• Nanotechnology imaging breakthrough
  

  A team of researchers has made a major breakthrough in measuring the structure of nanomaterials under extremely high pressures. For the first time, they developed a way to get around the severe distortions of high-energy X-ray beams that are used to image the structure of a gold nanocrystal. The tec more

• Oxygen molecule survives to enormously high pressures

  Using computer simulations, a RUB researcher has shown that the oxygen molecule (O2) is stable up to pressures of 1.9 terapascal, which is about nineteen million times higher than atmosphere pressure. Above that, it polymerizes, i.e. builds larger molecules or structures. “This is very surprising” s more

• 1,9 million EU grant for Mikhail Eremets from the Max Planck Institute for Chemistry

  Dr. Mikhail Eremets from the Max Planck Institute for Chemistry has been awarded an Advanced Grant from the European Research Council end of October. The sum of € 1.9 million was granted for exploring conductive and metallic hydrogen. In his project, Eremets plans to study molecular hydrogen under e more

• Particle sizing with static laser scattering
  

  When determining particle sizes a wide variety of techniques are used in which sieving may be the most popular. Sieving is a relatively simple technique, despite the fact that of course different instrumental approaches can be used. The main advantages of sieving are the low price of the instrumentation and the fact that different fractions of the original sample can be prepared for further use. On the other hand, sieving is very time consuming and yields results only for a very limited number of particle sizes. Results from sieving typically vary due to several factors: the method of moving the sieve, the period of operation, the number of particles on the sieve and some physical properties such as shape or stickiness of the sample. In addition, the actual size of the mesh gaps of the sieves can have large variations from the nominal size more

• On-line particle analysis in wet processes
  

  Fully automated particle size measurement technology integrated with existing plant control platforms for ease of use has the potential to deliver numerous benefits. At plants where a switch to on-line analysis has been made it is frequently easier or possible to: more

• A microfluidic platform for generating large-scale nearly identical human microphysiological system arrays

  This paper reports a polydimethylsiloxane microfluidic model system that can develop an array of nearly identical human microtissues with interconnected vascular networks. The microfluidic system design is based on an analogy with an electric circuit, applying resistive circuit concepts to design pr more

• Pressure dependent photolysis quantum yields for CH3C(O)CH3 at 300 and 308 nm and at 298 and 228 K

  The quantum yield of formation of CH3 and CH3CO in the pulsed laser photo-excitation of acetone at 300 and 308 nm was investigated at several pressures (60 to 740 Torr) and at either 298 or 228 K. The organic radicals generated were monitored indirectly following conversion (by reaction with Br2) to more

• Germanium-Tin Alloy Nanocrystals for High-Performance Lithium Ion Batteries

  Germanium-tin (Ge1-xSnx) alloy nanocrystals were synthesized using a gas-phase laser photolysis reaction of tetramethyl germanium and tetramethyl tin. A composition tuning was achieved using the partial pressure of precursors in a closed reactor. For x < 0.1, cubic phase alloy nanocrystals were excl more

• Ukraine Petrochemicals Report Q2 2012

  Ukrainian petrochemicals output performed consistently well throughout much of 2011 with primary plastic output up 25% y-o-y to 550,500 tonnes, according to BMI’s latest Ukraine Petrochemicals Report. Production was up on pre-crisis levels, despite the lacklustre performance of the domestic market. more

• South Africa Petrochemicals Report Q4 2012

  The latest South Africa petrochemicals report examines the way in which South Africa’s basic petrochemicals producer Sasol is defending its market position as it competes with an influx of cheap products from Asia, while attempting to maintain strong operating margins. We also analyse the key challe more

• Colombia Agribusiness Report Q3 2012

  BMI View: In May, the long-stalled free trade agreement (FTA) between Colombia and the US finally was put into action. The FTA was first signed in 2006 but had not been ratified owing to continuing concerns in the US over Colombia's human rights record. The pact eliminates tariffs on 77% of agricult more
