Advanced Materials, EarlyView.Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

On Topology of Fuzzy Strong b-Metric Spaces
Journal of New Theory, 2018 In this study, we introduce and investigate the concept of fuzzy strong b-metric space such that is a fuzzy analogy of strong b-metric spaces. By using the open balls, we define a topology on these spaces which is Hausdor® and first countable. Later

Common Fixed Point Theorems for Commutating Mappings in Fuzzy Metric Spaces
Abstract and Applied Analysis, 2012 We generalize Jungck's theorem in Jungck (1976) to fuzzy metric spaces and prove common fixed point theorems for commutative mappings in fuzzy metric spaces.

Advanced Materials, EarlyView.Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Advances in Halide Perovskites for Photon Radiation Detectors
Advanced Materials Technologies, EarlyView.This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Fixed Point Theorems for Multivalued Mappings in Neutrosophic Fuzzy Metric Spaces [PDF]
Neutrosophic Sets and SystemsFor multivalued mappings, Fixed point theorems are examined in this study within the context of Neutrosophic fuzzy metric spaces (NFMS), which are a further period of classical fuzzy metric spaces (FMS) that enable a more sophisticated depiction of ...

Convergence in Fuzzy Semi-Metric Spaces [PDF]
Mathematics, 2018 The convergence using the fuzzy semi-metric and dual fuzzy semi-metric is studied in this paper. The infimum type of dual fuzzy semi-metric and the supremum type of dual fuzzy semi-metric are proposed in this paper. Based on these two types of dual fuzzy semi-metrics, the different types of triangle inequalities can be obtained.

Advanced Materials Technologies, EarlyView.ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Some Topological Characteristics of q-Rung Orthopair Fuzzy Metric Space
Advances in Fuzzy SystemsThis paper introduced a novel concept of q-rung orthopair fuzzy (q-ROF) metric spaces, in connection with the idea of q-ROF sets, which generalizes well-known concepts of fuzzy metric spaces and intuitionistic fuzzy metric spaces.

Математичні СтудіїThe Fr\'echet distance between curves in metric spaces is known to have its fuzzy counterpart. In the present note we consider the fuzzy discrete distance between sequences of points in fuzzy metric spaces. Also, discrete curves in non-Archimedean fuzzy
