Silicone Wristbands And Its Five W"s It is not uncommon to wait until last minute to throw together a Halloween costume. Alternatively of dealing with a crowded store and having to pay as well considerably for a generic costume, generate your personal Halloween costume with products that you previously very own. Beneath are five distinct costume concepts for teen girls that can be customized to the person"s taste. If you own an organization you might want to give away these custom silicone wristbands because this helps more individuals to see your enterprise identify. The a lot more men and women that see your firm title, the much more customers you"re going to get. That signifies you want to be certain you are acquiring a bunch of these bands and giving them out to your workers. After they all have a single then give them out at trade exhibits or to some of your huge clientele. The much more folks who wear one of these silicone bands, the more individuals will potentially see it. Lego. This is obviously a classic. Lego is a massive youth presence for numerous years now, and its recognition is basically growing more powerful. For your celebration, you can produce an remarkable Lego centerpiece and share Lego loot bags containing things like Lego erasers and silicone wristbands. If you have an previous prom dress or other formal dress gathering dust in your closet, you"ve received the best beginnings of a low-cost and easy Halloween prom queen costume. Find a satin sash and create the words "Homecoming Queen" or "Prom Queen" on it in material paint. Get a cheap costume tiara or make a tiara yourself making use of hefty gauge wire and beads. With wristbands a popular vogue trend in recent years, several men and women appear for an area to get custom rubber bracelets. An Web search turns up thousands of World wide web web sites for acquiring rubber bracelets, so how is 1 to decide on the proper one particular? There are several aspects to take into account when choosing a supplier. Look for one that"s been in company for many years, an indicator of stability in the industry. Any individual can begin a company, but not absolutely everyone can do the work proper. You can put with each other a "make your personal ornaments" craft class and charge a modest fee to every attendee plus make a small additional on supplies. Get the supplies in bulk in the off-season and routine yours near the Thanksgiving timeframe. You can also offer Christian-themed ornaments, nativity scenes, decorations, and so forth. for sale as effectively. There are many vendors in the nearby markets who deal in custom stamp.

In situation there is a festival and you require gifts in bulk, you can area an order for customized rubber stamps and avail bulk discount on it.

WASHINGTON - Chinese scientists have developed an cost-effective hybrid power generator that generates electricity both in sunny conditions and by collecting the mechanical energy of falling raindrops in rainy days.

In a study published in the latest edition of ACS Nano journal, scientists from China"s Soochow University introduced their new invention -- a device that combines an existing solar cell with a triboelectric nano-generator (TENG).

The solar cell, as its name suggests, collects solar energy as the source for electricity, while the TENG harvests the mechanical energy generated from the motion of raindrops and transforms it into electricity.

According to Wen Zhen, the paper"s first author, the biggest breakthrough in this research is that the device is an integrated generator comprising a solar cell and a TENG, and that the two parts share a mutual electrode, which transfers energy from the TENG to the cell.

"The mutual electrode for both the TENG and the solar cell simplifies the structure," Wen told Xinhua.

"Compared to previous work, the simple design of the mutual electrode reduces the number of functional layers, which greatly improves the output efficiency," he was quoted as saying by phys.org, a web portal that compiles science and technology news.

In addition to making the device more compact, the innovative design also brings advantages to both the solar cell and the TENG. For example, the TENG actually acts as a waterproof barrier to protect the solar cell so that water will not penetrate through the silicon.

Furthermore, the textured surface of the electrode, known as PEDOT:PSS, avoids unwanted reflection of light, thus enhancing light collection. Also, by equipping the device with another textured polymer called PDMS, the scientists created a greater contact area between the TENG and falling raindrops and improved the performance of the nano-generator.

Since the polymers are transparent, the solar cell could still generate energy from sunlight, as well as from falling raindrops.

This simple design demonstrates a new concept in energy harvesting during various weather conditions, Wen said.

Although the solar cell and the TENG make the device dual-functional, Wen said the two parts cannot function simultaneously "due to the design of the mutual electrode," but he considered this only a minor drawback.

He said in case of a sunshower -- where sunshine and raindrops appear at the same time -- people will have to abandon one of the hybrid generator"s two functions. "But I don"t think that is often the case," he added.
