Longhorn beetles (Coleoptera: Cerambycidae) community composition around different boreal infrastructures

Author(s): Noor S; Despland E; Montoro Girona M; Work T;

Wood processing, mining, and recreational infrastructures facilitate the transport and establishment of woodboring insects. Longhorn beetles (Coleoptera: Cerambycidae) are woodborers that typically develop in stressed or dead trees and are inadvertently transported in wood products, creating opportunities for exotic species to invade and expand their rang ...

Scalable Synthesis of High-Quality Graphene Quantum Dots by Reductive Intercalation/Exfoliation of Coal

Author(s): Bepete G; Ratnayake G; Sanchez DE; Yu Z; Dimitrov E; Fest Carreno A; Oliveira MCD; Viana BC; Santos FEP; Terrones M;

Coal, historically a low-cost and abundant energy resource, is emerging as a promising carbon-rich precursor for advanced nanomaterials. In this work, we introduce a reductive intercalation strategy to synthesize reduced (electron-rich) graphene quantum dots (GQDs) directly from anthracite coal. ...

Non-invasive paper-based sensors containing rare-earth-doped nanoparticles for the detection of D-glucose

Author(s): López-Peña G; Ortiz-Mansilla E; Arranz A; Bogdan N; Manso-Silván M; Martín Rodríguez E;

Today, diabetes mellitus is one of the most common diseases that affects the population on a worldwide scale. Patients suffering from this disease are required to control their blood-glucose levels several times a day through invasive methods such as piercing their fingers. Our NaGdF4: 5% Er3+, 3% Nd3+ nanoparticles demonstrate a remarkable ability to det ...

Combining Pr3+-Doped Nanoradiosensitizers and Endogenous Protoporphyrin IX for X-ray-Mediated Photodynamic Therapy of Glioblastoma Cells

Author(s): Mandl GA; Vettier F; Tessitore G; Maurizio SL; Bietar K; Stochaj U; Capobianco JA;

Glioblastoma multiforme is an aggressive type of brain cancer with high recurrence rates due to the presence of radioresistant cells remaining after tumor resection. Here, we report the development of an X-ray-mediated photodynamic therapy (X-PDT) system using NaLuF4:25% Pr3+ radioluminescent nanoparticles in conjunction with protoporphyrin IX (PPIX), an ...

Upconversion Luminescence through Cooperative and Energy-Transfer Mechanisms in Yb3+ -Metal-Organic Frameworks

Author(s): Xie Y; Sun G; Mandl GA; Maurizio SL; Chen J; Capobianco JA; Sun L;

Lanthanide-doped metal-organic frameworks (Ln-MOFs) have versatile luminescence properties, however it is challenging to achieve lanthanide-based upconversion luminescence in these materials. Here, 1,3,5-benzenetricarboxylic acid (BTC) and trivalent Yb3+ ions were used to generate crystalline Yb-BTC MOF 1D-microrods with upconversion luminescence under ne ...

A Synthetic Biosensor for Detecting Putrescine in Beef Samples

Author(s): Selim AS; Perry JM; Nasr MA; Pimprikar JM; Shih SCC;

Biogenic amines (BAs) are toxicological risks present in many food products. Putrescine is the most common foodborne BA and is frequently used as a quality control marker. Currently, there is a lack of regulation concerning safe putrescine limits in food as well as outdated food handling practices leading to unnecessary putrescine intake. Conventional met ...

Energy migration control of multi-modal emissions in an Er3+ doped nanostructure toward information encryption and deep learning decoding

Author(s): Song Y; Lu M; Mandl GA; Xie Y; Sun G; Chen J; Liu X; Capobianco JA; Sun L;

Modulating the emission wavelengths of materials has always been a primary focus of fluorescence technology. Nanocrystals (NCs) doped with lanthanide ions with rich energy levels can produce a variety of emissions at different excitation wavelengths. However, the control of multi-modal emissions of these ions has remained a challenge. Herein, we present a ...

The Key Role of Intrinsic Lifetime Dynamics from Upconverting Nanosystems in Multiemission Particle Velocimetry

Author(s): Tessitore G; Maurizio SL; Sabri T; Skinner CD; Capobianco JA;

Evaluation of particle dynamics at the nano- and microscale poses a challenge to the development of novel velocimetry techniques. Established optical methods implement external or internal calibrations of the emission profiles by varying the particle velocity and are limited to specific experimental conditions. The proposed multiemission particle velocime ...
