Dow isolated bromine

 Jan 04 : Dow isolated bromine

This new method of electrolysis greatly simplified the process for isolating bromine (Br2). Dow became the founder of Dow Chemical Company and was a pivotal figure in developing America’s chemical industry.

Rutherford penetrated the nucleus

 Jan 03 : Rutherford penetrated the nucleus

Upon bombarding nitrogen atoms with alpha particles, he observed the release of a proton. Patrick Blackett later discovered that this was a transmutation of nitrogen to oxygen.

Rudolf Clausius

 Jan 02 : Rudolf Clausius was born

He was one of the central founders of thermodynamics. He introduced the concept of entropy and stated the second law of thermodynamics for the first time. He also introduced concepts of kinetic theory to explain motion of gas molecules, in particular the mean free path of particles.

Jan 01 Eugène Demarcay

 Jan 01: Eugène Demarcay was born

In 1901 he used spectroscopy to analyse material that had been carefully separated from samarium magnesium nitrate and discovered the element europium (Eu). His specialist knowledge of spectroscopy also helped Marie Curie confirm she had discovered radium (Ra).

The drunkometer

 December 31 : 

The drunkometer was invented on this day in 1938


It was the first successful machine for testing blood alcohol content through breath testing. The machine used acidified potassium permanganate solution as a colour indicator for the amount of alcohol present.

Ductile tungsten for incandescent bulb filaments was patented on this day in 1913

Chemoinformatics databases

Cheminformatics can be broadly defined as the field of solving chemical problems with computers. 
In contrast to classic computational chemistry, the emphasis is on practical questions. 
How can one represent molecules computationally, how can one compare them and predict their effects in biological systems?

Chemoinformatic methods are widely used in chemical industry, particulary in pharmaceutical and biotechnology research. 
The techniques are also behind the terms "computer-aided molecular design" and "drug design" where one is often looking for molecules with specific biological properties. 
Also beyond pharmaceutical research computational chemistry and chemoinformatics are widely applied, for example for the development of novel biotechnological processes and products.

Chemoinformatics databases gather resources on biochemically active compounds and their interactions

  • Small molecule databases 
  • Natural compound databases 
  • Natural product databases
  • Drug-drug interaction databases 
  • Secondary metabolite biosynthetic databases
  • Chemical-transporter interaction databases
  • ADME databases 
  • Bioactivity databases
  • Adverse drug reactions databases
  • Compound toxicity databases 
  • Drug pathways databases
  • MicroRNA pharmacogenomic databases 
  • miRNA pharmacogenomic databases
  • Toxicogenomics databases
  • Pharmacogenetics databases
  • Drug resistance databases
  • Clinical trial databases
  • RNA-ligand interactions databases
  • Drug metabolism databases
  • Drug sensitivity databases
  • Drug repositioning databases
  • Chemical structure databases
  • Molecular simulation databases
  • Organic chemistry reactions databases

How technology impact chemical industry?

Technology changing chemical industry

The latest technology is already changing the chemical industry. USD Computer modelling and big data, 
even modern theory on industrial processes are having an impact. 
how is technology being used by chemical manufacturing companies.

1. Cloud Storage 
Significantly, cloud data storage enables massive cost savings and increased efficiencies and customer satisfaction.

2. Maintenance Analytics
By applying advanced analytics chemical manufacturers have begun to use their data to get the most out of their assets. 
Predictive-maintenance systems can avoid problems that would remain unseen when using traditional techniques.

Simazine - Chemryt

Simazine is a selective pre-emergent herbicides used to control a wide variety of annual and perennial grasses and broadleaf weeds.Simazine has also been used to control weeds on turfgrass and as a non-selective form of weed control when used at higher rates on industrial sites.
When bermudagrass is mostly dormant, you can apply non-selective herbicides like glyphosate or glufosinate . 
Simazine or flumioxazin will also offer post control of annual bluegrass
simazine and all other soil active herbicides are watered in within 48 hours of application in a way that does not cause movement off site or past target zone in soil.

Chemical Name - Simazine
Mol Weight - 201.66
Smiles - CCNc1nc(Cl)nc(NCC)n1


Propanil -

Propanil is a post-emergence herbicide currently being assessed for safety and efficiacy by the EU. It is moderately soluble in water and has a low volatility. It is not expected to leach to groundwater and is not usually persistent in soil or water systems. It is moderately toxic to mammals and no evidence of serious human health impact have been identified. It is, however, moderately toxic to most fauna and flora.A
