Table3_Does the scarcity of urban space resources make the quality of underground space planning more sustainable? A case study of 40 urban underground space master plans in China.XLSX
The international community has reached a consensus on promoting the sustainable development of global cities. As an important and irreversible space resource in a city, the development and utilization of urban underground space should follow the principle of sustainability and emphasize scientific and forward-looking planning. At present, most cities have formulated urban underground space master plans. However, due to the lack of an effective evaluation method, the plan quality is uneven, which directly affects the sustainability of underground space development and utilization. This paper proposes a set of sustainability evaluation framework of underground space planning based on relevant planning standards and plan quality evaluation protocol, and makes a comparative analysis of the 40 urban underground space master plans formulated in China from 2004 to 2020. The research found that the planning documents generally reflected the problem of emphasizing design strategies and engineering technology while neglecting implementation and humanistic care; administrative region, population density, land price and other variables closely related to the scarcity of urban space resources are the main factors affecting the quality of urban underground space planning. The conclusions of this paper can aid planners and researchers to identify the problems and influencing factors of underground space planning related to sustainability, and summarize the methods to improve the quality of underground space planning.</p

Insights into the Dissociation Process and Binding Pattern of the BRCT7/8-PHF8 Complex
DNA topoisomerase
2-binding protein 1 (Topbp1) plays a crucial
role in activating the ataxia-telangiectasia mutated and rad3-related
(ATR) complex to initiate DNA damage repair responses. For this process
to occur, it is necessary for PHF8 to dissociate from Topbp1. Topbp1
binds to the acidic patch sequence (APS) of PHF8 through its C-terminal
BRCT7/8 domain, and disrupting this interaction could be a promising
strategy for cancer treatment. To investigate the dissociation process
and binding pattern of BRCT7/8-PHF8, we employed enhanced sampling
techniques, such as steered molecular dynamics (SMD) simulations and
accelerated molecular dynamics (aMD) simulations, along with self-organizing
maps (SOM) and time-resolved force distribution analysis (TRFDA) methodologies.
Our results demonstrate that the dissociation of PHF8 from BRCT7/8
starts from the N-terminus, leading to the unfolding of the N-terminal
helix. Additionally, we identified critical residues that play a pivotal
role in this dissociation process. These findings provide valuable
insights into the disassociation of PHF8 from BRCT7/8, which could
potentially guide the development of novel drugs targeting Topbp1
for cancer therapy

Cationic Zinc(II) Complexes with Carbazole-Type Counter-Anions: Intracomplex Donor/Acceptor Pairs Affording Exciplexes with Thermally Activated Delayed Fluorescence
Two cationic zinc(II) complexes with
carbazole-type counter-anions,
namely, [Zn(tpy)2]2+[CAZ-p-BF3–]2 (Zn-p) and
[Zn(tpy)2]2+[CAZ-o-BF3–]2 (Zn-o), have been
designed and synthesized, where tpy is 2,2′:6′,2″-terpyridine,
CAZ-p-BF3– is 4-((9H-carbazol-9-yl)phenyl)trifluoroborate, and CAZ-o-BF3– is (2-(9H-carbazol-9-yl)phenyl)trifluoroborate. The complex cation [Zn(tpy)2]2+ (as the acceptor) and the carbazole-type counter-anion
CAZ-p-BF3– or CAZ-o-BF3– (as the donor) form
an intracomplex donor/acceptor pair. Single-crystal structures reveal
that compared to Zn-p, Zn-o exhibits
a stronger π–π stacking interaction between the
carbazole group (as the donor unit) of the counter-anion and the tpy
ligand (as the acceptor unit) of [Zn(tpy)2]2+ because of the different anchoring position of the BF3– anion in the counter-anion. In a doped film,
Zn-p and Zn-o afford an isolated
exciplex formed between the carbazole group and the tpy ligand within
the single complex, which gives green-yellow emission with a thermally
activated delayed fluorescence (TADF) feature. In crystalline states,
Zn-p and Zn-o afford exciplexes
with blue emission centered at 468 nm and green-blue emission centered
at 508 nm, respectively. The Zn-p crystalline sample
shows a relatively large singlet–triplet energy gap (ΔEST) (0.33 eV) and no TADF, whereas the Zn-o crystalline sample exhibits a small ΔEST (0.06 eV) and distinct TADF, with a reverse intersystem
crossing rate at 3.3 × 105 s–1.
Zn-p and Zn-o both exhibit intriguing
mechanochromic luminescence, with largely red-shifted (by over 70
nm) emission and modulated TADF properties upon mechanically grinding
the crystalline samples. The work demonstrates that donor/acceptor
pairs affording exciplexes can be formed within cationic metal complexes
using counter-anions with donor nature, which opens a new avenue toward
photo-active metal complexes with rich photophysical properties
