Sticking probability is a term used in various scientific and technical contexts, particularly in the fields of physics, chemistry, and materials science. It refers to the likelihood or probability that particles (such as molecules, atoms, or nanoparticles) will adhere to a surface upon collision, rather than bouncing off or reacting in a different manner.

The Split-Hopkinson Pressure Bar (SHPB) is an experimental apparatus used to measure the dynamic mechanical properties of materials, particularly in high-strain-rate conditions. It is commonly employed in materials science and engineering to study how materials respond under rapid loading conditions, such as impacts or explosions. The SHPB consists of two long, slender bars (the incident bar and the transmitter bar) and a specimen placed between them.

Stacking-fault energy (SFE) is a material property that describes the energy associated with the formation of stacking faults in crystalline materials. A stacking fault is a type of planar defect that occurs in the crystal structure when there is an incorrect sequence in the arrangement of atoms in a close-packed plane. This misalignment can arise from various processes, such as dislocation movement, phase transformations, or interactions with other defects.

The Sublimation Sandwich Method is a technique used primarily in the context of heat transfer printing, particularly for creating high-quality designs on materials such as textiles. This method employs sublimation ink, which transitions from a solid to a gas without passing through a liquid state, allowing for vibrant and durable prints. ### Overview of the Sublimation Sandwich Method: 1. **Preparation**: This technique requires sublimation paper printed with the desired design using sublimation ink.

In materials science, the term "substrate" refers to a base material or surface on which other materials are deposited, grown, or assembled. Substrates play a crucial role in various applications, including semiconductor manufacturing, coatings, thin-film technologies, and biomaterials.

The concepts of "stopping power" and "range" of ions in matter are related to how charged particles, such as ions, lose energy as they travel through a material and how far they can penetrate before coming to a stop. ### Stopping Power **Stopping power** refers to the ability of a material to slow down and absorb the energy of charged particles, such as ions or electrons, as they pass through it.

Striation in the context of fatigue refers to the appearance of visible, parallel lines or streaks on the surface of a material, often metals, that have been subjected to cyclic loading conditions. This phenomenon typically occurs when materials experience repeated stress and strain over time, leading to microstructural changes. The striations are indicative of the material's response to fatigue and can be seen under a microscope.

Structural integrity refers to the ability of a structure to withstand its intended load without failing due to rupture, deformation, or fatigue. It encompasses the safety, reliability, and performance of various types of structures, including buildings, bridges, dams, and mechanical components. Ensuring structural integrity involves understanding the materials used in construction, the loads a structure will encounter (such as dead loads, live loads, environmental loads), and the design principles that govern how these structures respond to stress and strain.

Vegard's law is a principle in solid-state physics that describes the relationship between the composition of a solid solution and its lattice parameters. Specifically, it states that the lattice constant (or parameter) of a solid solution is a linear function of the composition of its constituents. In simpler terms, when two or more different materials are mixed to form an alloy or a solid solution, the resulting lattice structure will have a lattice parameter that can be predicted based on the proportions of the constituent materials.

Strength of materials, also known as mechanics of materials, is a branch of engineering and materials science that studies the behavior of solid objects subject to stresses and strains. It focuses on how different materials deform (strain) under various types of loading conditions (such as tension, compression, shear, and torsion) and how they fail.

Syntactic foam is a composite material that consists of a polymer matrix filled with hollow microspheres or microballoons. These microspheres are often made from materials like glass or ceramics, and they provide the foam with unique properties. The combination of the polymer matrix and the embedded microspheres results in a lightweight, buoyant, and strong material.

In mineralogy, "tenacity" refers to the resistance of a mineral to deformation, breaking, or being separated. It describes how a mineral reacts to stress or pressure, particularly in terms of its physical properties. Tenacity can be classified into several categories based on how a mineral responds to different types of stress: 1. **Malleable**: Can be hammered into thin sheets or shaped without breaking (e.g., gold).

Terahertz nondestructive evaluation (THz NDE) is a technique that utilizes terahertz (THz) radiation, which falls in the frequency range between microwave and infrared radiation (approximately 0.1 to 10 THz), to inspect and analyze materials and structures without causing any damage. This method exploits the unique interaction of THz waves with different materials, enabling the detection of flaws, moisture content, and other properties.

Superplasticity refers to the ability of certain materials, typically some metals, to undergo very large strains (a significant amount of plastic deformation) without fracturing, often exceeding 1000% elongation. This remarkable property is observed at elevated temperatures, typically above 0.5 times the melting temperature of the material in absolute terms (Kelvin). The phenomenon of superplasticity is characterized by a fine-grained microstructure, which allows the material to deform extensively under a constant tensile load.

Surface diffusion is a process in which atoms or molecules move along the surface of a solid material. This movement occurs as a result of thermal energy, allowing species to hop from one site to another on the surface. It plays a critical role in various physical and chemical phenomena, including thin film growth, adsorption/desorption processes, catalysis, and sintering.

Surface modification refers to various techniques and processes used to alter the physical, chemical, or biological properties of a material's surface in order to enhance its functionality, performance, or aesthetic appeal without changing the bulk properties of the material itself. This can be critical in many applications, including materials science, engineering, and biotechnology.

Surface states refer to electronic states that exist at the surface of a material, particularly in solid-state physics and materials science. Unlike bulk states, which are found in the interior of a material, surface states arise due to the termination of the periodic potential created by the lattice of atoms in a solid. When the material's surface is exposed to the environment, the atoms at the surface are less coordinated compared to those in the bulk, leading to a distinct electronic structure.

Testing of advanced thermoplastic composite welds involves evaluating the integrity and performance of welded joints made from thermoplastic composite materials. These materials, which combine the properties of thermoplastics with reinforcing fibers, offer high strength-to-weight ratios, flexibility, and resistance to environmental degradation. However, they present unique challenges in welding and joining processes compared to traditional thermosetting composites or metals.

Applied nanoscience is the field of study that focuses on the practical applications of nanotechnology and nanomaterials, which typically have dimensions ranging from 1 to 100 nanometers. This interdisciplinary field combines principles from physics, chemistry, biology, materials science, and engineering to manipulate and harness materials at the nanoscale for various applications.

The Journal of Thermal Stresses is a peer-reviewed academic journal that focuses on the field of thermal stress analysis and related topics in materials science and engineering. It publishes original research articles, reviews, and theoretical and experimental studies that explore the effects of thermal loading on materials, structures, and devices. Topics covered in the journal may include heat transfer, thermal expansion, phase changes, thermal fatigue, and the mechanical properties of materials under varying thermal conditions.
