Synergistic Interaction between Anionic and Nonionic Surfactant: Application of the Mixed Micelles Templates for the Synthesis of Silver Nanoparticles

open access: yesInternational Journal of Electrochemical Science, 2016
Interaction between the anionic and nonionic surfactant at bulk and air/water interface has been studied. The synergistic interaction between surfactants was found in both in bulk solution as well as the interface.

Possibility of lifetime measurement in a flowing medium with phase fluorometry

open access: yes, 1991
The possibility of lifetime measurement in a flowing medium with phase fluorometry is investigated theoretically. A 3-D time dependent partial differential equation of the number density of atoms (or molecules) in the upper level of the fluorescence ...

Evaluation of Chlorophyll-a and POC MODIS Aqua Products in the Southern Ocean

open access: yesRemote Sensing, 2019
The Southern Ocean (SO) is highly sensitive to climate change. Therefore, an accurate estimate of phytoplankton biomass is key to being able to predict the climate trajectory of the 21st century.

On-Target Deposition from Two Engine-Powered Sprayers in Medium-Foliage-Density Citrus Canopies

open access: yesAgronomy
Spray penetration into citrus canopies is critical for adequate coverage and deposition to ensure effective pest control. However, mismatch of air assistance to target canopy characteristics can lead to unintended spraying losses through overpenetration.

Active site voltage clamp fluorometry of the sodium glucose cotransporter hSGLT1

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2017
Significance Site-directed fluorometry was used to understand conformational changes of the Na+/glucose symporter. SGLT1 functions by a mechanism where the substrate-binding site alternates between the two faces of the membrane, but little is known about

Influence of seeding rates on the quantum yield of photosynthesis for some field crops

open access: yesТруды по прикладной ботанике, генетике и селекции
Background. Photosynthesis is one of the most important physiological processes in plants, affecting the productivity of agrocenoses. Creating conditions for crops to absorb and convert solar energy as effectively as possible can be a means of increasing

Efflux-Mediated Resistance in Enterobacteriaceae: Recent Advances and Ongoing Challenges to Inhibit Bacterial Efflux Pumps

open access: yesAntibiotics
Efflux is one of the key mechanisms used by Gram-negative bacteria to reduce internal antibiotic concentrations. These active transport systems recognize and expel a wide range of toxic molecules, including antibiotics, thereby contributing to reduced ...

Automation and Active Learning for the Multi‐Objective Optimization of Antibody Formulations

open access: yesAdvanced Science, EarlyView.
Successful antibody formulation necessitates balancing factors such as thermal stability, colloidal stability, and viscosity across a vast excipient design space. This work integrates robotic liquid handling, high‐throughput biophysical characterization, and multi‐objective Bayesian optimization in an iterative closed‐loop Design‐Build‐Test‐Learn cycle.
