Xu, Niansheng published the artcileHelical polycycle molecular semiconductor for durable and efficient perovskite solar cells, Application of 4-Methoxy-N-methylaniline, the main research area is polycycle mol semiconductor perovskite solar cell perovskite layer.

Despite the efficiency comparable to crystalline silicon photovoltaics, it is still a severe concern on the long-term stability under the stress of heat, light, and bias potential for perovskite solar cell (PSC). Here, we report a triple aza[6]helicene-based mol. semiconductor (TBTA[6]H) characteristic of a fully fused conjugated backbone. TBTA[6]H presents superior solubility and glass-transition temperature (Tg). An air-doped composite of TBTA[6]H with a high elec. conductivity of 353μS cm-1 is still featured by a Tg of 112°C, enabling the fabrication of 22% efficiency, 85°C durable PSCs. The TBTA[6]H composite not only exhibits an excellent morphol. stability at 85°C in PSCs, but also remarkably attenuates the thermal degradation of photoactive perovskite layer. The cell with TBTA[6]H also displays an excellent operation stability under the continuous full sunlight soaking at 55°C.

Zhang, Hongyang published the artcileGC-MS profiling of volatile components in different fermentation products of Cordyceps sinensis mycelia, Safety of 5-Methyl-2-phenylhex-2-enal, the main research area is fermentation Cordyceps sinensis; Cordyceps sinensis mycelia; Simultaneous distillation-extraction; fermentation products; gas chromatography-mass spectrometry; partial least squares-discriminant analysis; quality evaluation; volatile profiling.

The fermentation products of Cordyceps sinensis (C. sinensis) mycelia are sustainable substitutes for natural C. sinensis. However, the volatile compositions of the com. products are still unclear. In this paper, we have developed a simultaneous distillation-extraction (SDE) and gas chromatog.-mass spectrometry (GC-MS) method for the profiling of volatile components in five fermentation products. A total of 64, 39, 56, 52, and 44 components were identified in the essential oils of Jinshuibao capsule (JSBC), Bailing capsule (BLC), Zhiling capsule (ZLC), Ningxinbao capsule (NXBC), and Xinganbao capsule (XGBC), resp. 5,6-Dihydro-6-pentyl-2H-pyran-2-one (massoia lactone) was first discovered as the dominant component in JSBC volatiles. Fatty acids including palmitic acid (C16:0) and linoleic acid (C18:2) were also found to be major volatile compositions of the fermentation products. The multivariate partial least squares-discriminant anal. (PLS-DA) showed a clear discrimination among the different com. products as well as the counterfeits. This study may provide further chem. evidences for the quality evaluation of the fermentation products of C. sinensis mycelia.

Senol, Ayse Merve published the artcileSynthesis and photophysical properties of new pyrazolines with triphenyl and ester derivatives, Formula: C9H10O3, the main research area is phenylbenzohydrazonoyl chloride methyl cinnamate diastereoselective dipolar cycloaddition; methyl triphenyl dihydropyrazole carboxylate preparation absorption fluorescence solvatochromism.

New (4S*,5S*)-Me 3-(2,3-dimethoxyphenyl)-5-(3,4-dimethoxyphenyl)-1-phenyl-4,5-dihydro-1H-pyrazole-4-carboxylate and its isomer were synthesized from 1,3-dipolar cycloaddition reaction of a hydrazonyl chloride with a cinnamic acid derivative and solvent effects on absorption and fluorescence properties of the novel synthesized pyrazoline derivatives were studied by UV-Vis. absorption and steady-state fluorescence spectroscopy techniques. The absorption and fluorescence spectra for both isomers showed that solvent structure and polarity have effect on photophsical properties of the isomer mols. Isomers exhibited pos. solvatochromism behavior when the polarity of the solvent was increased from p-Xylene to MeOH. Furthermore, isomers showed very high quantum yields in the solvents except for polar solvents and bromobenzene. Solute-solvent interactions were analyzed by using the solvent polarity parameter (ET(30)) approach, Lippert-Mataga equation, Kamlet-Taft and Catalan multiple linear regression anal. These results revealed that the most contributing factor of solute-solvents interactions for the isomer 4 was the solvent acidity whereas the most contributing factors for isomer 5 was the solvent acidity as well as the solvent polarity.

Black soybean sauce’s (BSS) aroma was scarcely investigated, which seriously affected BSS’s quality and consumers’ preference. Thus the aroma compounds in BSS were characterized using gas chromatog.-mass spectrometry/gas chromatog.-olfactometry coupling with recombination and omission experiments Sensory evaluation showed the fruity odor was increased by 63% and the malty, alc., floral, smoky, caramel-like and sour odors were decreased by 24-35% when compared to the control soy sauce (SS, p < 0.05). Totally, 126 volatile compounds, 44 aroma-active compounds and 22 vital aroma-active compounds were identified in BSS. Compared to SS, BSS exhibited a distinctive aroma characteristics which was caused by significantly higher odor activity values (OAVs) of 3-methylbutyl acetate (357%), Et propanoate (144%), Et 3-methylbutanoate (70%), Et 2-methylbutanoate (102%) and lower OAVs of 4-hydroxy-2,5-dimethyl-3(2H)-furanone (52%), 4-hydroxy-2-ethyl-5-methyl-3(2H)-furan-3-one (50%), ethanol (48%), 4-vinylguaiacol (41%), 3-methylthiopropanal (37%), 3-methylbutanol (33%), 4-ethylguaiacol (28%). The results would contribute to BSS's quality control and aroma improvement.

Strojnik, Lidija published the artcileSpecies and geographic variability in truffle aromas, Safety of 1,3-Dimethoxybenzene, the main research area is Tuber odor volatile compound quality; Aroma variability; Geographical origin; Quality; Truffle; Volatile organic compounds.

The gastronomic relevance and price of truffles are related mainly to its unique aroma. In this study, we explore the impact that different volatile compounds have on the aroma quality of fresh truffles using gas chromatog.-mass spectrometry (GC-MS). Four hundred sixty fresh ascocarps of nine truffle species (Tuber aestivum, Tuber magnatum, Tuber melanosporum, Tuber mesentericum, Tuber brumale, Tuber excavatum, Tuber rufum, Tuber indicum and Tuber macrosporum) harvested in 2018/19 and 2019/2020 from 11 different countries (Slovenia, Croatia, Bosnia in Herzegovina, Macedonia, Italy, Spain, France, United Kingdom, Germany, Poland and China) were collected. Our investigation included the classification of species based on their aroma profile, a study of the differences in the volatile organic composition of truffle species over a geog. area, and, in more detail, a study of T. aestivum from four natural truffle growing sites in Slovenia. Our models can distinguish between groups, with small classification error. These models could form the basis of a predictive framework to detect fraud concerning truffle products and to determine the influence of different growing parameters on the aroma profile of truffles.
