According to the Yonhap news agency reported on Sept. 22, Professor Kim Tae-Ho, a professor of chemical engineering at Pohang University of Science and Technology, and Li Junyu, an integrated course team, used food additives made from walnut flavoring to produce an environmentally friendly and highly efficient conductive substance that could be used Production of perovskite solar cells. The results have been published on the online edition of the Journal of the American Chemical Society, the authoritative journal of chemistry.
It is reported that perovskite material thinner than silicon, production costs are also cheaper, so much attention in the solar cell industry. Reported that the perovskite solar cells in the sunlight received, it will produce electronic and electron holes, then you need an efficient medium to transmit them to the electrode. Prior to this, the conductive medium of perovskite solar cells has been using toxic chlorobenzene.
The research team successfully developed a more environmentally friendly conductive material using walnut flavor food additives, can replace chlorobenzene to make perovskite solar cells. Li Junyu said that this material can improve the polymer efficiency by 18% without changing the optoelectronic properties, and this efficiency will not subside with time. This discovery is expected to contribute to the development of conductive polymer industry.
Round fixing magnet, or bushing fixing magnet, socket bushing magnet or Insert magnet holder.The round fixing magnet, is a magnetic insert assembly mainly used for holding concrete formworks which made of steel,or holding tools. Its` magnetic force is range from 4 kg ~ 70kgs, which could hold steel structures steadily.
The Round fixing magnet, is made of Neodymium Magnet, steel armature and steel thread rod. The neodymium magnet is plated with NI-CU-NI treatment,the steel armature is treated with Zinc coating, the thread rod is coated with black epoxy. These surface treatment could offer good anti corrosion protections for the bushing fixing magnets.
The inserted fixing magnet consists of cup magnet /base magnet and a separable thread rod. To make sure the adequate pull force,The strongest permanent magnet-NdFeB magnets are used in the embeded socket fixing magnet. The NdFeb magnet are plated with NiCuNiand the metal cup could be plated with color Zinc or other treatments to well protect the metal cup from corrosion. The magnet contact surface should be clean and flat otherwise the actual magnetic force will be reduced. The max working temperature of the embeded fixing
magnets is 80 degrees. Please keep the embeded fixing magnets away fire or being heating. If higher working temperature is needed, the
higher grade NdFeB magnets will be necessary then.The magnetic force and sizes could be designed according to customers' requirements.
Magnetic bushing assembly, bushing magnets, bush magnets or magnet bush assembly,are used for retaining tools, lights,signs, and other heavy objects.
Bushing magnet, which configure by a thread hole cup magnet and a separable thread rod to fit the thread hole.Magnetic bushing magnet is made of a strong neodymium magnet,a steel cup and a thread rod. The magnet have been plated with thick coatings to prevent corrosion,please be noted that magnetic bushing assembly is not water proof,bushing magnet could not left in humid environment for months or years.Bushing magnet assembly have very strong magnetic force which could retaining heavy objects.We could produce various sizes of magnet bush assembly. Please kindly inform the model number and quantity when send us inquiry,we could quote soon after calculate the costs.
inserted fixing magnet, a strong magnetic assembly for precast concrete industry, it is used to hold neodymium magnet
Inserted fixing magnet,also known as embeded fixing magnet, inserted socket fixing magnet, embeded socket fixing magnet, magnetic pipe ixing magnet,precast concrete fixing magnet.is the new magnetic assembly in precast concrete industry. It is the best solution to fix the
inserted socket in precast concrete panel.
