Oxygenic Photosynthesis in Far-Red Light: Strategies and Mechanisms
Annu Rev Phys Chem. 2024 Feb 21. doi: 10.1146/annurev-physchem-090722-125847. Online ahead of print.ABSTRACTOxygenic photosynthesis, the process that converts light energy into chemical energy, is traditionally associated with the absorption of visible light by chlorophyll molecules. However, recent studies have revealed a growing number of organisms capable of using far-red light (700-800 nm) to drive oxygenic photosynthesis. This phenomenon challenges the conventional understanding of the limits of this process. In this review, we briefly introduce the organisms that exhibit far-red photosynthesis and explore the differe...

Prebiotic Astrochemistry from Astronomical Observations and Laboratory Spectroscopy
Annu Rev Phys Chem. 2024 Feb 21. doi: 10.1146/annurev-physchem-090722-010849. Online ahead of print.ABSTRACTThe discovery of more than 200 gas-phase chemical compounds in interstellar space has led to the speculation that this nonterrestrial synthesis may play a role in the origin of life. These identifications were possible because of laboratory spectroscopy, which provides the molecular fingerprints for astronomical observations. Interstellar chemistry produces a wide range of small, organic molecules in dense clouds, such as NH2COCH3, CH3OCH3, CH3COOCH3, and CH2(OH)CHO. Carbon (C) is also carried in the fullerenes C60 a...

Phase Transitions in Organic and Organic/Inorganic Aerosol Particles
Annu Rev Phys Chem. 2024 Feb 21. doi: 10.1146/annurev-physchem-083122-115909. Online ahead of print.ABSTRACTThe phase state of aerosol particles can impact numerous atmospheric processes, including new particle growth, heterogeneous chemistry, cloud condensation nucleus formation, and ice nucleation. In this article, the phase transitions of inorganic, organic, and organic/inorganic aerosol particles are discussed, with particular focus on liquid-liquid phase separation (LLPS). The physical chemistry that determines whether LLPS occurs, at what relative humidity it occurs, and the resultant particle morphology is explained...

Single-Macromolecule Studies of Eukaryotic Genomic Maintenance
Annu Rev Phys Chem. 2024 Feb 21. doi: 10.1146/annurev-physchem-090722-010601. Online ahead of print.ABSTRACTGenomes are self-organized and self-maintained as long, complex macromolecules of chromatin. The inherent heterogeneity, stochasticity, phase separation, and chromatin dynamics of genome operation make it challenging to study genomes using ensemble methods. Various single-molecule force-, fluorescent-, and sequencing-based techniques rooted in different disciplines have been developed to fill critical gaps in the capabilities of bulk measurements, each providing unique, otherwise inaccessible, insights into the struc...

Chemical Kinetics in Microdroplets
Annu Rev Phys Chem. 2024 Feb 21. doi: 10.1146/annurev-physchem-052623-120718. Online ahead of print.ABSTRACTMicrometer-sized compartments play significant roles in driving heterogeneous transformations within atmospheric and biochemical systems as well as providing vehicles for drug delivery and novel reaction environments for the synthesis of industrial chemicals. Many reports now indicate that reaction kinetics are accelerated under microconfinement, for example, in sprays, thin films, droplets, aerosols, and emulsions. These observations are dramatic, posing a challenge to our understanding of chemical reaction mechanis...

Enhanced Sampling with Machine Learning
Annu Rev Phys Chem. 2024 Feb 21. doi: 10.1146/annurev-physchem-083122-125941. Online ahead of print.ABSTRACTMolecular dynamics (MD) enables the study of physical systems with excellent spatiotemporal resolution but suffers from severe timescale limitations. To address this, enhanced sampling methods have been developed to improve the exploration of configurational space. However, implementing these methods is challenging and requires domain expertise. In recent years, integration of machine learning (ML) techniques into different domains has shown promise, prompting their adoption in enhanced sampling as well. Although ML ...

Photon Upconversion at Organic-Inorganic Interfaces
Annu Rev Phys Chem. 2024 Feb 21. doi: 10.1146/annurev-physchem-090722-011335. Online ahead of print.ABSTRACTPhoton upconversion is a process that combines low-energy photons to form useful high-energy photons. There are potential applications in photovoltaics, photocatalysis, biological imaging, etc. Semiconductor quantum dots (QDs) are promising for the absorption of these low-energy photons due to the high extinction coefficient of QDs, especially in the near infrared (NIR). This allows the intriguing use of diffuse light sources such as solar irradiation. In this review, we describe the development of this organic-QD up...

Lipid Landscapes: Vibrational Spectroscopy for Decoding Membrane Complexity
Annu Rev Phys Chem. 2024 Feb 21. doi: 10.1146/annurev-physchem-090722-010230. Online ahead of print.ABSTRACTCell membranes are incredibly complex environments containing hundreds of components. Despite substantial advances in the past decade, fundamental questions related to lipid-lipid interactions and heterogeneity persist. This review explores the complexity of lipid membranes, showcasing recent advances in vibrational spectroscopy to characterize the structure, dynamics, and interactions at the membrane interface. We include an overview of modern techniques such as surface-enhanced infrared spectroscopy as a steady-sta...
