Multi‐Talented Bismuthinidenes: Double C(sp3)─I Bond Activation Using Single or Two Bi Centers.
Chemistry – A European Journal, EarlyView.A study illustrating a tunable reactivity for bismuthinidene complexes toward dihalomethanes is presented. Two types of double activation of C(sp3)─I bonds of diiodomethane were observed depending on the structure of the ligand. When a Dipp group was present on the nitrogen, the first C─I bond underwent oxidative addition (OA) toward the bismuth ...

Chemical Properties of an Aryloxenium Cation with a Triplet Electronic Ground State
Chemistry – A European Journal, Accepted Article.Aryloxenium cations contain a formally positively‐charged, monovalent oxygen atom with an incomplete electron shell. In spite of this unusual structural element, they are key intermediates in many important processes, such as biological oxidation reactions and the industrial generation of thermoplastics.

A subclass of pseudo-type meromorphic bi-univalent functions
Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2020 In this paper, In the present article, a new subclass of pseudo-type meromorphic bi-univalent functions is defined on △={z |:z∈C and 1<|z|<∞}, we derive estimates on the initial coefficient |b₀|, |b₁| and |b₂|. Relevant connections of the new results with various well-known results are indicated.

Coefficient estimates for certain subclasses of analytic and bi-univalent functions
Filomat, 2015 For ? ? 0 and 0 ? ? < 1 < ?, we denote by K(?,?,?) the class of normalized analytic functions satisfying the two sided-inequality ? < K (Zf'(z)/f(z) + z2f''(z)/f(z))<? (z ? U), where U is the open unit disk. Let K? (?, ?, ?) be the class of bi-univalent functions such that f and its inverse f-1 both belong to the class K(?, ?,

On subclasses of M-fold symmetric bi-univalent functions
, 2021 WOS:000637030800028 In this study, we introduce and investigate two new subclasses of the biunivalent functions which both f (z) and f(-1) (z) are m-fold symmetric analytic functions. Among other results, upper bounds for the coefficients vertical bar a(m+1)vertical bar and vertical bar a(2m+1)vertical bar are found in this investigation.

Phase Diagram‐Guided Molten Salt Engineering of Biocarbon Pores at Low Temperatures
Small, EarlyView.This study pioneers a phase diagram‐guided molten salt activation strategy to engineer the pore structure of biocarbon at low temperatures. It achieves a specific surface area of ≈2500 m2 g−1 with tunable pore size at only 500 °C and uncovers the pore evolution mechanism.
