The term "polyol process" was first used in the late eighties by Fiévet, Lagier, and Figlarz [...].

Introduction And Objective: Conditions resulting from diseases of the brain-gut axis and gum-gut axis show many mutual, often bi-directional interrelationships. The accompanying quantitative and/or qualitative disorders of intestinal microflora may be effectively regulated by implementation of a properly adjusted diet therapy. The aim of the study is to investigate whether there is a relationship between small intestinal bacterial overgrowth (SIBO), and irritable bowel syndrome (IBS), and non-specific inflammatory bowel diseases (IBD), as well as indications for the mode of nutrition.

Human skin plays an important role protecting the body from both extrinsic and intrinsic factors. Skin aging at cellular level, which is a consequence of accumulation of irreparable senescent keratinocytes is associated with chronological aging. However, cell senescence may occur independent of chronological aging and it may be accelerated by various pathological conditions.

Lignin, a renewable and biodegradable polymer, offers a promising alternative to petroleum-based polyols for polyurethane elastomer synthesis. However, its complex structure poses challenges, such as poor dispersibility and reactivity. This study introduces a novel one-step and solvent-free method for synthesizing lignin-containing polyurethane elastomers (SF-LPUes-ONE) with a high lignin substitution rate of at least 30 wt%.

We report a scalable method based on continuous-flow reactors for conformally coating the surfaces of facet-controlled Pd nanocrystals with uniform, ultrathin shells made of Pt. The key to the success of such an approach is the identification of a proper polyol to generate the Pt atoms at a relatively slow rate to ensure adequate surface diffusion and thus the formation of uniform shells in a layer-by-layer fashion. We first demonstrate the concept using the production of Pd@Pt (n = 2-5) core-shell icosahedral nanocrystals and then have the strategy successfully extended to the syntheses of Pd@Pt cubic and octahedral nanocrystals.

Ethylene glycol or one of its oxidation products are believed to serve as reducing agents in the shape-controlled synthesis of Ag nanocubes (NCs) by the polyol process. The identity of end-groups of polyvinylpyrrolidone (PVP) impacts shape control with alcohol and aldehyde moieties serving as a primary Ag reducing agent. We explored the role of PVP end-groups in the polyol process by measuring the dependence of particle number density of Ag NCs produced on the initial concentration(s) of Ag and PVP using small angle x-ray scattering and statistically large particle size distributions analyzed by scanning electron microscopy.
