Experiments with bifluoride ions show evidence of hybrid bonds

Hydrogen bonds. (A) Types of hydrogen bonds depending on donor-acceptor distance. Potentials of proton motion are shown along with the first three quantum levels and the associated lowest-energy transitions. (B) Principal coordinates of any H-bond demonstrated with HF2−(aq): donor-acceptor distance (dFF), proton asymmetry (Δ), and linearity (δ). Credit: Science (2021).

Hybrid chemical bonds are a mash-up of hydrogen and covalent bonds

fluorine atoms bonded to hydrogen atom

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise questions about how chemical bonds are defined, chemists report in the Jan. 8 Science. Hydrogen bonds are typically thought of as […]

Powerful graphene hybrid material for highly efficient supercapacitors — ScienceDaily

A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries. Usually, energy storage is associated […]

Zinc-ion hybrid capacitors with ideal anions in the electrolyte show extra-long performance — ScienceDaily

Metal-ion hybrid capacitors combine the properties of capacitors and batteries. One electrode uses the capacitive mechanism, the other the battery-type redox processes. Scientists have now scrutinized the role of anions in the electrolyte. The results, which have been published in the journal Angewandte Chemie, reveal the importance of sulfate anions. Sulfate-based electrolytes gave zinc-ion hybrid […]
