*With a budget/without a budget*
Yesterday was an awesome day (10.10.2018). Students from public and private Universities in Colombia (my native country) marched for a better financing to public universities. In short words,  there is a problem with the money that is earmarked for these sectors which is not enough to cover the actual requirements to the normal operation of the universities. A banner from today ☺

Pure nitric acid barely reacts with copper metal, due to an effect called passivation. However, when water is added, the acid is diluted and passivation no longer occurs. 
The nitric acid can then freely attack the metal, forming blue copper nitrate and a lot of nitrogen dioxide gas.

A full explanation  of this is given in my video on nitric acid on YouTube.

A physics lecture 90 years ago: The lecturer, Paul Scherrer, was appointed Professor of Experimental Physics at ETH Zurich in 1920 at the age of only 30. As early as 1916, together with Peter Debye, temporarily Professor at ETH, he developed an experimental method for determining the structure of crystals using X-rays. In 1936, Debye was awarded the Nobel Prize in Chemistry for this method, which is still known today as the Debye-Scherrer method.

The Nobel Laureates in Chemistry 2018 have harnessed evolution and further advanced it in their laboratories. 
One half of this year’s Nobel Prize in Chemistry is awarded to Frances H. Arnold. In 1993, she conducted the first directed evolution of enzymes, which are proteins that catalyse chemical reactions. Since then, she has refined the methods that are now routinely used to develop new catalysts. The uses of Arnold’s enzymes include more environmentally friendly manufacturing of chemical substances, such as pharmaceuticals, and the production of renewable fuels for a greener transport sector. 
The other half of this year’s Nobel Prize in Chemistry is shared by George P. Smith and Sir Gregory P. Winter. In 1985, Smith developed an elegant method known as phage display, where a bacteriophage – a virus that infects bacteria – can be used to evolve new proteins. 
Winter used phage display for the directed evolution of antibodies, with the aim of producing new pharmaceuticals. The first one based on this method, adalimumab, was approved in 2002 and is used for rheumatoid arthritis, psoriasis and inflammatory bowel diseases. Since then, phage display has produced antibodies that can neutralise toxins, counteract autoimmune diseases and cure metastatic cancer.

The inventions being honoured by this year’s Nobel Prize in Physics have revolutionised laser physics. Extremely small objects and incredibly fast processes now appear in a new light. Not only physics, but also chemistry, biology and medicine have gained precision instruments for use in basic research and practical applications.

Arthur Ashkin invented optical tweezers that grab particles, atoms and molecules with their laser beam fingers. Viruses, bacteria and other living cells can be held too, and examined and manipulated without being damaged. Ashkin’s optical tweezers have created entirely new opportunities for observing and controlling the machinery of life.

Gérard Mourou and Donna Strickland paved the way towards the shortest and most intense laser pulses created by mankind. The technique they developed has opened up new areas of research and led to broad industrial and medical applications; for example, millions of eye operations are performed every year with the sharpest of laser beams.

BREAKING NEWS
The Nobel Assembly at Karolinska Institutet has today decided to award the 2018 Nobel Prize in Physiology or Medicine jointly to James P. Allison and Tasuku Honjo “for their discovery of cancer therapy by inhibition of negative immune regulation.” Cancer kills millions of people every year and is one of humanity’s greatest health challenges. By stimulating the inherent ability of our immune system to attack tumour cells this year’s Nobel Laureates have established an entirely new principle for cancer therapy. 
James P. Allison studied a known protein that functions as a brake on the immune system. He realised the potential of releasing the brake and thereby unleashing our immune cells to attack tumours. He then developed this concept into a brand new approach for treating patients. 
In parallel, Tasuku Honjo discovered a protein on immune cells and, after careful exploration of its function, eventually revealed that it also operates as a brake, but with a different mechanism of action. Therapies based on his discovery proved to be strikingly effective in the fight against cancer. 
Allison and Honjo showed how different strategies for inhibiting the brakes on the immune system can be used in the treatment of cancer. The seminal discoveries by the two laureates constitute a landmark in our fight against cancer. .

Nitrogen filling in slow motion!🐌📹I'm setting up a reaction that needs inert atmosphere.👽 For that I've evacuated the air in the vial and then I added nitrogen with a ballon.🎈💊 Can you see the content (catalyst, base, etc) jumping because the N2 pressure?😁
Have a great week!!😎✌
