Remarkable solvent tunable aggregation caused quenching for fluorochromic chitosan based hydrogel

Fabrication of Hydrogel with solvent tunable fluorescence property has a novel and significant contribution in current research. Herein, chitosan, functionalized with Fluorescein mono-aldehyde, a light emitting molecule forms a smart strong polymeric gel having nanofibrous architect within micro molecular assembly. Multi functionalities, dynamic and reversible non covalent interactions associated with Fluorescent hydrogel have been portrayed in terms of change in photoluminescence with variation of pH, solvent and temperature in the sol phase. The hydrogel exhibits the distinct photoinduced electron transfer (PET) process within itself. Aggregation caused quenching (ACQ) phenomenon occurs in mixing the suitable pH solutions and Pyridine (similar to 20 fold quenching of fluorescence) and Tetrahydrofuran (similar to 325 fold quenching of fluorescence) with the gel solution. The mechanisms of PET and ACQ process have been well explained with quantitative fluorescence measurement and various kinds of host-guest interactions specially pi-pi interactions and H-bondings. Aggregation of solvent molecules with Fluorescent hydrogel networks has been established by dynamic Light scattering (DLS) study. This aggregation based photoluminescence phenomenon would acquire more response for the extensive usefulness in chemical, biological and material research in future. (C) 2020 Elsevier B.V.

Eco-Friendly Polymer Solar Cells: Advances in Green-Solvent Processing and Material Design

Despite the recent breakthroughs of polymer solar cells (PSCs) exhibiting a power conversion efficiency of over 17%, toxic and hazardous organic solvents such as chloroform and chlorobenzene are still commonly used in their fabrication, which impedes the practical application of PSCs. Thus, the development of eco-friendly processing methods suitable for industrial-scale production is now considered an imperative research focus. This Review provides a roadmap for the design of efficient photoactive materials that are compatible with non-halogenated green solvents (e.g., xylenes, toluene, and tetrahydrofuran). We summarize the recent development of green processing solvents and the processing methods to match with the efficient photoactive materials used in non-fullerene solar cells. We further review progress in the use of more eco-friendly solvents (i.e., water or alcohol) for achieving truly sustainable and ecofriendly PSC fabrication. For example, the concept of water- or alcohol-dispersed nanoparticles made of conjugated materials is introduced. Also, recent important progress and strategies to develop water/alcohol-soluble photoactive materials that completely eliminate the use of conventional toxic solvents are discussed. Finally, we provide our perspectives on the challenges facing the current green processing methods and materials, such as large-area coating techniques and long-term stability. We believe this Review will inform the development of PSCs that are truly clean and renewable energy sources.

Chelating Additives Reversing the Lithium Migration Direction in Ionic Liquid Electrolytes

Binary electrolytes of Li salt in ionic liquid (IL) are interesting systems for battery application. Typical for these systems is a strong Li-anion coordination causing vehicular Li+ transport in negatively charged Li-anion clusters and negative Li+ transference numbers. We investigate the influence of the additives tetrahydrofuran, monoglyme and triglyme on the Li+ migration behavior in 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (EMImTFSA) based mixtures via electrophoretic NMR. When adding coordinating additives, we partly observe a reversal of the lithium migration direction and an electrophoretic drift of the neutral molecule. Using the same O:Li ratio, this effect is strongly depending on the chelating ability of the respective additive. Strongly coordinating additives form a chelate with the Li ion and render its drift velocity and its transference number positive, while the nonchelating additive tetrahydrofuran has a weaker effect on the Li drift. By choice of a suitable additive, it is therefore possible to decompose negatively charged lithium-anion clusters while maintaining ionic liquid-like properties. These findings provide a mechanistic explanation for the beneficial effect of additives on Li+ transport in IL-based battery cells.

