The photoelectrochemical performance of six naturally occurring semiconducting sulfide minerals is investigated to simply and quickly evaluate their photovoltaic potential. The direct optical band gaps determined for these minerals are 1.36 eV for Enargite, 1.40 eV for Chalcostibite, 1.67 eV for Stephanite, 1.29 eV for Bournonite, 1.43 eV for Jamesonite and 1.66 eV for Gratonite, all in the range...
Long‐term alcohol exposure produces neuroadaptations that contribute to the progression of alcohol abuse disorders. Chronic alcohol consumption results in strengthened excitatory neurotransmission and increased α‐amino‐3‐hydroxyl‐5‐methyl‐4‐isoxazole‐propionate receptors (AMPA) receptor signaling in animal models. However, the mechanistic role of enhanced AMPA receptor activity in alcohol‐reinforcement...
In the present study, we sought to determine whether the interoceptive effects of alcohol (1 g/kg, IG) could be assessed using a Pavlovian discrimination method, in which the alcohol drug state sets the occasion for which an environmental stimulus (e.g., light) will be followed by a sucrose reward. This procedure takes advantage of a naturally occurring behavior (i.e., food-seeking) which can be trained...
