The Thermal degradation of Bisphenol A Polycarbonate in Air [PDF]

open access: yes, 2005
The thermal degradation of polycarbonate in air was studied as a function of mass loss using TGA/FTIR, GC/MS and LC/MS. In the main degradation region, 480–560 °C, the assigned structures of smaller molecules and linear molecules that evolved in air were

Characterizing degradation of palm swamp peatlands from space and on the ground: an exploratory study in the Peruvian Amazon [PDF]

open access: yes, 2017
Peru has the fourth largest area of peatlands in the Tropics. Its most representative land cover on peat is a Mauritia flexuosa dominated palm swamp (thereafter called dense PS), which has been under human pressure over decades due to the high demand for

Lignin‐degrading enzymes [PDF]

open access: yesThe FEBS Journal, 2015
A main goal of green biotechnology is to reduce our dependence on fossil reserves and to increase the use of renewable materials. For this, lignocellulose, which is composed of cellulose, hemicellulose and lignin, represents the most promising feedstock.

Degrading Lists

open access: yesProceedings of the 22nd International Symposium on Principles and Practice of Declarative Programming, 2020
We discuss the relationship between monads and their known generalisation, graded monads, which are especially useful for modelling computational effects equipped with a form of sequential composition. Specifically, we ask if a graded monad can be extended to a monad, and when such a degrading is in some sense canonical. Our particular examples are the
