Hydraulic factors limiting the use of subirrigation in fine textured soils : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Philosophy in Agricultural Engineering at Massey University [PDF]

open access: yes, 1996
Subirrigation is a method of supplying water directly to the plant root zone under the ground surface by means of subsurfce drains which are also used to remove excess water from the root zone. Subsurface drainage systems are used to maintain appropriate

Porous Iridium Oxide Inverse Opal Catalysts Enable Efficient PEM Water Electrolysis

open access: yesAdvanced Materials, EarlyView.
Porous iridium‐based inverse opal (IrOx‐IO) structures are introduced as high‐performance, unsupported PEM‐WE anode catalysts. Their electrochemical behavior is analyzed through porosity/surface area tuning, voltage breakdown, and circuit modeling.

A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

open access: yesAdvanced 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 ...
