Mechanisms of femtosecond laser-induced refractive index modification of poly(methyl methacrylate) [PDF]
, 2010 The mechanisms of refractive index change in poly(methyl methacrylate) by frequency doubled femtosecond laser pulses are investigated. It is demonstrated that positive refractive index modificaton can be caused by a combination of depolymerization and ...

Dysregulation of microtubule stability impairs morphofunctional connectivity in primary neuronal networks [PDF]
, 2017 Functionally related neurons assemble into connected networks that process and transmit electrochemical information. To do this in a coordinated manner, the number and strength of synaptic connections is tightly regulated.

Membranes, 2019 One way of valorizing the lignin waste stream from the pulp and paper industries is depolymerizing it into low-molecular-mass compounds (LMMC). However, a common problem in the depolymerization of Kraft lignin is the low yields of small aromatic ...

A pharmacological cocktail for arresting actin dynamics in living cells. [PDF]
, 2011 The actin cytoskeleton is regulated by factors that influence polymer assembly, disassembly, and network rearrangement. Drugs that inhibit these events have been used to test the role of actin dynamics in a wide range of cellular processes.

Recent Advances in Mechanochemical Pretreatment of Lignocellulosic Biomass
Energies, 2022 Biorefineries are industrial facilities where biomass is converted into chemicals, fuels and energy. The use of lignocellulose as raw material implies the development of pretreatments to reduce its recalcitrant character prior to the processes that lead ...

Kinetics and thermodynamics of first-order Markov chain copolymerization
, 2014 We report a theoretical study of stochastic processes modeling the growth of first-order Markov copolymers, as well as the reversed reaction of depolymerization. These processes are ruled by kinetic equations describing both the attachment and detachment

Growth and dissolution of macromolecular Markov chains
, 2016 The kinetics and thermodynamics of free living copolymerization are studied for processes with rates depending on k monomeric units of the macromolecular chain behind the unit that is attached or detached. In this case, the sequence of monomeric units in

A bacteriophage tubulin harnesses dynamic instability to center DNA in infected cells. [PDF]
, 2014 Dynamic instability, polarity, and spatiotemporal organization are hallmarks of the microtubule cytoskeleton that allow formation of complex structures such as the eukaryotic spindle. No similar structure has been identified in prokaryotes.
