Solid State Synthesis of Mixed-Metal Oxides Scientific Manuscript
This scientific manuscript describes a study aimed at synthesizing novel inorganic solid phase materials using high temperature reactions. Specifically, the researchers predicted and calculated 10 reactions involving mixed metal oxides from groups 14/15, 14/14, and 15/15 of the periodic table. They determined the stoichiometry and predicted possible products for each reaction. However, due to limitations including a non-functional oven, they were unable to carry out the high temperature synthesis part of the project to obtain crystalline solid products.

The document describes an experiment to investigate the correlation between ligands (Cl−, NH3, H2O, OH−) and the wavelength of light absorbed by transition metal complexes. Transition metal complexes of Cu2+, Co2+, Fe2+, Cr2+ were made using the different ligands. A colorimeter was used to measure the wavelength absorbed for each complex. The results showed the wavelength absorbed was longest for Cl− ligand and shortest for NH3 ligand for all metal complexes. This trend was consistent with the hypothesis and previous research that ligand type affects d-orbital splitting and thus the energy of electronic transitions determining color.
Effect of cu co mixed metal oxides on the combustion of psan-htpb based solid...
Abstract Composite propellants based on ammonium perchlorate (AP) as oxidizer are state-of-the-art. However, global environmental impact restricts AP-based propellants because of their high chlorine exhaust. Therefore, efforts are on to innovate propellants with clean exhaust. Ammonium nitrate (AN) has, thus, regained importance in the field of propellants and explosives, more specifically in insensitive formulations, because of its clean burning and low hazard. However, the stumbling block for the application of AN - as solid propellant oxidizer has been its dimensional instability caused by phase transformation which results in increase of volume and porosity of the propellant grain. This can be overcome by the use of phase stabilized ammonium nitrate (PSAN). In the present study AN phase stabilized by incorporating 10% KN to prepare composite solid propellant. Copper-Cobalt mixed metal oxides have been synthesized via citric acid complexing method. Three different catalysts were prepared with different Cu-Co molar ratios 1, 0.5 And 2 in the initial reactants. The synthesized catalysts were then added to the PSAN-HTPB(Phase Stabilized Ammonium Nitrate- Hydroxyl Terminated Poly-Butadiene) composite formulations. These propellant samples were subjected to burn rate measurement in a Crawford High Pressure Strand Burner and thermal degradation studies in Simultaneous Thermal Analyzer (STA). The thermal decomposition and burn rate of the propellant is observed maximum on the addition of Copper-Cobalt mixed metal oxide catalyst with molar ratio 2. A total of six propellant samples catalyzed and non-catalyzed and one preheated virgin sample were undertaken for the above analysis and results obtained are discussed. It has been observed that except the propellant sample with Cu-Co-III and virgin propellant where PSAN was prepared by solid mixing, other propellant samples were hard to burn. KeyWords:Solid propellants, Ammonium nitrate, Phase stabilization, Burn rate, Thermal decomposition, Mixed metal oxides, Catalytic combustion.

1. The student investigated the effect of increasing concentrations of the enzyme inhibitor copper(II)sulfate (0.2, 0.4, 0.6, 0.8, 1.0 mol/dm3) on the activity of the enzyme catalase, measured by the amount of oxygen released during the decomposition of hydrogen peroxide using a data logger.
2. It was hypothesized that there would be a negative correlation between the amount of oxygen released and the concentration of copper(II)sulfate, as the inhibitor would decrease the reaction rate.
3. The results showed that the mean amount of oxygen released decreased with increasing concentrations of copper(II)sulfate at 120, 90, and 60 seconds
Catalyst on-the-rate-of-reaction-teacher’s-guide
The document discusses how the amount of catalyst affects the rate of reaction. It describes two experiments:
1) Using 0.2g of manganese (IV) oxide powder as the catalyst.
2) Using 0.8g of manganese (IV) oxide powder as the catalyst.
The results show that with more catalyst (0.8g), the rate of reaction is faster as shown by the higher volume of oxygen gas liberated over time. Increasing the amount of catalyst increases the rate of reaction.

SCO Final Poster to print
This research studied the effects of iron and scandium doping on the crystal structure and oxygen evolution reaction (OER) performance of strontium cobalt oxide (SCO) electrocatalysts. X-ray diffraction showed that doping caused the SCO crystal structure to shift from hexagonal to cubic. Testing found that iron-doped SCO lowered the OER overpotential by 40 mV and achieved water oxidation at 410 mV, performing better than undoped SCO. While crystal structure changes with doping, OER performance correlated more with the catalytically active dopant metal than structure. Iron-doped cubic SCO also exhibited greater stability during testing.

The electrocatalytic activity of the spinel oxide LiMn1.5Ni0.5O4 with
different morphologies (cubic, spherical, octahedral, and truncated octahedral) has been
investigated for the oxygen evolution reaction (OER) in alkaline solutions that is of
interest for metal−air batteries. The OER activity increases in the order truncated
octahedral < cubic < spherical < octahedral, despite a larger surface area (2.9 m2 g−1) for
the spherical sample compared to nearly similar surface areas (0.3−0.7 m2 g−1) for the
other three samples. The high activity of the octahedral sample is attributed to the
regular octahedral shape with low-energy {111} surface planes, whereas the lowest
activity of the truncated octahedral sample is attributed to the high-energy {001} surface
planes. The octahedral sample also exhibits the lowest Tafel slope of 70 mV dec−1 with
the highest durability whereas the truncated octahedral sample exhibits the highest Tafel
slope of 120 mV dec−1 with durability similar to the cubic and spherical samples. The
study demonstrates that the catalytic activities of oxide catalysts could be tuned and
optimized by controlling the surface morphologies/planes via novel synthesis approaches.

- The document examines the corrosion behavior of API 5L X42 carbon steel samples immersed in sodium chloride (NaCl) and sodium carbonate (Na2CO3) solutions of different concentrations (0.5M and 1.0M) for 1008 hours.
- Experimental results showed the highest corrosion occurred in the 1.0M Na2CO3 solution, as this environment did not form a protective film on the steel samples. The next highest corrosion was in the 0.5M NaCl solution.
- Generally, corrosion rates were higher in environments like Na2CO3 that do not form protective oxide films, and increased with higher concentrations. Corrosion was lower in environments like NaCl that can form

The electrocatalytic activity of the spinel oxide LiMn1.5Ni0.5O4 with
different morphologies (cubic, spherical, octahedral, and truncated octahedral) has been
investigated for the oxygen evolution reaction (OER) in alkaline solutions that is of
interest for metal−air batteries. The OER activity increases in the order truncated
octahedral < cubic < spherical < octahedral, despite a larger surface area (2.9 m2 g−1) for
the spherical sample compared to nearly similar surface areas (0.3−0.7 m2 g−1) for the
other three samples. The high activity of the octahedral sample is attributed to the
regular octahedral shape with low-energy {111} surface planes, whereas the lowest
activity of the truncated octahedral sample is attributed to the high-energy {001} surface
planes. The octahedral sample also exhibits the lowest Tafel slope of 70 mV dec−1 with
the highest durability whereas the truncated octahedral sample exhibits the highest Tafel
slope of 120 mV dec−1 with durability similar to the cubic and spherical samples. The
study demonstrates that the catalytic activities of oxide catalysts could be tuned and
optimized by controlling the surface morphologies/planes via novel synthesis approaches.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
