#October 23 #Mole Day #Avagadro's Number

  
       Mole day is unofficial holy day Celebrated by chemists annually from 6.02 am to 6.02 pm on October 23rd, Mole Day commemorates Avogadro’s number (6.022 x 1023), which is the number of atoms in exactly 12 grams of carbon-12 (one mole). 
This was founded by the National Mole Day Foundation on 15th May 1991.You may be thinking that this day is in honor of the little burrowing creature. However, it is not.  
This celebration takes place between 6:02 AM and 6:02 PM, making the date 6:02 10/23 in the American style of writing dates. 
The time and date are derived from Avogadro’s number, which is approximately 6.02×10^23, defining the number of particles (atoms or molecules) in one mole of substance, one of the seven base SI units.
  This number is dimensionless and named after Italian scientist Amedeo Avogadro.The National Mole Day Foundation founded in 1991 celebrates the day every year with a theme. Some of the recent themes include Molar Eclipse in 2012, Mole of the Caribbean in 2010, and Molar Express in 2009.
  • A mole is a unit of measurement used in chemistry to express amounts of a chemical substance.
  • Avogadro’s number is a historical term closely related to the Avogadro constant.
  • The Avogadro constant is named after the early 19th-century Italian scientist Amedeo Avogadro.
 History
       National Mole Day originated in the early 1980s in an article from The Science Teacher.  Prairie du Chien, Wisconsin  High School chemistry teacher, was inspired by the article and founded the National Mole Day Foundation on May 15, 1991

How to Celebrate?

  *Get your geek on for this day. Wear a mole t-shirt and when someone asks you about it,explain the concept of mole to them.
  *Have a mole-themed party and serve guaca"mole" and wear mole (the animal)  costumes.

Chemistry in Coronavirus Research

Coronaviruses represent a large family of viruses that elicit respiratory illness in humans, including the common cold and more serious diseases, such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). This group of viruses can also infect animals and are zoonotic, meaning they can be transmitted between animals and humans, as was  shown to be the case for MERS and SARS . In fact, some species of animals, such as bats, act as reservoirs for carrying wide varieties of viruses, and severe viral outbreaks in the human population such as for SARS and MERS tend to occur when these viruses jump from animals to humans when given the opportunity due to close interaction. The novel coronavirus (currently referred to as 2019-nCoV) was first detected in Wuhan, China, in December 2019 and appeared to initially affect people who had visited a seafood and animal market selling live game, but person-to-person spreading occurred as well. Investigations on th...

Croyo-Electron Microscopy

  This  technic is the main reason for wining Nobel price of chemistry  2017.C ryo-electron microscopy  ( cryo-EM ), or  electron cryomicroscopy , is a form of  transmission electron microscopy (TEM) where the sample is studied at  cryogenic  temperatures (generally  liquid-nitrogen  temperatures).Cryo-EM is gaining popularity in  structural biology . The utility of cryoelectron microscopy stems from the fact that it allows the observation of specimens that have not been stained or fixed in any way, showing them in their native environment. This is in contrast to  X-ray crystallography , which requires crystallizing the specimen, which can be difficult, and placing them in non-physiological environments, which can occasionally lead to functionally irrelevant conformational changes. The resolution of cryo-EM maps is improving steadily, and in 2014 some structures at near-atomic resolution had been obtained, including tho...

ORIGIN OF GOLD ,SILVER and PLATINUM

N An illustration of two neutron stars colliding For the first time, astronomers have detected a neutron-star collision. Gravitational waves heard by two detectors pinpointed the source to a galaxy 130 million light-years away. The collision produced a radioactive "kilonova" that forged hundreds of Earths' worth of platinum, gold, silver, and other atoms. The discovery solves a longstanding mystery about the origins of heavy elements. Platinum and gold are among the most precious substances on Earth, each fetching roughly $1,000 an ounce. However, their allure may grow stronger - and weirder - thanks to a groundbreaking new finding about their violent, radioactive, and cosmic origins. On Monday, scientists  who won a Nobel Prize  for their discovery of gravitational waves, or  ripples in the fabric of space , announced the first detection of the collision of two neutron stars. The team alerted astronomers all over the world to the event right afte...
