You Can Actually Find Out About Home Based Businesses Online ...

Not every person is cut out to own their own home-based business, but that doesn?t suggest you should not give it a shot. This is especially true today, when at an insignificant cost you can put in place any of a number of home-based businesses with a computer. It just takes a low cost, high-speed Internet access, and the motivation to spend a bit of time doing the research. In contrast to a local brick-and-mortar business, which is costly to set up, and is confined to local customers, your computer business can be world wide. Anytime you are discovering a marketing or advertising method for the first time, it is almost always helpful to withhold judgment about it. We suppose many people are close-minded in matters like this because maybe they are arrogant or simply go through life like that. Most likely you are familiar with interactive agency or at least aspects of it. On the other hand, there are a lot of people who are led too easily and tend to believe without due diligence.

If you are impatient and fail to do your due diligence, then you are obviously taking certain risks with your time and possibly money. Maybe it is just survival of the fittest and those who succeed are the ones who use common sense in business along with other qualities. There are many marketers who deal with beginners and these businesses are honest and legitimate, but it is the small percentage who are not honest that cause perception problems. We really pretty much do not care who it is, if something is new to you then you have to preform some research to get another side of the story. Maybe you have already had experiences in which smart homework saved you some money. Everyone in the world with internet access is a potential consumer.

There are many opportunities you might be thinking about trying, if you are seriously interested in giving an online business a shot. You can actually begin on the Internet without having to be a computer geek, but knowing about working with a computer does help. Often, making money online has nothing to do with your technical skills, but with how much you know about the things you enjoy doing. One example of a web business for people who are very good at writing would be doing copy writing. As they say, content is king, so people with writing skills can certainly become freelance writers for those who aren?t good at writing. The secret, if you could provide a specific skill, like content in our writer?s example, is to track down those individuals who have a need for it and sell it to them. Create a collection of your work, do some marketing, and, hey presto! you have a business.

Online auction websites are another avenue from which many people are making big money. Maybe you have one or more products that you can actually market internet, or you could source some from wholesalers and then profit by adding a mark-up. The hard work of obtaining shoppers to see your offers is carried out by the online auction sites, like eBay. What?s required from you is to fix the price for your product, add it to the sales listings and wait for shoppers to order it. When your product is sold, you get sent the funds and then you have the product shipped to the customer.

Study improves understanding of surface molecules in controlling size of gold nanoparticles

Study improves understanding of surface molecules in controlling size of gold nanoparticles

Monday, June 18, 2012

North Carolina State University researchers have shown that the "bulkiness" of molecules commonly used in the creation of gold nanoparticles actually dictates the size of the nanoparticles ? with larger so-called ligands resulting in smaller nanoparticles. The research team also found that each type of ligand produces nanoparticles in a particular array of discrete sizes.

"This work advances our understanding of nanoparticle formation, and gives us a new tool for controlling the size and characteristics of gold nanoparticles," says Dr. Joseph Tracy, an assistant professor of materials science and engineering at NC State and co-author of a paper describing the research. Gold nanoparticles are used in industrial chemical processes, as well as medical and electronics applications.

When creating gold nanoparticles, scientists often use organic molecules called ligands to facilitate the process. The ligands effectively bring gold atoms together in a solution to create the nanoparticles. In the process, ligands essentially line up side by side and surround the nanoparticles in all three dimensions.

The researchers wanted to see whether the bulkiness of the ligands affected nanoparticle size, and opted to assess three types of thiol ligands ? a family of ligands commonly used to synthesize gold nanoparticles. Specifically, the molecules bound to the gold nanoparticles are linear hexanethiolate (-SC6), cyclohexanethiolate (-SCy) and 1-adamantanethiolate (-SAd). Each of these ligands has a bulkier configuration than the last.

For example, picture each ligand as a slice of pie, with a gold atom attached to the pointed end. -SC6 looks like a very narrow slice of pie. -SCy is slightly larger, and -SAd is the largest of the three ? with the "crust" end of the pie wedge far wider than the pointed end.

The researchers found that the bulkiness of the ligands determined the size of the nanoparticles. Because fewer -SAd and -SCy ligands can line up next to each other in three dimensions, fewer gold atoms are brought together in the core. Therefore, the nanoparticles are smaller. -SC6, the least bulky of the thiolates, can create the largest nanoparticles.

"While we've shown that this is an effective means of controlling size in gold nanoparticles, we think it may have implications for other materials as well," says Peter Krommenhoek, a Ph.D. student at NC State and lead author of the paper. "That's something we're exploring."

But the researchers made another interesting finding as well.

When particularly small nanoparticles form, they tend to form at very specific sizes, called discrete sizes. For instance, some types of nanoparticles may consist of 25 or 28 atoms ? but never 26 or 27 atoms.

