Chip manufacturers invest in production expansion against persistent chip deficiency

The world-growing contract manufacturer TSMC invests 2 billion euros in its production capacity. The fourth gray memory chip manufacturer Nanya builds a new chip factory in Taiwan for nearly 9 billion euros. Both should operate the further growing demand for semiconductors. Western Digital and Micron, on the other hand, are looking for the use of Japanese Kioxia, the second grave manufacturer of flash memory chips.

The Taiwanese memory chip manufacturer Nanya Technology has announced to invest around 8.8 billion euros in the construction of a new semiconductor factory in northern Taiwan. The construction should start this year and be completed in the city’s year. From 2024 DRAM chips in 10 nanometer technology are to be produced using extreme ultraviolet exposure.

Nanya is the fourth-grayed DRAM chip manufacturer in the world. With a market share of just under 3 percent, however, Taiwaners are far behind the Korean industry drivers Samsung and SK Hynix, which come on market shares of 42 and 30 percent. Since the DRAM market is expected to grow more than 50 percent by theest year alone, Nanya wants to reduce the luck with the market operators with this coarse investment.

Mazda reduces precious metal content in the catalyst

Leverkusen, 12. January 2009 – The precious metals platinum, rhodium and palladium are as important as valuable components of modern three-way catalysts for gasoline engines. A saving of 70 percent of the amount of material reports Mazda through the use of nanotechnology in the Cat. The technique will first be used in the year of 2009 in the new Mazda 3 with 2.0-liter gasoline engine and then gradually in other models.

Metal clump in the Cat

In conventional catalysts, the precious metals are relatively loosely bound to the base material. This inevitably leads to a merger of precious metals to coarse lumps. The catalytically active surface is thereby reduced, the catalyst power decreases. Nevertheless, to achieve a sufficient effect, more precious metal is simply used in conventional kats. Smart is with nanotechnology. Mazda developed a new strand material structure and puts on very small precious metal particles: they have a diameter of less than five nanometers. Thus, only 0.15 instead of 0.55 grams of precious metal per liter of carrier material are needed.

Conversion rate is retained

Nevertheless, the conversion rate for the entire service life itself is to be maintained even under sharpest operating conditions in full, promises the manufacturer. Even the conditions for "Super Ultra-Low Emission Vehicles" (Su-LEV) in Japan are thus from Mazda 3 2.0 undercut. Emissions are even 75 percent below the values demanded by the legislator, Mazda.

Amd starts ryzen 3000c for chromebooks

AMD expands his portfolio of mobile processors, especially for Chromebooks: Above the powerful (and continued) A4 and A6 models now add two Athlon and three Ryzen. The latter does not belong to the current Ryzen-4000 generation with ZEN-2 technology, but still comes from the 3000er series series. Accordingly, there are a maximum of four Zen / Zen + type cores, the production takes place with 12- and 14 nanometer structures.

AMD’s new Chromebook CPU

The differences to known Ryzen-3000 models are only in the name: The Ryzen 7 3700C has the same technical data as the well-known Ryzen 7 3700U. The term ending on -c should help, according to the AMD, in the search for Chromebooks imagined CPU models then actually only find chromebooks.

Lenovo yoga slim 7 pro: 14-inch notebook with ryzen 9 4900h and 16: 10 display

Lenovo updates its upper-class notebook series Yoga with current processors from AMD and Intel. The yoga slim 7 Pro stands out: it is one of the few advised with Ryzen-4000h combined processors without additional graphics chip – in Germany for the first time with the top model Ryzen 9 4900h. Other manufacturers pair the CPUs with GeForce or in-house Radeon GPUs.

Otherwise, the yoga slim 7 Pro makes a lot on the paper: up to 16 GB of flotter LPDDR4X-RAM in the dual channel (Ryzen 4000h support LPDDR4X-4266), high quality display options and USB 3.2 GEN 2 (10 GBIT / S) with Power Delivery and DisplayPort-1.4-signal via two type C connections.

High-rotting 14-inch screen

A 14-inch display is used in high 16: 10 format "Wide viewing angles" – Behind it is usually IPS technology. The basic model represents 2240 × 1400 pixels and lights up with 300 cd / m². A more expensive variant Lost with 2880 × 1800 pixels and creates 400 CD / m², but is not available with Matter coating. Both options cover the SRGB color space 100 percent.

18-Tbyte hdds thanks to epmr: wd hard drives available

German handlers deliver the first three hard disks with a capacity of 18 TByte. The WD Gold 18 TByte and Ultrastar DC HC550 18 TByte are sister models from Western Digital with SATA 6G ports. The manufacturer also offers the DC-HC550-HDD with SAS 12G as an alternative. All rely on Conventional Magnetic Recording (CMR), helium filling and a 512 MByte coarse DRAM cache.

Due to the same technology, the specifications are very similar: The WD Gold 18 TByte transfers up to 269 MByte of data. Both are rated for 550 TBytes of write volume per year with a five-year warranty. Western Digital estimates the Mean Time Between Failures (MTBF) to be 2.5 million hours. The Ultrastar model is marketed by the manufacturer for use in data centers, while WD Gold is aimed at end customers and smaller server operators.

ePMR increases capacity

Both hard disks use the Energy-enhanced Perpendicular Magnetic Recording (ePMR) technology as the first representative of the Energy-Assisted Magnetic Recording (EAMR) family, which Western Digital explains in a technical documentation: An electric current is conducted into the write head to generate an additional magnetic field and thus reduce the so-called jitter.

