Abstract A three reagents adhesive system for wood particleboards not containing any aldehyde was developed by the reaction of glucose or sucrose with triacetin (glycerin triacetate) and with hexamethylene diamine. The system was found
to be based on the mix of three reactions, namely the reaction of (i) glucose with
triacetin, (ii) of the diamine with triacetin, and (iii) of glucose with the diamine.
The chemical species formed were identified by Matrix Assisted Laser Desorption
Ionization Time of Flight (MALDI-ToF) mass spectrometry. Wood particleboard
panels were prepared with this adhesive system and gave good internal bond (IB)
strength results suitable for… More >

Abstract In order to study the effect of recycled plastic particles on the physical
and mechanical properties of concrete, recycled plastic concrete with 0, 3%, 5%
and 7% content (by weight) was designed. The compressive strength, splitting
tensile strength and the change of mass caused by water absorption during curing
were measured. The results show that the strength of concrete is increased by adding recycled plastic into concrete. Among them, the compressive strength and the
splitting tensile strength of concrete is the best when the plastic content is 5%.
With the increase of plastic content, the development speed of early strength… More >

Abstract Increasing usage of foams in various industry sectors had causing serious
disposal problems once it reaches the end of its life-cycle. Herein, PVA-MFC foam
was prepared by freeze-drying using polyvinyl alcohol (PVA) and microfibrillated
cellulose (MFC) as a reinforced material from sugarcane bagasse (SCB). In this
study, the PVA-MFC foam was chemically silylated with Y-methacryloxypropyltrimethoxysilane (MPS) and tetraethoxysilane (TEOS). The wetting ability and
mechanical strength of the silylated 2,20PVA-MFC foam was greatly enhanced compared with unmodified 2,20PVA-MFC foam. The silane chemicals (MPS and TEOS)
had been confirmed grafted on 2,20PVA-MFC foam due to the presence of Si-C and
Si-O-C stretching… More >

Abstract In the current study poly(lactic acid) PLA composites with a 3 wt% and
5 wt% of nanofibrillated cellulose (NFC) were produced by 3D-printing method.
An enzymatic pretreatment coupled with mechanical fibrillation in a twin screw
extruder was used to produce high consistency NFC. Scanning electron microscopy
(SEM) equipped with Fibermetric software, FASEP fiber length distribution analysis, Furrier transform infrared spectroscopy (FT-IR), thermogravimetric analysis
(TGA), tensile tests, impact tests and differential scanning calorimetry were used
to characterize NFC and PLA/NFC composites. The results of the fiber length
and width measurements together with the results of the SEM analysis showed that
enzymatic… More >

Abstract To further verify the feasibility of newly designed reinforced bamboo
scrimber composite (RBSC) beams used in building construction, the bonding
properties between steel bar and bamboo scrimber were investigated by anti-pulling
tests. Results indicated that the anti-pulling mechanical properties were signifi-
cantly correlated to the diameter, thread form and buried depth of steel bar,
forming density of bamboo scrimber as well as the heat treatment of bamboo bundle. There were two failure modes for anti-pulling tests: the tensile fracture and
pulling out of steel bar. Both the ultimate load and average shear strength of
anti-pulling specimen could be increased greatly… More >

Abstract In the production (as co-fuel or alone) of solid refuse fuel (SRF),
knowledge about the characteristics of the raw materials is required for an ecofriendly and effective combustion process. SRFs are commonly produced by drying combustible waste and removing incombustible matter, resulting in a higher
combustibility as compared to the original waste. However, the characteristics
of SRFs may highly vary depending on where and from which materials they
were produced. Thus, we investigated the characteristics of various SRFs using
thermogravimetric analysis (TGA). As a TGA sample is commonly small, on
the scale of milligrams, and, unlike homogeneous fuels, SRFs are… More >

Abstract The aim of this study was to investigate adsorption and desorption characteristics of cadmium ion (Cd(II)) by ash-free biochars and the adsorption
mechanism. Biochars were prepared using peanut shell, bamboo, and Sophora
japonica Linn. Ash-free biochars were obtained by treating the biochars with acid
elution. Adsorption and desorption data from batch experiments were analyzed
using the Langmuir and Freundlich models and three adsorption kinetics models
(i.e., the Pseudo second-order, Elovich model, and the Intraparticle diffusion models). Results showed that the acid elution improved the pore structure of biochars,
increased C content and aromatic functional group content, enhanced biochars
hydrophobicity and… More >

Abstract The adsorption process of new nicotinic derivatives on Fe (110) surface
and diffusion of corrosive particles in inhibition film were studied by quantum
chemistry and molecular dynamics simulation, and inhibition mechanism of
inhibitor was discussed. The results indicated that the main active sites of three
inhibitors are located in N atoms on the five membered ring. The inhibitor
YM-1 has the strongest activity of electrophilic reaction, and the adsorption process of inhibitor molecules is polycentric chemisorption. The adsorption energy
for inhibitors followed the order of YM-1 > YM-2 > YM-3. The adsorption film
YM-1 more effectively impedes the diffusion and… More >

Abstract The present paper deals with the effect of loading different pineapple
leaf fibre (PALF) length (short, mixed and long fibres) and their reinforcement
for the fabrication of vinyl ester (VE) composites. Performance of PALF/VE composites was investigated through three-point bending flexural testing and viscoelastic (dynamic) mechanical properties through dynamic mechanical analysis
(DMA). DMA results revealed that the long PALF/VE composites displayed better mechanical, damping factor and dynamic properties as compared to the short
and mixed PALF/VE composites. The flexural strength and modulus of long
PALF/VE composites were 113.5 MPa and 14.3 GPa, respectively. The storage
(E′) and loss (E″) moduli… More >
