Using room temperature Phosphorescence of Gold(I) complexes for PAHs sensing
The synthesis of two new phosphane-gold(I)-napthalimide complexes has been performed and characterized. The compounds present luminescent properties with denoted room temperature phosphorescence (RTP) induced by the proximity ...
Manipulation of competing ferromagnetic and antiferromagnetic domains in exchange biased nanostructures
Using photoemission electron microscopy combined with x-ray magnetic circular dichroism we show that a progressive spatial confinement of a ferromagnet (FM), either through thickness variation or laterally via patterning, ...
Comparative of machine learning classification strategies for electron energy loss spectroscopy: Support vector machines and artificial neural networks
Machine Learning (ML) strategies applied to Scanning and conventional Transmission Electron Microscopy have become a valuable tool for analyzing the large volumes of data generated by various S/TEM techniques. In this work, ...
Highly Specific and Wide Range NO2 sensor with color readout
We present a simple and inexpensive method to implement a Griess-Saltzman-type reaction that combines the advantages of the liquid phase method (high specificity and fast response time) with the benefits of a solid ...
The combined use of gold nanoparticles and infrared radiation enables cytosolic protein delivery
Cytosolic protein delivery remains elusive. The inability of most proteins to cross the cellular membrane is a huge hurdle. Here we explore the unique photothermal properties of gold nanorods (AuNRs) to trigger cytosolic ...
Utilizing biomass-based graphene oxide-polyaniline-Ag electrodes in microbial fuel cells to boost energy generation and heavy metal removal
Although regarded as environmentally stable, bioelectrochemical fuel cells or, microbial fuel cells (MFCs) continue to face challenges with sustaining electron transport. In response, we examined the performance of two ...
Diabetic Retinopathy and Ocular Melanoma: How far we are?
Diabetic retinopathy causes vascular damage to retinal neurons, presenting characteristics of chronic inflammation. The development of new therapies capable of combating vision loss involves knowledge of inflammatory retinal ...
Novel strategies against cancer: dexibuprofen loaded nanostructured lipid carriers
The aim of this work was to design innovative nanostructured lipid carriers (NLCs) for the delivery of dexibuprofen (DXI) as an antiproliferative therapy against tumoral processes, and overcome its side effects. DXI-NLC ...

The Activity Report of IN2UB for the year 2021. The members of the IN2UB community have good reasons to be proud of their contribution in giving shape to this report. Following the difficulties associated to the aftermath ...
Integrated Strategy toward Self-Powering and Selectivity Tuning of Semiconductor Gas Sensors
Inorganic conductometric gas sensors struggle to overcome limitations in high power consumption and poor selectivi-ty. Herein, recent advances in developing self-powered gas sensors with tunable selectivity are introduced. ...
Fall-back time for photo-ionized Cs atoms attached to superfluid He-4 nanodroplets
We have studied the dynamic evolution of a Cs atom photo-excited from 6s to 6p and 7s states on a helium droplet using time-dependent 4He-DFT simulations. Depending on the excited electronic state, the Cs impurity remains ...
pi-Donor/pi-Acceptor Interactions for the Encapsulation of Neurotransmitters on Functionalized Polysilicon-Based Microparticles
Bipyridinium salts, commonly known as viologens, are π-acceptor molecules that strongly interact with π-donor compounds, such as porphyrins or amino acids, leading their self-assembling. These properties have promoted us ...
Erratum: Rotating He-3 droplets [J. Chem. Phys. 152, 184111 (2020)]
Due to an error in the assigned value to the k = 0 component of the FFT of the screened Lennard-Jones potential, the DFT results shown in this article1 are affected to some extent. Here Fig. 1 presents the correct appearance ...
Novel strategies enhancing endodontic disinfection: antibacterial biodegradable calcium hydroxide nanoparticles in an ex vivo model
<span style="color:rgb( 33 , 33 , 33 )">Due to the high failure rates associated to endodontic disinfection, this study aimed to investigate the antibacterial properties of poly(lactic-co-glycolic acid) (PLGA) nanoparticles ...
On-the-Fly Synthesis of Freestanding Spin-Crossover Architectures With Tunable Magnetic Properties
Spin-crossover (SCO) molecular-based switches have shown promise across a range of applications since their discovery, including sensing, information storage, actuators, and displays. Yet limited processability remains a ...
Synergistic antipseudomonal effects of synthetic peptide AMP38 and carbapenems
The aim was to explore the antimicrobial activity of a synthetic peptide (AMP38) and its synergy with imipenem against imipenem-resistant Pseudomonas aeruginosa. The main mechanism of imipenem resistance is the loss or ...
Medium-pressure hydrogen storage on activated carbon derived from biomass conversion
This study presents the utilization of activated carbons (ACs) derived from Polypodium vulgare, a commonly available feedstock, for effective medium-pressure H2 storage. For the ACs preparation, biomass was treated with ...
Antimalarial Activity of Orally Administered Curcumin Incorporated in Eudragit((R))-Containing Liposomes
