In this scientific research, we synthesized the novel CaO-CdO/ZSM-5 zeolite nanocomposite adsorbent and studied the effects of different parameters on the adsorption of Pb2 ions from water media for the first time. About 99.2% adsorption removal efficiency was obtained after a contact time of 60 min and an adsorbent amount of 0.1g/L for an initial Pb2 concentration of 200mg/L at pH 8 and temperature of 60oC. The adsorption kinetic fit well via the pseudo-second-order model. Furthermore, the adsorption results were reproduced using the Langmuir isotherm with a maximum adsorption capacity of mg/g. The thermodynamic data displayed that the adsorption of Pb2 ions over the CaO-CdO/ZSM-5 nanocomposite was endothermic and spontaneous.   #CaOCdOZSM5 #Zeolite #Nanocomposite #Pb2ions #Adsorption   #Chemistry #OrganicChemistry #InorganicChemistry #PhysicalChemistry #AnalyticalChemistry #Biochemistry #TheoreticalChemistry #EnvironmentalChemistry #ChemicalEngineering #PolymerChemistry #MedicinalChemistry #IndustrialChemistry #GreenChemistry #ChemicalSynthesis #ChemicalKinetics #Spectroscopy #Electrochemistry #Nanochemistry #SurfaceChemistry #QuantumChemistry #ChemicalBonding #Thermodynamics #ChemicalCatalysis #SupramolecularChemistry #MaterialsChemistry

#Review The Molecular Basis of Organic Chemiluminescence by Maidileyvis Castro Cabello, Fernando H.Bartoloni, Erick Bastos and Wilhelm Baader https://lnkd.in/ghhBnQJK   #MDPI #Chemiluminescence #Bioluminescence #Molecula #biosensors #sensors #openaccess   #Abstract Bioluminescence (BL) and chemiluminescence (CL) are interesting and intriguing phenomena that involve the emission of visible light as a consequence of chemical reactions. The mechanistic basis of BL and CL has been investigated in detail since the 1960s, when the synthesis of several models of cyclic peroxides enabled mechanistic studies on the CL transformations, which led to the formulation of general chemiexcitation mechanisms operating in BL and CL. This review describes these general chemiexcitation mechanisms—the unimolecular decomposition of cyclic peroxides and peroxide decomposition catalyzed by electron/charge transfer from an external (intermolecular) or an internal (intramolecular) electron donor—and discusses recent insights from experimental and theoretical investigation. Additionally, some recent representative examples of chemiluminescence assays are given.

We are thrilled to announce our latest publication for October 2024: "Improving Redox Reactions of Spiro-OMeTAD via P-Type Molecular Scaffold to Reduce Energy Loss at Ag-electrode in Perovskite Solar Cells" which has been published in: Journal of Energy Chemistry (Elsevier). Q1 - WoS Journal - SCIE - Impact Factor, 14.0 (2023). In this study, we introduced a crystalline additive (CA) to regulate the redox process of Spiro and its interface with an Ag electrode. Our findings indicate that CA functions as a molecular scaffold, improving the crystallinity and stability of radicals in Spiro throughout the entire redox reaction. This enhancement increases the hole mobility of Spiro and strengthens the internal electric field, thereby improving hole extraction and transport efficiency at both interfaces. Moreover, the optimized redox reaction of Spiro reduces energy loss at the Ag electrode, significantly boosting the power conversion efficiency to 25.21%. 👉 Check out the link for article: https://lnkd.in/gF-gvCqD

The balances: f1 = f(H) and f2 = f(O) are the basis to formulate the linear combination f12 = 2∙f2 – f1 = 2∙f(O) – f(H).   #Electrolyticredoxsystems #GATESGEB #ApproachItoGEB #ApproachIItoGEB #Potentiometrictitration #Chemistry #OrganicChemistry #InorganicChemistry #PhysicalChemistry #AnalyticalChemistry #Biochemistry #TheoreticalChemistry #EnvironmentalChemistry #ChemicalEngineering #PolymerChemistry #MedicinalChemistry #IndustrialChemistry #GreenChemistry #ChemicalSynthesis #ChemicalKinetics #Spectroscopy #Electrochemistry #Nanochemistry #SurfaceChemistry #QuantumChemistry #ChemicalBonding #Thermodynamics #ChemicalCatalysis #SupramolecularChemistry #MaterialsChemistry

🔬 Interesting molecular level observation in polyelectrolyte coacervate stabilization research! Ever wondered how to keep those tiny membraneless droplets formed via Liquid-liquid phase separation in polyelectrolyte solutions from merging? Here's a simple yet effective trick: Just transfer your coacervates to distilled water! But why does this work? Our recent study at the Zerze group, University of Houston, reveals the molecular magic behind this phenomenon. In our latest paper "The molecular picture of the local environment in a stable model coacervate" (https://lnkd.in/gwCXAUQm) we uncover how changing the ionic environment dramatically alters the dynamics and structure of coacervates. This change is key to boosting their stability against coalescence.

The computation of electronic excitation energies of atoms and molecules via the Bethe Salpeter equation (BSE) has attracted considerable attention in recent years. In the present Software News and Update, we report on the implementation of the BSE approach in the TURBOMOLE program using a resolution-of-the-identity (RI) approximation for all two-electron electron-repulsion integrals that are required for solving the BSE.
