The workshop will cover the major areas related to materials science and engineering. The subject areas may include, but are not limited to the following domains:
- Title: Ultrafast Dynamics in Solids Probed by Time-Resolved XUV-ARPES
By: Dr. Michael Bauer
Time- and angle-resolved photoemission spectroscopy is the potentially most direct and comprehensive, energy- and momentum-selective probe of ultrafast processes in solids that couple to the electronic degrees of freedom. Angular resolution enables one in this context to monitor the temporal evolution of the valence electronic band structure of a solid at selected— and possibly critical—points in momentum space [1]. The application of XUV photon pulses enlarges the accessible momentum regime considerably so that band structure transients within the entire Brillouin zone can be recorded [2, 3].
After a general introduction into the experimental technique [4], I will discuss recent results of our group on the ultrafast dynamics in solids as probed by time-resolved XVU-ARPES. Examples include hot electron dynamics in graphite [5] and semiconducting transition metal dichalcogenides (TMDC’s) [6), ultrafast melting processes of charge-ordered phases in TMDCs [3, 7], and coherent phonon dynamics in the iron-pnictide BaFe2As2 [8].

- Title: Understanding the Coupled Electrochemical-Mechanical Behavior of Materials for Improving the Performance and Durability of Lithium Ion Batteries
By: Dr. Yang-Tse Cheng
With an increasing demand for higher energy and power density of lithium ion batteries (LIBs), the coupled electrochemical-mechanical degradation of electrode materials becomes a more pressing problem. In particular, fracture and delamination of electrodes can occur during repeated charging and discharging of LIBs. An improved understanding of the mechanical behavior of electrode materials, which often evolves with the state-of-charge and cycle number, is therefore necessary for improving the performance and durability of LIBs and other types of batteries. In this presentation, I will provide an overview of our recent work on using three complementary measurement techniques: (1) in situ electrochemical nanoindentation, (2) peel adhesion and cohesion test, and (3) electrode curvature measurement to help understand several coupled effects between mechanical and electrochemical behavior of materials on the performance and durability of high capacity electrodes. Examples include Si/polymer binder porous composite electrodes and lithium metal electrodes. These in situ characterization techniques may also be used to investigate the coupled electrochemical-mechanical behavior of a wide range of electrochemical energy storage materials under realistic working conditions.
- Title: MOF Design to Applications: Impact of Pore System Control on Gas Separations and Storage
By: Dr. Mohamed Eddaoudi
Metal-organic frameworks (MOFs) burgeoned in recent years due to effective design strategies (i.e., reticular chemistry) for their synthesis and their inherent [and readily interchangeable] hybrid, functional character.
Markedly, MOFs are amenable to design and manipulation for desired function and application. Several design strategies have been utilized and developed to target viable MOF platforms based on edge transitive nets, minimal edge transitive nets and our recently introduced merged nets: molecular building block (MBB) approach, hierarchical supermolecular building block, supermolecular building layer approaches (SBB and SBL, respectively).
Various key gas/vapors separations are accomplished using energy intensive processes as exemplified by the olefin/paraffin separation, an essential separation in chemical industry.
Here we present our progress in the development of functional MOFs to address some energy-intensive separations. Successful practice of reticular chemistry had afforded the fabrication of various chemically stable fluorinated MOF adsorbent materials (NbOFFIVE-1-Ni, also referred to as KAUST-7 and AlFFIVE-1-Ni, also referred to as KAUST-8). The restricted MOF window resulted in the selective molecular exclusion of propane from propylene at atmospheric pressure, as evidenced by multiple cyclic mixed-gas adsorption and calorimetric studies. Remarkably, KAUST-7 maintains its distinctive separation properties in the presence of water as a result of its high chemical and hydrolytic stability. [1]
The development of suitable storage and refining processes makes natural gas an excellent alternative fuel, but before its transport and use, natural gas must first be dehydrated. Conventional dehydration agents are energy intensive. KAUST-8 selectively removes water and requires just 105°C for regeneration of the dehydrating agent.[2]
The deliberate control of the pore aperture-size of various selected MOFs and its impact on various separations will be discussed.

- Title: Ion Incorporation and Transport through Thin Membranes for Energy Conversion and Storage
By: Dr. Fritz Prinz
Ion selective membranes are an essential component in any electrochemical energy conversion and storage device, including fuel cells and batteries.
My talk will begin with insights from nature. I will briefly describe charge transfer reactions across thin thylakoid membranes in biological plant cells. In particular, I will discuss experiments that allowed us to directly extract photosynthetic electrons from live membranes, subject to the stimulus of light.
