Impressive and dissuasive management practices in teacher professional development. Experience from public primary school teachers upgrading professional qualifications in Tanzania

Social Sciences and Humanities Open
Despite Head Teachers (HTs) and District Education Officers (DEOs) recognized as key actors in promoting Teacher Professional Development (TPD) in Tanzania, only a small portion of teachers have upgraded their professional qualifications, and there has ...

Two-plasmon-decay instability stimulated by dual laser beams in inertial confinement fusion

Matter and Radiation at Extremes
Two-plasmon-decay instability (TPD) poses a critical target preheating risk in direct-drive inertial confinement fusion. In this paper, TPD collectively driven by dual laser beams consisting of a normal-incidence laser beam (Beam-N) and a large-angle ...

Tunneling magnetoresistance effect in Co/TPD granular films

, 2009
A series of Cox(TPD)1-x granular film samples were fabricated by co-evaporating technique, where Co nanoparticles are dispersed in TPD molecules matrix. The HRTEM images show typical microstructural characteristic of granular films.

Photochemical afterglow of single organic molecules with wide‐range tunable lifetime

PhotoMat, EarlyView., 2023
“All‐in‐one” strategy was used to achieve photochemical afterglow in single organic molecule, with second‐to‐hour range tunable lifetime by tailoring the electron‐withdrawing ability of substituents. Abstract Background Photochemical afterglow that relies on slow release of photons from the chemical energy stored by light pre‐irradiation has emerged as

Structural and Chemical Dynamics of Cu/NiO/Cu(100) Surfaces During CO2 Hydrogenation

Angewandte Chemie International Edition, EarlyView.
Dynamic segregation as a design principle for Cu–Ni catalysts. Operando LEEM/XPEEM tracks reduction, reshaping, and surface segregation processes taking place in Cu‐encapsulated NiO islands supported on Cu(100) during CO2 hydrogenation. ABSTRACT Understanding the dynamic restructuring of bimetallic catalysts under reaction conditions is key to ...
