Two-stage air injection for NOx reduction in ammonia-hydrogen flameless combustion

Ammonia-hydrogen blends are emerging as promising carbon-free fuels for gas turbine and industrial combustion systems. However, lean combustion typically produces high NO x emissions due to fuel-bound nitrogen in ammonia and elevated concentrations of reactive O/H radicals, while...

Realization of a Robust High-Efficiency n-Type Mg3(Sb, Bi)2/p-Type MgAgSb-Based Thermoelectric Power Generator for Harvesting Low-Grade Waste Heat

Abstract Thermoelectric generators (TEGs) enable direct conversion of waste heat into electrical energy. Although Bi2Te3-based alloys have long been the conventional thermoelectric materials, concerns over their toxicity and limited availability have encouraged the development of...

Convergent Total Syntheses of Anti ‐Diol Diastereomers of Tonkinelin Toward Its Absolute Structure Assessment

The stereoselective syntheses of (17 S ,18 R ,36 S )‐tonkinelin and its diastereomer (17 R ,18 S ,36 S )‐tonkinelin via a convergent strategy have been achieved. The strategy involved the stepwise construction of two key fragments—a chiral ester‐derived phosphonium salt and a req...

Multicolor Imaging from Bacteria to 3D Cellular Models Using Carbon Quantum Dots

Abstract Bacterial and cellular imaging at the outset allows us to visualize microbial and cellular behavior and how they interact and respond to their surroundings. However, developing biocompatible and photostable fluorescent probes for visualizing and tracking biological proce...

Effect of Morphology of Electrophoretically‐Deposited Carboxylated Graphene Over Carbon Fibers on the Tribological Properties of Epoxy Composites

ABSTRACT Graphene deposited carbon fiber epoxy composites show enhanced tensile properties through improved interfacial strength; however, improved wear resistance is also essential for demanding applications such as bearing bushings in aggressive environments. In the present stu...

LC3 forms functional nanoclusters on autophagosomes

Abstract Autophagosome biogenesis depends on the coordinated action of proteins and lipids. However, how LC3B organizes at high density and contributes to autophagy-associated functions remains unclear. Using molecular dynamics simulations and super-resolution microscopy, we show...

Betti Numbers and Higher Weight Spectra of Reed–Muller Codes \({\textrm{RM}}_{{q}}{(2,2)}\)

Abstract. We determine all the Betti numbers of the [Formula: see text]-ary second order Reed–Muller codes of length [Formula: see text], and also of the elongations of matroids associated to these codes. We then use it to determine the higher weight spectra of these codes. As a...

Measurements of the production of W$$^{\pm }$$ and Z$$^0$$ bosons in pp collisions at $$\sqrt{s} = 13$$ TeV

Abstract Measurements of the production of the W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons at midrapidity in pp collisions at $$\sqrt{s} = 13$$ s = 13 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons are detected via their (di)e...

Characterization of Integrally Closed Simple Extensions of Valuation Rings

Let $$v$$ be a Krull valuation on a field, with valuation ring $$R_v$$ . Consider the irreducible polynomial $$F(x) = x^n + a(bx^k + c)^m$$ in $$R_v[x]$$ , where $$1 \leq km < n$$ , and let $$\theta$$ be a root of $$F(x)$$ . This paper establishes necessary and sufficient conditi...

Synthesis of unsymmetrical A3B type meso-tetraaryl triphyrin(2.1.1)s.

-tetraaryl triphyrin(2.1.1) is demonstrated through the synthesis of a covalently linked ferrocene-triphyrin(2.1.1) dyad. The preliminary studies showed a possibility of photoinduced electron transfer from the ferrocene moiety to the triphyrin(2.1.1) macrocycle.

ESG disclosures, dividend payout policy, and the cost of equity. Indian evidence of a non-monotonic relationship

Purpose This study aims to analyse the non-monotonic impact of environment, social and governance (ESG) disclosures on the cost of equity of NSE 500 Indian firms from 2014 to 2023. Given the contention about the shape of the curve in the literature, the authors examine whether a...

Reengineered Vitamin B12 for Selective Aqueous Nitrate-to-Ammonium Electrocatalysis via Axial-Ligand Gating

Abstract Vitamin B12 (cobalamin) is an evolutionarily optimized Co-corrin redox cofactor capable of accessing low-valent cobalt states to mediate challenging biological transformations. Here, we reengineer this biological redox platform into an electrode-addressable catalyst for...

3D radial anisotropic imaging of magma plumbing systems beneath the Malani silicic igneous province in northwestern India

Abstract Imaging the plumbing systems of ancient silicic large igneous provinces (SLIPs) is inherently challenging due to the decay of thermal anomalies associated with SLIPs, and the erosion or masking of surface expressions by sediments. The plumbing architecture of the Neoprot...

Finite-Element-Guided Design of Metallic and Bioresorbable Bone Screws: Linking Thread Geometry, Material Stiffness, and ACL Screw Mechanics

Abstract Bone screw fixation is governed by the thread geometry, material stiffness, contact friction, and loading path. Here, a staged finite-element workflow was used to screen bone-screw designs for bone-to-bone and ACL fixation. Two-dimensional models rapidly compared thread...
