Nowadays, the addition of nanoparticles to polymer solutions would be interest; however, feasible property and their impact on oil recovery has not been investigated in more detail. This study investigates rheology capillary forces (interfacial tension contact angle) performances during processes. Thereby, a sequential injection water, polymer, nanoparticles; Nanosilica (SiO2) nano-aluminium oxide (Al2O3) was performed measure factor. Retention decrease, reduction, viscoelastic behavior...
In this study, the pH-responsive API-CMCS-SA (ACS) polymeric nanoparticles (NPs) based on 1-(3-amino-propyl) imidazole (API), stearic acid (SA), and carboxymethyl chitosan (CMCS) were fabricated for effective transport of curcumin (CUR) in liver cancer. CUR-ACS-NPs with various degrees substitution (DS) employed to prepare through ultrasonic dispersion method. The effect different DS NPs formation was discussed. obtained (DSSA=12.4%) had high encapsulation rate (more than 85%) uniform...
Recent studies have shown that the composite of semiconductor photocatalytic materials and g-C3N4 can effectively inhibit carrier recombination enhance adsorption performance materials, so photocatalyst has stronger activity. In this paper, three kinds graphitic carbon nitride with different morphologies were prepared using same precursor system by chemical cracking method. After characterization application, sample most significant activity was selected g-C3N4/BiVO4 heterostructure...
With the unprecedented progress of biomedical nanotechnology in past few decades, traditional drug delivery systems (DDSs) have been incorporated into intelligent DDSs with stimulus responsive characteristics. Graphene oxide (GO) and Chitosan (CS) excellent physical, chemical, mechanical, optical properties, their synergistic effects attracted widespread attention field. In this review, we focus on physicochemical characteristics GO, CS, GO/CS composites, as well research DDS types based GO/CS.
A new recyclable basic ionic liquid was introduced as an efficient catalyst for aldol condensation and transesterification reactions under environmentally friendly conditions. The prepared based on methyl imidazolium moieties bearing hydroxide counter anions via the Hofmann elimination a 1,3,5-triazine framework. with two functionalities including anion stabilizer high basicity, used well reaction of variety alkyl benzoates. All were performed in absence any external reagent, co-catalyst, or...

Abstract The UV-Vis absorption and fluorescence spectra of proanthocyanidins at different pH values were studied, the change peak position was analyzed. intermediate stable states in conditions, electron transition modes emission these steady Eight parts proanthocyanidins, each with mass 1.00 mg, added to acetic acid buffer solution turn. samples same concentration measured by UV-visible spectrophotometer spectrophotometer, spectrogram analysis carried out. wavelength did not obviously...
Abstract At present, the research on fluorescent molecular probe has become a hot topic in field of environmental science, chemical materials, medicine, and other fields. Therefore, detection industrial mercury-containing wastewater (Hg 2+ ) is great significance. In this article, used to detect mercury ions, when compared with traditional method, advantage operation such as effect simplicity evident. The experiments first synthesized rhodamine B derivatives then derivative probes were...
By modifying the structure of pyridoxal phosphate, an "on-off" rhodamine fluorescent probe LPDQ with a new was synthesized. The characterized by infrared spectroscopy and mass spectrometry. characteristics are used, that is spirolactam does not emit fluorescence in state closed ring. When ring opened when it reacts specific metal, whole system color solution will change. LPDQ-Zn2+ has been successfully constructed characteristic absorption peaks ultraviolet spectrum, experiments carried out...
The production and abuse of fluoroquinolones have caused enormous environmental pollution, there is an urgent need for a simple efficient method to solve this problem. In paper, rare earth lanthanum doped nanocomposite catalyst was synthesized. dendritic structure graphite carbon nitride (g-C3N4) can better wrap polypyrrole (PPy) titanium dioxide (TiO2). surface morphology the composite material has been significantly changed. doping (La) promote electron hole separation inhibit its...
