Highly Adjustable Three-Dimensional Hollow Pt(Au)Cu Nanonetwork Structures as Enhancing Electrocatalysts for Alcohol Oxidation Reaction

Pt-based nanomaterials are proven as one of the most efficient catalysts for direct alcohol fuel cells. However, it is a challenge to construct Pt-based catalysts with high catalytic activity and less...

Characterization of Staphylococci and Streptococci Isolated from Milk of Bovides with Mastitis in Egypt

The aim of this study was to characterize staphylococci and streptococci in milk from Egyptian bovides. In total, 50 milk samples were collected from localities in the Nile Delta region of Egypt. Isolates...

Imaging the Invisible – Bioorthogonal Raman Probes for Imaging of Cells and Tissues

A revolutionary avenue for vibrational imaging with super-multiplexing capability can be seen in the recent development of Raman-active bioortogonal tags or labels. These tags and isotopic labels represent...

Hybrid Nanomaterials of Biomolecule Corona Coated Magnetic Nanoparticles and their Interaction with Biological Systems

High performance fiber-Fabry-Perot resonator for quantum optics applications

Quantum optics experiments frequently require the separation of single-photon-level signals from strong classical fields. In circumstances in which the signals are spectrally close, and one cannot make...

Strawberry-like SiO2/Ag nanocomposites immersed filter paper as SERS substrate for acrylamide detection

In this work, based on the strawberry-like SiO2/Ag nanocomposites (SANC) immersed filter paper, a newly surface-enhanced Raman scattering (SERS) substrate was constructed for the detection of acrylamide...

Deep Learning for ‘Artefact’ Removal in Infrared Spectroscopy

It has been well recognized that infrared spectra of microscopically heterogeneous media do not merely reflect the absorption of the sample but are influenced also by geometric factors and the wave nature...

Microwave-Assisted Synthesis of Core–Shell Nanoparticles—Insights into the Growth of Different Geometries

Microwave irradiation is utilized for the rapid synthesis of gold–silver core–shell bimetallic nanoparticles (NPs) in a two-step process. A strategy of establishing a bilayer organic barrier around...

Metastable atomic layer deposition: 3D self-assembly towards ultra-dark materials

Black body materials are promising candidates to meet future energy demands, as they are able to harvest energy from the total bandwidth of solar radiation. Here, we report on high-absorption near-blackbody-like...

Investigating origins of FLIm contrast in atherosclerotic lesions using combined FLIm-Raman Spectroscopy

Background: Fluorescence lifetime imaging (FLIm) is a spectroscopic imaging technique able to characterize the composition of luminal surface of arterial vessels. Studies of human coronary samples demonstrated...
