Simple data-driven context-sensitive lemmatization [PDF]

, 2006
Lemmatization for languages with rich inflectional morphology is one of the basic, indispensable steps in a language processing pipeline. In this paper we present a simple data-driven context-sensitive approach to lemmatizating word forms in running text.

Recent research trends in the rational design strategies of carbon-based electrocatalysts for electrochemical ammonia synthesis

Carbon Trends
Ammonia electrosynthesis is the most sustainable way to produce carbon-free hydrogen carriers, which would pave the way for the foreseen hydrogen economy and carbon neutralization as it has the potential to replace the conventional Haber-Bosch process ...

Tuning Product Distribution in Plasma‐Activated Water by Modifying Reactor Design

Chemistry–Methods, Volume 6, Issue 5, May 2026.
This study systematically compares plasma‐activated water reactor configurations for nitrogen fixation, demonstrating that reactor design, catalyst inegration, and gas flow govern product selectivity. Slurry reactor favor nitrate formation, whereas needle system promote ammonium production.

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

Electroanalysis, 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

PLANTS, 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 ...
