Multicolor and Attenuated Light Intensity Responses in Protein Hydrogels Arising from Photoregulated Crosslink Dynamics

open access: yesAngewandte Chemie International Edition, EarlyView.
A fully protein‐based hydrogel integrated two orthogonal photoreceptors to enable reversible manipulation of stiffness with red/far‐red light and irreversible gel‐sol transitions with green light. Unexpectedly, high‐intensity red light results in attenuated stiffening and dark‐adaptation, arising from increased crosslinking dynamics in the ...

Genomics of Urea Transport and Catabolism in Cyanobacteria: Biotechnological Implications

open access: yesFrontiers in Microbiology, 2019
Cyanobacteria are widely-diverse prokaryotes that colonize our planet. They use solar energy to assimilate huge amounts of atmospheric CO2 and produce a large part of the biomass and oxygen that sustain most life forms.

Tackling Multiple-Drug-Resistant Bacteria With Conventional and Complex Phytochemicals

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Emerging antibiotic resistance in bacteria endorses the failure of existing drugs with chronic illness, complicated treatment, and ever-increasing expenditures. Bacteria acquire the nature to adapt to starving conditions, abiotic stress, antibiotics, and

Mixotrophy in cyanobacteria

open access: yesCurrent Opinion in Microbiology
Cyanobacteria evolved the oxygenic photosynthesis to generate organic matter from CO2 and sunlight, and they were responsible for the production of oxygen in the Earth's atmosphere. This made them a model for photosynthetic organisms, since they are easier to study than higher plants.

A Comparison of Phycocyanins from Three Different Species of Cyanobacteria Employing Resonance-Enhanced Coherent Anti-Stokes Raman Spectroscopy [PDF]

open access: yes, 1993
Resonance-enhanced coherent anti-Stokes Raman spectra are recorded for monomers and trimers of phycocyanin from three different cyanobacteria: Westiellopsis prolifica, Mastigocladus laminosus and Spirulina platensis.

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.
