Although synthetic antioxidants (AOs) and photoinitiators (PIs) are known to be used in printing inks, there are little data on residual concentrations in printing paper products. In the present study, twenty-five PIs, ten AOs, and six transformation products were analyzed in two types of printing paper products, magazines and paperboard food packaging materials, both of which are unavoidable everyday products in our life. Nine AOs and six transformation products can be detected in food packaging materials with total concentrations (geometric mean, GM) of 1.16 x 10(4) ng/dm2. Twenty-two PIs were detected in food packaging materials with total concentrations (GM) of 1.76 x 10(4) ng/dm2. These chemicals were also detected in magazines, albeit at low concentrations (GM of AOs: 466 ng/dm(2), GM of PIs: 1.17 x 10(3) ng/dm(2)). Magazine front covers were found to have much higher concentrations of the target compounds than magazine inside pages. Tris(2,4-di-tert-butylphenyl) phosphate (AO168O), 2,6-di-tert-butyl-4-methylphenol (BHT), bisphenol A (BPA), and benzophenone (BP) were among the predominant chemicals in those printing paper products. Preliminary calculations suggest that dermal exposure to AOs (GM: 6.25 ng/day) and PIs (GM: 17.0 ng/day) via contact with printing paper products is a minor exposure pathway compared to food intake/dust ingestion and is exceedingly unlikely to cause adverse health effects.

A series of four-armed poly(d,l-lactide)-block-poly(l-lactide) (4-DL-D) copolymers were synthesized by ring-opening polymerization. By fixing the poly(d,l-lactide) (PDLLA) block length (1 kg mol(-1)) and changing the poly(d-lactide) (PDLA) block length (M-n,M-PDLA = 0, 0.5, 1.1, 1.3, 1.8 and 2.6 kg mol(-1)), the crystallization and alkaline degradation of the PLLA/4-DL-D blends were investigated. The four-armed PDLLA core of the copolymer inhibited the crystallization of PLLA, while the outer PDLA block could affect the crystallization differently when its length changed. If M-n,M-PDLA was 0 or 0.5 kg mol(-1), the crystallization of PLLA in the PLLA/4-DL-D blend was retarded markedly and the degradation rate of the blend films was much faster than that of neat PLLA film. Interestingly, when M-n,M-PDLA was 1.1 kg mol(-1) or higher, stereocomplex (SC) crystallites with different morphologies were formed, and the degradation rate of the PLLA/4-DL-D blend decreased gradually with increasing M-n,M-PDLA. In the PLLA/4-DL-D1.1 blend, the SC crystallites acted as nucleators for PLLA homocrystallites, while in the PLLA/4-DL-D1.3 blend, small isolated SC crystallites were observed inside the PLLA homospherulites. When M-n,M-PDLA was 1.8 or 2.6 kg mol(-1), a network structure of SC crystallites was formed and the degradation resistance of the films was markedly enhanced. A possible isothermal crystallization mechanism was proposed for the PLLA/4-DL-D blends, and the relationship between the crystallization state and degradation behavior was explored. This work revealed that the crystallization state, which was controlled by the PDLA block length, had a significant effect on the degradation behavior of PLLA/4-DL-D blend films.

Green synthesis of silver nanoparticles (AgNPs) was carried out using aqueous bark extract of Shorea robusta(Sal tree) as the reducing and capping agent. AgNPs were characterized using modern characterization tools like UV-Vis, PXRD, FT-IR, SEM, and HR-TEM. The catalytic application of the prepared AgNPs in three-component coupling reaction of aldehyde, malononitrile, and cyclic enamino ketone resulted in good to excellent yields of hexahydroquinoline derivatives. Moreover, the catalyst can be recycled up to 5 times without compromising too much yield. The mechanistic pathway was investigated employing GC-Mass spectroscopy and supported through the Density Functional Theory (DFT) calculations. A two-step mechanism has been proposed for the coupling reaction, and the presence of electron-withdrawing group in the aldehyde component is found to be more favorable than electron-releasing one in terms of yield with lesser time.

beta-Cyclodextrin-functionalized carbon nitride nanosheets were modified with a molecularly imprinted polymer to obtain a fluorescent probe of type MIP@beta-CD/CNNS which is shown to enable fluorometric determination of sterigmatocystin (STG). The material was characterized by transmission electron microscopy, infrared spectra, powder X-ray diffraction, X-ray photoelectron spectroscopy, and by absorption and emission spectra. The modified CNNSs have a good fluorescence quantum yield (13%), high sorption capacity for STG (86 mg center dot g(-1)), fast adsorption rate (25 min), and superior adsorption selectivity (with an imprint factor 2.56). When used as an optical probe for STG, the CNNSs act as the chromophore, while beta-CD and MIP act as the recognition groups. The blue fluorescence of MIP@beta-CD/CNNS (with excitation/emission maxima at 368/432 nm) is quenched by STG. Fluorescence drops linearly in the 0.15 to 3.1 mu M STG concentration range. The lower detection limit is 74 nM. The method was successfully applied to the determination of STG in spiked wheat extract. Conceivably, this detection scheme based on a combination of beta-CD inclusion and molecular imprinting may be extended to the detection of various other organic compounds.

