Advanced Functional Materials, EarlyView.Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Advanced Functional Materials, EarlyView.Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Determination of the Impedance Matching Domain of Impedance Matching Networks
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2004This paper investigates the impedance boundary of impedance matching networks analytically, graphically representing the resultant impedance matching domains. A set of explicit equations is derived to allow the rapid development of the impedance boundary of such networks.

In many applications, it is desirable to synthesize an adaptive impedance to match some "real world" system, so that when the target impedance changes, the matching impedance tracks this change and maintains a close match. In this paper we present a scheme for adaptive impedance matching formulated in the Model Reference Adaptive Systems' Control (MRAS)

Impedance Matching in RFID Tags: to Which Impedance to Match?
2006 IEEE Antennas and Propagation Society International Symposium, 2006This paper presents an analysis of impedance matching in passive radio frequency identification (RFID) tags. RFID chip impedance varies with frequency and with the power absorbed by the chip. The variation of this impedance with power can drastically affect the performance of the chip. We show how the impedance variation of the chip front makes the tag

Quasi-Orthogonal Grids with Impedance Matching
SIAM Journal on Scientific Computing, 2000This paper presents a general elliptic grid generation system based on quasi-conformal mapping for arbitrary anisotropic regions. This system can be used to construct quasi-orthogonal smooth grids with an externally specified spacing normal to the boundaries of the domain.
