Physical properties of out of equilibrium soft materials depend on time as well as deformation history. In this work we propose to transform this major shortcoming into gain by applying controlled deformation field to tailor the rheological properties. We take advantage of the fact that deformation field of a certain…
Bioengineered vascular grafts provide a promising alternative to autografts for replacing diseased or damaged arteries, but necessitate scaffold designs capable of supporting a confluent endothelium that resists endothelial cell (EC) detachment under fluid flow. To this end, we investigated whether tuning electrospun…
Nanotechnology has the potential to increase the selectivity and potency of chemical, physical, and biological approaches for eliciting cancer cell death while minimizing collateral toxicity to nonmalignant cells. Materials on the nanoscale are increasingly being targeted to cancer cells with great specificity through…
Incorporating the agents for magnetic resonance imaging (MRI), optical imaging, and therapy in one nanostructured matrix to construct multifunctional nanomedical platform has attracted great attention for simultaneous diagnostic and therapeutic applications. In this work, a facile methodology is developed to construct…
In the present work, we investigated theoretically the linear, nonlinear, and total absorption coefficients and refractive index changes associated with intersubband transitions in ZnO/ZnS core shell quantum dot (CSQD) and ZnS/ZnO inverted CSQD (ICSQD), emphasizing on the influence of the shell thickness, impurity, an…
The creation of three-dimensionally engineered nanoporous architectures via covalently interconnected nanoscale building blocks remains one of the fundamental challenges in nanotechnology. Here we report the synthesis of ordered, stacked macroscopic three-dimensional (3D) solid scaffolds of graphene oxide (GO) fabrica…
We reported a new type of graphene aerogel-nickel foam (GA@NF) hybrid material prepared through a facile two-step approach and explored its energy storage application as a binder-free supercapacitor electrode. By simple freeze-drying and the subsequent thermal annealing of graphene oxide hydrogel-NF hybrid precursor,…
We investigate theoretically the effects of generation and injection of plasmonic carriers from an optically excited metal nanocrystal to a semiconductor contact or to surface molecules. The energy distributions of optically excited hot carriers are dramatically different in metal nanocrystals with large and small siz…
The accurate and reliable prediction of properties of molecules typically requires computationally intensive quantum-chemical calculations. Recently, machine learning techniques applied to ab initio calculations have been proposed as an efficient approach for describing the energies of molecules in their given ground-…
Tuning band energies of semiconductors through strain engineering can significantly enhance their electronic, photonic, and spintronic performances. Although low-dimensional nanostructures are relatively flexible, the reported tunability of the band gap is within 100 meV per 1% strain. It is also challenging to contro…
The development of facile and versatile strategies for thin-film and particle engineering is of immense scientific interest. However, few methods can conformally coat substrates of different composition, size, shape, and structure. We report the one-step coating of various interfaces using coordination complexes of na…
A dc magnetoelectric sensor capable of measuring both dc and ac magnetic fields is developed by combining a thickness-polarized 0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 (PMN–PT) piezoelectric single-crystal plate, a pair of electrically connected aluminum strips, and a pair of NdFeB magnet plates in orthogonal directions. The op…
Abstract Scanning laser vibrometry was used to investigate the mechanical stability of free‐standing micro‐solid oxide fuel cell (micro‐SOFC) membranes. Arrays of square‐shaped 460 nm thin micro‐SOFC membranes were fabricated on silicon substrates using pulsed laser deposition for the yttria‐stabilized zirconia electr…
Abstract Five charge‐transfer salts based on the combination of anionic Fe III and Cu II bis(dithiolene) complexes containing nitrile groups with [M(cyclam)] 2+ (M = Ni, Cu) cations, namely, [Ni(cyclam)] 2 [Cu(dcbdt) 2 ] 2 · 4DMF ( 1 , dcbdt = 4,5‐dicyanobenzene‐1,2‐dithiolate, DMF = N , N ‐dimethylformamide), [Ni(cyc…
A facile and efficient approach is developed for the fabrication of asymmetric non‐spherical polymer particle arrays. A specific amount of solvent is provided to interact with the spherical polymer particles to intensify the segmental mobility, thus suppressing the viscosity and the glass transition temperature of the…
Lead-free piezoelectric ceramics with the composition of (1−x)Bi0.5(Na0.80K0.20)0.5TiO3-x(Ba0.98Nd0.02)TiO3 or (1−x) BNKT-xBNdT (with x = 0–0.20 mol fraction) have been synthesized by a conventional mixed-oxide method. The compositional dependence of phase structure and electrical properties of the ceramics were syste…
We proposed a new approach for estimating the magnetoelectric coefficient of magnetostrictive/piezoelectric composites via finite element analysis. With this method, the relationship between inputting magnetic field and outputting electric polarization for magnetoelectric composites could be directly calculated. This…

Highly efficient magnetic resonance imaging (MRI) probes have been prepared by loading Gd(III) complexes on the surface of solid lipid nanoparticles (pSLNs). Applicability as molecular imaging probes is demonstrated by an in vitro model study with targeted pSLNs.
The dyads 1OFF and 2OFF were prepared by combining the inorganic luminophores [Ru(phen)2(2-[imidazol-2-yl]pyridine)](2+) and [Re(CO)3Cl(2-[imidazol-2-yl]pyridine)] with 2-(anthracen-9-yl)-4-methylphenol as a second photoactive moiety. In both cases, the inorganic unit operates as the emitter, whereas the organic part…
