Abstract We conducted two brittle creep experiments on shale samples under upper crustal conditions (confining pressure of 80 MPa at 26°C and 75°C). deformed the to failure, with bedding oriented perpendicular maximum compressive stress direction, using stress‐stepping methodology. In both experiments, failure was ~64% higher than short‐term peak strength. Throughout each differential step, ultrasonic wave velocities initially decreased then gradually increased deformation/time. The...
Abstract We conducted a series of triaxial creep experiments on shale specimens coming from Tournemire, France, using the stress‐stepping method up to failure, at confining pressure 80 MPa, two orientations (parallel and perpendicular bedding), temperatures 26 75 °C. In these week‐long experiments, stress, strains, P wave ultrasonic velocities were recorded (quasi‐) continuously. The strength failure Tournemire was ~70% higher than peak measured during constant strain rate ( ~10 −7 /s )...
Wireless sensor networks are proved to be effective in long-time localized torrential rain monitoring. However, the existing widely used architecture of wireless for monitoring relies on network transportation and back-end calculation, which causes delay response heavy areas. Our work improves by applying logistic regression support vector machine classification an intelligent node is created Raspberry Pi. The nodes front-end not only obtain data from sensors, but also can analyze...
Due to the water-coning problem, cycle steam stimulation (CSS) in heavy oil reservoirs with bottom water is often less effective, and recovery even below 10%. Steam assisted gravity drainage (SAGD) oil-producing process a constant pressure-drop (about 0.30 MPa), it potential technique for this reservoirs. Through implementation of SAGD, could be effectively controlled. Aiming at block LD5-2N Bohai offshore oilfield, SAGD performance heterogeneous reservoir was numerically studied paper. In...
Abstract Effective anti-infection prophylaxis for chronic wounds can reduce the risk of wound infection and improve healing rates. The use good dressings is particularly important. In this paper, an antimicrobial composite hydrocolloid sponge dressing with zinc oxide nanoparticles, hydroxypropyl chitosan, polyvinyl alcohol as main components was prepared using freeze-drying formulated suspensions. characterizations by scanning electron microscopy, X-ray diffraction, Fourier transform...
Abstract Fractures always play a significant role in tight oil reservoir development. Due to the high conductivity, efficiency of mass transfer between fracture and matrix determines ultimate development effectiveness especially during gas injection process. Convection diffusion have been recognized as two dominant mechanisms affecting transfer. In current studies, many authors illustrate this process by reducing lower-dimensional structure imposing inconsistent boundary conditions on...
Because of its simple principle and high adaptability to severe operational conditions, the capillary-tube viscometer has been widely used for viscosity measurement. However, difficulties in accurately correcting end effect induced measurement deviation will result great uncertainty results. In order solve this problem, work, we studied factors affecting by conducting pressure nitrogen at low flow velocity with an improved viscometer. The experimental results indicated that influence became...
Abstract: As a green and low-energy water treatment technology, solar-driven interface evaporation technology is widely used in seawater desalination, power generation wastewater systems. Here, we developed three-dimensional sponge as solar evaporator by introducing composite hydrophilic polymer (konjac glucomannan, KGM) absorber (reduced graphene oxide, rGO) into the polyvinyl alcohol (PVA) networks, building biomass-derived aerogel cost-effective fashion. Under one sun, achieved rapid rate...
Vernier effect is an effective method to improve the sensitivity of sensor measurement, and a high fiber strain sensing technology based on optical vernier with temperature stability proposed. The basic theory system structure are described in detail, simulated. Theoretical analysis simulation results show that high-sensitivity stable ambient can be realized by cascading two SMS interferometers, increased ten times compared original combining sensitization light transmission characteristics...

The solubility of LiFSI in ET, NPA, IPA, NBA, MAC, EAC, PAC, NBAC, DMC, EMC, DEC at 273.15 K to 313.15 were determined. Elevated temperatures can actuate the continued mixing LIFSI 11 fluids outlined above. In comparison, addition an alkyl group carbon chain a structurally similar solvent molecule will result smaller LiFSI. Overall molar esters are significantly higher than other four alcohols. Besides, corresponding theoretical results mounted by fitting classical equation. deviation fitted...
