The role of fast and slow processes in the formation of structure and properties of thermoplastic polyurethanes

Anokhin, D. V.; Gorbunova, M. A.; Estrin, Ya I.; Komratova, V. V.; Badamshina, E. R.

New multi-blocked thermoplastic polymers containing rigid polyurethane-urea and soft polydiethylene glycol adipate blocks have been synthesized. Basic features of their structure formation have been revealed. Three types of supramolecular organization have been found, which define the behavior of samples under heating and deformation conditions. The shape memory effect has been…

We report the synthesis and comparative study of five conjugated polymers P1–P5 with different arrangements of two solubilizing 2-ethylhexyl side chains in their repeating units. It has been shown that positioning of the alkyl substituents affects strongly frontier energy levels of the polymers and results in variation of their optical…

Acid Induced Self-Assembly Strategy to Synthesize Ordered Mesoporous Carbons from Biomass

Xu, Fan; Chen, Yiqing; Tang, Minghui; Wang, Haiyan; Deng, Jiang; Wang, Yong

Hydrothermal carbonization of biomass is an economic and sustainable technique for the fabrication of functional carbonaceous materials. However, the introduction of biomass into synthesis of ordered mesoporous carbon materials achieves slow progress due to complicated requirements. It is still challenging to prepare biomass-derived ordered mesoporous carbon materials. Herein, we report…

Nonconventional biomacromolecular luminogens have attracted extensive interest due to their fundamental importance and potential applications in diverse areas. To explore novel luminogens and, moreover, to gain deeper insights into their emission mechanism, we study the emission behaviors of sodium alginate (SA), a natural anionic polysaccharide composed of mannuronic (M) and…

It is promising, yet challenging, to employ molecules of slight synthetic complexity to construct efficient and low-cost organic solar cells (OSCs). Herein, two unfused acceptors, DF-TCIC and HF-TCIC, were developed for OSC applications, in which the 3,4-difluorothiophene core connected through a cyclopentadithiophene (CPDT) bridge to 1,1-dicyanomethylene-3-indanone derivatives (IC for DF-TCIC…

Improving the film quality is of great importance in promoting the power conversion efficiency (PCE) of 2D perovskite-based solar cells (PVSCs), but the solution to this issue is limited. In this work, a strategy of combining the advantages of the ammonium thiocyanate (NH4SCN) additive and merged annealing (MA) process was…

Reactive oxygen species (ROS)-responsive nanomedicine for RNAi-based cancer therapy

Li, Yang; Bai, Hongzhen; Wang, Hebin; Shen, Youqing; Tang, Guping; Ping, Yuan

Although much effort has been dedicated to the development of efficient siRNA delivery for cancer therapy, delivery nanomaterials that can particularly respond to reactive oxygen species (ROS), which are overproduced in the tissue and mitochondria of cancer cells, are still rare for the clinical translation of RNA interference (RNAi)-based therapy.…

High-Efficiency Construction of CO2-Based Healable Thermoplastic Elastomers via a Tandem Synthetic Strategy

Yang, Guan-Wen; Wu, Guang-Peng

The alternating copolymerization of CO2/epoxides to polycarbonates (CO2–PCs) has been an area of research focus because of the growing concern about energy and the environment. Regardless of the enormous progress that has been made, the lack of functionalities and inert chemical structure of CO2-based polycarbonates greatly limit the scope of…

Epsilon-Fe2O3 Nanocrystals inside Mesoporous Silicas with Tailored Morphologies of Rod, Platelet and Donut

Li, Jheng-Guang; Fornasieri, Giulia; Bleuzen, Anne; Gich, Martí; Impéror‐Clerc, Marianne

The ϵ-Fe2O3 polymorph of iron oxide, which has outstanding physical properties, is successfully stabilized inside mesoporous silica particles with tailored shapes. Using mesoporous silica particles with three different morphologies of rod, platelet and donut, we obtain ϵ-Fe2O3/mesoporous silica nanocomposites. Iron oxide is loaded inside the porosity using a two steps…
