Interfacial chemical bonding-mediated ionic resistive switching [PDF]
Scientific Reports, 2017 In this paper, we present a unique resistive switching (RS) mechanism study of Pt/TiO2/Pt cell, one of the most widely studied RS system, by focusing on the role of interfacial bonding at the active TiO2–Pt interface, as opposed to a physico-chemical ...

Reversible intercalation of methyl viologen as a dicationic charge carrier in aqueous batteries [PDF]
Nature Communications, 2019 Rechargeable batteries are governed by reversible intercalation reactions. Here the authors expand the intercalation chemistry to include methyl viologen as a large dicationic charge carrier in aqueous batteries.

Multiscale interface engineering enables strong and water resistant wood bonding [PDF]
Nature CommunicationsThe growing use of timber in construction has created an urgent need for high-performing engineered wood. Laminating timber facilitates production of structural components, but strong interfacial bonding is essential for engineered wood to outperform ...

A new model of chemical bonding in ionic melts [PDF]
The Journal of Chemical Physics, 2012 We developed a new physical model to predict macroscopic properties of inorganic molten systems using a realistic description of inter-atomic interactions. Unlike the conventional approach, which tends to overestimate viscosity by several times, our systems consist of a set of ions with an admixture of neutral atoms.

In-situ localised alignment assisted salting-out enhanced ionogels with high strength, toughness and impact resistance [PDF]
Nature CommunicationsIonic gels have promise in a range of applications but are limited in extreme environments. Here, we report a method for preparation of an ionic gel with improved mechanical properties, through the formation of a micro-orientated structure and increased ...

Analysis of Students’ Chemical Bonding Misconception with A Four-Tier Diagnostic Test
JTK (Jurnal Tadris Kimiya), 2022 Students had difficulty understanding the chemical bonding concept because of its complex and abstract nature. This difficulty could lead to chemical bonding misconceptions.

Journal of the American Chemical Society, 2023 Covalent and ionic bonds represent two fundamental forms of bonding between atoms. In contrast to bonds with significant covalent character, ionic bonds are of limited use for the spatial structuring of matter because of the lack of directionality of the electric field around simple ions. We describe a predictable directional orientation of ionic bonds

A family of ionic supersalts with covalent-like directionality and unconventional multiferroicity
Nature Communications, 2021 Binary ionic crystals, such as NaCl, are non-polar due to directionless ionic bonding interactions. Here, the authors show that polarity can be developed by using superalkali/superhalogen ions as building blocks, leading to ionic supersalts with ...
