Abstract A series of dicyanomethylene‐substituted 2,5‐di(thiophen‐2‐yl)thieno[3,2‐b]thieno‐quinoids, in which soluble alkyl chains (2‐decyltetradecyls) are substituted at different positions (namely, 2,2′‐positions (Compound 1); 3,3′‐ positions (Compound 2); 6,6′‐positions (Compound 3)), are strategically designed and…
The potential clinical value of developing a novel, nonviral, ultrasound-directed gene and drug delivery system is immense. Investigators soon will initiate clinical trials with the goal of treating a wide variety of maladies using noninvasive, ultrasound-based technology. The ongoing, scientific validation associated…
Abstract A near‐infrared (NIR) light‐triggered nanocarrier is developed for intracellular controlled release with good stability, high nuclease resistance, and good biocompatibility. The nanocarrier consists of a gold nanorod core and mesoporous silica shell, capped with reversible single‐stranded DNA valves, which ar…
Optical antennas represent an enabling technology for enhancing the detection of molecular vibrational signatures at low concentrations and probing the chemical composition of a sample in order to identify target molecules. However, efficiently detecting different vibrational modes to determine the presence (or the ab…
Methods for genetic manipulation of Clostridium ljungdahlii are of interest because of the potential for production of fuels and other biocommodities from carbon dioxide via microbial electrosynthesis or more traditional modes of autotrophy with hydrogen or carbon monoxide as the electron donor. Furthermore, acetogene…

Synthesized organic chemicals, used as inhibitors in mitigating the corrosion of huge quantities of steel articles, pose a major threat to the global environmental problems and health hazards. Naturally occurring products which had been used for natural medication purposes, since the human civilization, are found to i…
AIM: Platelet derivatives serve as an efficient source of natural growth factors. In the current study, α-granules were incorporated into coaxial nanofibers. MATERIALS & METHODS: A nanofiber scaffold containing α-granules was prepared by coaxial electrospinning. The biological potential of the nanofiber scaffold was e…
A superhydrophobic surface on which the contact angle of a water droplet exceeds 170° was reversibly produced by alternate irradiation with UV and visible light. Superhydrophobicity is due to the formation of densely generated submicrometer sized needle-shaped crystals (less than 0.2-0.3 μm diameter and 2.2-2.5 μm lon…
AIM: This work aimed to determine if the treatment outcomes of bladder cancer could be improved by targeting micelles that are decorated with bladder cancer-specific ligands on the surface and loaded with the chemotherapeutic drug paclitaxel. MATERIALS & METHODS: Targeting efficacy and specificity was determined with…
AIMS: To predict the deposition of nanoparticles in a patient-specific arterial tree as a function of the vascular architecture, flow conditions, receptor surface density and nanoparticle properties. MATERIALS & METHODS: The patient-specific vascular geometry is reconstructed from computed tomography angiography image…
We demonstrate generation of linearly polarized pulses from a passively Q-switched Erbium-doped fiber laser. The cavity was designed using only polarization maintaining (PM) fibers and components, resulting in linearly polarized output beam with degree of polarization (DOP) at the level of 97.6%. Reduced graphene oxid…
We report the colloidal synthesis of monodisperse nanocrystals (NCs) of InSb, which is an important member of III-V semiconductor family. Colloidal InSb NC quantum dots showed well-resolved excitonic transitions in the near-infrared spectral range, with the optical band gaps tunable from ∼1.03 eV (1200 nm) to ∼0.71 eV…
AIMS: Melanoma is the most aggressive type of malignant skin cancer derived from uncontrolled proliferation of melanocytes. Melanoma cells possess a high potential to metastasize, and the prognosis for advanced melanoma is rather poor due to its strong resistance to conventional chemotherapeutics. Nanomaterials are at…
Abstract A novel architecture of 3D graphene growth on porous Al 2 O 3 ceramics is proposed for thermal management using ambient pressure chemical vapor deposition. The formation mechanism of graphene is attributed to the carbothermic reduction occurring at the Al 2 O 3 surface to initialize the nucleation and growth…
Here we summarize recent progress in the development of electrolyte-gated transistors (EGTs) for organic and printed electronics. EGTs employ a high capacitance electrolyte as the gate insulator; the high capacitance increases drive current, lowers operating voltages, and enables new transistor architectures. Although…
Biomaterials for tissue engineering scaffolds are subjected to loading at various strain rates at body temperature. Polymeric based biomaterials used for this purpose often have low melting temperature, potentially compromises their mechanical properties during use. In this study, blend of polycaprolactone and 10 wt%…
ErBa2Cu3O7-δ is a type II high temperature superconductor, which is known as the 123-system. This type of superconductor is classified as the most stable high temperature superconductor. This dissertation presents the doping effect of diamagnetic elements (Zn and Pb) and paramagnetic elements (Ca and Nd) in the Er-123…
We study theoretically the inuence of external hydrostatic pressure on the valence band structure in [0001]-oriented AlxGa1-xN/AlN quantum wells used in deep-ultraviolet light emitting devices. The calculations performed using the multi-band kp method with excitonic eects show that for AlxGa1-xN/AlN quantum wells with…
