Biodegradable and High-performance Poly (butylene adipate-co-terephthalate)-Lignin UV-blocking Films.
Renewable and biodegradable UV-blocking films are in high demand for the increasing need of sustainable environment. Lignin can offer significant UV absorption, but it deteriorates the mechanical properties of films at a high content. In this effort, biobased 10-undecenoic and oleic acids were successfully grafted on soda lignin via solvent- and catalyst-free processes, as confirmed by 31P and 1...

Multiply Wrapped Porphyrin Dyes with a Phenothiazine Donor: A High Efficiency of 11.7% Achieved through a Synergetic Coadsorption and Cosensitization Approach
Photocurrent (Jsc) and photovoltage (Voc) are two important parameters for dye-sensitized solar cells (DSSCs) to achieve high power conversion efficiencies (PCEs). Herein, we synthesize four novel porphyrin dyes, XW36–XW39, using an N-phenyl-substituted phenothiazine donor to pursue higher PCE. For XW36 and XW37, the N-phenyl group is wrapped with two ortho-alkoxy chains. In contrast, it is subst...

Simple Process To Produce High-Yield Cellulose Nanocrystals Using Recyclable Citric/Hydrochloric Acids
Cellulose nanocrystals (CNCs) have great potentials in many applications, such as high-performance nanocomposites. However, there are many challenges in the industrial production of CNCs, such as high cost of acid recovery, acid disposal, low yield, and poor thermal stability. In this study, a simple process to extract CNCs via recyclable acid hydrolysis of microcrystalline cellulose (MCC) is pr...

70. Tandem Chemical Modification/Mechanical Exfoliation of Graphite: Scalable Synthesis of High-Quality, Surface-Functionalized Graphene
Scalable and sustainable preparation of graphene is urgently needed to address its increasing demands in basic research and practical applications. Here, we present a simple preparation of surface-functionalized graphene by ball milling graphite in the presence of an aryl diazonium salt. The efficient exfoliation of graphite is achieved through the tandem surface reaction of graphite with aryl d...

66. Covalent Bonding of Sulfur Nanoparticles to Unzipped Multiwalled Carbon Nanotubes for High-Performance Lithium–Sulfur Batteries
The use of sulfur as a cathode material for lithium-sulfur (Li-S) batteries has attracted significant attention due to its high theoretical specific capacity (1675 mA h g(-1)); however, practicality is hindered by a number of obstacles, including the shuttling effect of polysulfides and the low electrical conductivity of sulfur. Herein, ball milling sulfur with unzipped multiwalled carbon nanotube...

62. Tuning the morphologies of fluorine-doped tin oxides in the three-dimensional architecture of graphene for high-performance lithium-ion batteries
The morphology of electrode materials plays an important role in determining the performance of lithium-ion batteries (LIBs). However, studies on determining the most favorable morphology for high-performance LIBs have rarely been reported. In this study, a series of F-doped SnOx (F-SnO2 and F-SnO) materials with various morphologies was synthesized using ethylenediamine as a structure-directing a...

54. Conjunction of Conducting Polymer Nanostructures with Macroporous Structured Graphene Thin Films for High-Performance Flexible Supercapacitors
Fabrication of hybridized structures is an effective strategy to promote the performances of graphene-based composites for energy,storage/conversion applications. In this work, macroporous structured graphene thin films (MGTFs) are fabricated on various substrates including flexible graphene papers (GPs) through an ice-crystal-induced phase separation process. The MGTFs prepared on GPs (MGTF@GPs) ...

50. Fluorine-Doped SnO2@Graphene Porous Composite for High Capacity Lithium-Ion Batteries
For the first time, a composite of fluorine-doped SnO2 and reduced graphene oxide (F-SnO2@RGO) was synthesized using a cheap F-containing Sn source, Sn(BF4)(2), through a hydrothermal process. X-ray photoelectron spectroscopy and X-ray diffraction results identified that F was doped in the unit cells of the SnO2 nano crystals, instead of only on the surfaces of the nanoparticles. F doping of SnO2 ...
