All of the technology is nearly ready for megawatt space based laser systems for science and planetary defense

Posted by in categories: electronics, energy, science, space travel

California Polytechnic State University researchers propose a system capable of probing the molecular composition of cold solar system targets such as asteroids, comets, planets and moons from a distant vantage.

Their concept utilizes a directed energy beam to vaporize or sublimate a spot on a distant target, such as from a spacecraft near the object. With sufficient flux, our published results indicate that the spot temperature rises rapidly, and evaporation of materials on the target surface occurs (Hughes et al., 2015; Lubin and Hughes, 2015; Lubin et al., 2014). The melted spot serves as a high-temperature blackbody source, and ejected material creates a molecular plume in front of the spot. Molecular and atomic absorption of the blackbody radiation occurs within the ejected plume. Bulk composition of the surface material is investigated by using a spectrometer to view the heated spot through the ejected material. They envision a spacecraft that could be sent to probe the composition of a target asteroid, comet or other planetary body while orbiting the targeted object. The spacecraft would be equipped with an array of lasers and a spectrometer, powered by photovoltaics. Spatial composition maps could be created by scanning the directed energy beam across the surface. Applying the laser beam to a single spot continuously produces a borehole, and shallow sub-surface composition profiling is also possible.

Their initial simulations of laser heating, plume opacity, material absorption profiles and spectral detectivity show promise for molecular composition analysis. Such a system has compelling potential benefit for solar system exploration by establishing the capability to directly interrogate the bulk composition of objects from a distant vantage. They propose to develop models, execute preliminary feasibility analysis, and specify a spacecraft system architecture for a hypothetical mission that seeks to perform surface molecular composition analysis and mapping of a near-earth asteroid (NEA) while the craft orbits the asteroid.

University of Tokyo researchers have created an ultrathin and ultraflexible organic e-skin that supports PLED and OLED displays.

Researchers from the University of Tokyo have created a protective layer of organic material that’s ultrathin and ultraflexible. And the have demonstrated the material’s usefulness by making an OLED display that’s air-stable. This opens the possibility of developing better electronic skin displays, the next major leap in wearable technology.

Clothes that Transmit Digital Data Are Coming

Posted by in categories: biotech/medical, electronics, health, mobile phones, neuroscience, wearables

Imagine shirts that act as antennas for smartphones or tablets, workout clothes that monitor fitness level or even a flexible fabric cap that senses activity in the brain!

All this will soon be possible as the researchers working on wearable electronics have been able to embroider circuits into fabric with super precision — a key step toward the design of clothes that gather, store or transmit digital information.

“A revolution is happening in the textile industry. We believe that functional textiles are an enabling technology for communications and sensing and one day, even for medical applications like imaging and health monitoring,” said lead researcher John Volakis from Ohio State University.

Samsung’s flagship KS9800 is bold, beautiful, and wicked smart

Posted by in categories: electronics, virtual reality

Wicked nice — however, I cannot wait to see SamSung leverage Q-Dots (QD) for VR.


It’s Samsung’s best 4K UHD TV yet, and not just because it has stunning picture quality. It’s also the smartest, easiest-to-use TV we’ve seen in some time.

New hybrid inks permit printed, flexible electronics without sintering

Posted by in categories: computing, electronics

Research scientists at INM have combined the benefits of organic and inorganic electronic materials in a new type of hybrid inks. This allows electronic circuits to be applied to paper directly from a pen, for example.

The electronics of the future will be printed. Flexible circuits can be produced inexpensively on foil or paper using printing processes and permit futuristic designs with curved diodes or input elements. This requires printable electronic materials that can be printed and retain a high level of conductivity during usage in spite of their curved surfaces. Some tried and tested materials include organic, conductive polymers and nanoparticles made of conductive oxides (TCOs). Research scientists at INM – Leibniz-Institute for New Materials have now combined the benefits of organic and inorganic electronic materials in a new type of hybrid inks. This allows electronic circuits to be applied to paper directly from a pen, for example.

HRL to develop inertial sensor tech for DARPA

Posted by in categories: electronics, transportation

Could this sensor technology revolutionize how auto and other navigation technology looks in the future?


The Defense Advanced Research Projects Agency (DARPA) has awarded HRL Laboratories $4.3 million to develop vibration- and shock-tolerant inertial sensor technology that enables future system accuracy needs without utilizing GPS.

While GPS provides sub-meter accuracy in optimal conditions, the signal is often lost or degraded due to natural interference or malicious jamming.

HRL Laboratories, based in Malibu, California, is a corporate research-and-development laboratory owned by The Boeing Company and General Motors specializing in research into sensors and materials, information and systems sciences, applied electromagnetics and microelectronics.

“DNA base pairing has been used for many years to direct the arrangement of inorganic nanocrystals into small groupings and arrays with tailored optical and electrical properties. The control of DNA-mediated assembly depends crucially on a better understanding of three-dimensional structure of DNA-nanocrystal-hybridized building blocks. Existing techniques do not allow for structural determination of these flexible and heterogeneous samples.”

Smartphones should fully embrace the dual-camera bandwagon

Posted by in categories: electronics, mobile phones

One of the biggest rumors surrounding the iPhone 7 is that Apple is adding a second camera module (at least on the Plus model), and it makes a lot more sense than you might realize.

After all, other manufacturers have already caught on. LG’s G5 comes with a ultra-wide angle lens, Huawei’s new P9 sports a dedicated black-and-white camera, and HTC beat everyone to the punch with the One M8’s depth-sensing camera a couple of years ago.

Our biggest ever edition of TNW Conference is fast approaching! Join 10,000 tech leaders this May in Amsterdam.

Quantum dots enhance light-to-current conversion in layered metal dichalcogenide semiconductors

Posted by in categories: computing, electronics, quantum physics, solar power, sustainability

Improving light-sensing devices with Q-Dots.


Harnessing the power of the sun and creating light-harvesting or light-sensing devices requires a material that both absorbs light efficiently and converts the energy to highly mobile electrical current. Finding the ideal mix of properties in a single material is a challenge, so scientists have been experimenting with ways to combine different materials to create “hybrids” with enhanced features.

In two just-published papers, scientists from the U.S. Department of Energy’s Brookhaven National Laboratory, Stony Brook University, and the University of Nebraska describe one such approach that combines the excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor. The hybrid material exhibited enhanced light-harvesting properties through the absorption of light by the quantum dots and their energy transfer to tin disulfide, both in laboratory tests and when incorporated into electronic devices. The research paves the way for using these materials in optoelectronic applications such as energy-harvesting photovoltaics, light sensors, and light emitting diodes (LEDs).
