Abstract High Pressure Laminates (HPL) panels consist of stacks of self-gluing
paper sheets soaked with phenol-formaldehyde (PF) resins. An important requirement for such PFs is that they must rapidly penetrate and saturate the paper pores.
Partially substituting phenol with bio-based phenolic chemicals like lignin
changes the physico-chemical properties of the resin and affects its ability to
penetrate the paper. In this study, PF formulations containing different proportions
of lignosulfonate and kraft lignin were used to prepare paper-based laminates. The
penetration of a Kraft paper sheet was characterized by a recently introduced, new
device measuring the conductivity between both sides of the… More >

Abstract Biochar amendment is generally recognized as an effective mitigation
option of methane (CH4) emissions from rice cultivation. Although its mitigation
mechanisms are not well understood, the potential relevance of surface area and
porosity of biochar has been discussed. This study aimed to evaluate the application of different biochar particle sizes on CH4 production, oxidation, and emissions from rice cultivation in a clay loam soil, based on the assumption that
porosity and surface area of biochar are directly related to its mitigation effects.
Rice was grown under greenhouse conditions for two growing seasons, either
with 0.5–2 mm (small, SB) or with… More >

Abstract Due to the continuously increasing demand for building materials
across the world, it is necessary to use renewable materials in place of the existing
nonrenewable materials in construction projects. Bamboo is a fast-growing flowering plant that may be used as a renewable material in construction. The use of
bamboo in the construction of buildings can improve its long-term carbon fixation
capacity and economic benefits. Although bamboo has the advantages of superior
performance, low carbon content, high energy-saving and emission-reducing
capacity, bamboo is an anisotropic material, which has many factors affecting
its material performance, large variability of material performance, lack of… More >

Abstract The use of lignin, which is a by-product of the pulp and paper industry, in the
development of asphalt binders would contribute to waste reduction, providing environmental, economic, and social benefits. In this study, samples of lignin-modified asphalt
binder samples with different content of lignin (3%, 6%, 9%, 12%, and 15%) and
unmodified asphalt (control) were tested using Fourier transform infrared spectroscopy (FTIR), dynamic shear rheometer (DSR), and thermogravimetry. The mechanism and effectiveness of lignin in improving the thermal stability of asphalt at
high temperatures were analyzed. The FTIR analysis shows that no new characteristic absorption peak is seen in… More >

Abstract Oil spills and oil/water wastewater are among the great concerns
regarding oil pollution. Existing technologies face many limitations and in some
cases are responsible for causing secondary pollution, therefore there is as seek for
environmental friendly solutions. Biomass, from which celluloses are highlighted,
are being employed for oil/water separation or oil absorbents membranes.
Usually, these membranes are obtained by freeze drying of CNF (cellulose nano-
fibrils) suspensions followed by chemical modification for hydrophobization,
which involves expensive process as chemical vapor deposition and expensive
reactants as sylanes, turning these processes hardly scalable. Here, we produced
a natural porous structure paper from… More >

Abstract Cellulose nanofibrils (CNFs) are promising sustainable materials that
can be applied to nanocomposites, as well as medical and life-sciences devices.
However, methods for the preparation of these important materials are energy
intensive because heating and mechanical disintegration are required to produce
cellulose fibers below 100 nm in size. In this study, CNFs were prepared through
the multi-site regioselective oxidation of cellulose with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and periodate at room temperature (20–25°C), without
any mechanical-disintegration treatment. Transmission electron microscopy
(TEM) revealed that the CNFs had the average widths of 14.1, 55.4, and 81.9
nm for three different treatments. Fourier-transform infrared spectroscopy

Abstract Spent IERs are released during the operation and decommissioning of
nuclear facilities. The safe and efficient treatment of spent IERs is an emergent
problem in nuclear industry. IRN77 is a typical ion exchange resin widely used
in many nuclear power plants. Fenton process can degrade organic resins and
reduce the radioactive residues volume and the disposal cost significantly. In this
work, the IRN77 resin was selected as a model ion exchange resin and its treatment via Fenton process was investigated. The influencing factors for resin degradation, including catalyst dosage, reaction time, initial pH, temperature and
oxidant dosage were investigated and… More >

Abstract Herein, epoxidized soybean oil methyl ester (ESOM) plasticizer was
synthesized for the preparation of plasticized poly(vinyl chloride) (PVC) films
by the alcoholysis and epoxidation. The chemical structure of ESOM was investigated by infrared spectrum and 1H nuclear magnetic resonance. The effect of
content of ESOM and petroleum based plasticizer di-2-ethylhexyl phthalate
(DEHP) on the performance of plasticized PVC films was studied. The result
showed that substituting DEHP with ESOM can improve the thermal stability
of plasticized PVC films. When the weight ratio of ESOM and PVC is fixed at
1:2, plasticized PVC film presents higher elongation at break (350.8% vs.… More >

Abstract This review efficiently covers the research progress in the area of polymer bio composites in perspective of the modern-day renewable materials. In the
last decade, attraction towards the bio-composite based systems has been the topic
of interest due to their potential as a substitute of conventional materials produced
in important manufacturing industries. Recently, preparation of biocompatible and
biodegradable polymer composites is an important achievement as an alternative
of petrochemical based renewable products. Successful production of eco-friendly
bio-composite materials have been achieved with natural fibers viz jute, bamboo,
hair, flex, wool, silk and many others instead of synthesized fibers like carbon,… More >

Abstract Nowadays, the production of consumer goods is based on the use of
non-renewable raw materials, which in recent years has been performing as a problem for the environment. Considering the large number of available biofibers in
nature, their use in the development of polymeric composites has inevitably
emerged, it is also necessary to take into account the countless discarded plastics
that still have the potential to be reused. In this work, fibers were extracted from
pineapple crown residues and utilized to compose sustainable composites using
recycled polypropylene from cups discarded in the trash as a matrix. However,

Abstract A series of hydrogels with different ratios of chitosan and licorice polysaccharide (LP) were prepared by crosslinking to different concentrations of genipin (gp). They were characterized by FTIR (Fourier transform infrared
spectroscopy), SEM (Scanning electron microscope), swelling ratio, rheological
measurements, degradation with time, cytotoxicity, and antibacterial efficacy.
Results show that the hydrogels have porous structures. With an increase in LP
content, the swelling rate grows in the early stage of immersion in buffer and
drops later. The swelling ratio ranged from 986% to 1677%, and stiffness varied
from 777 Pa to 1792 Pa. The addition of LP reduced the mechanical… More >

Abstract Lime-fly ash stabilized loess has a poor early strength, which results in
a later traffic opening time when it is used as road-base materials. Consideration
of the significant early strength characteristics of sulphate aluminum cement
(SAC), it is always added into the lime-fly ash mixtures to improve the early
strength of stabilized loess. However, there is a scarcity of research on the
mechanical behavior of lime-fly ash-SAC stabilized loess and there is a lack of
quantitative evaluation of loess stabilized with binder materials. This research
explored the effects of the amount of binder materials, curing time and porosity
on the… More >
