Four major Contributions of Chemistry in modern science & technology

  Four Major contributions of Chemistry in modern science & technology

There are a lot of advancements in the last few decades. Since many years, the world hasn’t stopped excelling in almost all the aspects, be it digitally or biologically. The inheritance of a lot of great achievements keep making buzz in every corner.

Okay! So when there is advancement in any physical or biological substance, it tends to be more popular in comparison to chemistry. Chemistry is more likely to get overlooked. Even in today’s time, not even a single chemist has made it to Science magazine’s Top 50 Science stars on Twitter.

Thus, here we bring for you the top five chemistry inventions that have actually brought a big fat change or advancement in the world that we currently live in.

 1.The Haber-Bosch process

At this time, 80% of the Nitrogen in our bodies comes from the Haber-Bosch process, which also is a major reason for the population explosion in the past 100 years.

 Nitrogen is the most common gas available in our atmosphere, thus plays a critical role in the biochemistry of every living thing. Majorly Nitrogen gas doesn’t like reacting much, ehich eventually makes it troublesome for plants and animals to extract it form the air. Consequently, major limiting factor in agriculture has been the availability of nitrogen.

 German chemists Fritz Haber and Carl Bosch together brought the change in this scenario as they combined atmospheric nitrogen and hydrogen into ammonia. This in turn can be used as crop fertilizer, eventually filtering up the food chain to us.


Penicillin holds a great history taking surpassingly the title of the life saver. To no surprise, Penicillin works as wonder for sore throats as well as many fatal diseases.

The credits for a wonder drug like Penicillin is often given to Alexander Fleming but it is known by very few that Alexander Fleming did started the observation of how a mould growing on his petri dishes suppressed the growth of nearby bacteria. Though, he didn’t really got success in finding any usable penicillin despite of his innumerable efforts.

It was after 10- year hiatus that an Australian pharmacologist Howard Florey and his team came and figured out the way of purifying penicillin in useable quantities.

Too shy to come up-front, all the limelight shifted to alexander. 

Full-scale production of penicillin took off in 1944 when the chemical engineer Margaret Hutchinson Rousseau took Florey’s Heath Robinson-esque design and converted it into a full-scale production plant.

 3.Polythene – the accidental invention

From food packaging to water pipes, they all are a form of polythene. Surprisingly, the invention of this 80 m tonne of the stuff that is made each year is accidental.

A German chemist Hans von pechmann noticed a waxy substance at the bottom of his tubes for the very first time in 1898. After that he went through a tight investigation regarding it along with his colleagues but no big discovery could be done.Later on in 1933, an entirely different method was discovered by chemists for making the plastic. Practical method for producing the common plastic that’s almost certainly within easy reach of you now.

 4.The screen you are reading on

This concept of flat- screen color displays peeped out in the late 1960s when the British Ministry of defence decided it wanted flat- screens to replace bulky & expensive cathode ray tubes for its military vehicles. The discovery was based over the idea of the liquid crystals.

 It was known beforehand that liquid crystal displays (LCDs) were possible, but the problem was that it worked properly just at high temperatures.

It was George Gray who invented a molecule known as 5CB and made this possible. George Gray was commissioned by the MoD in 1970 at the University of Hull to work on a way via which the LCD’s work in the regular environment too and he did exactly that.

By the late 1970s and early 1980s, 90% of the LCD devices in the world contained 5CB. The 5CB molecule can even be found in cheap watches and calculator.

Meanwhile derivates of 5CB mark the invention and proper work of phones, computers and TVs possible.

Purpose of GOAL institute-

After going through such hidden marks made by the chemists via chemistry is impeccable. These were just those inventions which are regular to us, there is much more that chemistry has given us all. Thus, GOAL institute intends to incline deep into the need to study chemistry and help students strengthen their chemistry for NEET exams. NEET is a very critical subject to deal with and definitely not an easy job. GOAL knows that it is chemistry which usually gets trouble to peopleand hence, top faculty of the place is being hired at GOAL institute. To get the candidates prepared for the NEET exam.  GOAL institute keeps updating them with 3-months Preparation Tips for NEET or Quick tips for the preparation of NEET.

NEET exams are the most important part of one’s career if they wish to opt medical. In GOAL institute, we create opportunities
