Data_Sheet_1_A study on the impact of health shocks on subjective wellbeing of middle-aged people and older adults—Evidence from China.pdf
IntroductionThe health issues that afflict middle-aged people and older individuals are a significant factor that affects their quality of life. It is crucial to investigate the impact of health shocks on the subjective wellbeing of this demographic and the mechanisms that underlie this impact to promote healthy aging.MethodsThis study utilized data from the China Family Panel Study in 2018 and 2020 to analyze the effects of HSs and their categories on the subjective wellbeing of middle-aged people and older individuals using the propensity score matching difference-in-differences method. Additionally, the study explored the mediating role of social participation.ResultsThe findings indicate that health shocks, both chronic and acute, diminish the subjective wellbeing of middle-aged people and older adults. Furthermore, these shocks have a more significant negative effect on the subjective wellbeing of individuals aged 60 and above, women in the middle-aged and older demographic, individuals in rural areas who belong to the middle-aged and older age groups, and individuals possessing activities of daily living. The mechanism analysis revealed that health shocks, both chronic and acute, reduce the subjective wellbeing of middle-aged people and older individuals by disrupting partnerships.DiscussionLowering the possibility of health shocks, the government should build a strong health management system and improve the health insurance system to enable timely treatment for persons suffering from health shocks. Individuals and families should live healthy lives and engage in social activities to avoid health shocks and improve subjective wellbeing.</p
Silicene Flowers: A Dual Stabilized Silicon Building Block for High-Performance Lithium Battery Anodes
Nanostructuring is a transformative
way to improve the structure stability of high capacity silicon for
lithium batteries. Yet, the interface instability issue remains and
even propagates in the existing nanostructured silicon building blocks.
Here we demonstrate an intrinsically dual stabilized silicon building
block, namely silicene flowers, to simultaneously address the structure
and interface stability issues. These original Si building blocks
as lithium battery anodes exhibit extraordinary combined performance
including high gravimetric capacity (2000 mAh g<sup>–1</sup> at 800 mA g<sup>–1</sup>), high volumetric capacity (1799
mAh cm<sup>–3</sup>), remarkable rate capability (950 mAh g<sup>–1</sup> at 8 A g<sup>–1</sup>), and excellent cycling
stability (1100 mA h g<sup>–1</sup> at 2000 mA g<sup>–1</sup> over 600 cycles). Paired with a conventional cathode, the fabricated
full cells deliver extraordinarily high specific energy and energy
density (543 Wh kg<sub>ca</sub><sup>–1</sup> and 1257 Wh L<sub>ca</sub><sup>–1</sup>, respectively) based on the cathode
and anode, which are 152% and 239% of their commercial counterparts
using graphite anodes. Coupled with a simple, cost-effective, scalable
synthesis approach, this silicon building block offers a horizon for
the development of high-performance batteries
Table_1_Identification of altered metabolic functional components using metabolomics to analyze the different ages of fruiting bodies of Sanghuangporus vaninii cultivated on cut log substrates.XLSX
Sanghuangporus vaninii is a profitable traditional and medicinal edible fungus with uncommon therapeutic properties and medicinal value. The accumulation of active ingredients in this fungus that is used in traditional Chinese medicine is affected by its years of growth, and their pharmacological activities are also affected. However, the effects of age on the medicinal value of fruiting bodies of S. vaninii cultivated on cut log substrate remain unclear. In this study, an untargeted liquid chromatography mass spectrometry (LC-MS)-based metabolomics approach was performed to characterize the profiles of metabolites from 1-, 2- and 3-year-old fruiting bodies of S. vaninii. A total of, 156 differentially accumulated metabolites (DAMs) were screened based on the criterion of a variable importance projection greater than 1.0 and p < 0.01, including 75% up regulated and 25% down regulated. The results of enrichment of metabolic pathways showed that the metabolites involved the biosynthesis of plant secondary metabolites, biosynthesis of amino acids, central carbon metabolism in cancer, steroid