A pillar[5]arene-fused cryptand with two different cavities was synthesized successfully. It was found that the novel tricyclic host could associate with two different guest species in an orthogonal manner. And based on this orthogonal self-assembly of two host-guest interactions, a novel type of supramolecular polymer was constructed easily and conveniently.

An N-fused BDOPV derivative, NBDOPV, was designed and synthesized. The photophysical and electrochemical properties of NBDOPV were systematically investigated. The NBDOPV-based conjugated polymer PITET shows a large hole mobility of 1.92 cm(2) V(-1) s(-1).

the :union: of two different dental sprouts which can happen in any phase of dental development is commonly called fusion. this developmental anomaly may cause clinical problems including esthetic impairment, which are mainly treated by endodontic and surgical treatments. there are a few reports of conservative not invasive treatment of fused incisors teeth through restorative or prosthetic tec...

AIM To evaluate the dose-dependent immunogenic properties of poly(lactide-co-glycolide) (PLGA) particles coated with cellobiose as antigen carriers for oral immunization. METHODS Two types of PLGA-cellobiose particles (PLGA-cellobiose-1, ~ 0.8 μm and PLGA-cellobiose-2, ~ 1.2 μm) containing non-toxic recombinant subunit B (SbB) of diphtheria toxin fused with enhanced green fluorescent protein ...

5-6 nm gold nanoparticles were prepared by hydrolytic decomposition of [NMe4][Au(CF3)2] and functionalized in situ with mono- and multivalent thiolated PEG ligands. Time-dependent changes of the nanoparticles were monitored in aqueous NaCl, NaBr, and NaI solutions by UV-Vis spectroscopy, TEM, and HRTEM. The purely sterically protected particles are stable in ≤1 M NaCl and NaBr solutions, regard...

Thin sections of the oocyte periphery and surrounding granulosa layer from 1--5 day preovulatory follicles were examined by transmission electron microscopy. With the use of certain procedures in tissue preparation, notably the tannic acid method, numerous particles in the range of 15--40 nm with a mean diameter of 27 nm were observed in both extra- and intracellularly. The particles were abund...

Recent spatiotemporal report demonstrated that epidermal stem cells have equal potential to divide or differentiate, with no asymmetric cell division observed. Therefore, how epithelial stem cells maintain lifelong stem-cell support still needs to be elucidated. In mouse blood and bone marrow, we found a group of large cells stained strongly for eosin and containing coiled-tubing-like structure...

abstract the aim of this study is laboratory investigation of nitrate reduction in water using fe/cu nano particles. in this regards, nano fe0 (54±4 nm) and fe/cu particles (75±3 nm) was synthesized and characterized by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and transmission electron microscopy (tem) photographs. the effects of coating load of nano-fe0 by cu (0, 5, ...

Fumonisins B1 and B2 are carcinogenic commonly contaminate corn corn-based products. Analysis of such toxins using C18 HPLC column is officially accredited but still unknown if all types can effectively separate FB1 FB2 or not. The present study evaluated the efficiency 5 analytical columns with different dimensions, particle sizes, porosities to determine these in both agar cultures Fusarium v...
