Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

Advanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Biodegradation and characterization study of compostable PLA bioplastic containing algae biomass as potential degradation accelerator

, 2021
This study demonstrated the degradation behavior of poly(l-lactic acid) (PLA)/algae biomass biocomposites under abiotic (58 ± 2°C) and at thermophilic composting conditions (58 ± 2°C). In the biodegradation study, laboratory synthesized, custom-made poly(

Oxidative degradation of polylactide (PLA) and its effects on physical and mechanical properties [PDF]

, 2014
The thermo-oxidative degradation of polylactide (PLA) films was studied between 70 and 150 C. It was shown that the oxidative degradation of PLA leads to a random chain cission responsible for a reduction of the molar mass.
