Advanced Materials, EarlyView.In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Empowering or Reinforcing Traditional Roles: Can CCTs Address Gender Vulnerabilities? [PDF]
Most conditional cash transfer (CCT) programmes in Latin America select a woman as the primary recipient of the transfer. In most cases she is the mother of children in the household or the woman responsible for those children.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
Advanced Materials, EarlyView.A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Advanced Materials, EarlyView.Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

OS MINISTÉRIOS NUMA SOCIEDADE EM VIA DE URBANIZÃO
Perspectiva Teológica, 1970 O Concilio Vaticano II prescreve aos bispos no Decreto Christus Dominus, n. 16, § 5, o seguinte: "A fim de poderem cuidar do bem dos fins de maneira mais apropriada a condições de cada um, esforcem-se para conhecer-lhes a fundo as necessidades nas ...

The Doha Round and Kenya: Good and Not So Good Lessons [PDF]
The global financial crisis and spiking unemployment figures have raised the threat of escalating barriers to trade. An early conclusion to the Doha Round might help avert some of the increase in protectionism, but no one knows by how much.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.
