Extracorporeal circulation often causes mechanical damage to erythrocytes, which release hemoglobin into the plasma, resulting in postsurgical hazard, so lowering free (f-Hb) level blood is important. In this study, based on good biocompatibility of chitosan/κ-carrageenan and adsorption effect carbon nitride, a chitosan/κ-carrageenan/carbon nitride (CS/κ-Car/C3N4) hydrogel was prepared through charge electrostatic interaction between polysaccharides. The incorporation C3N4 enhanced both...
Laser wakefield acceleration of electrons well beyond 1 GeV and optical guiding ultraintense laser pulses peak powers up to 160 TW over a 4-cm long ablative capillary discharge plasma channel were experimentally demonstrated. Electron beams, with energies 1.8 GeV, generated by using the 130 TW, 55 fs driving pulses. A comparison oxygen-containing acrylic resin (C:O:H = 4:2:7) no polyethylene 1:0:2) measurements suggests that injection electron into is assisted ionization oxygen K-shell electrons.
A palladium/norbornene (NBE)-catalyzed regioselective C-H silylation of free NH-indoles is reported. This protocol uses Pd(OAc)
We demonstrated experimentally the seeding-phase control for a two-stage laser wakefield accelerator with gradient injection. By optimizing seeding phase of electrons into second stage, electron beams beyond 0.5 GeV 3% rms energy spread were produced over short acceleration distance ∼2 mm. Peak beam was further extended 1 by lengthening stage to 5 Time-resolved magnetic field measurements via magneto-optical Faraday polarimetry allowed us monitor processes and in stage.
The reaction and quenching processes of the K(4p<sup>2</sup>P) + H<sub>2</sub> are studied based on new diabatic PESs.
Global diabatic potential energy surfaces (PESs) of the H2S+ system, corresponding to 14A″ and 24A″ electronic states, were built by using neural network method. In ab initio calculations, aug-cc-pVTZ basis set MRCI-F12 method adopted. The topographic features new PESs discussed compared with available theoretical experimental results in detail. spectroscopic parameters obtained from are good agreement previous results. Based on newly constructed PESs, nonadiabatic dynamics calculations S+ +...
ABSTRACT The collision reaction process of Si + ions with HD molecules was studied using the time‐dependent wave packet method within energy range 1.0–3.0 eV. Theoretical research results show that, except in lower range, throughout whole studied, competitive ability D SiH product channel is stronger than that H SiD channel. comparison integral cross sections experimental indicates for and channels are general good agreement values. differential demonstrated angular distributions products...
A palladium(II)-catalyzed norbornene derivatives-mediated selective ortho -C−H silylation of free NH-carbazoles has been developed for the synthesis arylsilanes. Such a conversion provides access to range arylsilanes with exclusive...
To investigate the risk factors for relapse among elderly schizophrenia patients undergoing maintenance phase treatment, aiming to offer insights prevention in this population. A survey was conducted of who attended outpatient clinics at a specialized psychiatric hospital from October, 2021 September, 2023. The included both general and clinical data. Univariate analysis multivariate non-conditional logistic regression were identify independent schizophrenic treatment. receiver operating...
An efficient palladium-catalyzed strategy for the synthesis of indolo[1,2- f ]phenanthridine derivatives has been developed. In presence Pd(OAc) 2 , N -(2-halophenyl)-indoles and iodobenzenes proceeded smoothly to obtain corresponding ]phenanthridines in moderate...
A new global potential energy surface (PES) of the O+ + H2 system was constructed with permutation invariant polynomial neural network method, using about 63 000 ab initio points, which were calculated by employing multi-reference configuration interaction method aug-cc-pVTZ and aug-cc-pVQZ basis sets. For improving accuracy PES, set extrapolated to complete limit two-point extrapolation method. The root mean square error fitting only 5.28 × 10-3 eV. spectroscopic constants diatomic...
By controlling electron injection into the second period of laser-driven wakefield in a downward density ramp, high-quality low-energy beam can be accelerated short segment high-density plasma. After ramp followed by low-density plasma plateau, pre-accelerated seeded first for cascaded acceleration at an optimized phase. A monoenergetic with peak energy ∼1.2 GeV generated from length 12 mm and 9 × 1017 cm−3, driven laser pulse power 77 TW. modifying stage comprising several density-ascending...
An electron beam with the maximum energy extending up to 1.8 GeV, much higher than dephasing limit, is experimentally obtained in laser wakefield acceleration plasma density of 3.5 × 1018 cm−3. With particle cell simulations and theoretical analysis, we find that intensity evolution plays a major role enhancement gain. While bubble length decreases due intensity-decay pulse, phase can be locked, which contributes overcoming dephasing. Moreover, described for phase-lock electrons uniform...
Abstract UV radiometers are widely employed for irradiance measurements, but their periodical calibrations not only induce an extra cost also time‐consuming. In this study, the KI/KIO 3 actinometer was applied to calibrate radiometer detectors at 254 nm with a quasi ‐collimated beam apparatus equipped low‐pressure lamp, and feasible calibration conditions were identified. Results indicate that washer constraining light indispensable, while size (10 or 50 mL ) of beaker containing solution...
