"In this work we present a solid phase extraction (SPE) flow through system coupled to graphite furnace atomic absorption spectrometry (GFAAS) for the determination of Cd(II) at ultratrace levels. The flow system holds a...

Understanding how laser pulses compress solids into high-energy-density states requires diagnostics that simultaneously resolve macroscopic geometry and nanometer-scale structure. Here we present a combined X-ray imaging...

Recent extensions of the DMol3 local orbital density functional method for band structure calculations of insulating and metallic solids are described. Furthermore the method for calculating semilocal pseudopotential mat...

Popular modern generalized gradient approximations are biased toward the description of free-atom energies. Restoration of the first-principles gradient expansion for exchange over a wide range of density gradients elimi...

Abstract In the course of an investigation of the effect of surface scratches on the mechanical strength of solids, some general conclusions were reached which appear to have a direct bearing on the problem of rupture, f...

The term ``sensitized luminescence'' in crystalline phosphors refers to the phenomenon whereby an impurity (activator, or emitter) is enabled to luminesce upon the absorption of light in a different type of center (sensi...

Generalized gradient approximations (GGA's) seek to improve upon the accuracy of the local-spin-density (LSD) approximation in electronic-structure calculations. Perdew and Wang have developed a GGA based on real-space c...

Soursop is an exotic tropical fruit, highly perishable, presents losses around 30% in postharvest, has marked commercial importance especially for internal consumption and a maximum shelf life. The objective of the prese...

Ca2+ and Si2+ treatments confer resistance to biotic and abiotic stresses in many fruits. In sweet cherries, Ca2+ improves shelf life extension during storage, but only CaCl2 is used. On the other hand, there is scarce i...

To estimate genetic and environmental effects on traits associated with garlic (Allium sativum L.) functional value and postharvest quality, the content of total organosulfur compounds, phenolics, and solids were determi...

The interest in the consumption of edible flowers has increased since they represent a rich source of bioactive compounds, which are significantly beneficial to human health. The objective of this research was to access ...

In this study, biological and chemical pollutants from various points of Diyala River (wastewater, sewage, orchard water, running water, and liquefied water) were treated by synthesizing silver nanoparticles (Ag NPs) by ...

The classical micropolar constitutive theory is reformulated within the framework of the microplane concept in order to obtain constitutive equations and models including available and, hopefully, more precise informatio...

Charge-trapping defects in crystalline solids play important roles in applications ranging from microelectronics, optical storage, sensing and quantum technologies. On one hand, depleting trapped charges in the host matr...

Abstract Molecular single-source precursors are a promising way of obtaining multi-element extended solids directly. We show that thermal decomposition of well-defined mono-, bi- and trimetallic polyoxovanadates (POVs) p...

One of the challenges in preparing MSG raw materials is the reduction in the quality of molasses due to changes in the sugar production process. This research aims to evaluate the impact of adding coagulants on improving...

Supported ruthenium catalysts have been shown to be effective for the dry reforming of methane.Besides, ETS-10 titanosilicate has properties able to disperse Ru species. In this work,  microporous ETS-10 titanosilicate ...

ZnAlFe mixed metal oxides (ZnAlFe-MMOs) were synthesized from layered double hydroxides (LDHs) preparedby the coprecipitation method at pH 9 using an initial weight composition of Zn2+ = 75%, Al3+ = 15% and Fe3+= 10%, wi...

Abstract Soil microbes are essential for ecosystem functioning, affecting soil health and fertility. The microbial diversity present in soil is influenced by diverse land-use practices and environmental conditions; howev...
