Flattening Energy Puddles for Enhanced Charge Transport in Wrinkled WSe2

open access: yesSmall, EarlyView.
Strain‐inducing wrinkles in 1L‐WSe2 create carrier‐trapping energy puddles. Trioctylphosphine selenide (TOPSe) selectively passivates Se vacancies at these wrinkle sites, while steric hindrance suppresses basal‐plane reaction. Comprehensive suite of space‐resolved spectroscopic techniques reveals reduced nonradiative recombination, longer exciton ...

Chalcogen‐Directed Dual‐Heterointerfaced Bi2Te3/BiSx in N‐Doped Carbon Nanofibers for Sodium Storage

open access: yesSmall, EarlyView.
Dual crystalline/amorphous heterointerfaces of Bi2Te3/BiSx encapsulated in N‐doped porous carbon nanofibers are engineered as an advanced anode for sodium‐ion batteries. The synergistic heterointerfaces and Te vacancies enable fast charge transport, buffer volume expansion, and ensure structural integrity. The anode delivers exceptional rate capability

Superiority of CuSe as a non-nobel electrocatalyst among copper chalcogens for overall water splitting reactions

open access: yesEnergy Nexus
Among the transition metals copper is one of the cheapest earth- abandoned elements which can enhance electrocatalytic activity. The Cu-based catalysts are superior for catalytic performance and stability in alkaline media for oxygen evolution reaction ...

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

open access: yesThe FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Complex magnetic exchange, anisotropy and skyrmionic textures in 2D ferromagnets with transition metals and chalcogens

open access: yesnpj 2D Materials and Applications
Recently resynthesized FeNbTe2 has been confirmed to exhibit ferromagnetism. Using first-principles methods, we investigate the magnetic properties of two-dimensional FeXZ2 (X = Nb, Ta; Z = S, Se, Te) compounds, including their non-centrosymmetric Janus ...

Detection of Toxic Gases and Volatile Organic Compounds Using Highly Adsorptive Nanomaterials: A Comprehensive Assessment

open access: yesEcoMat, Volume 8, Issue 5, May 2026.
This review highlights how nanomaterials with high adsorption capacities including carbon‐based structures, transition metal oxides, 2D layers, and zeolites enable sensitive and selective detection of toxic gases and VOCs. Their tailored properties and sensing mechanisms drive the development of next‐generation gas sensors for environmental and ...

Addition Reactions of Phosphorus‐Centered Radicals Onto Olefins: Interplay Between Stability and Reactivity

open access: yesChemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
The energetics of the addition reaction of P‐centered radicals onto alkenes are primarily ruled by the stability of the attacking radical, as outlined by the computational screening of a wide range of reactions. In addition, donor‐acceptor substituents at the olefin have an important tuning role.

Challenges in Simultaneous Microstructuring and Hyperdoping of Germanium with Ultrafast Laser

open access: yesphysica status solidi (a), Volume 223, Issue 8, 22 April 2026.
Femtosecond laser processing is explored as a single‐step route to microstructure and hyperdope germanium for extended infrared absorption. Comparative experiments with and without a Ti precursor reveal that Ge's shallow green light absorption and low thermal conductivity drive intense localized melting, evaporation, and redeposition. Post‐cleaning and

Electrochemical Regioselective Chalcogenocyclizations of 2‐Alkynylbenzamides in Flow

open access: yesChemElectroChem, Volume 13, Issue 8, 15 April 2026.
A sustainable electrochemical method enables regioselective 6‐endo‐dig chalcogeno‐cyclizations of ortho‐alkynylbenzamides in continuous flow. Using diphenyl diselenide as an electroactive coupling partner, the process avoids metals and stoichiometric oxidants, offering scalable access to selenium‐containing heterocycles.