hormone biosynthesis, linoleic acid metabolism, prolactin signaling pathway, and arginine biosynthesis, and so on. The biosynthesis of plant secondary metabolites pathway was significantly activated. Five metabolites were significantly elevated within the growth of fruiting bodies, including 15-keto-prostaglandin F2a, (4S, 5R)-4,5,6-trihydroxy-2-iminohexanoate, adenylsuccinic acid, piplartine, and chenodeoxycholic acid. 15-keto-prostaglandin F2a is related to the pathway of arachidonic acid metabolism and was significantly increased up to 1,320- and 535-fold in the 2- and 3-year-old fruiting bodies, respectively, compared with those in the 1-year-old group. The presence of these bioactive natural products in S. vaninii is consistent with the traditional use of Sanghuang, which prompted an exploration of its use as a source of natural prostaglandin in the form of foods and nutraceuticals. These findings may provide insight into the functional components of S. vaninii to develop therapeutic strategies.</p
Nature-Inspired Surface Engineering for Efficient Atmospheric Water Harvesting
Atmospheric water harvesting is a sustainable solution
to global
water shortage, which requires high efficiency, high durability, low
cost, and environmentally friendly water collectors. In this paper,
we report a novel water collector design based on a nature-inspired
hybrid superhydrophilic/superhydrophobic aluminum surface. The surface
is fabricated by combining laser and chemical treatments. We achieve
a 163° contrast in contact angles between the superhydrophilic
pattern and the superhydrophobic background. Such a unique superhydrophilic/superhydrophobic
combination presents a self-pumped mechanism, providing the hybrid
collector with highly efficient water harvesting performance. Based
on simulations and experimental measurements, the water harvesting
rate of the repeating units of the pattern was optimized, and the
corresponding hybrid collector achieves a water harvesting rate of
0.85 kg m–2 h–1. Additionally,
our hybrid collector also exhibits good stability, flexibility, as
well as thermal conductivity and hence shows great potential for practical
application
Porous Structure of Polymer Films Optimized by Rationally Tuning Phase Separation for Passive All-Day Radiative Cooling
Passive
all-day radiative cooling (PARC) films with porous structures
prepared via nonsolvent-induced phase separation (NIPS) have attracted
considerable attention owing to their cost-effectiveness and wide
applicability. The PARC performances of the films correlate with their
porous structures. However, the porous structure formed using the
NIPS process cannot be finely regulated. In this study, we prepared
polyvinylidene fluoride–hexafluoropropylene (PVDF–HFP)
films with porous structures optimized by rationally tuning the phase
separation, which was achieved by adjusting the proportions of two
good solvents with varying solubility parameters. The optimized PVDF–HFP
film with a hierarchically porous structure exhibited a high solar
reflectance of 97.7% and an infrared emissivity of 96.7%. The film
with excellent durability achieved an average subambient cooling temperature
of approximately 5.4 °C under a solar irradiance of 945 W·m–2 as well as a temperature of 11.2 °C at nighttime,
thus demonstrating all-day radiative cooling. The results indicate
that the proposed films present a promising platform for large-scale
applications in green building cooling and achieving carbon neutrality
Precise Distance Control and Functionality Adjustment of Frustrated Lewis Pairs in Metal–Organic Frameworks
We
report the construction of frustrated Lewis pairs (FLPs) in
a metal–organic framework (MOF), where both Lewis acid (LA)
and Lewis base (LB) are fixed to the backbone. The anchoring of a
tritopic organoboron linker as LA and a monotopic linker as LB to
separate metal oxide clusters in a tetrahedron geometry allows for
the precise control of distance between them. As the type of monotopic
LB linker varies, pyridine, phenol, aniline, and benzyl alcohol, a
series of 11 FLPs were constructed to give fixed distances of 7.1,
5.5, 5.4, and 4.8 Å, respectively, revealed by 11B–1H solid-state nuclear magnetic resonance spectroscopy. Keeping
LA and LB apart by a fixed distance makes it possible to investigate
the electrostatic effect by changing the functional groups in the
monotopic LB linker, while the LA counterpart remains unaffected.
This approach offers new chemical environments of the active site
for FLP-induced catalysis