In this study, the researchers found that the bulkiness of the ligands also changed the discrete sizes of the nanoparticles. "This is interesting, in part, because each discrete size represents a different number of gold atoms and ligands," Tracy says, "which could influence the nanoparticle's chemical behavior. That question has yet to be addressed."

The paper, "Bulky Adamantanethiolate and Cyclohexanethiolate Ligands Favor Smaller Gold Nanoparticles with Altered Discrete Sizes," is published online in ACS Nano.

Exhausted Suu Kyi falls ill during news conference

BERN, Switzerland (AP) ? A rock star welcome greeted Aung San Suu Kyi as she embarked on her first trip to Europe in 24 years. But after a whirlwind of standing ovations, speeches and receptions, it all became too much, and she fell ill Thursday during a news conference in Switzerland.

The 66-year-old Nobel Peace Prize laureate became sick shortly after saying how exhausted she was after her long trip from Asia to Europe, which brought her to Geneva late Wednesday night. It was not known how her apparent exhaustion would affect the rest of a tightly-packed schedule, which includes delivering her Nobel Peace Prize acceptance speech in Oslo on Saturday, 21 years after winning the award.

Suu Kyi looked pale as she took questions Thursday evening alongside Foreign Minister Didier Burkhalter in the Swiss capital of Bern. After a few minutes, she pressed a finger to her lips and motioned to an aide who rushed to her side with a bag. She then bent over and threw up before being escorted out of the room by officials.

A spokesman for the Swiss Foreign Ministry said Suu Kyi recovered enough to briefly attend a reception with government officials later but then retired to her room.

"She's just a bit tired," spokesman Jean-Marc Crevoisier told The Associated Press. "I would be, too, after the long day she's had."

Earlier, the woman who has become an icon for the democracy movement had blamed age and lack of travel for her tiredness.

"Having stayed in one place for so long, I found the plane journey out to the West extremely exhausting and a little bit disorienting because I couldn't adjust to the new time as quickly as I might have 24 years ago," Suu Kyi told reporters. "It may, of course, have something to do with age. It may have to do with lack of practice."

The United Nations in Geneva was the first stop of her two-week European tour. Her appearance at a U.N. labor conference ? an unlikely venue for glitz and glamor ? had starry-eyed functionaries reaching for their camera phones to snap a picture as Suu Kyi smiled and shook hands with well-wishers.

"You fill this room with the light of your spirit," said Juan Somavia, the ILO's director general.

The evening before, as Suu Kyi arrived at her hotel shortly before midnight after a long flight, spontaneous applause erupted in the lobby as the staff recognized their special guest.

Suu Kyi, who endured 15 years of house arrest and once feared permanent exile if she ever left Myanmar, has become the country's most electric ambassador.

During this trip, Suu Kyi is expected to lay out how her country has changed and what still needs to be done before it can be called a proper democracy. She also had planned to address both houses of Britain's parliament, receive an honorary doctorate from Oxford, attend a U2 concert in Dublin, and deliver in Oslo the acceptance speech for the Nobel Peace Prize that she won in 1991.

At that time, Suu Kyi was detained by the military after leading a pro-democracy party to victory in Myanmar's 1990 election. The prize was picked up instead by her 18-year-old son Alexander.

"I've been so exhausted preparing for the trip that I've had no time to think about how I'm going to feel about Oslo, but perhaps this evening I'll sit back and think about it," Suu Kyi told reporters after her speech to the U.N. labor office.

The Geneva-based agency has long campaigned against forced labor in Myanmar, earning it a first stop on Suu Kyi's much-anticipated tour.

The leader of Myanmar's opposition National League for Democracy stepped carefully around sensitive subjects such as the ethnic unrest brewing in her country's western Rakhine province.

She said foreign investment must help ? not hurt ? Myanmar's goal of moving toward full democracy, referring to the exploitation of Myanmar's oil and gas riches, the subject of recent deals between the government and China. Western companies, too, have been eager to invest in the Southeast Asian nation as the sanctions it faced under military rule are gradually lifted.

"Any new investment that comes in because of the lifting or suspension of sanctions should add to the democratic process rather than subtract from it," Suu Kyi said.

Asked about the abuses committed by the junta during its decades-long rule, Suu Kyi struck a conciliatory note, citing fellow Nobel winner Archbishop Desmond Tutu.

"At this moment, what I want most of all is reconciliation and not retribution," she said.

She took the same high road when it came to her own suffering at the hands of the military, which barred her British husband from visiting her in Myanmar as he was dying from cancer.

"In some ways I don't think they really did anything to me," she said. "I do not think I have anything to forgive them for."
