Excitation Energy Transfer and Trapping in Higher Plant Photosystem II Complexes with Different Antenna Sizes [PDF]

open access: yes, 2011
700 cm(-1)) and a slow relaxation of the radical pair to an irreversible state (similar to 150 ps). Somewhat unexpectedly, we had to reduce the energy-transfer and charge-separation rates in complexes with decreasing size to obtain optimal fits.

Single and Double Knockouts of the Genes for Photosystem I Subunits G, K, and H of Arabidopsis [PDF]

open access: yes, 2002
Photosystem I (PSI) of higher plants contains 18 subunits. Using Arabidopsis En insertion lines, we have isolated knockout alleles of the genes psaG, psaH2, and psaK, which code for PSI-G, -H, and -K.

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Dynamics of photosynthetic complexes in the thylakoid membranes from higher plants

open access: yes, 2011
PhDPhotosynthetic machinery in higher plants is localised in the thylakoids enclosed in a chloroplast. To optimise and regulate the photosynthetic efficiency under different, rapidly changeable environmental conditions the dynamics of the thylakoid

Advances in Chitosan Nanoparticles: A Comprehensive Review of Properties, Synthesis, Characterization, Multidisciplinary Applications, and Future Perspectives

open access: yesJournal of Applied Polymer Science, EarlyView.
This review highlights the synthesis of chitosan nanoparticles from natural sources, the thorough characterization of them, and use of microscopic and spectroscopic methods. It emphasizes that it has some indispensable properties such as being non‐toxic, antimicrobial, and capable of controlled drug release.

Monitoring photosynthesis in individual cells of Synechocytis sp. PCC 6803 on a picosecond timescale

open access: yes, 2010
Picosecond fluorescence kinetics of wild-type (WT) and mutant cells of Synechocystis sp. PCC 6803, were studied at the ensemble level with a streak-camera and at the cell level using fluorescence-lifetime-imaging microscopy (FLIM).

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

open access: yesAdvanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Harnessing plant‐based platform for low‐cost cellulosic sugar recovery from bioenergy crops

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The price of pure cellulase enzyme for the recovery of fermentable cellulosic sugars is one of the major challenges that limit the commercialization of second‐generation biofuels and bio‐based products. This work shows a means to greatly reduce the cost of cellulases. The abundant capacity of plants to synthesize and hyperaccumulate transgenic

Cryo-electron microscopy structure of the intact photosynthetic light-harvesting antenna-reaction center complex from a green sulfur bacterium

open access: yes, 2023
The photosynthetic reaction center complex (RCC) of green sulfur bacteria (GSB) consists of the membrane-imbedded RC core and the peripheric energy transmitting proteins called Fenna-Matthews-Olson (FMO).

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

open access: yesBMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...
