Analytic formulas for frequency and size dependence of absorption and scattering efficiencies of astronomical polycyclic aromatic hydrocarbons

, 2012
In a series of two recent papers, the frequency and size distribution dependence of extinction spectra for astronomical silicate and graphite grains was analyzed by us in the context of MRN type interstellar dust models.

A comparison of PAH emission sampling methods (cyclone, impactor) in particulate and gaseous phase [PDF]

, 2018
Four different domestic heating boilers and four types of fuel (lignite, wet wood, wood pellets and mixed fuel) were tested, and the emissions of the particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs) were correlated. Dekati low-pressure

Engineering MnPt Bimetallic Nanozymes for Cascade Enzymatic Therapy and Enhanced Radio‐Immunotherapy

Advanced Science, EarlyView.
A CD44‐targeted MnPt bimetallic nanozyme (HD@MnO2) integrates multienzyme‐like activity with cGAS–STING activation to boost radio‐immunotherapy. Through cascade biocatalysis, it depletes glutathione, relieves hypoxia, and amplifies ROS, enhancing radiotherapy‐induced DNA damage and immunogenic cell death. The nanozyme promotes dendritic cell maturation

One‐Dimensional Polycyclic Aromatic Hydrocarbons Incorporating Multiple Dithiafulvene Units—Novel Multi‐Redox and Electrochromic Systems

Angewandte Chemie, EarlyView.
Planar polycyclic aromatic hydrocarbons (PAHs) incorporating three or four dithiafulvene (DTF) units were synthesized via Horner–Wadsworth–Emmons reactions to create large π‐conjugated redox‐active frameworks. These molecules display strong intermolecular associations and distinct odd–even redox behavior, enabling formation of mixed‐valence and radical‐

Urinary naphthalene and phenanthrene as biomarkers of occupational exposure to polycyclic aromatic hydrocarbons. [PDF]

, 2008
OBJECTIVES: The study investigated the utility of unmetabolised naphthalene (Nap) and phenanthrene (Phe) in urine as surrogates for exposures to mixtures of polycyclic aromatic hydrocarbons (PAHs).

Therapeutic Gases in Biomedicine: Updates on Nitric Oxide and Beyond

Advanced Science, EarlyView.
Therapeutic gases, including NO, CO, H2S, H2, CO2, O2, and Xe, play vital roles in cellular signaling and repair. This review highlights the emerging carriers and delivery systems that enable controlled, localized gas release for diagnostic and therapeutic applications.

Chiral Heptagon‐Embedded Double [6]Helicenes via Scholl Reaction

Angewandte Chemie, EarlyView.
One bond makes the difference–two chiral and twisted polycyclic aromatic hydrocarbons (PAHs) show different emission behavior. The more flexible one (top) shows a double emission with one having a large anti‐Stokes shift. The two peaks are assigned to different conformers of one and the same compound.

P-resonant control for the neutral point of three phase inverter [PDF]

, 2014
In this project, a Proportional resonant (PR) current controller is proposed to maintain a balanced neutral point for a three-phase four wire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional
