Determination of air permeability of soil or material in protection from flooding in urban construction

open access: yesВестник СибАДИ
Introduction. Permeability of soils and materials is an important parameter in flood protection in urban construction. Any liquid or gas is called a fluid when it moves by filtration through porous soil or material.

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

open access: yesAdvanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

A STUDY ON A MEASUREMENT SYSTEM FOR DETERMINING BULK DENSITY OF UNSATURATED SOILS BASED ON SOIL GAS PERMEABILITY

open access: yesEngenharia Agrícola
Soil compaction alters soil structure, reduces soil air permeability, and adversely impacts crop growth. However, the rapid field detection of soil compaction remains a significant technical challenge.

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

open access: yesAdvanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

The determination of air-permeability of soils.

open access: yesNetherlands Journal of Agricultural Science, 1960
An improved apparatus for determining air-permeability of soils at constant pressure gradient is described; its merits are discussed in the light of existing literature. Some experimental results obtained with a sandy soil under different tillage conditions are given and discussed. (Abstract retrieved from CAB Abstracts by CABI’s permission)
