Table_2_Comparative analysis of KNOX genes and their expression patterns under various treatments in Dendrobium huoshanense.doc
IntroductionKNOX plays a pivotal role in governing plant growth, development, and responses to diverse abiotic and biotic stresses. However, information on the relationship between the KNOX gene family and expression levels under different treatments in Dendrobium is still limited.MethodsTo address this problem, we first used bioinformatics methods and revealed the presence of 19 KNOX genes distributed among 13 chromosomes in the Dendrobium huoshanense genome. Through an analysis of phylogenetic relationships, these genes were classified into three distinct clades: class I, class II, and class M. Our investigation included promoter analysis, revealing various cis-acting elements associated with hormones, growth and development, and abiotic stress responses. Additionally, qRT-PCR experiments were conducted to assess the expression patterns of DhKNOX genes under different treatments, including ABA, MeJA, SA, and drought.ResultsThe results demonstrated differential expression of DhKNOX genes in response to these treatments, thereby highlighting their potential roles in stress adaptation.DiscussionOverall, our results contribute important insights for further investigations into the functional characterization of the Dendrobium KNOX gene family, shedding light on their roles in plant development and stress responses.</p

Multiple Effects Promoting the Thermoelectric Performance of SnTe by Alloying with CuSbTe<sub>2</sub> and CuBiTe<sub>2</sub>
In
a SnTe-based thermoelectric material, the naturally high hole
concentration caused by cation vacancies and high total thermal conductivity
seriously hinder its thermoelectric performance. A recent work shows
that alloying SnTe with other compounds from the I–V–VI2 family (I = Ag, Na; V = Sb, Bi; VI = Te) can be considered
an effective strategy to boost the figure of merit efficiently via
the synergy of manipulating hole concentration and lowering lattice
thermal conductivity. Herein, we present a markedly enhanced thermoelectric
performance in p-type SnTe through CuPnTe2 (Pn = Sb, Bi)
alloying. Moreover, we found that the alloying with both CuSbTe2 and CuBiTe2 can facilitate the valence band convergence
of SnTe, but their relative influence is different. Interestingly,
compared to CuBiTe2, alloying with CuSbTe2 increases
the carrier concentration of SnTe, which suppresses the bipolar effect.
Ultimately, under the positive effect of valence band convergence,
increased vacancy concentration, and decreased lattice thermal conductivity,
compounds with a nominal composition of (SnTe)0.90(CuSbTe2)0.10 attains a peak zT of ∼1.26
at 823 K. In contrast, the thermoelectric performance of (SnTe)1–x(CuBiTe2)x is restricted by the reduced carrier concentration
and diminished band gap, showing only a humble maximum zT value of ∼0.91 at 823 K in the sample with a nominal composition
of (SnTe)0.96(CuBiTe2)0.04. These
results demonstrate the multiple effects on thermoelectric transport
during the formation of complex solid solutions
Nonflammable Electrolyte Based on Fluoroethylene Carbonate for High-Voltage LiCoO<sub>2</sub>/Si–Graphite Lithium-Ion Batteries
An electrolyte for high-voltage LiCoO2/Si–graphite
pouch cells is proposed in this work, which is composed of LiPF6 salt and fluoroethylene carbonate solvent as well as tris(trimethylsilyl)
phosphate and (ethoxy)pentafluorocyclotriphosphazene additives. Tris(trimethylsilyl)
phosphate additive plays a role in improving the interfacial properties
of electrodes, and (ethoxy)pentafluorocyclotriphosphazene additive
makes this electrolyte nonflammable. Its conductivity is as high as
5.48 mS cm–1 at 25 °C. This safe electrolyte
also enables the high-voltage LiCoO2/Si–graphite
pouch cells to obtain the ideal electrochemical performances. At room
temperature, the capacity retention reaches 81.7% after 200 cycles
at 1C, and the discharge capacity at 3C still retains about 77% of
the capacity at 1C. Furthermore, the interfacial properties of electrodes
are analyzed by scanning electron microscopy and X-ray photoelectron
spectroscopy measurements
Investigation of Temperature-Dependent Phonon Anharmonicity and Thermal Transport in SnS Single Crystals
Tin sulfide has outstanding thermoelectric properties
in the b-axis direction of crystallography as a IV–VI
group layered compound, which arouses great attention. In this study,
temperature-dependent Raman spectroscopy (TDRS) is used to quantify
the phonon anharmonicity in SnS crystals from 77 to 475 K, where the
three-phonon process dominates in this temperature region. Moreover,
integration of the four-phonon process and lattice thermal expansion
will better describe the temperature-dependent Raman experimental
phenomenon. The good agreement between the calculated and experimental
lattice thermal conductivity confirms the three-phonon scattering
process is the dominant scattering mechanism at this temperature range.
Further, combining the atomic thermal displacement and charge density
through density functional theory calculation, the inherently low
thermal conductivity of SnS is because of strong lattice anharmonicity,
which is brought by the presence of asymmetric chemical bonding resulting
from the Sn 5s2 lone pair electrons. These results provide
key insights for studying thermal properties of other low-dimensional
materials
