Effect of biochar on soil structure – review

open access: yes, 2018
Soil structure is usually defined as the spatial arrangement of soil particles and soil voids (i. e. soil pores), which may also be defined as the spatial distribution of soil properties.

Heteroatom‐Engineering Promoted Co9S8 Bi‐functional Electrocatalyst for Hydrazine‐Assisted Hydrogen Production at Industrial Current Density

open access: yesAdvanced Functional Materials, EarlyView.
Fe and P co‐doped Co9S8 nanocorals (Fe, P‐Co9S8) are successfully synthesized by a heteroatom engineering strategy, which exhibit outstanding bifunctional electrocatalytic performance for both the hydrogen evolution reaction (HER) and hydrazine oxidation reaction (HzOR).

Assessing soil structure in organically farmed soils [PDF]

open access: yes, 2002
This report was presented at the UK Organic Research 2002 Conference. Soil structure was assessed in over 90 fields (organic and conventionally farmed) covering mixed, stockless and pasture farming systems. A combination of spade and an objective scoring

Mimicking Block Copolymer Self‐Assembly with One‐Pot Synthesized Polyphosphoester Gradient Copolymers

open access: yesAdvanced Functional Materials, EarlyView.
Degradable Polyphosphoester (PPE) gradient copolymers (GCPs) are synthesized via one‐pot copolymerization. We show that GCPs self‐assemble into nanostructures like polymersomes, effectively mimicking the behavior of traditional BCPs. The gradient strength is key, with softer gradients favoring micelles.

The rheometry approach in modern soil studies: a review

open access: yesБюллетень Почвенного института им. В.В. Докучаева
Digital soil rheometry is a relatively new and rapidly developing research direction that currently occupies a small niche in soil and agrophysics studies.

Vulnerability of soil aggregates in relation to soil properties

open access: yesPlant, Soil and Environment, 2002
Stability of soil structure represents an indicator of soil quality. The aim of this paper was to assess the effect of soil properties on structure vulnerability in an Orthic Luvisol.

Disparate responses of above- and belowground properties to soil disturbance by an invasive mammal [PDF]

open access: yes, 2014
Introduced mammalian herbivores can negatively affect ecosystem structure and function if they introduce a novel disturbance to an ecosystem. For example, belowground foraging herbivores that bioturbate the soil, may alter process rates and community ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Can soil properties of Fluvisols be influenced by river flow gradient?

open access: yesActa Fytotechnica et Zootechnica, 2018
The occurrence of Fluvisols is associated with the rivers, which means that their properties can be greatly influenced by the fluvial activity of the rivers.

Efeitos de sistemas de cultivo na densidade e macroporosidade do solo e no desenvolvimento radicular do milho em latossolo roxo Effects of tillage systems on bulk density, aeration porosity and root development of corn in a typic haplorthox soil

open access: yesPesquisa Agropecuária Brasileira, 1999
Neste trabalho foram estudados os efeitos imediato e residual de dois sistemas de preparo na densidade e macroporosidade do solo e no desenvolvimento radicular do milho (Zea mays L.), em camadas estruturalmente estabilizadas de um Latossolo Roxo, mantido
