Although calcium carbide slag is a kind of solid waste, but it promising raw material for preparing direct solar energy storage materials. In this study, we investigated the...
Carbide slag is a solid waste with high content of reactive CaO, which can be used as an active material for the chemical absorption CO2 and calcium looping. Calcium looping CaO-based absorbents one most promising methods thermochemical energy storage. However, sintering pores reduction in diffusion rates carbonization/calcination cyclic reaction progresses have posed challenges to practical application absorbents. This study proposes method alleviating pore structure by improving activity...
Purpose This study aimed to analyze the severity of condition and prognosis patients with anti-gamma-aminobutyric-acid type B receptor (anti-GABA R) encephalitis tumors. Methods Patients anti-GABA R admitted one two hospitals from 2020 2022 were enrolled divided into tumor non-tumor groups. The clinical characteristics, severity, treatment options, groups compared analyzed. Results Eighteen included, ten whom had comparison characteristics showed that rates status epilepticus coma...
To research the efficient and economical desulfurization of Lingshi high sulfur coal (LS), influence acid alkaline additives on an ultraviolet (UV) light oxidation system was assessed. Sodium hydroxide (NaOH) oxalic (OA) were selected as additives, respectively, to investigate whether could promote oxidative in UV–H2O2 system. The samples investigated via scanning electron microscopy (SEM), Brannuer–Emmett–Teller analysis (BET), contact angle (CA), Fourier transform infrared spectroscopy...
Cesium doped WO3 (Cs-WO3) photocatalyst with high and stable oxidation activity was successfully synthesized by a one-step hydrothermal method using Cs2CO3 as the metal ion source tungstic acid (H2WO4) tungsten source. A series of analytical characterization tools oxygen precipitation tests were used to compare effects different additions on crystal structure microscopic morphologies. The UV–visible diffuse reflectance spectra (DRS) Cs-doped material exhibited significant red shift in...
Herein, calcium-based energy-storage materials that directly absorb solar energy were prepared through wet modification of carbide slag (solid waste). It was found at a carbonization temperature 700°C and...
BACKGROUND: Effective analgesia is required to ensure maternal and neonatal safety. OBJECTIVE: To compare the therapeutic effects of applied throughout labor during first stage in women with pregnancy-induced hypertension (PIH). METHODS: In this study, 120 puerperae PIH who gave birth our hospital were enrolled as study participants randomized into two groups (n= 60 each group) using a coin flip. Those received observation group, those administered control group. The analgesic effects,...
Carbide slag is a solid waste with high calcium content that generated from acetylene production. To achieve efficient resource utilization of carbide slag, this work mainly adopts dual modification method combines the doping inert substances wet mixing acetic acid to convert into highly active CaO-based energy storage materials. Because addition and dopants, performance composite material significantly enhanced. After 20 cycles, carbonization conversion rate density dual-modified (AC-CMZ75)...
A highly efficient visible-light-driven photoanode, N2-intercalated tungsten trioxide (WO3) nanorod, has been controllably synthesized by using the dual role of hydrazine (N2H4), which functioned simultaneously as a structure directing agent and nitrogen source for N2 intercalation. The SEM results indicated that controllable formation WO3 nanorod changing amount N2H4. β values lattice parameters monoclinic phase volume changed significantly with nW: nN2H4 ratio. This is consistent addition...
Abstract BACKGROUND Microwave‐assisted and Fenton reagents were combined to enhance the removal effect of sulfur from coal. The coal samples before after desulfurization characterized by various testing methods such as X‐ray photoelectron spectroscopy, diffraction scanning electron microscopy.
