Application of trace analysis and chemometrics to environmental problems
… followed by the analysis of the products of controlled degradation. It was found that extraction of the humic acid caused some changes to occur in its structure and that degradation, however controlled, was not reproducible. It was finally discovered that the treatability of the coloured …

Study of Si(Al)CN functionalized carbon nanotube composite as a high temperature thermal absorber coating material
… 400°C in air. PDC, which are obtained by the controlled degradation of certain organosilicon polymers however exhibit high temperature stability (upto approx. 1400 °C). To this end, a hybrid composite material consisting of PDC functionalized CNT is of interest as it can combine the unique …

Characterization of Laser Modified Surfaces for Wood Adhesion
The controlled degradation of wood surfaces with infrared light from a CO2 pulsed laser facilitated adhesion without the use of additional resins. Laser modification creates a surface phenomenon that physically and chemically alters the natural biopolymer organization of lignocellulosic materials …
