The ability to control glass surface reactivity at different length enables key properties required for future “smart substrates”. Employing a thermal poling process on a specific borosilicate glass composition can yield a surface with tailored physical and chemical properties. This work shows that during poling, alkali contained in the glass matrix migrates from the anode to the cathode side o...

This work presents a comparative analysis of top gate a-IGZO TFTs fabricated on both soda-lime-silica glass and alkali-free borosilicate glass. Low-temperature ALD is selected for the deposition of gate dielectric to minimize a thermal stress. Comparing with TFTs on alkali-free borosilicate glass, TFTs with soda-lime-glass show similar threshold voltage and subthreshold swing, but slightly degr...

background: glass and quartz fiber posts are used in restoration of structurally compromised roots. accessory fiber posts are recently introduced to enhance the fiber post adaptation. this study evaluated the effectiveness of glass versus quartz accessory fiber posts. materials and methods: in this experimental study, 40 mandibular premolar roots with similar dimension (radius of 3.5 ± 0.2 mm a...

the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...

The plate of a pultruded fiber-reinforced polymer or fiber-reinforced plastic (FRP) profile produced via a pultrusion process is likely to undergo local buckling and cracking along the fiber direction under an external load. In this study, we constructed a pultruded glass-fiber-reinforced polymer-light wood composite (PGWC) profile to explore its mechanical performance. A rectangular cross-sect...

statement of problem: fracture strength of a denture base resin is of great concern, and many approaches have been used to strengthen acrylic resin dentures. purpose: the aim of this study was to measure the transverse strength of a heat polymerized acrylic resin, after reinforcement with metal wire and two types of glass fibers. materials and methods: forty rectangular specimens (65.0×10.0×3.3...

The use of high-quality thermal insulation materials to improve the energy efficiency buildings is strongly increasing. Foam glass, a durable and porous material that resistant almost all substance effects, one best materials. Glass foaming complicated process affected by types agents used in initial composition mixture mode foaming. influence components - glass matrix agent discussed this pape...

We report the first ever photon correlation spectroscopy performed on single alkali and mixed alkali metaphosphate glasses at refractory temperatures above the glass transition. We find not only a significant decrease in the glass transition temperature but also a decrease in fragility for the mixed alkali composition as compared with the single akali glasses. We argue that structural relaxatio...

the idea of combining low weight and good mechanical properties has led to efforts to develop a new light fiber/metal laminate (fml) in the last decade. fmls are hybrid composites consisting of alternating thin layers of metal sheets and fiber-reinforced epoxy prepregs. in this study, the effect of fiber orientation on tensile properties of this material is investigated both analytically and ex...
