Copper nitride: a versatile semiconductor with great potential for next-generation photovoltaics
Copper nitride (Cu<sub>3</sub>N) has gained significant attention recently due to its potential in several scientific and technological applications. This study focuses on using Cu<sub>3</sub>N as a solar absorber in ...
Nature Inspired Manganese(III)-Calcium Complexes: Towards Synthetic Models for the WOC of PSII
For some time, the presence of high oxidation state Mn ions and Ca(II) in the active center of Photosystem II has been known. However, coordination complexes that combine both Mn(III) and Ca(II) have been difficult to ...
Atomic layer deposition of SnO2 and TiO2 on electrodeposited BiOI thin films for efficient light-driven peroxymonosulfate activationited BiOI thin films for efficient light-driven peroxymonosulfate activation
Light-driven peroxymonosulfate (PMS) activation is gaining traction as a green advanced oxidation strategy for degrading recalcitrant water pollutants; however, catalyst instability and sluggish charge separation still ...
Electronic transport in QD based structures: from basic parameters to opto-electronic device simulations
We present a theoretical model that explains the optoelectronic response of nanodevices based on large quantum dot (QD) arrays. The model is grounded on rate equations in the self-consistent field regime and it accurately ...
Unveiling the Complex Magnetization Reversal Process in 3D Nickel Nanowire Networks
Understanding the interactions among magnetic nanostructures is one of the key factors to predict and control the advanced functionalities of Three-Dimensional (3D) integrated magnetic nanostructures. In this work, we focus ...
Pitting of malaria parasites in microfluidic devices mimicking spleen interendothelial slits
The spleen is a hematopoietic organ that participates in cellular and humoral immunity. It also serves as a quality control mechanism for removing senescent and/or poorly deformable red blood cells (RBCs) from circulation. ...
Cytotoxicity of osmium(ii) and cycloosmated half-sandwich complexes from 1-pyrenyl-containing phosphane ligands
Five metal-arene complexes of formula [MX2(η6-p-cymene)(diR(1-pyrenyl)phosphane)] (M = Os or Ru, X = Cl or I, R = isopropyl or phenyl) and symbolized as MRX2 were synthesized and fully characterized, namely OsiPrCl2, ...
Study of Ni/CeO2-ZnO catalysts in the production of H2 from acetone steam reforming
This paper reports the study of new Ni/ZnO-based catalysts for hydrogen production from substoichiometric acetone steam reforming (ASR). The effect of CeO2 introduction is analyzed regarding the catalytic behavior and ...
Allosteric Spin Crossover Induced by Ligand-Based Molecular Alloying
he spin crossover (SCO) phenomenon represents a source of multistability at the molecular level, and dilution into a nonactive host was originally key to understand its cooperative nature and the parameters governing it ...
Detection of Protein Aggregation in Live Plasmodium Parasites.
The rapid evolution of resistance in the malaria parasite to every single drug developed against it calls for the urgent identification of new molecular targets. Using a stain specific for the detection of intracellular ...
Playing with the weakest supramolecular interactions in a 3D crystalline hexakis[60]fullerene induces control over hydrogenation selectivity
Weak forces can play an essential role in chemical reactions. Controlling such subtle forces inreorganization processes by applying thermal or chemical stimuli represents a novel synthetic strategyand one of the main targets ...
Superfluid helium droplet-mediated surface-deposition of neutral and charged silver atomic species.
Experimental and theoretical work has delivered evidence of the helium nanodroplet-mediated synthesis and soft-landing of metal nanoparticles, nanowires, clusters, and single atoms on solid sup- ports. Recent experimental ...
Electroforming of Si NCs/p-Si photovoltaic devices: Enhancement of the conversion efficiency through resistive switching
In this work, the relation between the photovoltaic and resistive switching (RS) properties of metal-oxide-semiconductor devices containing Si nanocrystal (Si NC) superlattices is investigated. A first approximation concludes ...
Dynamical shapes of droplets of cyclodextrin/surfactants solutions
We present a series of experiments with droplets of aqueous cyclodextrin-surfactant solutions, in which the volume is reduced after the equilibrium spherical shape is reached. The fnal shape of the drop after this perturbation ...
The dynamics of shapes of vesicle membranes with time dependent spontaneous curvature
We study the time evolution of the shape of a vesicle membrane under time-dependent spontaneous curvature by means of phase-field model. We introduce the variation in time of the spontaneous curvature via a second field ...
Spontaneous Hetero-attachment of Single-Component Colloidal Precursors for the Synthesis of Asymmetric Au−Ag2X (X = S, Se) Heterodimers
Finding simple, easily controlled, and flexible synthetic routes for the preparation of ternary and hybrid nanostructured semiconductors is always highly desirable, especially to fulfill the requirements for mass production ...
