Organic-inorganic hybrid perovskite solar cells (PSCs) have received extensive attention due to their high power conversion efficiency, bright prospects for large-scale deployment, and low cost. However, the end-of-life lead (Pb)-based PSC will pose significant resource and environmental challenges. Herein, we develop an eco-friendly strategy, the molten-salt-electrolysis (MSE), to recover Pb and iodine (I₂) from spent Pb-based PSC. First, lead iodide (PbI₂) was dissolved in molten LiCl-KCl and then electrochem. converted into I₂ at a graphite anode and Pb at the cathode. The recovery efficiency of Pb reached 97.65% with a high current efficiency of 96.87%. In addition, a high PbI₂ leaching rate of ∼ 99.8% and a high PbI₂ solubility of ∼ 5.97 weight% in molten LiCl-KCl at 450°C can sustain a rapid leaching and recovery process. Overall, MSE is a simple, rapid, and environmental-benign method to recover Pb-based PSCs, eliminating the Pb contamination and closing the iodine cycle. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Category: chlorides-buliding-blocks).

Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Category: chlorides-buliding-blocks

Recovery of Lithium Carbonate from Dilute Li-Rich Brine via Homogenous and Heterogeneous Precipitation was written by Battaglia, Giuseppe;Berkemeyer, Leon;Cipollina, Andrea;Cortina, Jose Luis;Fernandez de Labastida, Marc;Lopez Rodriguez, Julio;Winter, Daniel. And the article was included in Industrial & Engineering Chemistry Research in 2022.Computed Properties of ClLi The following contents are mentioned in the article:

An extensive exptl. campaign on Li recovery from relatively dilute LiCl solutions (i.e., Li⁺ ~4000 ppm) is presented to identify the best operating conditions for a Li₂CO₃ crystallization unit. Lithium is currently mainly produced via solar evaporation, purification, and precipitation from highly concentrated Li brines located in a few world areas. The process requires large surfaces and long times (18-24 mo) to concentrate Li⁺ up to 20,000 ppm. The present work investigates two separation routes to extract Li⁺ from synthetic solutions, mimicking those obtained from low-content Li⁺ sources through selective Li⁺ separation and further concentration steps: (i) addition of Na₂CO₃ solution and (ii) addition of NaOH solution + CO₂ insufflation. A Li recovery up to 80% and purities up to 99% at 80°C and with high-ionic strength solutions was achieved employing NaOH solution + CO₂ insufflation and an ethanol washing step. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Computed Properties of ClLi).

Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water.

The reaction of [Hg(mbm)₂] (mbm = o-SC₆H₄CONH₂) with Na₂S releases Na[mbm] which reacts with Pd(II) salts to give [Pd(mbm)₂]. While its precise mol. structure is unknown, [Pd(mbm)₂] reacts with two equivalent of PPh₃ to afford trans-[Pd(κ¹-mbm)₂(PPh₃)₂] in which the mbm ligands bind through a sulfur atom. With dppf, a similar complex, [Pd(κ¹-mbm)₂(κ²-dppf)], is formulated with the mbm ligands being forced into a relative cis orientation. With dppm, a mixture of mononuclear [Pd(κ¹-mbm)₂(dppm)] and binuclear [Pd(κ¹-mbm)₂(μ-dppm)]₂ results. The new complexes have been characterized by IR, ¹H and ³¹P{¹H} NMR, molar conductivity and elemental anal., and in addition, the mol. structure of trans-[Pd(κ²-mbm)₂(PPh₃)₂] was confirmed by x-ray diffraction.

And the article was included in European Journal of Inorganic Chemistry in 2021.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Reaction of a phosphine-decorated benzenedithiol (pbdtH₂) with coinage metal salts furnished polynuclear complexes [M₂(pbdtH)₂] (M = Au^I) or [cat][M₅(pbdt)₃] (cat = unipos. cation, M = Ag^I, Cu^I), which were characterized by anal. and spectroscopic techniques and single-crystal x-ray diffraction studies. Also, a double salt with an anion [Ag₅(pbdt)₃(PPh₃)]^– that proved unstable in solution was characterized crystallog. The spectroscopic and crystallog. data revealed that the Cu(I) and Ag(I) complexes exhibit, despite their like stoichiometric composition, isomeric mol. structures. The observed disparities were reproduced by DFT studies. The dinuclear Au(I) complex was found to undergo air-oxidation to furnish a mixed-valent complex [(Au^III)₂(Au^I)₂(pbdt)₄]. The copper(I) – but not the isomeric silver(I) complexes – showed luminescence in the solid state.

An ionic liquid Aliquat 336 was for the first time analyzed for its adsorption and corrosion inhibition behavior for carbon steel surface in 0.5 M H₂SO₄. The inhibition performance was studied using gravimetric and electrochem. techniques supported by surface anal. measurements. The inhibitor exerted an efficiency of 96.53% at 12×10^-6 M. Significant improvement was achieved with iodide ions, which at 3.01×10^-4 M, produced a remarkable rise in the efficiency to 99.03%. The adsorption of the inhibitor on the metallic surface followed the Langmuir isotherm at 298 K in the concentration range of 2.47 to 12.37×10^-6 M. Polarization studies indicated a mixed-mode of inhibitor action with the cathodic predominance. The SEM studies showed a smooth metal surface in contact with the inhibitor, and a representative decrease in surface roughness was observed by AFM studies. Monte Carlo simulations showed inhibitor adsorption in a flat orientation on the metal surface with high adsorption energy.

