A global method for handling fluorescence spectra at high concentration derived from the competition between emission and absorption of colloidal CdTe quantum dots
We investigate the effects of the concentration of CdTe quantum dots (QDs) on their fluorescence in water. The emission spectra, acquired in right angle geometry, exhibit highly variable shapes. The measurements evidence a critical value of the concentration beyond which the intensity and the spectral bandwidth decrea…
Comparison of the exergy efficiency of four power generation systems from methane using fuel cells
Exergy analyses on four solid oxide fuel cell (SOFC) systems using methane as the original fuel are conducted.
Photoswitchable chromic behavior of conjugated polymer films for reversible patterning and construction of a logic gate
Photoswitchable fluorescent films were constructed using a conjugated polymer as a fluorescence-color changeable unit and a photochromic molecule as a phototriggered, selectively energy-accepting component.
Growth of two-dimensional rhenium disulfide (ReS 2 ) nanosheets with a few layers at low temperature
Single-crystalline ReS <sub>2</sub> nanosheets with a few layers were vertically grown on a SiO <sub>2</sub> /Si wafer by a gas phase reaction process at ambient pressure.
Structural properties and strain engineering of a BeB 2 monolayer from first-principles
Using crystal structure prediction and first-principles calculations, we investigated new phases of BeB <sub>2</sub> monolayers and discussed their structural, electronic and strain effect properties of such boron-based 2D materials.
Coordination polymer-derived nano-sized zinc ferrite with excellent performance in nitro-explosive detection
exhibits a strong emission at 402 nm upon excitation at 310 nm. This emissive property was employed for luminescence-based detection of nitroaromatic explosives in an aqueous medium through luminescence quenching for the first time. Importantly, selective detections have been observed for phenolic nitroaromatics based…
Biomimetic intrafibrillar silicification of collagen fibrils through a one-step collagen self-assembly/silicification approach
Intrafibrillar silicified collagen fibrils are successfully fabricated using a one-step collagen self-assembly/silicification approach, which better support osteoblast activities.
Mechanical characterization of glass fiber (woven roving/chopped strand mat E-glass fiber) reinforced polyester composites
Polymer reinforced composites have been replacing most of the engineering material and their applications become more and more day by day. Polymer composites have been analyzing from past thirty five years for their betterment for adapting more applications. This paper aims at the mechanical properties of polyester re…
Epoxidation of 1-octene under harsh tail-end conditions in a flow reactor I: a comparative study of crystalline vs. amorphous catalysts
The crystalline Ti-UCB-4 epoxidation catalyst is more active, selective, and stable than the amorphous Ti–SiO <sub>2</sub> .
New organic–inorganic hybrid compounds based on [SiNb 12 V 2 O 42 ] 12− with high catalytic activity for styrene epoxidation
A series of new organic–inorganic hybrid compounds based on [SiNb <sub>12</sub> V <sub>2</sub> O <sub>42</sub> ] <sup>12−</sup> have been obtained under hydrothermal conditions and characterized by IR, XRD, and single crystal X-ray diffraction analysis.

A label-free and simple fluorescence nanosensor for the determination of adrenaline based on graphene quantum dots.
Inhibition of Bicarbonate-Chloride Corrosion and Passivation of Carbon Steel under Open-Circuit Conditions by Molybdate
Molybdate's inhibition of localized corrosion and passivation of AISI 1020 carbon steel in pH 9 and pH 10 solutions containing bicarbonate/carbonate and chloride anions was investigated under open-circuit conditions. The critical molybdate concentration required to prevent pitting corrosion in these solutions was dete…
A Direct Measurement of the Activation Potential of Stainless Steels in Nitric Acid
The rate of anodic dissolution and the associated activation potential that characterizes the passive-active transition of stainless steels have been measured directly for the first time in nitric acid. The anodic dissolution current under cathodic polarization in pure nitric acid, in absence of chlorides, is masked b…
