Additive Manufacturing (AM)

Additive Manufacturing (AM), commonly known as 3D printing, is a process of creating objects layer by layer from digital models. It allows for the fabrication of complex geometries with high precision and material efficiency, reducing waste compared to traditional subtractive methods. AM supports a wide range of materials, including polymers, metals, and ceramics, and is widely used in aerospace, biomedical, automotive, and tooling industries. Research in AM focuses on improving material properties, process control, multi-material integration, and scalability for industrial applications.

Stress analysis of Microelectronic Packaging

Microelectronic packaging is a major discipline within the field of electronic engineering and includes a wide variety of technologies. It refers to enclosures and protective features built into the product itself, and not to shipping containers. It applies both to end products and to components. Packaging of an electronic system must consider protection from mechanical damage, cooling, radio frequency noise emission, protection from electrostatic discharge, maintenance, operator convenience, and cost.

Molecular Dynamics

Molecular dynamics (MD) is a computer simulation method for studying the physical movements of atoms and molecules, and is thus a type of N-body simulation. The atoms and molecules are allowed to interact for a fixed period of time, giving a view of the dynamic evolution of the system. In the most common version, the trajectories of atoms and molecules are determined by numerically solving Newton's equations of motion for a system of interacting particles, where forces between the particles and their potential energies are calculated using interatomic potentials or molecular mechanics force fields.

Composite Materials

A Composite material (also called a composition material or shortened to composite, which is the common name) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials.

Biomechanics

Biomechanics is the study of the structure and function of biological systems such as humans, animals, plants, organs, fungi, and cells by means of the methods of mechanics. Biomechanics is closely related to engineering, because it often uses traditional engineering sciences to analyze biological systems. Some simple applications of Newtonian mechanics and/or materials sciences can supply correct approximations to the mechanics of many biological systems. Applied mechanics, most notably mechanical engineering disciplines such as continuum mechanics, mechanism analysis, structural analysis, kinematics and dynamics play prominent roles in the study of biomechanics.

Nanomaterials

Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm. (the usual definition of nanoscale). Nanomaterials research takes a materials science-based approach to nanotechnology, leveraging advances in materials metrology and synthesis which have been developed in support of microfabrication research. Materials with structure at the nanoscale often have unique optical, electronic, or mechanical properties.

Renewable Energy

Renewable energy refers to power derived from natural sources that are replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. It plays a vital role in sustainable development by reducing fossil fuel dependence, mitigating climate change, and lowering environmental pollution. Key technologies include solar photovoltaics, wind turbines, hydroelectric systems, biomass converters, and geothermal plants. These systems demand interdisciplinary engineering for optimal efficiency, grid integration, and long-term durability. Integration also involves energy storage, smart grids, and advanced control strategies.

Density Functional Theory*(DFT)

DFT is a quantum mechanical modeling approach used to study the electronic structure of atoms, molecules, and condensed matter systems. It simplifies complex many-body problems by focusing on electron density instead of wavefunctions. Widely applied in materials science, DFT helps predict properties like energy, charge distribution, and bond strength. It is essential for designing catalysts, semiconductors, and nanomaterials. Current research aims to improve accuracy, efficiency, and applicability to complex systems.
