in this paper, nickel oxide (nio) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(ii) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(ii) chloride, [nil]cl2, in an electrical furnace at optimal temperature, 450 ºc for 3.5 h. the nickel(ii) complex is obtained via solid state synthesis using nickel(ii) chloride and tetradentate o4 acyclic ligan...

context:in this review, we discuss empirical and stoichiometric models, which have been developed recently in ssf processes and the influence of environmental conditions on the variables of these models. additionally, new studies on modeling of product formation are also mentioned. evidence acquisition:solid-state fermentation (ssf) is recognized as a cheap process for producing many valuable p...

Metal–organic frameworks (MOFs) have gained a large amount of interest because their periodic and modular structure. These features allow easy prediction the physical chemical properties an organic chromophore, acting as linker in MOF. In present work, bianthryl (BA) equipped with metal-coordinating carboxylate groups, is studied to construct photoluminescent Zn-BA surface-anchored MOF (SURMOF)...

The formation of nonluminescent aggregates of aluminium sulfonated phthalocyanine in complexes with CdSe/ZnS quantum dots causes a decrease of the intracomplex energy transfer efficiency with increasing phthalocyanine concentration. This was confirmed by steady-state absorption and photoluminescent spectroscopy. A corresponding physical model was developed that describes well the experimental d...

ZnO/activated carbon nanocomposites (ZnO/ACns) were synthesized by applying two different solid-state and precipitation methods. Precipitation method was initiated with zinc chloride and sodium hydroxide as starting materials in the presence of activated carbon. The synthesized sample was calcined at 250 °C for 1 h. The preparation of nanocomposite by solid-state method was accomplished by heat...

Ozone (O3) gas is widely used as a strong oxidizing agent for many purposes, such as the decomposition/removal of organic contaminants and photoresist, and the deodorization/disinfection of air and water. However, ozone is highly toxic to the human body when the air concentration exceeds about 1 ppm. Therefore, there is increasing demand for simple, sensitive, reliable, and cost-effective techn...

Photoluminescent strips forming a Low Location Lighting (LLL) system are the primary method for marking escape routes on passenger ships. The LLL can be built as self-luminous (powered by electricity) or made series of photoluminescent materials, which glow and indicate route after loss basic emergency lighting. To ensure correct visual guidance, these must installed at specific locations in pa...

Received 25 October 1991 . Abstract. Solid state lasers have undergone a renaissance since the development of reliable and cheap laser diodes which can be used as pump sources. The result is compact, eflicient laser sources which are attractive for a wide range of applications. This review summarizes the properties of laser diodes which are advantageous for pumping solid state lasers and descri...
