Researchers from the University of California, Los Angeles and Arizona State University (USA) have successfully designed solar cells capable of bending towards sunlight, like the activity effect of sunflowers, through the use of intelligent nanotechnology.
By fabricating special materials into thin structures, scientists have created “small stalks” that bend toward the light source, providing the basic foundation for improving the efficiency of energy technologies. amount of sun in the future.

Being able to “chase” the sun is useful for photoelectric activity – which works best when “bathed” in the dense light of radiation that is directed at the surface, rather than slowly. a “shallower” angle. In fact, compared to rays from an overhead light source, light hitting an angle of about 75 degrees carries less energy.
To solve the problem of “loss of energy density” at an inclined angle, the team turned to gels and polymers that react with light or heat.
Researchers assembled tiny artificial plants and submerged them in water. Using laser beam projection, the artificial stalks responded quickly to the warmth of the light, shrinking on one side and expanding on the other to cause the thread to twist and lean toward the laser. , similar to the effect of a sunflower towards the light.
The amount of light converted to heat was then determined by measuring water vapor, changes in the amount of steam that indicated the artificial plants gained energy at steep angles four times that of a flat, stationary surface.
Sunflower seeds are loaded with healthy fats, known as polyunsaturated fats. According to the American Heart Association, polyunsaturated fats can lower bad cholesterol (LDL) levels, reduce the risk of heart attack, stroke, and control blood sugar.
Sunflower seeds contain 100 different enzymes that regulate the hormonal balance in the body. For women, in particular, the enzymes in the seeds can balance the production of estrogen and progesterone, which has been shown to be helpful in controlling PMS symptoms, thyroid and morning sickness. usually occurs during the first trimester of pregnancy. Vitamin B6 contained in the seeds helps in protein synthesis, metabolism, and promotes body balance.
In addition to healthy fats, sunflower seeds are also nutritious thanks to a rich source of vitamins along with a high content of minerals such as copper, manganese and selenium and phosphorus. Vitamin E and selenium act as antioxidants, helping to prevent free radicals from damaging healthy cells in your body. In particular, selenium is this mineral that is important for DNA reproduction and synthesis. Phosphorus helps strengthen bones), copper helps strengthen the immune system of the heart.
Sunflower seeds are notably rich in magnesium, a mineral involved in more than 300 different body functions. Magnesium can lower blood pressure, control blood sugar and reduce the risk of cardiovascular disease. It is also an important component of bone that helps regulate nerve and muscle function.
Niacin in sunflower, also known as vitamin B3, helps repair DNA, lower cholesterol and lower your risk of heart disease. Water-soluble vitamin B6 also helps the body to create norepinephrine and serotonin, chemicals that transmit brain signals.
Another sunflower seed benefit is, it helps in alleviating symptoms associated with constipation and irritable bowel syndrome (IBS). The enzymes present in the seeds regulate the secretion of digestive juices and remove unnecessary toxins from the Sunflowers god says you are unique special lovely precious strong chosen shirt body, ensuring that your stomach and intestines are functioning properly.
100 grams of seeds contain about 6 grams of protein and 2.5 grams of fiber. These substances work to help keep the Sunflowers god says you are unique special lovely precious strong chosen shirt intestinal wall healthy and build muscle. If you are a woman of childbearing age, folate in the Sunflowers god says you are unique special lovely precious strong chosen shirt direction is very important. This B vitamin has the ability to prevent neural tube defects such as spinal bifida and anencephaly, improve memory, heart health and prevent cancer.
When eating sunflower seeds, eat right from the bag, avoid long, the Sunflowers god says you are unique special lovely precious strong chosen shirt seeds will be blotchy, musty … This type of seed can also be combined with many other dishes such as adding to green salad, fruit salad tree, tuna salad …, stir in the morning oatmeal, add to smoothies, sprinkle with yogurt cream for delicious, nutritious dish.
Processed sunflower seeds are loaded with salt, either by roasting, peeling, or seasoning. Experts note that too much salt in the Sunflowers god says you are unique special lovely precious strong chosen shirt diet can affect the kidneys. In order for this seed to be effective, it should be eaten raw, not seasoned with salt.
