The generation of spherical colloids titania with uniform diameters (see Figure for an SEM image) has been achieved using a new precursor. By varying the concentration titanium glycolate in acetone diameter these could be controlled 200–500 nm range. as‐synthesized also readily assembled into 3D crystalline lattices qualities sufficiently good optical characterization.
A facile, environmentally benign approach has been developed for the preparation of dynamic, multiresponsive, and self-healing hydrogels from inexpensive bamboo pulp, poly(vinyl alcohol) (PVA), borax. The microfibrillated cellulose (MFC) reinforced PVA–borax were produced through a one-pot route in conjunction with ball milling physical blending tandem aqueous medium. In this way, MFC particles could be efficiently generated well-dispersed polymer matrix, they have verified by scanning...
Exploring functional substrates and precisely regulating the electronic structures of atomic metal active species with moderate spin state are great importance yet remain challenging. Hereon, we provide an axial Fe-O-Ti ligand regulated spin-state transition strategy to improve oxygen reduction reaction (ORR) activity Fe centers. Theoretical calculations indicate that ligands in FeN3 O-O-Ti can induce a low-to-medium optimize O2 adsorption by O. As proof-of-concept, oriented catalyst was...
High efficiency organic solar cells (OSCs) based on A-DA'D-A type small molecule acceptors (SMAs) were mostly fabricated by toxic halogenated solvent processing, and power conversion (PCE) of the non-halogenated processed OSCs is mainly restricted excessive aggregation SMAs. To address this issue, we developed two vinyl π-spacer linking-site isomerized giant (GMAs) with linking inner carbon (EV-i) or out (EV-o) benzene end group SMA longer alkyl side chains (ECOD) for capability...
Power conversion efficiency (PCE) of organic solar cells (OSCs) processed by nonhalogenated solvents is unsatisfactory due to the unfavorable morphology.
