Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

open access: yesAdvanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

$δ$-PVDF Based Flexible Nanogenerator [PDF]

open access: yesarXiv, 2021
Delta ($\delta$) phase comprising polyvinylidene fluoride (PVDF) nanoparticles are fabricated through electrospray technique by applying 0.1 MV/m electric field at ambient temperature and pressure, which is 10$^{3}$ times lower than the typical value, required for $\delta$-phase transformation.

Investigating the Structure–Function Relationships of Fluorinated Interfaces for PFAS Capture and Electrochemically‐Mediated Release

open access: yesAdvanced Functional Materials, EarlyView.
This study explores the use of fluorinated copolymers with varying fluorophilic side chain lengths to enhance PFAS affinity. The integration of electrochemical techniques demonstrates enhanced adsorbent regeneration, with molecular dynamics simulations providing insight into the molecular‐level interactions involved.

FALSE SUGAR SEQUENCE PHENOMENON AND STRUCTURAL ANALYSIS OF α-HEDERIN AND HEDERACOSIDE C THROUGH ELECTROSPRAY IONIZATION AND MULTI-STAGE TANDEM MASS SPECTROMETRY

open access: yesVitae, 2011
Saponins are glycosides regularly found in plants, and they are frequently analyzed by means of electrospray ion sources and tandem mass spectrometry (ESI/MSn), not only to obtain an overall molecular weight through the high sensitivity of mass ...

Biodegradable PLGA Microsphere Formation Mechanisms in Electrosprayed Liquid Droplets

open access: yesKONA Powder and Particle Journal, 2021
Microspheres composed of poly (lactic-co-glycolic acid) (PLGA) were formed in liquid droplets using the electrospray technique. The structure of the microspheres was controlled by changing the electric voltage of the electrospray.

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

open access: yesAdvanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

An rf-carpet electrospray ion source to provide isobaric mass calibrants for trans-uranium elements [PDF]

open access: yes, 2012
For trans-uranium elements, stable atomic isobars do not exist. In order to provide isobaric reference ions for the mass measurement of trans-uranium elements, an electrospray ion source (ESI) was combined with an rf-carpet to collect molecular ions efficiently.

Asymmetric Nanofiber Membranes for Simultaneous Moisture Adsorption and Rapid Catalytic Hydrolysis of Nerve Agent Simulants in Atmospheric Environments

open access: yesAdvanced Functional Materials, EarlyView.
Asymmetric nanofiber membranes are constructed for simultaneous moisture adsorption and catalytic hydrolysis of dimethyl 4‐nitrophenyl phosphate (DMNP) in a wide range of relative humidity. The membrane exhibits high moisture adsorption capacity and fast hygroscopic rate.

DESIREE electrospray ion source test bench and setup for Collision Induced Dissociation experiments [PDF]

open access: yes, 2018
We give a detailed description of an electrospray ion source test bench and a single-pass setup for ion fragmentation studies at the DESIREE infrastructure at Stockholm University. This arrangement allows for collision induced dissociation experiments at center-of-mass energies between 10 eV and 1 keV.
