Infrared photometry and spectrophotometry of Titan [PDF]

open access: yes
The wide variation in infrared brightness temperature of Titan is explained in terms of a greenhouse effect. Radiometric observations in the infrared and microwave frequencies indicate an alternate hot atmospheric model. Methane, ammonia, hydrogen atoms,

High Resolution, Differential, Near-infrared Transmission Spectroscopy of GJ 1214b

open access: yes, 2011
The nearby star GJ 1214 hosts a planet intermediate in radius and mass between Earth and Neptune, resulting in some uncertainty as to its nature. We have observed this planet, GJ 1214b, during transit with the high-resolution, near-infrared NIRSPEC ...

Optimization and Characterization of Aspirin‐ and Ibuprofen‐Loaded Lipid‐Based Nanoparticle Synthesis for Antibacterial Activity and Cytotoxic Effect

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Lipid‐based nanoparticles (LNPs) are favored for drug delivery because of their low toxicity, high biocompatibility, ability to self‐assemble into nanoparticles, and ability to enhance drug bioavailability, thereby improving drug release modulation and pharmacokinetics.

Magnetic Pinecone Biochar‐Activated Peroxymonosulfate for Efficient Sulfamethoxazole Degradation: Performance, Mechanism, and Toxicity Analysis

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Development and Characterization of Cellulose Films Incorporating Vitamin A and E‐Loaded Liposomes

open access: yesJournal of Applied Polymer Science, EarlyView.
Liposome‐cellulose films deliver UV‐light shielding, wetting, and high rigidity for green tattoo aftercare. ABSTRACT This study introduces cellulose films enriched with vitamin A/E liposomes as sustainable, bioactive dressings for tattoo aftercare. Morphological analysis showed a smoother, more continuous microtexture than the neat cellulose films ...

Synthesis and Characterization of MnO2 nanoparticles mediated by Raphia hookeri seed

open access: yesJournal of Nigerian Society of Physical Sciences
In this study, managanese dioxide nanoparticles (MnO2-NP) was synthesized. Raphia hookeri seed was used as a bioreductant for the synthesis of MnO2-NPs. The biosynthesized MnO2-NPs was investigated for their reaction, structure and morphology.
