Co(OH)₂ arrays/GNSs composites, which are constructed by preferentially oriented growth, exhibit a high-performance when used as anode materials for lithium-ion batteries.

Abstract Any product must undergo precise manufacturing before use. The damage incurred during the process can significantly impact residual strength of post-manufacturing. However, relationship between bending and manufacturing-induced remains unclear, despite being a crucial parameter for assessing material service life performance, leading to decrease in performance reliability. This study focuses on investigating crack generation through theoretical experimental analyses scratching,...

To explore the impact of non-uniform initial bubble sizes on hydrodynamics behavior separation zone in a dissolved air flotation (DAF) tank, three-dimensional (3D) model DAF tank was established. Subsequently, computational fluid dynamics (CFD) simulations corresponding were conducted based realizable k-ε turbulence model, Eulerian-Eulerian multiphase flow and population balance (PBM). The reliability prediction results 3D evaluated by comparing gas holdup velocity vector data obtained from...

AIM: To analyze the clinical and pathological features of 89 patients presenting as lacrimal gland prolapse (LGP). METHODS: This retrospective study included LGP. Magnetic resonance imaging (MRI) scan was performed for all patients. Pathology immunohistochemical staining prolapsed tissue were during surgery. The histopathological subtype obtained, related manifestations different marked. RESULTS: Among involved, includes dacryoadenitis (43%; n=38), focal lymphocytes infiltration (20%; n=18),...

The intelligent development in building design, construction, and operation & maintenance is exceptionally rapid, which has become a trend that cannot be ignored the current field of architecture. With help prompt engineering, architects can use generative AI to lay out space designs even generate 3D drawings. Artificial intelligence agents act as designers owners, representing all parties involved life cycle. In this way, they simulate cycle, providing comprehensive perspective...

Abstract In order to understand the effect of polymorphic transformation on impact sensitivity heated hexanitrohexaazaisowurtzitane (CL‐20) and its composite, transition CL‐20 crystal under heat stimulation was investigated using powder X‐ray diffraction (PXRD) microscopic methods. The effects particle size PDA coating were explored. experiments showed that at 160 °C related surroundings crystals. As temperature increases, changes in molecule conformation larger crystals more facilitated...

In order to study the fracture behavior and structure evolution of 1,3,5-Triamino-2,4,6-Trinitrobenzene (TATB)-based polymer bonded explosive in thermal-mechanical loading, in-situ studies were performed on X-ray computed tomography system using quasi-static Brazilian test. The experiment temperature was set from −20 °C 70 °C. Three-dimensional morphology cracks at different temperatures obtained through digital image process. various modes compared by scanning electron...

Abstract Gas–liquid flow in the dissolved air flotation (DAF) tank was studied through computational fluid dynamics realizable k-ε model and population balance (PBM) to predict gas content of different mediums (air, carbon dioxide, chlorine) at heights separation zone DAF tank. Simultaneously, a particular focus placed on studying effects bubble aggregation breakage content. The results indicated that there were virtually no bubbles present region below 0.1 m zone. could meet needs for when...

This paper investigates the wave propagation in small and micro-cell of urban environments. The goal was to identify main contribution as a function base station (BS) antenna height, distance from environment. Three typical cases were studied where BS is: (1) above rooftop, (2) at rooftop height (3) much below surrounding buildings (microcell case). A 2D ray tracing horizontal plane vertical have been combined perform coverage predictions three cases. prediction results are compared...

In order to inspect welding defects of the laser stainless steel, piezoelectric bimorph focusing method is presented, non-destructive testing system setup. The cutting part weld sample used measure width by metallography and system. results show that unevenly distributed, relation between ultrasonic signal amplitude showed a good linearity, which means can be width.

This paper investigates the effects of building heights on results our MCOR prediction tool in area Munich (Germany). The goal is to compare predictions performed assuming buildings having a constant height and either (1) considering with their real or (2) measurements. three dimensional layout (contour height) topographical data are geometrical inputs tool. study shows that can be well approximated by made height. errors between two Gaussian standard deviation about 4 dB. A reasonable...

Octagon (HMX) based metalized explosive containing boron (B)/aluminum(Al) compound powder, oxidizer ammonium perchlorate(AP) and binder hydroxyl-terminated polybutadiene(HTPB) was designed prepared. The appearance morphology of B Al powder B-Al were observed by SEM. effects HMX AP on the thermal oxidation characteristics investigated TG-DSC. A deeper understanding reaction kinetic mechanism made. sensitivities(impact sensitivity, friction electrostatic spark cap initiation sensitivity)...

This paper presents a preliminary comparison of two coverage prediction methods developed for urban microcellular environments. In this study particular building layout is chosen as an example. The considered are (1) ray tracing method taking into account multiple specular reflections and single diffraction phenomena (2) time domain approach based on transmission line matrix (TLM) method. Both consider infinitely high buildings no ground reflection. results both compared to measurements...

A scheme that combines 256/128/64 quadrantal amplitude modulation (QAM) adaptive with constant zero autocorrelation sequence (CAZAC) precoding in a multi-band orthogonal frequency division multiplexing (MB-OFDM) ultra-wideband over fiber (UWBoF) system is proposed this paper. CAZAC enables relatively balanced signal-to-noise ratio (SNR) within each band, and the use of optimizes upper limit transmission performance subband.
