Asst Prof Hortense Le FerrandOrientation and aggregation of anisotropic microparticles under magnetic fields
Hortense@ntu.edu.sg

​Biocomposites often display outstanding properties (mechanical, optical, functional) that result from their internal microstructures. Using synthetic chemistry, however, allows exploring a wider range of properties and functions. In particular, ferromagnetic anisotropic particles distributed in a polymer could be a means for magnetically-triggered morphing composites with superior mechanics and electrical conductivity. To this aim, one should first understand how to build hierarchical microstructures with such elements. In this project, the student will study how ferromagnetic microparticles suspended in a viscous matrix respond to magnetic fields in terms of orientation and distribution. The tools will be optical microscope, rheometer, and magnetic fields.

Duration: 6 weeks

A/P Du HejunFabrication and characterization of ZnO thin film sensor for hard disk drives application
mhdu@ntu.edu.sg​As the recording density of hard-disk drives continuously increases, the spacing between the slider and the disk decreases quickly. If the spacing reaches 2-3nm or less, the contact between slider and disk can not be avoided completely. So in this project, ZnO thin film based sensor will be designed, fabricated and used to detect the contact between slider and disk in order to reduce the damage of head disk interface caused by contact. The main work includes:
 1) Deposition, optimization and characterization of ZnO thin film
 2) Design, fabrication and characterization of ZnO thin film based sensor.
Asst Prof Matteo SeitaHow deep does the rabbit hole go? Crystallography of corrosion pits in nickel
mseita@ntu.edu.sg
​Scope of the project: Corrosion is a phenomenon we are all familiar with. However the causes that drive corrosion damage
to initiate on specific locations across a metallic surface are rather obscure. Focusing on a pit-corroded nickel sample (see
figure below), the goal of this thesis is to quantify the extent of corrosion damage and to correlate it to the local sample
microstructure. Specifically, the student will analyze computer tomography (CT) scans of the sample to reconstruct the 3-D
geometry of the pits (see red framed micrograph below). This information will be correlated to electron backscatter
diffraction (EBSD) data to investigate the crystallography of each individual pit. Owing to the large number of pits in the
sample, it will be possible to identify crystallographic directions that are most susceptible to pit-corrosion via a statistical
analysis. This work will provide the experimental foundation for modeling and predicting localized corrosion on metallic
surfaces. The project will be carried out in collaboration with Texas A&M University (USA).
Area of research: Materials science.
Methodology: Theoretical; simulation.
Duration: Six month.
Special skills needed: Basic knowledge of crystallography. Students with knowledge of image processing techniques and
computer vision using the Matlab environment will be given priority.
​Asst Prof Matteo SeitaHow much permeable is a metal? Inferring aluminum permeability to liquid gallium from optical microscopy measurements
​​mseita@ntu.edu.sg ​Scope of the project: When aluminum and aluminum-based materials are put in contact with liquid metals—such as gallium
or mercury—they loose their mechanical integrity and disaggregate into their constituent crystallites. This phenomenon—
known as liquid metal embrittlement—is the result of the liquid metal (white in the micrograph below) permeating through
the internal interfaces of the solid material promoting their fracture (cracks appear black in the micrograph below). Liquid
metal embrittlement can have dramatic environmental and economic consequences in aerospace and nuclear applications.
In this project, we will follow the permeation kinematics of liquid gallium in pure aluminum samples, in situ, using optical
microscopy. Because of the large field of view and the fast image acquisition speed, optical microscopy will allow us to
capture a wealth of data and perform quantitative analysis of the gallium permeation speed as a function of the aluminum
sample microstructure. This work will be successfully used to infer novel microstructure designs for materials that resist
liquid metal embrittlement. Possible collaborations with MIT (USA) exist.

Asst Prof Matteo Seita​Quantitative analysis of surface texture in 3D printed metallic materials
​​​mseita@ntu.edu.sg ​Scope of the project: The surface roughness in 3D printed materials carry a wealth of information about the physical
phenomena involved during additive manufacturing and is known to strongly affect the performance of the produced
components. The goal of this project is to quantify the surface feature size, shape, and orientation—referred to as surface
texture—using novel optical microscopy techniques that were recently developed in our group. These techniques rely on the
collection of a series of optical micrographs taken under controlled illumination conditions [1]. Digital processing and
numerical analysis of the acquired dataset will be employed to reconstruct the 3D surface texture morphology. This
information will be expressed as a function of the process control variables used during additive manufacturing—such as
energy density and scanning strategy—to gain a better understanding on the manufacturing process and suggest possible
strategies to optimize surface quality.

