    1. ATP

      ATP better known as Adenosine triphosphate is an energy carrying molecule found in all living things cells. ATP takes the chemical energy from the process of breaking down food molecules to releases it as fuel for cellular processes.

    1. C7H16(l)+O2(g)→CO2(g)+H2O(g)(3.1.4)(3.1.4)C7H16(l)+O2(g)→CO2(g)+H2O(g) C_7H_{16} (l) + O_2 (g) \rightarrow CO_2 (g) + H_2O (g) \label{3.1.3} The complete combustion of any hydrocarbon with sufficient oxygen always yields carbon dioxide and water. Figure 3.1.23.1.2\PageIndex{2}: An Example of a Combustion Reaction. The wax in a candle is a high-molecular-mass hydrocarbon, which produces gaseous carbon dioxide and water vapor in a combustion reaction (see Equation 3.1.43.1.4\ref{3.1.3}). Equation 3.1.43.1.4\ref{3.1.3} is not balanced: the numbers of each type of atom on the reactant side of the equation (7 carbon atoms, 16 hydrogen atoms, and 2 oxygen atoms) is not the same as the numbers of each type of atom on the product side (1 carbon atom, 2 hydrogen atoms, and 3 oxygen atoms). Consequently, the coefficients of the reactants and products must be adjusted to give the same numbers of atoms of each type on both sides of the equation. Because the identities of the reactants and products are fixed, the equation cannot be balanced by changing the subscripts of the reactants or the products. To do so would change the chemical identity of the species being described, as illustrated in Figure 3.1.33.1.3\PageIndex{3}. Figure 3.1.33.1.3\PageIndex{3}: Balancing Equations. You cannot change subscripts in a chemical formula to balance a chemical equation; you can change only the coefficients. Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties. For example, water (H2O) and hydrogen peroxide (H2O2) are chemically distinct substances. H2O2 decomposes to H2O and O2 gas when it comes in contact with the metal platinum, whereas no such reaction occurs between water and platinum. The simplest and most generally useful method for balancing chemical equations is “inspection,” better known as trial and error. The following is an efficient approach to balancing a chemical equation using this method.

    1.  Chemical informatics for facilitating international collaboration This activity aims at creating a working group of scientists to collaboratively source, collate, and analyse data with unique chemical signatures. It seeks to compile data collected from a broad range of routine chemical monitoring activities that contain chemical signatures (e.g. data collected from atmospheric monitoring, environmental sample collection, water testing, and more). The intent is to connect chemical and information scientists from different regions of the world to create a hub in which the information can be disseminated to the collaborators for visualisation and informative analysis of global and regional chemistry. This work is intended to facilitate engagement of the Technical Secretariat with the scientific community. Main output will be a data collation centre serving as a hub for collating and reducing data into formats compatible with the analytical tools used by the collaborating researchers. The hub, located in one of the participating universities, will support the network of collaborating scientists and build its capacity to expand beyond the implementation period.

      I believe a small EU grant has been awarded to look into this, although the funds are not available for us, we could support this, and piggy back off of it.

    1. Two new molecular catalysts of water oxidation have been synthesized by a team of brilliant scientists from the U.S. Department of Energy’s Brookhaven National Laboratory. These new molecular catalysts – complexes of ruthenium which are surrounded by the binding molecules, and they contain phosphonate groups.
