Sales of Biofuels exceeded $ 12 billion in 2003 worldwide. High growth in 2004. The greening Automotive Industry in China.
In some countries the costs for biofuel are today lower than traditional oil and that’s only the beginning of a new development for many countries to be oil-free in the next 30 years. Nanobiotechnology will improve the biomass production by shaping molecules to design “energyplants” and optimize the biotechnology process. Nanotechnology and converging biotechnology increase the energy potential in the plants used for biofuel with more than 60 percent.
The worldmarket for biofuel exceeded $ 12 billion in 2003 and is expected to grow to $ 34 billion in 2015. Brasil is worldwide market leader representing 45 percent, the USA accounting for 20 percent, soon China will be number 3 with the aim to be number 2 in several years with the help of Brasil and wants to be oil-free by 2030 according to a new study of hkc22.com. The chinese government program includes a $ 200 million r&d budget, low interest loans, and different subsidies. All car companies in China follow the trends and present cars using biofuel, electricity or hybrid technologies . Europe is following and passed the start-up stage. The transition takes a long time but the time has come for the technologies and the market too. Increasing oilprices will speed up the developments.

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
