A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

Advanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

PENENTUAN NILAI KONDUKTIVITAS HIDROLIK TANAH TIDAK JENUH MENGGUNAKAN UJI RESISTIVITAS DI LABORATORIUM

Jurnal Teknik Pengairan, 2013
Electrical resistivity can be used to identify geotechnical parameters such as water content, liquid limit, plastic limit and unit weight. It is known that the hydraulic conductivity values can be predicted based on soil properties, so that should be ...

Formulating surrogate pumping test data sets to assess aquifer hydraulic conductivity

Journal of Hydrology X, 2018
A hypothesis to estimate hydraulic conductivity from surrogate pumping tests formulated using routinely monitored pumping rates and hydraulic heads is tested. The data set of a surrogate pumping test contains only a few late-time drawdowns represented by

Capillary barrier effect on the response of residual slope to rainfall infiltration [PDF]

, 2008
Rainfall-induced slope failure is a common problem in areas covered by residual soil in tropical countries. The soil exists in unsaturated condition as ground water table is located well below the ground surface.

Droplet Electricity Generators With Maximized Energy Collection Zone Enabled by Aloe‐Inspired Midrib and Cuticle

Advanced Materials, EarlyView.
An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

The response of hydraulic conductivity to air-trapped saturation in a dissolution process of trapped-air in quasi-saturated fine sands media

Shuiwen dizhi gongcheng dizhi
The hydraulic conductivity of a quasi-saturated aquifer decreases with the increase of air-trapped saturation, but it is difficult to obtain a continuous data on air-trapped saturation through the traditional displacement experiments due to limitations ...

Laboratory study on the effects of hydraulic and granulometric parameters on the response of granular soil to internal erosion [PDF]

, 2019
Erosion is a major environmental problem to agricultural land as well as to civil engineering infrastructures. Rainwater infiltration into granular soils can lead to the migration of fine particles by suffusion.

Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites

Advanced Materials Interfaces, EarlyView.
Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.

Hydraulic Conductivity of a Firn Aquifer in Southeast Greenland

Frontiers in Earth Science, 2017
Some regions of the Greenland ice sheet, where snow accumulation and melt rates are high, currently retain substantial volumes of liquid water within the firn pore space throughout the year.
