Direct conversion of aromatic amides into crystalline covalent triazine frameworks by a condensation mechanism

open access: yesCell Reports Physical Science, 2021
Summary: Multiple studies have recently been conducted to develop well-ordered covalent triazine-based frameworks (CTFs). To date, few studies have demonstrated CTFs with high crystallinity using novel synthesis strategies and different building blocks ...

Boson Peak and Superstructural Groups in Na2O-B2O3 Glasses

open access: yesAdvances in Condensed Matter Physics, 2018
Low-frequency Raman spectra of the sodium borate glasses with Na2O content ranging from 0 to 30 mol% were measured and analyzed from the point of view of their structure in the intermediate range order.

Topological Ordered Rings and Measures

open access: yesResults in Mathematics, 2023
AbstractGiven a ring endowed with a ring order, we provide sufficient conditions for the order topology induced by the ring order to become a ring topology (analogous results for module orders are consequently derived). Finally, the notions of Radon and regular measures are transported to the scope of module-valued measures through module orders ...

2,2′-(Hexane-1,6-diyl)diisoquinolinium tetrachloridozincate(II)

open access: yesActa Crystallographica Section E, 2009
The asymmetric unit of the title compound, (C24H26N2)[ZnCl4], consists of two 2,2′-(hexane-1,6-diyl)diisoquinolinium cations and two [ZnCl4]2− complex anions. The [ZnCl4]2− anions have a distorted tetrahedral geometry.

Preparation and Application of Metal Oxides/SBA-15 Mesoporous Composites as Catalysts for Selective Oxidation of benzyl alcohol

open access: yesInternational Journal of Electrochemical Science, 2022
In this project, SBA-15 with a mesoporous pore channel structure was synthesized by a hydrothermal method and its characterization by XRD, SEM and TEM proved that the mesoporous channels had highly ordered.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Cryo-EM structures of human p97 double hexamer capture potentiated ATPase-competent state

open access: yesCell Discovery, 2022
The conserved ATPase p97 (Cdc48 in yeast) and adaptors mediate diverse cellular processes through unfolding polyubiquitinated proteins and extracting them from macromolecular assemblies and membranes for disaggregation and degradation.

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.

Radial Level Planarity Testing and Embedding in Linear Time

open access: yesJournal of Graph Algorithms and Applications, 2005
A graph with an ordered k-partition of the vertices is radial level planar if there is a strictly outward drawing on k concentric levels without crossings.
