Papa pajchay, Primer aporte de las papas
Allpanchis, 1971 El papa pajchay o primer aporque de las papas se hace en forma colectiva o mink'a. En el distrito de Ocobamba no ha perdido nada de su originalidad. La persona que hace ejecutar el trabajo en su chacra, elige con anticipación a un capitán, cargo que recae generalmente en alguno de sus compadres u otros parientes espirituales. El capitán es el encargado

Ion Crowding Effect in Unilaterally Downsized Perovskite Memristors
Advanced Science, EarlyView.The downscaling of perovskite memristors incorporating monocrystalline nanoplates is accompanied by an ion crowding effect, which greatly enhances the local electric field in the vicinity of electrode. The highly controlled crowding of anions and vacancies results in anisotropic switching characteristics as well as unique morphology modification ...

Comparative 1‐Propanol Vapor Sensing Performance of 3D MAPbBr3 and 2D (PEA)2PbBr4
Advanced Electronic Materials, EarlyView.Both MAPbBr3 and (PEA)2PbBr4 perovskites exhibit exceptional sensitivity to 1‐propanol, a biomarker for lung cancer, with responses of 106 and 107 at 6000 and 7000 ppm, respectively. Notably, (PEA)2PbBr4 demonstrates superior sensitivity at low concentrations (90‐1,750 ppm).

Advanced Energy and Sustainability Research, EarlyView.The dilution of gaseous products obtained at high‐current densities during CO2 electroreduction or water electrolysis enables their accurate quantification via online gas chromatography, which is crucial for reliable catalyst benchmarking. The corresponding Faradaic efficiencies can then be calculated with low deviations using two different instruments,
