Extrinsic n‑Doping of a Double B←N Bridged Bipyridine-Based Polymer Containing Oligoethylene Glycol Side Chains

In a paper published in Polymer Science & Technology, an international team of scientists
has, for the first time, introduced oligoethylene glycol side chains into A-A type polymers containing BNBP units, designing a polar side chain-functionalized organic boron polymer, PBN-OEG. The introduction of polar ethylene glycol side chains improves the miscibility between the host material and small molecule dopants, exhibiting a more efficient n-type small molecule doping level compared to the control material PBN-alkyl, which only contains alkyl side chains. Consequently, PBN-OEG possesses superior thermoelectric properties, with an optimal electrical conductivity of up to 1.95 S cm-1 and a maximum power factor of up to 4.7 μW m-1 K-2. Furthermore, the oligoethylene glycol side chains promote the swelling of PBN-OEG films in aqueous electrolyte solutions, facilitating the ionic transport of hydrated cations. Therefore, PBN-OEG can be used as a channel material for organic field-effect transistors (OECTs), achieving a large volumetric capacitance (C*) of 97.7 F cm-3 and a high figure of merit (μC*) of 2.6 F cm-1 V-1 s-1. This study demonstrates the potential of n-type BNBP-based OMIEC materials in the fields of organic thermoelectric transistors (OTEs) and OECTs. This study is led by Jian Liu (Key Laboratory of Polymer Science and Technology, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022, China) and Jun Liu (Key Laboratory of Polymer Science and Technology, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022, China).

Simultaneous knockout of multiple eukaryotic translation initiation factor 4E genes confers durable and broad-spectrum resistance to potyviruses in to***co

In a paper published on aBIOTECH, the authors identified resistance-breaking Potato virus Y (PVY RB) isolates and emerging potyviruses (TVBMV and ChiVMV) in Yunnan to***co fields, and revealed that combined inactivation of eIFiso4E-T in the va (lacking eIF4E1-S) genetic background confers durable resistance to PVY, while knockout of eIFiso4E-S in the va genetic background confers resistance to TVBMV and ChiVMV; pyramiding mutations in these genes achieved broad-spectrum potyvirus resistance without compromising plant growth, offering a novel strategy for engineering resistance crops.

Emerging strategies to improve heat stress tolerance in crops

Heat stress has become one of the major threats to agricultural production. With the sharp increase in future food demand, breeding heat-tolerant crop varieties has become an urgent task for ensuring food security. In a recent review article published in aBIOTECH, Xiong et al. summarizes the latest research on the impact of heat stress (HS) on major cereal crops at various developmental stages. The review highlights the use of beneficial natural variants and gene-editing techniques to improve crop tolerance to heat stress, emphasizing the value of alleles associated with thermomemory, combined stress tolerance, and the balance between stress responses and growth.

Toughening Vitrimers Based on Dioxaborolane Metathesis through Introducing a Reversible Secondary Interaction

In a paper published in Polymer Science & Technology, an international team of scientists
explores an effective protocol for toughening vitrimers based on dioxaborolane metathesis through introducing a reversible secondary interaction and revealed the underlying molecular mechanism of this protocol. They copolymerized hexyl methacrylate with hydrogen-bonding n-isopropyl methacrylamide and vitrimeric cross-linkers to prepare dual-cross-linked networks. They found the breakup of the hydrogen bonds during the elongation significantly dissipated the energy, leading to the softening of the materials, thereby facilitating the stretch to high strain. Then the Dobrynin model modified by Konkolewicz and co-workers upon including a strain rate-dependent element was used to capture the softening process. The deviation at a high content of hydrogen bonds was attributed to the coupled motion of the hydrogen bonds where the distance between hydrogen bonds becomes smaller than the Kuhn length. Modification of the model according to this change is considered an interesting future work. This study is led by Shilong Wu and Quan Chen (State Key Laboratory of Polymer Physics and Chemistry, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022, China).

Robust, Thermally Stable and Impurity-Tolerant Aluminum-Based Catalyst System for Polylactide Production under Industrial Conditions

In a paper published in Polymer Science & Technology, an international team of scientists
designed and synthesized tetracoordinate aluminum methyl complexes bearing (amidoalkyl)pyridine−phenolate (AmPyPh) pincers for industrial L-LA polymerizations. Then they further investigated the electronic and steric effects of the substituents in different positions on catalytic activity with assistance of density functional theory calculation. The results indicated the synthesized AmPyPh-Al catalysts exhibited excellent thermostability as well as good protonic tolerance, which could effectively promote the polymerization of technical grade L-LA without further purification under industrial-relevant conditions (150−180 °C, in melt and bulk) with catalyst concentrations as low as 0.0005 mol % (monomer/catalyst feed ratio = 200000:1). Meanwhile, these novel Al complexes could suppress the epimerization side reaction under harsh conditions and afforded semicrystalline PLLA. This study is led by Xiaosa Zhang (College of Science, Shenyang University of Chemical Technology, Shenyang 110142, China) and Bin Wang (Tianjin Key Laboratory of Composite & Functional Materials, School of Materials Science and Engineering, Tianjin University, Tianjin 300350, China).
