potato starch

29.01.2010

Potatoes containing only one type of starch - amylopectin, were bred by German bioengineers.

There are two types of starch in ordinary potato tubers: water-insoluble amylopectin and soluble amylose. It is the first that finds application in industry - they process paper to make it smooth, cover threads and use it to make all kinds of sticky binders. In general, the Germans alone consume half a million tons of this substance per year. And they are forced to spend a lot of effort in order to separate it from amylase.

Scientists from the Fraunhofer Institute for Molecular Biology and Applied Ecology, led by Professor Dirk Prüfer, decided to make life easier for starch manufacturers and grow potatoes with only amylopectin. To do this, they caused mutations in potato seeds, and then, analyzing the first leaves of seedlings, they tried to find those that would have the correct genome: those with suppressed amylose genes.

Luck smiled at them after 2748 experiments. If scientists used traditional breeding methods, the work would have dragged on for years, but thanks to the achievements of genomics, it was possible to solve it much faster. Seedlings were obtained from a successful plant - and in the fall of 2009, the first 100 kilograms of potatoes with purely amylopectin tubers went for experimental processing.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

New family of multi-channel DACs 27.02.2009

Maxim Integrated Products has introduced a new family of quad (MAX5134/MAX5135) and dual (MAX5136/MAX5137) 16-bit and 12-bit DACs that are both pin- and software-compatible. These DACs offer a combination of higher accuracy, integration and smaller footprint than competing products.

Energy saving is becoming a critical requirement for all systems today, not just for battery powered devices. In sleep mode, the MAX5134M AX5137 DACs consume less than 300nA. Four 12 or 16-bit DACs can operate at an average current of 2,5 μA. With a built-in high-precision voltage reference, these DACs provide designers with unparalleled flexibility to change the number of channels and resolution with little or no device redesign.

Each DAC channel can be individually disabled for better power management. The high linearity (+8 LSB INL for 16-bit and +1 LSB INL for 12-bit DAC) and flexibility of these DACs make them ideal for industrial control systems and portable instrumentation such as communication systems, programmable logic controllers, closed servo loops and automated control systems.

Other applications for these DACs include: automatic tuning and adjustment, control of power amplifiers, data acquisition systems, programmable voltage and current sources.
