Catalytic Reductions Without External Hydrogen Gas: Broad Scope Hydrogenations with Tetrahydroxydiboron and a Tertiary Amine

Facile reduction of aryl halides with a combination of 5% Pd/C, B-2(OH)(4), and 4-methylmorpholine is reported. Aryl bromides, iodides, and chlorides were efficiently reduced. Aryl dihalides containing two different halogen atoms underwent selective reduction: I over Br and Cl, and Br over Cl. Beyond these, aryl triflates were efficiently reduced. This combination was broadly general, effectuating reductions of benzylic halides and ethers, alkenes, alkynes, aldehydes, and azides, as well as for N-Cbz deprotection. A cyano group was unaffected, but a nitro group and a ketone underwent reduction to a low extent. When B-2(OD)(4) was used for aryl halide reduction, a significant amount of deuteriation occurred. However, H atom incorporation competed and increased in slower reactions. 4-Methylmorpholine was identified as a possible source of H atoms in this, but a combination of only 4-methylmorpholine and Pd/C did not result in reduction. Hydrogen gas has been observed to form with this reagent combination. Experiments aimed at understanding the chemistry led to the proposal of a plausible mechanism and to the identification of N,N-bis(methyl-d(3))pyridin-4-amine (DMAP-d(6)) and B-2(OD)(4) as an effective combination for full aromatic deuteriation.

Self-healing thiol-ene networks based on cyclodextrin-adamantane host-guest interactions

The reactions of beta-cyclodextrin, pentaerythritol propoxylate and 1-adamantanecarboxylic acid with allyl bromide in the presence of basic salts generated their allylated products (ACD, APEP and AAd, respectively). The thiol-ene photopolymerizations of these allylated compounds and pentaerythritol tetrakis(3-mercaptopropionate) (S4P) produced thiol-ene network films (ACD-S4P, ACD-APEP-S4P, ACD-AAd-S4P, APEP-AAd-S4P and ACD-APEP-AAd-S4P). The FT-IR and gel fraction measurements of the photo-cured films revealed that almost all the thiol and allyl groups were consumed, and polymer networks were certainly formed. Glass transition temperatures (0.5 and 0.3 degrees C) of ACD-S4P and ACD-AAd-S4P were higher than those (-9 to -15 degrees C) of other films incorporating APEP. The tensile strength and modulus of ACD-S4P were much higher than those of the films incorporating APEP or AAd. Only the films incorporating both ACD and AAd possessed the selfhealing property. ACD-AAd-S4P showed a higher tensile strength and modulus than ACD-APEP-AAd-S4P did. ACD-AAd-S4P was healed twice at 80 degrees C and only once at room temperature. ACD-APEP-AAd-S4P was healed only once at 80 degrees C. The maximum healing efficiency was 85% for tensile modulus of ACD-AAd-S4P.

Efficient and Stable Low-Bandgap Perovskite Solar Cells Enabled by a CsPbBr3-Cluster Assisted Bottom-up Crystallization Approach

Recently, low-bandgap formamidinium lead iodide FAPbI(3)-based perovskites are of particular interest for high-performance perovskite solar cells (PSCs) due to their broad spectral response and high photocurrent output. However, to inhibit the spontaneous alpha-to-delta phase transition, 15-17% (molar ratio) of bromide and cesium or methylammonium incorporated into the FAPbI(3) are indispensable to achieve efficient PSCs. In return, the high bromide content will increase bandgap and narrow the spectral response region. If simply reducing the bromide content, the corresponding PSCs exhibit inferior operational stability due to alpha-to-delta phase transition, interface degradation, and halide migration. Herein, we report a CsPbBr3-cluster assisted vertically bottom-up crystallization approach to fabricate low-bromide (1% similar to 6%), alpha-phase pure, and MA-free FAPbI(3)-based PSCs. The clusters, in the size of several nanometers, could act as nuclei to facilitate vertical growth of high quality alpha-FAPbI(3) perovskite crystals. Moreover, these clusters can show further intake by perovskite after thermal annealing, which improves the phase homogeneity of the as-prepared perovskite films. As a result, the corresponding mesoporous PSCs deliver a champion efficiency of 21.78% with photoresponse extended to 830 nm. Moreover, these devices show remarkably improved operational stability, retaining similar to 82% of the initial efficiency after 1,000 h of maximum power point tracking under 1 sun condition.

