First-principles insights on mechanical and electronic properties of TiX (X = C, N) in β-Si3N4 based ceramics [PDF]
Processing and Application of Ceramics, 2016 The mechanical and electronic properties of β-Si3N4, TiC-Si3N4 and TiN-Si3N4 ceramics are investigated using density functional theory implemented with GGA/PBE functional. The pristine β-Si3N4 exhibits fracture for a strain of 10%. However, TiC-Si3N4 and

Dielectric properties of calcium-substituted lanthanum ferrite
Journal of Asian Ceramic Societies, 2020 Among La1-xCaxFeO3-δ (0 ≤ x ≤ 0.5) compounds, the optimal value of the direct current conductivity was registered for a 20% substituted amount. We therefore attempted to study the impedance and dielectric properties of 20% calcium-substituted lanthanum ...

Motives with modulus, II: Modulus sheaves with transfers for proper modulus pairs [PDF]
Épijournal de Géométrie Algébrique, 2021 We develop a theory of sheaves and cohomology on the category of proper modulus pairs. This complements [KMSY21], where a theory of sheaves and cohomology on the category of non-proper modulus pairs has been developed.Comment: 31 ...

Deep anterior lamellar keratoplasty in the management of keratoconus
Indian Journal of Ophthalmology, 2013 Advanced cases of keratoconus often require surgical intervention to restore corneal anatomy and improve eyesight. Penetrating keratoplasty (PK) although commonly performed has potential risk of immunological rejection and is now no longer automatically ...

Modulus Stabilization with Bulk Fields [PDF]
, 1999 We propose a mechanism for stabilizing the size of the extra dimension in the Randall-Sundrum scenario. The potential for the modulus field that sets the size of the fifth dimension is generated by a bulk scalar with quartic interactions localized on the

Elastic Properties of Carbon Nanotubes and Nanoropes [PDF]
, 1997 Elastic properties of carbon nanotubes and nanoropes are investigated using an empirical force-constant model. For single and multi-wall nanotubes the elastic moduli are shown to be insensitive to details of the structure such as the helicity, the tube ...

Sensors, 2021 Energy storage and dissipation by composite materials are important design parameters for sensors and other devices. While polymeric materials can reversibly store energy by decreased chain randomness (entropic loss) they fail to be able to dissipate ...

Acidic whey as a novel coupling agent for composites based on E-Glass fibers and low-density polyethylene [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2021 In order to enhance the interfacial-adhesion between short E-glass fibers and low-density polyethylene (LDPE), acidic whey; a dairy byproduct was applied as coupling agent.

Modulus and stiffness of laterally loaded single free headed pile in stratified soil
Journal of Materials and Engineering Structures, 2023 Laterally loaded piles gained its attention when structures like transform towers, offshore structures etc., met huge horizontal loads. Initially, to study the behaviour of laterally loaded piles, homogeneous soil is assumed; whereas in reality the soil ...

The theory and art of corneal cross-linking
Indian Journal of Ophthalmology, 2013 Before the discovery of corneal cross-linking (CXL), patients with keratoconus would have had to undergo corneal transplantation, or wear rigid gas permeable lenses (RGPs) that would temporarily flatten the cone, thereby improving the vision.