Next, I will discuss proton conducting polymeric membranes and the need for noble metal catalysts for enabling the reaction of protons with oxygen at comparatively low temperatures and sufficiently high rates. Finally, I will elaborate on oxide ion conducting membranes that allow energy conversion in high temperature devices such as Solid Oxide Fuel Cells. I will use quantum simulations to help predict oxide ion transport rates, and study the use of dopants for improving ion conductivity.
- Title: Applications of Ultrafast Lasers in Materials Science and Engineering
By: Dr. Emmanuel Stratakis
This presentation will focus on the application of advanced ultrafast photonic approaches for novel materials synthesis, as well as for the development of advanced photonic techniques to probe at the nanoscale, which are issues of great interest in current materials science and engineering research [Adv. Mat., 29, 1700335 (2017)].
In particular, Nature inspires us in tailoring unique surface properties based on synergetic effects of chemical composition and multiscale surface morphology. We show that highly controllable, biomimetic structures, exhibiting multifunctional water repellent, anti-reflection, friction reduction and photoresponsive properties can be directly written on metallic and dielectric surfaces upon processing with femtosecond laser beams of tailored polarization [Adv. Mat., 20, 4049 (2008) ; Biomicrofluidics, 5, 013411 (2011)]. It is shown that biomimetic laser structuring is a versatile method to tune neuronal cell adhesion, proliferation and orientation and can be promising for biomaterial scaffolds for neural tissue regeneration [Biomaterials 67, 115-128 (2015)].
The second part of the presentation will focus on the application of advanced ultrafast laser based techniques for the synthesis and diagnostics of materials and components in photovoltaic, light emitting, chemical sensing and energy storage systems. In particular, the pulsed laser assisted fabrication of transparent graphene electrodes and interlayers for flexible photovoltaic devices, is demonstrated [Adv. Func.l Materials, 25, 2213 (2015)]. Furthermore, we present a fast, non-destructive and roll-to-roll compatible photochemical method for the doping of graphene [Nanoscale, 6, 6925-6931(2014)] and transition metal dichalcogenide (TMD) crystals [2D Materials 6, 015003 (2018)]. By tuning the laser exposure time, it is possible to tune the doping levels to values that are suitable for photovoltaic and light emitting devices respectively. In parallel, our recent advances in the synthesis [Nanoscale, 9, 18202 (2017)] and femtosecond time-resolved spectroscopic diagnostics of perovskite nanocrystals as well as their composites with polymers [Chemical Science, 9 (42), 8121 (2018)] and phosphate glass are presented. The applications of the as-synthesized materials in perovskite photovoltaics [Nanoscale, 2018, DOI: 10.1039/C8NR10009H] sensors and energy storage systems [12] are demonstrated.
Finally, we present all-optical, non-invasive ultrafast laser-scanning optical microscopy methods to resolve, with unprecedented resolution, the crystallographic imperfections of atomically thin graphene, TMD and perovskite nanocrystals, via experimentally probing and theoretically interpreting their nonlinear optical properties [Light: Science & Applications 7 (5), 18005 (2018)].
- Title: Road to Ultra-Low Switching Energy Memories to Artificial Neurons
By: Dr. T. Venky Venkatesan
Memory devices are responsible for a significant fraction of the energy consumed in electronic systems- typically 25% in a laptop and 50% in a server station. Reducing the energy consumption of memories is an important goal. For the evolving field of artificial intelligence, the compatible devices must simulate a neuron. We are working on three different approaches towards these problems: one involving an organic metal centered azo complex, another involving oxide based ferroelectric tunnel junctions and the last involving real life neuronal circuits.
In the organic memristors that we have built on oxide surfaces, the device performance exceeds the ITRS roadmap specification significantly demonstrating the viability of this system for practical applications. More than that these organic memories exhibit multiple states arising from interplay of redox states and counter ion location studied by in-situ Raman and UV-Vis measurements leading to the possibility of neuronal systems. This organic family of molecules systems is extremely stable and reproducible- a significant departure from conventional organic electronics. On the oxide front the significant results are that ferroelectricity is seen even in two atomic layers of BaTiO3 or BiFeO3. Oxygen vacancy motion can also play an important role in changing the device characteristics leading to synaptic characteristics. Last but not the least, oxide surfaces can be utilized to force neurons to grow at specific places on a surface giving the potential for fabricating live neuronal circuits.
