Elution Dynamics of Adsorption: Comparing the Solutions of Direct and Inverse Problems

Image
   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Studies of the elution dynamics of adsorption have revealed a close correspondence between the analytical solutions to (i) a direct problem formulated using an equilibrium adsorption layer model and (ii) an inverse problem formulated using the method of moments. Keywords:  Elution Dynamics; Adsorption; Charcoal; chromatograph; Numerical Equations Introduction The effects of adsorption dynamics on the elution peak profile for an arbitrary adsorption isotherm were previously analyzed in [1] using numerical simulations based on a model that assumed a layer of equilibrium adsorption (LEA model) [2]. Assuming linear adsorption dynamics, [1] revealed that the elution curves simulated using the LEA model agreed well with experimental data obtained for a given integer unit of relative adsorbent bed length (n). The solution parameters to the inverse problem, formulated using the method of moments for integer numbers [3] and e

Polymeric Based Materials via Palladium- Catalyzed Polycondensation

   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract The significant access to the structurally pure, high molar mass, N-containing polymers via palladium-catalyzed polycondensation of various aromatic diamines with various aromatic dibromo compounds is an interesting target. One of the major advantages is to apply inexpensive monomers; aromatic amines and aromatic bromides. Furthermore, many diamines are readily available or easy to synthesize giving fast access to numerous new functionalized polymers either by applying amino-functionalized or bromo-functionalized monomers to optimize and improve the polymer properties. With the increasing demand for different functionalized polymers, the focus of relevant studies has been to generate polymers with improved properties by palladium-catalyzed polycondensation. A series of poly(imino ether)s (PIEs), poly(imino ketone)s (PIKs), poly(imino azobenzene)s (PIAzos), poly(imino acridine)s (PIAcs), poly(imino fluorenone)s (PIFOs

Human-Centric Regulatory in Point-of-Care Manufacturing for 3D Printed PEEK Polymer Implants with Functionalized Implant Surface

                                   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract This article aims to define a regulatory approach for future medical technologies to be applied to the research, design, development, and manufacturing of smart medical devices. In the scope of this perspective: A human-centric regulatory approach and regulatory thinking method for 3D printed PEEK polymer implants. Keywords:  POC solution; polymer; smart implant; regulatory thinking; human-centric regulatory; S.P.E.L.; surface functionalization; additive manufacturing Introduction The healthcare industry is in a transformative change: one of the key enablers of these changes is the proliferation of point-of-care (POC) technologies, which can improve clinical outcomes and reduce costs by increased access. POC technologies have the potential to improve the management and treatment of various diseases and conditions, especially in resource-limited settings, where healthcare infrastructure
