Surface modification of cellulose nanocrystals (CNC) by organocatalysed grafting from ring-opening polymerization (ROP) of trimethylene carbonate was investigated. Organocatalysts including an amidine (DBU), a guanidine (TBD), an amino-pyridine (DMAP) and a phosphazene (BEMP) were successfully assessed for this purpose, with performances in the ord...

Background Nowadays, a wide range of wound dressings is already commercially available. The selection of the dressing is of paramount importance as inappropriate wound management and dressing selection can delay the wound healing process. Not only can this be distressing for the patient, but it can also contribute to complications such as maceratio...
Hole transporting materials (HTMs) with high charge carrier mobilities and receptive functionalities have gained significant attention recently due to their direct effect on boosting the efficiency and lifetime of perovskite solar cells (PVSCs). Herein, two new simple small molecular diketopyrrolopyrrole-based HTMs with different central pi-bridges...
Non-fullerene acceptors (NFAs) are excellent light harvesters, yet the origin of their high optical extinction is not well understood. In this work, we investigate the absorption strength of NFAs by building a database of time-dependent density functional theory (TDDFT) calculations of ∼500 π-conjugated molecules. The calculations are first validat...

A great deal of attention has been paid in recent years to the integration of two and three-dimensional integrated electronic parts into plastics, both for their potential applications in modern human lives and for their outstanding properties, which include the ability to reduce product weight and space while increasing product reliability. The de...
Environmental stability remains a major challenge for the commercialisation of organic solar cells and degradation pathways remain poorly understood. Designing materials for improved device stability requires an understanding of the relationship between the properties of the donor or acceptor molecule and different degradation mechanisms. Here we s...
Flow of complex fluids in porous structures is pertinent in many biological and industrial processes. For these applications, elastic turbulence, a viscoelastic instability occurring at low Re—arising from a non-trivial coupling of fluid rheology and flow geometry—is a common and relevant effect because of significant over-proportional increase in ...
На основе развития рыночных отношений в РФ многие проектные организации стали бороться за улучшение качества и прочности дорожной одежды, задумываться о том, как эффективно уменьшить цену на строительство и реконструкцию дорог, сохранив их на высоком уровне. На помощь строительству пришли технологии геосинтетических материалов, обеспечивающие повыш...
Design and preparation of mixed-matrix membranes (MMMs) with minimum defects and high performance for desired gas separations is still challenging as it depends on a variety of MMM synthesis parameters. In this study, 6FDA-DAM:DABA based MMMs using MOF-808 as filler were prepared to examine the impact of multiple variables on the preparation proces...
