To design and synthesize well-tailored nanocomposites that can be utilized in a range of applications, including self-healing, we must establish a better fundamental understanding of the coupling between radical polymerization reactions and the dynamics of the host solution, which often contains a variety of nanoinclu…
The irradiation effects of LD laser on thin aluminum alloy plates are studied in experiments characterized by relatively large laser spot and the presence of 0.3Ma surface airflow. A high speed profilometer is used to record the profile change along a vertical line in the rear surface of the target, and the history of…
Time-of-flight magnetic resonance angiography is used for craniocervical arterial evaluation. Absent flow-related signal may be the result of slow flow, complex flow, or focal susceptibility effects. We report a case with complete absence of flow-related signal in the intracranial and cervical vessels due to ferumoxyt…
Conductive properties of crystalline organic semiconductors depend to a great extent on the presence of traps. One of the possible sources of traps are impurity molecules incorporated into the crystal lattice. The equilibrium crystal structure around an impurity in anthracene and the corresponding depth of shallow tra…

Ionic Liquids Heavy pnictogen tricyanides form amorphous polymers in the solid state. In their Communication on page 16012 ff., A. Schulz et al. show that this polymer formation can be avoided by using ionic liquids (e.g., [BMIm][OTf]) as reaction media due to formation of [E(CN)3X]− ions (E=Sb, Bi; X=OTf−), which pre…
Although much progress has been made in the treatment of diseases such as, for example, cancer, in this last decade, new approaches are necessary for improving existing therapies or developing new techniques of treatment in order to minimize deleterious side effects and to increase patient survival
One of the most successful theoretical frameworks for inhomogeneous polymeric systems, such as block copolymers, is the self-consistent field theory (SCFT). This chapter reviews various approaches to solving the SCFT equations, emphasizing applications to the study of the self-assembly of multiblock copolymers. It tal…
Hi Reddit! My name is Shannon Bragg-Sitton and I’m here today with a few other researchers from Idaho National Laboratory. This is Nuclear Science Week, so we thought it would be great to start a conversation about low-carbon energy systems – specifically nuclear and renewables. Commercial nuclear power currently prov…
In this paper, improving mechanical properties of duplex stainless steel by spinodal reaction inhibitors has been discussed. Spinodal gaps can be minimized when the host particles are minimized to the nanoscale. The Cahn-Hilliard Equation and the Allen-Cahn Equation on Manifolds with Conical Singularities can be relat…
Depending on the phase behaviour, liquid crystals (LC) can be classified into thermotropic and lyotropic liquid crystals. This chapter provides an overview of the various methods used in simulating self-assembly phenomena in liquid crystals. It describes prominent atomistic molecular dynamics (MD) studies of the LC ph…
Self-assembly, a governing principle by which materials form, is the autonomous organization of matter into ordered arrangements. It is typically associated with thermodynamic equilibrium, the organized structures being characterized by a minimum in the system's free energy, although this definition is too broad. This…
maximum loss, which does not depend much on the shape of the wire.
Series sulfur and nitrogen organic compounds were prepared in our previously paper(1), which act various compounds ( thia, sulfur, aze, sulfide ) from halogenation reaction ,condensation reaction, cyclization reaction . The synthesized compounds have been studied ((chromatography behavior , DSC- thermal measurements))…
The purpose of this thesis is to develop, establish and apply novel quality assurance (QA) methods for nuclear and high-energy physics particle detectors. The detectors should be maintenance-free since devices can only be replaced during long technical shut-downs. Furthermore, the detector modules must endure handling…
Nanoparticles as drug delivery systems enable unique approaches for cancer treatment. Cancer is a leading cause of deaths. Millions of people are diagnosed with cancer every year. Owing to the development of nanotechnology and biotechnology, nanoparticles of biodegradable polymers as effective drug delivery systems ha…
Petroleum, heavy oil, and tar sand bitumen are not usually found where the precursors were laid down, but in reservoirs where accumulation occurs after it has migrated from the source rocks through geologic strata. In addition, the theory that the petroleum precursors form a mix that is often referred to as “protopetr…
Abstract. Fracture mechanics testing at dynamic loading conditions requires appropriate methods for the measurement of force and displacement. In some cases additional measurement techniques must be used to obtain further information like the time of crack initiation. Dedicated standard pro-cedures for impact type dyn…
Abstract. Materials characterized by a regular structure and possessing quasi-brittle or quasi-ductile fracture type are investigated, the specific linear size of a structured element being known. When both necessary and sufficient criteria are derived, the Neuber-Novozhilov approach is used. The modified Leonov-Panas…
A damage model applicable to ceramics subjected to dynamic compressive loading has been developed.The model was based on damage micromechanics and wing crack nucleation and growth.Tension wing cracks nucleated and propagated from the tip of the sliding cracks in the direction of maximum applied compression when the st…
