Nano tungsten needle is often used as a STM probe. And Most of the STM probes are nano tungsten needles. Wherein, nano tungsten needle is made of high-purity tungsten wire with good electrical conductivity and mechanical strength. According to the experts, STM (Scanning Tunneling Microscope) is different from XRD (X-Ray Diffraction), LEED (Low Energy Electron Diffraction) and other reciprocal space imaging using diffraction methods. STM can directly image the conductive sample in real space with atomic resolution, and has achieved…

Tungsten needle has the advantages of high hardness, high strength and strong ductility. And such a needle is not easy to rust and not easy to break with durability. While the tip of a steel needle is brittle and easy to fold, and the diameter of the tip cannot be processed to the micron level. So, tungsten needle is more suitable for inner ear anatomy than steel needle.

Do you know how to prepare tungsten needle efficiently? The experts have proposed a method for preparing tungsten needles with the advantages of high degree of automation, good repeatability and high efficiency. More details, please visit: http://tungsten.com.cn/tungsten-needles.html Utilizing the principle of electrochemical reaction, a linear motor is used to drive the tungsten wire up and down in the NaOH corrosion solution, so that the reaction proceeds between the anode tungsten wire and the cathode ring copper electrode. Wherein, the taper…

The quality of tungsten needle is directly related to the detection capability of the scanning electron microscope (STM). The size, shape and chemical identity of the tungsten tip affect not only the resolution and shape of the STM image, but also the electronic state of the measurement. Therefore, the preparation of tungsten tip is particularly important. And it had better to obtain a tungsten tip with a specific radius of curvature. More details, please visit: http://tungsten.com.cn/tungsten-needles.html There are some traditional…

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…
