Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

open access: yesAdvanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Model-free adaptive chaos control for the boost converter

open access: yesMeasurement + Control
In order to solve the dynamic analysis and chaotic motion control problems of the current-mode-controlled Boost converter system, a state equation model in the continuous current mode is established.

Studies of Light Scalar Particles and Dressed Gauge Propagators in QCD [PDF]

open access: yes, 2010
The equations of QCD are widely believed to describe the properties of mesons, baryons and their hadronisation after hard interactions at particle accelerators such as the LHC.

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

Experimental Study on the Evolution of Single-Mode Interface Induced by Co-Directional Rarefaction and Shock Waves

open access: yes气体物理
Developments of a single-mode light/heavy interface accelerated by co-directional rarefaction and shock waves were investigated. Induced by the rarefaction waves, the light/heavy perturbation amplitude experiences an oscillatory growth, which is referred

The effects of nonlinear perturbation terms on comparison principles for the p-Laplacian

open access: yesBulletin of Mathematical Sciences
In this paper, we investigate various comparison principles for quasilinear elliptic equations of [Formula: see text]-Laplace type with lower-order terms that depend on the solution and its gradient. More specifically, we study comparison principles for equations of the following form: [Formula: see text] where [Formula: see text] is the [Formula: see

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

open access: yesAdvanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN

open access: yesAdvanced Functional Materials, EarlyView.
Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...

Ekeland’s variational principle for interval-valued functions with an α-level set in Kaleva-Seikkala’s type fuzzy metric spaces

open access: yesDemonstratio Mathematica
In this paper, we establish a new version of Ekeland’s variational principle in the setting of Kaleva-Seikkala’s type fuzzy metric spaces, where the objective function is an interval-valued function defined on a fuzzy metric space, and the perturbation ...

Morphoacoustic perturbation analysis: principles and validation

open access: yes, 2012
This paper presents a frequency domain technique for investigating the relationship between acoustic properties of the human hearing system and the morphology responsible for creating them. Exploiting reciprocity, the boundary element method is applied to determine head-related transfer functions (HRTFs) for various directions and distances from a ...
