Experimental Section: Precursor preparation TiO2 mesoscopic film was prepared by doctor-blading of commercially available anatase paste (Dyesol, 18NR-T) on cleaned FTO glass, then slowly heated up to 450°C and kept for 30 min to form the porous mesoscopic film. After, there are three steps for the quaternary precursor to be insitu deposited and coated onto the mesoscopic TiO2 film: 1. 100 mL 0....

Inspired by a case study, this paper reports a successful application of VNS to the production planning and scheduling problem that arises in the glass container industry. This is a multi-facility production system, where each facility has a set of furnaces where the glass paste is produced in order to meet the demand, being afterwards distributed to a set of parallel molding machines. Since th...

We present industrialized bifacial solar cells on large area (149 cm) 2 cm CZ monocrystalline silicon wafers processed with industrially relevant techniques such as liquid source BBr3 and POCl3 open-tube furnace diffusions, plasma enhanced chemical vapor deposition (PECVD) SiNx deposition, and screen printed contacts. The fundamental analysis of the paste using at boron-diffused surface and the...

PDMS-based films with 14 wt% carbon black were formed with varying amounts of hexane (Sigma-Aldrich) to determine the effect of the solvent on electrical resistance. Five formulations were prepared with hexane at 0, 100, 150, 200, and 300% by weight, relative to the pre-polymer. Without hexane, the suspension was a thick paste that had to be applied by doctor blading; with hexane, the suspensio...

A solid freeform fabrication technique, freeze extrusion fabrication (FEF), was investigated for the creation of three-dimensional bioactive glass (13-93) scaffolds with pre-designed porosity and pore architecture. An aqueous mixture of bioactive glass particles and polymeric additives with a paste-like consistency was extruded through a narrow nozzle, and deposited layer-by-layer in a cold env...

Alkali-activated materials have the potential to replace Portland cement in certain applications. To better understand these binders’ properties, it is relevant study their rheological behaviour at early ages, like case of paste. There are already many studies on available literature, using fly ash, metakaolin, and ground granulated blast furnace slag as precursors. However, this discusses beha...

STATEMENT OF THE PROBLEM Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) increases the mineral content of tooth structure. This may enhance the chemical bonding of glass ionomer cements (GIC) and marginal sealing of their restorations. PURPOSE The aim of this study was to evaluate the effect of CPP-ACP paste pretreatment on the microleakage of three types of GIC. MATERIALS AND M...

Hollow glass microspheres (HGMS) have been widely used in the hydrocarbon industry for cementing wells with low-density slurries. These consist of amorphous siliceous hollow spheres filled gas, providing a material high compressive strength. The present study aims to characterize interaction between HGMS and cement paste, focusing mainly on development pozzolanic activity, given nature silica. ...
