My experience and my dentist said don’t be to tight with the toothpaste, put plenty (many don’t put enough). The author thanks NSF for funding his group’s research on iodine marine chemistry over his career, and Thomas Church and Timothy Ferdelman for suggesting the author’s initial foray into iodine chemistry. The author thanks the reviewers and guest editor, Rosie Chance, for their comments and constructive suggestions to improve the manuscript. Conflict of interest It is important to be flossing (cleaning between the teeth). We generally recommend flossing before brushing, but ultimately flossing at any time is better than not at all. The iO9 has a power adapter hardwired into the charging stand and a separate, detachable, adapter for the power2go case. The iO10 has just 1 detachable adapter for both the charging stand and power2go case. If the iO3 is potentially your first electric toothbrush you will notice the deeper and more effective clean it offers compared to a manual toothbrush. Do learn about the correct technique though, as it is different from a manual brush. It’s not as harsh on the teeth and gums as other Oral-B models

This work considers the thermodynamics of these transformations during the reduction of IO 3 −, which occurs in anoxic systems, during organic matter decomposition and by phytoplankton, as well as the oxidation of I -, which occurs by the direct oxidation of iodide by iodide oxidizing bacteria, oxidized metals and reactive oxygen species (ROS) that are produced by certain microbes, (macro)algae and abiotic processes including photochemistry. In a previous work (Luther, 2011), the chemistry and thermodynamics of chloride, bromide and iodide oxidation were compared; however, I(+3) species (HOIO, iodous acid, and IO 2 −, iodite) and stepwise iodate reduction were not considered. Here, stepwise reactions of the iodine species in equations 1a and 1b with environmentally important reactants (including transient ROS species) are considered for both the oxidation of I - and the reduction of IO 3 − to affect their interconversion. The kinetics of these stepwise reactions are also considered. Kinetic data for the first step(s) in iodide oxidation are available, but less kinetic information is available for iodate reduction. 2 Methods 2.1 Calculations of aqueous redox potentials from half-reactions The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Publisher’s note Each of the modes use different amounts of power from the motor. This impacts the angle of oscillation at the bristle tips to create brushing patterns and effects that are different from one another.Depending on the model you go for, you have the choice between 3, 4, 5, 6, or 7 brushing modes. 7 is the maximum number of cleaning modes available on any Oral-B brush. Oral-B has added value to the iO9 by including two additional brush heads for a total of four. The iO8 meanwhile, now comes with three brush heads in total.

For me, the fancy charging stand isn’t too big a factor. If bathroom visuals are important to you, maybe the magnetic stand is worth paying for. Otherwise, you can get by just fine with the cheaper stand.Of course, the table and quoted prices are just a guide. The actual selling prices vary from one retailer to another. Always MAXIMISE YOUR CLEAN with iO LIGHTRING TIMER -that has a dentist recommended 2-minute brush- and REFILL CHANGE ALERT Hybridization is the process in which hybrid orbitals are formed by mixing of same energy atomic orbitals.

To achieve healthy teeth you need to give all of them fairly equal attention, not just the ones at the front that are visible when you smile. Comparing Figures3, 4 indicates that the Mn 2+ and NO 2 − reactions with iodine species have a similar range of ΔlogK reaction values whereas the Fe 2+ reactions with iodine species are more favorable (higher ΔlogK reaction values). 3.5 Iodate reduction by sulfide Figures3– 6 showed the reduction of IO 3 − with reductants. All values of ΔlogK reaction> 0 indicate a favorable reaction and all values of ΔlogK reaction< 0 indicate an unfavorable reaction. These figures can be used to discuss the reverse reaction of I - oxidation with oxidants. For reverse reactions, when a ΔlogK reaction< 0, then I - oxidation is favorable, but when ΔlogK reaction> 0, I - oxidation is unfavorable. With a good oral care routine, like you are on the path to achieving, you shouldn’t need to use mouthwash at all. It can help at times you might not brush, so after lunch for example. In some instances, it may be recommended by dental professionals to be used as an extra tool to help keep the mouth clean, but it isn’t essential.You can change the cleaning mode on the iO5 before turning the brush on. You can’t do this on the iO4. The ground state outermost shell electronic configuration of I is 5s 25p 5. As we see from electronic configuration of I atom that there is only 1 unpaired electron and to form io3- ion 3 unpaired electron is required. In the excited state, I transfer 2 p electrons in 5d orbital and now a total of 5 unpaired electron is present.

Using mass spectrometry to evaluate atmospheric I xO y cluster and (nano)particle formation above seabed macroalgae, Sipilä etal. (2016) showed the stepwise formation of HIO 3 via HOI and IO•, which leads to (I 2O 5) x clusters (x=2-5) containing HIO 3 that result in iodine rich aerosol particles. These data on the formation of I 2O 5 aerosols agree with the exothermic ΔH reaction values of iodine oxide species reacting with O 3 and each other calculated using quantum mechanics ( Kaltsoyannis and Plane, 2008). Sipilä etal. (2016) also showed that cluster formation increased as a burst at low tide indicating significant I 2 release from the macroalgae (and subsequent oxidation) as found by Küpper etal. (2008). Hydration of I 2O 5 leads to two IO 3 −. In mass spectrometry laboratory studies, Martín etal. (2022) showed that new iodine containing (nano)particles and IO 3 − also form in the presence of NO 3 − and provide ΔH reaction data for the gas phase reactions involved. Experiments using the CERN CLOUD (Cosmics Leaving Outdoor Droplets) chamber documented the formation of HIO 3 via iodooxy hypoiodite, IOIO, as an intermediate ( Finkenzeller etal., 2022) and the fast growth of HIO 3 as (nano)particles ( He etal., 2021).

Thioethers can be oxidized to sulfoxides by periodate, and periodate is reduced to iodate The Series 3 has 3 cleaning modes (daily clean, sensitive & whitening) compared to the 4 of the Series 4 (daily clean, sensitive, super sensitive & whitening). The extra mode the iO4 has is super sensitive. The iO10’s pacer is often set to 20 second (sextant) intervals compared to the 30 second (quadrant) intervals of the iO9.

In the next sections (3.2 – 3.5), the thermodynamics for the conversion of iodate to iodide via the intermediates outlined in equations 1a and 1b by environmental reductants are considered to show what step, if any, in the reduction of iodate to iodide may be unfavorable over a wide range of pH. Iodate reduction is well known in the marine environment (e.g., Wong and Brewer, 1977; Wong etal., 1985; Luther and Campbell, 1991; Rue etal., 1997; Farrenkopf and Luther, 2002; Cutter etal., 2018) and occurs via chemical reductants like sulfide ( Zhang and Whitfield, 1986) and via microbes like Shewanella putrfaciens ( Farrenkopf etal., 1997) and Shewanella oneidensis ( Mok etal., 2018) during dissimilatory reduction coupled with decomposition (oxidation) of organic matter as well as phytoplankton mediated processes (e.g., Chance etal., 2007). 3.2 Iodate reduction by NO 2 -
