Additively manufactured MEMS multiplexed coaxial electrospray sources for high-throughput, uniform generation of core-shell microparticles.

Lab on a Chip, 2016
This study reports the first MEMS multiplexed coaxial electrospray sources in the literature. Coaxial electrospraying is a microencapsulation technology based on electrohydrodynamic jetting of two immiscible liquids, which allows precise control with low

Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction

Advanced Materials, EarlyView.
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...

Charge emissions from Electrosprays in vacuum: mixtures of formamide with methylammonium formate [PDF]

D. Garoz y J. Fernandez de la Mora, Journal of Applied Physics, vol. 113, n. 6, pp. 064901-064901-8, feb. 2013
The charge/mass distribution f(q/m) of nanodrops and ions electrosprayed in vacuum from mixtures of formamide (FM) and methylammonium formate (MAF) is studied by time of flight mass spectrometry at MAF/FM volumetric concentrations of 5%, 10%, 25% and 50%.

Nanoengineering of Chitosan Sponges Via Atomic Layer Deposition of ZnO for Water Remediation Technologies

Advanced Materials Interfaces, EarlyView.
Chitosan sponges are modified with ZnO through atomic layer deposition (ALD) to enhance water remediation. Characterization reveals the growth of defective ZnO, which improves the water stability of the sponges. The material's effectiveness is demonstrated through the removal of Direct Blue 78 dye and the photocatalytic degradation of Naproxen ...

Toward Personalized Stationary Chromatography Phases: Equipping Commercial Silica Phases with Selected Peptide‐Based Binding Domains to Tailor Affinity

Advanced Materials Interfaces, EarlyView.
The 7‐mer peptide motifs QFFLFFQ, QFFEFFQ, and QFQQSFF, known as good, medium, and poor binders for the photosensitizers m‐THPC and Chlorin E6 are covalently immobilized on commercial amino‐functionalized silica particles by inverse electron‐demand Diels‐Alder ligation.

Screening of electrospray-operating parameters in the production of alginate–royal jelly microbeads using factorial design

Journal of Pharmacy and Bioallied Sciences, 2020
Introduction: Royal jelly (RJ) has been consumed as food or as a supplement because of its high nutritional and medicinal values. A fresh harvested RJ is yellowish to whitish in color and contains proteins, free amino acids, lipids, vitamins, and sugar ...

Anti‐Counterfeiting Tags with Camouflaged QR Codes on Nanocavities, Using Polymer‐Dispersed Liquid Crystals

Advanced Materials Technologies, EarlyView.
A QR code, printed through a commercial printer on a thin plastic foil, pre‐coated with a nanocavity is proposed as an anti‐counterfeiting label. Nanocavity imparts distinctive optical properties in terms of light reflection and transmission. A thin layer of polymer‐dispersed liquid crystals (PDLC) is used to camouflage the QR code, that become ...

Suppression of collision-induced dissociation in a supersonically expanding gas [PDF]

In high-resolution mass spectrometry, an electrospray ionization source is often paired with an ion-funnel to enhance ion transmission. Although it is established that ions experience collision-induced dissociation as they pass through this device, the impact of gas-flow dynamics on ion fragmentation remains unexplored.

Electrospray characterization of perrhenate systems

Journal of the American Society for Mass Spectrometry, 2001
The electrospray negative ion mode (ESI-) mass spectrometry study of freshly prepared perrhenate in the ammonium and alkali metal (Na and K) solutions has been detailed. The cone voltage dependency of the negative ion abundance clearly indicates that the collision-activated dissociation (CAD) process in the cone-to-skimmer region is the source for both
