We describe the synthesis, characterization and catalytic properties of a series of hybrid materials composed of inorganic plasmonic mono- and bimetallic nanoparticles supported on organic bio-based hydrogel beads. The bimetallic materials showed a localized surface plasmon resonance in the visible region, with a maximum light absorption correlated to the metal composition of the alloyed systems.

We propose a novel approach relied on high-resolution solid-state 13C NMR spectroscopy to quantify the crystallinity index of chitosans (Ch) prepared with variable average degrees of acetylation (DA) from 5% to 60 % and average weight molecular weight (Mw) ranged in 0.15 × 106 g mol− 1 –1.2 × 106 g mol− 1 .

Article "The correlation between assessment and teaching in students’ English language proficiency" perspectives on the importance of giving an appropriate assessment based on curriculum content and individual capacity for effectiveness in students’ English using. To achieve language proficiency goals, it is more important to find out strengths and weaknesses that arise from each individual student rather than basing on those of large numbers of students.

The study "Estimation of the electrical characteristics of PIN diode after Proton-Irradiated based on Monte carlo code" describes the correlation between radiation damages and electrical properties of the PIN diode after irradiation of the energy proton. The findings show that the penetration of protons into the PN diode leads to lattice defects in the form of vacancies, defect clusters, and dislocations.

Many materials used in a wide range of fields consist of polymers that feature great structural complexity. One particularly suitable technique for characterising these complex polymers, that often feature correlated distributions in e.g. microstructure, chemical composition, or molecular weight, is comprehensive two-dimensional liquid chromatography (LC × LC).

Comprehensive two-dimensional liquid chromatography (LC × LC) is an attractive separation technique that allows achieving high peak capacities and information on chemical correlations. Unfortunately, its application in industrial practice is still not widespread due to limiting factors such as complex method development, tedious method optimization and solvent-incompatibility.

The Tohoku earthquake (Mw9.0) occurred on March 11, 2011 and caused a large tsunami. The Fukushima Daiichi Nuclear Power Plant with six units were overwhelmed by the tsunami and core damage occurred. Authors proposed the concept and method for evaluating core damage frequency (CDF) considering failure correlation at the multi units and sites.

Helium is relevant in determining nuclear fuel behaviour. It affects the performance of nuclear fuel both in reactor and in storage conditions. Helium becomes important in reactor conditions when high burnups are targeted or MOX fuel is used, whereas for storage conditions it can represent a threat to the fuel rods integrity.

Helium plays an important role in determining nuclear fuel performance both in-pile (especially for MOX fuels and those at high burnup) and in storage conditions. Predictive models of helium behaviour are therefore a fundamental element in fuel performance codes.

Tephras are significant markers in the stratigraphic record and play a key role in establishing paleoenvironmental and paleoclimate histories worldwide. Despite burgeoning research focused on tephra characterization and correlation techniques, there are still few techniques that allow for the direct dating of tephra, particularly below the lower age limit of K/Ar and Ar/Ar dating methods.

The present work reports an extended study of anomalous fading (AF) in the TL signal of ten different pure Kfeldspar samples from North Greece. A fading protocol was applied, including a standard series of TL measurements undertaken following a variety of storage times after irradiation, in order to plot the luminescence output as a function of storage time.

The 31P MAS NMR spectra of phosphorus-modified chabazite (P-CHA) zeolites have been observed during the hydrothermal treatment to probe the structural changes of phosphorus species in zeolites. Characteristic changes of the spectra were observed in the range of 27 ~ 42 ppm, which correlates to the hydrothermal structure changes in P-CHA zeolite

In this study, we present a method for all-optical image compression using all-optical Karhunen-Loeve transform (KLT). The KLT was designed in all-optical domain using only one multimode interference (MMI) coupler. The Karhunen-Loeve transform (KLT) is very attractive for image processing applicaons due to its computing efficiency, residual correlation, and rate distortion criteria benefits.

Data processing for obtaining global velocity fields is important in fluid mechanics. This study presents a hybrid algorithm for extracting velocity vectors from particle image velocimetry (PIV) images, which were taken during the experimental process. The hybrid method used both cross-correlation and optical-flow algorithms.
