Designing functional particles via spray drying
Cordelia Selomulya*
School of Chemical Engineering, UNSW Sydney, Australia*E-mail: cordelia.selomulya@unsw.edu.au

Spray drying is a versatile method to generate functional particles for different applications,depending on feed material properties, formulation, and pre- and post-treatments. This talk will
provide an overview of the design and assembly of functional particles, including thermal
sensitive and bioactive particles, microparticles for controlled release and microencapsulation,
magnetic and fluorescent composites, and mesoporous microspheres with hierarchal
structures and properties superior to those observed on nanomaterials via spray drying [1]. In
particular, the use of microfluidic spray drying that can generate uniform particles with tightly
controlled characteristics and targeted properties helps us to develop the understanding of
how particles with different microstructures are formed, and how the physicochemical
properties of feed materials are related to the functionality of the particles. The underlying
principles of particle formation mechanisms are applicable for diverse particles such as coreshell, mesoporous, and magnetic particles, with examples given for applications in targeted
drug delivery, catalysis, bio-adsorption, functional foods, and others [2-3]. The knowledge isuseful for designing spray-dried particles for specific applications, including new formulationsof spray-dried powders for commercial productions [4].

The use of optical techniques in electrophysiology research has recently garnered significant
attention, as numerous efforts strive to develop cutting-edge neural interfaces. Opticalelectrodes (optrodes) utilizing liquid crystal technology have exhibited great promise fordetecting extracellular activity in excitable cells by passively transducing electrical impulses
into quantifiable optical signals [1]. Our research team presents a new flexible version of thistechnology to enable better interfacing with soft tissues through incorporating polymericmaterials and components.
The findings underscore the successful development of a scalable fabrication process forflexible optrode sensors, resulting in a functioning prototype with remarkable mechanicalflexibility and no impedance-related complications. The functional characteristics of the flexible
sensor are comparable to its rigid counterpart, indicating its potential for future biopotential
activity recording. These outcomes not only offer valuable insights into more effective solutions
for electrophysiology recording but also broaden the range of applications for optrode sensors
to include direct interfacing with various biological tissues.

Black coal can be green: CO2 geo-storage inunderground coal seams

Due to the cumulative release of greenhouse gases into the atmosphere, the Earth is warmer
than ever, causing more large scale and irreversible climate changes. To achieve net zero
emission goal to mitigate the global warming issues, CO 2 is captured from air and thenpermanently stored in underground formations, for example underground coal seams. Different
with other geological materials, coal naturally has a high adsorption affinity for CO 2 , whichmakes the abundant reserves become a good option for CO 2 geological storage site.
However, the process of injecting CO 2 into underground coal seams for geological storage isa highly complicated process, which is yet to be understood in depth. Due to its complex
heterogenous structure, the underlying multiphysical phenomena are spatially localised as wellas time-dependant. In this work, Positron Emission Tomography (PET) imaging, a nuclear
imaging technology, is performed to reveal time-lapse CO 2 flow kinetics in coal by using [11C]
CO 2 as the radioactive tracer [1]. From PET images, the processes of CO 2 spreading, trapping,migrating and interacting in coal are all observed. Meanwhile, a hydro-mechanical-thermal
coupled model is developed to simulate multiphysics CO 2 flow in coal [2]. The simulation is
performed based on the digital coal structure obtained by X-ray computed tomography (microCT) imaging. By combining PET image data with modelling results, we can fill knowledge gaps
from the fundamental basis, and enhance CO 2 geological storage efficiency and safety in coalseams.

An urgent need for sustainable and healthy food systems accelerates the development ofsuperior plant-based ingredients and manufactured food products based on plant ingredients.
Plant proteins serve as the primary macronutrient in plant-based foods, while there still remain
issues in consumer behavior towards plant-based alternatives due to their unsated taste,texture, and quality. Plant/dairy protein blends have recently emerged as novel ingredients
suitable for food application with improved functionality in addition to their textural, sensory,and nutritional properties. In this presentation, processing strategies for plant/dairy protein
blends are introduced to improve the protein functionality, enabling their uses as emulsifiers
and carriers for lipophilic bioactive compounds. State-of-the-art spectroscopic techniques suchas microfluidic modulation spectroscopy and synchrotron infrared microspectroscopy wereapplied to analyze protein structure and composition. Innovative food processing technologies
could broaden the application of plant/dairy protein blends to emulsions and functional particles.