Enhanced stability and water solubilizing capacity of water-in-oil microemulsions based on protic ionic liquids was written by Singh, Akhil Pratap;Kundu, Kaushik;Singh, Vikram;Gardas, Ramesh L.;Senapati, Sanjib. And the article was included in Physical Chemistry Chemical Physics in 2017.Reference of 122-18-9 The following contents are mentioned in the article:

To increase the stability and water uptake capacity of water-in-oil (W/O) microemulsions, the physicochem. behavior of a series of W/O microemulsion-based protic ionic liquids was assessed, wherein solute amounts of biocompatible tetramethylguanidinium cation-based ionic liquids (IL) were added to the W/O microemulsion aqueous phases. Fourier transform IR (FTIR) spectroscopy and time-resolved fluorescence measurements showed increased water uptake by these reverse micellar droplets vs. conventional W/O microemulsions with similar compositions Dynamic light scattering and differential scanning calorimetry measurements suggested greater droplet thermal stability in the presence of IL. NMR and FTIR measurements and ab-initio calculations explained these results by showing an extended H bonding network between interfacial water and protic IL ions, and strong electrostatic associations between surfactant head-groups and IL anions. Results provide potential applications of protic ionic liquids in emulsion and microemulsion science and technol.

On the origins of conductive pulse sensing inside a nanopore was written by Lastra, Lauren S.;Bandara, Y. M. Nuwan D. Y.;Nguyen, Michelle;Farajpour, Nasim;Freedman, Kevin J.. And the article was included in Nature Communications in 2022.Application In Synthesis of Lithium chloride The following contents are mentioned in the article:

Nanopore sensing is nearly synonymous with resistive pulse sensing due to the characteristic occlusion of ions during pore occupancy, particularly at high salt concentrations Contrarily, conductive pulses are observed under low salt conditions wherein electroosmotic flow is significant. Most literature reports counterions as the dominant mechanism of conductive events (a mol.-centric theory). However, the counterion theory does not fit well with conductive events occurring via net neutral-charged protein translocation, prompting further investigation into translocation mechanics. Herein, we demonstrate theory and experiments underpinning the translocation mechanism (i.e., electroosmosis or electrophoresis), pulse direction (i.e., conductive or resistive) and shape (e.g., monophasic or biphasic) through fine control of chem., phys., and electronic parameters. Results from these studies predict strong electroosmosis plays a role in driving DNA events and generating conductive events due to polarization effects (i.e., a pore-centric theory). This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Application In Synthesis of Lithium chloride).

Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.

Targeting the protein-protein interaction (PPI) between nuclear factor erythroid 2-related factor 2 (Nrf2) and Kelch-like ECH-associated protein 1 (Keap1) is a potential therapeutic strategy to control diseases involving oxidative stress. Here, six classes of known small-mol. Keap1-Nrf2 PPI inhibitors were dissected into 77 fragments in a fragment-based deconstruction reconstruction (FBDR) study and tested in four orthogonal assays. This gave 17 fragment hits of which six were shown by X-ray crystallog. to bind in the Keap1 Kelch binding pocket. Two hits were merged into pyrazole I with a 220-380-fold stronger affinity (K_i = 16μM) relative to the parent fragments. Systematic optimization resulted in several novel analogs with K_i values of 0.04-0.5μM, binding modes determined by X-ray crystallog., and enhanced microsomal stability. This demonstrates how FBDR can be used to find new fragment hits, elucidate important ligand-protein interactions, and identify new potent inhibitors of the Keap1-Nrf2 PPI.

Supramolecular hydrogelation via host-guest anion recognition: Lamellar hydrogel materials for the release of cationic cargo was written by Kokan, Zoran;Duskova-Smrckova, Miroslava;Sindelar, Vladimir. And the article was included in Chem in 2021.COA of Formula: C4H12ClN The following contents are mentioned in the article:

Hydrogelation triggered by host-guest anion recognition is difficult to achieve due to the challenging anion recognition in water and de novo gelator design. Herein, we report such a hydrogel system, based on bambus[6]uril anion receptor, BU. Albeit not a gelator per se, BU formed hydrogels selectively in the presence of iodides or perchlorates. Anion recognition by BU governed the hydrogelation, indicated by the NMR, ATR-IR, and single-crystal X-ray. Gelation mechanism and lamellar nature of the network structure were elucidated by SAXS, cryoSEM, and holotomog. methods. Rheol. characterization revealed the hydrogels were stable and relatively strong. In physiol. saline solutions, the hydrogels released cationic cargo by cation metathesis, leading to a gel-to-gel transformation. Choline derivatives, as model drugs, exhibited slow release from the hydrogels. Our simple hydrogel system may inspire the design of smart materials based on host-guest anion recognition, where the release or sequestration of specific charged species are desirable.

The realization of efficient and fully controllable synthesis of single atom catalysts is an exciting frontier, yet still challenging in the modern catalysis field. Here we describe a straightforward high-temperature quenching approach to precisely construct isolated palladium atoms supported over cubic indium oxide, with individual palladium atoms coordinated with four neighboring oxygen atoms. This palladium catalyst achieves exceptional catalytic efficiency in the selective hydrogenation of nitrobenzene to aniline, with more than 99% chemoselectivity under almost 100% conversion. Moreover, it delivers excellent recyclability, anti-CO poisoning ability, storage stability, and substrate tolerance. DFT calculations further reveal that the high catalytic activity stems from the optimized electronic structure and the charge states of palladium atoms in the defect-containing indium oxide. Our findings provide an effective approach to engineering single atom catalysts at the at. level and open the door to a wide variety of catalytic reactions.
