Bright colored LEDs from Cree

29.05.2013

Cree has announced the market availability of XLamp XP-E2 color LEDs. According to the developers, the new products are 88% brighter than alternative high-power solutions.

XLamp XP-E2 LEDs use SC Technology. They are optically compatible with their predecessors, the XP-E, in the same compact form factor (3,45mm x 3,45mm). At the same time, their brightness per 1 W and $ 1 is much higher.

XLamp XP-E2 devices are characterized by a light output of 109 lumens for blue, 253 lumens for green, 203 lumens for yellow, 193 lumens for red-orange. Cree is currently offering trial samples of its new LEDs, with mass production starting soon.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Unmanned amphibious aircraft to deliver mail to the island 05.07.2019

The Chinese company UVS Intelligence System tested its unmanned amphibious aircraft by delivering mail to one of the islands of the Shensi archipelago.

The U650 unmanned seaplane, developed by UVS Intelligence System, is based on the Spanish Colyaer Freedom S100 ultralight seaplane. The wingspan of the U650 is 12,4 meters. The device is capable of flying at a speed of 190 kilometers per hour.

Flightglobal, UVS Intelligence System tested the U650 - delivering mail to one of the islands of the Shanxi archipelago. As part of the test, the U650 flew from Shanghai to the island with a load of 200 kilograms, spending 52 minutes in the air (delivery of mail by boat, by comparison, takes about two to three hours).

Technology developed to extract water from the moon
06.07.2019
Water is an important resource for space exploration because it can be chemically separated into hydrogen and oxygen, which can then be used as rocket fuel. The possibility of refueling rockets on the Moon will open up new horizons for humanity and reduce the cost of flights beyond the orbit of the satellite.

In the past, scientists have already proposed to start mining the lunar soil: using heavy equipment, dig out ice blocks from the regolith and melt water from them on the surface. However, Phil Metzger and Julie Brisset, who received the contract, have a different idea. They propose to drill deep wells through which heat will be pumped. So you can melt the water frozen in the regolith, which will rise up in the form of steam. This method requires less equipment, it is simpler and more reliable.

"When it comes to delivering cargo into space, mass matters," Metzger said. Representatives of the United Launch Alliance agree with this, who considered this method quite realistic and cost-effective.

"Getting propellant on the Moon could be significantly cheaper than transporting it from Earth with its high gravity," said Bernard Cutter, chief scientist at United Launch Alliance. "This, in turn, will reduce the cost of flights by a factor of 5."

The main problem facing scientists now is to determine the correct geometry of the holes in order to increase the volume of the heated zone and the time during which it will retain heat.
