Fu, Yu published the artcileMandelic Acid as an Interfacial Modifier for High Performance NiO_x-based Inverted Perovskite Solar Cells, HPLC of Formula: 90-64-2, the publication is ChemNanoMat (2022), 8(7), e202200091, database is CAplus.

Nickel oxide (NiO_x) inverted perovskite solar cells have been witnessed as promising solar cells because of the low cast, easy fabrication and negligible hysteresis. However, the inferior interface feature of the link NiO_x and perovskite layer often causes poor device property and repeatability. Here, Mandelic acid (MAD) is introduced to form a modified layer, which could improve the poor interface properties between perovskite layer and NiO_x layer. The contact angel images revels MAD could increase the hydrophobicity and facilitate the growth of perovskite crystal. The X-ray diffraction pattern and Fourier transform IR spectroscopy have confirmed that the MAD small mol. could interact with residual PbI₂ crystal, leading to better interface contact and high crystallinity. This is further demonstrated by the SEM test of NiO_x/MAD/MAPbI₃ film that average grain size is increased from 201.85 nm to 315.17 nm. The space-charge limited current measurement proves the introduction of MAD mol. that result in the decreased trap state d. from 3.58×10¹⁵ cm^-3 to 2.721015 cm^-3. As a consequence, The power conversion efficiency is significantly improved from 14.9% to 18.42% of MAPbI₃-based devices that retained nearly 80% initial PCE after 50 days in N₂ without encapsulation.

The unprecedented triarylcarbonium ion-pair-catalyzed Pictet-Spengler reaction of tryptamines with aromatic aldehydes and cyclic ketones in water was disclosed. Under metal-free conditions, diverse tetrahydro-β-carbolines/spirocyclic tetrahydro-β-carbolines I [R¹ = H, Me, Cl, etc.; R² = H; R³ = Ph, 4-MeC₆H₄, 2-naphthyl, etc.; R²R³ = (CH₂)₅, CH₂CH₂CH(Me)CH₂CH₂, CH₂CH₂N(Boc)CH₂CH₂, etc.] were obtained in good yields with excellent functional group tolerance, including late-stage modification of natural products and small mol. drugs. The practicability of this protocol was also characterized in the gram-scale synthesis of komavine and several other functional compounds Preliminary mechanistic studies indicated that in aqueous media the in situ-generated superacidic species from the carbonium ion pair with water was crucial to promote the Pictet-Spengler reaction.

Zhao, Yong published the artcileAchieving the low interfacial tension by balancing crystallization and film-forming ability of the cathode interlayer for organic solar cells, HPLC of Formula: 239075-02-6, the publication is Journal of Colloid and Interface Science (2022), 880-890, database is CAplus and MEDLINE.

A series of mols. with imide units bridged by the core of thiophene-based groups, namely N-dimethylaminopropyl-4-thiophene-1,8- naphthalimide (NT), bis(N-dimethylaminopropyl)-4-thiophene-1,8-naphthalimide (NTN), and bis(N-dimethylaminopropyl)-4-bithiophene-1,8-naphthalimide (N2TN), have been reported as cathode interfacial materials (CIMs) to realize low interfacial tension with the blend in organic solar cells (OSCs). We evaluated the Ohmic contact between the active layer and these cathode interlayers based on various characterizations, which is of great significance for further understanding these imide-based interlayers. It turned out that the homogeneous and continuous NTN interlayer as a CIM balanced the factors of crystallization and film-forming property, and broke through the limitation of poor conductivity and high aggregation in our previous work. Moreover, compared with NT and N2TN, the NTN interlayer achieve a combination of good solubility in methanol, efficient electron mobility, and aligned work function. These advantages of NTN are conducive to the realization of high-efficient interfacial electron collection and transfer, thus improving the short-circuit c.d. (JSC) and filling factor (FF) of devices. Therefore, the binary OSCs (PM6:Y6) based on NTN engineered aluminum-cathode with excellent stability demonstrate a maximum power conversion efficiency (PCE) of 16.56 %, which is higher than NT (PCE = 1.34 %) and N2TN (PCE = 13.90 %). The enhanced performance is ascribed to the improvement of JSC and FF, which is originated from the outstanding conductivity and high-quality interface of NTN. Surprisingly, the PM6:Y6-based semitransparent device with NTN obtain a PCE of 13.43 % with an average visible transmittance of 17.79 %, which is better than traditional PDINO. This study highlights a potential strategy for enhancing the performance of OSCs by the interface engineering via decreasing the interfacial intension.

