A unified electrostatic and cavitation model for first-principles molecular dynamics in solution
, 2005 The electrostatic continuum solvent model developed by Fattebert and Gygi is combined with a first-principles formulation of the cavitation energy based on a natural quantum-mechanical definition for the surface of a solute.

Microstructures in phase-inversion membranes. Part I. Formation of macrovoids [PDF]
, 1992 A new mechanism for the formation of macrovoids in phase-inversion membranes is proposed. It is based on the observed difference in type of demixing of a thin film of a polymer solution when immersed in a nonsolvent bath: delayed or instantaneous ...

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Parameters Affecting the Accelerated Solvent Extraction of Polymeric Samples
Analytical Chemistry, 1997 Accelerated solvent extraction (ASE) is applied for the extraction of monomers and oligomers from polymeric samples. Two polymers, nylon-6 and poly(1,4-butylene terephthalate), are selected as the model samples. The kinetics of mass transfer in ASE of polymeric samples are discussed.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Determining an Efficient Solvent Extraction Parameters for Re-Refining of Waste Lubricating Oils [PDF]
Mehran University Research Journal of Engineering and Technology, 2012 Re-refining of vehicle waste lubricating oil by solvent extraction is one of the efficient and cheapest methods. Three extracting solvents MEK (Methyl-Ethyl-Ketone), 1-butanol, 2-propanol were determined experimentally for their performance based on ...
