Abstract “Non-Fickian” diffusion of wood moisture refers to the unexplained anomalous behaviour of water vapour sorption in wood. The depression of moisture diffusion rates in thin sections of wood tissue during moisture content change at high relative humidity is one of the least-understood aspects of “non-Fickian” d…
Since the terrorist attacks on 11 September 2001, structural resistance to explosion has received increasing attention. As bridges are controlling factors in traffic systems, explosion-induced bridge damage will cause great economic loss and social impact, but there is a lack of anti-explosion research for bridges. Th…
A magnetostrictive ferromagnet–polymer composite consisting of steel wires suspended in a polymer matrix has been developed that exhibits large reversible magnetostrictive strain in relatively low magnetic fields. The strain for a fixed field is a nonmonotonic function of wire loading for the longer wires investigated…
We study the near-infrared properties of spherical multishell nanoparticles comprising a loss-less dielectric core enclosed by a concentric layering of metallic–dielectric–metallic nanoshells. The coupling between the metallic shells induces plasmon resonance redshifts and peak splitting in the absorption spectra of t…
Abstract The phase transition between λ-Ti 3 O 5 and β-Ti 3 O 5 is an intriguing process that can be driven in multiple ways. However, the phase transition has not been reasonably and universally analyzed in atomic-scale, because it is limited by experimental inaccessibility. Here, the nudged elastic band method, crys…
Nowadays, with the spread of terrorist attacks in many parts of the world, the design approach to abnormal loadings, such as a blast load, has also become noted of design regulations. In recent years, the dual moment-resisting frame system with steel plate shear wall has been used in the design of structures as a load…
Abstract Laser initiation of energetic materials is a topic of significant interest. An extremely important parameter of initiation for numerous applied tasks is the time delay of initiation from the beginning of laser exposure. Experimental studies of the process of initiation of a number of primary explosives (lead…
Natural attenuation of explosives may occur through microbial mineralization, microbial transformation, and/or immobilization. A demonstration of natural attenuation of explosives was conducted at a former waste lagoon area, at the Louisiana Army Ammunition Plant (LAAP). Objectives of the demonstration were to establi…
To obtain the good flatness of hot-rolled stainless-steel strips, high-precision shape control has always been the focus of research. In hot rolling, the quadratic wave (centre buckle and edge wave) can usually be controlled effectively. However, the quarter buckle of the strip is still a challenge to solve. In this p…
Fusion reactors will require specially engineered structural materials that will simultaneously satisfy the harsh conditions, such as high thermomechanical stresses, high heat loads, and severe radiation damage, without compromising on safety considerations. The simulation of 14.7-MeV protons and 3.6-MeV α-particles i…
We report on the effect of low substrate temperature on the correlation between structure, magnetic properties, and micromagnetic behavior of Fe70Ga30thin films. The enhanced grain size and the decrease in the number of pinning centers are in correlation with the enhanced saturation magnetization and domain size (~0.2…
A ternary solid solution of lead-free Na1/2Bi1/2TiO3-BaTiO3and BiGaO3 (NBT-BT-BG) was prepared using conventional, solid-state synthesis. Compositions were prepared near the morphotropic phase boundary (MPB) of (1- x)NBT-x BT, located near x= 0.04 -0.09, and then systematically substituted with 2-5 mol% BG to investig…
Over 60 billion ceramic capacitors are used worldwide each year. About half are single-layer "disc"-style capacitors. Most of the rest are multilayer devices. Multilayer ceramic capacitors were originally developed in the United States. In recent years, however, the predominant manufacturers, at least of disc capacito…
A novel concept of hybrid treatment for steels is presented. The goal is to produce a hard interstitially hardened/stabilized austenite layer, with an expected improved wear and corrosion resistance, in the surface of high‐hardenability steels. The novelty is in the fact that the thermochemical treatment is performed…
Flexible printed electronic circuits have recently attracted attention as an alternative promising methodology due to the additive process being more environmentally friendly and using less raw material compared to conventional lithography and chemical vapor deposition. However, printed circuits produced by roll-to-ro…
Abstract A film forming method for patterned single-walled carbon nanotube (SWCNT) films was developed by applying photoisomerization of cationic azobenzene as a dispersant. By use of this method, micrometer-sized SWCNT patterned films were directly prepared on various substrates from SWCNT dispersions through short-t…
The molecular engineering of chromophores that enables the controlled and reliable formation of hierarchical solid-state architectures is at the forefront of developing hybrid semiconducting materials. While the rules and principles to assemble monomeric porphyrin-derived building blocks are well established, the aggr…
In this study, we report nitrogen-doped nanodiamond (ND)-integrated crushed graphene (Gr) nanoflakes on nickel hydroxide (Ni(OH) 2, named NH) nanostructures for highly stable nonenzymatic glucose sensors. A chemical vapor deposition route with a simple hydrothermal method was devised in the fabrication of ND-Gr-NH nan…
Nano dolgular polimerlerin ısıl ve mekanik özelliklerini geliştirmek için sıklıkla kullanılan malzemelerdir. Halloysit (HNT) içi boş tüp şeklinde doğal bir alümina silikat nano dolgudur. Bu çalışmada, termoplastik elastomer ailesinin bir üyesi olan kopoliester (COPE) polimerinin ısıl ve mekanik özellikleri organofilik…
Framework Materials Most metal-organic frameworks (MOFs) contain just one type of metal in the nodes connecting the organic linkers. Multivariate MOFs containing multiple metals can offer greater selectivity in sorption and catalytic properties, but determining the arrangement of metals in these materials is challengi…