Asst Prof Li HongConversion of Carbon Dioxide to Energy Sources Catalyzed by Graphene-Like Materials
ehongli@ntu.edu.sg

Area of research: electrochemical engineering, renewable energy.

Project description: Global energy consumption increases by 15% every decade while petroleum supply is declining gradually. Traditional energy source alternative to petroleum such as coal worsens the climate change by emitting more greenhouse gases. Greenhouse gas emission consists of mainly carbon dioxide (CO2) and methane emission, where CO2 contributes to more than 55%.  Greenhouse gas emission results in global warming that causes about 300,000 casualties every year. Global temperature would increase by 4 oC with current greenhouse gas emission trend, which could cause sea level rise about 10 meters. This would result in millions of people living in coastal area homeless. Carbon dioxide can be converted to energy carriers like carbon monoxide and hydrocarbons via electrochemical reactions; reducing the greenhouse gas emission and meanwhile producing useful energy sources. Graphene-like two-dimensional materials have great potential to act as superior catalysts for these reactions because their atomic thickness exposes most of their atoms to the environment, which could result in extraordinary chemical activity. In this proposed research, two-dimensional catalysts for conversion of CO2 to useful energy source will be investigated. Students, who would like to gain experimental experience in the areas of two-dimensional nanomaterials for environmental applications, are welcomed to apply.

Methodology: Student is expected to participate in every steps of the entire project including design of catalyst, synthesis of catalyst, fabrication of testing bed, and characterization of the catalyst. Only experimental work will be involved in the project.

Duration: Six-month internship is preferred.

Preferred background: material science and engineering, chemical Engineering, electrical engineering or related engineering disciplines. It is advantageous to have knowledge of electrochemistry, physical chemistry, semiconducting, nanomaterial synthesis and characterization.

Assoc Prof Huang Wei MinShape memory polymer/alloy composite for enhanced stiffness
MWMHuang@ntu.edu.sg ​Shape memory alloy and shape memory polymer are two typical shape memory materials with great potential in many applications. One of the most popular stimuli to activate shape memory is heat. Both shape memory alloy and polymer change stiffness upon thermal cycling, but in an opposite way. While shape memory alloy becomes harder upon heating, shape memory polymer becomes softer upon heating. The problem in many real engineering applications is that in the soft state, the material might be not stiff enough even to support its self-weight.

This project aims to experimentally investigate a simple solution by means of combining shape memory alloy and polymer together, so that the resulted composite is always able to, at least, support itself to avoid collapsing during operation upon thermal cycling.

This project is under smart materials and is mainly experimental investigation.

The duration of this project is up to 6 months.

Good hands-on skill is required, and interest to explore new ideas is a big plus.

Assoc Prof Lee Yong TsuiAccurate Measurement of Objects in a Single Photograph
mytlee@ntu.edu.sg

​We have developed the technology for recreating 3D models from line drawings. For accurate drawings, the reconstructed model is accurate, and therefore can be used for making measurements from the model. We now wish to apply this technology to photographs, which capture images accurately, though usually with some distortions due to lens imperfection. Work is needed in finding the relevant edges in a photograph for the object and then recover the 3D model. While edge finding from raster images is well understood, accurate edge finding remains a difficult problem as occlusion and artefacts like shadows and textures in images pose difficutlies.

Assoc Prof Xiao ZhongminElastic-plastic Fracture and Fatigue study for New Alloys Made by Additive Manufacturing (AM) Methods
mzxiao@ntu.edu.sg

​Typically, it is not possible to simultaneously enhance strength and toughness of engineering alloys, except via microstructural engineering. In the proposed project, 3-dimensional fracture mechanics and fatigue analysis will be conducted to investigate the possible failure modes, and more importantly, the possible methods to prevent such failure occurring for advanced metal alloys made byadditive manufacturing (AM) methods. It is widely recognized that the existing fracture assessment procedures which are based on load-controlled method, are not explicitly designed for situations with large plastic deformation, making the fatigue life prediction of new metal materials unreliable.  In this proposal, extensive parametric studies will be carried out to investigate the influences of various parameters, such as meso structures, grain size, alloy contents, etc. on the strength and toughness of new-made alloy materials.
