Spike‐Embedded Nanocatalysts via Metal‐Directed Carbonization for Highly Efficient and Robust Semi‐Hydrogenation

open access: yesAdvanced Science, EarlyView.
A metal‐directed carbonization strategy transforms hierarchical organic microspheres into spiky carbon catalysts with Pd nanoparticles embedded at the tips. This approach resolves the activity‐stability trade‐off, achieving exceptional poison resistance in semi‐hydrogenations, offering a versatile, scalable platform for designing high‐performance ...

Superhyperfine interactions in Xe–NO2

open access: yesChemical Physics Letters, 1998
Abstract Microwave spectra of the 129 Xe and 131 Xe isotopes of Xe–NO 2 have been recorded using a Fourier transform microwave spectrometer. Intermolecular superhyperfine interactions were observed between the Xe nuclear magnetic moment and the unpaired electron on the NO 2 radical.

Development Of SCIAMACHY Operational ESA Level 2 Products Towards Version 5 And Beyond

open access: yes, 2009
Since the foundation of the SCIAMACHY Quality Working Group (SQWG) in a joint ESA-DLR-NIVR inter-agency effort in late 2006, the ESA operational Level 2 processor was significantly improved w.r.t. data quality and product range. During the last two years

Uptake of NO2 by plants grown at different salinity levels

open access: yes, 1980
It is demonstrated that the uptake of nitrogen dioxide (NO2) byPhaseolus vulgaris L. is decreased by the addition of sodium chloride (NaCl) to the root medium, as a result of increased diffusive resistance of the leaves.

Photocatalytic Synthesis of Pentafluorosulfanyl Ketones, Acetals, and BCP Motifs Utilizing SF6

open access: yesAdvanced Science, EarlyView.
A photocatalytic single electron reduction strategy is reported for the activation and valorization of sulfur hexafluoride (SF6), a potent greenhouse gas. Under mild conditions, SF6 is reduced to generate pentafluorosulfanyl (SF5) radicals, enabling direct access to pentafluorosulfanyl ketones, acetals, and BCP motifs.

Asymmetrically Fluorinated Phenyl 4‐biphenylcarboxylate Motifs as a Design Principle for Enantiotropic Ferroelectric Liquid Crystals

open access: yesAdvanced Science, EarlyView.
The effect of the structural arrangement of DIO and its analogs on ferroelectric phases is explored. Consequently, it is found that an asymmetrically fluorinated phenyl 4‐biphenylcaroboxylate skeleton is one of the favorable structural motifs for the emergence of enantiotropic ferroelectric liquid crystal phases.

Effects of NO2 and Nitrate on Sulfate Assimilation in Maize

open access: yes, 1995
Summary The effect of nitrogen dioxide (NO2) and nitrate on sulfate assimilation was studied in maize seedlings. The seedlings (Zea mays L. cv. LG 9) were grown on a N-free nutrient solution for 10 days and subsequently fumigated with 520 nLL-1 NO2 or ...

Divergent Adsorption-Dependent Luminescence of Amino- Functionalized Lanthanide Metal-Organic Frameworks for Highly Sensitive NO2 Sensors

open access: yes, 2020
A novel gas sensing mechanism exploiting the luminescence modulation upon NO2 adsorption is here demonstrated. Two isostructural lanthanide based-metal-organic frameworks are used including a recognition center (aminogroup) that provides high selectivity

Dual‐Substrate Synergistic Photocatalysis: Exogenous Reagent‐Free Co‐Removal of Phenol and Cr(VI) via Electron‐Donor‐Mediated Redox Coupling over Modified Carbon Nitride

open access: yesAdvanced Science, EarlyView.
An exogenous reagent‐free dual‐substrate strategy harnesses phenol as an intrinsic electron donor to drive synchronous phenol degradation and Cr(VI) reduction over modified carbon nitride. π–π stacking and hydrogen bonding direct electron transfer to the catalyst, enriching photogenerated electrons and accelerating Cr(VI) reduction 6.4‐fold. This waste‐
