Infrared Spectrophotometry as a Means for Identification of Mosquitoes.

Experimental Biology and Medicine, 1953
SummaryCrude aqueous extracts of Culex molestus, Culex quinquefasciatus, and Aedes aegypti adult mosquitoes were identified by infrared spectrophotometry. The most important differences were the relative intensities of the peaks at about 6.95 and 7.2 μ, and the relative depth and shape of the broad band from about 8.6 to 10 μ.

Rational Molecular Engineering of Amidonaphthoquinone Cathodes: Precise Hydrogen Bond and Size Control for High‐Performance Lithium Organic Batteries

Advanced Science, EarlyView.
This work provides a novel molecular design strategy to develop three naphthoquinone‐derived cathodes (NQ1, NQ2, and NQ3) by linking one, two, and three amido‐naphthoquinone redox centers onto a benzene ring in a convenient way. Structure evolution to increased hydrogenbonds and molecular size enables high performance LOBs by joint solubility suppress ...

Synthesis of silver nanoparticles using plant extracts from Erythrina abyssinica aerial parts and assessment of their anti-bacterial and anti-oxidant activities

Results in Chemistry, 2022
In the present study, silver nanoparticles were synthesized using Erythrina abyssinica aerial parts as both reducing and capping agents. Three extracts were obtained from the plant using methanol, acetone and water.

Using Highly Functional Cr2O3 Interfacial Layer to Enhance the Electrical Performance of Au/InP Schottky Diodes

Advanced Electronic Materials, EarlyView.
The authors report on the significant impact of the spin‐coated Cr2O3 interface layer on the electrical properties and performance characteristics of Au/undoped‐InP (Au/InP) Schottky diodes (SD). The results and approach convincingly demonstrate the potential application of the Cr2O3 interfacial layer in delivering enhanced performance and contributing

Measurement of serum triglycerides by thin-layer chromatography and infrared spectrophotometry*

Journal of Lipid Research, 1963
A direct and nondestructive method for the quantitative determination of serum or plasma triglycerides has been developed. The lipid extract of 1 ml of serum is chromatographed on I-mm wet-thickness silicic acid layers prepared from a water–acetone ...

The use of infrared spectrophotometry for measuring body water spaces.

Clinical Chemistry, 1999
BACKGROUND The conventional method of measuring total body water by the deuterium isotope dilution method uses gas isotope ratio mass spectrometry (IRMS), which is both expensive and time-consuming.

Engineering A Multifunctional Nanoenzyme Platform for Synergistic Melanoma Therapy: Integrating Enzyme Activity, Immune Activation, and Low‐Temperature Photothermal Effects

Angewandte Chemie International Edition, Accepted Article.
Melanoma is characterized by rapid growth and high invasiveness, resulting in an exceptionally high malignancy and a significant propensity for metastasis. Current therapeutic modalities, such as chemotherapy and radiotherapy, exhibit limited efficacy due to severe side effects and immunosuppressive effects. Consequently, the development of precise and

An infrared-submillimeter study of star-forming regions selected by the ISOSS 170um survey

, 2008
Using the ISOPHOT Serendipity Survey (ISOSS) at 170um a sample of galactic star-forming regions exhibiting very cold dust temperatures (< 20 K) and high masses (> 100 M_sun) has been established.
