The vapor pressures and the aqueous solubilities of 411 compounds with a large structural diversity were investigated using quantitative structure−property relationship (QSPR) approach. A five-descriptor equation squared correlation coefficient (R2) 0.949 for pressure six-descriptor R2 0.879 solubility obtained. All descriptors derived solely from chemical structure compounds. QSPR equations allow reliable prediction water−air partition coefficients.
A comparative study of metal-free air-operated polypyrrole and PEDOT based trilayer actuators is presented. Actuators made both pure combined conducting polymers are considered. Trilayer bending actuators, synthesized in similar conditions, characterized terms the structure, electrochemical electro-chemo-mechanical properties. The characterization was carried out using two popular electrolytes: LiTFSI propylene carbonate a room-temperature ionic liquid EMIm TFSI. results reveal that...
Abstract A large-scale effort was carried out to test the performance of seven types ionic electroactive polymer (IEAP) actuators in space-hazardous environmental factors laboratory conditions. The results substantiate that IEAP materials are tolerant long-term freezing and vacuum environments as well ionizing Gamma-, X-ray UV radiation at levels corresponding low Earth orbit (LEO) main aim this material behaviour investigation is understand predict device service time for prolonged exposure...
An investigation of cell-penetrating peptides (CPPs) by using combination Artificial Neural Networks (ANN) and Principle Component Analysis (PCA) revealed that the penetration capability (penetrating/non-penetrating) 101 examined can be predicted with accuracy 80%-100%. The inputs ANN are main characteristics classifying penetration. These molecular (descriptors) were calculated for each peptide they provide bio-chemical insights criteria Deeper analysis PCA results also showed clear...
Abstract Living materials are created through the embedding of live, whole cells into a matrix that can house and sustain viability encapsulated cells. Through immobilization these cells, their bioactivity be harnessed for applications such as bioreactors production high‐value chemicals. While interest in living is growing, many existing lack robust structure difficult to pattern. Furthermore, employ only one type microorganism, or microbial consortia with little control over arrangement...
Additive manufacturing allows three-dimensional printing of polymeric materials together with cells, creating living for applications in biomedical research and biotechnology. However, an understanding the cellular phenotype within is lacking, which a key limitation their wider application. Herein, we present approach to characterize materials. We immobilized budding yeast Saccharomyces cerevisiae three different photo-cross-linkable triblock hydrogels containing F127-bis-urethane...
Cancer cells have unique but widely varying characteristics that proven them difficult to be treated by classical therapeutics and calls for novel selective treatment options. Nanomaterials (NMs) been shown display biological effects as a function of their chemical composition, the extent exact nature these can vary between different environments. Here, ZnO NMs are doped with increasing levels Fe, which allows finely tune dissolution rate resulting in significant differences behavior on...
While metal oxide nanoparticles (NPs) are one of the most commonly used nanomaterials, theoretical models to analyze and predict their behavior have been mostly based on just chemical composition or extrapolation from small clusters' calculations. In this study, a set novel, full-particle descriptors for modeling, grouping read-across NP properties biological activity was developed force-field calculation potential energies whole NPs. The capability these nanodescriptors group nanomaterials...
Toxicity and cancer-killing potency of Fe-doped ZnO nanoparticles can be reliably modelled using atomistic nanodescriptors.
The immobilization of dodecylbenzenesulfonate (DBS<sup>−</sup>) in polypyrrole (PPy) during electropolymerization is typically expected to lead cation-driven activity. Here we demonstrate that the actuation direction changed by using same electrolyte but different solvent.
Either as salts or room temperature ionic liquids, fluorinated anion-based electrolytes have been a common choice for electroactive polymer actuators, both linear and bending. In the present work, propylene carbonate solutions of four three hugely popular anions-triflouromethanesulfonate, bis(trifluoromethane)sulfonimide, hexafluorophosphate were compared evaluated in polypyrrole actuators. The actuation direction, characteristics-performance relations influence behavior Isotonic...
Wider availability of marine proteins for development food and biomedical applications has high importance. Sea cucumber body wall have specific functional properties which could be very promising such product development. However, protein extraction from whole animals is costly complex, whereas peptide hydrogel production by biotechnological methods can considered an economically viable approach. Body-wall derived peptides sea Parastichopus tremulus been suggested as a nontraditional source...

Several EU initiatives and directives emphasize waste reduction immediate reuse at the source. This study introduces a novel on-site recycling method for transforming printing house paper into high-quality, eco-friendly cardboard without mixing it with lower-quality or heterogeneous streams. Instead of traditional water- energy-intensive processes, proposed dry defibration involves mechanical grinding, spray-on binder application, heat pressing, significantly reducing ecological footprint....
