Prefabricated construction involves manufacturing components in a factory and then transporting them to a construction site for assembly, yielding resource savings and improved efficiency. However, the large size and weight of prefabricated components, along with strict delivery requirements, introduce logistical challenges, such as increased carbon emissions during transport and site congestion. This study addresses the dual-objective vehicle scheduling problem for prefabricated components.

GO/Co-MOF/PPy-350 (GPC-350) was synthesized by in situ growth of ultrafine Co-MOF on graphene oxide (GO), followed by encapsulation with polypyrrole (PPy) and calcination at 350.0℃. Meanwhile, MoS-MWCNTs (MoS-CNTs) were produced via the in situ synthesis of MoS within multi-walled carbon nanotubes (MWCNTs).

To enhance the volumetric energy density and initial coulombic efficiency (ICE) of titanium oxide (TiO) as anode electrode material for lithium-ion batteries (LIB), this study employed a surface-confined in-situ inter-growth mechanism to prepare a TiO embedded carbon microsphere composite. The results revealed that the composite exhibited a highly integrated structure of TiO with oxygen vacancies and carbon, along with an exceptionally small specific surface area of 11.52 m/g.

The CO-epoxide addition to cyclic carbonate is of great significance but usually requires high temperatures and CO pressures. Herein, a spirobifluorene-based porous organic polymer catalyst is designed with a Co-salen complex immobilized on the backbone (ST-CoSalen-POP) to enable CO fixation under mild conditions. ST-CoSalen-POP possesses a high Co-loading content (9.
