External 2TB HDD Buffalo HD-PCFU3-C

06.01.2015

The Japanese company Buffalo announced the release of a series of external hard drives HD-PCFU3-C. The series includes models with a capacity of 500 GB, 1 and 2 TB, offered in black and white versions of the external design, that is, a total of six products.

The drives are equipped with a USB 3.0 interface, which is used for both data exchange and power supply. Includes 50cm USB cables.

The dimensions and weight of the devices depend on the size of the hard drive. 2TB drives with dimensions of 76 x 19,5 x 115mm weigh 225g, 1TB drives with dimensions of 76 x 14 x 115mm weigh 165g, and 500GB drives with dimensions of 76 x 11,5 x 115mm weigh 145

In the Japanese market external HDD Buffalo HD-PCFU3-C should appear in early January. Models PCF2.0U3-GBC and HD-PCF2.0U3-GWC with a capacity of 2 TB will cost approximately $165, models HD-PCF1.0U3-BBC and HD-PCF1.0U3-BWC with a capacity of 1 TB are priced at $110, and the most affordable are the 500 GB HD-PCF3U500-BC and HD-PCF3U500-WC models cost about $90.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

A new type of strange quasicrystals 17.01.2019

Physicists and chemists at Brown University have for the first time created a self-assembling quasi-crystal lattice, consisting of quantum dots of a strictly defined shape. Similar quasicrystalline lattices have already been described mathematically and calculated in the course of complex computer simulations more than once, but no one has previously been able to demonstrate their creation, as they say, live.

We remind our readers that crystals are structures consisting of homogeneous components and possessing symmetry in one or more spatial coordinates. In other words, if we take any section of the crystal and shift it to a certain distance along the axis of symmetry, then the structure of the shifted section will completely coincide with the structure of the "unshifted" section. Quasicrystals do not have such a symmetry, their components are arranged in space in an ordered manner, but the structure of a quasicrystal does not repeat itself.

The mathematical description of quasicrystals is quite easy to create, but, as previously thought, the creation of aperiodic crystal structures in reality is impossible. Some time ago, scientists have already observed signs of the existence of quasi-crystals in aluminum alloys that have gone through a complex process of synthesis and heat treatment, and this fact was the first confirmation of the possibility of their existence. At present, the fact of the existence of quasicrystals is considered already proven, and they are considered a new potentially useful type of material.

So let's get back to the material created at Brown University. Interestingly, scientists initially did not even think about quasicrystals, their task was to find new methods for building macrostructures from nanosized components. One of the types of components was a pyramidal quantum dot, a tetrahedral particle, about one nanometer in size. Preliminary calculations have shown that such a shape will allow "packing" in a certain volume of space a greater number of such particles than particles of a traditional spherical shape.

Tetrahedral particles had one more feature, they behaved and interacted with neighboring particles in different ways, depending on their current spatial orientation. And as a result of this, after a while, all the particles spontaneously ordered, creating a complex structure, which is known as a quasi-transparent superlattice.

Electron microscope studies of this structure have shown that the particles form decagonal patterns, united by a symmetry of a kind never found in traditional crystals. The only exception is the boundaries of the material, where, in order to optimally fill the space, the particles are combined into patterns with fewer corners.
