In this paper, a single template method was used to investigate the synthesis of hierarchical ZSM-5 zeolite by investigating the crystallization time and temperature. On this basis, this paper studied the catalytic performance of the molecule to methanol, and then calculated the ZSM-5 using the methanol conversion rate and liquid hydrocarbon mass formula. Finally, it is found that the reason for the deactivation of the catalyst is that when the temperature of the reaction tube is below 370?, the oil phase is yellow or it is not produced, and the water quality is obviously not good enough. Therefore, it is necessary to strengthen the catalyst of multiple catalytic factors, so as to promote the catalytic methanol production of gasoline technology and made it more perfect.

OBJECTIVE: Sepsis and septic shock are the major causes of death in intensive care units (ICUs) worldwide. A large amount of studies on their pathophysiology have revealed an imbalance in the inflammatory network leading to tissue damage, organ failure, and ultimately, death. Cytokines, proteases, lipid mediators, vasoactive peptides, and cell stress markers play key roles in pathophysiology of sepsis. Although anti-inflammatory mediators can neutralize the promoting role of pro-inflammatory mediators, but persistent immune regulation may cause host susceptibility to concurrent infections. Therefore, it is a great challenge to seek effective clinical therapy against sepsis. To understand the complicated interplay between pro- and anti-inflammatory agents in sepsis, and their interaction in signal transduction and immune regulation in sepsis constitute vital significance to the prevention and control of sepsis. Summarize the latest findings about mediators associated with sepsis and innate and adaptive immune system at home and abroad in recent years, and illustrate the impact of its effects on sepsis, which may lead to resolution of many unexplored queries in the future.

Lead zirconate (PbZrO3 or PZ)-based antiferroelectric (AFE) materials, as a group of important electronic materials, have attracted increasing attention for their potential applications in high energy storage capacitors, micro-actuators, pyroelectric security sensors, cooling devices, and pulsed power generators and so on, because of their novel external electric field-induced phase switching behavior between AFE state and ferroelectric (FE) state. The performances of AFE materials are strongly dependent on the phase transformation process, which are mainly determined by the constitutions and the external field. For AFE thin/thick films, the electrical properties are also strongly dependent on their thickness, crystal orientation and the characteristics of electrode materials. Accordingly, various strategies have been employed to tailor the phase transformation behavior of AFE materials in order to improve their performances. Due to their relatively poor electrical strength (low breakdown fields), most PZ-based orthorhombic AFE ceramics are broken down before a critical switching field can be applied. As a consequence, the electric-field-induced transition between AFE and FE phase of only those AFE bulk ceramics, with compositions within tetragonal region near the AFE/FE morphotropic phase boundary (MPB), can be realized experimentally at room temperature. AFE materials with such compositions include (Pb,A)ZrO3 (A = Ba, Sr), (Pb1-3/2xLa x)(Zr1-yTiy)O 3 (PLZT x/(1-y)/y), (Pb0.97La0.02)(Zr,Sn,Ti) O3 (PLZST) and Pb0.99(Zr,Sn,Ti)0.98Nb 0.02O3 (PNZST). As compared to bulk ceramics, AFE thin and thick films always display better electric-field endurance ability. Consequently, room temperature electric-field-induced AFE-FE phase transition could be observed in the AFE thin/thick films with orthorhombic structures. Moreover, AFE films are more easily integrated with silicon technologies. Therefore, AFE thin/thick films have been a subject of numerous researches. This review serves to summarize the recent progress of PZ-based AFE materials, focusing on the external field (electric field, hydrostatic pressure and temperature) dependences of the AFE-FE phase transition, with a specific attention to the performances of AFE films for various potential applications, such as high energy storage, electric field induced strains, pyroelectric effect and electrocaloric effect. © 2014 Elsevier Ltd.

In this work, (1 - x)(Na0.5Bi0.5)TiO 3-xSrTiO3 (abbreviated as NBT-xST, x = 0%, 20%, 26%, 30%, 36%) thick films with 3 wt% 3Bi2O3-2Li2O glass addition were successfully fabricated via a screen printing method. The dielectric properties and energy-storage performances were studied systematically. It was found that the dielectric constant of NBT-xST films decreased with ST content increasing and that the films exhibited relaxor behavior. The highest recoverable energy density of 2.7 J/cm3 under 600 kV/cm was achieved in the sample with 30 mol% ST content, which also displayed good energy-storage stability in the temperature range from room temperature to 200 C. Simultaneously, the leakage current was greatly reduced due to the addition of ST. © 2013 Elsevier B.V. All rights reserved.

