Castellanos-Soriano, Jorge;Alvarez-Gutierrez, Daniel;Jimenez, M. Consuelo;Perez-Ruiz, Raul research published 《 Photoredox catalysis powered by triplet fusion upconversion: arylation of heteroarenes》, the research content is summarized as follows. In this work, the feasibility of triplet fusion upconversion (TFU, also named triplet-triplet annihilation upconversion) technol. for the functionalization (arylation) of furans and thiophenes has been successfully proven. Activation of aryl halides by TFU leads to generation of aryl radical intermediates; trapping of the latter by the corresponding heteroarenes, which act as nucleophiles, affords the final coupling products. Advantages of this photoredox catalytic method include the use of very mild conditions (visible light, standard conditions), employment of com. available reactants and low-loading metal-free photocatalysts, absence of any sacrificial agent (additive) in the medium and short irradiation times. The involvement of the high energetic delayed fluorescence in the reaction mechanism has been evidenced by quenching studies, whereas the two-photon nature of this photoredox arylation of furans and thiophenes has been manifested by the dependence on the energy source power. Finally, the scaling-up conditions have been gratifyingly afforded by a continuous-flow device.

Cassin, Savannah R.;Flynn, Sean;Chambon, Pierre;Rannard, Steve P. research published 《 Accessing new and scalable high molecular weight branched copolymer structures using transfer-dominated branching radical telomerization (TBRT)》, the research content is summarized as follows. Academic and com. branched polymer synthesis very commonly relies upon a repeating chem. derived from a single monomer. Literature reports of branched homopolymers often rely upon chemistries that are difficult to scale. Step-growth polymerizations are widely utilized which also limit the mol. weight of resulting branched macromols. The recent reports of transfer-dominated branching radical telomerization (TBRT) provide readily accessible routes to a range of previously inaccessible macromol. architectures utilizing free radical reactions but resulting in step-growth-like backbones. Here we show how TBRT may be used to form branched statistical copolymers with step-growth backbone chemistries using facile free radical reaction conditions through three novel synthesis strategies leading to new materials with readily tunable phys. properties. The strategies are outlined conceptually, exemplified by exptl. examples and determination of glass transition temperatures provides clear evidence of homogeneous statistical copolymer formation.

MXene/polymer composites have gained widespread attention due to their high elec. conductivity and extensive applications, including electromagnetic interference (EMI) shielding, energy storage, and catalysis. However, due to the difficulty of dispersing MXenes in common polymers, the fabrication of MXene/polymer composites with high elec. conductivity and satisfactory EMI shielding properties is challenging, especially at low MXene loadings. Here, we report the fabrication of MXene-armored polymer particles using dispersion polymerization in Pickering emulsions and demonstrate that these composite powders can be used as feedstocks for MXene/polymer composite films with excellent EMI shielding performance. Ti₃C₂T_z nanosheets are used as the representative MXene, and three different monomers are used to prepare the armored particles. The presence of nanosheets on the particle surface was confirmed by XPS and SEM. Hot pressing the armored particles above T_g of the polymer produced Ti₃C₂T_z/polymer composite films; the films are elec. conductive because of the network of nanosheets templated by the particle feedstocks. For example, the particle-templated Ti₃C₂T_z/polystyrene film had an elec. conductivity of 0.011 S/cm with 1.2 wt % of Ti₃C₂T_z, which resulted in a high radio frequency heating rate of 13-15°C/s in the range of 135-150 MHz and an EMI shielding effectiveness of ~21 dB within the X band. This work provides a new approach to fabricate MXene/polymer composite films with a templated elec. network at low MXene loadings.

Butnaru, Elena;Brebu, Mihai research published 《 The Thermochemical Conversion of Forestry Residues from Silver Fir (Abies alba Mill.) by Torrefaction and Pyrolysis》, the research content is summarized as follows. Forestry residue is a renewable energy biomass whose valorization has increased due to the interest in replacing exhaustible and environmentally unfriendly fossil resources. Needles, cones and bark from silver fir were thermally processed by separated and combined torrefaction (250°C) and pyrolysis (550°C). The torrefaction removed the humidity and extractives and degraded the hemicelluloses, significantly decreasing the oxygen content to ∼11 wt% and increasing the carbon content to ∼80 wt%, while enhancing the calorific value of the solids (∼32 MJ/kg). The pyrolysis produced solid materials with high amounts of fixed carbon (∼60-70 wt%) and high heating values, of ∼29 MJ/kg. The combined torrefaction + pyrolysis increased the energy yield of the process and decreased the O/C and H/C at. ratios to about 0.1 and 0.5, resp., which is close to those of coals. It also led to condensable products with more homogeneously distributed compounds, regardless of the initial biomass type. More than 110 chem. compounds were confirmed in the condensable products, in amounts that depended on the type of starting material and on the thermal treatment. These included the following: terpenes, from extractives; furans, acids and linear ketones, from hemicelluloses; cyclic ketones and saccharides, from cellulose; and aromatic hydrocarbons and phenol derivatives, from lignin. Clear distinctions between the thermal procedures and the sample origins were evidenced by an exploratory data anal. (PCA), which suggested the presence of different types of lignin in the three starting materials.
