Abstract The in situ observation of Au dot formation and the self-assembly dynamics of Au nanoparticles (NPs) was successfully demonstrated via dewetting of Au thin films on SiO 2 glass substrates under nano-second pulsed laser irradiation using a multi-quantum beam high-voltage electron microscope. Moreover, using el…
The rose petal effect (large apparent contact angles accompanied by high affinity to water) has greatly inspired researchers recently. In this paper, the rose-petal surfaces with tunable high water adhesion have been prepared successfully via a facile electroless galvanic deposition process as well as the subsequent m…
This paper presents the development of a novel thermal ink-jet printer head prototype using full carbon-based microbubble generators with carbon nanotubes as heating elements and graphene as electrodes. Meanwhile, each microbubble generator is equipped with a carbon nanotube sensor to real-timely probe the temperature…
The texture of recrystallized straight-rolled α-uranium foils, a component in prospective irradiation target designs for medical isotope production, has been measured by neutron diffraction, as well as X-ray diffraction using both Cu and Mo sources. Variations in the penetration depth of neutron and X-ray radiation al…
Abstract Au/CeO 2 hollow nanospheres were successfully synthesized by template method. Carbon spheres ( CS s) were employed as the sacrificial templates, which were fabricated by hydrothermal method, and the shell of CeO 2 precursor was formed on the surface of CS s through layer‐by‐layer self‐assembled approach. Then…
There are various reasons by which the damage in the cold rolling mill rolls occurs. The main objective is to highlight those reasons which are responsible for the breakage. The parameters considered during the manufacturing and during the regular use of rolls in cold rolling in the past researches and the effect of t…
Triose sugar, 1,3-dihydroxy acetone (DHA) on treatment with Fenton’s reagent releases CO under physiological conditions. The release of CO has been demonstrated by myoglobin assay and quantum chemical studies. The mechanistic study has been carried out using B3LYP/6-311++G(d,p), M06-2X/6-311++G(d,p) and CCSD(T)//M06-2…
Abstract We herein report the design and synthesis of Cs‐symmetric donor–acceptor (D–A) molecular systems that have electron‐donating and electron‐withdrawing groups of the type D‐π‐A‐π‐D and D‐A1‐A‐A1‐D by using a Pd‐catalyzed Sonogshira cross‐coupling and [2+2] cycloaddition–retroelectrocyclization reactions. The ph…
It is proposed that the local electro-explosion is the main cause of rail groove formation on rail surface in this paper. The primary current paths between rails and armature are around the armature edges or corners. The liquid metal film formed on armature-rail interface is produced by electric heating and friction h…
The technological implementation of STT-magnetic random-access memory (MRAM) in real devices needs a complete description of the statistical switching behavior at room temperature. In this paper, we investigate, by means of a full micromagnetic model, the effect of the interfacial Dzyaloshinskii-Moriya interaction (ID…
Human thymidylate synthase (hTS) provides the solede novointracellular source of thymidine 5′-monophosphate (dTMP). hTS is required for DNA replication prior to cell division, making it an attractive target for anticancer chemotherapy and drug discovery. hTS binds 2′-deoxyuridine 5′-monophosphate (dUMP) and the folate…
ABSTRACT The probiotic bacterium Lactococcus garvieae A1, isolated from soil, is interesting for biomining applications. Here, we report the draft genome sequence and annotation of this strain, with a focus on metal transporter enzymes.
The study describes a targeted synthesis of a new dielectric material for an emerging ULTCC-I technology (ultralow temperature co-fired ceramic technology), which resulted in discovery of a PbTeV 2 O 8 phase. A structural solution from powder data showed that the phase belongs to no known crystallographic family and i…
Abstract Harvesting the properties of nanosheets is not only crucial from a fundamental perspective, but also for the development of novel functional devices based on 2D nanosheets. Herein, we demonstrate the processing of organically modified TBAxH1−xCa2Nb3O10 nanosheets into photonic thin films and study their color…
The undoped and B-doped polycrystalline diamond thin film was synthesized by hot filament chemical vapor deposition and microwave plasma, respectively. The structural characterization was performed by scanning electron microscopy, X-ray diffraction and Raman spectroscopy. The electrical properties of synthesized diamo…
This article presents the results of research on multi-layered heterostructures by a modified calculation technique of multiple X-ray diffraction. The Al x In1−x Sb heterostructure and a Zn(Mn)Se/GaAs(001) multi-layered system were used as models to specify conditions for cases of coincidental coplanar three-beam or c…
Mammalian phenylalanine hydroxylase (PAH) is a key enzyme in l‐phenylalanine (l‐Phe) metabolism and is active as a homotetramer. Biochemical and biophysical work has demonstrated that it cycles between two states with a variably low and a high activity, and that the substrate l‐Phe is the key player in this transition…
The methyl viologen dication, used under the name Paraquat as an agricultural reagent, is a well-known electron-acceptor species that can participate in charge-transfer (CT) interactions. The determination of the crystal structure of this species is important for accessing the CT interaction and CT-based properties. T…
Despite their potential, thin film thermionic emitters are yet to appear in real device applications. The main shortcoming for thin film thermionic emitters is their weak emission capability as compared to conventional thermionic cathodes. In this study, a high performance thin film thermionic emitter with emission ca…
Abstract Experiments on graphene growth through chemical vapor deposition (CVD) involving methane (CH 4 ) and hydrogen (H 2 ) gases reveal a complex shape evolution and a non-monotonic dependence on the partial pressure of H 2 ( p H 2 ). To explain these intriguing observations, we develop a microkinetic model for the…
