Summary This work investigates the influence of the out‐of‐plane orientation of carbon fibers on the reaction‐to‐fire characteristics of polymer matrix composites. A deep insight into combustion processes is gained, which is necessary to fully understand and assess advantages of composites with out‐of‐plane fiber angl…
The photolabile analogue of the broad-spectrum opioid antagonist naloxone, 3- O -(4,5-dimethoxy-2-nitrophenyl)carboxymethyl naloxone (also referred to as “caged naloxone”, 3- O -(α-carboxy-6-nitroveratryl)naloxone, CNV-NLX), has been found to be a valuable biochemical probe. While the synthesis of CNV-NLX is simple, i…
Surface chemistry is believed to be the key parameter affecting the aggregation and breakage of colloidal suspensions when subjected to shear. To date, only a few works dealt with the understanding of the role of the physical and chemical properties of the particles' surface upon aggregation under shear. Previous stud…
PURPOSE: To detect neuronal activity-evoked pH changes by amide proton transfer-chemical exchange saturation transfer (APT-CEST) MRI at 7 T. METHODS: Three healthy subjects participated in the study. A low-power 3-dimensional APT-CEST sequence was optimized through the Bloch-McConnell equations. pH sensitivity of the…
Sufficient rubber stopper sealing performance throughout the entire sealed product life cycle is essential for maintaining container closure integrity in the parenteral packaging industry. However, prior publications have lacked systematic considerations for the time-dependent influence on sealing performance that res…
Biological systems often generate unique and useful structures, which can have industrial relevance either as direct components or as an inspiration for biomimetic materials. For fabrication of nanoscale silica structures, we explored the use of the silaffin R5 peptide from Cylindrotheca fusiformis expressed on the su…
For Herschel SiC primary mirror purpose, a new approach of comparative CTE measurement has been developed; it is based on the well known bimetallic effect (“biceramic” in this case) and also optical measurements. This method offers a good CTE comparison capability in the range of 170-420K (extensible to 5-420K) depend…
Even though the term co-crystal remains topic of debate, general consensus evolves towards defining co-crystals as crystalline compounds constructed of 2 or more neutral components which are, in their pure form, solid at room temperature and under atmospheric pressure. In most cases this definition clearly distinguish…
In order to utilize the high repetition rates now available at X-ray free-electron laser sources for serial crystallography, methods must be developed to softly deliver large numbers of individual microcrystals at high repetition rates and high speeds. Picosecond infrared laser (PIRL) pulses, operating under desorptio…
Abstract Ferroelectric crystallites embedded into a dielectric matrix experience temperature-dependent elastic strains caused by differences in the thermal expansion of the crystallites and the matrix. Owing to the electrostriction, these lattice strains may affect polarization states of ferroelectric inclusions signi…
β-NaGdF <sub>4</sub> :Eu <sup>3+</sup> ,Er <sup>3+</sup> nanoparticles were synthesized at room temperature. The synthesis is robust, easily scalable, and convenient. It is suitable for the whole lanthanide series.
Abstract Lithium-beryllium metal hydrides, which are structurally related to their parent compound, BeH 2 , offer the highest hydrogen storage capacity by weight among the metal hydrides (15.93 wt. % of hydrogen for LiBeH 3 ). Challenging synthesis protocols have precluded conclusive determination of their crystallogr…
An approach to understand the effect of intermolecular actions on the nematic stability, a series of tolane compounds nH containing intermolecular π–π stacking, dipole–dipole and hydrogen bond interactions, are developed and investigated. Their mesophase behaviour were measured by differential scanning calorimetry (DS…
ABSTRACT Functional chemical modifications on poly(ethylene terephthalate) (PET) fibers via radical graft polymerization could be controlled by managing mutual interactions and affinities between different components in the grafting reaction system. Hansen solubility parameters was used as a tool to quantify affinitie…
We have developed and implemented a new ab initio code, C eres (Computational Emulator of Rare Earth Systems), completely written in C++11, which is dedicated to the efficient calculation of the electronic structure and magnetic properties of the crystal field states arising from the splitting of the ground state spin…
The structural, electronic, and magnetic properties of phosphorene doped with transition‐metal (TM) atoms have been investigated within the framework of density functional theory based on spin‐polarized first‐principles calculations. Strong orbital hybridization is exhibited between TM atoms and P atoms, where covalen…
Abstract Herein, a tunable metamaterial absorber was realized by using two-dimensional (2D) plasma photonic crystals (PPCs). A photonic band gap (PBG) can be obtained in the proposed 2D PPCs, which runs at frequencies from 1.7 to 1.93 GHz. The fabricated absorber is tunable and is composed of excited plasma tubes with…
Samples of electrolytic tough pitch copper were deformed in equal channel angular pressing with enhanced productivity to quickly refine its initial coarse-grained microstructure at room temperature. The evolution in microstructure and changes in a broad range of properties were compared to a sample in the undeformed s…
Composites based on ethylene propylene diene rubber (EPDM) loaded with different contents of flax fibers were irradiated using accelerated electron beams at various irradiation doses (75, 150, 300, and 600 kGy). The mechanical, physical, thermal properties, and morphology were analyzed as a function of e‐beam irradiat…
To exploit the extraordinary property of graphene in practical electrical and optical devices, it is necessary to produce large-sized, single-crystal graphene. Atmospheric pressure chemical vapor deposition (APCVD) on polycrystalline Cu surface is a promising scalable route of graphene synthesis but the unavoidable mu…
