How Quantum Dots and Ultra HD Are Changing the Way TV Displays Are Made

Chances are you’re familiar with HDTV. Most of us have one of these in our living rooms. In fact, according to a recent study, more than 80% of US residents probably have at least one HDTV in their homes. And there’s a good possibility these sets are LCDs. They may be a few years old but they’re thin, look great hanging on the wall and basically do their job well. Some of these HDTVs also have 3D capabilities but the required glasses have long been lost to the couch cushions or the dog ate them or they just never made it out of the packaging due to lack of content support by broadcasters.

Making 3D Objects Disappear

Invisibility cloaks are a staple of science fiction and fantasy, from Star Trek to Harry Potter, but don’t exist in real life. Or do they? Scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have devised an ultra-thin invisibility “skin” cloak that can conform to the shape of an object and conceal it from detection with visible light. Although this cloak is only microscopic in size, the principles behind the technology should enable it to be scaled-up to conceal macroscopic items as well.

New Spectroscopy Method Captures Reactions in Photosynthesis

A new spectroscopy method is bringing researchers at Rensselaer Polytechnic Institute (RPI) closer to understanding – and artificially replicating – the solar water-splitting reaction at the heart of photosynthetic energy production. Understanding the step-by-step mechanism of photosynthesis could lead to methods of producing highly efficient solar energy. The spectroscopy method, a novel use of “2D HYSCORE,” is able to capture the reactions that split water and hydrogen peroxide in metal-containing proteins or metallo- enzymes in nature.

New Solar Energy Storage Technique Could Boost Solar Cell Usage

Researchers at Missouri University of Science and Technology have developed a relatively inexpensive and simple way to split water into hydrogen and oxygen through a new electrodeposition method. The method produces highly efficient solar cells that can gather solar energy for use as fuel. The research, sponsored by the U.S. Department of Energy, could lead to a sizable increase in the amount of hydrogen available for fuel usage.

Products of Tomorrow: October 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Modern CMOS Cameras as Replacements for CCD Cameras

Many users of CCD sensors are asking about the advantages of the latest CMOS sensors, particularly if they have been using CCD-based cameras. The two sensor technologies, a comparison of the new CMOS sensors and existing CCD sensors, and tips for when it makes sense to select a new camera with CMOS sensors are provided in this article, as well as what to expect after integration.

Underwater Adhesives Retrofit Pipelines with Advanced Sensors

NASA-developed sensors and adhesion methods equip pipelines and tension legs that hold offshore platforms upright for safety monitoring. By the time the gas you fill your car with hits the engine, it’s been through quite a journey. An oil platform in the Gulf of Mexico, for example, might need to be built over water with a depth of 10,000 feet. Long pipelines under high pressures face a multitude of dangers. Some are structural, such as natural vibrations generated by ocean currents and waves that bend the pipes back and forth — a phenomenon known as vortex-induced vibration, which is similar to the sway of a car antenna wire when driving on the highway. Other risks lie inside the pipe, where the right combination of pressure and temperature causes the hydrates in the oil to precipitate, forming a dirty, snowball-like mass that quickly grows.
