Scientists develop 3D conic device to increase solar-theflexible wristbandrmal conversion

Summer Festival Preview I like to visit with my friends and I like to cook and when I put these two things together it is called a party. I have never thought of myself as an event planner but I do love to plan parties at my home and I have become quite efficient at it. Trust me I am no Martha Stewart and lets face it most of us are not. The important thing is do what you love. If you want a theme party do it, and if you want an intimate dinner then have at it. You are in the driver"s seat. The important piece is to plan. Never be afraid of too much planning but do not let the planning take away the fun. Stay flexible. Head to the beach. Many families say good-bye to summer by spending Labor Day weekend at Virginia Beach. The Verizon Wireless American festival wristbands will entertain people of all ages with oceanfront concerts, food and fun. "It was a really big thing for me," says Brad Warner, director of the punk documentary film "Cleveland"s Screaming." His documentary offers a glimpse into the fire that burned inside members of the Cleveland and Akron punk scenes.
Besides choosing whether your event will be in-person or virtual, you should also identify the length of the event. Will it be just for a few hours, an all-day event or held over several days. What will you cover, and how you"ll present it? Will you host invited speakers? Will it be a Question and Answers event wristbands? Or will the event be a live training seminar or workshop? During this phase, you should decide on the number of participants that you will be comfortable hosting. Are you visualizing a small group of less than 20 people? Or do you see yourself talking to a larger group perhaps in the hundreds? It Might Get Loud: PG for mild thematic elements, brief language and smoking. 97 mins. Guitar soloists and trendsetters Jimmy Page The Edge and Jack White sit down together to discuss their style how they crafted it to teach and to sport wristbands talk all things guitar. Movement (especially movement of the spinal joints) creates an important type of neurological communication - proprioception. It fires up communication to the brain, allowing the brain itself to function at higher levels of performance. One other thing: the early bird gets the worm. The WMS has a history of selling out, and prices go up considerably on festival day, anyhow-so be sure to get your wristbands early. Currently, festival wristbands are available for only $20, with VIP passes available for $75. The wristbands are good for any venue, all day. Even without knowing the specific lineup of locals, $20 to see all of them means you"ll definitely get your money"s worth.

BEIJING -- Chinese scientists have developed a new device of 3D hollow-cone structure that can greatly increase the solar-thermal conversion efficiency.

The device, named artificial transpiration by Zhu Jia and his team from Nanjing University, is inspired by the transpiration processes of trees, according to an article published online recently by National Science Review, a English journal affiliated with Chinese Academy of Sciences.

It has a special 1D water path within it, which can reduce the energy loss in conduction, the article said.

The cone structure, based on graphene oxide film, can collect more sunlight throughout the day compared with a flat device, as about 10 percent to 50 percent of sunlight is diffusive. Thus it performs even better in the real world than in the laboratory, it said.

As a result, the device can enhance the solar-thermal conversion rate to 85 percent, much higher than the 40 percent of common devices, it said.

Solar power has been refrained from being applied in many sectors due to its low conversion rate caused by losses in radiation, convection and conduction. The device will open new possibilities to utilize solar energy.

Zhu"s team first applied this structure to solar waste-water treatment, and the test showed that it could not only retrieve clean water but also recycle heavy metals such as copper and cadmium.

In the future, the structure can be further optimized to have a longer life time and recycle more heavy metals, the article said.
