Herramientas de Monitoreo de Social Media ~ e-ngenium blog Down to the wire: Inexpensive technique for making high quality nanowire solar cells Solar or photovoltaic cells represent one of the best possible technologies for providing an absolutely clean and virtually inexhaustible source of energy to power our civilization. However, for this dream to be realized, solar cells need to be made from inexpensive elements using low-cost, less energy-intensive processing chemistry, and they need to efficiently and cost-competitively convert sunlight into electricity. A team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has now demonstrated two out of three of these requirements with a promising start on the third. Peidong Yang, a chemist with Berkeley Lab's Materials Sciences Division, led the development of a solution-based technique for fabricating core/shell nanowire solar cells using the semiconductors cadmium sulfide for the core and copper sulfide for the shell. This research was supported by the DOE Office of Science.
Six Keys to Being Excellent at Anything - Tony Schwartz by Tony Schwartz | 2:21 PM August 24, 2010 I’ve been playing tennis for nearly five decades. I love the game and I hit the ball well, but I’m far from the player I wish I were. I’ve been thinking about this a lot the past couple of weeks, because I’ve taken the opportunity, for the first time in many years, to play tennis nearly every day. My game has gotten progressively stronger. And almost certainly could be, even though I’m 58 years old. During the past year, I’ve read no fewer than five books — and a raft of scientific research — which powerfully challenge that assumption (see below for a list). We’ve found, in our work with executives at dozens of organizations, that it’s possible to build any given skill or capacity in the same systematic way we do a muscle: push past your comfort zone, and then rest. Like everyone who studies performance, I’m indebted to the extraordinary Anders Ericsson, arguably the world’s leading researcher into high performance. Pursue what you love.

30 Financial Moves Before 30– Ideas Worth Trying January 13, 2011, 6:00 amby:MD Category:Miscellaneous I started reading the Art of Non-Conformity the other day and the idea of the life list/bucket list got me thinking again. I started thinking about my bucket list for what I want to accomplish before I turn 30 (in 7 years). Then I started to get more specific. Since every financial bucket list is unique to your own situation, I decided to outline 30 financial moves that might be of interest to your unique financial situation before you turn 30. 1. Keep a buffer in a savings account because you never know when a rainy day will hit you out of nowhere. 2. You can debate good debt vs bad debt, but at the end of the day you should try to kill off your credit card debt before you turn 30. 3. The sooner you start planning for your retirement, the sooner you have compound interest working on your side. 4. You may not try to do this deliberately but it’s bound to happen. 5. When you make a major mistake with your money, learn from it. 6. 7. 8.

How to Copyright? | Get Free Copyright Protection Online | Myows® 13 Business Books That Will Blow Your Mind Having never taken a business class in college I find that I read and listen to a lot of business books to round out my education. The books usually aren't "How to Manage Your Cash Flow" but rather get me to rethink the way I run my business, which--despite no business classes or diploma--continues to be in business 13 plus years after I started it. In that time, here are 13 of the books that had the biggest impact on how I run my business (in no particular order): Drive: The Surprising Truth About What Motivates Us by Daniel Pink: If you supervise anyone in your business, this book is a must read. It shows that what science knows about motivation, business isn't putting into practice. The Knack: How Street-Smart Entrepreneurs Learn to Handle Whatever Comes Up by Norm Brodsky and Bo Burlingham: I wanted to have at least one book that was dedicated to small business and the entrepreneurial spirit.