Self-assembled non-volatile micro memory arrays of molecular ferroelectrics

Numerous molecular ferroelectrics having excellent properties even comparable to inorganic ones, which usually contain heavy or toxic metals, have been developed recently. Hopefully, they can be used as substitutes for the well-known organic ferroelectric polymers (P(VDF-TrFE)) with huge coercive fields and poor spontaneous polarization for various applications. However, the bottleneck for practical applications, i.e., the preparation of high-quality thin films and high resolution device arrays with a desired crystallographic orientation for memory switching, still remains. In this study, large-area micro device arrays of molecular ferroelectrics with highly-crystalline or even single-crystalline films are intentionally self-assembled on electrodes or within electrode gaps using a solution processing technique, including the molecular ferroelectrics for which it is usually difficult to make thin films. The as-grown air-stable memory micro arrays with an optimum crystallographic orientation can exhibit excellent non-volatile memory performance with a smaller operation voltage of <5 V. These attributes can pave the way for molecular ferroelectrics to become a promising candidate for applications including flexible memories and circuits. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Supraamphiphilic Systems Based on Metallosurfactant and Calix[4]resorcinol: Self-Assembly and Drug Delivery Potential

Metallic amphiphiles are used as building blocks in the construction of nanoscale superstructures, where the hydrophobic effects induce the self-assembly of the nanopartides of interest. However, the influence of synergizing multiple chemical interactions on an effective design of these structures mostly remains an open question. In this regard, supraamphiphilic systems based on flexible surfactant molecules and rigid macrocycles are being actively developed, but there are few works on the interaction between metallosurfactants and macrocydes. In the present work, the self-assembly and biological properties of a metallosurfactant with calixarene were studied for the first time. The metallosurfactant, a complex between lanthanum nitrate and two 4-aza-1-hexadecylazoniabicyclo[2.2.2]octane bromide units, and calix[4]resorcinol containing sulfonate groups on the upper rim were used to form a novel supraamphiphilic composition. The system formed was studied using a variety of physicochemical methods, including spectrophotometry, NMR, XRF, and dynamic and electrophoretic light scattering. It was found that the most optimal tetraanionic calix[4]resorcinol to dicationic metallosurfactant molar ratio, leading to mixed aggregation upon ion pair complexation, is 2:3. The mixed aggregates formed in the pentamolar concentration range were able to encapsulate hydrophilic substrates, including the anticancer drug cisplatin, the pure form of which is more cytotoxic toward healthy cells than toward diseased cells. Interestingly, the drug loaded into the macrocycle-metallosurfactant particles was less cytotoxic to a healthy Chang liver cell line and more cytotoxic to tumor M-HeLa cells. This selectivity depends on the amount of cisplatin added. The more drug is added to the macrocycle-metallosurfactant composition, the greater the biological activity against cancer cells. Taking into account that the appearance of resistance of cancer cells to drugs, especially to cisplatin, is one of the most important problems in treatment, the results of this work envisage the potential application of a mixed macrocycle-metallosurfactant system for the design of therapeutic cisplatin compositions.