Speech is one of the most natural ways of transmitting information, and speech-based emotion
recognition (SER) facilitates more seamless human-machine interactions. Emotion is complex,
ambiguous and it evolves. This study addresses the intricacies of emotion recognition with adual focus: the exploration of emotion ambiguity and the modeling of temporal dynamics withinemotional attributes, subsequently integrating them into SER systems. The research develops
probabilistic frameworks to capture the ambiguity in continuous emotional labels and employs
dynamical models to capture the temporal dynamics. Innovative machine learning and deeplearning frameworks have been developed to capture these complex emotional characteristics,
providing valuable insights for the field of emotion recognition.

Solar-driven green fuels production has emerged as a promising solution to address
the challenges posed by energy crisis and climate change. By harnessing theabundant and renewable energy from the sun, this approach aims to convert solar
energy into valuable chemicals and fuels using water, air, CO 2 emissions and wastes.
However, the technology is still pending for improvement and optimization to maximize
solar utilization efficiency.
This study focuses on designing novel photovoltaic devices and highly efficient
catalysts to develop a comprehensive (photo)electrochemical system capable ofproducing target products at an industrial relevant rate. In-depth investigations,employing advanced characterizations, particularly in-situ techniques, have been
conducted to gain a thorough understanding of material properties and complex
reaction mechanisms. Furthermore, modeling calculations and feasibility analyses
have been employed to enhance theoretical understanding and evaluate economic
viability, respectively. The advancements of this work in materials science, energy
conversion technologies, and system engineering are paving the way for solar-driven
synthesis in rational design and practical application. This study will contribute to thetransition towards a carbon-neutral and sustainable energy society.

The effect of varying the weight percentage composition (wt.%) of low-cost expandable
graphite (EG), ammonium polyphosphate (APP), fibre glass (FG) and vermiculite (VMT) in
Polyurethane (PU) polymer was studied using a traditional intumescent flame retardant (IFR)
system. The synergistic effect between EG, APP, FG and VMT on the flame-retardant
properties of the PU composites was investigated using scanning electron microscope (SEM),
thermal gravimetric analysis (TGA), tensile strength tests, and cone calorimetry. The IFR that
contained PU composites with 40 wt.% EG displayed superior flame-retardant performancecompared with the composites containing only 20 wt.% or 10 wt.% EG. The peak heat releaserate, total smoke release (Fig. 1) and carbon dioxide production from the 40 wt.% EG sample
along with APP, FG and VMT in the PU composite was 88%, 93% and 92% less than the PU
control sample, respectively. These new PU composite materials provide a promising strategy
for producing polymer composites with flame retardation and smoke suppression for
construction materials.

From the supply side, the rapid evolution of Photovoltaic (PV) technologies and theproliferation of PV systems emphasizes the need for more efficient and cost-effective
monitoring strategies to ensure reliable operation and energy efficiency [1].

Figure 1. Work for energy transition at both supply and demand sides.

On the demand side, energy communities appear as new participants that search theaggregation of energy resources to offer the flexibility required by the grid through energy
storage and demand response (DR) capabilities [2]. Energy can be managed/scheduled
cooperatively at the community level from a local economic and environmental perspective.
Users within the community can obtain energy cooperation benefits, which requires more
active participation in DR. Community energy storage (CES), an alternative to grid-scale andsingle-household scale storage solutions, is now gaining more and more attention to resolving
the cost and usage inefficiency of private energy storage.

A light-induced convection generated by laser irradiation enabled us to trap bacteria in the
micropores on honeycomb polymer film (Fig. 1A). Fig.1B shows the fluorescence image of live
bacteria when photothermal assembly was performed. The survival rate was maintained athigh levels of around 80 to 90%. Next, we evaluated the electrochemical application potentialof our proposed system using a representative electricity-producing bacterium. As the numberof irradiation points increased, the current density increased almost proportionally (Fig. 1C). In
addition, this presentation includes recent achievements in the rapid and specific detection ofbacteria by using the photothermal assembling technique.

