New Innovative Substance to be used in Solar Cells and Flexible Electronics

~ Michael D. Turashoff ~ Leave a comment

  Physicists at the University of Kansas have created an innovative substance from two different atomic sheets that interlock like Lego toy bricks. The researchers said the new material, made of a layer of graphene and a layer of tungsten disulfide, could be used in solar cells and flexible electronics.   Hsin-Ying Chiu, assistant professor … Continue reading New Innovative Substance to be used in Solar Cells and Flexible Electronics

Webcast About Great Battery Experiments from Iron Science Teacher

~ Michael D. Turashoff ~ Leave a comment

In a parody of the cult Japanese TV program, “Iron Chef,” here is an excellent video where a live audience at the Exploratorium, in San Francisco, cheer on competitors in a fun science cook-off, where teachers compete for the sought-after title, “Iron Science Teacher.”   The Exploratorium’s Iron Science Teacher competition showcases science teachers as … Continue reading Webcast About Great Battery Experiments from Iron Science Teacher

Car Powered by its Body Panels

~ Michael D. Turashoff ~ Leave a comment

  Researchers have developed lightweight supercapacitors that, when combined with regular batteries, dramatically boost the power of an electric car.   The supercapacitors, a “sandwich” of electrolyte between two all-carbon electrodes, were made into a thin and extremely strong film with a high power density.   The film can be embedded in a car’s body … Continue reading Car Powered by its Body Panels

Major Increase in Production of Hydropower Expected this Decade

~ Michael D. Turashoff ~ Leave a comment

  A major increase in the construction of hydropower dams is underway, mainly in developing countries and emerging economies. Since this trend is expected to double global electricity production from hydropower, it could reduce the number of our last remaining large free-flowing rivers by about 20 percent and pose a serious threat to freshwater biodiversity. … Continue reading Major Increase in Production of Hydropower Expected this Decade

The Weight of Traffic and Pedestrians can Generate Electricity

~ Michael D. Turashoff ~ Leave a comment

  Mexican entrepreneurs have developed a system capable of using the flow of vehicles to generate electric energy. This development has the potential to produce sufficient electricity to supply power to a household through a device that “catches” the force of the moving cars.   “This is a technology that provides sustained energy and could … Continue reading The Weight of Traffic and Pedestrians can Generate Electricity

Eco-friendly New Battery Made of Pine Resin and Seeds

~ Michael D. Turashoff ~ 1 Comment

  Even though today’s lithium batteries are efficient, they cause a range of resource and environmental problems. Uppsala researchers have now come up with a very interesting alternative using materials from alfalfa (lucerne seed) and pine resin, along with a clever recycling strategy. Their study will be presented soon in the scientific journal ChemSusChem.   … Continue reading Eco-friendly New Battery Made of Pine Resin and Seeds

Researchers Develop Technology to Estimate Range of Electric Vehicles

~ Michael D. Turashoff ~ Leave a comment

  North Carolina State University researchers have developed new software that estimates how much farther an electric vehicle can drive before needing to recharge.   The new technology requires drivers to enter their destination, then the software automatically compiles the data on a host of variables to predict the energy use for the vehicle.   … Continue reading Researchers Develop Technology to Estimate Range of Electric Vehicles

World’s First Solar Cell that Stores its Own Power

~ Michael D. Turashoff ~ Leave a comment

    Is it a solar cell or a rechargeable battery? Both! The patent-pending device invented at The Ohio State University is the world’s first solar battery.   In the October 3, 2014 issue of the journal Nature Communications, the Ohio State researchers reported that they’ve succeeded in combining a battery and a solar cell … Continue reading World’s First Solar Cell that Stores its Own Power

What is a Square-Wave

~ Michael D. Turashoff ~ Leave a comment

  A square wave is a non-sinusoidal periodic waveform (which can be represented as an infinite summation of sinusoidal waves), in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration spent at minimum and maximum.   The transition between minimum to maximum is instantaneous for an … Continue reading What is a Square-Wave

What is a Sine Wave

~ Michael D. Turashoff ~ Leave a comment

  The sine wave or sinusoid is a mathematical curve that describes a smooth repetitive oscillation. It is named after the function sine, of which it is the graph. The sine wave occurs often in pure and applied mathematics, as well as physics, engineering, signal processing and many other fields.   The sine wave is … Continue reading What is a Sine Wave
