AF4-to-SAXS: expanded characterization of nanoparticles and proteins at the P12 BioSAXS beamline. [PDF]

J Synchrotron Radiat
By coupling asymmetrical‐flow field‐flow fractionation to small‐angle X‐ray scattering (AF4–SAXS), we enable precise, size‐resolved analysis of polydisperse samples. Our automated AF4–SAXS system at the EMBL P12 beamline streamlines workflows, making advanced characterization accessible to both novice and experienced users, with principles adaptable to

PLLA‐Based Block Copolymers via Raft Polymerization—Impact of the Synthetic Route and Activation Mechanism

Macromolecular Chemistry and Physics, Volume 224, Issue 24, December 2023., 2023
Block copolymers from poly(lactic acid) and functional acrylamides are produced via a combination of ring‐opening polymerization and photo‐iniferter reversible addition‐fragmentation chain transfer (PI‐RAFT) polymerization. The synthetic strategy is optimized toward high molecular weights while maintaining low dispersity.

The human factor: results of a small‐angle scattering data analysis round robin

Journal of Applied Crystallography, Volume 56, Issue 6, Page 1618-1629, December 2023., 2023
A data‐analysis round robin was performed using four real‐world datasets to quantify the role of the human factor in analysis; the 46 responses show that the analyses by different researchers and laboratories may not be directly comparable, with large reporting inconsistencies in distribution widths and volume fractions.

Thermo‐Responsive Ultrafiltration Block Copolymer Membranes Based on Polystyrene‐block‐poly(diethyl acrylamide)

Macromolecular Materials and Engineering, Volume 308, Issue 11, November 2023., 2023
A novel ultrafiltration membrane based on a polystyrene‐b‐poly(diethyl acrylamide) block copolymer is introduced, where the poly(diethyl acrylamide) block features an lower critical solution temperature in water at 32 °C. The membrane is fabricated via the non‐solvent induced phase separation process and the reversible thermal switching capability of ...

rTMS ameliorates depressive‐like behaviors and regulates the gut microbiome and medium‐ and long‐chain fatty acids in mice exposed to chronic unpredictable mild stress

CNS Neuroscience &Therapeutics, Volume 29, Issue 11, Page 3549-3566, November 2023., 2023
rTMS (15 Hz, 1.26 T) alleviates depressive‐like behavior of CUMS‐treated mice and regulates the flora represented by Cyanobacterium and Actinobaciota. Meanwhile, it improves polyunsaturated fatty acids (PUFAs) in hippocampus and PFC, and also upregulates C20:4N6, C20:5N3 and C20:3N3 PUFAs in the plasma.

Fabrication of Patchy Silica Microspheres with Tailor‐Made Patch Functionality using Photo‐Iniferter Reversible‐Addition‐Fragmentation Chain‐Transfer (PI‐RAFT) Polymerization

Small, Volume 19, Issue 43, October 25, 2023., 2023
Patchy silicon dioxide microspheres are fabricated via a solid‐state supported microcontact printing (µCP) routine. The amino functions introduced during the µCP process are used as anchor groups to graft tailor‐made polymeric materials from the patch area using photo‐iniferter reversible addition‐fragmentation chain‐transfer (RAFT) polymerization.

Donor–Acceptor Stenhouse Adduct‐Polydimethylsiloxane‐Conjugates for Enhanced Photoswitching in Bulk Polymers

Macromolecular Rapid Communications, Volume 43, Issue 15, August 2022., 2022
Covalent conjugation of soft polydimethylsiloxane chains to donor–acceptor Stenhouse adduct (DASA) photoswitches is used as a strategy to locally control the dyes' immediate environment when embedded in rigid matrix polymers for improved photoswitching in the bulk.

High Barrier Nanocomposite Film with Accelerated Biodegradation by Clay Swelling Induced Fragmentation

Macromolecular Materials and Engineering, Volume 307, Issue 6, June 2022., 2022
A nanocomposite film having in situ generated clay tactoids within a poly(lactic acid) matrix shows high‐performance barrier properties as well as accelerated biodegradation in an environmentally relevant wastewater medium. The film has resistance to water vapor even at high humidity, but fragments once immersed in water, which may be useful for fast ...

VEMERS 2.0: Upgrading of an Emergency Use Ventilator from a Single Mandatory Volume Control Mode of Ventilation (VEMERS 1.0) to 8 Modes of Ventilation

Journal of Healthcare Engineering, Volume 2022, Issue 1, 2022., 2022
The upgrading of an emergency use ventilator from a single mandatory volume control mode of ventilation (VEMERS 1.0) to 8 modes of ventilation (VEMERS 2.0) is described. The original VEMERS 1.0 was developed in the midst of the COVID‐19 crisis in Chile (April to August 2020) following special but nonetheless strict guidelines specified by local medical
