which can be metals semiconductors dielectrics and even superconductors. This material is the newest in a growing family of two-dimensional crystals says Arend van der Zande a research fellow at the Columbia Energy Frontier Research center and one of the paper's three lead authors.

Similar to the chloroplasts in green plants that carry out photosynthesis our artificial photosynthetic system is composed of two semiconductor light absorbers an interfacial layer for charge transport

The paper is titled A Fully Integrated Nanosystem of Semiconductor Nanowires for Direct Solar Water Splitting.

Yang and his colleagues also use A z-scheme in their system only they deploy two Earth abundant and stable semiconductors--silicon

The majority charge carriers from both semiconductors recombine at the ohmic contact completing the relay of the Z-scheme similar to that of natural photosynthesis. Under simulated sunlight this integrated nanowire-based artificial photosynthesis system

The CNC substrates on which the solar cells are fabricated are optically transparent enabling light to pass through them before being absorbed by a very thin layer of an organic semiconductor.

another new paper from Rice on a hybrid graphene-hexagonal boron nitride shows the need for a 2-D semiconductor to complement the material's conducting

Semiconductors are the basic element of modern electronics that direct and control how electrons move through a circuit.

But when a disturbance deepens a band gap the semiconductor is less stable. When chaos reigns in the form of multiple point defects

A new study shows that light-emitting diodes (LEDS) can give greenhouse growers other lighting options that produce favorable results.

Light-emitting diodes (LEDS) can offer growers benefits such as higher energy efficiencies and a longer operating life. To determine whether the use of narrow-spectra high-intensity LEDS is can be a practicable supplemental lighting source for greenhouse grown annual bedding plant seedlings researchers Wesley Randall

and Roberto Lopez from Purdue University designed a series of lighting experiments on plugs of Antirrhinum Catharanthus Celosia Impatiens Pelargonium Petunia Tagetes Salvia and Viola.

blue LEDS compared with seedlings grown under HPS lamps. The quality index was significantly higher for Petunia Salvia and Viola under 85:15 70:30 and 100:0 red:

blue LEDS than under HPS lamps respectively. Overall the results indicate that seedling quality for the majority of the species tested under supplemental light LEDS providing both red

and blue light was similar or higher than those grown under high-pressure sodium lamps. Our results indicate that providing supplemental lighting from LEDS

or high-pressure sodium lamps has a positive influence on seedling root dry mass height and stem caliper leading to high-quality bedding plant seedlings

although blue LEDS have a higher electrical conversion efficiency compared with red LEDS blue light is a higher energy light

#Light-emitting diode treatments outperform traditional lighting methods for hydroponically grown tomato plantsin Canada where outdoor growing seasons are limited sales from greenhouse fruit

whether light-emitting diodes (LEDS) could reduce lighting costs in greenhouses. LEDS can be selected to target the wavelengths used by plants enabling growers to customize the light produced to enable maximum plant production

and limit wavelengths that do not significantly impact plant growth they explained. The scientists subjected hydroponically grown tomato plants to three light intensities at three red-to-blue ratio levels.

Secondary lighting treatments used for comparison included 100%high-pressure sodium (HPS) 100%red LED light supplied from above the plant 100%red LED light supplied below the plant a 50%:50%LED:

(341 fruit) 19:1 high (315 fruit) and 100%LED (310 fruit. Overall the highest producing LED treatments consistently outperformed the high-pressure sodium treatment alone the authors said.

The highest marketable fruit production resulted from the 50%:50%LED: HPS treatment. The authors said that the 5: 1 high treatment performed well in every category.

They concluded that LEDS are a promising mechanism to enhance greenhouse artificial lighting systems. Story Source:

diselenide--a highly sought semiconductor that is similar to graphene but has better properties for making certain electronic devices like switchable transistors and light-emitting diodes.

The method for making two-dimensional molybdenum diselenide uses a technique known as chemical vapor deposition (CVD)

because CVD is used widely by the semiconductor and materials industries to make thin films of silicon carbon fibers and other materials.

In solid-state physics electron mobility refers to how quickly electrons pass through a metal or semiconductor in the presence of an electric field.

The research was supported by the Army Research Office the Semiconductor Research Corporation's FAME Center the Office of Naval Research and Singapore's MOE Academic Research Fund.

They found it to be much better than nanofluids that contain higher amounts of oxide nitride or carbide ceramics metals semiconductors carbon nanotubes and other composite materials.

it's still the computers, automotive, telecommunications and semiconductor industries that lead industry in terms of sheer number of patents.

overall patent volume for the automotive industry actually surpassed the telecommunications and semiconductors industries in 2010.

it was powered alternatively vehicles that led the way, posting a 21 percent increase from 2009.
