US researchers successfully designed artificial power cells

Release date: 2008-10-24

Researchers at Yale University in the United States have successfully designed artificial cells with extraordinary power generation capabilities that are expected to be used in the future to power tiny medical devices transplanted into the human body.
It is reported that the researchers' research inspiration originated from the power generation cells that can generate energy in the electric raft. Electrophoresis is the conversion of chemical energy obtained from food into electrical energy. There are thousands of cells in the body, with a maximum voltage of 600 volts. The researchers envisioned the possibility of designing artificial power cells as potential sources of power.
The researchers designed artificial cells that mimic the power generation of power cells. The model they built showed that artificial cells generated 28% more electricity than electric power cells, while chemical energy was converted to electrical energy by 38%. It is possible to use dozens of human cells to make thin micro-biobatteries and use them to drive tiny devices that are transplanted into the human body. Xu Jian, a principal participant in the study, said: "We wanted to see if natural cells have achieved maximum energy output and energy conversion efficiency. But it turns out that artificial cells can actually surpass natural cells, which is really surprising. ."
Although the researchers have now designed artificial cells, there is still a considerable distance from the actual artificial cell construction. One of the more critical problems is the source of power that artificial cells need before they generate electricity. Researchers envision that these artificial cells can be powered in a way similar to natural cells, such as allowing bacteria to regenerate batteries using blood glucose recycling ATP. With the power, artificial cells may one day replace batteries to drive tiny devices transplanted into the human body. Xu Jian said that the advantage of a bio-battery made up of artificial cells is that it does not leave harmful substances in the human body after it fails. It is like any other cell in the body. ——Shanghai Medical Device Industry Association

Art Box is  a decorative box with artistic style.Art box is an extension of the social needs of a functional package. Therefore, it not only has the function of packaging but also highlights some of its functions to a certain extent. The exquisiteness of the gift box is proportional to the increase of the value of the commodity, which to a certain extent weakens the value of the use of the commodity.

material:
Box according to the packaging material points: a paper products, plastic products, metal, bamboo packaging, glass containers and composite materials, the general choice of gift box paper packaging, which is related to China's traditional culture, our hearts have a romantic Feelings, as if this can express the solemn feelings of the heart.

And promote green packaging, paper is undoubtedly the most appropriate choice, production and processing simple packaging waste recovery rate is also high.

In the protection of goods and general packaging is almost the same, in order to highlight the value of the use of more expensive and beautiful lining to protect the goods, such as silk.

In the circulation is not as convenient as the general packaging, the value of the gift is relatively high, the cost of circulation must be high, such as collision avoidance, deformation-free and so on. In the beautification of goods to attract customers is undoubtedly have a super high influence.

It has decorative use at the same time can store some small items.
