Large nonlinear absorption in single aggregate of silver nanoparticles observed with z-scan imaging technique

open access: yesAIP Advances, 2021
Although nonlinear optical spectroscopy of nanostructures, nanomaterials, and nanomedicines has been widely used to observe and study the nature of nonlinear optical (NLO) phenomena, the field has to improve for the single nanostructure system.

Dynamics of Conformal Maps for a Class of Non-Laplacian Growth Phenomena

open access: yes, 2003
Time-dependent conformal maps are used to model a class of growth phenomena limited by coupled non-Laplacian transport processes, such as nonlinear diffusion, advection, and electro-migration.

Increasing temperature of cooling granular gases

open access: yesNature Communications, 2018
Granular gases—dilute systems composed of dissipatively colliding particles—exhibit anomalous dynamics and numerous surprising phenomena. Here, Brilliantov et al.

Modelling and Simulation of a Batch Poly(Vinyl Chloride) Reactor

open access: yesChemical Engineering Transactions, 2013
A population balance model for batch suspension polymerization of vinyl chloride is presented. Break up into two equal volumes of droplets, binary aggregation and random mass exchanges between the colliding droplets are assumed, while the kinetic data of

Synchronization as Aggregation: Cluster Kinetics of Pulse-Coupled Oscillators

open access: yes, 2015
We consider models of identical pulse-coupled oscillators with global interactions. Previous work showed that under certain conditions such systems always end up in sync, but did not quantify how small clusters of synchronized oscillators progressively ...

Joint perceptual decision-making: a case study in explanatory pluralism. [PDF]

open access: yes, 2014
Traditionally different approaches to the study of cognition have been viewed as competing explanatory frameworks. An alternative view, explanatory pluralism, regards different approaches to the study of cognition as complementary ways of studying the ...

Restoring autophagic function: a case for type 2 diabetes mellitus drug repurposing in Parkinson’s disease

open access: yesFrontiers in Neuroscience, 2023
Parkinson’s disease (PD) is a predominantly idiopathic pathological condition characterized by protein aggregation phenomena, whose main component is alpha-synuclein. Although the main risk factor is ageing, numerous evidence points to the role of type 2

An investigation on platelet transport during thrombus formation at micro-scale stenosis. [PDF]

open access: yesPLoS ONE, 2013
This paper reports on an investigation of mass transport of blood cells at micro-scale stenosis where local strain-rate micro-gradients trigger platelet aggregation.

Palladium-Catalyzed Direct Mono- and Diarylation of Diphenydithienylethenes: A Useful Method for Enhancing Fluorescence Intensity and Aggregation-Induced Emission

open access: yesMolbank, 2021
In this study we report efficient method for the syntheses of mono- and diarylated diphenyldithienylethene (DPDTE) via a palladium-catalyzed C–H arylation reaction.

Molecular mechanisms driving the microgels behaviour: a Raman spectroscopy and Dynamic Light Scattering study

open access: yes, 2019
Responsive microgels based on poly(N-isopropylacrylamide) (PNIPAM) exhibit peculiar behaviours due to the competition between the hydrophilic and hydrophobic interactions of the constituent networks. The interpenetration of poly-acrilic acid (PAAc), a pH-
