Silane and silazane surface modification of recycled glass fibers for polypropylene composites

Journal of Applied Polymer Science, Volume 140, Issue 5, February 5, 2023., 2023
This study investigates the efficiency of multifunctional silane and silazane agents for surface modification of recycled glass fibers. Overall, the amino‐silane reagents improve the dispersion of GFs in PP, and permit subsequent reaction with MAPP leading to better compatibilization, with moderate improvements in strength attributed to the ...

Screw-Dislocation-Driven Growth of Two-Dimensional Few-Layer and Pyramid-Like WSe2 by Sulfur-Assisted Chemical Vapor Deposition [PDF]

ACS Nano 2014, 2014
Two-dimensional (2D) layered tungsten diselenides (WSe2) material has recently drawn a lot of attention due to its unique optoelectronic properties and ambipolar transport behavior. However, direct chemical vapor deposition (CVD) synthesis of 2D WSe2 is not as straightforward as other 2D materials due to the low reactivity between reactants in WSe2 ...

Should we use cortical bone screws for cortical bone trajectory?

Journal of Neurosurgery : Spine, 2015
OBJECT In 2009, Santoni et al. reported cortical bone trajectory (CBT) as a method of inserting pedicle screws to obtain more solid fixation, and proposed the use of cortical trajectory screws with a more closely placed thread (cortical screws) for CBT ...

Enabling Augmented Segmentation and Registration in Ultrasound-Guided Spinal Surgery via Realistic Ultrasound Synthesis from Diagnostic CT Volume [PDF]

arXiv, 2023
This paper aims to tackle the issues on unavailable or insufficient clinical US data and meaningful annotation to enable bone segmentation and registration for US-guided spinal surgery. While the US is not a standard paradigm for spinal surgery, the scarcity of intra-operative clinical US data is an insurmountable bottleneck in training a neural ...

A new concept for implant fixation: bone-to-bone biologic fixation [PDF]

European Cells & Materials, 2015
Many attempts have been made to reduce complications of bone implant, such as pedicle screw loosening. To address this problem, the authors suggest a new concept of bone-to-bone biologic fixation using recombinant human bone morphogenetic protein-2 ...

Fermented lingonberry juice's effects on active MMP‐8 (aMMP‐8), bleeding on probing (BOP), and visible plaque index (VPI) in dental implants—A clinical pilot mouthwash study

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1322-1330, December 2022., 2022
Abstract Objectives We aimed to study the effects of fermented lingonberry juice (FLJ) as a mouthwash on the levels of active matrix metalloproteinase‐8 (aMMP‐8) in peri‐implant sulcular fluid (PISF), bleeding on probing (BOP), and visible plaque index (VPI). We hypothesized that FLJ rinsing could reduce inflammation (aMMP‐8 and BOP) and microbial load
