Summary: The scalable synthesis of saturated heterocyclic dimethyl phosphine oxides was achieved through key steps involving reactions of HP(O)Me-2, palladium-catalyzed reactions, and base-mediated nucleophilic substitutions. Introduction of the P(O)Me-2 group significantly affected the compound's basicity, hydrophilicity, and aqueous solubility. This method shows potential for generating lead-like three-dimensional compound libraries as confirmed using the LLAMA tool.

Summary: The use of electrical plants and grids for power generation and transmission requires an effective mechanism for energy storage. This can be achieved through the use of electrical energy storage devices such as batteries and supercapacitors. Rational design of new materials on an atomic level, including chemical composition, structure, morphology, and heterointerfaces, is crucial for developing batteries with improved performance for specific applications. A synthesis strategy called the chemical preintercalation synthesis approach is introduced in this Account, which allows for the preparation of new intercalation host oxides, hybrid materials, and compounds with oxide/carbon heterointerfaces as electrodes in intercalation batteries. The approach allows for the control of material properties at the atomic level and opens pathways for the preparation of materials with advanced functionalities.

Summary: In this study, tetranuclear [Fe2S2] hydrogenase mimic complexes containing Pt(II), Ni(II), and Ru(II) complexes were synthesized and their electrochemical properties were investigated. The incorporation of metal complexes in the structure modulated the electronic communication between the redox-active [Fe2S2] centers. Specifically, the structure of the phosphine ligand in the Pt compounds played a crucial role in facilitating or hindering the electronic communication, while the addition of a Ru-bis(bipyridine) complex promoted the communication. These experimental and computational findings provide insights into the electronic interaction between redox-active centers in hydrogenase.

Summary: In this study, symmetrical chloride-functionalized Anderson type POM was used as a building block for further POM post-functionalization with organic pyrene compounds. Two novel organic-inorganic hybrid pyrene-POM compounds were designed, synthesized, and fully characterized. The photophysical and electrochemical properties of these compounds were investigated. The organic-inorganic hybrids retained the unique photophysical properties of their precursor pyrene compounds while the functionalization of inorganic POM moiety with organic bis-pyrene compound influenced the redox properties of the Mn-Anderson core.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.

Summary: This study focuses on the corrosion characteristics of AA 7075 and AA 7075 based hybrid composite fabricated using stir casting and hot rolling techniques. The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
