to…

The carbohydrates present on the cells surface can act as a receptor for many pathogens to facilitate cell-cell adhesion through which humans can be infected, for example, mannose binds pathogenic bacteria E. coli and sialic acid binds influenza virus. Therefore, cell surface can be mimicked by preparing SAMs of carbohydrates to study and understand different types of binding and inhibition studies in vitro. SAMs of carbohydrates are also used for detecting disease biomarkers and carrying drugs.…

A typical underwater welder would have a diving helmet, diving suit, electrodes, stinger, an underwater welding machine (Welders, 2015). The diving helmet protect the diver’s eyes and face during the job. There are different type of helmets such as an open circuit, reclaim, and a free-flow. An open circuit helmet uses a non-return…
