A dual stimuli responsive nanogel-polyelectrolyte complex based on electrostatic coating has been developed. The nanoassembly is designed to elicit two disparate responses ( surface property change and guest encapsulation stability) from two different stimuli ( pH and redox variations). The components of the nanogel and the polyelectrolyte have been conveniently achieved from a simple homopolymer, poly(pentafluorophenylacrylate).

As an innovative branch of electronics, intelligent electronic textiles (e-textiles) have broad prospects in applications such as e-skin, human-computer interaction, and smart homes. However, it is still a challenge to distinguish multiple stimuli in the same e-textile. Herein, we propose a dual-parameter smart e-textile that can detect human pulse and body temperature in real time, with high performance and no signal interference.

Soccer players must react quickly and execute complex mental processes to adapt to competitive scenarios while maintaining peak physical performance. Perceptual-cognitive training methods integrate reaction tasks using nonspecific visual stimuli with game-like motor actions, but the impact on explosive strength responses is unclear. This study investigates the effect of nonspecific visual stimuli with varying perceptual-cognitive constraints on jump performance, including countermovement jump height, reactive strength index modified, action time, and reaction time.

The development of photoresponsive ferroelastics, which couple light-induced macroscopic mechanical and microscopic domain properties, represents a frontier in materials science with profound implications for advanced functional applications. In this study, we report the rational design and synthesis of two new organic-inorganic hybrid ferroelastic crystals, (MA)(MeN)[Fe(CN)(NO)] (MA = methylammonium) () and (MA)(MeNOH)[Fe(CN)(NO)] (), using a dual-organic molecular design strategy that exploits hydrogen-bonding interactions for tailoring ferroelastic properties. Specifically, exhibits a two-step phase transition at 138 and 242 K, while the introduction of a hydroxyl group in stabilizes its ferroelastic phase to a significantly higher temperature, achieving a phase transition at 328 K, 86 K above that of .

In this study, we constructed a pH/laccase dual responsive drug delivery system, denoted as IMI@(CMCS+SL)n, capable of modulating wall thickness and drug release via the layer-by-layer deposition of carboxymethyl chitosan (CMCS) and sodium lignosulfonate (SL). The IMI@(CMCS+SL)n microcapsules was characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), (energy-dispersive X-ray spectroscopy) EDS, X-ray photoelectron spectroscopy (XPS), and dynamic light scattering techniques (DLS) analysis. IMI@(CMCS+SL)n demonstrated not only a high loading capacity (exceeding 90 %) but also exhibited exceptional performance in sustained release and anti-termite activity of IMI.