In this letter, orthorhombic Pb(Nb,Zr,Sn,Ti)O3 (PNZST) and tetragonal (Pb,La)(Zr,Sn,Ti)O3 (PLZST) antiferroelectric (AFE) thin films were deposited on LaNiO3/Pt(111)/TiO2/SiO 2/Si(100) substrates via a sol-gel method. The electrocaloric effect (ECE) of PNZST and PLZST films originated from phase transition between AFE and ferroelectric were studied, based on their pyroelectric results. A large tunable ECE near room temperature was realized in these films under the function of electric field. As the applied electric field increased, the temperature corresponding to the peak of ECE was decreased for the orthorhombic PNZST films, while the temperature was increased for the tetragonal PLZST films. The maximum ECE of 0.040 K · cm/kV in PNZST films and 0.048 K · cm/kV in PLZST films was received at 323 and 305 K, respectively. The results indicated that AFE thin films had the potential for application in tunable cooling devices near room temperature. © 2014 AIP Publishing LLC.

1.8 -μm-(Pb0.97La0.02)(Zr0.95-xSn xTi0.05)O3 antiferroelectric thick films with orthorhombic (x 0.05 and 0.25) and tetragonal (x 0.40) structure were deposited on platinum-buffered silicon substrates by using a chemical solution way. All the films had a uniform microstructure with pure perovskite phase. With increasing x value, dielectric constant and critical electric breakdown field of the thick films were gradually increased, while their saturated polarizations were decreased. As a result, their maximum recoverable energy-storage density was increased for the thick films with larger x values. A huge recoverable energy-storage density of 56 J/cm3 was obtained in antiferroelectric thick films with x 0.40. Moreover, a good temperature-dependent stability of the energy storage was obtained in the all films from 20 to 120 °C. © 2013 AIP Publishing LLC.

This paper studies the modelling and identification problems for multi-input single-output (MISO) systems with colored noises. In order to obtain the unbiased recursive estimates of the systems, this paper presents a recursive least squares (RLS) identification algorithm based on bias compensation technique. The basic idea is to eliminate the estimation bias by adding a correction term in the least squares (LS) estimates, a set of stable digital prefilters are suitably designed to preprocess the input sampled data from multi-input channels for the purpose of getting the bias term arisen by colored noises in LS estimates, and further to derive a bias compensation based RLS algorithm. The performance of the developed method is both analyzed theoretically and shown by means of simulation results. © 2011.

Apoptosis plays an important role in various biological processes and acts as a host defending mechanism by which infected cells are eliminated to restrict the virus propagation scale. Bax is a crucial pro-apoptotic protein, which mediates the release of cytochrome c from mitochondrion to cytosol in mammalian. However, its role in invertebrate is still obscure. Here, a novel pro-apoptotic protein gene was identified from hemocytes of red swamp crayfish. There was a Bcl-2 domain in the C-terminus of Pc-Bax, which possessed 497 amino acids residues. And an important transmembrane region existed in the C-terminus of Pc-Bax, which implied that Pc-Bax located in mitochondrial membrane. Besides, Pc-Bax was expressed at a relative high level in hemocytes, and a relative low expression levels in hepatopancreas, gills, and intestine. In hemocytes, Pc-Bax transcript was rapidly up-regulated from 12 h to 36 h after WSSV infection. And there was the same trend for Pc-Bax protein expression level in hemocytes after WSSV infection. Results of qRT-PCR testing for VP28 gene showed WSSV replication was obviously enhanced after Pc-Bax knockdown. Meantime, hemocytes apoptosis was suppressed in Pc-Bax knockdown crayfish after WSSV injection, compared with the dsGFP injection group and normal group. Taken together, these results revealed that crayfish hemocytes apoptosis scale was enhanced to suppress WSSV replication by up-regulating Bax protein expression level after WSSV infection. © 2016 Elsevier Ltd.

We investigate electric-field-driven transport of electrons in metallic as well as amorphous high-temperature superconductors by using the verified transition-rate approach which has been successfully adopted to study the critical transport of glassy solid helium in very low temperature environment. The critical temperatures related to the nearly frictionless transport of electrons were found to be directly relevant to the (onset) phase-transition temperature of high-temperature superconductors (like MgB 2 and Hg1-xPbxBa2Ca2Cu3O8δ [Hg(x Pb) 1:2:2:3]) after selecting specific activation energies and activation volumes. © 2010 Elsevier B.V.

We investigated the p-electron ferromagnetism in alkaline earth doped AlAs by using first-principles calculations. The modified Becke and Johnson potential is used to give a much more reasonable semiconductor gap. Our results demonstrate that ferromagnetic phase is always energetically favorable than the antiferromagnetic and nonmagnetic ones for all considered compounds. Magnetic moments are mainly attributed to the partly filled anionic p states. Especially, half-metallic ferromagnetism has been obtained for Ca- and Sr-doped AlAs, which may be promising for spintronic applications. The calculated results are also useful for understanding of the origin of ferromagnetism in diluted magnetic semiconductors. © 2012 American Institute of Physics.
