Development of a radiopaque dental glass for endodontic laser applications

Journal of Materials Research and Technology, 2020
The aim of this study was to develop a laser-sinterable and radiopaque glass powder as a potential sealer in endodontic therapy. The hypothesis was that it is possible to dope a SiO2-Na2O-CaO-P2O5–based glass with barium (Ba) and tantalum (Ta) in such a ...

Inverted Laser Sintering

, 2023
Existing laser sintering systems have several advantages over alternate additive manufacturing technologies but suffer from limitations inherent to the use of a single, self-contained powder bed. This powder bed design limits the ability of the machine to print multiple materials in a single print cycle, obscures the part during printing which can lead

Effect of Powder Bed Fusion Laser Sintering on Dimensional Accuracy and Tensile Properties of Reused Polyamide 11 [PDF]

, 2023
Polyamide 11 (PA11) is a plant-based nylon made from castor beans. Powder bed fusion laser sintering (PBF-LS) is an additive manufacturing process used for PA11 which allows for the reuse of the unsintered powder.

Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

Advanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
