Polymer
Hello,
The average package offered in the Polymer Science and Technology branch at Calcutta University can vary from year to year based on several factors, including market conditions, the performance of students, and the reputation of the university among recruiters.
As of the latest data available:
Hope it helps you!
Question : Read the passage and answer the following questions. IIT Delhi researchers have designed and fabricated a device that can generate electricity from water drops, raindrops, water streams, and even from ocean waves using "Triboelectric Effect" and "Electrostatic Induction". The device is called "Liquid-solid Interface Triboelectric Nanogenerator". The generated electricity can be stored in batteries for further use. Triboelectric effect is a known phenomenon for a long time, and in this effect, charges are generated when two surfaces are in friction. The best example we see are sparkling lights when we move the blankets/jackets.
The device has a very simple structure consisting of specially designed nanocomposite polymers and contact electrodes and can generate a few Milliwatt mW power, which is sufficient to power small electronic devices like watches, digital thermometers, radio frequency transmitters, healthcare sensors, pedometers. When compared to conventional methods, such as the use of the piezoelectric effect, the present device can generate significantly more electricity.
The researchers successfully incorporated nanostructures into a polymer matrix, which enhanced the film's surface roughness, polarizability, and hydrophobicity, among other characteristics, as a result. Due to the enhancement in the above property, the flexible film is used to fabricate the device where raindrops have just to slide down and can generate electricity. The artificially created rough surface allows to generate more charge and superhydrophobic properties of the solid surface help to roll the water drop without getting stick to the surface.
The IIT Delhi research team also explored the underlying mechanism of the electricity generated when the water drop comes in contact with the solid surface and it is shown that saline water drops generate more electricity. The researchers also showed that the device can even work with ocean waves, where the water is saline, and through the ocean waves contacting the surface of nanocomposite polymer film, electricity is generated.
Question:Name the electronic devices which can be powered with the device mentioned in the passage: 1. Watches 2. Pedometers 3. Refrigerators 4. Radio Frequency Transmitters
Option 1: Only 1 and 2
Option 2: All 1,2,3, and 4
Option 3: Only 3 and 4
Option 4: Only 1,2 , and 4
Correct Answer: Only 1,2 , and 4
Solution : The correcrt option is 4 i.e "Only 1, 2, and 4." Explanation:
Let's refer to the following lines of the passage:
The device has a very simple structure consisting of specially designed nanocomposite polymers and contact electrodes and can generate a few Milliwatt (Mw) power, which is sufficient to power small electronic devices like watches, digital thermometers, radio frequency transmitters, healthcare sensors, pedometers. The above statement clearly mention the watches, pedometers and radio frequency transmitters.
The program chiefly incorporates investigation of polymers blend, polymer properties, polymer handling, polymer testing, polymer corruption, polymer response, composites, and applications. The Polymer Science course is professionally situated and can give different open doors in the field of polymers.
It incorporates Subjects like:
Inorganic Chemistry and Organic Chemistry
Theoretical Chemistry
Inorganic Chemistry and Organic Chemistry Practical
Physical Chemistry Practical
Hello Student
You have not mentioned the particular name of the examination in which you want to appear and in which study you are going to take and are continuing so far. If it is class 12 exam and biology is your subject in the two different theme of study that related to biology is not possible to complete in one day.The total preparation of the subjects will take at least 3 to 6 months rigarus study, that include practice and revise of previous years question paper and taking mock tests of the related subjects.
Hope this will help.
Hii there!
Here are the names of the chapters in hindi language-
Hope this helps!
There is no official information regarding the average packages offered in bit mesra for any branch but yes the number of student placed in 2021 from chemical plastic and polymer were 28% and in production the stat is about 44% if you are not inclined towards any particular subject then my recommendation would be to go with production and industrial engineering as it is very much similar to mechanical engineering and in future demands of such engineers is going to increase where as chemical engineering in india does not have many opportunities but yes production will be a good decision so choose wisely
Hello Aspirant, Hope you are doing well.
Because it encompasses all parts of electrical engineering and has extensive experience in the manufacture and maintenance of instruments, instrumentation seems to have a wider application span. Construction, heavy metals and mining are among the many industries with good potential for growth. Polymer engineering, on the other hand, focuses on chemical compounds and their aesthetics, as well as all of their associated byproducts. Polymer engineering The scope of the project is restricted to chemical processing and pharmaceutical firms. Hope you got the answer to your question. Incase of any queries, feel free to question. Have a great day!
JEE Main Syllabus (Polymers) :
Dear Aspirant,
given below are some of the post graduation courses you can pursue in Polymer courses,
hi,
see there is various courses available but you must select any course as per your future goal. you may join diploma in chemical engineering or m.sc course related with polymer chemistry. another excellent option is m.sc in biotechnology which is a diverse filed and wise research options. you have to decide whether you want to go for higher study or job related courses. another option is mba, which has excellent industry exposure and excellent career options. you may choose mba course in pharmaceutical management, hospital management .
hope it would help.
