2015 – A Good Year for Spintronics Research

Department of Energy (DOE) researchers and their collaborators continued to make significant progress throughout 2015 in the emerging field of spintronics, also known as magnetic electronics.  Spintronics could change conventional electronics by using the spin of electrons to store information in solid state devices rather than, or in addition to, the transport of the electrical charge of electrons.  This new technology addresses many of the challenges of conventional electronics because it allows for transfer of information from one place to another using much less energy, essentially generating no heat, and requiring little space.  The field of spintronics is rapidly advancing and opportunities at the frontiers of spintronics are immense.

Amazing Aerogels

Aerogels are some of the most fascinating materials on the planet. They were discovered in the 1930s by Stanford University’s Samuel Kistler who proved that he could successfully replace a gel’s liquid with a gas by drying it, thereby creating a substance that was structurally a gel, but without liquid. Since their invention aerogels have primarily been made of silica but can be made of a growing variety of substances including transition metal oxides, organic polymers, biological polymers, semiconductor nanostructures, graphene, carbon, carbon nanotubes and metals as well as aerogel composite materials and the list is growing.

Enjoy the benefits of LED lighting

Every day we are bombarded with advertisements in every form and format telling us that our lives will be improved if we buy a particular product because it will save us money, reduce our work effort, save us energy, or benefit the environment. We are justifiably skeptical because we know from experience that if something sounds too good to be true, usually it is. Light-emitting diode (LED) lighting is one of the exceptions. LEDs benefits are so powerful that they seem too good to be true; however, they actually do save us money, reduce our work effort, save us energy and benefit our environment.

Light-emitting diode (LED) lighting is a type of solid-state lighting that uses a semiconductor to convert electricity to light. LED lighting products are beginning to appear in a wide variety of home, business, and industrial products such as holiday lighting, replacement bulbs for incandescent lamps, street lighting, outdoor area lighting and indoor ambient lighting.

The Reverend Thomas Bayes

Thomas Bayes

During the 1700’s, the Reverend Thomas Bayes was a nonconformist minister at the Mount Sion Chapel in Tunbridge Wells, UK, about 40 miles southeast of central London.  Having studied both theology and logic at the University of Edinburgh, he was also a mathematician and developed a strong interest in probability late in life. He was known to have published only one book on theology and one book on mathematics in his lifetime. A third manuscript he never published about the probability of cause made him famous. After his death, a good friend Richard Price recognized the importance of the paper and, after extensive editing, submitted it for publication. More than 20 years later, the great French mathematician, Pierre-Simon Laplace devised the formula for Bayes’ probability of causes and acknowledged Bayes as the discoverer of what we now know as Bayesian inference.

OSTIBlog has a new look

by Tim Byrne 05 Jul, 2013 in Science Communications

The redesign of OSTIblog makes it easier to find and view blog articles.  The OSTIblog home screen now displays the title, image and opening paragraph for the last five articles.  Earlier articles can be paged through, again viewing five per page. 

The new menu bar has tabs for Topics, Authors, and Archive. The Topics tab allows users to browse OSTIblog articles assigned to one of four topic areas:  Personal Perspectives, Products and Content, Science Communications, and Technology.  There is also an option to browse by the name of an OSTI database, search tool or other product.  The last choice under the Topics tab is to browse OSTIblog articles by subject tags
