The hierarchical zeolite is one of the most promising materials for catalytic applications. However, effect its pore connectivity on behaviors and coke formation has not clearly been revealed. In this contribution, we demonstrate visualization mesopore architecture in three-dimensional perspectives together with network pore-opened mordenite (MOR), fabricated by seed-assisted template-free synthesis followed fluoride treatment via electron tomography (ET) technique. Interestingly, zeolites...
Abstract The increasing prevalence of methicillin-resistant Staphylococcus aureus (MRSA) emphasises the urgent need for novel antimicrobial agents as alternatives to antibiotics. Bacteriophage therapy is one most promising strategies. Here, we isolated and comprehensively characterized a phage, vB_SauM_VL10 (VL10), from urban sewage. VL10 genome displays 141,746 bp linear double-stranded DNA, containing 193 open reading frames lacking tRNA, virulence, or antibiotic resistance genes....
Chlamydia is a known pathogen in both saltwater and freshwater crocodiles. However, the exact species/strain has not been clearly identified. In this study, we successfully cultivated Siamese crocodile McCoy cells at temperature of 30°C. Electron microscopy; phylogeny based on nine conserved taxonomically informative markers, ompA, or seven housekeeping genes; whole-genome sequencing analysis isolate confirmed identity as new member genus Chlamydia, species that name crocodili.
Pseudomonas aeruginosa is a notable nosocomial pathogen that can cause severe infections in humans and animals. The emergence of multidrug resistant (MDR) P. has motivated the development phages to treat infections. In this study, novel phage, vB_PaeS_VL1 (VL1), was isolated from urban sewage. Phylogenetic analyses revealed VL1 species genus Litunavirus subfamily Migulavirinae. virulent phage as no genes encoding lysogeny, toxins or antibiotic resistance were identified. therapeutic...
Aeromonas dhakensis stands out as the most potent species causing a range of human diseases. This research marks pioneering effort in isolating and characterizing virulent phages targeting A. dhakensis. Only AM isolate among isolates showed compatibility for phage isolation was identified Computational analysis presence virulence factors antimicrobial resistance genes AM. Phage conducted using this particular strain host, resulting four phages: vB_AdhM_DL, vB_AdhS_TS3, vB_AdhM_TS9,...
The nanostructured free-standing NiAl-MOR-CNTs electrocatalysts containing carbon nanotubes (CNTs) deposited on mordenite (MOR) zeolite/NiAl-layered double hydroxide (NiAl-LDH) have been successfully fabricated. Initially, the core-shell NiAl-LDH-MOR with hierarchical structures was observed via an aqueous miscible organic solvent treatment process to deposit nanosized NiAl-LDH homogeneously a zeolite surface. synthesized composites were calcined produce highly dispersed metal oxides...
A novel fluorescent sensor composed of bis-hydrazino naphthalimide decorated with a pillar[5]arene motif demonstrated highly selective sensing nonanal and octanal via self-assembled supramolecular polymeric nanoparticles.
Deposition of CuNPs on silver film gives rise to the formation active Ag-Cu interfaces leading dramatic enhancements in antibacterial activity against Escherichia coli. Transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDAX) analyses reveal that are covered a thin Cu2O shell, while photoelectron measurements (XPS) Ag samples contain significant amounts Ag2O. XPS show deposition films leads photoactive Ag2O-Cu2O heterostructure. Following Z-scheme mechanism,...
Phage-based biocontrol is an alternative method for preventing and controlling the occurrence of Pseudomonas spp. in food products. However, use bacteriophages to control heat-stable protease fluorescens still rare. The objectives this study were isolate lytic P. fluorescens, evaluate their efficacy at laboratory level. Among these strains, only one phage, ΦTIS1, was isolated by using TISTR 1887 as host. Further analysis electron microscopy indicated that ΦTIS1 belongs Myoviridae family....
We describe here a method to decrease particle size of nanoparticles synthesized by miniemulsion polymerization. Small or nanocapsules were obtained generating an osmotic pressure induce the diffusion monomer molecules from dispersed phase before polymerization upper oil layer. The reduction is dependent on difference in concentration and layer solubility water. By labeling emulsion droplets with copolymer stearyl methacrylate polymerizable dye, we demonstrated that migration hexadecane...
Abstract Bifunctional acid‐base catalysts have been developed by fabricating core‐shell faujasite@aqueous miscible organic‐layered double hydroxides (FAU@AMO‐LDHs) composites via the growth of AMO‐LDHs on zeolite surfaces. Interestingly, adjusting acid/base properties composites, one‐pot synthesis ethyl trans ‐α‐cyanocinnamate deacetalization‐Knoevenagel reaction can be achieved up to 90% yield. In contrast, almost no desired products observed in cases isolated zeolites and AMO‐LDHs,...
Electrochemical water oxidation utilizing bimetallic CoNi‐Tz (Tz = 1,2,4‐triazole) framework is explored. Initially, possesses active tetrahedral Co center and electron‐mediated octahedral Ni chain. After performing an electrochemical activation, the partial structural transformation on occurs. This leads to generation of excessive centers which can promote catalytic activity framework. The activated catalyst displays a remarkably low OER overpotential 293 mV at current density 10 mA cm‐2...
A facile, green, and economical method for the scalable synthesis of hydrophilic copper‐triazole metal‐organic frameworks (Cu‐trz) is demonstrated. Numerous open metal sites within highly crystalline porous structure Cu‐trz are generated through mild thermal activation, enabling its application in liquid‐phase ethanol dehydration under ambient conditions. The with distinct crystallinity particle sizes were achieved by modifying process. high framework plays an exclusive role enhancing water...
Phage therapy has emerged as a potential solution to the issue of multidrug-resistant bacteria. In this study, novel bacteriophage vB_AdhS_M4 , which infects Aeromonas dhakensis, was isolated. A. dhakensis strains were isolated from water samples in Thailand and identified by biochemical 16S rDNA sequence analysis. Four isolates, namely AM, NGP8, AK3, SBKN4 used hosts for phage isolation. Only 1 phage, vB_AdhS_M4, obtained using AM host. morphology, host range, one-step growth curve, pH...

This study is the first characterise apply bacteriophages heat-stable protease producing Pseudomonas mosselii. We isolated protease-producing evaluated its proteolytic activity. Fourteen strains three reference strains, P. aeruginosa TISTR 2370, fluorescens 2237, 1887, produced a clear zone of casein hydrolysis on skim milk agar, all except 1887 harbored aprX gene. All 17...
Aeromonas dhakensis is the most virulent species in tropical and subtropical areas abundant aquatic environments. This first study to isolate characterize lytic phages against A. from water. Of isolates, only AM could be used phages. strain was identified as dhakensis. In silico detection of antimicrobial resistance genes virulence factors corresponding main bacterial determinants were observed AM, which then host for phage isolation.
