Abstract A series of MCM‐41s with a high copper content were synthesized at room temperature from sodium metasilicate (Na 2 SiO 3 ) as the silicon source, tetraamminecopper( II nitrate [Cu(NH 4 (NO ] source and cetyltrimethylammonium bromide (CTABr) template. The resulting material was characterized by using following characterization techniques: X‐ray diffraction (XRD), N ‐adsorption isotherms, high‐resolution transmission electron microscopy (HRTEM), inductively coupled plasma (ICP),...
The sol‐gel synthesis technique has been used to produce barium ferrite particles. Several methods such as X‐ray diffractometry, transmission electron microscopy, and magnetism measurement (VSM) have obtain detailed information on the crystallography magnetic properties of precursor calcined correlation BaFe 12 O 19 formation with thermal treatment studied. optimum conditions for preparing nanoparticles at a low calcining temperature are reported, homogeneous ultrafine almost‐ideal...
A simple microwave solid-state reactor was designed on the basis of a domestic oven by using graphite powder as heating medium. The behavior studied an on-line computer to monitor real-time temperature during irradiation. It found that (T) related time (t) and power depended duty cycle (x) Two empirical equations were proposed could be applied similar reactors. Four inorganic layered materials, LiV3O8, KNb3O8, KTiNbO5, KSr2Nb3O10, successfully synthesized in at suitable rate fully controlled...
A novel mesoporous iron phosphate, possessing a specific surface area of 254 m2 g−1 and average pore diameter 2.6 nm, is synthesized using fluoride route.
Fe-B, Fe-Ni-B, and Ni-B ultrafine alloy particles have been prepared by reduction of metal ions in aqueous solution with borohydride. It is shown that iron nickel contents the can be easily varied changing Ni/(Ni+Fe) ratio solution; however, boron content constant when concentration borohydride kept constant. Several experimental results show are amorphous. The scanning electron microscopic image indicates surface morphology Fe35Ni15B26 looks like cotton clusters. From high-resolution image,...
A novel nanocomposite, PEO–LiV3O8, was synthesized by the intercalation of poly(ethylene) oxide (PEO) into interlayers LiV3O8 in one step. It found that two different components were combined on nano-scale; insertion polymer topotactic and did not cause structural changes layered host. The single-step weight loss (11.8 wt%) with TG/DSC measurement other characterization results from XRD, FTIR, Raman, SEM, TEM revealed putative molecular structure PEO within layers similar to zig-zag Type-I...
Semiconductor devices are currently one of the most common energy consumption devices. Significantly reducing semiconductor with advanced energy-efficient technologies is highly desirable. The discovery super-semiconductors (SSCs) based on metallic bi-layer shell arrays provides an opportunity to realize ultra-low-power As example, achievement near zero-threshold voltage in p-n junction diodes super-semiconducting nanostructured Ag/Al reported, realizing diodes: ≈3 W per trillion a working 1...
A series of mesostructured Cu-SiO2 composites have been synthesized with sodium metasilicate (Na2SiO3) and cuprammonia nitrate (Cu(NH3)4(NO3)2) respectively used as Si Cu sources. The synthetic procedures were conducted at room temperature, cetyltrimethylammonia bromide was a template. Under our experimental conditions, ordered mesoporous could be obtained copper content up to 16.8 wt %. Average pore diameters (2.80-3.15 nm), wall thickness (1.30-2.20 specific surface area (1020-690 m2/g)...
A series of alumina-pillared layered tetratitanates with different Interlayer spacings (d001= 15.2–17.0 Å) has been first prepared through a step-wise exchange process and by finely changing the reaction conditions such as time molar ratio reactants in mixture, hydrolysis pH aging used to generate pillaring agent.
