Graphene, known as the "universal material", can't be done in the end? With the increasing popularity of graphene applications, scientists and researchers have found that graphene can be used in a wide range of fields. From mobile power to repairing the spinal cord, graphene can always make people's eyes shine. Now, scientists have discovered that graphene has another new application that can be used to discover cancer cells.
Graphene, which has only one carbon atom thickness, is the world's thinnest, hardest, and least resistive nanomaterial. The new application of graphene was proposed by scientists at the University of Illinois at Chicago. They placed mouse brain cells on graphene sheets to form a thin layer of atomic carbon atoms. It was found that graphene sheets can distinguish what is normal. Cells, what are cancer cells.
Vikas Berry, an assistant professor at the University of Illinois at Chicago, who participated in the study, pointed out that this graphene system can detect the different activities of cancer cells, which would cause graphene when normal cells or cancer cells were bonded to the surface of graphene sheets. The charge distribution is rearranged to change the atomic vibrational energy that scientists detect when using Raman spectroscopy.
Graphene is a planar single-layer film structure composed of a carbon atom closely packed into a two-dimensional honeycomb lattice. When graphene is bonded to normal cells or cancer cells, the atomic vibrational energy in the lattice structure will be different. Because the cancer cells are extremely active, the surface will release more protons and a higher negative charge, and the scientist is By this characteristic, to distinguish what is a cancer cell.
Although it is still in the animal experiment stage, scientists will use the biopsy method to test it. This method of distinguishing graphene is also expected to be used to distinguish other types of cells and even to identify sickle cells.
Electric dc motors were the first type widely used, since they could be powered from existing direct-current lighting power distribution systems. A electric Dc Motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small electric dc motor are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight motor used for portable power tools and appliances. Larger electric dc motor are used in propulsion of electric vehicles, elevator and hoists, or in drives for steel rolling mills.
Areas of application: the electric dc motor rotor part of the armature iron core, armature, commutator, such as equipment, electric dc motor is suitable for most electronic products, such as electric screwdriver, laser, smart home, gas valve, etc
Applications:
Method of use: the best stable in horizontal plane, installed on theelectric dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the electric dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Electric dc motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a electric dc motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Electric dc motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of geared motors is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
