Abstract One of the first steps in establishing safe handling procedures for explosives is small‐scale safety and thermal (SSST) testing. To better understand the response of homemade or improvised explosives (HMEs) to SSST testing, 16 HME materials were compared to three standard military explosives in a proficiency‐…
The N((2)D) + H2O is a reaction with competitive product channels, passing through several intermediates. Dynamics of this reaction had been investigated by two of the present authors at two collision energies, Ec, using the crossed molecular beams mass spectrometric method ( Faraday Discuss. 2001 , 119 , 27 - 49 ). T…
In this paper, we develop a simple vesicle-assisted chemical reduction approach for synthesizing hollow Ni–Co–B nanospheres. With various characterization techniques, the resulting Ni–Co–B nanospheres are identified as amorphous alloys with a hollow chamber. Coexistence of NiII and CoII species plays a significant rol…
A study was conducted to investigate the microstructure and the mechanical properties of dissimilar resistance spot welds between steel sheets of DP600 and DP1000 using different welding currents for automotive applications. Microstructural characterization, microhardness tests and tensile shear tests of the joints we…
Radiopaque polymer derivatives were successfully prepared through surface diffusion mediated cross-linking of chitosan with iodinated 2,5-dimethoxy-2,5-dihydrofuran. The incorporation of iodine in 2,5-dimethoxy-2,5-dihydrofuran was validated by (1)H NMR and mass spectroscopy. The cross-linking of the glucosamine moiet…
Three heteroleptic divalent-metal alkyl-carbazate-thiocyanate complexes, [M(NCS)2(NH2NHCOOR)2] [M = Co and R = CH2CH3 (1); M = Co and R = CH3 (2); M = Zn and R = CH3 (3)], have been prepared and characterized, and their crystal structures determined. In 1, Co(II) adopts a fairly regular centrosymmetric trans-CoO2N4 oc…
The veneer preprocessing densification is a vital procedure in the manufacturing process of long‐span bamboo‐based engineering material, bamboo‐bundle laminated veneer lumber (BLVL). The adhesive used in the preprocessing densification process was the mixture of phenol formaldehyde (PF) resin and polyvinyl acetate (PV…
We investigate theoretically the structure, crystallinity, and solubility of a high-mobility n-type semiconducting copolymer, P(NDI2OD-T2), and we propose a set of new force field parameters. The force field is reparametrized against density functional theory (DFT) calculations, with the aim to reproduce the correct t…
Bamboo is a natural bio-composite that has outstanding mechanical properties. Fibers are the structural building block of bamboo. Understanding the effect of fiber area on tensile properties of moso bamboo (Phyllostachys pubescens Mazei ex. H. Lebaie) will shed light on natural efficient design of bamboo. In this pape…
We report on the observation of quantized Hall plateaus in a system of two-dimensional Dirac fermions, implemented in a 6.6 nm HgTe quantum well at magnetic fields up to 34 T at nitrogen temperatures. The activation energies determined from the temperature dependence of the longitudinal resistivity are found to be alm…
Through‐thickness polymer pin–reinforced foam core sandwich (FCS) panels are new type of composite sandwich structure as the foam core of this structure was reinforced with cylindrical polymer pins, which also rigidly connect the face sheets. These sandwich panels are made of glass fiber–reinforced polyester face shee…
Conducting porous substrates of high hydrophilicity are advantageous in applications of electrochemical biosensors as host electrodes, offering not only fast charge transport and large sensing surface areas but also necessary wettability in aqueous analytes. In this study, inexpensive, highly hydrophilic (contact angl…
Interlayer exchange coupling in strong/weak/strong ferromagnetic multilayers is investigated as a function of external magnetic field and temperature, with the focus on the magnetization switching near the Curie transition in the spacer composed of a diluted ferromagnet of concentration paramagnetic in the bulk. The e…
A mixed 2D (film) and 3D (nano-column) growth of ruthenium oxide has been experimentally observed for thermally oxidized polycrystalline ruthenium thin films. Furthermore, in situ x-ray reflectivity upon annealing allowed the detection of 2D film growth as two separate layers consisting of low density and high density…
Local compositional changes induced by high repetition rate fs-laser irradiation can be used to produce high performance optical waveguides in phosphate-based glasses. The waveguide refractive index contrast is determined by the local concentration of La, which can be changed by the action of the writing laser pulses.…
We utilize the unique dispersion properties of leaky plasmon polaritons in epsilon-near-zero (ENZ) thin films to demonstrate thermal radiation control. Owing to its highly flat dispersion above the light line, a thermally excited leaky wave at the ENZ frequency out-couples into free space without any scattering struct…
When pipeline repairs are made on high pressure onshore transmission pipelines, in modern times repairs typically involve steel sleeves or composite repair systems. A comprehensive testing program was conducted to evaluate the repair of severe corrosion and dents using composite materials, as well as Type A and B stee…
The strong coupling of inorganic nanocrystals with 2D nanosheets to produce function-enhanced nano-materials with uniform size, dispersion, and high coverage density has long been of interest to scientists from various research fields. Here, a simple and effective method has been described to fabricate ultrafine and w…
Abstract This microreview reveals a new strategy to transcribe supramolecular architectures in self‐organized constitutional hybrids. In particular, the use of communicating reversible‐covalent and supramolecular hydrophobic interfaces between organic/supramolecular and inorganic/siloxane networks represents a useful…
A novel three-photon probe for the imaging of exogenous Zn(II) ions in live cells with varying emission colors under three-photon excitation is developed. The tuning of the charge transfer state and the emission color of the probe was also demonstrated in the presence of acid.
