In this work we review all the available experimental neutron data for the (7)Li(p,n) reaction near threshold which is necessary to obtain an accurate source model for Monte Carlo simulations in Boron Neutron Capture Therapy. Scattered published experimental results such as cross sections, differential neutron yields and total yields were collected and analyzed, exploring the sensitivity of the fitting parameters to the different possible variables and deriving a consistent working set of parameters to evaluate the neutron source near threshold.

-Armchair graphene nanoribbons (nAGNRs) are promising components for next-generation nanoelectronics due to their controllable band gap, which depends on their width and edge structure. Using non-metal surfaces for fabricating nAGNRs gives access to reliable information on their electronic properties. We investigated the influence of light and iron adatoms on the debromination of 4,4''-dibromo--terphenyl precursors affording poly(-phenylene) (PPP as the narrowest GNR) wires through the Ullmann coupling reaction on a rutile TiO(110) surface, which we studied by scanning tunneling microscopy and X-ray photoemission spectroscopy.

In this research, the photophysical properties of metformin hydrochloride (MF-HCl) were studied using spectroscopic and molecular docking techniques. The interaction between metformin hydrochloride and caffeine is essential for understanding the pharmacokinetics of metformin, particularly in populations with high caffeine consumption. Metformin is a first-line medication for managing type 2 diabetes, while caffeine is a widely consumed dietary stimulant.

Reactive oxygen species (ROS)-mediated anticancer modalities, which disturb the redox balance of cancer cells through multi-pathway simulations, hold great promise for effective cancer management. Among these, cooperative physical and biochemical activation strategies have attracted increasing attention because of their spatiotemporal controllability, low toxicity, and high therapeutic efficacy. Herein, we demonstrate a nanogel complex as a multilevel ROS-producing system by integrating chloroperoxidase (CPO) into gold nanorod (AuNR)-based nanogels (ANGs) for cascade-amplifying photothermal-enzymatic synergistic tumor therapy.

Despite major progress in the investigation of boron cluster anions, direct experimental study of neutral boron clusters remains a significant challenge because of the difficulty in size selection. Here we report a size-specific study of the neutral B9 cluster using threshold photoionization with a tunable vacuum ultraviolet free electron laser. The ionization potential of B9 is measured to be 8.