Plain text: you killed the electric car

My first and at the same time penultimate visit to the IAA happened in 1991. Even then, I was mainly interested in two things: firstly, how fast the car could drive? Secondly, how else can the auber be powered by diesel or gasoline?? For the latter, the trade show at that time already presented some technically advanced ideas. Both Mercedes and BMW showed prototypes of hydrogen engines, because the idea of a hydrogen economy already had this attraction at that time, which helps it to this day to always new life despite all adversities. The prototypes burned hydrogen gas directly in modified reciprocating engines instead of fuel cell stacks, but the basic infrastructure problems were little different. At the same time BMW showed the compact car E1, a surprisingly finished looking electric car.

"They’ll want that …"

The E1 looked so close to series production because BMW had actually designed the show car with series production in mind. In the nineties, there were briefly serious efforts to make individual transport more efficient. These resulted, for example, in Audi’s large A2, which the E1 not coincidentally looks very similar to: as small as possible (it was only 3.46 meters long), at the same time as much space as possible inside, as light as possible built on an aluminum chassis and, despite all safety requirements, with a lot of glass for active safety from a good view.

The Munich engineers also did their homework prudently from a technical point of view. In the floor of the E1 was a sodium-sulfur battery, an experimental use of this storage technology in the 1990s, which is now used in storage power plants. Since this type of battery operates at temperatures above 300°C, it is no longer used in electric cars. BMW put at least 20 kWh into the little car. This amount of energy should be sufficient for driving distances of "up to 200 km".

Search for exoplanets: nasa telescope tess delivers the first 2200 candidates

The NASA Space Telescope Transit Exoplanet Survey Satellite (TESS) has found more than 2200 possible exoplanets on its primary emission, including hundreds that could be seen as rock plans of the earth. According to the evaluation of the data scientists, according to the evaluation of the data, according to the fact that many of the candidates were allowed to be confirmed and the number of well-known exopplanes significantly increases. Because the stars examined by TESS are relatively bright, it is also expected that there will be a number of candidates for successors about the atmosphere.

Kepler’s successful successor

Tess was launched in April 2018 as a successor to the successful ExoplanetenJager Kepler. During Kepler, however, during his main mission has examined a narrow sky area in detail, Tess almost) looks for the entire sky – but every partial area short. Tess takes a 24-degree 96 ° coarse sky region for at least 27 days each for at least 27 days and asks the stars to periodic blackouts. The ways of exoprlayers, which circle their star in a few days, many of them much more closely than Keplers finds.

With the presentation of the database of light curves, which are considered candidates for possible exoplanets, but only another partial step is made of the search. The collection is a kind of to-do list, explores research director Natalia Guerrero from the Massachusetts Institute of Technology (with) – "Enter with 2000". The science community is now deepening in it and would expect years to be busy. Artist space telescopes such as the YWST of NASA or Ariel of ESA have been safely analyzed in detail and provide a lot of insights over exoplanets. First, however, the candidates had to be confirmed, for about 120 that had already been possible.

Pilot project: autonomous shuttle bus drive in magdeburg

Autonomously driving buses will improve the connection at the existing public transport in the future. In Magdeburg, the Otto-von-Guericke-Universitat has begun the preparations for a corresponding pilot project this week. For this purpose, the researcher team made first driving tests with the French minibus EZ10, which offers space for up to Zwolf Fahrzasten, on the edge of the Magdeburg Old Town.

At the attempts this week, the planned test track will first be measured, said Sonke Beckmann from the Institute for Logistics and Material Flow Technology. On Wednesday, the scientist team also tried technical details, such as the automatic ramp for rolling chairs, which should allow barrier-free operation. "From the afterest week, the training of the employees then starts and then the test operation begins", said Beckmann. In the test operation, which should start from August, then interested parties can be made by the intelligent driverless minibus between the Seumestrabe over the star bridge in the city park and back. When exactly the 2.3-kilometer route can be driven, is not fixed yet.

Autonomous moving shuttle

The 1850 kg lightweight minibus EZ10 can, according to the French manufacturer EasyMile Zwolf Fahrgaste (EasyMile speaks partly also of 15 tracks) with a payload up to just under a ton. There are six seats available. Depending on the local provisions, it may be that only the seats are occupied thirst. The vehicle drive in automated operation up to 25 km / h quickly and is suitable for routes up to 5 kilometers long. Between 6 and 10 hours hold the battery through.

Expert council: germany must build quantum computers in a few years

An expert commission used by the Federal Government has one "Roadmap Quantum Computing" created. The 16 representatives from business and science demand: Germany MUSSE in FUF to ten years "in combination with the European partners will be able to build and operate an application-related quantum computer at the top of international competition".

"Our milestone: International Competitive Quantum Computer with at least 100 individually controllable qubits and scaling potential to 500 qubits", it is called in the paper that has become published now. The first rough is seen as a prerequisite for a performance quantum computer that can overflow conventional processes.

Quantum advantage for practice-relevant applications

Google has indicated, already with 53 qubits to have achieved the desired quantum superiority. IBM took the quantum processor Hummingbird with 65 qubits last year and pages a 1121 qubit with 1121 quibs for 2023. The information content in a qubit is generally high thanks to its intermediate positions than in one bit, which is either 0 or 1.
