Geothermal formations often contain extensive fracture networks. These networks contribute to the significant loss of drilling fluids during geothermal drilling. Multiple circulation materials (LCM) such as fiber, granules, and pills have been proposed tackle this problem but with only limited success. Recent advances in science led development thermoset shape memory polymers (SMP) address lost...

OBJECTIVES This study aimed to compare the durability of four adhesive systems by assessing their microtensile bond strength (MTBS) and microleakage during six months of water storage. MATERIALS AND METHODS A total of 128 human third molars were used. The adhesives tested were Scotch Bond Multipurpose (SBMP), Single Bond (SB), Clearfil-SE bond (CSEB), and All-Bond SE (ABSE). After sample prep...

INTRODUCTION Root canal sealers used in odontological applications are capable of providing an apical seal, thus inhibiting potential bacterial penetration into the periradicular tissues. Since insolubility is the ideal characteristic for a root canal sealer material, in dentistry the sealability of the material depends on its solubility. PURPOSE This study tested the solubility of six differ...

Graphite foil (GF) compressed from exfoliated graphite (EG) is a sealing material, which used in nuclear energy and the chemical industry. The preparation of complex process, includes intercalation graphite, water washing, thermal exfoliation pressing intermediate products. conditions significantly influence structure material its physicochemical properties. Thus, aim work was to reveal correla...

With the growing emphasis on minimization of global plastic waste, flexible fibre-based packaging has gained significant interest over past few years. Heat-sealing technology is commonly applied for vertical form-fill-seal machine to provide tight closure packages maintaining food quality and shelf life. Several different seal bar geometries adequate heat-seal parameters are required improve ti...
