Polyimide (PI) films by chemical vapor deposition (CVD): Novel design, experiments and characterization [PDF]

open access: yes, 2007
Polyimide (PI) has been deposited by chemical vapor deposition (CVD) under vacuum over the past 20 years. In the early nineties, studies, experiences and characterization were mostly studied as depositions from the co-evaporation of the dianhydride and ...

A monolithic and flexible fluoropolymer film microreactor for organic synthesis applications [PDF]

open access: yes, 2019
A photocurable and viscous fluoropolymer with chemical stability is a highly desirable material for fabrication of microchemical devices. Lack of a reliable fabrication method, however, limits actual applications for organic reactions.

Restorative Dentistry: Dental composite depth of cure with halogen and blue light emitting diode technology [PDF]

open access: yes, 2009
Objectives To test the hypothesis that a blue light emitting diode (LED) light curing unit (LCU) can produce an equal dental composite depth of cure to a halogen LCU adjusted to give an irradiance of 300 mWcm–2 and to characterise the LCU's light outputs.

Simple one pot preparation of chemical hydrogels from cellulose dissolved in cold LiOH/urea [PDF]

open access: yes, 2020
In this work, non-derivatized cellulose pulp was dissolved in a cold alkali solution (LiOH/urea) and chemically cross-linked with methylenebisacrylamide (MBA) to form a robust hydrogel with superior water absorption properties.

Preliminary investigation on auto-thermal extrusion of ground tire rubber [PDF]

open access: yes, 2019
Ground tire rubber (GTR) was processed using an auto-thermal extrusion as prerequisite to green reclaiming of GTR. The reclaimed GTR underwent a series of tests: thermogravimetric analysis combined with Fourier-transform infrared spectroscopy (TGA-FTIR),

Biocementation Influence on Flexural Strength and Chloride Ingress by Lysinibacillus sphaericus and Bacillus megaterium in Mortar Structures

open access: yesJournal of Chemistry, 2020
The concrete/mortar durability performance depends mainly on the environmental conditions, the microstructures, and its chemistry. Cement structures are subject to deterioration by the ingress of aggressive media.
