Author is Talukdar, Biva; Kuo, Tung-Chun; Sneed, Brian T.; Lyu, Lian-Ming; Lin, Hung-Min; Chuang, Yu-Chun; Cheng, Mu-Jeng; Kuo, Chun-Hong.

The global ammonia yield is critical to the fertilizer industry as the global food demand is highly dependent on it, whereas, NH3 is also a key chem. for pharmaceutical, textile, plastic, explosive, and dye-making industries. At present, the demand for NH3 is fulfilled by the Haber-Bosch method, which consumes 1-3% of global energy and causes 0.5-1% CO2 emission every year. To reduce emissions and improve energy efficiency, the electrochem. nitrogen gas reduction reaction (N2RR) has received much attention and support after the funding announcement by the U.S. Department of Energy. In this work, we have created hollow CuAu nanoboxes with Cu-rich inner walls to improve the NH3 Faradaic efficiency in N2RR. These beveled nanoboxes are produced in different degrees of corner and edge etching, which produces both polyhedral and concave structures. In N2RR, the binary CuAu nanoboxes enhanced NH3 production compared to individual Au and Cu nanocubes. The results of DFT calculations suggest the Cu-rich inner walls in the hollow beveled CuAu nanoboxes play a major role in their performance by reducing the free energy ΔG*NNH for the potential-determining step to form *NNH (* + N2(g) + H+ + e- → *NNH). Meanwhile, the results in 10-cycle and solar-illuminated N2RR indicate the beveled CuAu nanoboxes are not only robust electrocatalysts but show promise in photocatalysis as well.

Keywords: cadmium selenide zinc sulfide quantum dot Langmuir monolayer aggregation. Let’s learn more about this compound (cas:78-50-2).

The process of formation of a Langmuir-Schaefer (LS) matrix based on a mixed monolayer of arachidic acid (AA) and 8 nm CdSe/CdS/ZnS quantum dots (QDs) stabilized by mols. of trioctylphosphine oxide (TOPO) was investigated. The change in the morphol., monolayer compressibility, and area per elementary cell of the created mixed monolayers, depending on the ratio of the components, was studied. It is shown that the change in the morphol. of Langmuir-Blodgett (LB) monolayers begins to occur at a ratio between the number of QDs and AA mols. of 1:24. Dendrimeric structures with a thickness of the order of 30-40 nm appear in the mixed monolayer when LB film deposition was carried out above the collapse surface pressure of a Langmuir film from only TOPO-covered QDs. Information on the dependence of the morphol. of such structures on the molar ratio of the components is necessary for the production of ordered 2D nanostructures containing 0D and 1D objects with quantum bonds. Such nanostructures can be used in nanoelectronic and optoelectronic devices as a sensitive sensor element. The obtained results would be relevant for any type of spherical shape nanoparticles.

Compound: Tri-n-octylphosphine Oxide( cas:78-50-2 ) is researched.Safety of Tri-n-octylphosphine Oxide.Singh, Sajan; Horechyy, Andriy; Yadav, Sushma; Formanek, Petr; Hubner, Rene; Srivastava, Rajiv K.; Sapra, Sameer; Fery, Andreas; Nandan, Bhanu published the article 《Nanoparticle-Stabilized Perforated Lamellar Morphology in Block Copolymer/Quantum Dot Hybrids》 about this compound( cas:78-50-2 ) in Macromolecules (Washington, DC, United States). Keywords: nanoparticle stabilized perforated lamellar morphol copolymer quantum dot hybrid. Let’s learn more about this compound (cas:78-50-2).

We report on the surprising observation of a unique perforated lamellar (PL) morphol. in a mixture of an asym. polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) block copolymer and CdSe-CdS quantum dots (QDs). The PL morphol. formed by the PS-b-P4VP/CdSe-CdS composites consisted of alternating layers of PS and P4VP, where the layer formed by the minority PS block contained cylindrical perforations of the majority P4VP block. Most interestingly, the CdSe-CdS QDs were localized exclusively in the P4VP perforations. The swelling of the bulk samples in a P4VP selective solvent also allowed the isolation of the perforated PS nanosheets, with QDs localized in the perforations, which further provided strong evidence for the formation of the unique PL morphol. The observed PL morphol. was, plausibly, energetically stabilized because of the localization of QDs within the P4VP perforations, which allowed for the conformational entropy minimization of the majority P4VP block. The present work reveals possibilities for the discovery of novel hierarchical structures in block copolymer/nanoparticle composite systems and also provides new opportunities for the application of such materials in nanotechnol.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 78-50-2, is researched, Molecular C24H51OP, about Influence of polystyrene ligand length on the spatial arrangement of quantum dots within PS-b-PEO micelles, the main research direction is polystyrene length cadmium sulfide selenide quantum dot spatial arrangement; ethylene oxide styrene block polymer micelle optical property.Related Products of 78-50-2.

The spatial arrangement of functional inorganic nanoparticles within polymer micelles is essential to the nanocomposite performances. Polystyrene (PS) of different lengths (PS24, PS91 and PS163) are grafted onto the surface of fluorescent CdSe/CdS core/shell quantum dots (QDs) through ligand exchange procedure, and their grafting d. decreases from 2.80 to 0.54, 0.18 chains/nm2 with increase of PS ligand length. Under two competing effects, i.e. wettability between QDs and block copolymer PS120-b-PEO318 and the attraction between QDs, the precise location of PS-capped QDs inside the co-assemblies can be regulated by the length of PS ligands. The low grafting d. of PS163 on the QD surface cannot overcome the van der Waals and hydrophobic attraction between QDs and cause the local aggregation of QDs within the co-assemblies. On the contrary, short PS24 ligands with high grafting d. can avoid QD aggregation, but exhibit poor wettability with copolymer, which confines the QDs in the central portion of the core of co-assemblies. PS91 ligands with medium grafting d. have good wettability with block copolymer and facilitate the homogeneous distribution of QDs inside the cores of co-assemblies. Furthermore, the influence of stirring time and water addition rate on the structure of co-assemblies is also investigated.

