Combining double monochromator, tandem Fabry-Pérot interferometry (TFPI), and photon correlation spectroscopy (PCS), the full range of the dynamic susceptibility of the glass former o-terphenyl is covered (240-440 K). A time resolution of 6 ns is reached by the PCS setup, and the measuring gap between PCS and TFPI has…
The feasibility of the use of piezoelectric drop-on-demand inkjet printing to prepare test materials for trace explosive analysis is demonstrated. RDX (1,3,5-trinitro-1,3,5 triazcyclohexane) was formulated into inkjet printable solutions and jetted onto substrates suitable for calibration of the ion mobility spectrome…
PURPOSE: Acute hypoxia (transient cycles of hypoxia-reoxygenation) is known to occur in solid tumors and may be a poorly appreciated therapeutic problem as it can be associated with resistance to radiation therapy, impaired delivery of chemotherapeutic agents, or metastasis development. The objective of the present st…
This study investigated the in vitro effects of bioactive titanium surfaces on osteoblast differentiation. Three titanium substrates were tested: a commercially pure titanium (Cp Ti), an alkali- and heat-treated titanium (AH Ti), and an apatite-formed titanium (Ap Ti) generated by soaking AH Ti in a simulated body flu…
RuO 2 thin films were grown on thermal SiO 2 (100 nm) and Ta 2 O 5 (4 nm)/SiO 2 (100 nm) substrates at 230 °C by pulsed-chemical vapor deposition using a RuO 4 precursor dissolved in blend of chosen organic solvent (with fluorinated solvents) and 95% N 2 /5% H 2 mixed gas as the Ru precursor and reactant gas, respecti…
The effects of ferromagnetic Co(111) and paramagnetic Cu(111) substrates on the electronic and magnetic structures of Co-phthalocyanine (CoPc) molecule were systemically investigated by means of a plane-wave ultrasoft pseudopotential ab initio electronic-structure calculations within both the local-density approximati…
The choice of analytical method and sample pretreatment has significant consequences for the shape of particle‐size distribution (PSD) frequency curves, and therefore for the evaluation of soil textural parameters. Here, the comparison of several granulometric methods based on different physical principles is presente…
Coated conductors are promising candidates for the construction of high-field magnets. In solenoid magnets built with coated conductors, large screening currents are induced in the superconducting layer by the radial component of the magnetic field. The screening currents generate a screening field that reduces the ce…
A wideband bandpass filter (WBPF) with excellent selectivity is proposed. An equivalent circuit model of the new complementary split-ring resonator (CSRR)-based resonator with good wideband response is presented. A WBPF with strong passband selectivity and wide stopband can be achieved by the new resonators with a pro…
Abstract A general picture of refractive index change mechanisms in glass modified by a femtosecond laser has proven elusive. In this paper, Raman microscopy was used in conjunction with refractive near‐field profilometry to analyse the structure of borosilicate glass (Schott BK7) modified by a femtosecond laser and d…
Marinobacter adhaerens HP15 is the type strain of a newly identified marine species, which is phylogenetically related to M. flavimaris, M. algicola, and M. aquaeolei. It is of special interest for research on marine aggregate formation because it showed specific attachment to diatom cells. In vitro it led to exopolym…
The gas−solid carbonation of nanosized portlandite was experimentally investigated using a static bed reactor under anisobaric conditions. The effects of initial CO 2 pressure (10−40 bar), reaction temperature (30 and 60 °C), and relative humidity were investigated. Three steps of the carbonation process were determin…
In this study, a slurry foaming method was developed to fabricate porous titanium, and two different surface treatments were applied to investigate their effects on the osteoinduction of the implants. Three types of implants, that was porous titanium with no treatment, with chemical-thermal treatment (CTPT), and with…
Abstract We investigate the classical Rayleigh–Taylor instability with a phase‐field method. Despite of the long history of numerical simulations for the Rayleigh–Taylor instability, almost all results were relatively short time experiments. This is partly because of the way of treating the pressure boundary condition…
Reconstituted keratin has shown promise as an orthopaedic biomaterial. This in vivo study investigates the biological response of composite materials prepared from reconstituted keratin containing a high content of hydroxyapatite (HA) (40 wt % HA), implanted for up to 18 weeks in the long bones of sheep. Keratin-HA co…
The implant associated infection is widely considered as a major concern in the field of biomedical applications and this has been the driving force for developing HAp-based biomaterials with antibacterial additives for possible use in prosthetic devices. In our present work, we sintered Hydroxyapatite (HAp) with diff…
This article highlights the emerging use of the interactions of radical π-dimers to drive both molecular recognition and switching processes within supramolecular systems and mechanically interlocked molecular architectures. The enhanced stability experienced by dimers of radical cation species when encapsulated, as c…
BACKGROUND: Intracerebral drug delivery using surgically placed microcatheters is a growing area of interest for potential treatment of a wide variety of neurological diseases, including tumors, neurodegenerative disorders, trauma, epilepsy, and stroke. Current catheter placement techniques are limited to straight tra…
Detection of reactive oxygen species (ROS) released from live macrophage cells (RAW264.7) without any addition of external redox mediators using constant-height and constant-distance mode scanning electrochemical microscopy (SECM) was presented in this Letter. The successful separation of the ROS profile from the topo…
Nanoparticulate systems in various unique configurations are highly effective at detecting protease activity both in vivo and in vitro. In this article, we have summarised the conventional modern methods for monitoring protease activity, and critically appraised recent advances in protease-responsive nanosensors.
