Abstract Background The black soldier fly ( Hermetia illucens ) is gaining attention as an efficient decomposer of food waste. However, recalcitrant compounds such plastics mixed into waste may have negative effects on its growth and survival. Moreover, efficiency degradation also be affected by plastics. In addition, salt (NaCl) can present in high concentrations, which reduces the H . -mediated treatment. this study, we assessed larvae (BSFL) reared containing polyethylene (PE) polystyrene...

Abstract BACKGROUND Rice straw is an attractive lignocellulosic material for ethanol production, since it one of the most abundant renewable resources. It generally has high cellulose and hemicellulose contents that can be readily hydrolysed into sugars subsequent fermentation. The pretreatment method plays important role in increasing efficiency enzymatic saccharification, thereby making whole process economically viable. Torrefaction appropriate technique enhancing reaction production ....

Barley straw (Hordeum vulgare L.) is an attractive lignocellulosic material and one of the most abundant renewable resources for fuel ethanol production. Although it has high cellulose hemicellulose contents, there are several challenges limitations in process converting to ethanol. High ash, silica lignin contents barley make inferior feedstock enzymatic hydrolysis. Therefore pretreatment could play important role inducing structural compositional changes that increase efficiency hydrolysis...

Abstract The rhamnolipid biosurfactant‐producing bacterium, strain SDRB ‐G7, was isolated from the sediment of Sindu‐ri beach and identified as Rhodococcus fascians based on a phylogenetic analysis. Optimal activity, with highest yield (2.441 g/L) surface tension‐reducing activity (24.38 mN /m), observed when cells were grown olive oil their sole source carbon at pH 8.0. biosurfactant showed environmental stability variety NaCl concentrations (2‐20%) values (2‐12) even under acidic...

The effects of torrefaction the biopellets made from hardwood chip residue (HW), camellia oilseed cake (CO), and pruning remnants toothache tree (TA) mulberry (MT) were evaluated. Torrefaction reduced volatile matter content by 18–58% increased their heating value without negatively impacting durability or fines content. also initial ignition time 50–59% prolonged combustion duration 15–24%. Regardless type feedstock, all exhibited mass yields in range 60–80% energy ranging 80–95%. novelty...

A developing method of cancer detection is to use electromagnetic waves compare the dielectric properties normal and cancerous tissue. Because most previous studies consisted measurements taken ex-vivo, this study investigated advantages in-vivo measurements, obtained using newly developed insertion-type planar probe, through (MDA MB 231), which was cultivated implanted into mammary fat pad nude mice. Reflection coefficients were in broadband frequency range from 0.5 30 GHz, complex...

Microparticulates are an effective three-dimensional (3D) matrix for the culture of stem cells to be used in tissue engineering bone. Herein, bioactive calcium phosphate microparticles with evacuated morphology were prepared, and their potential support bone was addressed. Spherical particles sizes hundreds micrometers produced using emulsification method, during which internal portion aid solvent evaporation. The microspheres, is considered enhance cell population replaced new bone, found...

In this study, we investigated the applicability of wood powder to manufacture paperboard. Laboratory studies and mill trials were carried out develop suitable for a functional additive paperboard determine its ability improve sheet bulk reduce drying steam. The was manufactured by grinding screening. maximum particle size critical factor affecting as an additive. laboratory studies, handsheets containing made, their physical strength properties analyzed. increased decreased sheets....

In a previous study the authors determined that non-woody materials including brewers’ grain (BG) and oil palm frond (OPF) could be alternatives to wood powder as organic fillers. However, they have disadvantage of deteriorating strength paperboard. If paperboard improved, then one would expect more production cost reductions bulk improvements by increasing addition this study, surface modification fillers was used method improve strength. The goal find most effective condition for...

Blown films having a broad range of morphologies were prepared from high-density polyethylenes (HDPE) with unimodal and bimodal molecular weight distribution under several processing conditions, the effect their morphological features on dart drop impact resistance, Elmendorf tear strength, tensile properties has been studied. The organization lamellar stacks seems to play critical role mechanical blown HDPE films. resistance is highly dependent presence network structure level...

The applicability of oil palm biomass, EFB(Empty Fruit Bunch) as raw materials for environmental friendly packaging material, pulp mold, was evaluated in this study. changes the water absorption properties mold by addition EFB and surface treatments with PVA AKD were analyzed measuring rate contact angle. each sample prepared using laboratory wet molder. And samples times a 0.1 ml drop on surface. to made OCC resulted decrease increase showed significant reduction rate. However, case ONP no...

Many studies have reported that cellulose nanofibrils (CNFs) show high potential for use in many industries, but this material has been considered too costly commercialization. An effective treatment is therefore needed to reduce the production costs of CNFs. This study describes electron beam irradiation as a new pretreatment manufacture CNFs and effectiveness refining process, which part CNF production. Bleached kraft pulps were irradiated by an subsequently refined, followed measurement...

London Convention on the prevention of marine pollution by dumping wastes and other matter prohibits deliberate disposal paper mill sludges at sea. In order to explore alternative plan prohibition sludge sea, biodegradable seedling pot was developed mixing with old newspaper (ONP) in appropriate ratios. The C/N ratio mixed below 20, leading rapid deterioration organic matters composing pot. increased ONP contents resulted increase thickness thereafter decrease density. Cellulose fibers...

Abstract We investigated the miscibility windows in blends of poly(vinyl chloride) (PVC) with chemically modified styrene/acrylonitrile (SAN) copolymers such as α‐methyl (α SAN), styrene/methacrylonitrile (MSMAN). The PVC α SAN were found to have broader window. This enhanced was interpreted terms intramolecular repulsion that originates from unfavorable interaction between counits and also association AN units. interactions studied by using Fourier transform infrared (FT‐IR) spectroscopy....
