Synthesis of substituted triazole–pyrazole hybrids using triazenylpyrazole precursors

open access: yesBeilstein Journal of Organic Chemistry
A synthesis route to access triazole–pyrazole hybrids via triazenylpyrazoles was developed. Contrary to existing methods, this route allows the facile N-functionalization of the pyrazole before the attachment of the triazole unit via a copper-catalyzed ...

Site-Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids. [PDF]

open access: yesAngew Chem Int Ed Engl
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Photolysis of nickel hydroxy azide.

open access: yes, 2001
Photolysis of nickel hydroxy azide at 380 ºK is compared with that of nickel azide under similar considerations. Nickel azide sample was prepared by adapting the method of Brauer while nickel hydroxy azide was obtained by dehydrating the dihydrate of ...

Dual‐Organelle Secretome Conjugation and Organ‐Uptake Tracking (DuO‐SCOUT) Enables Deep and Sensitive Mapping of the Secreted Proteins

open access: yesAdvanced Science, EarlyView.
A novel dual‐organelle proximity labeling platform, DuO‐SCOUT, decodes the complex landscape of systemic organ‐organ communication by capturing both classical and unconventional secretomes. Application in metabolic models maps the adipose‐to‐brain secretory relay, identifying selective extra‐hypothalamic sites for adipose‐derived factors and expanding ...

Initiation and detonation in lead azide and silver azide at sub-millimeter geometries [PDF]

open access: yes, 2006
The process by which an energetic material is initiated and transitions from burning to detonation has been investigated and documented in the literature for many different materials.

Dual‐Targeting Biomimetic Nanozymes Loaded Microneedle Patch Promotes Scarless Wound Healing Through Anti‐Inflammatory and Anti‐Fibrotic Effects

open access: yesAdvanced Science, EarlyView.
This study developed a dual‐targeting biomimetic nanozyme hybrid system (Cu‐CeO2@ABs‐FTP) and integrated it with HAMA hydrogel to fabricate a microneedle patch (CAF@MN). The patch promotes fibroblast‐mediated wound repair, targets macrophages to induce M2 polarization, and targets myofibroblasts to exert anti‐fibrotic effects, thereby enabling rapid ...

Electric-Field-Induced Structural and Electronic Changes and Decomposition of Crystalline Lead Azide: A Computational Study

open access: yes, 2015
Periodic first-principles calculations have been performed to study the effects of electric field on the geometric and electronic structures and decomposition mechanism of crystalline lead azide (alpha-Pb(N-3)(2)).

SynNotch Receptors for Visualizing Immunoreceptor Force Transmission and Downstream Signaling In Vivo

open access: yesAdvanced Science, EarlyView.
A mechanically activated SynNotch reporter platform enables detection of force transmission through receptors as they mediate immune cell interactions. Targeting CD40 on B cells and TCR on T cells records force‐induced reporter activation across 2D coculture, 3D organoid, and implanted in mice, which also reveal force‐amplification of immune receptor ...

(Panel A) Absorption spectra of ligand-free and azide-bound ferric Cr-TrHb1-1.

open access: yes, 2015
The sodium azide concentration was 0.1 M. The arrow indicates the azide-dependent spectroscopic transition. (Panel B) Azide concentration dependence of the observed rate mobs for Cr-TrHb1-1 (●), Cr-TrHb1-2 (■) and Cr-TrHb1-4 (▲). Data were obtained at pH