Density functional study of spectroscopy, electronic structure, linear and nonlinear optical properties of L-proline lithium chloride and L-proline lithium bromide monohydrate: For laser applications

Using density functional theory (DFT), a systematic study of structure, bonding, vibration, excitation energies and non-linear optical properties has been carried out for noncentrosymmetric L-proline lithium chloride monohydrate and L-proline lithium bromide monohydrate for the xrst time. The calculated vibrational frequencies and the S-0 -> S-1 transition energy were compared with the earlier reported experimental results and found in good agreement. HOMO-LUMO energy gap was calculated by CIS, B3LYP and CISD using 6-31G(d,p), 3-21G, 6-31++G respectively and the obtained results are compared. For the calculation of excitation energies we used time dependent DFT (TDDFT). Both the molecules show the considerably lower dipole moment in excited state in comparison with the ground state. Mulliken charge and molecular electrostatic potential were studied. The xrst order hyperpolarizability for LPLCM and LPLBM are 2.15675 x 10(-30) esu and 3.78984 x 10(-30) esu respectively which are 5 and 10 times higher than prototype urea (0.3728 x 10(-30) esu) molecule. The global chemical reactivity descriptors were also calculated. The calculated results of polarizability, xrst and second hyperpolarizability conxrm that these molecules are good non-linear optical materials and can be used for laser device fabrications.

ROS Plays a Role in the Neonatal Rat Intestinal Barrier Damages Induced by Hyperoxia

Background. Hyperoxia treats a subset of critical neonatal illnesses but induces intestinal damage in neonatal pups. In this process, the intestinal flora and mucosal epithelium might be altered by hyperoxia. So the changes of the intestinal flora and mucosal epithelium were studied. Methods. Neonatal rats were randomized into the model group that was exposed to hyperoxia and the control group that was maintained under normoxic conditions; then, intestinal lavage fluid and intestinal tissues were harvested. ELISA was used to detect D-lactic acid (D-LA), endotoxin (ET), diamine oxidase (DAO), intestinal fatty acid binding protein (i-FABP), liver-type fatty acid binding protein (L-FABP) and cytokines in the intestinal lavage of neonatal rats during hyperoxia. The intestinal zonula occluden-1 (ZO-1), occlusion protein (Occludin), and closure protein-4 (Claudin-4) of neonatal pups were detected by immunohistochemistry, western blotting, and real-time Polymerase chain reaction (RT-PCR) during hyperoxia. NCM460 cell survival rates were assayed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) during hyperoxia and administration of N-acetyl-L-cysteine (NAC). The expression levels of ZO-1, Occludin, and Claudin-4 in NCM460 cells were detected by immunohistochemistry, western blotting, and RT-PCR during hyperoxia and NAC. Results. D-LA, ET, L-FABP, i-FABP, DAO, TNF-alpha, IL-10, and IFN-gamma were significantly increased by hyperoxia, while ZO-1, Occludin, and Claudin-4 were clearly decreased in the hyperoxia group compared with the control group. NAC promoted cell survival, which was inhibited by hyperoxia. The cellular expression levels of ZO-1, Occludin, and Claudin-4, which were lowered by hyperoxia, were increased by NAC. Conclusion. Hyperoxia causes injury of the intestinal mucosa, and ROS plays a role in this intestinal damage during hyperoxia.

Characterization of a Sr co-doped LaBr3:(Ce) detector for gamma-ray spectroscopy

In this paper we report about thorough characterization of Sr2+ co-doped LaBr3 :Ce single crystal of dimensions 1.5 ” x 1.5 ”. The properties studied include energy resolution, timing resolution, internal activity, intrinsic photo-peak efficiency and linearity over a range of 661.7 keV to 4.43 MeV using multiple gamma-ray sources. While characteristics of regular Ce doped LaBr3 and its superiority over other inorganic crystals are now well established, the possibilities of improving them further by Sr2+ co-doping is a fledgling field of research. The primary aim of this work is to check whether addition of Sr by the manufacturer results in better performance than standard Lanthanum Bromide doped with Cerium. The results obtained were compared with measurements with standard LaBr3:Ce of similar size. The energy resolution of the co-doped crystal at 661.7 keV is same as that of a regular crystal of similar size and does not show any significant improvement. However, the timing resolution is found to be inferior to a similar LaBr3:Ce crystal. This is in conformity with reported measurement of spectral shape showing lengthening of decay time. Our result on energy resolution is at variance with previously published reports on very small volume co-doped crystals. Two very recent measurements with larger volume Sr co-doped crystals ( 1.5 ” x 1.5 ” and 3.0 ” x 3.0 ”) have also shown improvement in energy resolutions. We conclude that more measurements are probably required to proclaim Sr(2+ )co-doped LaBr3 as significantly superior to LaBr3:Ce, irrespective of the shape, size and PMTs used. The observed improvement in energy resolution has to be consistent regardless the volume and use of PMTs or APDs and is required to be significantly better to compensate for the deterioration in timing.

