Preserving Proton Resolution Under Cryogenic Dynamic Nuclear Polarization for Biomolecular Solid‐State NMR

open access: yesAngewandte Chemie, EarlyView.
High‐resolution proton detection is preserved under cryogenic dynamic nuclear polarization (DNP) by combining fast MAS, extensive deuteration and selective methyl protonation. This strategy enables proton‐detected structural studies of biomolecular solids with enhanced sensitivity under DNP conditions.

Revealing Hidden Raman Signatures Through Attention‐Based Spectral Unmixing

open access: yesAdvanced Intelligent Systems, EarlyView.
Weak Raman signatures are recovered from background‐dominated spectra using a transformer‐based, reference‐free spectral unmixing AI framework. Self‐attention reconstructs substrate contribution directly from mixed data, enabling reliable extraction of previously inaccessible vibrational features.

The Magic Project: large scale geohazard mapping of the Italian continental margins

open access: yes, 2009
The Italian continental margins display intense tectonic activity reflecting their recent origin and the complex geodynamic setting. In addition to tectonic activity, sea level and supply fluctuation (related to Quaternary climate changes) greatly ...

Short Sb···Sb Contacts in Polymorphic Tris(p‐Tolyl)Antimony: A Hallmark of Organoantimony(III) Solid‐State Chemistry?

open access: yesAngewandte Chemie, EarlyView.
Discovery of polymorphism in solid tris(p‐tolyl)antimony(III) highlighted short, direct antimony‐antimony contacts, with interatomic separation shorter than the sum of the van der Waals radii, and calculated interaction energy of ca. 26 kJ mol−1 that includes a significant dispersion component.

Transitioning to nonpunitive school policies for addressing student substance use: Qualitative interviews with key school administrators

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Recent policy change in Massachusetts encourages schools to limit their use of exclusionary discipline to “extraordinary circumstances,” but little work has explored the opportunities and challenges of transitioning to nonpunitive practices after student substance use infractions in schools.

Single‐Atom Control of Aromaticity and Excited‐State Dynamics in Endohedral Zirconium–Antimony Zintl Clusters

open access: yesAngewandte Chemie, EarlyView.
Single‐atom growth from [Zr@Sb12]2− to [Zr@Sb13]3− disrupts the closed‐shell S2P6 superatomic configuration and markedly attenuates three‐dimensional (3D) aromaticity. Ultrafast spectroscopy further links stronger spherical aromaticity to slower excited‐state relaxation, establishing an atom‐resolved structure‐aromaticity‐dynamics relationship ...

Juego de equilibrios

open access: yesDearq, 2012
To undertake large-scale projects requires organising a team that is very large in size. To aide this kind of team organisation ICT, 3D modelling, and File Organisation programmes can be of great use.

Phase II Study of Posttransplant Cyclophosphamide‐Based Graft‐Versus‐Host Disease Prophylaxis After HLA‐Mismatched Unrelated Donor Reduced Intensity Transplantation: Results From the ACCESS Trial Expansion Cohort

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Posttransplant cyclophosphamide (PTCy) to prevent graft‐versus‐host disease (GVHD) improves outcomes in recipients of HLA mismatched unrelated donor (MMUD) allogeneic hematopoietic cell transplantation (allo HCT). Outcomes of MMUD HCT using PTCy in patients requiring reduced intensity or non‐myeloablative conditioning (RIC/NMA) are not well ...

Semiconducting Covalent Organic Frameworks Based on Spin‐Delocalized Trioxotriangulene Neutral Radicals

open access: yesAngewandte Chemie, EarlyView.
Imine‐linked 2D covalent organic frameworks incorporating delocalized trioxotriangulene (TOT) neutral radicals were synthesized through complementary routes. Direct incorporation of an amine‐functionalized TOT radical yields a highly crystalline, porous framework (TOT‐COF‐H) with intrinsic semiconducting behavior (σRT = 1.2 × 10−4 S cm−1) and a narrow ...
