Soft microgel networks stabilize and extend nozzle-free water jets
The SAW device comprises slowness-curve-adjusted interdigital transducers (IDTs)42 arranged in a delay-line configuration to generate a strong standing wave at the chip center. This geometry focuses the acoustic energy into a well-defined interaction zone, only 1.6λSAW (FWHM) wide and approximately 25λSAW (FWHM) long, ensuring highly localized coupling between the SAW field and the fluid above. A representative microscopic image of the chip layout, overlaid with laser Doppler vibrometry (LDV) measurements of the amplitude distribution at the optimal driving frequency together with the magnitude of reflection coefficients are shown in Fig. 1b. We investigate the effect of microgel softness on SAW-driven jet formation by preparing droplets of varying volumes from microgel dispersions of three stiffness levels with 1%, 5% and 10% of nominal cross-linker concentrations (MG1, MG5, and MG10, with MG1 being the softest) at dispersion concentrations of 0.01, 0.1, and 1 wt%. These droplets are dispensed using a pipette [see Fig. 1a] and placed at the center of SAW chip. The dispensed droplet is equilibrated for 2–3 minutes prior to IDT activation. It is known that microgels adsorb at the air–water interface43 (prior to jetting), and that lower cross-linker density creates softer microgels, while higher cross-linker density produces stiffer ones44...

Although several recent platforms have achieved high-throughput collagen microgel fabrication, most rely on chemical modification or rigid process parameters that compromise native collagen structure or limit biological versatility. A scalable yet biologically unmodified system remains lacking.(2/4)

Its activity is increased by exfoliation via chemical modification to produce nanomaterials. In the present work, the modification of MMT to form nanogel composites is proposed to increase the dispersion of MMT into epoxy matrices used to fill cracks and holes produced by the curing exotherms of epoxy resins. The dispersion of MMT in epoxy improved both the mechanical and anti-corrosion performance of epoxy coatings in aggressive marine environments. In this respect, the MMT surfaces self-healing materials for epoxy coatings for steel. nanomaterials 1. Introduction RETRACTED were chemically modified with different types of 2-acrylamido-2-methyl propane sulfonic acid (AMPS) nanogels using a surfactant-free dispersion polymerization technique. The effect of the chemical structure, nanogel content and the interaction with MMT surfaces on the surface morphology, surface charges and dispersion in the epoxy matrix were investigated for use as nano-filler for epoxy coatings.

The formation of stable Mickering cyclohexane/water emulsions was investigated by using soft microgel particles of poly(acrylamide), PAAm, poly(2-acrylamido-2-methylpropane sulfonic acid), PAMPS, and sodium salt of PAMPS, PAMPS-Na, as stabilizers. The dynamic light scattering (DLS), optical microscopy, and scanning electron microscopy (SEM) were used to investigate the optimum conditions and effects of surrounding solutions on the microgels characteristics and their corresponding Mickering emulsions. The cyclohexane/water Mickering emulsions stabilized by softer and neutral charged microgels were considerably more stable under the same conditions. Furthermore, the stimuli-responsive properties of PAMPS microgel stabilized cyclohexane/water Mickering emulsions suggest the potential utility in the preparation of PS and P4-VP nanospheres. The effects of pH changes on the morphology, particle sizes, and surface charges of PS and P4-VP microgels were evaluated to prove the pH-sensitivity of Retracted article in MDPI's molecules, available at https://www.mdpi.com/1420-3049/19/7/10410 Molecules 2014, 19, 10410-10426; doi:10.3390/molecules190710410 This paper has been retracted.

Microgel-Líquido Bifásico Mitiga Polarización en Baterías de Zinc Acuosas Key Highlights Energía · Almacenamiento y Baterías Un estudio reciente, publicado en Advanced Energy Materials, presenta un electrolito bifásico microgel-líquido enriquecido con Zn²⁺ diseñado para mitigar la polarización por concentración en el ánodo de zinc en baterías acuosas avanzadas. Los investigadores demostraron que la formación in situ de un microgel dinámico de goma guar-Zn²⁺-SO₄²⁻ actúa como una reserva de Zn²⁺ que lo libera continuamente en la interfaz, supresión del efecto lanzadera de poliyoduro y logrando una vida útil de más de 5360 horas en celdas simétricas Zn‖Zn.

Star trails don’t fight the dark—they keep moving, slow and steady, until it turns gold. You’re learning that rhythm right now. Hush attention through collarbone and spine. Your exhale undoes the throat—heat cools to motion, tension shed-slick, exposed but unafraid. ✨
Overhead: iridescent microgel whorl, prismatic pulse, overhead ripple mirror—hyper-bright specular highlights with candle-warm wax hush. hypnotic star-trail disk; micro-reset light cut a beat early, shivering before the gold completion; expanded/contract rings, horizon-free loop. Phrase appears as shimmering neon-mica line: “YOUR EXHALE DRAWS RELIEF”, undoing-throat feel in an aurora-like long-exposure inside a translucent ribcage form; attention-trails as soft handwritten light, fully luminous.
