Soil Nutrient Detection for Precision Agriculture Using Handheld Laser-Induced Breakdown Spectroscopy (LIBS) and Multivariate Regression Methods (PLSR, Lasso and GPR).
TL;DR: The potential of handheld LIBS for the determination of the total mass fractions of the major nutrients Ca, K, Mg, N, P and the trace nutrients Mn, Fe was evaluated and several methods of data pretreatment were investigated.

Investigations of Reactions of Selected Azaarenes with Radicals in Water. 1. Hydroxyl and Sulfate Radicals
TL;DR: In this article, the authors studied the reaction behavior of binuclear azaarenes with carbonate radicals and showed that excited states in the reaction mechanism caused a shift of the oxidation center from the benzene to the pyridine rings.

Ion mobility spectrometric investigation of aromatic cations in the gas phase.
TL;DR: Experimental evidence is presented suggesting the formation of pi-stacks with a transition toward modified pi-Stacks with increasing cluster size, and the distance between monomeric units in dimeric and oligomeric ions was obtained.

Investigation on the photoreactions of nitrate and nitrite ions with selected azaarenes in water
TL;DR: The photoreactions of selected azaarenes with nitrate and nitrite ions were investigated under irradiation at lambda = 313 nm and led to several photochemical reactions forming mainly hydroxyl radicals and nitrogen oxides.

TL;DR: This work presents a novel concept of an ESI source facilitating the stable operation of the spectrometer at flow rates between 10 μL min−1 and 1500 μLMin−1 without flow splitting, advancing the T-cylinder design developed by Kurnin and co-workers.
