Two-micron spectrophotometry of the galaxy NGC 253 [PDF]
, 1979 A very strong Brackett-gamma hydrogen emission line, and the 2.3 micron CO stellar absorption feature were measured in NGC 253. The presence and strength of the CO feature indicates that late type giant stars produce most of the 2.2 micron continuum ...

Advanced Science, EarlyView.To overcome limitations of conventional AI hardware, a light‐voltage dual‐modulating synaptic (LVDS) transistor using an IGZO/InAs quantum dot hybrid structure is proposed. LVDS transistor enables analog summation for Dueling Deep Q‐Networks by independently modulating memory via optical and electrical stimuli.

Ni Single‐Atom Modulation of Ti‐O Covalency Boosts Ammonia Oxidation Electrocatalysis
Advanced Science, EarlyView.A Ni single‐atom‐induced enhancement of Ti‐O covalency in Ni SAC@TiO2 generates abundant active sites and promotes selective NHx‐NHy mediated N2 evolution while suppressing poisonous NOx formation, achieving nearly doubled AOR activity with excellent durability.

SYNTHESIS OF ETHYL FATTY ALKYL ETHERS FROM COCONUT (Cocos nucifera L.) FATTY ALCOHOLS
Annals of Tropical Research, 1987 Ethyl fatty alkyl ethers were synthesized using coconut fatty alcohols as the starting raw materials. The fatty alcohols were converted into their corresponding bromides which were then made to react with ethanolic potassium hydroxide.

SYNTHESIS AND INVESTIGATION OF THIN TiO2 FILMS, DOPED WITH COPPER NANOPARTICLES
Вестник Северо-Кавказского федерального университета, 2022 Thin films of titanium dioxide, doped with copper nanoparticles, were synthesized by the method of deposition on the rotating substrate. The obtained films were dried at room temperature and at temperature of TiO2 calcination and studied by ellipsometry,

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The suboptimal efficiency of current biomass conversion processes necessitates the optimization of biochar production methodologies to enhance desired biochar characteristics. In this study, an investigation was conducted to determine the optimal air inlet configuration within a top‐lit updraft gasifier system for enhancing biochar properties ...
