Wind Turbines and Wear and Tear

Wind turbines in a field

A modern wind turbine has more than 8,000 component parts that must withstand the wear and tear of wind stresses. DOE researchers and stakeholders have been working hard to predict and eliminate wind stress related barriers and extend the lifespan of wind turbines.  Working on a paper on this subject? OSTI can save you wear and tear by providing web tools that eliminate the need to search through database after database to find the research you need.  For example, if you use DOE’s Science Accelerator, you could search through 11 DOE databases, and in about 10 seconds or less, retrieve hundreds of documents about the use of simulations to understand wind turbine shear stress.You could learn about...

OSTI and Its Mission Highlighted in Secretary Chu’s Policy Statement on Scientific Integrity

The Office of Scientific and Technical Information (OSTI) plays an integral role in ensuring transparency and access to the results of the Department of Energy’s scientific efforts – and such transparency and access help assure DOE’s scientific integrity, according to a policy statement recently issued by Secretary of Energy Steven Chu. 

“Science and technology are the foundation of all Department of Energy activities…,” the Secretarial Policy Statement on Scientific Integrity opens. “The Department’s mission relies on objective, reliable, accurate, and accessible scientific and technical information.”  And OSTI addresses the agency’s responsibilities to collect, preserve and disseminate scientific and technical information emanating from the Department’s research and development activities.

“In December 2010,” Secretary Chu wrote in a May 11 memo to DOE employees, “the Office of Science and Technology Policy at the White House issued a memorandum asking all agencies to establish a scientific integrity policy.  In response to this call, I recently signed the Secretarial Policy Statement on Scientific Integrity for the Department of Energy applicable to all DOE Federal employees.  This policy builds on the Department’s existing policies and best practices to support a culture of scientific integrity.”

“DOE will facilitate the free flow of scientific and technological information,” the policy statement provides, “consistent with standards for treatment of classified, sensitive, private, and proprietary information.  Transparency and accessibility of scientific and technological information support the continued advancement of a sound science and technology base to help guide and inform the nation’s critical public policy decisions; advance the national, economic and energy security of the U.S.; facilitate the...

Happy Mathematics Awareness Month

MATH

 

“Pure mathematics is, in its way, the poetry of logical ideas.”

  ~Albert Einstein

As you prepare your taxes, keep in mind that April is  Mathematics Awareness Month.  This year’s theme is, “Mathematics, Statistics and the Data Deluge”.

Mathematics is used throughout the world as an essential tool in many fields, including natural science, engineering, medicine and the social sciences. Large amounts of data are collected every day, and scientific data comes in massive amounts from supercomputers, sensor networks, astronomical instruments and other devices.  These data need to be sorted out and understood in order to be useful.

The White House recently released its Big Data Research and Development Initiative, and OSTI, was recognized as playing a "key role " in shaping the policies and technical implementation of the practice of data citation. Data citation enables efficient reuse and verification of data

OSTI not only ensures that DOE research is tracked, but that a scholarly structure is in place to reward data producers.  OSTI recently implemented a Data Identification Service across the DOE complex through which Digital Object Identifiers (DOIs) are assigned...

Celebrate National Engineers’ Week 2012 – February 19-25, 2012

George Washington

 

National Engineers’ Week was started in 1951 by the National Society of Professional Engineers.  The celebration is held in conjunction with President George Washington's Birthday; our first President is considered by many engineers to be the nation's first engineer because of his survey work.

Engineers use imagination and analytical skills to invent, design, improve and build things and turn ideas into reality, apply basic research and dream up creative and practical solutions.  Engineering has made numerous contributions to modern life, and has made it more comfortable, safe and prosperous.  Engineers change the world.

The engineering field is as varied as engineers themselves. Engineers design and build superstructures and delicate medical instruments.  They explore for energy and better and more efficient ways to deliver it, they design environmental controls for buildings and drive innovation in various fields of energy such as wind, fuel cell technology, solar energy, geothermal energy, petroleum, gas, nuclear engineering, alternative energy, energy efficiency, fusion, hydrogen and superconductor technologies.

At DOE and its National Laboratories engineers support the discovery and design of new...

National Nuclear Science Week – January 23-27, 2012

Nuclear science comprises many fields. From astrophysics to radioisotopes, nuclear science starts with the atom. The atom, and its fundamental building blocks of protons and neutrons, is the bundle of radioactive energy that makes so much possible.

National Nuclear Science Week is designed to recognize the contributions of nuclear science and those who work in it every day.   Did you know that nuclear science is used in archeology, food safety and nuclear medicine?  Or to help industry with such things as locating cracks in steel, getting rid of dust from film, or measuring the amount of air whipped into ice cream?  And that nuclear power provides 20% of the electricity in the United States?

The Department of Energy’s Office of Nuclear Energy’s mission is to advance nuclear power as a resource capable of meeting the nation's energy, environmental and national security needs by resolving technical, cost, safety, proliferation resistance and security barriers through research, development and demonstration. DOE is also strongly committed to supporting graduate education,competitive research and advanced scientific tools in the areas of nuclear physics, nuclearchemistry and nuclear engineering.

Its Nuclear Energy University Programs (NEUP) fund projects with American universities to facilitate collaborations that lead to breakthroughs in nuclear energy technologies, specifically on breakthroughs that align with the mission of the Office of Nuclear Energy. The broad...

Snowflake Science

Snowflake

 

With winter just around the corner, can snow be far behind?

We’ve all heard that no two snowflakes are alike, but what do we really know about them?

Snowflakes always have six sides.   Their form and shape depends on temperature and moisture.   Snowflake shapes fall into six main categories:  plate (flat), column, stars, dendrite (lacy), needle and capped column. When it is extremely cold, snow becomes fine and powdery and the snowflakes’ design becomes simpler, usually needle or rod shaped. When the temperature is close to freezing point, snowflakes become much larger and more complex in design.

Snow crystals form in clouds when the temperature is below freezing and are created by water droplets freezing on small ice particles. As an ice crystal drops through the cloud it bumps and knocks others and becomes a snowflake. This process of bumping others, along with melting and re-freezing aids the creation of their complex design. The air that the snowflake drops through has to be under freezing or the snowflake will simply melt and turn into rain.

Physicists working on the National Spherical Torus Experiment (NSTX) at the Princeton Plasma Physics Laboratoryare working to solve one of the grand challenges of magnetic fusion research:  reducing the effect that plasma has on the walls of the tokamak.  By using a "snowflake" diverter, a novel magnetic diverter named for its shape, scientists...

“The New Einsteins Will Be Scientists Who Share.”

Albert Einstein

 

In an October 29, 2011 Wall Street Journal article, “The New Einsteins Will Be Scientists Who Share,”  Dr. Michael Nielsen stated that networked science has the potential to speed up dramatically the rate of discovery across all of science, and that we may well see the day-to-day process of scientific research change more fundamentally over the next few decades than over the past three centuries. He also noted that there are major obstacles to achieving this goal, including the lack of a systematic effort by scientists to adopt new tools of discovery or to share data – because they are busy, they may believe it’s a diversion from their “real” work or because they may not be familiar with the means to do so easily.

OSTI knows that the public and members of the scientific community may not be familiar with the multitude of different science databases.  OSTI addresses and solves these considerable challenges by providing vehicles for obtaining targeted, precise information quickly and easily.  We believe that shared knowledge is the enabler of scientific progress, and that accelerating the sharing of knowledge will accelerate discovery.  To these ends, OSTI uses and extends modern communication technologies.  Our databases are the largest national sources of energy and science R&D information in the world. 

OSTI resources include:
