Due to its unique structure, graphene exhibits remarkable mechanical properties.
This structure not only contributes to its mechanical strength but also underpins other exceptional characteristics, such as thermal and electronic properties.
The increased magnetic moment found in the pyrolic-pyridinic system is due to two principal factors: the presence of an unpaired electron and the consequences of excessive orbital overlap.

Now let us briefly determine these effects; Oxidation Oxidation is one of the most serious factors acting on the gas turbine’s service life and can be determined as the reaction of materials with oxygen in 2-4 atm. partial pressure [1].
Material Properties of MoSi2.
Conclusion By considering the room temperature fracture toughness and creep behaviour at 1200 oC along with the oxidation resistance around 900 oC we can see a wide spectrum of mechanical and environmental properties have been measured in order to establish feasibility of an MoSi2 composite with Si3N4 particulate.

Using its unique surface effect and the small size effect, zero-valent iron (ZVI) nanoparticles can increase the reactivity and efficiency, so the mechanical properties, etc. are very different from ordinary materials, it has a unique advantage catalytic, adsorption, and other new features, especially in the groundwater remediation.
Therefore, in recent years, nano-iron be noticed more and more on the preparation of materials, process and characterization of the microstructure and properties, and made a lot of new progress.
Our work select wet chemical method to prepare zero-valent iron (ZVI) nanoparticles, study the influence on the product properties of the preparation process and the addition of different dispersants.
SEM characterization results.Nanoparticles themselves lack coordination atoms of near the surface, with a high activity, which makes the existence of nano-particles is different from the conventional role of particles in the spontaneous trend, it is easy to internal factors of aggregation of nanoparticles.
Because zero-valent iron (ZVI) nanoparticles have a magnetic, they are more likely to reunite in aqueous solution, which affect their application.

Therefore, based on the computer hardware and software technology as a strong technical support, from the mechanical properties of the basketball, we simulate the flight trajectory of basketball shooting process, and obtain the good simulation results, which provide technical support for basketball players.
Mechanics Modeling and UDF Program Design in the Basketball Flight Using computer methods to simulate the basketball flight, it needs to s to build basketball mechanical model, including basketball itself and air flow field.
Basketball deformation will affect the flight trajectory of basketball, thus affecting the basketball shooting effect.
Therefore, it needs to consider the factors of shooting speed and angle of shooting in basketball shooting process, adjusting the shot, so as to improve the percentage of hits.

Introduction Functional properties of many products and their elements depend not only on their capability to carry the mechanical loads by the element's entire cross-section from the material used or on its physical and chemical properties, but very often - or mostly - on its structure and properties of its surface layers.
The micro-crevices network is very developed on the Ti(C,N)+Al2O3+TiN and TiC+Ti(C,N)+Al2O3+TiN coatings surfaces, compared to the other CVD coatings, which is the decisive factor affecting the examined inserts' functional properties (Fig. 2b).
Therefore, these basic factors impede the tool flank wear rate for the coated tool materials.

The chemical properties of palm kernel shell ash can affect the strength of high-quality concrete [16-18].
Pozzolan Reactivity: The reactive properties of palm kernel shell ash, in its reaction with calcium hydroxide, will affect its ability to strengthen concrete.
Here are some factors that can affect the strength of high-quality concrete.
Additionally, it can act as a partial substitute for cement, reducing the need for additives and improving the mechanical properties of concrete.
Crack Risk Reduction: the compounds in coal ash can help reduce the risk of cracks in concrete by improving their mechanical and thermal properties.

Introduction Nanofibers have been widely used as wound dressings [1-4], because they have a structure similar to native tissue, interesting mechanical properties [1], high surface area to volume ratio and high pore structure.
Morphology of the fibers produced by electrospinning depends on various factors: (a) material variables such as molecular weight and polymer concentration, ionic salts, and surfactants, (b) process variables for example applied voltage, waveform and polarity, electric field strength, flow rate, distance between tip and collector, and temperature, and (c) equipment variables including needle size and shape, collector assemblies, and auxiliary electrodes [7].
Photographs of resulting PVA/chitosan nanofibers on the collector under different applied electric potentials: (a). 10 kV, (b). 12 kV, (c). 15 kV The applied voltage also affects the thickness of the nanofibers membranes.
The charge on the jet stream is the key factor affecting the morphology of the resulting fibers.

More specifically, we show that leaf shapes are affected by genes and external environment in different species; and affected by leaf vein and leaf distribution In the same species.
Fig. 1: The reason of the different shape In macroscopical level, genes and external environment are the two key factors to effect the leaf shapes in different kinds of tree.
●Transform into spines to protect the plants, such as cactus In microscopic level, veins and the distribution of leaves affect the shape of the leaves in the same kind of tree.
Meanwhile, these three traits characterize properties of the terminal venation network: vein distance, density and loopiness.
High loopiness suggests more redundant paths for water to circumvent damage, and more ways to stop the propagation of a mechanical tear.

You can use any unit in project analysis . 1.2 The calculation model The distribution morphology and size of soil pressure in different properties of sand beyond the pipe culvert are researched.
Because of the different sand strength in soils ,The mechanical properties of sand affected by its components is different.
So, the elastic modulus and Poisson's ratio are considered as the variable to simulate the change of sand properties.
Lateral boundary node is free to move in vertical direction, which is applied in horizontal direction constraint; the bottom boundary nodes can not move in Vertical, horizontal direction, which is put all direction constraint; the filling surface is free and does not impose constraints; The contact unit is arranged in the culvert and soil contact boundary, the target unit select Targe169 units, the contact unit is the Conta171 unit, 0.4 is taken as the friction coefficient of the contact unit. 1.3 Experimental design The numerical simulation experiment design includes two factors: soil elastic modulus (E) and soil Poisson's ratio (µ).
When the Poisson's ratio is as an invariant factor, the elastic modulus consists of three levels: 7×106Pa, 15×106Pa, 20×106Pa; When the elastic modulus is as an invariant factor, the Poisson's ratio is made up of three levels: 0.32, 0.30, 0.35.
