The design of novel materials to use simultaneously in an ocular system for driven therapeutics and wound healing is still challenging. Here, we produced nanocomposites of tungsten disulfide carriers with spherical cobalt ferrite nanoparticles (NPs) as core inside a cubic iron oxide NPs shell (WS2/s-CoFe2O4@c-Fe3O4). Transmission electron microscopy (TEM) confirmed that 10 nm s-CoFe2O4@c-Fe3O4 NPs were attached on the WS2 sheet surfaces. The cytotoxicity of the WS2 sheets and nanocomposites were evaluated on bovine cornea endothelial cells (BCECs) using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for a duration of three days. The MTT assay results showed low toxicity of the WS2 sheets on BCECs by 67% cell viability at 100 mu g/mL in 24 h, while the nanocomposites show 50% cell viability in the same conditions. The magnetic resonance imaging (MRI) of nanocomposites revealed the excellent T-2-weighted imaging with an r(2) contrast of 108 mM(-1) S-1. The in vitro photothermal therapy based on WS2 sheets and WS2/s-CoFe2O4 @c-Fe3O4 nanocomposites using 808 nm laser showed that the maximum thermal energy dispatched in medium at different applied power densities (1200 mw, 1800, 2200, 2600 mW) was for 0.1 mg/mL of the sample solution. The migration assay of BCECs showed that the wound healing was approximately 20% slower for the cell exposed by nanocomposites compared with the control (no exposed BCECs). We believe that WS2/s-CoFe2O4@c-Fe3O4 nanocomposites have a synergic effect as photothermal therapy agents for eye diseases and could be a target in an ocular system using MRI.

As a fundamental type of carbonylation reaction, the alkoxy- and hydroxy-carbonylation of unsaturated hydrocarbons constitutes one of the most important industrial applications of homogeneous catalysis. However, owing to the difficulties in controlling multi-selectivities for asymmetric hydrocarbonylation of alkenes, this reaction is typically limited to vinylarenes and analogues. In this work, a highly efficient asymmetric alkoxy- and hydroxy-carbonylation of beta-carbonyl functionalized alkenes was developed, providing practical and easy access to various densely functionalized chiral molecules with high optical purity from broadly available alkenes, CO, and nucleophiles (>90 examples, 84-99 % ee). This protocol features mild reaction conditions and a broad substrate scope, and the products can be readily transformed into a diverse array of chiral heterocycles. Control experiments revealed the key role of the beta-carbonyl group in determining the enantioselectivity and promoting the activity, which facilitates chiral induction by coordination to the transition metal as rationalized by DFT calculations. The strategy of utilizing an innate functional group as the directing group on the alkene substrate might find further applications in catalytic asymmetric hydrocarbonylation reactions.

Atmospheric brown carbon (BrC) has recently attracted great concerns due to its potential contribution to climate change. It was reported that dissolved Fe(III) species can act as an efficient oxidant to catalyze the polymerization of volatile phenol substances, subsequently forming atmospheric BrC in aerosols. Since Fe in the atmosphere is commonly associated with clay mineral dusts, the transformation of phenol substances on Fe-bearing clay mineral surface is potentially important for BrC formation. In this study, taking guaiacol as the model phenol substance, its brown carbon formation process was investigated on Fe(III) modified montmorillonite under different relative humidities (RHs). The spectroscopic features and compositions of the produced BrC were systematically characterized. The results demonstrated that the interface FeOH2+ is the key species to promote the polymerization of guaiacol, and RH plays a significant role to influence the surface acidity of clay and the gas-to-particle adsorption of guaiacol. The BrC was produced with the most abundance and variety under moderate RH (similar to 33%), while higher RH (similar to 100%) accelerated the polymerization rate. Since aerosol moisture content might not largely influence the hydroxylation states of the surface bearing Fe(III) species, it signifies the importance of clay associated Fe(III) to catalyze the BrC formation in varied conditions Our study highlights the importance of clay mineral dust on the formation of BrC, and reveals the brown carbon formation pathways under environmentally relevant conditions.

