Green Synthesis of Highly Luminescent Carbon Quantum Dots from Lemon Juice
Journal of Nanotechnology, 2019 Highly luminescent carbon dots (C-dots) were synthesized by the one-pot simple hydrothermal method directly from lemon juice using different temperatures, time, aging of precursors, and diluted solvents to control the luminescence of C‐dots. The obtained

UVB-311 nm phototherapy and NAD(+)/NADH metabolism in keratinocytes in patients with psoriasis
Przegląd Dermatologiczny, 2019 Narrow band (311 nm) UVB phototherapy is established treatment for psoriasis. DNA is a target for UVB via formation of cyclobutane pyrimidine dimers, which trigger loss of dendritic cells and macrophages, and inhibit CD4+ and CD8+ T cells.

Calibration of ultraviolet, mid-infrared and radio star formation rate indicators [PDF]
, 2017 We present calibrations for star formation rate indicators in the ultraviolet, mid-infrared and radio continuum bands, including one of the first direct calibrations of 150 MHz as a star formation rate indicator. Our calibrations utilize 66 nearby star forming galaxies with Balmer decrement corrected H-alpha luminosities, which span 5 orders of ...

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions
Advanced Functional Materials, EarlyView.A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

Carbon and Oxygen Galactic Gradients: Observational Values from HII Region Recombination Lines [PDF]
Astrophys.J. 618 (2004) L95-L98, 2004 We present results of deep echelle spectrophotometry of eight Galactic HII regions located at Galactocentric distances between 6.3 and 10.4 kpc. The data have been taken with the Very Large Telescope (VLT) Ultraviolet Echelle Spectrograph (UVES) in the 3100 to 10360 A range.