Synthesizing isoprene and methyl methacrylate triblock copolymers using peculiar living free radical polymerization with difunctional t-BuLi initiator

A peculiar living free radical polymerization process for the preparation of poly(methyl methacrylate)-b-poly (isoprene)-b-poly(methyl methacrylate) (MIM) triblock copolymers using anionic living polymerization (ALP) combined with mercaptan/epsilon-caprolactam living polymerization (MLP) is developed. Polyisoprene (PI) is first synthesized by ALP using a difunctional t-BuLi initiator with tetrahydrofuran as the polar regulator. Then, a PI with a controlled isomeric unit is end-group functionalized with mercaptans to form an alpha,omega-bismercaptanfunctionalized PI precursor polymer, which is characterized by MALDI-TOF mass spectrometry, after which a thiolamide-structured MIM is formed by MLP at 90 degrees C. Living characteristics are confirmed by GPC, which reveals that MIMs with Mn values of 42.1-81.3 kDa are prepared. The polymers are also characterized by NMR spectroscopy, and gradient polymer elution chromatography. In addition, two Tgs are observed for each polymer by DSC: between-57.2 and 10.4 degrees C, and 99.4 and 119.8 degrees C, which correspond to the separated microphases within each MIM.

Development of Coarse-Grained Models for Poly(4-vinylphenol) and Poly(2-vinylpyridine): Polymer Chemistries with Hydrogen Bonding

In this paper, we identify the modifications needed in a recently developed generic coarse-grained (CG) model that captured directional interactions in polymers to specifically represent two exemplary hydrogen bonding polymer chemistries-poly(4-vinylphenol) and poly(2-vinylpyridine). We use atomistically observed monomer-level structures (e.g., bond, angle and torsion distribution) and chain structures (e.g., end-to-end distance distribution and persistence length) of poly(4-vinylphenol) and poly(2-vinylpyridine) in an explicitly represented good solvent (tetrahydrofuran) to identify the appropriate modifications in the generic CG model in implicit solvent. For both chemistries, the modified CG model is developed based on atomistic simulations of a single 24-mer chain. This modified CG model is then used to simulate longer (36-mer) and shorter (18-mer and 12-mer) chain lengths and compared against the corresponding atomistic simulation results. We find that with one to two simple modifications (e.g., incorporating intra-chain attraction, torsional constraint) to the generic CG model, we are able to reproduce atomistically observed bond, angle and torsion distributions, persistence length, and end-to-end distance distribution for chain lengths ranging from 12 to 36 monomers. We also show that this modified CG model, meant to reproduce atomistic structure, does not reproduce atomistically observed chain relaxation and hydrogen bond dynamics, as expected. Simulations with the modified CG model have significantly faster chain relaxation than atomistic simulations and slower decorrelation of formed hydrogen bonds than in atomistic simulations, with no apparent dependence on chain length.

Optimal Experimental Conditions for Improving the Yield of Poly(limonene) from Photoinduced Polymerization

Limonene represents a possible candidate for the synthesis of polymers from renewable sources. However, because of some structural characteristics, the process yield tends to be considerably low (< 10%). In this sense, the evaluation of still unexplored alternative controlled strategies of synthesis, together with techniques of process optimization, can enable the increase in the polymer yield. Taking this into consideration, this study presents, for the first time, the optimal conditions for maximizing the poly(limonene) yield using a photoinduced polymerization route. The reactions were all conducted at a mild temperature (40 degrees C) and the polymer was characterized by nuclear magnetic resonance (H-1-NMR and C-13-NMR). A face-centered design (FCD) was proposed for interpreting the effects of the reagent ratio (initiator, catalyst, and electron donor amine) on the polymerization. The monomer molar ratio was set to 100 with 6 h of polymerization time. All reagents exerted significant and positive effects on the yield, with the initiator having the most pronounced effect. The optimal conditions for maximizing the yield were as follows: molar ratios of the electron donor amine (PMDETA): 5-8.5; catalyst (TX): 1-1.7; and initiator (TBE): 1.7. Thus, similar to 18% yield could be achieved using a molar ratio of 100:8.5:1.7:1.7 (monomer:PMDETA:TX:TBE). It was observed that the polymer had good adhesion to steel when dried and moderate adhesion to glass. The polymer was insoluble in water and soluble in ethanol, tends to form suspension in solution of ethanol/water, in addition to being partially soluble in tetrahydrofuran and chloroform. These characteristics indicate that the material prepared herein is a promising renewable additive for coatings, films, or adhesives. [GRAPHICS] .