Polyoxymethylene dimethyl ethers (PODE, with the formula of CH3O-(CH2O)(n)-CH3), as a promising environmentally benign diesel fuel or additive with an enormous potential in the reduction of soot and NIC, emissions, can be efficiently synthesized from methanol derivatives such as dimethoxymethane (DMM) and trioxymethylene (TOM), which requests a proper catalyst of high performance. In this work, the catalytic performance of graphene oxide (GO) in the synthesis of PODEn as well as its relation to the catalyst structure was thoroughly investigated. The results indicate that GO is an excellent catalyst in the synthesis of PODEn from DMM and TOM; a TOM conversion of 94.6% and selectivity of 86.0% to PODE2-8 are achieved under mild reaction conditions, which is superior to the majority of the state-of-the-art catalysts. Meanwhile, the active species and characteristic layer structure of GO sheets catalytically responsible for PODEn formation were discriminated through selectively removing certain surface functional groups, thermally annealing at different temperatures, and carefully comparing with a series of model compounds. The results illustrate that the superior catalytic performance of GO in the PODEn synthesis should be ascribed to a synergy between the surface sulfonyl, hydroxyl and carboxyl groups present on the GO surface and the unique layered structure of GO sheets, wherein the surface sulfonyl groups act as the main active sites. The insights shown in this work are beneficial to a deep understanding on the catalytic principle of GO and development of efficient catalyst for the synthesis of PODEn.

Psoralen is a furocoumarin natural product that intercalates within DNA and forms covalent adducts when activated by ultraviolet radiation. It is well known that this property contributes to psoralen’s clinical efficacy in several disease contexts, which include vitiligo, psoriasis, graft-versus-host disease and cutaneous T-cell lymphoma. Given the therapeutic relevance of psoralen and its derivatives, we attempted to synthesize psoralens with even greater potency. In this study, we report a library of 73 novel psoralens, the largest collection of its kind. When screened for the ability to reduce cell proliferation, we identified two derivatives even more cytotoxic than 4 ‘-aminomethyl-4,5 ‘,8-trimethylpsoralen (AMT), one of the most potent psoralens identified to date. Using MALDI-TOF MS, we studied the DNA adduct formation for a subset of novel psoralens and found that in most cases enhanced DNA binding correlated well with cytotoxicity. Generally, our most potent derivatives contain positively charged substituents, which we believe increase DNA affinity and enhance psoralen intercalation. Thus, we provide a rational approach to guide efforts toward further optimizing psoralens to fully capitalize on this drug class’ therapeutic potential. Finally, the structure-activity insights we have gained shed light on several opportunities to study currently underappreciated aspects of psoralen’s mechanism.

Infrared spectroscopy can provide significant insight into the structures and dynamics of molecules of all sizes. The information that is contained in the spectrum is, however, often not easily extracted without the aid of theoretical calculations or simulations. We present here the calculation of the infrared spectra of a database of 703 gas phase compounds with four different force fields (CGenFF, GAFF-BCC, GAFF-ESP, and OPLS) using normal-mode analysis. Modern force fields increasingly use virtual sites to describe, e.g., lone-pair electrons or the o -holes on halogen atoms. This requires some adaptation of code to perform normal-mode analysis of such compounds, the implementation of which into the GROMACS software is briefly described as well. For the quantitative comparison of the obtained spectra with experimental reference data, we discuss the application of two different statistical correlation coefficients, Pearson and Spearman. The advantages and drawbacks of the different methods of comparison are discussed, and we find that both methods of comparison give the same overall picture, showing that present force field methods cannot match the performance of quantum chemical methods for the calculation of infrared spectra.

