Covalent organic frameworks (COFs) hold great promise in molecular separation. However, since the aperture size of most COFs is in the range of 0.8–4.9 nm, constructing COF membranes with a smaller aperture size is thus in urgent demand yet remains a grand challenge. In this study, a Brønsted acid mediated…

Facilitate charge transfer at donor/acceptor interface in bulk heterojunction organic photovoltaics by two-dimensional nanoflakes

Yang, Weitao; Ye, Zhixiang; Liang, Tao; Ye, Jian; Chen, Hongzheng

Recently, two-dimensional (2D) materials have been applied in organic photovoltaics (OPVs) as electrode modifier or third component in bulk due to their high charge carrier mobility, various electronic band structure, and facile fabrication via liquid phase exfoliation. Herein, solution exfoliated few layers black phosphorus (BP) and tungsten diselenide (WSe2) were…

Melt-Spun Nanocomposite Fibers Reinforced with Aligned Tunicate Nanocrystals

Redondo, Alexandre; Chatterjee, Sourav; Brodard, Pierre; Korley, LaShanda T. J.; Weder, Christoph; Gunkel, Ilja; Steiner, Ullrich

The fabrication of nanocomposite films and fibers based on cellulose nanocrystals (P-tCNCs) and a thermoplastic polyurethane (PU) elastomer is reported. High-aspect-ratio P-tCNCs were isolated from tunicates using phosphoric acid hydrolysis, which is a process that affords nanocrystals displaying high thermal stability. Nanocomposites were produced by solvent casting (films) or melt-mixing…

Minimizing the energy-level offset between a donor and acceptor in order to reduce energy loss (Eloss) is a hot topic in the field of organic solar cells (OSCs). However, for non-fullerene OSCs, the discussion concerning the relationship between energy-level offset and device performance has not yet reached a general conclusion…

Next-generation high-security cryptography and communication call for nondeterministic generation and efficient authentication of unclonable bit sequences. Physical unclonable functions using inherent randomness in material and device fabrication process have emerged as promising candidates for realizing one-way cryptographic systems that avoid duplication and attacks. However, previous…

Improvement in mechanical and structural properties of poly(ethylene terephthalate) nanohybrid

Saxena, Dipti; Rana, Dipak; Bhoje Gowd, E.; Maiti, Pralay

The wide range of applicability of poly(ethylene terephthalate) (PET) in various fields such as packaging, automobile parts, sports and textile due to its transparent nature, light weight and mechanical properties creates strong case to enhance its mechanical properties. By embedding nanofillers and thereby improving the mechanical properties, this spectrum can…

Comparative Study of Direct Compounding, Coupling Agent-Aided and Initiator-Aided Reactive Extrusion to Prepare Cellulose Nanocrystal/PHBV (CNC/PHBV) Nanocomposite

Zheng, Ting; Clemons, Craig M.; Pilla, Srikanth

Three compounding methods were compared to determine their effects on the organization of the interphase in nanocomposites of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and cellulose nanocrystals (CNCs) processed via (1) direct compounding, (2) reactive extrusion using a coupling agent (PHBV-g-GMA), or (3) reactive extrusion using a peroxide free-radical initiator (dicumyl peroxide,…

Gebhart, Thomas M. J.; Jehnichen, Dieter; Koschichow, Roman; Müller, Michael; Göbel, Michael; Geske, Vinzenz; Stegelmann, Michael; Gude, Maik

The complex mechanical deformation behaviour of closed-cell foams is governed by morphological and physical properties such as cell structure and crystallinity. In this study, the micro-, meso- and macroscopic scale of commercially available bead foam was analysed. Statistical distribution of the cell structure including cell size, wall thickness and shape…

4D biofabrication of skeletal muscle microtissues

Apsite, Indra; Uribe, Juan Manuel; Posada, Andrés Fernando; Rosenfeldt, Sabine; Salehi, Sahar; Ionov, Leonid

Skeletal muscle is one of the most abundant tissues in the body. Although it has a relatively good regeneration capacity, it cannot heal in the case of disease or severe damage. Many current tissue engineering strategies fall short due to the complex structure of skeletal muscle. Biofabrication techniques have emerged…
