Two-micron spectrophotometry of the galaxy NGC 253 [PDF]

, 1979
A very strong Brackett-gamma hydrogen emission line, and the 2.3 micron CO stellar absorption feature were measured in NGC 253. The presence and strength of the CO feature indicates that late type giant stars produce most of the 2.2 micron continuum ...

Recent Progress on Photoelectrochemical Organic Upgrading: A Review from Direct and Indirect Charge Transfer Pathway

Advanced Energy Materials, EarlyView.
Photoelectrochemical (PEC) organic upgrading at the anode, coupled with hydrogen evolution at the cathode, presents a promising strategy for enhancing solar energy utilization while simultaneously generating value‐added chemicals. An overview of directional photoanodic conversion of organic substrates is presented, distinctively with an eye to the ...

Spin Matters: A Multidisciplinary Roadmap to Understanding Spin Effects in Oxygen Evolution Reaction During Water Electrolysis

Advanced Energy Materials, EarlyView.
This roadmap offers a forward‐looking perspective on spin enhancement in the oxygen evolution reaction. It highlights how combining systematic experiments, advanced computational modeling, and novel magnetic, chiral, or hybrid materials can deepen the understanding of spin‐dependent catalytic mechanisms.

In Situ High‐Resolution Imaging of Live Treponema pallidum Using Catalyst‐Free Bioorthogonal Strategy

Aggregate, EarlyView.
Schematic illustration of labeling live Treponema pallidum using an activated alkyne‐modified AIE chromophore via catalyst‐free bioorthogonal reaction. ABSTRACT Treponema pallidum (T. pallidum) causes syphilis, a sexually transmitted disease that leads to multi‐organ complications and even death. The lack of technology for tracing live T.

Engineering Lanthanide Metal‐Organic Framework Nuclease Nanozymes: Unveiling Affinity‐Driven DNA Hydrolysis

Aggregate, EarlyView.
Affinity‐engineered lanthanide MOFs overturn the Lewis acidity paradigm: DNA hydrolysis efficiency rises with atomic number despite weaker binding. Yb‐BDC achieves record DNA‐cleaving activity yet low BNPP activity, revealing a critical binding–release cycle.

Naturally occurring epoxy acids: ii. detection and measurement of long-chain epoxy acids by near infrared spectrophotometry*†

Journal of Lipid Research, 1961
A new method for the detection and estimation of long-chain epoxy acids in seed oils is described. It depends on the measurement of increased absorption at 2.795 μ in the near infrared spectrum caused by chlorohydrins produced from epoxides by treatment ...
