Donor-acceptor (D-A) polymers have attracted significant scientific interest recently because their electronic and optoelectronic properties can be manipulated through intramolecular charge transfer (ICT). However, the correlation between the chemical structure, morphology, and optoelectronic properties has not been f…
为了解决固体氧化物燃料电池(SOFC)陶瓷连接材料的低成本制备难题, 设计了与LaCrO3基连接材料和Ni基阳极均具有良好烧结匹配性能的新型复合材料NiO/ La0.7Ca0.3Cr0.97O3−δ (LCC97)作为管式SOFC的支撑体. 详细研究了NiO含量(5wt%、25wt%、50wt%、75wt%)对复合支撑体的烧结性能、微观组织、孔隙率、电导性能、热膨胀系数等的影响, 结果表明: LCC97与NiO具有优良的烧结和化学匹配性能, NiO/LCC97(1:1, wt%)具有最优的综合性能. 以其为支撑体, 采用浆料浸渍法制备LCC97湿膜, 1400℃空气条件下共烧, 获得了致密LCC97连接材料薄膜.
In recent years, the demand for alternatives to fossil fuels has risen dramatically, and ethanol fuel has become an important liquid fuel alternative globally. The most efficient mode of transportation of petroleum-based fuel is via pipelines, and due to the 300% increase in ethanol use in the U.S. in the past decade,…
MRI is a powerful technique that is commonly used in clinical settings. It is non-invasive, does not employ ionizing radiation, and is capable of high spatial and temporal resolution, making it ideal for a wide variety of imaging applications, both for active diagnostic applications and preventative medicine. The stra…
Materials selection is a matter of great importance to engineering design and software tools are valuable to inform decisions in product development. When a pool of alternative materials is available for different parts, the question of what optimal material mix to select for a set of parts is not simple. In engineeri…
In this paper we present a discrete a posteriori error estimate for a thermoelastic model problem approximated using the component mode synthesis (CMS) model reduction method. The problem is one-way coupled in the sense that heat transfer affects the elastic deformation, but not vice versa. The error estimate bounds t…
Techniques in the family of weighted residual methods; the orthogonal collocation, Galerkin, tau, and least-squares methods, are adopted to solve a non-linear and highly coupled pellet problem. Based on a residual measure and problem matrix condition numbers, the Galerkin and tau methods are favorable solution techniq…
This paper investigates the effect of interior structures on underwater implosions to mitigate the generated pressure waves. For this purpose a simple spherical implosion with a spherical shell placed inside a bubble is considered. The analytical model couples a finite element model (FEM) for the structural subsystem…
A new finite element is presented for linear magnetoelectric straight laminated beam subject to the assumptions of quasi-steady electromagnetic state. The mechanical model is based upon Timoshenko beam theory to account for shear deformation influences. The electromagnetic stacking sequence is proved to enter the equi…
In the last decade, a number of works have been published proposing the solution of heat diffusion problems by first transforming the relevant partial differential equation (PDE) to the frequency domain. Many of those works make use of the boundary element method, thus requiring the previous knowledge of fundamental s…
In this paper the progressive collapse behaviour of a moment frame with infill steel panels is evaluated using nonlinear static pushdown analysis. The analysis model is a two storey two span structure designed only for gravity load, and the loaddisplacement relationship is obtained with the centre column removed. To o…

Plasmon-coupled fluorescence of rare earth Sm 3+ ions doped into the TiO 2 film placed on thin gold layer is investigated. It was demonstrated that plasmon waves induced in the gold layer strongly influence rare earth emission. We revealed that each spectral peak of Sm 3+ emission can be directionally separated, polar…
Here are shown the results of the studies on the polycondensation of amines and epichlorohydrin to obtain policationits that are effective flocculants for water clarification. The resulting cationic flocculants ensure effective cleaning of natural water and synthetic suspensions
Rayleigh and Mandel'shtam-Brillouin scattering (RMBS) spectroscopy and high temperature ultrasonic study (HTUS) are applied to PbO-Al 2 O 3 -B 2 O 3 glass forming system characterized by over liquidus miscibility gap. Temperature dependences of ultrasonic velocity of glass melts were measured in 600-1200°C range. "Fro…
The paper presents a procedure for mapping large amounts of experimental measurement data in a compact and representable form, preserving information on the properties of the research object for further investigations. The raw data set is compacted using mathematical description of dielectric relaxation. This approach…
Dissipative particle dynamics (DPD) was carried out to study the nucleation and crystal growth process of $CeO_2$ nanoparticles in different alcohol aqueous solutions. The results showed that the nucleation and crystal growth process of $CeO_2$ can be classified into three stages: nuclei growth, crystal stabilization…
Polyaniline (PAni) and other conducting polumers such as PMAS poly 2-methoxyaniline 5-sulfonic acid prepared in acidic media are some of the most widely studied conducting polymers due to their straightforward method of preparation and the stability of their conductive emeraldine salt (ES) form. Many applications have…
Bone loss induced by inflammation is one of the complications after biomaterial implantation. There is no much data on expression of cytokines and defensins into the bone tissue around the implants in literature. The aim of this work was to investigate the distribution and appearance of interleukin (IL)-1, IL-6, IL-8,…
Nanocrystal quantum dots exhibit size-dependent optoelectronic properties and provide intriguing scientific and technological opportunities. Most proposed technologies based nanocrystals depend on macroscopic functional assemblies of nanocrystals in which the nanocrystals interact with each other to give rise to new c…