Compound: Tri-n-octylphosphine Oxide, is researched, Molecular C24H51OP, CAS is 78-50-2, about Perovskite Light-Emitting Diodes with External Quantum Efficiency Exceeding 22% via Small-Molecule Passivation. Author is Chu, Zema; Ye, Qiufeng; Zhao, Yang; Ma, Fei; Yin, Zhigang; Zhang, Xingwang; You, Jingbi.

Perovskite light-emitting diodes (PeLEDs) are considered as particularly attractive candidates for high-quality lighting and displays, due to possessing the features of wide gamut and real color expression. However, most PeLEDs are made from polycrystalline perovskite films that contain a high concentration of defects, including point and extended imperfections. Reducing and mitigating non-radiative recombination defects in perovskite materials are still crucial prerequisites for achieving high performance in light-emitting applications. Here, ethoxylated trimethylolpropane triacrylate (ETPTA) is introduced as a functional additive dissolved in antisolvent to passivate surface and bulk defects during the spinning process. The ETPTA can effectively decrease the charge trapping states by passivation and/or suppression of defects. Eventually, the perovskite films that are sufficiently passivated by ETPTA make the devices achieve a maximum external quantum efficiency (EQE) of 22.49%. To our knowledge, these are the most efficient green PeLEDs up to now. In addition, a threefold increase in the T50 operational time of the devices was observed, compared to control samples. These findings provide a simple and effective strategy to make highly efficient perovskite polycrystalline films and their optoelectronics devices.

Bis(4-methylpiperidine-1-carbodithioato)-lead(II) and bis(4-benzylpiperidine-1-carbodithioato)-lead(II) were prepared and their mol. structures elucidated using single crystal X-ray crystallog. and spectroscopic techniques. The compounds were used as precursors for the preparation of lead sulfide nano photocatalysts for the degradation of rhodamine B. The single crystal structures of the lead(II) dithiocarbamate complexes show mononuclear lead(II) compounds in which each lead(II) ion coordinates two dithiocarbamato anions in a distorted tetrahedral geometry. The compounds were thermolyzed at 180 °C in hexadecylamine (HDA), octadecylamine (ODA), and trioctylphosphine oxide (TOPO) to prepare HDA, ODA, and TOPO capped lead sulfide (PbS) nanoparticles. Powder X-ray diffraction (pXRD) patterns of the lead sulfide nanoparticles were indexed to the rock cubic salt crystalline phase of lead sulfide. The lead sulfide nanoparticles were used as photocatalysts for the degradation of rhodamine B with ODA-PbS1 achieving photodegradation efficiency of 45.28% after 360 min. The photostability and reusability studies of the as-prepared PbS nanoparticles were studied in four consecutive cycles, showing that the percentage degradation efficiency decreased slightly by about 0.51-1.93%. The results show that the as-prepared PbS nanoparticles are relatively photostable with a slight loss of photodegradation activities as the reusability cycles progress.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures.

Synthesis of Cu-In-S (CIS) nanoparticles by hot injection method using a mixed solution of Cu(acac), In(acac) and DDT in solvents OAm and trioctylphosphine oxide (TOPO), was carried in nitrogen atm. Phase and crystallog. structure evolution were evaluated by extracting samples at intermediate synthesis stages and was characterized by X-ray diffraction and transmission electron microscopy. Ex-situ observation of phases indicated the formation and growth of Cu2S at the earlier stages. With further increase in temperature, CIS formed with the diffusion of In3+ ion. Wurtzite CIS nanoparticles preferentially grew along a length (from ∼42 to 62 nm) while the width nearly remained constant to about ∼32 nm. The preferential growth took place along [0002] while the particle width was oriented along [1010], which resulted in nearly oval-shaped nanoparticles. FTIR spectra recorded at different stages of synthesis (50-310°C) pointed towards the ligand exchange mechanism after the addition of sulfur source at (160°C).

Highly mesoporous SiO2-encapsulated NixPy crystals, where (x, y) = (5, 4), (2, 1), and (12, 5), were successfully synthesized by adopting a thermolytic method using oleylamine (OAm), trioctylphosphine (TOP), and trioctylphosphine oxide (TOPO). The Ni5P4@SiO2 system shows the highest reported activity for the selective hydrogenation of SO2 toward H2S at 320°C (96% conversion of SO2 and 99% selectivity to H2S), which was superior to the activity of the com. CoMoS@Al2O3 catalyst (64% conversion of SO2 and 71% selectivity to H2S at 320°C). The morphol. of the Ni5P4 crystal was finely tuned via adjustment of the synthesis parameters receiving a wide spectrum of morphologies (hollow, macroporous-network, and SiO2-confined ultrafine clusters). Intrinsic characteristics of the materials were studied by X-ray diffraction, high-resolution transmission electron microscopy/scanning transmission electron microscopy-high-angle annular dark-field imaging, energy-dispersive X-ray spectroscopy, the Brunauer-Emmett-Teller method, H2 temperature-programmed reduction, XPS, and exptl. and calculated 31P magic-angle spinning solid-state NMR toward establishing the structure-performance correlation for the reaction of interest.
