(Invited) Influence of Nd3⁺ Doping and Thermal Annealing on Luminescent Properties and Thermal Sensing of Na₂Ti₆O₁₃ Nanocrystals

Chemistry – An Asian Journal, EarlyView.
The effects of Nd3+ doping and thermal annealing on Na₂Ti₆O₁₃ nanocrystals are systematically studied with respect to their luminescent and thermal sensing properties. Optimal doping and annealing enhance crystallinity, emission intensity, and thermal sensitivity.

Visible Light‐Mediated Preparation of a Key Intermediate Employed in the Synthesis of Zolpidem and Several Analogs

Chemistry – An Asian Journal, EarlyView.
A new visible light‐induced method is reported for the C3‐alkylation of imidazo[1,2‐a]pyrimidines and ‐pyridines with aryldiazoacetates. This protocol can be performed in open air and serves as a convenient entry to several known and new molecules. A formal synthesis of zolpidem is achieved by changing the alkylating agent to an appropriate hypervalent

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

Astronomische Nachrichten, EarlyView.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

A novel decision support system for designing and assessing phytoremediation‐to‐biofuel value chains

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The design of biofuel value chains is a complex process due to the large number of stakeholders involved, seasonality in feedstock availability, security of supply, logistics costs, efficiency considerations, and its multi‐node nature. Decisions on designing phytoremediation‐to‐biofuel value chains are even more complicated, due to the ...
