The carriers of the diffuse interstellar bands (DIBs) are still largely unknown although polycyclic aromatic hydrocarbons, carbon chains, and fullerenes are likely candidates. A recent analysis of the properties of n-acenes of general formula C4n+2H2n+4 suggested that these could be potential carriers of some DIBs. Dehydrogenation reactions of n-acenes after absorption of an interstellar UV photon may result in dehydroacenes.

Understanding low-temperature combustion mechanisms of hydrocarbons is aided by isomer-resolved experiments and chemical kinetics modeling of complex species. Alkyl-substituted cyclic ethers are intermediates formed during low-temperature oxidation and are derived from unimolecular reactions of hydroperoxyalkyl radicals (Q̇OOH). To understand the combustion of these cyclic ethers and differences in stereochemistry, comparison of chemical kinetics modeling with species profiles produced from the competing network reactions are required.

Carbon’s diverse bonding configurations give rise to an exceptional range of nanostructures. These discoveries have inspired intensive research into carbon nanomaterials and their self-organization into functional architectures. This review traces the evolution of carbon nanomaterials and focuses on three representative structural units: fullerenes, carbon dots, and carbon nanotubes.

The use of gold nanoparticles (AuNPs) for cancer theranostics—combining diagnosis and therapy into a single system—has been one of the most promising nanoplatforms. Their tunable optical and surface features make it possible to transform light into heat for photothermal treatment, generate reactive oxygen species for photodynamic therapy, and carry chemotherapeutics or antibodies for immunotherapy.

Membrane proteins are ideal drug targets due to their ubiquitous responsibilities in cellular signaling, substrate and ion transport, and ease of access due to their location in the cell. Membrane proteins are also notoriously difficult to study due to their hydrophobicity and flexible sections. Surface plasmon resonance (SPR) is an optical method that has offered multiple methodologies to study membrane proteins, including immobilizing these proteins by using detergents, histidine tagged receptors, and nanodiscs.

Scintillators are widely known and used in various fields such as radiation detection, industry inspection, and specifically for their applications in the medical imaging field. Current scintillators such as Cs:TI possess promising features but have several drawbacks: the use of toxic elements, limited stability, time-consuming preparation processes, etc. With these issues, the advancement of X-ray imaging technologies demands scintillators that are not only highly efficient but also stable, flexible, and environmentally benign.

Surface-active organics (surfactants) have previously been measured in atmospheric aerosol particles to quantify their ability to reduce particle surface tension and influence the indirect effects of aerosol particles on the climate. However, surfactants have not been extensively studied in biomass burning aerosols (BBA), which could result in an underestimation when quantifying the contribution of surface tension on aerosol-cloud interactions.

Nosocomial bacterial infections are a prevalent issue due to pathogenic bacteria having easier access to invade the bloodstream.

Nowadays, ion mobility is getting more and more popular due to its ability to add an additional degree of separation when coupled with traditional techniques like liquid or gas chromatography along with providing key information for a molecule’s collision crosssection (CCS). CCS is a measurement of a molecule’s effective area when it is allowed to collide with a neutral gas such as Helium or Nitrogen under the influence of an electrical current.
