Sensors, 2018 We present the mixing and merging of two reactive droplets on top of an open surface. A mobile droplet (1.0 M HCl solution + iron oxide particles) is magnetically-actuated to merge with a sessile droplet (1.0 M NaOH + phenolphthalein).

Acid-base Properties of Modified Peat Fulvic Acid [PDF]
, 2014 The Effect of Mechanochemical modification on the acid-base properties of fulvic acid peat has been studied. It is found that modifying reagent CS(NH[2])[2] increases the amount of aromatic fragments and has no effect on the depletion of functional ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The pH and ionic composition of the sub-embryonic fluid of the Japanese quail (Coturnix c. japonica) [PDF]
, 2005 The current theory of acid-base chemistry regards [H+] as a dependent variable: changes in pH of a fluid can only occur by alteration of strong ion concentrations ([Na+], [K+], [Cl-]).

A Theoretical and Experimental Study on the Lewis Acid−Base Adducts (P4E3)·(BX3) (E = S, Se; X = Br, I) and (P4Se3)·(NbCl5) [PDF]
, 2001 The Lewis acid−base adducts (P4E3)·(BX3) (E = S, Se; X = Br, I) and (P4Se3)·(NbCl5) have been prepared and characterized by Raman, IR, and solid-state 31P MAS NMR spectroscopy. Hybrid density functional calculations (B3LYP) have been carried out for both

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Mechanistic Links Between the Sedimentary Redox Cycle and Marine Acid-Base Chemistry [PDF]
, 2019 The redox state of Earth's surface is controlled on geological timescales by the flow of electrons through the sedimentary rock cycle, mediated largely by the weathering and burial of C‐S‐Fe phases. These processes buffer atmospheric pO₂.

Substrate-Assisted Catalysis Unifies Two Families of Chitinolytic Enzymes [PDF]
, 1997 Hen egg-white lysozyme has long been the paradigm for enzymatic glycosyl hydrolysis with retention of configuration, with a protonated carboxylic acid and a deprotonated carboxylate participating in general acid-base catalysis.