Xu, Xingjian published the artcilePotential biodegradation of phenanthrene by isolated halotolerant bacterial strains from petroleum oil polluted soil in Yellow River Delta, Category: alcohols-buliding-blocks, the publication is Science of the Total Environment (2019), 1030-1038, database is CAplus and MEDLINE.

The Yellow River Delta (YRD), being close to Shengli Oilfield, is at high risk for petroleum oil pollution. The aim of this study was to isolate halotolerant phenanthrene (PHE) degrading bacteria for dealing with this contaminates in salinity environment. Two bacterial strains assigned as FM6-1 and FM8-1 were successfully screened from oil contaminated soil in the YRD. Morphol. and mol. anal. suggested that strains FM6-1 and FM8-1 were belonging to Delftia sp. and Achromobacter sp., resp. Bacterial growth of both strains was not dependent on NaCl, however, grew well under extensive NaCl concentration The optimum NaCl concentration for bacterial production of strain FM8-1 was 4% (m/v), whereas for strain FM6-1, growth was not affected within 2.5% NaCl. Both strains could use the tested aromatic hydrocarbons (naphthalene, phenanthrene, fluoranthene and pyrene) and aliphatic hydrocarbons (C12, C16, C20 and C32) as sole carbon source. The optimized biodegradation conditions for strain FM6-1 were pH 7, 28 °C and 2% NaCl, for strain FM8-1 were pH 8, 28 °C and 2.5% NaCl. The highest biodegradation rate of strains FM6-1 and FM8-1 was found at 150 mg/L PHE and 200 mg/L, resp. In addition, strainsFM8-1 showed a superior biodegradation ability to strain FM6-1 at each optimized condition. The PHE biodegradation process by both strains well fitted to first-order kinetic models and the k₁ values were calculated to be 0.1974 and 0.1070 per day. Strain FM6-1 metabolized PHE via a “phthalic acid” route, while strain FM8-1 metabolized PHE through the “naphthalene” route. This project not only obtained two halotolerant petroleum hydrocarbon degraders but also provided a promising remediation approach for solving oil pollutants in salinity environments.

This paper aims to explore the clin. anal. of carbetocin combined with romethamine for preventing high-risk postpartum hemorrhage after caesarean section. 76 Cases of high-risk factor caesarean section puerpera were divided into control group and treatment group(n=38). In control group, the puerpera were injected with oxytocin 20 IU right after delivery, and i.v. infused with carbetocin 100 μg. Based on the treatment of control group, the treatment group was injected with romethamine 250 μg. The hemorrhage amount, side effect of drug and exhaust time in both groups were observed during operation, 2 h and 24 h after operation. The hemorrhage amounts during operation, 2 h and 24 h after operation in treatment group were significantly less than those of control group(all P<0.05). The exhaust time of treatment group was shorten than that of control group(P<0.05). There were no significant differences in drug side effects between two groups. Carbetocin combined with romethamine has definite effect and less side effect for preventing high-risk postpartum hemorrhage after caesarean section.

The synthesis of the target compounds was achieved using as reactants 3-phenyl-5-isoxazolecarbonyl chlorides and N⁵-[(phenylamino)carbonyl]lysine and the products thus obtained were confirmed by IR, ¹H-NMR and elemental anal. The biol. activity was examined in vivo and it was discovered that most compounds possessed moderate herbicidal activity. Meanwhile, the e activity of one compound was evaluated against spinach D1 protease (i.e., thylakoid protein precursor processing peptidase, chloroplast protein precursor-processing proteinase, photosystem D1 protein precursor carboxyl-terminal processing proteinase, proteinase CtpA) and the result showed its inhibiting effect against this enzyme.
