Effect of Solvent Quality on Laminar Slip Flow Penetration of Poly(N-isopropylacrylamide) Films with an Exploration of the Mass Transport Mechanism.

Good solvent quality significantly increases slip flow penetration in poly(N-isopropylacrylamide) films, with linear Fickian diffusion being the dominant mechanism for mass transport of small molecules.

Transfer and trapping of excitation energy in photosystem II as studied by chlorophyll alpha 2 fluorescence quenching by dinitrobenzene and carotenoid triplet. The matrix model.

The matrix model suggests that photosystem II in Chlorella vulgaris is a matrix of chlorophyll molecules in which reaction centers are embedded, with high rate constants for quenching by dinitrobenzene and carotenoid triplet.

Solution studies on heme proteins: subunit structure, dissociation, and unfolding of Lumbricus terrestris hemoglobin by the ureas.

Urea and alkylureas dissociate Lumbricus terrestris hemoglobin into various structures, suggesting hydrophobic interactions play a role in maintaining the folded conformation of subunits.

The effects of salts on the subunit structure and dissociation of Lumbricus terrestris hemoglobin.

Neutral salts are more effective dissociating agents for Lumbricus terrestris hemoglobin, suggesting polar and ionic interactions are more important for protein maintenance than hydrophobic interactions.

The Role of Cations in the Photoinduced Electron Transport of Cyanobacteria

Cations play a crucial role in photoinduced electron transport in cyanobacteria, influencing the partial processes of photosynthesis and influencing the regulation of electrolytes in plants.

A critical review of the literature on nitrobenzene toxicity.

Nitrobenzene exposure is associated with methemoglobinemia, histopathologic changes in various organ systems, and liver lesions, but its carcinogenic, teratogenic, and reproductive effects remain unclear.
