Cellulose-based materials are vulnerable to moisture and microorganisms thus lose their original mechanical properties durability; meanwhile, self-cleaning technique as a disruptive nanotechnology of waterproofing is attracting tremendous interest. Here, we develop facile, cheap, scalable "top-down" strategy fabricate transparent surface for cellulose-based by spray-coating stable emulsion nano-SiO2 particles. The nanoparticles precisely synthesized at an average diameter ∼110 nm via sol–gel...
To further improve the preparation efficiency and properties of bamboo fiber reinforced polymer composites (BFRPs) fabricated by vacuum-assisted resin transfer molding (VARTM) process. Here, fiber/glass mesh hybrid (BGRPs) were VARTM to determine effects three stacking sequences (namely, GBBGBBG, BGBGBGB, BBGGGBB; B: fiber, G: glass mesh) on physical mechanical properties, as well void characteristics BGRPs (i.e. BGRP-1, BGRP-2, BGRP-3). The results showed that incorporation meshes could...
Accurate characterization of fluid phase behavior is an important aspect CO2 enhanced shale oil recovery. So far, however, there has been little discussion about the nanopore confinement effect, including adsorption and capillarity on equilibrium water-oil-CO2 mixtures. In this study, improved three-phase flash algorithm proposed for calculating water-oil-gas mixture basis extended Young-Laplace equation a newly developed fugacity calculation model. The model can consider effect equilibrium....
Abstract Shale gas reservoirs have been successfully developed due to the advancement of horizontal well drilling and multistage hydraulic fracturing techniques. However, optimization design drilling, fracturing, operational schedule is a challenging problem. An ensemble-based method (EnOpt) proposed here optimize hydraulically fractured in shale reservoir. The objective maximize net present value (NPV) which requires simulation model predict cumulative production. To accurately describe...
The investigation of elemental sulfur solubility plays critical roles on sour gas reservoir development. In this paper, the was directly measured by static method with samples from well M1 a in Sichuan Basin. results show that ranges 0.001 g/cm 3 to 0.968 at 40–98.9 MPa and 15–49.8 MPa. increases increasing temperature pressure, especially when pressure is greater than 30 Moreover, H 2 S content mixtures also an important factor affecting solubility. mixtures. experimental data paper display...
An approach involving low energy consumption was used to transform jute/polypropylene prepregs into a sustainable sandwich structure for automotive application. Fiber orientation and stacking sequence were modified investigate their influence on the physical-mechanical properties of as well cyclic flexural properties, compression fatigue behaviors 3D microstructure honeycomb panels. The mechanical face sheets comparable with GF-SMC; but since they are derived from natural fiber present more...
This study focuses on three different regions of moso bamboo (Phyllostachys edulis): an inner layer (IB), middle (MB), and outer (OB), to comprehensively characterize the structural features, chemical composition (ash, extractives lignin contents), monomeric as determined by analytical pyrolysis. The results show that presents a gradient structure. From IB OB, vascular bundle density fiber sheath ratio increase, porosity decreases (from 45.92% 18.14%), diameter-chord increases 0.85 1.48). In...
Sulfur deposition commonly occurs during the development of a high-sulfur gas reservoirs. Due to high flow velocity near wellbore, some deposited sulfur particles re-enter pores and continue migrate driven by high-speed flow. The current mathematical model for ignores viscosity between particles, rising caused turbulence, corresponding research on release ratio particles. In order solve above problems, firstly, viscous force turbulence disturbance are introduced, critical is derived. Then,...
Bamboo can be processed into engineering materials with excellent properties by reasonable processing methods. In this study, the performance of mould-pressed bamboo (MBP) veneer products was examined. The physical mechanical and connection MPB were tested, application analyzed. results show that has a comprehensive property high internal bonding good dimensional stability, its density are similar to those wood stock. overall bending strength, modulus, compression strength 29.0 MPa, 6.83...
This study aimed to evaluate the tensile properties and failure mechanisms of bamboo slivers that were subjected different methods laser-cutting with changing parameters. The sample was observed through in situ testing combined scanning electron microscopy. results indicated could achieve high efficiency minimal size variation machining; however, calculated needed modification.

Chitin nanocrystal (ChiNC), a kind of rod-like nanoparticle, exhibits high elastic modulus, mechanical strength, good biocompatibility, and biodegradability. Its aqueous dispersion behaves with prominent shear thinning concentration-related sol-gel transition characteristics, which has feasibility extrusion-based 3D printing, that is, direct ink writing (DIW). Based on this, herein, ChiNC was chosen as matrix material to explore its printability via DIW. A waterborne polycitrate prepolymer...
The presence of water, i.e., connate or hydraulic fracturing along with the gaseous hydrocarbons in shale nanopores is largely overlooked by previous studies. In this work, a new unified real gas-transport model has been developed for both organic and inorganic porous media accounting nanoconfined water film flow. More specifically, gas core flows center organic/inorganic pore surrounded which can be further divided into an interfacial region (near-wall water) bulk (bulk water). We...
In pressure sensitive reservoirs, interaction effects among the porous media flow field, fracture field and stress can cause some specific characteristics entirely different from those in conventional reservoirs. Dynamic behavior is one of them, which generates a change value aperture even variation anisotropy permeability. this paper, we focus on dynamic fractures affecting factors, including driving in-situ stress. Numerical discrete network (DFN) models are built solved by finite element...
