Increasing evidence shows that mechanical stresses are critical in regulating cell functions, fate, and diseases. However, no methods exist can quantify isotropic compressive stresses. Here we describe fluorescent nanoparticle-labeled, monodisperse elastic microspheres made of Arg-Gly-Asp-conjugated alginate hydrogels (elastic round microgels, ERMGs). We generate 3D displacements calculate strains tractions exerted on an ERMG. Average ERMG 570 Pa within layers 360 tumor-repopulating (TRC)...
To study the crashworthiness of single- and multi-cell, square structures under axial loads, response surface models these were established separately by using polynomial method (PRSM). The describe surfaces specific energy absorption (SEA), peak crushing force Fmax mean Favg variation side-length a, wall thickness t number cells N in structure. results showed that for thin-walled with same N, SEA basically increases decreases a; while but remained unchanged a. Besides, dimensional...
Ni-based superalloy with ceramic thermal barrier coatings (TBCs) is a composite material, which can be used in special environments high temperature and pressure such as aeroengine blade. In order to improve the cooling effect of aeroengine, it necessary perform multi-size large-area holes processing on surface blades. As non-contact method fast speed, good quality almost no deformation, laser has been one important methods for film hole Percussion drilling presented using picosecond...
Abstract Irregular honeycomb structures occur abundantly in nature and man-made products, are an active area of research. In this paper, according to the optimization regular structures, two types irregular with both positive negative Poisson’s ratios presented. The elastic properties honeycombs varying structure angles were investigated through a combination material mechanics structural methods, which axial deformation rods was considered. numerical results show that has significant...
High-altitude environments are characterized by low air pressures and temperature variations. Low-heat Portland cement (PLH) is a more energy-efficient alternative to ordinary (OPC); however, the hydration properties of PLH at high altitudes have not been previously investigated. Therefore, in this study, mechanical strengths levels drying shrinkage mortars under standard, low-air-pressure (LP), variable-temperature (LPT) conditions were evaluated compared. In addition, characteristics, pore...
Thermal barrier coatings (TBCs) is one of the main key technology for high-pressure turbine blades which are components high-performance aerospace engines. It offers protection underline metallic from corrosion, oxidation and localized melting by insulating metal hot gases in engine core. The properties lifetime TBCs greatly influenced preparation technology, includes plasma spraying (PS), physical vapor deposition (PVD) laser re-melting (LM). In this paper, three technologies used to...
The initially formed defects in the mold of continuous casting are likely to be expanded and propagated subsequent processing. Based on principle material mechanics, a mathematic model is proposed describe development solidifying shell at meniscus for steel slab low‐carbon ([C] = 0.04%) that with cross‐section 1200 mm × 200 mm. influence mechanical stress induced by oscillation growth state primary dendrites evaluated combination non‐sinusoidal mode mold. results suggest caused bending tends...
In order to predict the influence on mechanical properties of concrete under sulfate erosion, based experimental data and Grey Theory, GM (1,1) model is used establish models C20, C40, C60, C80 crushing strength in natural drying process an erosion 6.9% concentration sodium sulfate, correlation calculated between grade, splitting tensile compressive strength. The calculation analysis shows that (1) for low (C20), most loss occurs initial stage deterioration, over time deterioration rate...
Based on the development of 20-inch large-area MCP-PMT, research a small, ultra-fast MCP-PMT is carried out with cooperation Institute High Energy Physics (IHEP), Chinese Academy Sciences and Northern Night Vision Technology Co., LTD (NNVT). The structural simulation optimization fast-time PMT was first performed by Monte Carlo-based approach. Accurate measurements time performance greatest interest are then tested validated. IHEP NNVT have successfully developed single-anode, 4x4-anode...
Three-dimensional finite element analysis was made on the transverse joint stress state of concrete pavement slab with void underneath using ANSYS.

This study delves into the effects of carbonation curing and autoclave–carbonation on properties calcium oxide–belite–calcium sulfoaluminate (CBSAC) cementitious material aerated concrete. The objective is to produce concrete that adheres strength index in Chinese standard GB/T 11968 while simultaneously mitigating CO2 emissions from cement factories. Results show compressive CBSAC with different regimes (autoclave curing, curing) can reach 4.3, 0.8, 4.1 MPa, respectively. In delaying...
This work used CBSAC (CaO-C2S-C4A3S(_) cementitious materials) to replace cement and quicklime as the primary calcium sources in aerated concrete. The effects of different curing methods on physical-mechanical properties, carbonation degree, pH value concrete were investigated.