A novel interzeolite transformation strategy using internally confined organic structure directing agents (OSDAs), called the OSDA-confined strategy, is proposed for highly crystalline nanosized high-silica ZSM-5 zeolite synthesis, by which high yield and fast synthesis of ZSM-5 is achieved using BEA zeolite as a raw material. The transformation process was investigated by XRD, SEM, ICP, FTIR and UV Raman spectroscopy, which revealed that the decomposition of a parent zeolite and the crystallization process of products were well modulated by the confined OSDA. The transformation process could be divided into three stages consisting of raw material deconstruction, small size product formation and product growth. The strong etching power of NaOH contributes to the fast decomposition of BEA zeolites. In addition, tetrapropylammonium hydroxide (TPAOH) as an OSDA was confined in the parent zeolite instead of being added into the mother liquid, achieving a high local concentration of TPAOH, which could reduce the decomposition rate of the parent BEA zeolite and promote the efficient organization of the building units generated by the decomposition of the BEA zeolite. Thereof, a high yield was achieved by the synergistic effect of NaOH and occluded TPAOH. During the interzeolite transformation process, the six-membered rings (6Rs), five-membered rings (5Rs) and four-membered rings (4Rs) in the BEA zeolite framework were disassembled and combined with the help of 5Rs to produce the ZSM-5 zeolite structure. Moreover, due to the nanoscale and large surface area, the obtained ZSM-5 zeolite catalyst showed extremely high catalytic activity in the self-etherification reaction of benzyl alcohol (BA) to dibenzyl ether (DE). This study provides insights into the interzeolite transformation process, which would be helpful for achieving size control and high-efficiency synthesis.

Superparamagnetic nanoparticles (SPIONs) can be used as nuclear magnetic resonance (NMR) signal enhancement agents for petroleum exploration. This enhancement effect is uniform if SPIONs are monodisperse in size and in composition; yet it is challenging to synthesize mono disperse particles that do not aggregate in high salinity petroleum brine. Here, we report a method to synthesize individual SPIONs coated with tunable surface coating densities of poly(2-acrylamido-2-methyl-1-propanesulfonic acid (pAMPS) with a catechol end-group (pAMPS*). To establish parameters under which pAMPS*-coated SPIONS do not aggregate, we compared computational predictions with experimental results for variations in pAMPS* chain length and surface coverage. Using this combined theoretical and experimental approach, we show that singly dispersed SPIONs remained stabilized in petroleum brine for up to 75 h with high surface density pAMPS*.

Nanoparticles layered with palladium(0) were prepared from nano-sized magnetic Fe3O4 by coating it with silica and then reacting sequentially with phenylselenyl chloride under an N-2 atmosphere and palladium(ii) chloride in water. The resulting Fe3O4@SiO2@SePh@Pd(0) NPs are magnetically retrievable and the first example of NPs in which the outermost layer of Pd(0) is mainly held by selenium. The weight percentage of Pd in the NPs was found to be 1.96 by ICP-AES. The NPs were authenticated via TEM, SEM-EDX, XPS, and powder XRD and found to be efficient as catalysts for the C-O and C-C (Suzuki-Miyaura) coupling reactions of ArBr/Cl in water. The oxidation state of Pd in the NPs having size distribution from similar to 12 to 18 nm was inferred as zero by XPS. They can be recycled more than seven times. The main features of the proposed protocols are their mild reaction conditions, simplicity, and efficiency as the catalyst can be separated easily from the reaction mixture by an external magnet and reused for a new reaction cycle. The optimum loading (in mol% of Pd) was found to be 0.1-1.0 and 0.01-1.0 for O-arylation and Suzuki-Miyaura coupling, respectively. For ArCl, the required amount of NPs was more as compared to that needed for ArBr. The nature of catalysis is largely heterogeneous.

Environmental contamination by organophosphate flame retardants (OPFRs) and plasticizers are environmental concerns. In this study, 18 OPFRs were analyzed in sediment and bivalves collected from 50 locations along the Korean coast to assess occurrence, geographical distribution, contamination source, and bioaccumulation potential. Tris(1-chloro-2-propanyl) phosphate (TCPP) and tris(2-ethylhexyl) phosphate (TEHP) were highly detected (> 80%) OPFRs in sediment and bivalves. Total concentrations of OPFRs and plasticizers in sediment and bivalves ranged from 2.18 to 347 ng/g dry weight and from 6.12 to 206 ng/g dry weight, respectively, which were within the ranges reported for previous studies. Sedimentary organic carbon was a primary factor governing the OPFR distribution. Concentrations of OPFRs and plasticizers in sediments from harbor zones were significantly higher than non-harbor zones, indicating that shipping activity is a contamination source of OPFRs and plasticizers in coastal environments. Biota-sediment accumulation factors < 1 for several OPFRs indicated limited potential for bioaccumulation.
