For improved physical stability and fast accumulation in sentinel lymph nodes in vivo, indocyanine green (ICG) was incorporated into exosomes (EXOs) to form a novel ICG-based near-infrared fluorescence probe. Compared with free ICG, prepared ICG-TBAI-encapsulated EXOs (ICG/EXOs) smaller than 50 nm had greater physicoc…
Abstract A plastic‐bonded explosive (PBX) in the form of a sheet was formulated comprising of 1,3,5‐trinitroperhydro‐1,3,5‐triazine (RDX) and an hybrid binder system containing a linear thermoplastic polyurethane and a fluoroelastomer (Viton). The effect of a fluoroelastomer on the explosive as well as mechanical prop…
Dopant-profile independent electron transport has been observed through a combined study of temperature dependent electrical resistivity and magnetoresistance measurements on a series of Ti incorporated ZnO thin films with varying degree of static-disorder. These films were grown by atomic layer deposition through in-…
Today, there is an intense search for new electron donor polymers for the active layers of organic solar cells. The synthesis of copolymers, in which there is a mix of electron donor monomers with others that are electron acceptors, is a currently employed approach that is used to obtain new polymers with more interes…
We report on the excitation of acousto-eletric (AE) charge transport in monolayer graphene by acoustic transducers based on aluminum nitride thin films. The acoustic waves induced macroscopic current flow that linearly scaled with input power. The AE current exhibited unique frequency dependence due to special configu…
The interaction of defect‐rich nanocrystalline indium oxide films, which have previously shown to exhibit excellent ozone sensing properties, with O3, O2, and H2O molecules is investigated using ultra‐violet and X‐ray photoelectron spectroscopy. The investigated samples are grown by metalorganic chemical vapor deposit…
Purpose – The purpose of this paper is to focus on tracheal stent production with the aim of investigating the available devices and improving their performances. The biomedical field is a continuously growing area of the market always in search of the most innovative and competitive solutions for healthcare. Beside t…
RATIONALE: Fast methods that allow the in situ analysis of explosives from a variety of surfaces are needed in crime scene investigations and home-land security. Here, the feasibility of the ambient mass spectrometry technique desorption atmospheric pressure photoionization (DAPPI) in the analysis of the most common n…
OBJECTIVE: The aims of the present work were to study a new porous Nurse's A ceramic (Si-Ca-P-based material) bone substitute and examine its mechanical properties in vitro and the biocompatibility, osteoconductivity and resorption process in vivo. MATERIALS AND METHOD: Porous ceramic scaffolds were prepared by solid-…
Beeswax, a natural nontoxic biological material, is used as the gate dielectric of flexible low-voltage indium–zinc-oxide (IZO)-based homojunction thin-film transistors (TFTs) on paper substrates. A high specific capacitance of 5$\mu \text{F}$/cm2is measured at 1 Hz in the beeswax film due to the electric-double-layer…
Stress-relieved pure tungsten received three damage levels (0.10, 0.25 and 0.50 dpa) by self-tungsten ion beam irradiation at room temperature. Positron annihilation spectroscopy showed the formation of mono-vacancies and vacancy clusters after ion beam exposure. In the first irradiation step (0–0.10 dpa) some splitti…
An optical functional film applicable to various lighting devices is demonstrated in this study. The phase separation of two immiscible polymers in a common solvent was used to fabricate the film. In this paper, a self-organized lens-like structure is realized in this manner with optical OLED functional film. For an O…
Presented is a comparison between full-scale façade tests where SP Fire 105 and BS 8414-1 were used regarding repeatability and the use of modelling to discern changes in the set-ups. Results show that the air movements around the test set-up (the wind) may have a significant impact on the tests and that the heat expo…
ZnO films with a c-axis significantly inclined away from the surface normal were grown by a remote plasma sputtering technique at room temperature. The films were used to make solidly mounted resonators (SMRs) operating in shear mode at a resonant frequency of 1.35 GHz. Control of the ZnO microstructure was achieved u…
ABSTRACT The high‐ortho phenolic epoxy fibers (HPEFs) were prepared by the crosslinking of heat‐meltable spun filaments derived from melt‐spinning of the novolac epoxy resins copolymerized among phenol, formaldehyde, and epichlorohydrin (ECH) in the presence of zinc acetate and sulfuric acid catalyst, and cured in a c…
This paper presents design and implementation of a color wavefront holographic printer. The printer output is a white light viewable volume hologram composed as a two-dimensional (2-D) array of elemental holograms. The three-dimensional (3-D) input data for the printer are encoded as computer generated holograms (CGHs…
The efficiency of a linear oscillating actuator (LOA) can be increased by reducing the mechanical losses caused by the crankshaft mechanism. In addition, this system has lower noise and fewer vibration effects than rotary motors. In this paper, the features of the stator core in an LOA are examined with regard to a ne…
Co-crystals between drug molecules and coformers have shown great potential to optimize the stability and dissolution profiles of drugs. However, most of the coformers studied so far are small molecules. Here, we use diflunisal (DIF) as the model drug, and show that it could form co-crystals with multiple types of lin…
The cavitation erosion resistance of an X5CrNi18-10 stainless steel, solution treated at temperatures in the range of 1000–1100 °C for 5–50 mins, was investigated using a piezoceramic vibrating system. The variation of the technological parameters led to changes in the degree of the chemical homogeneity and the grain…
A moisture‐dependent and temperature‐dependent constitutive model for paper materials was proposed and implemented into a finite element model of the paper hydroforming process. Experimental hydroforming was conducted at temperatures of 23°C and 110 °C and moisture contents of 6.9 and 10.6 (respectively corresponding…
