Synthesis of figure-of-eight helical bisBODIPY macrocycles and their chiroptical properties
A macrocyclic bisBODIPY (bis(boron-dipyrromethene)) complex [1B2] with a figure-of-eight helicity was synthesized and successfully resolved. [1B2] was proven to be one of the most efficient red-emitting CPL (circularly polarized luminescence) fluorophores reported to date (λ = 663 nm, |glum| = 9 × 10(-3), ΦF = 0.58).
Using Commercial Enzymes to Produce Cellulose Nanofibers from Soybean Straw
This study used commercial enzymes to isolate cellulose nanofibrils (CN) and produce sugars from chemically pretreated soybean straw (SS) (stem, leaves, and pods) by alkali (NaOH 5 or 17.5% v/v at 90°C for 1 h or at 30°C for 15 h) and bleaching (NaClO 2 3.3% or H 2 O 2 4%) pretreatments. Depending on the pretreatment…
A strategy to achieve enhanced electromagnetic interference shielding at low concentration with a new generation of conductive carbon black in a chlorinated polyethylene elastomeric matrix
The fabrication of scalable and affordable conductive Ketjen carbon black (K-CB)-elastomer composites for adjustable electromagnetic interference (EMI) shielding remains a difficult challenge. Herein, chlorinated polyethylene (CPE)-K-CB composites have been developed by single step solution mixing to achieve high EMI…

A LiMn2O4-Polypyrrole System for the Extraction of LiCl from Natural Brine
A highly selective LiMn 2 O 4 -Polypyrrole electrochemical cell for the extraction of LiCl from natural brine is described. Reproducible intercalation of Li + in Li x Mn 2 O 4 (0 ≤ x ≤ 1) and Cl − in oxidized polypyrrole (PPy + ) is achieved with an overall cell voltage of less 1 V over more than 200 cycles with 50% c…
Ultra-small lipid–polymer hybrid nanoparticles for tumor-penetrating drug delivery
Lipid-polymer hybrid nanoparticles, consisting of a polymeric core coated by a layer of lipids, are a class of highly scalable, biodegradable nanocarriers that have shown great promise in drug delivery applications. Here, we demonstrate the facile synthesis of ultra-small, sub-25 nm lipid-polymer hybrid nanoparticles…
Effects of heteroatom substitution in spiro-bifluorene hole transport materials
-methoxy substituent on bulk properties, such as the photophysical properties, HOMO/LUMO energy level, hole extraction properties and morphologies of perovskite thin films are investigated. Their optoelectronic and charge-transport properties and performance in perovskite solar cells are compared with the current benc…
Novel properties and potential applications of functional ligand-modified polyoxotitanate cages
Functional ligand-modified polyoxotitanate (L-POT) cages of the general type [TixOy(OR)z(L)m] (OR = alkoxide, L = functional ligand) can be regarded as molecular fragments of surface-sensitized solid-state TiO2, and are of value as models for studying the interfacial charge and energy transfer between the bound functi…
