This review provides a comprehensive overview of polymers bearing five‐membered cyclic carbonate (5CC) moieties, highlighting their role in advancing CO 2 utilization and their unique applications based on 5CC moieties. 5CC structures are highly promising due to their unique chemical properties and the fact that their…
Abstract Data on the oligomerization of lower olefins on micro- and mesoporous aluminosilicates and on regular trends observed in the process are summarized. The oligomerization mechanisms for individual components are presented. Propylene oligomerization on structured microporous materials, zeolites of BEA, MOR, SSZ,…
ABSTRACT In this study, various types and concentrations of ultrafine fully vulcanized powdered natural rubbers (UFPNR) were evaluated on how they affect the toughness of bisphenol A polybenzoxazine (PBA‐a). UFPNR types were prepared by grafting acrylonitrile (AN), styrene (ST), styrene–acrylonitrile copolymer (ST/AN)…
Abstract Corrosion remains a critical limitation in advanced engineering materials, particularly under aggressive and multi-environment conditions. High-entropy alloys (HEAs) have emerged as promising candidates for corrosion applications due to their multi-principal-element design and their ability to form chemically…
This repository contains the manuscript and accompanying source package for “Exact Rotational Gap and Mass-Distribution-Controlled Localization in an FCC Granular Lattice.” The work studies rotational and coupled translation–rotation dynamics in a three-dimensional face-centered-cubic (FCC) granular lattice with linea…
ABSTRACT Electrospun PVA scaffolds containing diclofenac‐loaded Mobil Composition of Matter No. 41 (MCM‐41)/cellulose nanocrystals (CNC) nanocomposites were developed as wound dressing platforms. Initially, CNC extracted from Buriti petioles were combined with MCM‐41 to form a hybrid nanocomposite, which was subsequen…
The title compound, C 7 H 14 O 6 , was prepared from an equimolar mixture of D- and L-sorbose (D:L = 1:1) by Fischer glycosidation in methanol and crystallized from water. The title compound crystallizes in the orthorhombic space group Pna 2 1 . The asymmetric unit contains one molecule each of methyl α-D-sorboside an…
Abstract Indium gallium nitride (InGaN) has attracted considerable attention for ultraviolet (UV) optoelectronic applications due to its tunable bandgap and compatibility with GaN-based device platforms. However, the optoelectronic performance of InGaN is strongly influenced by lattice strain, indium distribution, sur…
High-energy electropulsing triggers recrystallization and phase transformation via excessive Joule heating, potentially causing unwanted damage and compromising the bulk microstructure. Herein, a non-destructive, low-energy electric current strategy, termed electroshock treatment (EST), is developed to strengthen grai…

A dual-polarized, multi-band antenna array based on double layers of metasurface is introduced. The proposed antenna consists of a novel 1 by 2 array structure layer and two layers of an 8 × 9 arrays of metasurfaces (MS), providing coverage of frequency bands from 4.54 to 5.94 GHz, from 6.98 to 8.25 GHz and from 9.15…
Multiple resonance (MR) emitters have attracted considerable attention owing to their narrowband emission and high efficiency in organic light-emitting diodes (OLEDs). Although carbonyl incorporation into MR frameworks is an effective strategy for enhancing spin-related excited-state processes, synthetic approaches fo…
Abstract Two-dimensional (2D) halide perovskites have emerged as promising materials for optoelectronic applications due to their excellent environmental stability and tunable band structures. Compositional engineering enables tailored optical and electronic properties while also introducing multiphase heterogeneity a…
The influence of both cold and hot curing modes on the specific volume resistance of coatings obtained from the organosilicate composition OS-51-03 and the KO-921 varnish was studied. Based on the obtained results, the possibility of using one of the parameters characterizing the electrophysical properties of coatings…
Studies on the mechanics of nanomaterials, and nanostructures have driven significant discoveries and advances through multiple approaches, including experimental nanomechanics, computational nanomechanics, and size-dependent continuum theories. However, these approaches have inherent limitations related to measuremen…
Obligate acidophilic bacteria of the genus Acidithiobacillus are widely used and well known in the biomining industry. Over the past decade, it has been shown that bacterial activity can be determined in short-term experiments via amperometric measurements of microbial oxygen consumption, as changes in the Clark elect…
Microplastic (MP) contamination of food-grade salt represents an increasing food safety concern, yet practical household-level mitigation strategies are limited. This study evaluated the effectiveness of the traditional Sri Lankan coconut shell-based salt pot (lunu polkatta) in reducing MP contamination in food-grade,…
Magnetic materials dominated by shape anisotropy constitute an indispensable category of functional materials in scientific research and industrial applications. Beyond the switching field of the phases (nanowires) themselves, long-range magnetostatic interactions exert a fundamental influence on their magnetization m…
This study investigates carrier transport and confinement within multiquantum well (MQW) AlGaN‐based UV light‐emitting diodes (LEDs), based on three different MQW structures that have a marker QW: 6‐MQW, 12‐MQW, and 21‐MQW. The main emission is at 233 nm, with one marker QW emitting at 250 nm included. Through electro…
This paper proposes a novel theoretical framework, the Dark Matter Phase Network (DMPN), centered on the hypothesis that dark matter undergoes phase transitions, potentially explaining several unresolved mysteries in cosmology and astrophysics. The DMPN posits that dark matter, rather than existing as a homogenous dis…
