Hierarchical assembly of Ti(IV)/Sn(II)-doped SnO₂ nanosheets along titanate nanowires serving as both sacrificial templates and a Ti(IV) source is demonstrated, using SnCl2 as a tin precursor and Sn(II) dopants and NaF as the morphology controlling agent. Excess fluoride inhibits the hydrolysis of SnCl2, promoting het…
Two broad bandgap polymers, poly{(indacenodithieno[3,2-b]thiophene)-alt-[2,5-bis(thiophen-2-yl)thiazolo[5,4-d]thiazole-5,5′-diyl]} PIDTT-TzTz and poly{(indacenodithieno[3,2-b]thiophene)-alt-[2,5-bis(6-octylthieno[3,2-b]thiophen-2-yl)thiazolo[5,4-d]thiazole-5,5′-diyl]} PIDTT-TzTz-TT, were designed and synthesized by co…
The present paper focused on antioxidant and cytotoxicity assessment of crude and total saponin fraction of Chlorophytum borivilianum as an important medicinal plant. In this study, three different antioxidant activities (2,2-diphenyl-1-picrylhydrazyl radical scavenging (DPPH), ferrous ion chelating (FIC), and β -caro…
A hydrothermal reaction of Cu(NO3)2, 1,2-bis(1,2,4-triazol-1-yl)ethane (bte) and 5-sulfoisophthalate (sip) yields an interesting three-dimensional metal–organic framework {[Cu9(OH)6(bte)2(sip)4(H2O)3]·6H2O}n (1). A single-crystal analysis revealed that compound 1 consists of a (3,14)-connected three-dimensional MOF wi…
The conductive polythiophene/chitosan/carboxymethylchitosan (PTH/CS/CMCS) hydrogel were prepared in this study. Polythiophene was synthesized via oxidative polymerization in chloroform at 40 °C. For CMCS synthesis, CS was alkalized with sodium hydroxide in isopropanol and then reacted with monochloroacetic acid at 50…
Turmeric extract (tmr) loaded nanoparticles were prepared by crosslinking modified carboxylmethyl cellulose (CMC) and modified sodium alginate (SA) with calcium ions, in a high pressure homogenizer. The FTIR spectra of CMC and SA were affected by blending due to hydrogen bonding. The negative zeta potential increased…
The Li-Si phase diagram shows the existence of four stable phases [Li 12 Si 7 , Li 7 Si 3 , Li 13 Si 4 and Li 22 Si 5 ]. In addition, Zintl phase LiSi, usually prepared under high temperature-pressure (873 K-4 GPa), has recently been added into the diagram as LiSi is also indeed stable under ambient conditions. A nove…
Long-term creep strength of ASTM/ASME Grade 91 steels was investigated. Two heats of Grade 91 steels indicated lower creep rupture strength than the other four heats from short-term to long-term, and presence of delta ferrite phase was observed. In the short-term, no difference in creep rupture strength was observed a…
为了满足多孔的骨头代用品，的机械、生物的要求，有预先设计的二种不同毛孔尺寸的多孔的 Ti 被空间持有者 sintering 过程制作。多孔的 Ti 的机械性质经由房间温度 compressive~tests 被探索。毛孔尺寸和形状在整个标本是一致的，孔从 36% ～ 63%。压缩力量和有弹性的模量分别地在从 94.05 ～ 468.57 MPa 和 2.662 ～ 18 GPa 的范围。在压缩力量和孔之间的关系是在机械性质上的毛孔尺寸分布的效果以外的完全线性的关系，是值得注意的。从 Gibson-Ashby 模型完成的经常的 C 的价值建议毛孔尺寸影响多孔的 Ti 的收益力量和密度代表(n)的价值因为有二种不同毛孔尺寸的多孔的 T…
Spin coating is an out-of-equilibrium technique for producing polymer films and colloidal crystals quickly and reproducibly. In this review, we present an overview of theoretical and experimental studies of the spin coating of colloidal suspensions. The dynamics of the spin coating process is discussed first, and we p…
Fast response organic photodetectors were developed based on a high mobility hole-transporting organic semiconductor 1,1-bis[(di-4-tolylamino)phenyl]cyclohexane (TAPC). The active layer was constructed by mixing TAPC with a high electron mobility C70 and sandwiched between TAPC and C70. This kind of planar-mixed heter…
The design, synthesis and thiol sensing ability of chromenoquinoline-based fluorescent probes 4, 5 and 6 and are reported here. The relative position of the maleimide moiety was varied along the chromenoquinoline fluorophore to decrease the background fluorescence. Lower background fluorescence in probes 4 and 6 was r…
A new titanium-based sulfide clusterfullerene, Ti2S@D3h(24109)-C78, has been successfully synthesized by arc-discharging graphite rods packed with pure TiO2 and graphite powder under an atmosphere of SO2 and helium. Multistage HPLC methods were utilized to isolate and purify the Ti2S@C78, and mass spectrometric charac…
Highly ordered noncrystalline boron-doped nickel nanotube arrays are rapidly synthesized within 150 s by template-based electroless deposition. The as-prepared nanotubes have tunable magnetic properties and exhibit super efficient catalytic activity (∼70 s) for the reduction of 4-nitrophenol.
Novel carbonaceous support (Starbon) for TiO 2 photocatalysts synthesized by a simple ultrasound-assisted impregnation technique. High phenol photo-oxidation rate to complete mineralization. Renewable materials for a straightforward photocatalysts synthesis.
A straightforward, reduction-free method for the synthesis of organometallic cobalamins has been developed. Stable phenylacetylide derivatives were characterized by X-ray analysis, showing a pronounced influence of the electronic nature of substituents on their structure.
The use of small interfering RNA (siRNA) to silence target genes involved in disease has generated much excitement in the scientific community. While promising, the clinical application of RNA interference (RNAi) is still challenging in achieving effective delivery and tracking of siRNA to target cells. A new multifun…
Structural changes occurring in an Fe(72.5)Cu1Nb2Mo2Si(15.5)B7 alloy during a combination of constant rate heating (20 K min(-1)) and isothermal holding at 500 and 520 °C were investigated using in situ high-energy X-ray diffraction. We found that the ferromagnetic-to-paramagnetic transition of the amorphous phase is…
