It has been reported that only nano tungsten needle having sharp tip and single atom at the apex can provide stable and reliable atomically resolved imaging for applications of scanning tunneling microscopy (STM). Well, do you know how to prepare such a nano tungsten needle? Differing from the traditional methods, the experts have proposed a new method for preparing nano tungsten needles: More details, please visit: http://tungsten.com.cn/tungsten-needles.html The principle of the new preparation method is: On the basis of electrochemical…

STM probe is often a tungsten needle. STM is the abbreviation of scanning tunneling microscope. STM measures the electronic state distribution of the sample near the tip. The smaller the tip size of the tungsten probe, the higher the resolution, and the higher the imaging quality. More details, please visit: http://tungsten.com.cn/tungsten-needles.html It has been reported that for an STM, good resolution is considered to be 0.1 nm lateral resolution and 0.01 nm depth resolution. With this resolution, individual atoms within…

Tungsten needle with a sharp tip is often used as a probe for applying to scanning tunneling microscope, micro-pattern gases detector, and leak microstructure. More details, please visit: http://tungsten.com.cn/tungsten-needles.html Wherein, scanning tunneling microscope, abbreviated as STM, is a new type of detection instrument with atomic resolution, which has been widely used in the fields of physics, chemistry, biology, materials science, and microelectronics science. Micro-pattern gases detector (MPGD) is a gas particle detector that has been used in many fields such…

Tungsten needle is widely used as a probe for applications of scanning tunneling microscope (STM) – an instrument for imaging surfaces at the atomic level that is recognized as one of the world’s top ten scientific and technological achievements in the 1980s. More details, please visit: http://tungsten.com.cn/tungsten-needles.html It has been reported that the probe of scanning tunneling microscope can also be made of platinum wire, iridium wire, gold wire, silver wire and other metal materials with excellent conductivity, but platinum…

How to prepare tungsten needle by electrolytic method? The following materials are needed: Tungsten wire blank: Tungsten wire blank having a diameter of 1mm, thin tungsten wire blank having a diameter of 0.32mm and a length of about 5cm. Power supply: Two No. 1 batteries. After connecting the two batteries in series, two conductive copper wires are respectively welded to cathode and anode thereof. The anode is connected to tungsten wire to be processed, and the cathode is connected to…

Tungsten needle is an environmentally friendly and non-toxic consumable on medical high-frequency electric knife. The high-frequency current generated by the electric knife is used to cut and coagulate human tissues. Specifically, the high-frequency current forms high temperature, thermal energy, and discharge at the tip of the tungsten needle of the electric knife, which quickly dehydrates, decomposes, evaporates, and coagulates the blood of the contacted tissue to achieve the ding of decomposing the tissue and clotting, thereby achieving the purpose of…

Tungsten needle is a consumable of high frequency electric knife. Tungsten needle has an ultra-sharp needle point for precise cutting. Also, it has high melting point to withstand high temperatures above 3000 °C. So, such an electric knife is suitable for plastic surgery, neurosurgery, oral surgery, pediatric surgery, cardiothoracic surgery, and many other minimally invasive surgery. And the patients will recover relatively quickly as surgical wound is small. More details, please visit: http://tungsten.com.cn/tungsten-needles.html High frequency electric knife is an electrosurgical…

Tungsten needle is an elongated tungsten product made of pure tungsten or tungsten alloy, having the advantages of high temperature resistance, high hardness, and good conductivity. Tungsten needle can be used as an electrode material for argon arc welding (the fastest growing and most widely used welding technology at home and abroad), as a probe needle for detecting instrument, or as a dissection needle for various minimally invasive surgery. More details, please visit: http://tungsten.com.cn/tungsten-needles.html Wherein, tungsten needle electrode for argon…

Tungsten alloy shielding door has many unique excellent properties, such as high density, high strength, good radiation absorption performance, corrosion resistance, easy cutting processing, and environmental protection, etc., so it is suitable for applying to medical electron linear accelerator room to shield the X-rays and neutron rays, which are generated when the accelerator is working. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html According to the experts, when high-energy rays are emitted from medical linear accelerators, especially when high-energy X-ray beams directly hit…

Tungsten alloy radiation shield is more suitable for shielding X-rays and neutrons generated from the electron linear accelerator than lead radiation shield as tungsten alloy has high density of 16.5-18.75 g/cm3, which is 50% higher than lead. Also, tungsten alloy also has a strong ability to absorb rays, which is 30-40% higher than lead. In addition, tungsten alloy has environmental protection characteristics.
