Permeability and conductivity of platelet-reinforced membranes and composites [PDF]
, 2001 We present large scale simulations of the diffusion constant $D$ of a random composite consisting of aligned platelets with aspect ratio $a/b>>1$ in a matrix (with diffusion constant $D_0$) and find that $D/D_0 = 1/(1+ c_1 x + c_2 x^2)$, where $x= a v_f/b$ and $v_f$ is the platelet volume fraction.

Modeling of Polymer Clay Nanocomposite for a Multiscale Approach [PDF]
, 2008 The mechanical property enhancement of polymer reinforced with nano-thin clay platelets (of high aspect ratio) is associated with a high polymer-filler interfacial area per unit volume. The ideal case of fully separated (exfoliated) platelets is generally difficult to achieve in practice: a typical nanocomposite also contains multilayer stacks of ...

A Wigner-Seitz model of charged lamellar colloidal dispersions [PDF]
Phys. Rev. E 56, 3137 (1997)., 1997 A concentrated suspension of lamellar colloidal particles (e. g. clay) is modelled by considering a single, uniformly charged, finite platelet confined with co- and counterions to a Wigner-Seitz (WS) cell. The system is treated within Poisson-Boltzmann theory, with appropriate boundary conditions on the surface of the WS cell, supposed to account for ...

Transmission matrix of a uniaxial optically active crystal platelet [PDF]
, 2005 Expressions corresponding to the transmission of a uniaxial optically active crystal platelet are provided for an optical axis parallel and perpendicular to the plane of interface. The optical activity is taken into account by a consistent multipolar expansion of the crystal medium response due to the path of an electromagnetic wave. Numerical examples

Therapeutic potential of adult platelets and cord blood platelets in future clinical directions
Journal of Medical and Scientific Research, 2023 Platelet rich plasma (PRP) is currently obtaining a natural concentration of autologous growth factors, and is used in different medical conditions. This review is aimed to establish several treatment options using adult PRP and scope of the therapeutic ...

Platelets, 2023 Kappa-carrageenan (KCG), which is used to induce thrombosis in laboratory animals for antithrombotic drug screening, can trigger platelet aggregation. However, the cell-surface receptor and related signaling pathways remain unclear.

Platelets, 2022 MYH9-related disorder (MYH9-RD) is autosomal dominant thrombocytopenia caused by mutations in the MYH9 gene, which codes for the non-muscle myosin-IIA heavy chain. We present a case of a 24-year-old Chinese man with MYH9-RD who was initially misdiagnosed

Differential expression of exosomal microRNAs in fresh and senescent apheresis platelet concentrates
Platelets, 2022 Patients have a high risk of suffering adverse reactions after receiving platelet products stored for 5 days. Bioactive exosomes in platelet products can be accumulated during storage, which is associated with adverse reactions.

Platelets, 2022 While several small studies have found that selenium deficiency is associated with low platelet counts, they lack generalizability. We used data from the National Health and Nutrition Examination Surveys collected over a 12-year period.

Platelets, 2022 The risk of bleeding as predicted by the PRECISE-DAPT score can vary over time after percutaneous coronary intervention (PCI). We sought to compare the predictive ability of the PRECISE-DAPT score calculated at baseline and reassessed during follow-up in
