We study theoretically the onset of shear banding in the three most common time-dependent rheological protocols: step stress, finite strain ramp (a limit of which gives a step strain), and shear startup. By means of a linear stability analysis we provide a fluid-universal criterion for the onset of banding for each pr…
Nanostructured three-dimensional constructs combining layer-by-layer technology (LbL) and template leaching were processed and evaluated as possible support structures for cartilage tissue engineering. Multilayered constructs were formed by depositing the polyelectrolytes chitosan (CHT) and chondroitin sulphate (CS) o…
BACKGROUND: Lab studies have suggested that ubiquitous phthalate exposures are related to obesity, but relevant epidemiological studies are scarce, especially for children. OBJECTIVE: To investigate the association of phthalate exposures with body mass index (BMI) and waist circumference (WC) in Chinese school childre…
Three Zn(II) metal-organic frameworks (Zn-MOFs), [Zn2(tib)(HL(1))(H2L(1))0.5]·2H2O (1), [Zn2(tib)(L(2))]·H2O (2) and [Zn3(tib)(L(3))2(H2O)6]·2 H2O (3), have been prepared by reactions of 1,3,5-tris(1-imidazolyl)benzene (tib), and biphenyl-3,3',4,4'-tetracarboxylic acid (H4L(1)), 4,4'-oxydiphthalic acid (H4L(2)), or be…
Won by the hare: A new crystalline microporous solid was prepared that is composed of discrete organic cages made entirely from carbon–carbon bonds. The porosity of this material can be controlled by simple kinetic methods, which afford reproducible access to either a non-porous or porous polymorph.
This article showcases the authors’ predictions for Part B of the second World Wide Failure Exercise. Predictions are made using the failure criteria published in the submission for Part A. In several cases, the original predictions are found to match the experimental data well and no revisions are made. A novel const…
The adsorption properties of framework Sn sites in a siliceous zeolite beta were examined by comparing the adsorption of acetonitrile, diethyl ether, and 2-methyl-2-propanol on a Sn-Beta zeolite, a purely siliceous Beta zeolite, and a siliceous Beta zeolite with impregnated SnO 2, using temperature-programmed desorpti…
We report a plasmonic paper-based analytical platform with functional versatility and subattomolar (<10(-18) M) detection limit using surface-enhanced Raman scattering as a transduction method. The microfluidic paper-based analytical device (μPAD) is made with a lithography-free process by a simple cut and drop method…
Dinickel bisphenoxyiminato complexes based on highly substituted p- and m-terphenyl backbones were synthesized, and the corresponding atropisomers were isolated. In the presence of a phosphine scavenger, Ni(COD)2, the phosphine-ligated syn-dinickel complexes copolymerized α-olefins and ethylene in the presence of amin…
A new force field and a hybrid Monte Carlo/molecular dynamics simulation method are developed to investigate the structural transition of zeolitic imidazolate framework-8 (ZIF-8) induced by N2 sorption. At a high loading (approximately 50 N2 molecules per unit cell), ZIF-8 shifts from low-loading (LL) to high-loading…
Nucleic acid/semiconductor quantum dots (QDs) hybrid systems combine the recognition and catalytic properties of nucleic acids with the unique photophysical features of QDs. These functions of nucleic acid/QDs hybrids are implemented to develop different optical sensing platforms for the detection of DNA, aptamer-subs…
Fiber-reinforced polymer composites are engineered materials commonly used for many structural applications because of the high strength-to-weight and stiffness-to-weight ratios. Although the service life of these materials in various applications is usually between 15 and 20 years, these often keep the physical prope…
New therapies are needed to prevent heart failure after myocardial infarction (MI). As experimental treatment strategies for MI approach translation, safety and efficacy must be established in relevant animal models that mimic the clinical situation. We have developed an injectable hydrogel derived from porcine myocar…
Brought to light: Thin, planar nanojunctions between layered MoS2 and graphitic CN (g-CN) were constructed and allowed fast charge separation across the junction interfaces to facilitate hydrogen photosynthesis. This research represents a proof of concept for the rational fabrication of thin interfacial junctions betw…
We report on the structural and electrical properties of ZnO films grown on surface-treated GaN/Al2O3substrates by chemical bath deposition. X-ray diffraction analysis indicated that the ZnO films had a single-crystalline wurtzite structure withc-axis orientation. The ZnO film exhibited n-type conduction with a carrie…

In this study we report a new method for the synthesis of a silica monolithic column bed with bimodal pores (throughpores and mesopores). The template induced synthesis method was used to direct bimodal pores simultaneously instead of the usual post base-treating method. Block polymer Pluronic F127 was chosen as a dua…
Frequency dependence of the dielectric response is studied for ferroelectric bilayer thin-film capacitors under a cyclic bias voltage. The approach used in this work enables probing strong dielectric nonlinearities at millisecond and microsecond time scales during polarization switching in thin films. The frequency-de…
The relationship between the electrical properties and crystallographic quality (crystallinity) of electroplated copper thin-film interconnections was investigated. The crystallinity of the grains and grain boundaries of the interconnections was evaluated on the basis of the image quality (IQ) value obtained by electr…
The phase behavior of gradient copolymers is studied theoretically using random phase approximation (RPA) and self-consistent field theory (SCFT), focusing on the effects of monomer sequence distribution, or compositional polydispersity, of the polymer chains. The stability of the disordered phase is examined using RP…
