Author is Lee, Da Won; Woo, Ho Young; Lee, Dong Hyun David; Jung, Myung-Chul; Lee, Donguk; Lee, MinJi; Kim, Jong Bae; Chae, Ji Yeon; Han, Myung Joon; Paik, Taejong.

In this paper, the N,N-dimethylformamide (DMF)-assisted shape evolution of highly uniform and shape-pure copper nanocrystals (Cu NCs) is presented for the first time. Colloidal Cu NCs are synthesized via the disproportionation reaction of copper (I) bromide in the presence of a non-polar solvent mixture It is observed that the shape of Cu NCs is systematically controlled by the addition of different amounts of DMF to the reaction mixture in high-temperature reaction conditions while maintaining a high size uniformity and shape purity. With increasing amount of DMF in the reaction mixture, the morphol. of the Cu NCs change from a cube enclosed by six {100} facets, to a sphere with mixed surface facets, and finally, to an octahedron enclosed by eight {111} facets. The origin of this shape evolution is understood via first-principles d. functional theory calculations, which allows the study of the change in the relative surface stability according to surface-coordinating adsorbates. Further, the shape-dependent plasmonic properties are systematically investigated with highly uniform and ligand-exchanged colloidal Cu NCs dispersed in acetonitrile. Finally, the facet-dependent electrocatalytic activities of the shape-controlled Cu NCs are investigated to reveal the activities of the highly uniform and shape-pure Cu NCs in the methanol oxidation reaction.

Broadening of multiexciton emission from colloidal quantum dots (QDs) at room temperature is important for their use in high-power applications, but an in-depth characterization has not been possible until now. We present and apply a novel spectroscopic method to quantify the biexciton line width and biexciton binding energy of single CdSe/CdS/ZnS colloidal QDs at room temperature In our method, which we term “”cascade spectroscopy””, we select emission events from the biexciton cascade and reconstruct their spectrum. The biexciton has an average emission line width of 86 meV on the single-QD scale, similar to that of the exciton. Variations in the biexciton repulsion (Eb = 4.0 ± 3.1 meV; mean ± standard deviation of 15 QDs) are correlated with but are more narrowly distributed than variations in the exciton energy (10.0 meV standard deviation). Using a simple quantum-mech. model, we conclude that inhomogeneous broadening in our sample is primarily due to variations in the CdS shell thickness.

Author is Geuchies, Jaco J.; Brynjarsson, Baldur; Grimaldi, Gianluca; Gudjonsdottir, Solrun; van der Stam, Ward; Evers, Wiel H.; Houtepen, Arjan J..

Solution-processed quantum dot (QD) lasers are one of the holy grails of nanoscience. They are not yet commercialized because the lasing threshold is too high: one needs >1 exciton per QD, which is difficult to achieve because of fast nonradiative Auger recombination. The threshold can, however, be reduced by electronic doping of the QDs, which decreases the absorption near the band-edge, such that the stimulated emission (SE) can easily outcompete absorption. Here, by electrochem. doping films of CdSe/CdS/ZnS QDs, the authors achieve quant. control over the gain threshold. The authors obtain stable and reversible doping of more than two electrons per QD. The authors quantify the gain threshold and the charge carrier dynamics using ultrafast spectroelectrochem. and achieve quant. agreement between experiments and theory, including a vanishingly low gain threshold for doubly doped QDs. Over a range of wavelengths with appreciable gain coefficients, the gain thresholds reach record-low values of ~1 × 10-5 excitons per QD. These results demonstrate a high level of control over the gain threshold in doped QD solids, opening a new route for the creation of cheap, solution-processable, low-threshold QD lasers.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Solvent-Controlled Intermolecular Proton-Transfer Follows an Irreversible Eigen-Weller Model from fs to ns, published in 2021-12-31, which mentions a compound: 78-50-2, mainly applied to solvent controlled intermol proton transfer, Name: Tri-n-octylphosphine Oxide.

Intermol. Proton Transfer (PT) dynamics can be best studied by optical spectroscopy, which can cover the vast timescale spanned by the process. PT in a hydrogen bonding complex between a pyranine-based photoacid and a trialkyl-phosphine oxide is addressed. The photoreaction is traced with the help of femtosecond transient absorption and picosecond-resolved fluorescence. Characteristic kinetics and spectra of the intervening species are isolated by global anal. and spectral decomposition of time-resolved fluorescence. It is found that the shared proton shifts towards the phosphine site upon photoexcitation in acetonitrile. The process occurs on the sub-picosecond timescale, essentially, under solvent control. Despite the ultrafast rate, an equilibrium between the complex and the hydrogen-bonded ion pair (HBIP) is established. Further reaction steps are delayed to the nanosecond timescale, where formation of the excited deprotonated form is observed The far-reaching consistency between the various methods supports an irreversible Eigen-Weller mechanism in the excited state.

Author is Asadollahzadeh, Mehdi; Torkaman, Rezvan; Torab-Mostaedi, Meisam; Hemmati, Alireza.

