Condensing the Cage: Novel Insights Into the Reaction Pathway of Isowurtzitane Cage Formation

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT In this contribution, we propose an alternative reaction pathway for the formation of isowurtzitane cages. These cage products are the basis for the synthesis of CL‐20, a highly prized energetic material and propellant. Isowurtzitane cages are typically formed under acid‐catalysed conditions via the condensation reaction between glyoxal and ...

Laser-Excited Emission from Glyoxal and Its Deuterated Derivatives

open access: yes, 1973
Emission spectra of glyoxal, glyoxal-d1, and glyoxal-d2 have been excited using the various lines of an argon ion laser. The bands have been assigned to 3 band systems, viz. the 1Au–1Ag and 3Au–1Ag (π*–n) systems of the trans molecule and the 1B1–1A1 (π*

Advancing Biomass Valorization via Electrocatalytic Oxidation: Design Principles, Emerging Challenges, and Future Perspectives

open access: yesSusMat, EarlyView.
This review categorizes substrates for electrocatalytic biomass valorization by carbon chain length into C2–C3 alcohols, C5–C7 cyclic compounds, and Cn biopolymers. It identifies four universal catalyst design principles: optimizing intermediate adsorption, engineering synergistic multi‐type active sites, accelerating active‐site formation, and ...

Efficient Synthesis of Dipyrazino[2,3-f; 2'3'-h]quinoxaline

open access: yesCHIMIA, 1987
The condensation of benzenehexamine (2) with the masked forms 3a or 3b of glyoxal leads to the title compound (4) in good yields; aqueous glyoxal is highly unsatisfactory.

Rethinking diabetic retinopathy: Homeostatic mechanisms for retinal clearance

open access: yesDiabetic Medicine, EarlyView.
In the healthy retina, balanced production and clearance of metabolic waste and fluid maintain retinal homeostasis and normal visual function. Diabetes disrupts this balance, increasing the accumulation of metabolic waste products, including advanced glycation end products (AGEs) and advanced lipoxidation end products (ALEs), while impairing waste and ...

Vegetation Dynamics and Atmospheric Glyoxal in Houston, Texas (2018–2022)

open access: yesAtmosphere
Twenty years of MODIS satellite data (2002–2022), TROPOMI glyoxal observations (2018–2022), and ground-based isoprene measurements were used to examine vegetation greenness (NDVI) and atmospheric glyoxal over Houston, Texas. Biogenically produced glyoxal

Films from Glyoxal-Crosslinked Spruce Galactoglucomannans Plasticized with Sorbitol [PDF]

open access: yes, 2012
Films were prepared from a renewable and biodegradable forest biorefinery product, spruce O-acetyl-galactoglucomannans (GGMs), crosslinked with glyoxal.

Amyloid β alters vascular CaV1.2 channel spatiotemporal properties

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Amyloid‐β1‐42 (Aβ1‐42) triggers a male‐specific signalling cascade influencing CaV1.2 spatiotemporal properties in cerebral vascular smooth muscle. The signalling pathway involves NADPH oxidase (NOX)‐derived reactive oxygen species (ROS) activation of protein kinase C (PKC). Aβ1‐42 can also activate protein kinase A (PKA).

Intracellular mechanosensation in intestinal smooth muscle: Piezo1 complexes amplify signalling beyond the surface

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Mechanosensation is not confined to the cell surface. In intestinal smooth muscle Piezo1 is predominantly intracellular (86%), where it forms a nanoscale (<40 nm) complex at the sarcoplasmic reticulum (SR)–plasma membrane junction. Within this sensor–amplifier–effector axis intra‐Piezo1 is the sensor that detects force at the SR,
