Quartzipsamments are environmentally fragile soils, being highly susceptible to water and wind erosion. Despite this, it seems that political economic issues favor the advancement of agriculture in these soils. Therefore, studies necessary for a better understanding soils minimize impacts land use. This work aims characterize morphological, physical–hydric, chemical properties under sandyzation...

Abstract Shale rocks are highly structurally and chemically heterogeneous, such that the pore structure–transport relationship is complex. Shales typically have porosity over many length-scales from molecular up to macroscopic fractures. This work utilizes gas overcondensation probe sizes micropores very large macropores all in same experiment without potential for damage due high pressures whe...

Pastures cover, in Brazil, around 165 million ha, most of them are at some degradation level. Recovering these pastures is essential. The objective this study was to evaluate the sensibility soil organic matter (SOM) and its physical attributes pasture different levels (1 4), Capoeiras 2) secondary Forest (Control). Samples were collected four depths (0.00-0.05, 0.05-0.10, 0.10-0.20 0.20-0.40 m...

New approaches for the engineering of 3D microstructure, pore modality, and chemical functionality hierarchically porous nanocarbon assemblies are key to develop next generation functional aerogel membrane materials. Here, interfacially driven assembly carbon nanotubes (CNT) is exploited fabricate structurally directed aerogels with highly controlled internal architectures, composed pseudo-mono...

The vertical change in the number of macropores causes a variation relative macroporosity (wf) and effective aggregate width (dag) over soil profile. Both parameters are used HYDRUS to represent this variation, increasing making automated calibration challenging. working hypothesis is that we can improve an analytical estimation wf dag developed previous research by inverse with meta-model for ...

Natural treefall gaps have a substantial role in maintaining soil and plant diversity old-growth forests. However, the amount of information on effects recovery physical chemical properties compacted soils is scarce. We tested hypothesis that natural accelerate restoration by enhancing biological microbial activity topsoil after period five years. Five years ground-based skidding operation Hyrc...

Graphite foil (GF) compressed from exfoliated graphite (EG) is a sealing material, which used in nuclear energy and the chemical industry. The preparation of complex process, includes intercalation graphite, water washing, thermal exfoliation pressing intermediate products. conditions significantly influence structure material its physicochemical properties. Thus, aim work was to reveal correla...

Spectroscopy on metal–organic framework (MOF) films and the molecular phenomena associated to them is mostly limited grazing incidence methods. To allow for transmission-based characterization highlight applicability of MOFs transparent substrates, UiO-67, UU-1, ZIF-8 are synthesized CaF2 windows. It revealed that growth UiO-67 MOF follows a Volmer–Weber mechanism using scanning electron micros...

Melt electrowriting (MEW) enables the electric field-assisted digital fabrication of precisely defined scaffold architectures micron-sized fibers. However, charge accumulation and consequent disruption precoded pattern by fiber bridging prevents controlled printing at small interfiber distances. This, together with periodical layer stacking characteristic for additive manufacturing, typically r...

Carbon monoliths were tested as electrodes for vanadium redox batteries. The materials synthesised by a hard-templating route, employing sucrose carbon precursor and sodium chloride crystals the hard template. For preparation process, both ball-milled together molten into paste which was hot-pressed to achieve polycondensation of monolith. resultant material pyrolysed in nitrogen at 750 °C, the...
