Proteins are often characterized in terms of their primary, secondary, tertiary, and quaternary structure. Algorithms such as define secondary structure of proteins (DSSP) can automatically assign protein secondary structure based on the backbone hydrogen-bonding pattern. However, the assignment of secondary structure…
Bioprinting/3D cell printing procedures for the preparation of scaffolds/implants have the potential to revolutionize regenerative medicine. Besides biocompatibility and biodegradability, the hardness of the scaffold material is of critical importance to allow sufficient mechanical protection and, to the same extent,…
Elastomer-infiltrated vertically aligned carbon nanotube (VACNT) forests are good candidates for use as stretchable conductors that can retain the electrical properties under relatively large stretching. The electrical performance can be further enhanced in terms of high stretchability and small change in the electric…
The vibration behavior of a bridged single walled carbon nanotube with a bio-mass adsorbed at various positions subjected to temperature change is investigated. The frequency equation of the sensor is derived analytically based on nonlocal Euler–Bernoulli beam theory. The relationship between the vibration frequency,…
Azo-modified photosensitive polymers offer the interesting possibility to reshape bulk polymers and thin films by UV-irradiation while being in the solid glassy state. The polymer undergoes considerable mass transport under irradiation with a light interference pattern resulting in the formation of surface relief grat…
The periplasmic enzyme l-asparaginase type II from Escherichia coli (EcAII) converts l-asparagine to l-aspartate and ammonia. EcAII is an important drug in the treatment of childhood acute lymphoblastic leukemia, the most common malignancy in children. Leukemic blast cells lack the ability to synthesize l-asparagine a…
Platinum nanoparticles supported on Ca(Mg)-ZSM-5 is an efficient, highly selective and stable catalyst for room-temperature oxidation of alcohols in water. Based on in situ EPR measurement and the radical trapping technique, we propose that the generation of ˙OH radicals by cleavage of the O-O bond in the H2O2 interme…
Today’s battery powered electric vehicles still face many issues: (1) Ways of improving the regenerative braking energy; (2) how to maximally extend the driving-range of electric vehicles (EVs) and prolong the service life of batteries; (3) how to satisfy the energy requirements of the EVs both in steady and dynamic s…
Recent years there have been observed a wide application of a metalware in industrial and civil engineering. Special place in the building industry is belonged to light steel thin-walled constructions having a lot of technological advantages. In the article the first development cycle of a numerical method creating is…
Earth-abundant, non toxic and cheap Fe2O3 can be used as photocatalyst for sustainable hydrogen production from bio-ethanol aqueous solutions, under sunlight irradiation and without the application of any external electrical bias. To this aim, supported materials are not only technologically more appealing than powder…
We report on novel diblock copolymers of poly(N-vinylcaprolactam) (PVCL) and poly(N-vinyl-2-pyrrolidone) (PVPON) (PVCL-b-PVPON) with well-defined block lengths synthesized by the MADIX/reversible addition-fragmentation chain transfer (RAFT) process. We show that the lower critical solution temperatures (LCST) of the b…
The selection of solvents in the chemical industry is typically based on performance and economic considerations. Other relevant aspects, such as the safety implications of a given solvent, are generally left for consideration after the design of the process has been completed. In this work, an approach for solvent se…
As batteries become more powerful and utilized in diverse applications, thermal management becomes one of the central problems in their application. We report the results on thermal properties of a set of different Li-ion battery electrodes enhanced with multiwalled carbon nanotubes. Our measurements reveal that the h…
Metabolism of molecular oxygen in the human body inevitably produces reactive oxygen species (ROS). Among the family of ROS, those exhibiting very high reactivities, including ˙OH, ˙OOH, ONOO−, HOCl, HOBr, and 1O2, remain relatively underexplored. While emerging evidence suggests that these ROS are critically involved…
A molecular ion (BF4(-)) substituted hybrid perovskite CH3NH3PbI(3-x)(BF4)x is synthesized. The substituted perovskite shows significant enhancement in electrical conductivity at low frequencies and improved photoresponse under AM1.5 illumination as compared to the perovskite (CH3NH3PbI3).
Recently, various metal nanostructures have been introduced into organic solar cells (OSCs) for performance enhancement. Here, we review the recent progress in OSCs incorporated with multiple metal nanostructures including various metal nanopatterns and metal nanomaterials. Multiple physical effects arise from these i…
Controlling the dimensions in the nanometer scale of olivine-type LiFePO4 has been regarded as one of the most effective strategies to improve its electrochemical performance for Li-ion batteries. In this communication, we demonstrate a novel LiFePO4 nanoarchitecture, which is composed of self-assembled single-crystal…
NiS nanosheets on ITO substrates were synthesized with in situ growth via a one-step hydrothermal route, and exhibited an efficiency of 7.08% which was comparable to the solar cell based on the Pt electrode (7.01%) under the similar conditions.
Abstract Non-axisymmetric drops can significantly alter impact dynamics via rebound suppression when compared to axisymmetric drops. In this study, we focus on ellipsoidal drop impact on a non-wetting surface and investigate the effects of the geometric aspect ratio ( $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\m…
Black Nb(4+) self-doped K4Nb6O17 microspheres were prepared for the first time through a facile UV light photoreduction method. By the introduction of Nb(4+), the defective K4Nb6O17 can harvest the full spectrum of visible light as well as near-infrared light. The black K4Nb6O17 microspheres showed improved visible-li…
