In this review, we summarize recent reports on the synthesis of various nanoporous carbon materials. Many materials having variable pore sizes and structures have been synthesized using appropriate nanostructured silica as templates. Nanoporous carbons with high volumes uniform produced sol gel Mesoporous several different mesoporous such MCM-48, HMS, SBA-15, MSU, MCF Some these were successfully used adsorbents for bulky pollutants electrodes supercapacitors fuel cells.
Carbon nanocoils with nanometer-thick graphitic fibers (see picture) were synthesized by the simple heat treatment of nanocomposites a carbon precursor, silica, and transition-metal salt. The exhibited high surface area highly graphitized structure. then successfully applied as catalyst supports for direct methanol fuel cell electrodes.

The origin of the excellent electrocatalytic performance PtRu alloy catalysts supported on newly synthesized carbon nanocoil supports was investigated. Among three commercially available materialsVulcan XC-72, multiwall nanotube, and activated carbon, Vulcan XC-72-supported catalyst exhibited best catalytic performance. Carbon nanocoils with variable surface areas crystallinity were employed as for 60 wt % Pt/Ru (1:1) catalysts. all these better compared to XC-72 carbon. In particular,...
Abstract Alzheimer’s disease (AD) is a chronic neurodegenerative disorder and the leading cause of dementia, but therapeutic treatment options are limited. Taurine has been reported to have neuroprotective properties against including AD. The present study aimed investigate effect taurine in AD mice by functional molecular imaging. To elucidate glutamate alterations taurine, was administered 5xFAD transgenic from 2 months age, known apear amyloid deposition. Then, we performed positron...
The development of intracardiac echocardiography (ICE) has enabled fluoroless atrial fibrillation (AF) ablation using three-dimensional electroanatomical mapping systems. However, cryoballoon (CBA) remains challenging, mainly because the lack a visual system. Hence, this study aimed to investigate safety and efficacy CBA for AF under ICE guidance.Patients (n = 100) who underwent paroxysmal were randomly assigned zero-fluoroscopic (Zero-X) conventional groups. Intracardiac was used guide...
Importance Discontinuation of oral anticoagulant treatment is common in clinical practice due to concerns about bleeding, even for procedures with minimal low bleeding risk. Objective To explore whether perioperative discontinuation factor Xa inhibitors associated major and thromboembolic events patients atrial fibrillation (AF) undergoing Design, Setting, Participants This prospective, multicenter, single-arm cohort study conducted Korea included AF who planned undergo a procedure risk...
Nanocrystalline TiO2 photocatalysts: We have synthesized highly crystalline nanocrystals by the controlled sol–gel reaction of titanium tetraisopropoxide in aqueous solution at room temperature. Anatase nanorods, spherical anatase nanocrystals, and rutile nanorods were (see HRTEM image latter). The show much better photocatalytic activities for Eosin Y, phenol photooxidation, E. coli inactivation than Degussa P-25. Supporting information this article is available on WWW under...
Abstract The aim of this paper is to critically assess the extent which concept second modernity and reflexive modernization proposed by Beck Grande relevant East Asia. Concepts such as driving forces, human agency, objective‐structural versus cultural‐discursive dimensions, radicalizing deficiencies aspects modernity, push pull factors are used clarify basic conditions historical transformation. Utilizing these conceptual schemes, has advanced following central claims: 1) Second...
The effects of the annealing temperature on structural and chemical properties soluble-processed zinc-tin-oxide (ZTO) films were examined by transmission electron microscopy, atomic force high resolution X-ray reflectivity, photoelectron spectroscopy. density purity resulting ZTO channel layer increased with increasing temperature, whereas oxygen vacancy defect decreased. As a result, device performance soluble thin film transistors (TFTs) was improved at higher temperature. Although 300...
2′-Hydroxycinnamaldehyde (HCA) was isolated from Cinnamomum cassia Blume (Lauraceae) and 2′-benzoyloxycinna-maldehyde (BCA) prepared by the reaction of HCA benzoyl chloride. BCA strongly inhibited in vitro growth 29 kinds human cancer cells vivo SW-620 tumor xenograft without loss body weight nude mice. prevented adherence to culture surface but did not inhibit oncogenic K-Ras processing, implying its antitumor mechanisms at cellular level.
Although the incidence of bleeding complications during extracorporeal membrane oxygenator (ECMO) support has decreased in various trials, is still most fatal complication. We investigated ideal dosage and efficacy nafamostat mesilate for use with ECMO patients acute cardiac or respiratory failure. assessed 73 consecutive who received due to failure between January 2006 December 2009. To evaluate mesilate, we divided into 2 groups according anticoagulants used support. All group were male a...
This study examined the structural, chemical, and electrical properties of solution-processed (Zn,Sn)O3 (ZTO) films with various Sn/[Zn+Sn] ratios for potential applications to large-area flat panel displays. ZTO a Zn-rich composition had polycrystalline wurtzite structure. On other hand, Sn-rich exhibited rutile structure, where Zn atom was speculated replace Sn site, thereby acting as an acceptor. In intermediate regions (Sn/[Zn+Sn] ratio from 0.28 0.48), amorphous even after annealing at...
Extracorporeal membrane oxygenation (ECMO) is a useful treatment for refractory out-of-hospital cardiac arrest (OHCA). However, little known about the predictors of survival and neurologic outcome after ECMO. We analyzed our institution's experience with ECMO OHCA evaluated ECMO.This was retrospective review medical records 23 patients who were treated due to that unresponsive conventional cardiopulmonary resuscitation, between January 2009 2014.Our team activated within 10 min OHCA, 30-day...
To develop a system with which to quantify objectively the heterophoria be measured throughout eye movement experiments. This study compared precision, resolution and accuracy characteristics of limbus tracking alternate cover test Maddox rod.Precision testing was performed using each technique binocularly-normal subjects at different sessions. Resolution between three systems. The or phoria from 40 cm/16 inches rod during sustained convergence-induced adaptation experiment physical...
This study aimed to identify the determinant factors for clinical outcomes and survival rates of patients with cardiac arrest (CA) concurrent acute myocardial infarction (AMI) who underwent extracorporeal cardiopulmonary resuscitation (ECPR) using membrane oxygenation (ECMO).We retrospectively evaluated 37 admitted our emergency department between January 2006 August 2012 AMI-induced CA treated ECPR during ongoing continuous chest compressions.Mean patient age was 61.4 ± 11.3 years, 27 (73%)...
Background Stroke and thromboembolic events may still occur in "clinically low-risk" atrial fibrillation (AF) patients as categorized by CHA2DS2-VASc score. Our aim was to assess the proportion of using a nongender (ie, CHA2DS2-VA) score 0 1 among who experienced AF-associated stroke identify markers associated with patients. Methods Results We retrospectively recruited nonvalvular AF embolic between 2013 2016 from 9 institutes Korea. CHA2DS2-VA at time were analyzed compared without stroke....
Cryoballoon ablation (CBA) is considered an effective rhythm control treatment for atrial fibrillation (AF) and increasing exponentially. However, data regarding the efficacy safety of CBA in elderly patients are limited. A total 2,652 (55.2% with non-paroxysmal AF) from Korean registry database follow-up ≥12-months after de novo were divided into 2 groups based on age (<75 ≥75 years old). Procedure related complications clinical outcomes compared. Compared to group (n=2,403), (n=249) had...