Non-Nucleophilic Electrolyte Based on Ionic Liquid and Magnesium Bis(diisopropyl)amide for Rechargeable Magnesium-Ion Batteries

A non-nucleophilic electrolyte for rechargeable Mg-ion batteries is developed by the reaction of magnesium bis(diisopropyl)amide and 1-ethyl-3-methylimidazolium tetra-chloroaluminate ionic liquid in tetrahydrofuran solvent. The electrolyte shows excellent reversibility and Coulombic efficiency for the Mg deposition/stripping process at room temperature on several working electrodes such as Mo, graphite, and stainless steel. Additionally, the electrolyte shows high anodic stability with Mo as the cathode current collector, with no corrosion detected even after 48 h at 4.5 V versus (Mg/Mg2+). An exceptional cyclability in a full cell configuration using a Chevrel phase Mo 6 S 8 cathode is achieved with a capacity retention of more than 80% for over 300 cycles at a 15 mA g(-1) specific current, making this electrolyte an excellent candidate for rechargeable Mg-ion batteries.

CNC dispersion in PLA and PBAT using two solvents: morphological and rheological properties

Cellulose nanocrystals (CNCs) were dispersed via solution casting in amorphous (A) and semi-crystalline (SC) poly (lactic acid) (PLA) and poly (butylene adipate-co-terephthalate) (PBAT). The protocol, optimized following the Hansen solubility parameter theory, relies on binary mixtures of tetrahydrofuran and dimethyl sulfoxide for the polymers and CNCs, respectively. First highlighted through atomic force microscopy, good filler dispersion and distribution were confirmed by a decrease of the linear viscoelastic region and significant increases of the complex viscosity, storage modulus, and apparent yield stress of the nanocomposites with CNC content, specifically at low frequencies. CNC percolation thresholds of 1, 0.3, and 0.3 wt% were determined in A-PLA, SC-PLA, and PBAT, respectively. These are the lowest to be reported in the literature until now. While PLA retained solvent traces, leading to a significant plasticizing effect, solvent removal was complete in PBAT. It was attributed to the crystallization of PBAT at the drying temperature (70 degrees C).

Microwave-assisted rapid fabrication of robust polyetherimide bead foam parts

Polyetherimide (PEI) is an important candidate for fabrication of high-performance polymer foams. Nevertheless, the manufacture of PEI foamed parts with specific three-dimensional geometry shape and lightweight properties remains a big challenge worldwide. Herein, a microwave (MW)-assisted foaming and selective sintering approach was proposed towards rapid fabrication of robust PEI bead foams. During the process, compressed carbon dioxide/tetrahydrofuran was used as physical co-foaming agent, and the surface-coated graphene nanoplatelets (GNPs) was used as MW absorbent. Upon MW irradiation, the GNPs selectively heated and served as solders that effectively facilitated the foaming of expandable PEI (EPEI) beads, and strongly promoted the local polymer melt and entanglement across the surface of EPEI beads. The MW irradiation power and time were considered as the important parameters to achieve fine inter-bead bonding strength between foamed beads. As a model system, we successfully fabricated a 25-mm-thickness foamed part with an apparent density of 0.32 g/cm(3)and achieved excellent inter-bead bonding performance. Specifically, we also utilized the COMSOL Multiphysics simulations to study the MW selective heating mechanism. This MW-assisted fabrication strategy offers a new foaming approach toward high-performance polymer foamed parts for many advanced applications.

Mainly on the Plane: Deep Subsurface Bacterial Proteins Bind and Alter Clathrate Structure

Gas clathrates are both a resource and a hindrance. They store massive quantities of natural gas but also can clog natural gas pipelines, with disastrous consequences. Eco-friendly technologies for controlling and modulating gas clathrate growth are needed. Type I Antifreeze Proteins (AFPs) from cold-water fish have been shown to bind to gas clathrates via repeating motifs of threonine and alanine. We tested whether proteins encoded in the genomes of bacteria native to natural gas clathrates bind to and alter clathrate morphology. We identified putative clathrate-binding proteins (CBPs) with multiple threonine/alanine motifs in a putative operon (cbp) in metagenomes from natural clathrate deposits. We recombinantly expressed and purified five CbpA proteins, four of which were stable, and experimentally confirmed that CbpAs bound to tetrahydrofuran (THF) clathrate, a low-pressure analogue for structure II gas clathrate. When grown in the presence of CbpAs, the THF clathrate was polycrystalline and platelike instead of forming single, octahedral crystals. Two CbpAs yielded branching clathrate crystals, similar to the effect of Type I AFP, while the other two produced hexagonal crystals parallel to the [1 1 1] plane, suggesting two distinct binding modes. Bacterial CBPs may find future utility in industry, such as maintaining a platelike structure during gas clathrate transportation.
