Mechanical performance of glass-based geopolymer matrix composites reinforced with cellulose fibers [PDF]
, 2018 Glass-based geopolymers, incorporating fly ash and borosilicate glass, were processed in conditions of high alkalinity (NaOH 10-13 M). Different formulations (fly ash and borosilicate in mixtures of 70-30 wt% and 30-70 wt%, respectively) and physical ...

Online monitoring method of degree of cure during non-isothermal microwave curing process
Materials Research Express, 2018 Curing rate is the variation rate of degree of cure with time, which is a crucial issue in the curing process of composite structures since it has a significant influence on the generation of voids and residual stresses. In this paper, an online monitoring method of degree of cure was presented based on refractive index measurement.

Pediatric Blood &Cancer, EarlyView.ABSTRACT The pediatric hematology‐oncology fellowship training curriculum has not substantially changed since its inception. The first year of training is clinically focused, and the second and third years are devoted to scholarship. However, this current structure leaves many fellows less competitive in the current job market, resulting in ...

Rapid microwave processing of epoxy nanocomposites using carbon nanotubes [PDF]
, 2013 Microwave processing is one of the rapid processing techniques for manufacturing nanocomposites. There is very little work focussing on the addition of CNTs for shortening the curing time of epoxy nanocomposites. Using microwave energy, the effect of CNT