One of the high-tech industries is glass polishing, which is associated with the release of large volumes of wastewater, a rich source of rare-earth metals, especially cerium. In this study, cerium ion recovery from glass polishing powder waste using green solvents for extraction was investigated. Reaction time, temperature, organic to aqueous ratio, extractant concentrations, and the synergistic effects of imidazolium ionic liquids and trioctylphosphine oxide and tributylphosphate as extractants were optimized. The co-extraction of lanthanum, a significant problem in extracting cerium, was reduced by enhancement of their separation factor (∼ 17). The cerium-bearing organic solvent was stripped with 0.5 mol/L HNO3 to attain a recovery of cerium by 99.98%. The ionic liquids are useful in the extraction process, enabling higher yields of cerium and reducing the consumption of acids in the stripping stage.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Tri-n-octylphosphine Oxide, is researched, Molecular C24H51OP, CAS is 78-50-2, about Fast Lifetime Blinking in Compact CdSe/CdS Core/Shell Quantum Dots, the main research direction is fast lifetime blinking compact CdSe CdS core shell QD.Application In Synthesis of Tri-n-octylphosphine Oxide.

Lifetime blinking is another type of fluorescence fluctuation in single colloidal quantum dots (QDs) apart from the extensively studied intensity blinking. It is a phenomenon of fluctuations in the fluorescence lifetime of a single QD over time while its fluorescence intensity is relatively unaffected. So far, lifetime blinking has only been reported in a few QD systems, such as “”giant”” (i.e., thick-shell) CdSe/CdS core/shell QDs. It remains unclear whether this phenomenon is universal among QDs. In this work, we use statistical methods to demonstrate that the lifetime blinking state, although short-lived, also exists in compact CdSe/CdS core/shell QDs in which nonradiative processes are efficient and lead to intensity blinking when activated. We propose that lifetime blinking happens when a neg. trion forms in the core of a QD after photoexcitation while nonradiative processes are not activated. However, the easy accessibility to efficient nonradiative processes results in the short durations of lifetime blinking events in this type of QDs.

This research aims to predict succinic acid concentration in the external phase during the emulsion liquid membrane process by using artificial neural networks along with a popular alternative method: k-nearest neighbor technique. The solute concentration values can be predicted by the proposed method without performing a great number of emulsion liquid membrane experiments Several computer simulations were performed to demonstrate the success of the system. Simulation results showed that the estimated solute concentration values are very close to the achieved exptl. results. The optimal conditions for emulsion liquid membrane were found to be: solvent kerosene, TOPO concentration (1%weight/weight), Amberlite LA-2 concentration (4%weight/weight), surfactant concentration (5%weight/weight), Na2CO3 concentration (5%w/v), modifier (decanol) concentration (2%weight/weight), mixing speed 300 rpm.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

Demand for scandium (Sc) has been increasing in recent years. However, there are almost no ores containing Sc, and the supply is insufficient because the separation and recovery of Sc as a byproduct from oxide minerals such as ilmenite ore, bauxite, and laterite are difficult. In this study, extraction and separation of Sc3+ from acidic chloride or acidic nitrate solutions containing transition metals such as Fe3+, Co2+, Ni2+, Zn2+, and Pd2+ were studied using N-lauroylsarcosine (NLS) and tri-n-octylphosphine oxide (TOPO), which together create a “”deep eutectic solvent”” (DES). Owing to the resp. selectivity of NLS and TOPO by different extractive interactions between metal ions and the two extractants in toluene, Sc3+ was effectively and selectively separated even from Fe3+ in the aqueous ammonium nitrate solution, the mutual separation of which is difficult with NLS alone. The mutual separation of Sc3+ and Fe3+ in acidic chloride solution is in general very difficult, while the mutual separation of these metals from acidic nitrate solution is successful. This is due to either anions forming complexes with Sc3+ in the aqueous phase (chloride) or not (nitrate). The potential use of the combination of the NLS with TOPO for selective recovery of Sc3+ from Fe3+ in a refining process is demonstrated.

Author is Rajendaren, Vikneswary; Saufi, Syed M.; Zahari, M. A. K. M.; Mohammad, Abdul Wahab.

Glutamic acid (GA) is an amino acid which is usually appear in the zwitterionic form in solutions At present, cation and anion exchange carriers are widely use to extract this amino acids. However, the carriers only function either at high pH or low pH. Although, the pH can be adjusted by adding certain chem. to reach acidic or basic region, but it may lead to addnl. byproducts formation and affect the extraction process. In the current study, supported liquid membrane (SLM) was used to extract the zwitterionic form of GA from the aqueous solution without any pH adjustment. In the SLM process, the determination of the best carrier in liquid membrane formulation is important for achieving high extraction of GA. Hence, different types of carriers such as trioctylamine (TOA), tridodecylamine (TDA), tri-n-octyl phosphine oxide (TOPO), mixture of 50% TOA and 50% TDA, aliquat 336 and di-2-ethylhexyl phosphoric acid (D2EHPA) in 2-ethyl-1-hexanol were investigated. The polyethersulfone (PES) membrane with and without graphene membrane supports were prepared, characterized and used as the support in the SLM. The incorporation of graphene in PES membrane had increased the surface contact angle and tensile stress from 80.96 ± 1.92° to 97.8 ± 1.46° and 650.684 kPa to 1079.59 kPa, resp. Aliquat 336 was identified as the best carrier with 93% of GA extraction
