Allowable solar flux densities for molten-salt receivers: Input to the aiming strategy
Results in Engineering, 2020 Solar Power Tower technology requires accurate models and tools to assist in design and operation stages. The heliostat field aiming strategy seeks the maximization of the thermal output from the receiver, while preventing its permanent damage because of

Advanced Functional Materials, EarlyView.The shape of guanine self‐assemblies is tuned by introducing alkyl (G8), fluoroalkyl (G8f), and oligoether (G8g) side chains into the G moiety. The scanning tunneling microscopy results and calculations show that the presence and type of the side chain strongly affect the G self‐assembly network.

Study on Outlet Temperature Control of External Receiver for Solar Power Tower
Energies, 2021 Due to the change of direct normal irradiance (DNI) and the change of output power load, the receiver of the solar tower is in an unstable state in the actual operation. In this paper, a 100 MW external cylindric receiver is designed and modelled.

Advanced Functional Materials, EarlyView.A reactive in situ solution complexation strategy reconstructs the surface of 2.0 eV ultra‐wide‐bandgap perovskites via proton transfer. This chemical modulation eliminates metallic defects and induces a degenerate‐like n‐type surface, establishing an Ohmic tunneling contact.

Advanced Functional Materials, EarlyView.Auxeticity‑by‑Assembly converts freeform photovoltaics from cut‑defined layouts to assembly‑defined systems. Standardized interlocking units generate negative‑Poisson‑ratio, reconfigurable architectures, while hinge regions are wired by selectively activatable AgNW–GO@EGaIn composite interconnects and a folding‑enabled interconnector layer. A decimeter‑

Advanced Materials, EarlyView.The seminal transformation of a 2D‐COF (SURFCOF‐IMDEA1) into a 2D porous COF (SURFCOF‐IMDEA2) on Au(111) by a sequential C‐C coupling and ladderization triggered by thermal annealing steps at increasing temperatures is reported. Abstract The development of covalent organic frameworks (COFs) is currently a primary objective in materials science, taking ...
