Generating promising materials for the conversion of CO2 to valuable industrial products under mild conditions is important both ameliorating greenhouse effect and sustainable development. Pillar[5]arene-incorporated have recently emerged as building frameworks construct versatile functional polymeric materials. Herein, we demonstrate that highly efficient fixation cyclic carbonates can be achi...

a series of n-substituted-2,4-thiazolidinedione derivatives (tzds) were prepared via n-alkylation of 2,4-tzd at position 3 using substituted benzyl halides. synthesized n-substituted-2,4-tzd was then substituted at position 5 with substituted aromatic aldehyde according to knoevenagel condensation method. structures of the compounds were elucidated using various spectral techniques viz. ir, 1hn...

We demonstrate the kinetically controlled growth of one-dimensional Co nanomagnets with a high lateral order on a nanopatterned Ag(110) surface. First, self-organized Si nanoribbons are formed upon submonolayer condensation of Si on the anisotropic Ag(110) surface. Depending on the growth temperature, individual or regular arrays (with a pitch of 2 nm) of Si nanoribbons can be grown. Next, the ...

We examined the synthesis, physical properties, and resist properties of various iodine-containing molecules polymers as materials. By condensation reaction 2,6-dimethylphenol (DMP) with 4-iodebenzaldehyde (IBA), 3,5-diiodesalicylaldehyde (DISA) 4-hydroxy-3,5-diiodebenzaldehyde (HDIA), corresponding iodine containing compounds DIPM, 2-DIPM, 4-DIPM were synthesized. The these adamantyl bromo ace...

Co@pyr/APTZCMNPs was synthesized, and some of its characteristic analyses, such as Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-ray diffraction (XRD) were investigated. The results indicated that this heterogeneous catalyst was an excellent and reusable system to synthesize of 14H</e...

the nanoparticles of ti and tio2 have attracted extensive research interest because of their diverse applications in, for instance, catalysis, energy conversion, pigment and cosmetic manufacturing and biomedical engineering. through this project, a one-step bulk synthesis method of electromagnetic levitational gas condensation (elgc) was utilized for the synthesis of monodispersed and crystalli...

Mesoporous silicas synthesized by the co-condensation of two and three different silica monomers were varying time intervals between addition individual monomers, while total interval was kept constant. This resulted in structural properties final silicas, particularly their porosity local ordering. One obtained samples exhibited an unusual isotherm with hysteresis loops its pore volume as high...