This study introduces Personal Mobility Vehicles (PMVs) as a means of individualtransportation. In particular, component technologies for self-driving to improve safety andconvenience will be discussed. There are following important aspects of autonomous drivingof PMVs. 1. To provide assistance according to the dynamics of each PMV. 2. The mass ratioof humans to PMVs is large and human behavior is important to the stability of the entire
system. 3. The dynamics of the system are different between a human driver driving the vehicle
on his/her own intention and a ride in automated driving. For example, Fig. 1. shows the driver’s
center of gravity position during sudden braking. The left figure shows the case braking by thedriver’s intention and the right is the case braking by the stand-up type PMV. It is shown thatthe sudden braking by the PMV largely affects the driver’s posture stability.

Dendrimer is a synthetic polymer with well-defined structure. Because various compounds canbe conjugated at a single dendrimer molecule, dendrimers are a potent multifunctional
nanocarrier (Figure 1). Stimuli-responsive polymers are useful as smart materials. We haveshown that carboxy-terminal PAMAM dendrimers modified with a hydrophobic amino acid,phenylalanine (Phe), showed dual pH- and temperature-sensitive properties [1]. Goldnanoparticle (AuNP) was loaded in the stimuli-responsive dendrimer, which was applied as a

This study focused on a biofuel supply chain and used evolutionary game theory to clarify whatstrategies a farmer (F), a biorefinery (B), and the government (G) would choose in a long termwhen G intervened to promote biofuel production (BP) and converted to second-generation
biomass (2G-Bio). In cases of government intervention to promote BP and conversion to 2GBio, this paper assumed that F, B, and G took two behavior strategies: F took two behavior
strategies of producing 1G-Bio (F1) or producing 2G-Bio (F2), and B took two behavior
strategies of producing bioethanol (B1) or sales of biomass to a local markets (B2). G took two
behavior strategies of monitoring strategies of F and B (G1) or no monitoring them (G2). Using
Jacobian matrix in evolutionary game theory, it was judged which behavior strategy F, B andG always took as their long-term behavior strategy that was stable evolutionary stable strategy(ESS). Numerical analysis verified which combination of behavior strategy taken by eachmember was judged as ESS in a long term by giving numerical examples including sales price.

The research focuses on understanding how humans acquire motor skills and aims to develop
robotic support systems for motor learning. There is a growing interest in motion support robots,
like power-assist robots, which can supplement human strength or reduce the need for physicaleffort. However, it is crucial to consider the diverse needs of users, such as the elderly needing
increased physical activity or patients with neurological disorders requiring a balance between
assistance and self-effort during rehabilitation. Unquestioningly increasing assistance can becounterproductive, emphasizing the importance of finding the right balance tailored toindividual needs. The goal is to enable users to experience appropriately adjusted physicalexertion and instruction, facilitating the acquisition of effective motor skills through motion
learning support robots and systems developed by the research group.

DNA, which can be extracted from biomass, is an environmentally friendly, biodegradable
polymer with diverse functional groups including various heteroatoms such as nitrogen, oxygen,and phosphorus. It adopts a double helical structure through weak interactions such as
intramolecular hydrogen bonds, π-π interactions, and electrostatic interactions. In addition,
various functional groups in DNA form specific coordinate bonds and other interactions withvarious metal ions, thereby influencing the behavior of DNA. For example, the anticancer drug
cisplatin (cis-[PtCl 2 (NH 3 ) 2 ]) coordinates with adenine and guanine in DNA to exert its
anticancer activity. Other metal ions also interact with various functional groups in DNA, andthe binding and dissociation activities depend on the electronic state of the metal ions.
Therefore, by exploiting the interaction between DNA and metal ions, the structural propertiesof the DNA materials can be effectively manipulated, opening new avenues for innovative
materials using DNA derived from biomass. In this study, hydrogels crosslinked by naturally
occurring DNA and various
metal ions were prepared,withdifferent
