A magnetohydrodynamic loading technique was used to shocklessly compress beryllium to peak longitudinal stresses of 19–110 GPa and, subsequently, unload in order to determine both the compressive response and also the shear stress supported upon release. Loading strain rates were on the order of 106 s−1, while the unl…
A strong denaturant, guanidinium hydrochloride (GdnHCl), is shown to delay and alter the inherent aggregation pathway of bovine serum albumin (BSA) from a downhill polymerization to a nucleated polymerization. We hypothesize that such an alteration is closely connected to the conformational population of the protein,…
Herein, we describe the surface modification of an S-nitrosated polymer derivative via H2O plasma treatment, resulting in polymer coatings that maintained their nitric oxide (NO) releasing capabilities, but exhibited dramatic changes in surface wettability. The poly(lactic-co-glycolic acid)-based hydrophobic polymer w…
Abstract Simultaneous targeted cancer imaging, therapy and real‐time therapeutic monitoring can prevent over‐ or undertreatment. This work describes the design of a multifunctional nanomicelle for recognition and precise near‐infrared (NIR) cancer therapy. The nanomicelle encapsulates a new pH‐activatable fluorescent…
Abstract A new mechanism for enhanced phosphorescence emission in the solid state (EPESS) in cyclometallated Ir complexes with the general formula [Ir(CN)2(NO)] involving distortion of the six‐membered chelate ring of the ancillary ligand is proposed. Photophysical and computational studies show that neither π‐stackin…
Abstract Micronanofabrication technologies developed so far pursue faithful conversion from digital models to matter structures. This is vital for microdevices in optics, mechanics, and electronics, where device shape and size matter. However, biotissues grow under rich environmental factor interactions, as demands no…
Abstract Two iridium(III) diimine complexes [mono(1,10‐phenanthroline)bis(triphenylphosphine)(dihydrido)iridium(III) hexafluorophosphate (1) and mono(1,10‐phenanthroline)bis(triphenylphosphine)(hydrido)(chloro)iridium(III) hexafluorophosphate (2)] have been synthesized from a single two‐step reaction. The structures o…
Nylon 6 electrospun nanofibers mat was prepared via electrospinning for the removal of three estrogens, namely, diethylstilbestrol (DES), dienestrol (DS), and hexestrol (HEX) from aqueous solution. Static adsorption as well as the dynamic adsorption was evaluated by means of batch and dynamic disk flow mode, respectiv…
Spin-dependent transport properties of nanodevices constructed by iron-phthalocyanine (FePc) molecule sandwiched between two zigzag graphene nanoribbon electrodes are studied using first-principles quantum transport calculations. The effects of the symmetry and spin configuration of electrodes have been taken into acc…
BACKGROUND: Plant cell walls are complex structures that full-fill many diverse functions during plant growth and development. It is therefore not surprising that thousands of gene products are involved in cell wall synthesis and maintenance. However, functional association for the majority of these gene products rema…
ZrP with large surface, mesoporous volume, and size was prepared. Its catalytic performance was evaluated in hydrolytic hydrogenation of cellulose to sorbitol/mannitol combined with commercial Ru/C. A significantly enhanced sorbitol/mannitol yield was obtained as compared with that of the water-soluble acidic phosphat…
ABSTRACT In this article a nanocomposite based on starch gel, a renewable polymer, and montmorillonite clay (MMT) is proposed as a host system for the slow‐delivery of a hydrophobic herbicide loaded in very high contents (50% in total weight), where the nanocomposite structure controls the release by imposing diffusio…
An ultramicroporous metal–organic framework (MOF) is reported that contains 0.35 nm nanotube-like channels with an unprecedented concentration of vacant Cu II coordination sites. The nonintersecting, narrow channels in [Cu 3 (cdm) 4 ] (cdm = C(CN) 2 (CONH 2 ) − ) align in two perpendicular directions, structurally res…
Nanorattles, as promising functional hollow nanomaterials, show considerable advantages in a variety of applications for drug delivery, biosensors, and biomedical imaging because of their tailored ability in both the movable core and shell. In this study, we formulate a facile controllable route to synthesize a monodi…
We controlled the fluorescence emission of a fluorescently labeled iron oxide nanoparticle using three different nanomaterials with ultraefficient quenching capabilities. The control over the fluorescence emission was investigated via spacing introduced by the surface-functionalized single-stranded DNA molecules. DNA…
The demand for safe and clean energy sources has become more important than ever worldwide. Thermionic power generation is one of these energy sources, which directly converts heat into electrical energy using thermionic electrons. We developed a micro-gap thermionic power generator, which operates at relatively low t…
Understanding the ultrafast dynamics of excited state evolution and carrier generation at the complicated titania/dye/electrolyte interface is crucial for the development of narrow energy-gap organic dyes to enhance the performance of dye-sensitized solar cells (DSCs). We herein modulate the energy-levels of N -annula…
Abstract Conductive polymer composites of segmented polycarbonatediol polyurethane and expanded graphite (EG) have been synthesized with different amounts of EG conductive filler (from 0 to 50 wt%). SEM, X‐ray diffraction measurements, Fourier transform infrared and Raman spectroscopies demonstrated a homogeneous disp…
An excellent chiral symmetry-breaking spontaneous enantiomeric resolution phenomenon, denoted preferential enrichment, was observed on recrystallization of the 1:1 cocrystal of dl-arginine and fumaric acid, which is classified as a racemic compound crystal with a high eutectic ee value (>95 %), under non-equilibrium c…
Abstract A set of surfaces with different Cassie fractions were fabricated. For a given Cassie fraction surfaces had different pillar diameter and spacing combinations. Advancing and receding contact angles of both water and ethylene glycol were measured on the fabricated surfaces. We examined the effects of both surf…
