Cancer Nano 5-promisingnew #5 – New “Nanoparticle-Based” Sensor for Screening Cancer Drugs: Fast AND Accurate:

Traditional genomic, proteomic and other screening methods currently used to characterize drug mechanisms are time-consuming and require special equipment, but now researchers led by chemist Vincent Rotello at the University of Massachusetts Amherst offer a multi-channel sensor method using gold nanoparticles that can accurately profile various anti-cancer drugs and their mechanisms in minutes.

 NG camry%20CNG%20hybrid#4 – Rice University Research Fuels Hopes for Natural Gas Cars:

Cars that run on natural gas are touted as efficient and environmentally friendly, but getting enough gas onboard to make them practical is a hurdle. A new study led by researchers at Rice University promises to help. Rather than shoehorn bulky high-pressure tanks like those used in buses and trucks into light vehicles, the Department of Energy (DOE) encourages scientists to look at new materials that can store compressed natural gas (CNG) at low pressure and at room temperature.

Cage-like synthetic macromolecules called metal organic frameworks (MOFs) are among the candidates.


 Nano Wires Solar 140411102933#3 – Building a New ‘Nanowire’ for Solar Cells (Video):

Nanowires are structures whose thickness is in the order of a nanometer (10-9 meters) but their length can be considerably longer. At the cutting edge of science and engineering, nanowires are used in different ways depending on what they are made of, such as insulators and semiconductors in electronics and computer chips. Now, EPFL scientists have found a novel way to make nanowires from a light-absorbing lead-containing material called a perovskite, which is used in the new generation of solar cells. Their innovative yet simple method is published in Nano Letters (“Nanowires of Methylammonium Lead Iodide (CH3NH3PbI3) Prepared by Low Temperature Solution-Mediated Crystallization”).

No solar cell material ever has enjoyed such a rapid trajectory of improvements — nor the subsequent attention from researchers, industry, and media — as perovskite. This material, known for decades but whose ability to convert sunlight wasn’t appreciated until the past few years, has suddenly gained popularity with a velocity proportional to the flood of performance improvements coming out months and even weeks apart: from barely 3 percent conversion efficiency in 2009 to 10 percent in 2012, 16 percent in 2013, and as high as 19 percent according to recent conference reports. (A combination of c-Si cells and perovskite is thought to be able to achieve 32 percent efficiency.) That’s tantalizingly alongside the performance of mainstream conventional silicon-based PV, but with the potential for far simpler and cheaper processes and manufacturing.

 Nano Textiles id35064_2#2 – A ‘T-Shirt’ As a Power Source – New Energy Source Textiles:

Forget about Google Glass or the latest smart watch announcements – the future will belong to electronic textiles (e-textiles) that will allow the design and production of a new generation of garments with built-in unobtrusive sensors and a variety of electronic functions. Such e-textiles will have the revolutionary ability to sense, act, store, emit, and move – think biomedical monitoring functions or new man-machine interfaces – while ideally leveraging an existing low-cost textile manufacturing infrastructure.

All these wearable and potentially textile-embedded electronic gadgets will require power; and it wouldn’t make sense to have to plug your sleek flexible sleeve display into a bulky lithium-ion battery brick.


#1 – LG and Samsung Announce Quantum Dot TV: Market to Reach $9.6 Billion by 2023:

LG announced quantum dot TV; quantum dot market forecast December 16, 2014. Today LG announced it’ll showcase its quantum dot TV at the upcoming CES 2015. We also expect Samsung to show quantum dot TV. Quantum dot could improve Liquid Crystal Display (LCD) dramatically in terms of color gamut, color accuracy and reducing power consumption.

NanoMarkets believes that opportunities for commercial use of quantum dots (QDs) have changed dramatically in the past year, and this, our most recent report on QDs, identifies where the money will be made as the a result of these new trends and developments.

QDs have now exploded onto the commercial display market and are appearing in displays of all sizes, enabling LCDs with greater color gamut and lower power consumption. These QD-enhanced LCDs are already providing direct competition to OLED displays, raising the question of whether OLED displays will ever take off in the way that was once hoped.  At the same time NanoMarkets believes that ability of the QD makers to supply sufficient materials to support future growth is no longer an issue.

Happy Holidays and a Blessed New Year!
