Article Abstract
The goal of this study was to examine the effect of thermal cycling on the amount of monomer released from bulk fill composites. Five bulk fill composite resins were used in the study. Extraction solutions were obtained at the end of the time/thermal cycle periods: 0-1 day/0-1,500, 1-3 days/1,500-4,500 and 3-7 days/4,500-10,000. The monomers in the extractions samples taken at each time point were measured on an HPLC instrument. The obtained data were analyzed by repeated measures of variance analysis and tukey multiple comparison tests (p<0.05). The thermocycling increased the amount of monomer released from all composites at 0-1 day (p<0.05). At 0-1 and 1-3 days, Venus Bulk Fill and Filtek Bulk Fill composite resins were more affected. Polymer networks with high molecular weight monomers such as Bis-GMA and UDMA can be less affected by thermal changes compared to polymers with low molecular weight monomers.

Herein, a fluoroalkyl side chain modified A-DA'D-A small molecule acceptor, Y18-F9, was developed to optimize the bulk heterojunction morphology in organic solar cells. The introduction of fluorocarbon chains promotes self-assembly into nanoscale fibrous networks, while the low surface energy drive favorable vertical phase segregation. These synergistic effects lead to enhanced molecular packing, improved charge transport and collection, and reduced recombination losses.

The current most mature, competitive, and dominant battery technology for electric vehicles (EVs) is the Li-ion battery (LIB). As future EVs will rely on battery technology, further innovation is essential for the success of mobility electrification towards improving the driving range and reducing the charging time and price competitiveness. The commonly cited next generation technologies are hybrid and solid-state batteries (SSBs) enabling high energy densities using lithium.

Background: This study investigated the effect of a 45% carbamide peroxide-containing office-type bleaching agent on the microhardness (MH) and surface roughness (SR) of flowable and paste-type bulk-fill composite resins.
Methods: This study used two bulk-fill composite resins, 3 M Filtek Bulk-Fill (paste) and Estelite Bulk-Fill Flow (flowable). Twenty disc-shaped specimens were prepared and divided into two groups according to the type of bulk-fill materials.

Objectives: This in vitro study aims to compare the effect of different light curing modes and curing times on the degree of conversion (DC) and microhardness (MH) of three different bulk fill composites at two different depths.
Materials And Methods: A total of 224 cylindrical specimens (4 mm height, 6 mm diameter) were prepared using four composites: SDR Plus, Ever X Posterior (EXP), Beautifil Bulk Restorative (BBR), and Tetric N Ceram (TNC). Each material group (n = 56) was subdivided into four curing subgroups based on light-curing mode (Low Power or High Power) and exposure time (20-30 s).

Background: Bulk-fill flowable resin composites have demonstrated clinical effectiveness in restoring Class I and II cavities in vital teeth. However, their performance in endodontically treated teeth remains unclear. This randomized, controlled, and double-blind pilot clinical trial aimed to evaluate the one-year clinical performance of direct restorations in endodontically treated premolars, using either a conventional incremental technique or a technique incorporating a bulk-fill flowable composite base.