A new aromatic diamine, 10,10-bis[4-(4-aminophenoxy)phenyl]-9(10H)-anthrone (BAPA) has been synthesized from anthrone via three-step procedure. Direct phosphorylation polycondensation of BAPA with various aromatic dicarboxylic acids produced a series of cardo poly(ether amide)s with inherent viscosities of 0.97-1.29 dL g(-1). All the polymers were readily soluble in polar solvents such as N-methyl-2-pyrrolidone, N, N-dimethylacetamide (DMAc), and pyridine at room temperature, and afforded transparent, strong, and flexible films upon casting from DMAc solvent. The resulting poly(ether amide)s had glass transition temperatures of 254-316 degrees C, 10% weight loss temperatures of 495-524 degrees C, and char yields of 55-70% at 800 degrees C in nitrogen. These polymers were amorphous and their films exhibited tensile strengths of 81.6-104.7 MPa, tensile moduli of 1.8-2.4 GPa, and elongations at break of 8-15%.

Defect engineering of nanomaterials has emerged as a promising approach to improve their performance for pollutant removal. However, various nanomaterial defects play variant roles in environmental applications. It is still a challenge to construct multiple defects of composite materials into advantageous aggregates to deal with complicated matrix pollution. In this work, we investigated a series of three-dimensional defect-optimized aerogels (3D DOAs) of graphene oxide (GO) with a covalent triazine framework (CTF) for improved adsorption and photoregeneration performance via tailoring duet carbon and nitrogen defects. Using chemical reduction, carbon defects in GO were gradually repaired and nitrogen defects in CTF were created simultaneously. The carbon defect engineering generated additional nonpolarized electron-depleted sites in GO of 3D DOA for increased adsorption capacities (2417 mu mol/g for benzophenone, 2209 mu mol/g for 4-hydroxybenzophenone, 1957 mu mol/g for 2,2′,4,4′-tetrahydroxybenzophenone). Meanwhile, increasing nitrogen defects of the CTF in 3D DOA would produce midgap states for an extended absorption range of visible light and increased photocatalytic activity to remove adsorbed pollutants. The enhanced adsorption and the superior photocatalytic regeneration soundly corroborated that the performance of 3D DOA was improved effectively by the defect optimization strategy. Moreover, the high stability of 3D DOA and its practical usage were verified in a real water matrix with a 7-day cycle test. The present work highlights an approach of defect optimization for development of a solar-driven, self-regenerative adsorbent for water purification with high efficiency.

The oxidation of aldehydes is an efficient methodology for the synthesis of carboxylic acids. Herein we hope to report a simple, efficient and recyclable protocol for aerobic oxidation of aldehydes to carboxylic acid by using C3N4 supported silver nanoparticles (Ag/C3N4) as a catalyst in aqueous solution under mild conditions. Under standard conditions, the corresponding carboxylic acids can be obtained in good to excellent yields. In addition, Ag/C3N4 is convenient for recovery and could be reused three times with satisfactory yields.

N-Alkyl nitrones are used as the starting materials to construct various N-aryl isoxazolidines, instead of N-alkyl isoxazolidines or N-H 1,3-oxazinanes via a catalyst-free one-pot three-component reaction with nitroso compounds and olefins. The mechanism investigations indicate that the in situ formation of N-aryl nitrones from the reaction of N-alkyl nitrones and nitrosoarenes is the key step. The protocol features broad substrate scope, good to excellent chemo-, regio- and diastereo-selectivities, and moderate to excellent yields for most substrates.

Rationale Mummification is one of the defining customs of ancient Egypt. The nuances of the embalming procedure and the composition of the embalming mixtures have attracted the attention of scientists and laypeople for a long time. Modern analytical tools make mummy studies more efficient. Methods Comprehensive two-dimensional gas chromatography-high resolution mass spectrometry (GCxGC/HRMS) with complementary ionization methods (electron ionization, positive chemical ionization, and electron capture negative ionization [ECNI]) with a Pegasus GC-HRT+4D instrument was used to identify embalming components in the mummy from the Pushkin Museum of Fine Arts acquired in 1913 in London at the de Rustafjaell sale. The mummy dates back to the late Predynastic period (direct accelerator mass spectrometry-dating 3356-3098 bc), being one of the oldest in the world. Results The results showed the complexity of the embalming mixtures that were already in use 5000 years ago. Several hundred organic compounds were identified in the mummy samples. Various types of hydrocarbons (triterpanes, steranes, isoprenoid, and polycyclic aromatic hydrocarbons) prove the presence of petroleum products. Iodinated compounds detected using ECNI define oils of marine origin, whereas esters of palmitic acid indicate the use of beeswax. The nature of the discovered components of conifer tar proves that the preliminary processing of conifer resins involved heating. GCxGC/HRMS also allowed a number of modern contaminants (phthalates, organophosphates, and even DDT) to be identified. Conclusions Application of a powerful GCxGC/HRMS technique with complementary ionization methods allowed significant widening of the range of organic compounds used for mummification that could be identified. The complexity of the embalming mixtures supports the hypothesis of the high social status of the child made on the basis of the preliminary study of the mummy.
