Latex beads are used as a combined template and porogen in the fabrication of monolithic silica containing hierarchy pores. Prefabricated core/shell particles, prepared by layer-by-layer assembly zeolite (silicalite) nanoparticles onto spherical latex templates, assembled into macroscopic close-packed structures. Calcination removes all organic components causes densification inorganic structure producing macroporous which both pore size wall thickness can be varied.
Silicalite nanoparticles and starch gel templates have been used to fabricate zeolite materials with a hierarchical micro/meso/macropore organization. Two methods were investigated. First, macroporous monoliths consisting of continuous mesoporous framework microporous silicalite prepared by incorporating 50-nm-sized into freshly viscous gels, followed air-drying calcination. Macropore sizes between 0.5 50 μm achieved varying the amount starch/silicalite weight ratio. Mesoporous thin films...
There are a number of strategies available for extending the length scale structural organization in inorganic materials. Those that involve assembly nanoparticles into materials with higher-order architecture collectively termed nanotectonics. In this review, we highlight one possible approach involves template-directed preformed nanoparticle building blocks. The inspiration use particles arises part from studies certain biomineral structures, some general aspects which summarized. Several...
Typically, SO2 unavoidably deactivates catalysts in most heterogeneous catalytic oxidations. However, for Pt-based catalysts, exhibits an extraordinary boosting effect propane oxidation, but the promotive mechanism remains contentious. In this study, situ-formed tactful (Pt–S–O)-Ti structure was concluded to be a key factor Pt/TiO2 with substantial tolerance ability. The experiments and theoretical calculations confirm that high degree of hybridization orbital coupling between Pt 5d S 3p...
Ordered macroporous zeolite fibres are prepared from the infiltration of swollen bacterial supercellular threads with as-synthesized silicalite nanoparticles.
Catalytic ozone (O3 ) decomposition at high relative humidity (RH) remains a great challenge due to the catalysts poison and deactivation under humidity. Here, we firstly elaborate role of water activation corresponding mechanism promoted O3 over three-dimensional monolithic molybdenum oxide/graphdiyne (MoO3 /GDY) catalyst. The MoO3 /GDY reaches up 100 % humid condition (75 RH) room temperature, which is 4.0 times as that dry conditions, significantly surpasses other carbon-based...
Particulate matter, represented by soot particles, poses a significant global environmental threat, necessitating efficient control technology. Here, we innovatively designed and elaborately fabricated ordered hierarchical macroporous catalysts of Ce0.8Zr0.2O2 (OM CZO) integrated on catalyzed diesel particulate filter (CDPF) using the self-assembly method. An oxygen-vacancy-enriched catalyst (VO-OM CDPF was synthesized subsequent NaBH4 reduction. The VO-OM CZO exhibited markedly enhanced...

Low-cost and accurate measurement of fluid viscosity based on a pressure-driven flow in digital-printed microfluidics.
This article introduced one new teaching method, applies this method in time, does not look like traditional the entire process to have gradualness, but according C language's characteristic and humanity's cognition rule, language divides into three stages. Utilizes different media each stage teacher, lets student study power goal stage, guides realize that pondered. only causes knowledge memory be profound, moreover can train good begin custom, strengthens program ability, thus changes...
Abstract The earth pressure and deformation characteristics of a geogrid reinforced soil retaining wall were monitored during for period 1.5 years after construction. Both vertical lateral stresses recorded with vibrating-wire cells, the reinforcement deformations measured using flexible displacement sensors. maximum foundation along wall’s reinforcements occurred at center reinforcement, gradually decreasing towards front back ends. within is non-linear height, value less than theoretical...
The permanent magnet electrodynamic wheel system is a competitive alternative for the implementation of maglev car due to its levitation–propulsion integration ability. However, temperature rise conductive plate may deteriorate operational performance even result in suspension failure, which underlines importance thermal analysis. In this article, thermal-force coupling analysis conducted by experiment combined with co-simulation method. First, heat resource generated power loss obtained and...

Crystal tectonics involves the chemical-based construction and self-assembly of organized materials from solid-state building blocks, such as inorganic nanoparticles. This Perspective describes, through a series examples, how architectural complexity with higher-order structure can be controlled by organic templating, interparticle molecular recognition mesophase transformation. It is shown coupling synthesis over multiple length scales leading to new horizons in chemistry matter.
Ecocompensation projects (EPs) have two primary objectives: environmental protection and the livelihood maintenance of farmers. Farmers’ ecocompensation expectations (FEEs) are a key factor that affects whether design ecological policy is targeted at practical problems. This article divides FEEs into three dependent variables uses logistic regression multiple models to analyze influencing factors FEEs. The results questionnaire survey based on 259 farmers in area Returning Farmland Forest...

Sustained synthesis of methanethiol from the reaction CO/H2/H2S mixtures is reported and discussed. Surprisingly, unmodified α-Al2O3 gives best results for this selectivities >98% at CO conversions ca. 6% can be readily obtained (CO∶H2∶H2S = 4∶5∶1, 340 °C, total pressure 20 bar, 200 h−1). Reaction + H2 (CO∶H2 1∶1) in absence H2S using under comparable conditions a lower conversion (ca. 1.3%) with significant to methane (20%), methanol (28.5%) ethanol (21.1%). When added gas feedstock,...
