Streszczenie:

We propose a chemical language processing model to predict polymers’ glass transition temperature (Tg) through a polymer language (SMILES, Simplified Molecular Input Line Entry System) embedding and recurrent neural network. This model only receives the SMILES strings of a polymer’s repeat units as inputs and considers the SMILES strings as sequential data at the character level. Using this method, there is no need to calculate any additional molecular descriptors or fingerprints of polymers, and thereby, being very computationally efficient. More importantly, it avoids the difficulties to gen

Conducting Polymers (CPs) represent a unique class of materials that combine the electrical conductivity of metals with the mechanical properties and processability of conventional polymers. This paper provides a comprehensive review of the various types of conducting polymers, including Polyaniline (PANI), Polypyrrole (PPy), Polythiophene (PT), and their derivatives. The synthesis techniques of these polymers, such as Chemical, Electrochemical, and Template-Based Methods, are discussed, highlighting their impact on the polymer's structure, conductivity, and functional properties.

We present a simple mean-field theory to describe the polymer-mediated depletion attraction between colloidal particles that accounts for the polymer’s chain stiffness. We find that for fixed polymer radius of gyration and volume fraction, the strength of this attraction increases with increasing chain stiffness in both dilute and semidilute concentration regimes. In contrast, the range of attraction monotonically decreases with chain stiffness in the dilute regime, while it attains a maximum in the semidilute regime. The obtained analytical expressions for the depletion interaction were compa

Many desirable characteristics of polymers arise from the method of polymerization and structural features of their repeat units, which typically are responsible for the polymer’s performance at the cost of processability. While linear alternatives are popular, polymers composed of cyclic repeat units across their backbones have generally been shown to exhibit higher optical transparency, lower water absorption, and higher glass transition temperatures. These specifically include polymers built with either substituted alicyclic structures or aromatic rings, or both. In this review article, we

The general claim about novel molecularly imprinted polymers is that they are selective for their template or for another target compound. This claim is usually proved by some kind of experiment, in which a performance parameter of the imprinted polymer is shown to be better towards its template than towards interferents. A closer look at such experiments shows, however, that different experiments may differ substantially in what they tell about the same imprinted polymer’s selectivity.

The chapter deals with brief introduction to polymers, composites, and nanocomposites along with their reliability. When we talk about polymeric composites, the terms crystallinity and amorphicity play a very important role, and both of these properties are highly affected by variation in temperature condition. On increasing temperature, the crystalline domains of polymers tend to become amorphous, and as we reduce the temperature, crystalline domains tend to increase. So the reliability of a particular polymer is widely dependent on temperature conditions.

Abstract Organic polymers have found wide spread use as inhibitors for the prevention of mineral scales in heat transfer equipment. Recently a biodegradable organic polymer has been developed which provides both scale and corrosion control. The development of the polymeric inhibitor and laboratory evaluations of scale and corrosion inhibition is discussed together with its potential application in open recirculating cooling systems.

A series of platinum catalytic systems stabilized in aromatic polymers were obtained in this work. Commercially available styrene-divinylbenzene (MN100) and polymers synthesized by one-stage crosslinking by the Friedel-Crafts reaction from benzene, naphthalene, and an equimolar benzene-naphthalene mixture were used as polymers. The obtained systems were tested in liquid-phase hydrogenation reactions of benzene, toluene, and benzene-toluene mixture, as well as anthracene in a dodecane medium. The reaction products were studied using GC-MS. Polymers and catalytic systems were studied using diffu

Interaction of high photon energy (> 5-eV) radiation from excimer lasers with polymeric materials has drawn much interest because of its potential importance in material processing such as etching and patterning which have found use over a number of diversified fields such as medicine, polymer science, and microelectronics. The laser etching process is noncontact, maskless, selective, and offers a high spatial resolution. Although the topic has been the subject of numerous recent studies, basic parameters for understanding interactions between polymers and high energy photons are not well u

Polymer flooding is one of the most promising EOR methods (Smalley et al. 2018). It is well known and has been used successfully (Pye 1964; Standnes & Skjevrak 2014; Sheng et al. 2015). From a technical perspective we recommend that polymer flooding should be considered as a viable EOR method on the Norwegian Continental Shelf for the following reasons: 1. More oil can be produced with less water injected; this is particularly important for the NCS which are currently producing more water than oil 2. Polymers will increase the aerial sweep and improve the ultimate recovery, provided a prop

In the Cesar Department in Colombia, sustainable agriculture faces critical challenges despite its thriving livestock sector. Extensive cattle ranching and poor soil management worsen soil conditions. Additionally, significant environmental concerns arise from the substantial discharge of wastewater in the dairy processing industry. This study aims to valorize biosolids derived from wastewater during dairy plant disinfection to enhance sustainable livestock production. It explores the use of biosolids as the primary matrix for creating composted compounds and biopolymers for agricultural purpo
