Bonding performance and interfacial adaptation of modern bulk-fill restorative composites after aging in artificial saliva: an in vitro study
This study aimed at comparing the microtensile bond strength (MTBS) and interfacial adaptation of a modern self-curing and a light-curing restorative bulk-fill composite to a conventional composite applied wit...

Open AccessDesign and tribological performance of short S-Glass fibre reinforced biocomposites on the influence of fibre length and concentration
Fibre-reinforced biocomposites usage has gained prominence over the past decade. Although higher fracture toughness was observed when fibres were added to biocomposites, material degradation could occur due to...

Open AccessDimensional stability of short fibre reinforced flowable dental composites
Fibre-reinforced dental composites are proven to have superior mechanical properties in comparison with micro/nano/hybrid filled composites. However, the addition of small quantities of short glass fibres coul...

Open AccessPost-gel polymerisation shrinkage profiling of polymer biomaterials using a chirped fibre Bragg grating
A strain profile measurement technique using a chirped fibre Bragg grating (CFBG) sensor by implementing an integration of differences (IOD) method is reported in this paper. Using the IOD method the spatial d...

Open AccessSelective Atomic-Level Etching on Short S-Glass Fibres to Control Interfacial Properties for Restorative Dental Composites
Interfacial bonding between fibre and matrix is most critical to obtain enhanced mechanical properties of the resulting composites. Here we present a new surface tailoring method of selective wet etching and o...

Open AccessPolymerisation Shrinkage Profiling of Dental Composites using Optical Fibre Sensing and their Correlation with Degree of Conversion and Curing Rate
Traditional polymerisation shrinkage (PS) measurement systems measure average PS of dental composites, but the true local PS varies along the length and breadth of the composite. The PS depends on the curing l...

Titanium-Lead System
The Ti-Pb diagram was investigated in the region 0 to 58 pet Pb and from 500°C to liquidus temperatures. Three reactions were encountered: 1—β→α+Ti4Pb at 725±10°C; 2—β+L→Ti4Pb at 1305±10°C; and 3—the possible eut...
