Title: What is Life? Towards Imaging the Molecular Machinery of the Cell
Abstract:
The posed quintessential question is not cast as an origins of life issue here but rather directed towards understanding the underlying physics by which chemistry breathes life into otherwise inanimate matter. The real issue is how chemistry scales in complexity up to the level of biological systems. For even relatively small molecules (e.g., 10 to 100 atoms), there are an enormous number of possible nuclear configurations that could propagate the system from one molecular form to another during a chemical event. Chemistry is inherently a high dimensional problem of order 3N (N= number of atoms) and highly nonlinear in sampling rates for different reaction trajectories. To explain the observed time scales for chemistry and biological processes, there must be an enormous reduction in dimensionality at the barrier crossing region, controlling the kinetics, in which a few key modes direct the chemistry – irrespective of complexity. The challenge is to try to unearth these motions and to understand a priori which motions are directing the chemistry and thereby biological functions. With the recent advent of ultrabright electron sources using femtosecond laser photoinjection, it is now possible to directly observe the atomic motions involved to complete the picture. Based on model systems, a simple concept is introduced to understand the spatially correlated forces leading to generalized reaction mechanisms, which makes chemistry a transferrable concept. Several atomically resolved molecular movies will be presented to dramatically show this effect and the concept of key reaction modes. The problem is much more challenging within cells where the number of possible interactions becomes truly astronomical, as will be discussed. The lessons learned above give hope to find similar dynamically coupled spatial correlations, but these will be related to free energy gradients that arise within intracellular architecture. New technologies, based on the space charge limits mastered in ultrabright electron source development, will dramatically improve ion collection for laser based spatial imaging mass spectrometry that will enable us to look inside the cell to directly observe the driving forces for living systems, i.e., to quantify life. This prospect promises to fill in the gaps between genetic information and protein expression, from the blue print to the actual execution of the code. The light matter interactions being exploited and technological requirements under development to achieve this Moon Shot for Biology will be discussed as part of proposal for a strategic initiative to map the cell.
Biography:
R. J. Dwayne Miller has published over 300 papers, notably contributions leading to the development of ultrabright electron sources to light up atomic motions. His group were the first to achieve the long-held goal to watch atomic motions during the defining moments of chemistry and have attained the fundamental space-time limit to imaging chemistry. His research accomplishments have been recognized with numerous awards including the National Science Foundation Presidential Young Investigator Award (USA), Sloan Fellowship, Guggenheim Fellow, Dreyfus Award, Polanyi Award, Royal Society of Canada (RSC) Rutherford Medal, Chemical Institute of Canada (CIC) Medal, American Chemical Society (ACS) E. Bright Wilson Award, and most recently the European Physical Society (EPS) Award in Laser Science for “Achieving the Fundamental Limit to Min. Invasive Surgery with Complete Biodiagnostics”. The enabling physics came from the first atomic movies on strongly driven phase transitions to determine the parameters for completely uniform forces for material removal without shock wave formation. These latter concepts are now going to clinical trials with the promise of enabling scar free surgery with broad medical applications. He is also a strong advocate for science promotion earning the RSC McNeil Medal (2011) and the Helen M. Free Award of the ACS for founding Science Rendezvous, now in its 18th year, aimed to make science accessible to the general public, including remote northern communities, with over 200,000 attendees (>6000 volunteers) annually. He is a Fellow of the CIC, OSA, RSC, RSC (Chemistry, UK) and was inducted as a Fellow of the Royal Society in 2023.

Title: Hollow core fibres: innovation at a faster speed
Abstract:
For decades, hollow core fibres have been a fascinating tool for scientists, enabling long distance light guidance in any gas and innovative experiments exploiting the long light:gas interaction length. For a long time, their optical performance failed to reach the requirements of optical communications. Recently though, thanks to nested antiresonant designs, the loss, modal purity and spectral bandwidth of these fibres has reached parity with, and in many instances improved the performance of, conventional glass-guiding telecoms fibres. Global interest in the technology is on the rise and, while there are still substantial challenges to be solved before it can achieve widespread commercialization, it is hard to believe that it will not find some application in optical communication networks of the future. In this talk we will review state-of-the-art, opportunities and challenges of the hollow core fibre technology.

Title: Architecture Evolution, Building Green All-Optical Networks in the Intelligent Era
Abstract:
The unprecedentedly rapid development of AI large models in the past two years has created a huge demand for computing power and AI clusters. On the user side, AI is becoming widely used. Intelligent mobile terminals, like AI phones and AI PC, are becoming available. Intelligent home applications, such as entertainment, lighting, security, and cleaning also step into people's daily life. At the same time, AI applications in various industries are gradually commercialized, such as AI-based news and advertisement push. To meet the requirements of these intelligent applications, the architecture evolution trend, of all-optical networks is critical. DC-centric optical networks will evolve towards low power, high bandwidth, low latency, high reliability and flexibility. Home, office, and manufacturing are also calling for high-quality optical networks. People's requirements for networks will evolve from bandwidth-driven to experience-driven. These evolutions will create a new green all-optical network to meet the diverse and high-quality requirements of the intelligent era.
