Recycle Glass

open access: yesChallenging Glass Conference Proceedings
Increasing the circularity of flat glass does not only mean to collect glass cullet from internal and pre- consumer processes. It also means to use glass cullet from the post- consumer applications, such as residential or commercial buildings.

Anal Gland/Duct Cyst: A Case Report [PDF]

open access: yesAnnals of Coloproctology, 2020
Anal gland/duct cyst (AGC) is rare and observed in only 0.05% of patients undergoing anal surgery. AGC is thought to be a retention cyst in the anal gland and arises when an obstruction of the anal duct causes fluid collection in the anal gland.

Effective thermal strengthening of glass by enhanced configurational entropy at its supercooled state

open access: yesMaterials & Design
Glass is a representative of fragile material. But it can be used as a good protective cover when strengthened. As a method of such strengthening, so-called “physical tempering” is widely used for large glass plates.
