Pearl Jewelry-Cosmetic Value of Pearls and Pearl Jewelry

Do you know that wearing a pearl strand necklace for a long time may help avoid faucitis (sore throat) and hyperthyroidism? This is because long term exposure to pearls can make the human body system "cool down", so wearing a pearl strand may also ease the temper during menopause. Besides, because of the smooth nature of nacre and the elements containing in pearls, the area on your neck, where expose to your pearl necklace, may become very smooth and soft.



In fact, people started to use pearls for medical and cosmetic use as early as 2000 years ago. Pearls contain plenty of chemicals including calcium, carbon, hydrogen, nitrogen, magnesium, manganese, aluminum, iron, tungsten, zinc, lead, silver, gold, lithium, iodine, zirconium, selenium, etc. The hydrolysate of pearl powder contains all kinds of aminophenol, which are essential for the balance of human body system. Taking pearl powder regularly may enhance metabolism, as a result your skin would become smooth, and it can slow down the aging process.



However, not every person is safe to take pearl powder because some people can't handle the cold nature of pearls, so most people virtually wear pearl jewelry or use pearl powder as a facial mask. By both ways, effective elements in pearl powder can filter through human pores, be absorbed by deep tissue, and result in cosmetic improvements. Pearl powder facial mask is more efficient though. Below are some tips to make a pearl powder facial mask.



1. Pearl powder + fruits + milk

Method: Blend apple, cucumber and pear together, add 2 spoons of milk, 2 spoons of water and 0.3g pearl powder, mix well, then apply on the face, wash away in 15 minutes.



2. Pearl powder + milk + honey + egg white

Method: mix 3 spoons of milk, 1.5 spoons of honey, one egg white and 0.3g pearl powder. Apply on the face, wash away in 15 minutes.



3. Pearl powder + olive oil

Method: mix one spoon of olive oil and 0.15g pearl powder, apply around eyes for 15 minutes and clean it.

photovoltaic cell-Photovoltaic (solar cell) Systems

Solar cells convert sunlight directly into electricity. Solar cells are often used to power calculators and watches. They are made of semiconducting materials similar to those used in computer chips. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. This process of converting light (photons) to electricity (voltage) is called the photovoltaic (PV) effect.

photovoltaic cell

Solar cells are typically combined into modules that hold about 40 cells; a number of these modules are mounted in PV arrays that can measure up to several meters on a side. These flat-plate PV arrays can be mounted at a fixed angle facing south, or they can be mounted on a tracking device that follows the sun, allowing them to capture the most sunlight over the course of a day. Several connected PV arrays can provide enough power for a household; for large electric utility or industrial applications, hundreds of arrays can be interconnected to form a single, large PV system.

Thin film solar cells use layers of semiconductor materials only a few micrometers thick. Thin film technology has made it possible for solar cells to now double as rooftop shingles, roof tiles, building facades, or the glazing for skylights or atria. The solar cell version of items such as shingles offer the same protection and durability as ordinary asphalt shingles.

photovoltaic cell

Some solar cells are designed to operate with concentrated sunlight. These cells are built into concentrating collectors that use a lens to focus the sunlight onto the cells. This approach has both advantages and disadvantages compared with flat-plate PV arrays. The main idea is to use very little of the expensive semiconducting PV material while collecting as much sunlight as possible. But because the lenses must be pointed at the sun, the use of concentrating collectors is limited to the sunniest parts of the country. Some concentrating collectors are designed to be mounted on simple tracking devices, but most require sophisticated tracking devices, which further limit their use to electric utilities, industries, and large buildings.

photovoltaic cell

The performance of a solar cell is measured in terms of its efficiency at turning sunlight into electricity. Only sunlight of certain energies will work efficiently to create electricity, and much of it is reflected or absorbed by the material that make up the cell. Because of this, a typical commercial solar cell has an efficiency of 15%-about one-sixth of the sunlight striking the cell generates electricity. Low efficiencies mean that larger arrays are needed, and that means higher cost. Improving solar cell efficiencies while holding down the cost per cell is an important goal of the PV industry, NREL researchers, and other U.S. Department of Energy (DOE) laboratories, and they have made significant progress. The first solar cells, built in the 1950s, had efficiencies of less than 4%.

Photovoltaic Cells Are Still Very Green, Comparative Test Shows

Solar power generated by photovoltaic cells is among the greenest of energy options. The cells just sit there, basking in the sun and emitting nothing but electrons.

Emissions from Photovoltaic Life Cycles (Environmental Science & Technology)

But cells are manufactured, and the manufacturing process is not benign. Over the life cycle of solar cells — from the mining of raw materials to the finished product — just how green are they?

Vasilis M. Fthenakis of Brookhaven National Laboratory and colleagues have the latest analysis, to be published in Environmental Science and Technology. The short answer is that photovoltaic cells are still very green.

The researchers looked at emissions of greenhouse gases and pollutants like nitrogen oxide gases and heavy metals from the manufacture of four types of cells. Most of the emissions are results of the electricity used, and the amounts depend in part on the mix of electricity in the grid, or how much comes from coal plants, hydroelectric, nuclear and the like.

The researchers found that thin-film cadmium telluride cells were the greenest, although the differences among the four types were slight. All told, the researchers say, replacing electrical power from the grid with electricity generated by solar cells results in at least an 89 percent reduction in greenhouse gases and pollutants.

Introduction

For many years I've taught a course on science and technology from a historical perspective. The voracious appetite for energy by advanced societies and particularly the United States figures prominently in the course. I comment each semester that when humans are forced finally to stop using fossil fuels, either because of increasing costs or global pollution, there will still be plenty of energy from the sun, particularly in regions lucky enough to have cloudless days most of the year. One day my wife said to me, "Why don't you put your money where your mouth is?" So I did.photovoltaic panels-photovoltaic cell

The decision to install photovoltaic cell panels hinges on where one lives. The amount of sunlight as determined by the climate of one's location and the ability to receive the direct rays of the sun when it is shining helps one to decide if it makes sense to install the panels. On the left and right are images showing available sunlight for the United States and the world respectively. Although our location appears to be ideal because of the available sunlight per year, in actual fact our distance from the Pacific Ocean is only 12 km and coastal fog is a problem part of the year. On the average, the amount of sunlight we get is limited to between 5 and 8 hours per day throughout the year (see the blue strip along the coast in the left image in front of the arrow tip).photovoltaic panels-photovoltaic cell

Here is another image of the continental United States with a legend including units of kilowatt hours per square meter per day.

A roof sloping toward the south in full view of the sky would be ideal. However, our roof line slopes toward the east and the west. There is a chimney near the peak, as you can see.The panels have to be installed where there are no shadows during the day, so we installed our 2.5 kilowatt system on the east-sloping roof with an additional tilt toward the south. There are actually 18 panels each rated at 165 watts which brings the system to a theoretical maximum power output of 2970 watts or 2.97 kilowatts. The rating of 2.5 kilowatts may be due to the installing company knowing that the tilt of our panels would be less than ideal. Maximum output occurs around 11 am each day that the sun shines.
