The enantioselective α-alkenylation of aldehydes has been accomplished using boronic acids via the synergistic combination of copper and chiral amine catalysis. The merger of two highly utilized and robust catalytic systems has allowed for the development of a mild and operationally trivial protocol for the direct formation of α-formyl olefins employing common building blocks for organic synthe...

In the present work, we compared chemical profile of organic compounds produced in non-catalytic pyrolysis sugarcane bagasse at 500 °C with those obtained by in-line catalytic upgrading vapor phase 350 °C. The influence over was evaluated testing two Ni-based catalysts employing an inert atmosphere (N2) and a reactive (H2) under atmospheric pressure yields liquid varying from 55 to 62%. Major c...

Cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) are two major inflammatory mediators. Here we show that iNOS specifically binds to COX-2 and S-nitrosylates it, enhancing COX-2 catalytic activity. Selectively disrupting iNOS-COX-2 binding prevented NO-mediated activation of COX-2. This synergistic molecular interaction between two inflammatory systems may inform the developme...

In this work, the g-C 3 N 4 /V 2 C MXene composite catalyst was prepared by solvothermal method, and its denitration performance under synergistic plasma (NTP) investigated. The results showed that when mass ratio of V is 3%, V-CN-3-NTP as high 83.3%, which 1.2 2.1 times C-NTP -NTP systems alone. apparent morphology, phase structure, catalytic mechanism were studied SEM, TEM, XRD, FTIR, XPS, et...

Discharge of non-biodegradable plastic waste and lignocellulosic biomass into the environment, resultant pollution has persistently increased all over globe. This activity poses a threat not only to mankind, but also environment. In addressing this challenge, catalytic co-pyrolysis (CCP) is one attractive ways used reduce these types waste, while simultaneously obtaining an alternative for conv...

The acidic ionic liquid (IL) functionalized polymer (PDVB-SO3H-[C3vim][SO3CF3]) possesses abundant nanoporous structures, strong acid strength and unique capability for deconstruction of crystalline cellulose into sugars in ILs. The polymer shows much improved catalytic activities in comparison with mineral acids, homogeneous acidic ionic liquids and the acidic resins such as Amberlyst 15. The ...

Non-steroidal anti-inflammatory drugs (NSAIDs) are known to enhance the responsiveness of tumor cells toward chemotherapeutic drugs and radiation. However, the precise mechanism of synergistic enhancement in tumoricidal activity is not clearly known. Herein, we demonstrate that the combination treatment of arsenic trioxide (As2O3) and sulindac resulted in a synergistic augmentation of cytotoxic...

Abstract This study proposes a new method for producing α-Fe 2 O 3 –CuO nanocatalyst that is both cost-effective and ecologically benign. The nanocomposite was prepared via moderate thermal oxidative decomposition of copper hexacyanoferrate. Its structure surface morphology are affirmed XRD, SEM, FTIR, EDX, TEM, XPS, VSM. In the presence H , employed as heterogeneous catalyst to stimulate therm...

Converting CO2 into high value-added chemicals by renewable energy directly alleviates the problem of resource shortages, while also reduces amount in atmosphere. Among various reduction methods, electroreduction has attracted much attention because its moderate operating conditions and a green easy-to-scale strategy. In this work, four catalyst enhancement mechanisms: synergistic effect, strai...
