Knowing a quantum system's environment is critical for its practical use as a quantum device. Qubit sensors can reconstruct the noise spectral density of a classical bath, provided long enough coherence time. Here we present a protocol that can unravel the characteristics of a more complex environment, comprising both…
Heterogeneous nucleation of the $\ensuremath{\alpha}$ to $\ensuremath{\beta}$ phase transition at ${\ensuremath{\langle}1\phantom{\rule{4pt}{0ex}}1\phantom{\rule{4pt}{0ex}}1\ensuremath{\rangle}}_{\ensuremath{\beta}}$-type screw dislocations in pure titanium is examined through a combination of elasticity theory and mo…
Fibrillar materials have gained much attention recently because of their unique properties and potential applications. Although many methods have been developed to fabricate materials, it remains challenging to prepare fibrillar materials containing multicomponent materials or even with complex structures. Here, a fac…
Ceramics with perovskite structure and composition BaCe x Ti 1− x O 3 ( x = 0.02–0.30) show a progressive evolution with increasing x , from the long-range polar order of ferroelectric BaTiO 3 to the short-range polar order typical of relaxors. The ionic size mismatch between Ti 4+ and Ce 4+ determines strong local st…
In this work, the self-assembled morphologies obtained for poly(styrene-b-butadiene-b-styrene) (SBS) and poly(styrene-b-isoprene-b-styrene) (SIS) ABA-type copolymers were investigated before and after hydrogenation of the polydiene block, which led to poly(styrene-b-ethylene)/poly(ethylene-b-styrene) (SEES) and poly(s…
Halo-organic acids in aqueous solutions are widespread pollutants. An enormous number of technologies have been proposed for their elimination. In this context, reducing electron exchange columns seem to be an optimal solution for their degradation, as they do not introduce any new chemical into the solution to be pur…
Abstract In the present study, europium (III) oxide (Eu 2 O 3 )‐doped polystyrene (PS) polymer films were synthesized using a solution‐casting technique for different filler levels. These films were irradiated with 5, 25 and 50 kGy γ doses and characterized using various techniques, viz. X‐ray diffraction (XRD), and U…
The fast and precise direct-printing of micro three-dimensional (3D) structures is the important development trend for micro/nano fabrication technique. A novel method with probe arrays was built up to realize the controllable deposition of 3D electrospun nanofibrous structures. Firstly, several 3D nanofibrous structu…
Silver nanoparticles (AgNPs) were synthesized from aqueous AgNO3 precursor via an effective and ecofriendly method using Lemon Citrus Latifolia (LCL) extract as the reducing and stabilizing agent under sunlight condition. The AgNPs formation was confirmed by ultraviolet-visible absorption spectroscopy at the wavelengt…
We have investigated the magnetic properties of λ-(BEDT-STF)2FeCl4 by Mössbauer measurement to reveal the origin of the paramagnetic-like behavior of the 3d spin system observed in λ-(BETS)2FeCl4 using the donor substitution effect. We found that the temperature dependence of the hyperfine fields shows multistep devel…
Abstract A series of BODIPY cored dendrimers up to second generation decorated with 3,6‐ditertiary butyl carbazole at the surface and triazole as the bridging unit has been achieved by convergent approach. The synthesised dendrimers show excellent photophysical and electrochemical properties. All the dendrimers exhibi…
The distortion/interaction-activation strain model (D/I-ASM), a fragment analysis method, is applied to study the structure-reactivity relationship in reactions. The application of D/I-ASM involves the generation of input files for points along a reaction profile, submission of input files to a quantum software packag…
Abstract The evaluation of the nanoparticles interactions with blood plasma enables a first and important insight on the organization of the adsorbed protein layer. In this context, we studied the formation of protein corona on magneto‐luminescent Fe 3 O 4 @calix‐Eu(TTA) nanoparticles in human plasma. The difference i…
In this paper, a mechanistic model for nanobeams with surface energy effects is developed by using a variational formulation. This work is motivated by the unusual response of nanocantilevers predicted by models based on the Young-Laplace equation for surface stress. The governing equation and boundary conditions deri…
INTRODUCTION: Concerns have been raised regarding occupational exposure to engineered nanomaterials (ENMs). Potential impacts on lung function from inhalation exposures are of concern as the lung is a sensitive ENM target in animals. Epidemiological data suggest that occupational exposure to ENMs may impact respirator…
The proven reliability of ceramic cap-and-pin insulators for high voltage (HV) and extra-high voltage (EHV) overhead lines suffers in the presence of harsh industrial or strong salt pollution [1]. In these cases, apart from the countermeasures such as increasing creepage distance, washing, and applying greases, insula…
Immobilizing enzymes on solid support materials is of great interest for many applications as it improves enzyme lifetime and enables its recycling. Synthetic mesoporous silica materials are widely used as supports for enzyme immobilization due to their high enzyme-loading capacity and their excellent mass transport p…
Abstract Corrosion remains the major reason for the failure of metallic parts. Therefore, spotting and evaluating the severity of corrosion at its early stages is of great importance. Herein, a novel optical corrosion probe based on plasmonic gold nanoparticles immobilized on aluminum surface is demonstrated. The meas…
The ferroelectric–paraelectric transitions of 1,4-diazabicyclo[2.2.2]octane (dabco) tetrafluoroborate (dabcoHBF 4 ) and perchlorate (dabcoHClO 4 ), between their phases II (orthorhombic space group Pm 2 1 n ) and I (tetragonal space group P 4/ nmm ) proceed at T C = 377 and 378 K, respectively. On approaching phase I…
The distribution of the lap-shear strength developed at an amorphous asymmetric compatible interface between the contacting thick (bulk) films of entangled polystyrene (PS) with its miscible blend with poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) (75 wt.% PS and 25 wt.% PPO) at a constant healing temperature (T) of 90…