Behaviour of Human Oral Epithelial Cells Grown on Invisalign(R) SmartTrack(R) Material

Invisalign aligners have been widely used to correct malocclusions, but their effect on oral cells is poorly known. Previous research evaluated the impact of aligners’ eluates on various cells, but the cell behavior in direct contact with aligners is not yet studied. In the present study, we seeded oral epithelial cells (cell line Ca9-22) directly on Invisalign SmartTrack material. This material is composed of polyurethane and co-polyester and exhibit better mechanical characteristics compared to the predecessor. Cell morphology and behavior were investigated by scanning electron microscopy and an optical cell moves analyzer. The effect of aligners on cell proliferation/viability was assessed by cell-counting kit (CCK)-8 and 3,4,5-dimethylthiazol-2-yl-2,5-diphenyl tetrazolium bromide (MTT) assay and live/dead staining. The expression of inflammatory markers and proteins involved in epithelial barrier function was measured by qPCR. Cells formed cluster-like structures on aligners. The proliferation/viability of cells growing on aligners was significantly lower (p < 0.05) compared to those growing on tissue culture plastic (TCP). Live/dead staining revealed a rare occurrence of dead cells on aligners. The gene expression level of all inflammatory markers in cells grown on aligners' surfaces was significantly increased (p < 0.05) compared to cells grown on TCP after two days. Gene expression levels of the proteins involved in barrier function significantly increased (p < 0.05) on aligners' surfaces after two and seven days of culture. Aligners' material exhibits no cytotoxic effect on oral epithelial cells, but alters their behavior and the expression of proteins involved in the inflammatory response, and barrier function. The clinical relevance of these effects has still to be established. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Effect of pH and surfactants on the electrokinetic properties of nanoparticles dispersions and their application to the PET fibres modification

This paper presents the effect of surfactants, pH and electrolyte (0.1 x 10(-3) M KCI) on the stability of the aqueous dispersions of commercial ZnO and AgCu nanoparticles. As the surfactants cationic hexadecyltrimethylammonium bromide (CTAB), anionic sodium dodecyl sulfate (SDS), and nonionic 4-(1,1,3,3-tetramethylbutyl)phenyl polyethylene glycol (Triton X-100) at concentrations of 0.5 x 10(-3), 1.0 x 10(-3), and 0.1 x 10(-3) M, respectively, were used. The zeta potential values, z-average hydrodynamic diameter and long-term stability of ZnO and AgCu nanoparticles were examined by means of the dynamic light scattering (DLS) technique. It was found that the presence of ionic surfactants reduced the tendency of nanopartides for agglomeration/aggregation and improved their colloidal stability. They were characterized by high (vertical bar 70 vertical bar mV) and pH-independent zeta potential values. In addition, ZnO nanoparticles in the presence of ionic surfactants showed a better long-term stability than AgCu nanoparticles. Their z-average hydrodynamic diameters in CTAB and SDS were 195 +/- 2 nm and 295 +/- 5 nrn, respectively, and remained almost unchanged for 5 days. The addition of KCl improved the stability of aqueous and containing nonionic surfactant dispersions of nanoparticles, what was reflected in the zeta potential values > 30 mV in almost the entire pH range. The stability of nanoparticles dispersion significantly affects the uniformity of nanoparticles distribution on the fibres surface. The uniformity of distribution of the ZnO and AgCu dispersion on the surface of polyester (PET) fibres was carried out by means of microscopic methods (SEM/EDS). (C) 2020 Elsevier B.V.
