The situation regarding titanium is paradoxical. On the one hand, titanium is found in abundance in the natural environment: in terms of natural occurrence in the earths crust, the element is the third among all metals, directly following iron and aluminium. In industry, particularly in metallurgy it is used very rarely, about one hundred times less than aluminium. This happens in spite of the outstanding properties of titanium: it is lightweight, fast, heatproof and chemically stable. But it is too expensive as it is very difficult to extract it from minerals, and the raw materials for its production are extremely expensive.
It came to having to purchase titanium dioxide from abroad. It is used as a basis for titanium white, and the production of plastics, paper and even cosmetics. There are enough deposits in Russia; the problem is that Russia has not yet managed to establish the production of high-quality raw titanium.
This stumbling block will probably be removed soon with the help of the technology developed in the Baikov Institute of Metallurgy and Material Authority, Russian Academy of Sciences(IMET RAS), in the laboratory of Professor Reznichenko by G.B. Sadykhov, Doctor of Science (Engineering).

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
