Abstract:
Silver gallium sulfide (AgGaS2), silver gallium selenide (AgGaSe2), and silver gallium indium selenide (AgGaxIn(1 − x)Se2) are unique nonlinear crystals suitable for a wide range of three-wave mixing applications. They combine strong nonlinear coupling with phase matching across a wide (0.5 − 12.5 μm) transmission range. These properties provide the basis for CO2 laser harmonic-generator (HG), visible (VIS), and near-infrared (NIR) pumped opticalparametric-oscillator (OPO) and sumand difference-frequency-generator (SFG/DFG) systems for producing tunable laser radiation from approximately 0.65

School of Advanced Sciences, VIT University, Vellore-632 014, Tamilnadu, India <em>E-mail</em> : rezhilvizhi@vit.ac.in, revizhi@gmail.com The organic nonlinear optical crystal 4-chloroaniline was grown from methanol at room temperature by low temperature solution growth method. Powder X-ray diffraction was studied to confirm the grown crystal structure. The cutoff wavelength for the grown crystal was observed at 325 nm and the band gap energy of 3.814 eV was determined by recording the UV-Vis-NIR spectrum analysis. The presence of different functional groups of 4-chloroaniline were identified

Abstract:
Ag nanoparticles (AgNPs) were biosynthesized using sage (Salvia officinalis L.) extract. The obtained nanoparticles were supported on SBA-15 mesoporous silica (S), before and after immobilization of 10% TiO2 (Degussa-P25, STp; commercial rutile, STr; and silica synthesized from Ti butoxide, STb). The formation of AgNPs was confirmed by X-ray diffraction. The plasmon resonance effect, evidenced by UV-Vis spectra, was preserved after immobilization only for the sample supported on STb. The immobilization and dispersion properties of AgNPs on supports were evidenced by TEM microscopy, energy-disp

In this study, pomegranate (Punica granatum L.) leaf extract and 2% (w/v) aqueous solutions isolated by SFE extraction and microwave extraction were used to create silver nanoparticles (AgNPs). The pomegranate was grown in Turkey's Eastern Black Sea region. AgNO3 solution (0.25, 0.5, and 1 mM) received separate additions of 0.1 and 0.2 mL extract before being microwave-irradiated. Ag nanoparticles made using green chemical techniques were characterized by UV-Visible, , XRD, TEM, Zetasizer and FT-IR.

Abstract:
This review takes a look at the latest ways to get and analyze plant-based compounds, with a focus on being eco-friendly and practical. Supercritical fluid extraction (SFE) uses CO₂, which helps increase yields while using less solvent and keeping the plant’s molecules intact. Ultrasound-assisted extraction (UAE) uses sound waves to break down cell walls, making it easier to recover sensitive compounds quickly and with less solvent. Microwave-Assisted Extraction (MAE) heats the solvent directly, speeding up the process compared to traditional methods. For analyzing plant chemicals, high-resolu

I materiali bidimensionali costituiti da atomi metallici incorporati in una struttura organica (2D-MOF) stanno guadagnando sempre più interesse nel panorama della scienza delle superfici. La loro dimensionalità consente in maniera naturale di sfruttare le tante tecniche sperimentali con sensitività superficiale, che consentono di studiare in dettaglio la loro geometria, struttura elettronica e reattività chimica. L’ambiente chimico locale dei siti attivi li rende infatti catalizzatori a singolo atomo ideali per lo studio della catalisi eterogenea. In questa tesi, ci si è concentrati sulla cres

The investigations are performed with the aid of specific in situ techniques (IR-Vis SFG, NAP-XPS, etc.) in order to probe the structural, electronic, chemical and catalytic properties of the models. The latter span from ordered lattices of metal nanoparticles to 2D metallorganic crystals, where stabilized mono-metallic centers act as the active cores. These syst

Abstract:
Real-time analysis may be the most underappreciated Principle of Green Chemistry, yet its importance cannot be ignored. Every chemical process requires analysis, whether before, during, or after. Continuous-flow processes offer opportunities for real-time analysis just about anytime and anywhere during the process. Performing analysis in real-time requires consideration of what parameters are appropriate to monitor. Physical parameters include temperature, pressure, heat, pH, or light. Chemical parameters include reactants, intermediates, products, or by-products. Soltex developed a continuous

Abstract Past and present directions in corrosion characterization research using optical spectroscopy are discussed. Future directions using optical techniques are then presented. Information from optical spectroscopies can be used to understand fundamental corrosion processes. Five optical experimental techniques were selected for work to date; infrared (IR), Raman, ellipsometry, ultraviolet-visible (UV-VIS), and second harmonic generation (SHG) spectroscopies. Emphasis is placed on the applications of these techniques to solve relevant corrosion problems, including ex situ and in situ studi
