Voltammetric Studies of Nitrate Reduction at Boron‐Doped Diamond Thin‐Film Electrodes of Different Microstructure

open access: yesElectroanalysis, Volume 38, Issue 5, May 2026.
The electrochemical reduction of nitrate at polycrystalline boron‐doped diamond (BDD) electrodes using three different microstructures was studied. The reduction of nitrate proceeded similarly on the three BDD electrode types in terms of onset and peak potentials in 0.1 M Na2SO4.

Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 747-753, May 2026.
Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...

Korea Rediscovers Organic Agriculture [PDF]

open access: yes, 2009
Korea will host the next Organic World Congress in 2011. The early pioneers of organic farming looked to the East for both evidence and inspiration. Korea now appears to be in the process of rediscovering its organic farming heritage.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 2254-2341, May 2026.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Techno-economic and life cycle greenhouse gas assessment of green ammonia produced by low-pressure Haber-Bosch process

open access: yesEnergy Nexus
Green ammonia can be used as an energy storage carrier and a sustainable chemical. To improve the competitiveness of green ammonia, two power-to-ammonia (PtA) processes integrated with low-pressure (LP) and ultra-low-pressure (ULP) Haber-Bosch (HB ...

Underestimation of Future Agricultural Soil N2O Emissions and Abatement Needs

open access: yesGlobal Change Biology, Volume 32, Issue 5, May 2026.
Agricultural soils are a major source of rising atmospheric N2O concentrations, yet future emission projections remain highly uncertain. Most assessments rely on static emission factors (EFs) that assume constant N2O release per unit of fertilizer, overlooking how climate change and evolving fertilizer practices may alter these factors. Using a physics‐
