TL;DR: In this paper, the performance objectives and key performance indicators (KPIs) are identified to improve process and performance management in PPPs, and the relative significance and difference of performance objectives for different stakeholders are presented based on a structured questionnaire survey.
Abstract: Public–private partnerships (PPPs) have been applied widely in the global construction market. During the life cycle of PPP projects, their performance could be affected by a number of factors and their interactions, which might cause the inefficiency and ineffectiveness of the projects. Previous researches on PPPs mainly concentrated on the procurement, success measurement and risk management of PPPs, but paid little attention to the process factors that can strongly influence the performance of PPPs. In order to improve process and performance management in PPPs, the performance objectives and key performance indicators (KPIs) are identified to improve the partnership outcomes. Based on the goal‐setting theory, 15 performance objectives are selected. The relative significance and difference of performance objectives for different stakeholders are presented based on a structured questionnaire survey. The survey results show that all identified objectives are important. In spite of stakeholders' common op...

TL;DR: It is demonstrated that high-quality few-layer dioctylbenzothienobenzothiophene molecular crystals can be grown on graphene or boron nitride substrate via van der Waals epitaxy, with precisely controlled thickness down to monolayer, large-area single crystal, low process temperature and patterning capability.
Abstract: Inorganic two-dimensional atomic crystals exhibit a variety of unusual but practically useful properties. Here, the authors produce an organic counterpart, atomically smooth monolayers of a molecular crystal, and use this organic analogue of graphene in high-performance organic field-effect transistors.

TL;DR: A series of crystalline porphyrin-tetrathiafulvalene covalent organic frameworks are synthesized and used as photocatalysts for reducing CO2 with H2O, in the absence of additional photosensitizer, sacrificial agent and noble metal co-catalyst to confirm the structure-function relationship.
Abstract: Solar energy-driven conversion of CO2 into fuels with H2 O as a sacrificial agent is a challenging research field in photosynthesis. Herein, a series of crystalline porphyrin-tetrathiafulvalene covalent organic frameworks (COFs) are synthesized and used as photocatalysts for reducing CO2 with H2 O, in the absence of additional photosensitizer, sacrificial agents, and noble metal co-catalysts. The effective photogenerated electrons transfer from tetrathiafulvalene to porphyrin by covalent bonding, resulting in the separated electrons and holes, respectively, for CO2 reduction and H2 O oxidation. By adjusting the band structures of TTCOFs, TTCOF-Zn achieved the highest photocatalytic CO production of 12.33 μmol with circa 100 % selectivity, along with H2 O oxidation to O2 . Furthermore, DFT calculations combined with a crystal structure model confirmed the structure-function relationship. Our work provides a new sight for designing more efficient artificial crystalline photocatalysts.

TL;DR: The increased reactivity of the distorted π-electron system in strained graphene allows us to attach metal atoms and to tailor the properties of graphene.
Abstract: Reconstructed point defects in graphene are created by electron irradiation and annealing. By applying electron microscopy and density functional theory, it is shown that the strain field around these defects reaches far into the unperturbed hexagonal network and that metal atoms have a high affinity to the nonperfect and strained regions of graphene. Metal atoms are attracted by reconstructed defects and bonded with energies of about 2 eV. The increased reactivity of the distorted � -electron system in strained graphene allows us to attach metal atoms and to tailor the properties of graphene.

TL;DR: Drug loading and releasing experiments demonstrate that an anticancer drug, DOX, can be successfully encapsulated by the supramolecular vesicles, and the resulting DOX-loaded vesicle exhibit efficient release of the encapsulated DOX with the pH adjustment or the introduction of Ca(2+).
Abstract: Supramolecular binary vesicles based on the host-guest complexation of water-soluble pillar[6]arene (WP6) and SAINT molecule have been successfully constructed, which showed pH-, Ca(2+)-, and thermal-responsiveness. These supramolecular vesicles can efficiently encapsulate model substrate calcein, which then can be efficiently released either by adjusting the solution pH to acidic condition due to the complete disruption of vesicular structure, or particularly, by adding a certain amount of Ca(2+) due to the Ca(2+)-induced vesicle fusion and accompanied by the structure disruption. More importantly, drug loading and releasing experiments demonstrate that an anticancer drug, DOX, can be successfully encapsulated by the supramolecular vesicles, and the resulting DOX-loaded vesicles exhibit efficient release of the encapsulated DOX with the pH adjustment or the introduction of Ca(2+). Cytotoxicity experiments suggest that the resulting DOX-loaded supramolecular vesicles exhibit comparable therapeutic effect for cancer cells as free DOX and the remarkably reduced damage for normal cells as well. The present multistimuli-responsive supramolecular vesicles have great potential applications in the field of controlled drug delivery. In addition, giant supramolecular vesicles (~3 μm) with large internal volume and good stability can be achieved by increasing the temperature of WP6 ⊃ SAINT vesicular solution, and they might have potential applications for bioimaging.
