Holographic reflection gratings in a polyvinyl alcohol/acrylamide based photopolymer were stored using symmetrical geometry in three different thicknesses of the material. The advantage of symmetrical geometry is that exact expressions for transmittance, reflectance, and electric fields can be obtained analytically. U…
Single scattering particles, especially noble metal (plasmonic) nanoparticles, based analytical techniques are attractive recently and becoming the research focus of the light scattering analytical techniques. In this mini review, we summarize the single scattering particles based analytical techniques in the past dec…
High-yield pulp (HYP) has various fractions, and they not only play an important role in the papermaking process but also affect paper properties. Hence, it is necessary to clarify the impact of different HYP fractions on paper formation and properties. In this study, the characteristics of poplar preconditioning foll…
A novel TiO 2 (anatase) containing a large amount of single electron trapped oxygen vacancies (SETOV) was prepared by dehydration of titanic acid nanotubes. This novel TiO 2 contains high concentration intrinsic defects in bulk structure, while its surface still remains the stoichiometric structure to protect them. An…
The surface of vulcanized ethylene propylene diene terpolymers (EPDM) was modified by Ar and N2, microwave generated plasma in order to improve adhesion properties. Surface modification was characterized by universal attenuated total reflectance Fourier Transform Infrared (UATR/FT-IR), because it presented lower inter…
An in situ synchrotron x-ray absorption measurement was carried out to estimate the density of liquid SnI4. The characteristic densities of the low- and high-pressure liquids were found to be 4.6–4.7 and 4.9–5.0 g/cm3, respectively, and their region is separated at around 1.7 GPa. The difference in density, although a…

In this work, the accuracy of the second-order incremental expansion using the domain-specific basis set approach is tested for 20 cationic metal-aqua and 25 cationic metal-amine complexes. The accuracy of the approach is analysed by the statistical measures range, arithmetic mean, mean absolute deviation, root mean s…
Four new labdane-type diterpenoid glycosides, laevissiosides A-D ( 1 – 4 ) were isolated from the 95% ethanol extract of Diplopterygium laevissimum (Christ) Nakai, along with two known analogues, 18- β -D-glucopyranosyl ester-sclareol ( 5 ) and 18-hydroxy-sclareol ( 6 ). The structures of compounds 1 – 4 were elucidat…
An exact closed-form representation is derived of a vector elegant Laguerre-Gaussian wave packet. Its space-time representation consists of three mutually orthogonal field components--of a common azimuthal index and different radial indices--uniquely distinguished by first three powers of the paraxial parameter. The t…
The electronic structure of TEMPO (2,2,6,6-Tetramethylpiperidine-N-oxyl) and its cation and anion were studied experimentally using the electron spectroscopy techniques, dissociative electron attachment (DEA) spectroscopy, electron energy-loss spectroscopy, measurement of elastic and vibrational excitation (VE) cross…
BACKGROUND: Hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) is used to treat peritoneal surface-spreading malignancies to maximize local drug concentrations while minimizing systemic effects. The pharmacokinetic advantage of HIPEC is defined as the intraperitoneal to intravascular ratio of drug concen…
Activity concentrations of the naturally occurring radionuclides (226)Ra, (232)Th, (40)K and anthropogenic (137)Cs in sand samples collected from 20 renowned beaches on the Coast of Montenegro have been determined using an HPGe (high purity Ge spectrometer). The average activity concentrations were found to be 7.4, 5.…
Abstract The thermal–nonsolvent induced phase separation method was used for the fabrication of porous membranes from polyamide 12 (PA12), an attractive engineering polymer; the water/formic acid (FA)/PA12 ternary system is explored in detail. Scanning electron microscopy, differential scanning calorimetry, X‐ray diff…
Nanobiodevices have been developed to analyze biomolecules and cells for biomedical applications. In this review, we discuss several nanobiodevices used for disease-diagnostic devices, molecular imaging devices, regenerative medicine, and drug-delivery systems and describe the numerous advantages of nanobiodevices, es…
We present the derivation of boundary conditions on a wave function at the normal metal/superconductor (N/S) interface by extending the tight-binding approach developed for semiconducting heterostructures [Phys. Rev. 27 (1983) 3519]. Based on these boundary conditions, we formulate a quantitative theory for tunneling…
Phononic and magnonic dispersions of a linear array of periodic alternating Ni80Fe20 and bottom anti-reflective coating nanostripes on a Si substrate have been measured using Brillouin light scattering. The observed phononic gaps are considerably larger than those of laterally patterned multi-component crystals previo…
Human population growth has led to accumulation of large amount and variety of wastes, which take many decades to degrade and also release toxicity during degradation. A sustainable solution is required to treat these wastes to prevent our future population from environmental hazards. Recently, microbial fuel cell (MF…
On-board hydrogen storage remains a challenge to validate hydrogen fuel cells for transport applications. Ammonium bicarbonate is widely used as low-cost fertilizer in farms. Solid NH 4 HCO 3 and (NH 4 ) 2 CO 3 contains high weight percentage of hydrogen and are potential on-board hydrogen storage materials. The use o…
Nitrogen oxides (NOx) are the cause of severe environmental problems such as acid rain, smog formation, an increase in ground-level ozone, depletion of the ozone layer, and global warming and can indirectly affect human and animal health. Considering its severe polluting aspects, many approaches have been utilized so…
