Gel-based nanomaterials have garnered significant scientific interest for their potential in small molecule encapsulation, release, and selective adsorption. This project aims to design, synthesize, and characterize new stimuli-responsive gel-based nanomaterials. By incorporating functional groups, these materials will exhibit responsiveness to stimuli such as light, heat, and pH.
The project involves the development of hybrid gel nanoparticles, known as nanogels, which combine a chemically cross-linked, polymeric hydrogel network with a stimuli-responsive physical hydrogel network formed from low molecular weight gelators (LMWGs). A key objective is to investigate the interpenetrating network formation of a stimuli-responsive physical hydrogel within the chemically crosslinked polymeric core of the nanogels. This unique structure will enable controlled release of small molecules, including drugs, in a triggered and potentially synergistic manner.
The synthesis of such materials presents a novel approach that holds promise for applications in drug delivery, water purification, and other fields. By harnessing the stimuli-responsive properties of these gel-based nanomaterials, more efficient and effective systems can be developed for targeted drug release and purification processes.

The development of compact laser light sources in the extreme ultraviolet (EUV) region holds tremendous potential for various applications, including chemical sensing, pathogen suppression, and computer processor lithography. The availability of compact EUV sources can revolutionize data processing and information storage by enabling compact and fast technologies in the field of photonics.
In Phase I of this project, significant progress has been made in the study of materials for EUV and device fabrication. Through rigorous research and calculations, key materials and physical phenomena that can generate EUV light have been identified. Furthermore, the existence of EUV plasmons in silicon, germanium, and diamond has been conclusively demonstrated through advanced techniques such as momentum-resolved electron energy loss spectroscopy (qEELS). The stability of these materials has also been validated through high-temperature characterization, overcoming various challenges in materials science.
Simultaneously, Paul Barclay's team has expanded their expertise in diamond nanofabrication to include photonic crystals. These capabilities, developed in collaboration between the Nanotechnology Research Centre and UAlberta's NanoFAB, play a pivotal role in enhancing and engineering EUV emission, which will be a primary focus in Phase II. The integration of diamond nanostructures in photonic crystals offers a platform for investigating EUV properties and opens avenues for future applications of the unique "quasi isotropic" etching technique to fabricate devices from other materials like germanium. Some of the materials investigated by qEELS in Barclay's lab have effectively bridged the gap between theoretical predictions and materials characterization.
Phase II of this project will concentrate on the fabrication and characterization of EUV devices, leveraging the knowledge gained in Phase I. This phase aims to further advance the understanding of EUV emission mechanisms and optimize device performance.

Nanomaterials hold the potential to make a tremendous impact across various sectors. While static interrogation of nanomaterial structure and composition has provided valuable insights, it is essential to acknowledge that nanomaterials are dynamic systems that undergo changes when exposed to external stresses. Consequently, there is an increasing need to develop new in operando characterization methods that enable the direct evaluation and characterization of nanomaterials in action.
Our team is uniquely positioned to meet this challenge, given our extensive expertise in nanomaterial design, preparation, characterization, and application. We possess access to powerful instrumentation, empowering us to lead groundbreaking advancements in the field.
One area where we aim to showcase our capabilities is in the design of state-of-the-art nanoparticle assemblies for improved energy storage systems and light-emitting devices. For instance, the utilization of emerging lower-dimensional materials, such as 2D van der Waals compounds (e.g., silicane, germanane, functionalized reduced graphene oxide), presents a compelling avenue for high-performance energy storage devices. Establishing new microscopy methods that probe the in operando evolution of nanomaterials, while complementing existing ex situ interrogation methods, will facilitate the development of novel functionalized nanoparticle and nanosheet assemblies. Moreover, it will enable the establishment of structure-property relationships, ultimately leading to improved high-performance clean energy storage devices.

The objective of this project is to demonstrate the proof of principle for ultrafast electron beam generation, electron wavepacket manipulation, and analysis using terahertz (THz) pulse electromagnetic fields. The primary focus is to investigate the fundamental science behind electron wavepacket control in THz fields and develop proof of principle instrumentation.
The successful implementation of this project will pave the way for a compact, terahertz ultrafast transmission electron microscope (THz UTEM). Such a THz UTEM would enable the observation of samples with temporal resolution comparable to atomic vibrations. This breakthrough could potentially introduce new electron spectroscopy modes capable of identifying materials based on their vibrational spectra at high spatial resolution.
To achieve our goals, we will employ a continuous electron beam that is manipulated by THz electric and magnetic fields. While this approach has been recently demonstrated using radio frequency fields, harnessing the power of high-intensity THz pulses offers several advantages. These include higher peak electric and magnetic fields, reduced size of the THz waveguide and resonator structures, and enhanced stability. These factors contribute to the feasibility of implementing our solution in 100 to 300 kilovolt electron microscopes, thereby enabling widespread applicability and impact.

Prions are infectious agents that can lead to devastating diseases such as bovine spongiform encephalopathy, chronic wasting disease, and Creutzfeldt-Jakob disease. The transmission of these pathogens occurs orally, with prions entering the body through the mucosa of the gastrointestinal tract. Unfortunately, there are currently no effective treatments available for these fatal diseases. However, there is a promising avenue of research focused on immunotherapy, specifically utilizing antibodies to target and clear prions from infected tissues.
Developing antibodies for prion clearance poses significant challenges due to the unique nature of prions. They are misfolded versions of a normal protein (PrP) that the body does not recognize as foreign, resulting in a limited antibody response. Furthermore, antibodies face obstacles in penetrating tissues and binding to prions with high affinity.
Traditionally, the focus has been on Immunoglobulin G (IgG) antibodies, despite the immune system producing five different antibody types. We propose that IgGs may not be the most effective antibody for targeting prions. They are naturally selected to function optimally in the bloodstream, have a short half-life, and exhibit limited efficacy at mucosal surfaces. In contrast, Immunoglobulin E (IgE) antibodies, primarily associated with allergic reactions, have demonstrated effectiveness at low concentrations for extended periods. They possess the ability to recognize and eliminate pathogens in the gastrointestinal tract.
Through reverse engineering, we have successfully developed an anti-PrP IgE antibody. This antibody has exhibited binding to FceRI, the high-affinity receptor for IgE, on human mast cells. Consequently, it triggers the release of proteases from mast cells, which can degrade PrP. This proof-of-principle study demonstrates the feasibility of a novel immunotherapeutic approach for acquired prion diseases, offering new possibilities for treatment.
