Local structure of amorphous and crystalline Ge2Sb2Te5 films

Physics of Complex Systems, 2021
An effective way to examine structural rearrangement in solids is Mössbauer spectroscopy. A key requirement to Mössbauer probes used for these purposes is the possibility of their localization in a certain site of the crystal lattice or in the structural

Use of Dichlorodimethylsilane to Produce Polydimethylsiloxane as a Substitute for Vitreous Humour: Characteristics and In Vitro Toxicity

Journal of Functional Biomaterials, 2023
Polydimethylsiloxane (PDMS) is a substitute for vitreous humour in vitreoretinal surgery and is usually produced from octamethylcyclotetrasiloxane (D4). In Indonesia, both commercial PDMS and D4 are limited and expensive.

Vitreous Substitutes as Drug Release Systems

Translational Vision Science & Technology, 2022
Vitreous substitutes are traditionally used to stabilize the retina after vitrectomy. In recent years, various approaches have been developed for using the vitreous substitute not only as a tamponade but also as a drug release system to tackle ocular diseases.

Two-step versus 1-step subretinal injection to compare subretinal drug delivery: a randomised study protocol

BMJ Open, 2021
Introduction There is increasing interest in subretinal injections as a surgical procedure, largely as a result of emerging treatments for ocular diseases which necessitate this manoeuvre.

Injectable hyaluronic acid-collagen derived hydrogel based on component biomimetic as vitreous substitute

Materials & Design
Vitrectomy is a common clinical treatment for fundus disease. Due to the non-renewable nature of the vitreous, artificial vitreous are usually required to replace natural vitreous to perform functions post operation.

Vitreous Substitutes: Old and New Materials in Vitreoretinal Surgery

Journal of Ophthalmology, 2017
Recent developments in vitreoretinal surgery have increased the need for suitable vitreous substitutes. A successful substitute should maintain all the physical and biochemical properties of the original vitreous, be easy to manipulate, and be long ...

Effect of temperature and glass content on crystalline phases in porcelain sintered with recovered automotive glass

Heliyon, 2023
In the pursuit of sustainable porcelain production, this research examines the potential of using recovered automotive glass as a substitute for traditional feldspar, specifically feldspar imported from Spain. Porcelain samples were sintered at different

Mechanical Models of the Dynamics of Vitreous Substitutes [PDF]

BioMed Research International, 2014
We discuss some aspects of the fluid dynamics of vitreous substitutes in the vitreous chamber, focussing on the flow induced by rotations of the eye bulb. We use simple, yet not trivial, theoretical models to highlight mechanical concepts that are relevant to understand the dynamics of vitreous substitutes and also to identify ideal properties for ...

Exploring Sangelose-cyclodextrin in situ-forming hydrogels for vitreous substitution: design, development, and characterization

Materials & Design
This study aimed to develop an in situ-forming hydrogel based on Sangelose® (SG) and cyclodextrins (CDs) as a vitreous substitute for intravitreal injection following vitrectomy.
