Hace 1 día · The most used additive techniques are stereolithography (SLA), selective laser sintering (SLS), and fused deposition modeling (FDM) (Gaal et al., 2017). In SLA, a power source, such as UV, is used to cure photocurable resins layer by layer, while in SLS technology, a laser is used to combine small pieces of a material powder into an object with the required 3D structure.
Hace 1 día · Fused quartz is notoriously tough to work with, but our team’s skill and our state-of-the-art five-axis vertical machining center made the impossible possible. Over four days of intensive work, we meticulously carved and shaped the quartz, overcoming its inherent challenges to produce a flawless representation of the iconic monument.
Hace 3 días · Generalized fused Lasso (GFL) is a powerful method based on adjacent relationships or the network structure of data. It is used in a number of research areas, including clustering, discrete smoothing, and spatio-temporal analysis. When applying GFL, the specific optimization method used is an important issue. In generalized linear models, efficient algorithms based on the coordinate descent ...
Hace 1 día · All-polymer solar cells (all-PSCs) have been achieved tremendous focus recently due to their superior mechanical robustness and excellent thermal stabilities. However, there are few instance on the application of a small molecule acceptor (SMA) to all-PSCs. Herein, a highly crystalline non-fused ring (NFR) S
Hace 1 día · Refractory materials based on sintered and fused calcium zirconate were used for the lining of the boiler and the coal gasifying chamber [11, 30]. The material based on sintered CaZrO 3 showed better resistance to the impact of coal ash than products based on electrocast calcium zirconate [ 31 ].
Hace 4 días · A series of thiopyran-fused polycyclic aromatic hydrocarbons (PAHs) have been straightforwardly synthesized from 2,5-di(1-en-3-ynyl)thiophene-containing precursors via one-pot ring-expansion and 6-endo cyclization reactions. The reaction monitoring and the density function theoretical calculation suggest that the ring-expansion reaction occurs prior to 6-endo cyclization. Moreover, the ...
Hace 3 días · May 25, 2024. Fused glass art by Brenda Butterfield, Rehoboth Art League guest instructor. SUBMITTED PHOTO. The Rehoboth Art League will offer a fused glass workshop for beginners from 10 a.m. to 12 p.m., Thursday, May 30, at 12 Dodds Lane, Henlopen Acres. Students will learn basic fusing concepts focusing on arranging glass for flat fusing.
