two-component reaction of 2-aminobenzophenones with acetylenic esters in the presence of γ-al2o3 and cu/zno as suitable heterogeneous catalysts has been studied. nano γ-al2o3 and cu/zno showed high activities when used as surface catalysts for the synthesis of quinoline derivatives. after completion of the reaction, the catalyst was recovered and reused several times under the same reaction con...

A new efficient method for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones and spiroquinazolinones via a condensation reaction of aldehydes and ketones with anthranilamide in the presence of nano Fe3O4@SiO2-SO3H as catalyst in ethanol has been described. The reactions are completed in short times, and the corresponding dihydroquinazolinones are produced with high yields. The present procedure...

There is a growing attention to enhance the performance of solid oxide fuel cell (SOFC) electrodes through incorporation nano-catalyst materials within electrodes’ active sites. In this study, we report technique for increased efficiency and microstructural control infiltration process polymerized norepinephrine (pNE) treatment. Nano-CeO2 catalysts were incorporated both commercial anode-suppor...

The tunable transformation of renewable furfural with aliphatic alcohols in the presence of O2 is developed. Based on a nano Au catalyst and potassium carbonate, a 91.8% yield of methyl 2-furoate with 98.7% selectivity is obtained via the oxidative esterification in a furfural-methanol-O2 system; while a 91.4% yield of 3-(furan-2-yl-)-2-methylacrylaldehyde with 97.2% selectivity is attained via...

A high-throughput screening (HTS) method based on fluorescence imaging (FI) was implemented to evaluate the catalytic performance of selenide-modified nano-TiO2. Chemical ink-jet printing (IJP) technology was reformed to fabricate a catalyst library comprising 1405 (Ni(a)Cu(b)Cd(c)Ce(d)In(e)Y(f))Se(x)/TiO2 (M6Se/Ti) composite photocatalysts. Nineteen M6Se/Tis were screened out from the 1405 can...

The direct synthesis of TiN nanoparticles on carbon black (CB) was achieved using an mpg-C(3)N(4)/CB composite as a template. The obtained TiN/CB composites ensured improved contact between TiN and CB, functioning as an efficient cathode catalyst for oxygen reduction reaction (ORR) in polymer electrolyte fuel cells (PEFCs). The preparation procedure developed in this study is applicable for the...

The aim of the study is to open a new scope for organic electrochemical transistors based on PEDOT:PSS, a material blend known for its stability and reliability. These devices can leverage molecular electrocatalysis by incorporating small amounts of nano-catalyst during the transistor manufacturing (spin coating). This methodology is very simple to implement using the know-how of nanochemistry ...

An efficient and rapid method for the synthesis of 3,4,5-substituted furan-2 (5H)-ones has been achieved through a three-component reaction of aniline, dialkyl acetylenedicarboxylate, and aromatic aldehydes using nano-colloidal silica-tethered polyhedral oligomeric silsesquioxanes with eight branches of 3-aminopropyltriethoxysilane (nano-colloidal silica @APTPOSS) as a superior catalyst under m...

 In this work, Fe/TiO2 nanostructured catalyst was prepared using sol-gel method developed by Yoldas and tested in degradation of phenol in water under UV radiation.  The synthesized catalyst was characterized by XRF, XRD, specific surface area and porosimetry, and SEM methods. The porosimetry revealed the mesopore structure of the catalyst. Results of SEM confirmed the nano dispersion of  iron...

Cell-penetrating peptides (CPPs) are short 8-30 amino-acid oligopeptides that act as effective transducers of macromolecular cargo, particularly nucleic acids. They have been implemented in delivering dsDNA, ssDNA, and dsRNA into animal and plant cells. CPPs and nucleic acids form nano-complexes that are often 100-300 nm in size but still effectively transit the cell membrane of animal cells, b...
