Two new antimony sulfate chlorides named (NH4)2SbCl(SO4)2 and (NH4)SbCl2(SO4) were successfully synthesized through solvent-free synthesis method. exhibits a three-dimensional framework constructed of [SbCl(SO4)2]2– chains NH4+ ions. And the cations play role charge balance provide hydrogen bond with oxygen atoms. shows two-dimensional layer structure that is composed regularly stacked [SbCl2(SO4)]− via hydrogen-bonding interactions. Both titled compounds possess same chemical composition...
. We propose a single-ended readout, multi-resolution detector design that can achieve high spatial, depth-of-interaction (DOI), and time-of-flight (TOF) resolutions, as well sensitivity for human brain-dedicated positron emission tomography (PET) scanners.
As one of the most salt-sensitive crops, strawberry production is severely limited by salt stress. γ--aminobutyric acid (GABA) has been reported to play an important role in immune response plants. In this study, physiological and transcriptomic changes seedlings treated with GABA under stress were investigated explore effect on tolerance. The results showed that exogenous maintained high osmolyte levels, increased antioxidant capacity, decreased ROS levels leaves stress; MDA was reduced...
Bulk single crystals of diguanidinium phosphate monohydrate (G2HP) with dimensions up to 55 × 28 27 mm3 have been grown by solution growth methods. Thermal properties including specific heat, thermal conductivity and expansion were investigated as a function temperature. The heat was measured be 1.339 1.614 J g−1 K−1 over the temperature range 293 347 K. conductivities are descending increases. average linear coefficients along c axes from 298 338 K α11 = 1.878 10−5 α33 1.930 K−1,...
Objective. We propose a novel four-layer depth-of-interaction (DOI) encoding phoswich detector using lutetium-yttrium oxyothosilicate (LYSO) and bismuth germanate (BGO) scintillator crystal arrays for high sensitivity spatial resolution small animal PET imaging.Approach.

A 50 × 10 mm3 monolithic gadolinium aluminum gallium garnet (Gd3Al2Ga3O12; GAGG):Ce crystal coupled to a 8 silicon photomultiplier (SiPM) array was developed; it showed very good system uniformity and high energy resolution of 7.4% at 662 keV. By using convolutional neural network-based positioning algorithm fan-beam calibration method, the detector achieved position ∼1.4 mm depth interaction ∼2 mm. Based on this high-performance detector, we developed coded aperture gamma camera. 1-mCi...
The lattice parameters, five independent elastic constants and the bulk modulus B on applied pressure of hexagonal boron nitride (h-BN) are calculated by using a first-principles pseudopotential method. calculation results in good agreement with experimental theoretical values. It is found that most stable structure h-BN corresponds to axial ratio c/a about 2.652.
Nanostructured Lanthanum hexaboride (LaB6) powders were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution (HRTEM) and photoelectron spectra (XPS). The average size of LaB6 nanoparticles is about 35nm, which are well crystallized with ball or ellipsoid inconspicuous corners covered a 3-5nm thick amorphous layer containing oxygen carbon. absorption in visible near infrared spectrum (NIR) was measured compared micron scale particles. surface...
Abstract Background Monolithic or semi‐monolithic detectors are attractive for positron emission tomography (PET) scanners with depth‐of‐interaction (DOI) capability. However, they often require complicated calibrations to determine the interaction positions of gamma photons. Purpose We introduce a novel hybrid detector design that combines pixelated and elements achieve DOI capability while simplifying positioning. Methods A prototype eight lutetium–yttrium oxyorthosilicate (LYSO) layers...
Abstract Accurate and efficient simulation of gas-liquid two-phase flow is not only pivotal in the broader context energy, chemical engineering, environmental studies but particularly crucial intricate realm nuclear energy. Specifically, energy systems, vapor separation processes within steam generators exhibit highly complex phenomena. The liquid droplets generated these showcase a broad spectrum velocity, droplet diameter, angle parameters. This complexity necessitates meticulous modeling...
