Summary: In this study, an efficient Co3O4/ZnO based composite was prepared for photoelectrochemical water splitting using a low temperature aqueous chemical growth method. The composite showed superior performance due to significant increase in photocurrent density, promotion of electron-hole charge carrier separation, and favorable charge transport. Additionally, electrochemical impedance spectroscopy revealed a small charge transfer resistance for the composite material, leading to robust water splitting. The prepared composite is earth abundant, inexpensive, and scalable, making it suitable for diverse applications.

Summary: In this study, a new low-cost template-assisted synthesis method was used to fabricate vertically aligned ZnO nanorod arrays on Si (100). The nanorods were grown on a double seed layer composed of reduced graphene oxide (rGO) and Al-doped ZnO nanoparticles. The seed layer was prepared by spray-coating the substrate with graphene and dip-coating it into an Al-doped ZnO sol-gel solution. A growth template was created using a double-layer resist spin-coated on top of the rGO/ZnO:Al seed layer and patterned by colloidal lithography. The results showed successful chemical bath deposition of ZnO nanorods with controllable diameter and density in the nanoholes of the patterned resist mask. Our novel method has the potential to fabricate electronic devices on various smooth substrates with a short thermal budget and the seed layer acting as a conductive strain-relieving back contact. The top contact can be easily made by depositing a suitable transparent conductive oxide or metal, depending on the specific application.

Summary: This work demonstrates how the current phase transition of atomic Bose-Einstein condensates in a trap can be controlled by applying an oscillatory driving field. The self-trapping effect in momentum space allows for a suppression of oscillations and a nearly constant directed current. Mean-field chaos serves as an indicator of the quantum phase transition. These findings are supported by an effective three-mode model.
