This website is the first negative ions industry website in China, and its purpose is to rapidly promote the orderly development of the air negative ion (negative oxygen ion) industry. In 2020, the Tsinghua University successfully developed a medical-grade high-concentration negative oxygen ion generator.
A solid-state silicon battery or silicon-anode all-solid-state battery is a type of rechargeable lithium-ion battery consisting of a solid electrolyte, solid cathode, and silicon-based solid anode. [1] [2] In solid-state silicon batteries, lithium ions travel through a solid electrolyte from a positive cathode to a negative silicon anode. While ...
An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions , are particles with one or more extra electrons , conferring a net negative charge to the particle.
Negative ion products are products which claim to release negative ions and create positive health effects, although these claims are unsupported. [1] Many also claim to protect users from 5G radiation. These claims are likewise unsubstantiated. A market has developed for these products due to conspiracy theories about 5G. [2]
Positive and negative electrode vs. anode and cathode for a secondary battery. Battery manufacturers may regard the negative electrode as the anode, [10] particularly in their technical literature. Though from an electrochemical viewpoint incorrect, it does resolve the problem of which electrode is the anode in a secondary (or rechargeable) cell.
positive on left and negative on the right corner; negative on the left and positive on the right corner. Terminals can also be both on the long or short side of the battery, or diagonally opposed, or in the middle. Purchasing the wrong configuration may prevent battery cables from reaching the battery terminals.
In positive ion mode, DART produces predominantly protonated molecules [M+H] + and in negative-ion mode deprotonated molecules [M-H] −. Both negative and positive modes of DART provides relatively simple mass spectra. Depending on the type of analyte, other species may be formed, such as multiple charged adducts. DART is categorized as a soft ...
In the negative mode, [M−H] − ions are produced by either proton abstraction, or [M+X] − ions are produced by anion attachment. Most work on the APCI-MS analysis has been in positive mode. In the positive mode, when the discharge current of corona discharge is 1-5 μA on the nebulized solvent, N 2 gas molecules are excited and ionized ...
