Table1_Multi-tissue transcriptome analysis to identify candidate genes associated with weight regulation in Hanwoo cattle.xlsx
While genetic markers related to meat production traits have been identified in many other cattle breeds, research on weight in Hanwoo cattle (Korean native cattle) is still insufficient. In this study, we performed expression quantitative trait loci (eQTL) analysis and differential gene expression analysis to detect candidate genes influencing the weight characteristics of 32 castrated Hanwoo cattle across 22 tissues and, we identified variants that affect gene expression levels. In total, we identified a total of 3,298 differentially expressed genes, among which we discovered key genes such as UBD, RGS2, FASN, and SCD that have functions related to adipogenesis, body weight, obesity, and lipid metabolism. Gene-set enrichment analysis revealed that candidate genes in adipose tissue are involved in metabolic pathways linked to obesity-related traits, adipose metabolism, and lipid metabolism. Additionally, we found that decreased expression of TRIM31 contributes to weight gain which can be explained by the associated candidate cis-eQTL genotypes for TRIM31 and their effect on differential gene expression between the lower and higher weight groups. Our findings revealed candidate genes associated with the weight of Hanwoo cattle and perhaps can provide comprehensive insights into the association of weight with various tissues beyond adipose tissue and muscle, indicating the potential for expanding the focus of livestock trait research.</p

Porous Perovskite-Type Lanthanum Cobaltite as Electrocatalysts toward Oxygen Evolution Reaction
Porous
lanthanum cobaltite (LaCoO<sub>3</sub>) was prepared by
hydrothermal reaction and converted into hollow nanospheres through
heat treatment. These hollow spheres were examined as electrocatalysts
toward oxygen evolution reaction (OER) using the rotating disk electrode
technique in an alkaline solution. The obtained mass-specific OER
activity was 7.51 A/g for porous LaCoO<sub>3</sub> particles and 12.58
A/g for hollow LaCoO<sub>3</sub> nanospheres at 1.60 V. These values
were more than 4–6 times higher than that of bulk LaCoO<sub>3</sub> compound (1.87 A/g). The OER performance of these perovskite-type
LaCoO<sub>3</sub> compounds was characterized using the Tafel equation,
which showed the hollow nanospheres had the fastest kinetics among
the three morphologies. The amorphous surface of these porous structures
could contribute to the enhanced OER performance. The electrocatalytic
and structural analysis results show the porous nanostructures with
amorphous surface layers are important to achieve high activity toward
OER for water splitting
Ca<sub>2</sub>Mn<sub>2</sub>O<sub>5</sub> as Oxygen-Deficient Perovskite Electrocatalyst for Oxygen Evolution Reaction
This paper presents the use of Ca<sub>2</sub>Mn<sub>2</sub>O<sub>5</sub> as an oxygen-deficient perovskite
electrocatalyst for oxygen
evolution reaction (OER) in alkaline media. Phase-pure Ca<sub>2</sub>Mn<sub>2</sub>O<sub>5</sub> was made under mild reaction temperatures
through a reductive annealing method. This oxygen deficient perovskite
can catalyze the generation of oxygen at ∼1.50 V versus (vs)
reversible hydrogen electrode (RHE) electrochemically, and reach an
OER mass activity of 30.1 A/g at 1.70 V (vs RHE). In comparison to
the perovskite CaMnO<sub>3</sub>, Ca<sub>2</sub>Mn<sub>2</sub>O<sub>5</sub> shows higher OER activities. The molecular level oxygen vacancies
and high spin electron configuration on manganese in the crystal structures
are likely the contributing factors for the enhanced performance.
This work demonstrates that oxygen-deficient perovskite, A<sub>2</sub>B<sub>2</sub>O<sub>5</sub>, is a new class of high performance electrocatalyst
for those reactions that involve active oxygen intermediates, such
as reduction of oxygen and OER in water splitting
Role of Graphene in Reducing Fatigue Damage in Cu/Gr Nanolayered Composite
Nanoscale
metal/graphene nanolayered composite is known to have ultrahigh
strength as the graphene effectively blocks dislocations from penetrating
through the metal/graphene interface. The same graphene interface,
which has a strong sp2 bonding, can simultaneously serve as an effective
interface for deflecting the fatigue cracks that are generated under
cyclic bendings. In this study, Cu/Gr composite with repeat layer
spacing of 100 nm was tested for bending fatigue at 1.6% and 3.1%
strain up to 1,000,000 cycles that showed for the first time a 5–6
times enhancement in fatigue resistance compared to the conventional
Cu thin film. Fatigue cracks that are generated within the Cu layer
were stopped by the graphene interface, which are evidenced by cross-sectional
scanning electron microscopy and transmission electron microscopy
images. Molecular dynamics simulations for uniaxial tension of Cu/Gr
showed limited accumulation of dislocations at the film/substrate
interface, which makes the fatigue crack formation and propagation
through thickness of the film difficult in this materials system
Wearable Electrocardiogram Monitor Using Carbon Nanotube Electronics and Color-Tunable Organic Light-Emitting Diodes
With
the rapid advances in wearable electronics, the research on
carbon-based and/or organic materials and devices has become increasingly
important, owing to their advantages in terms of cost, weight, and
mechanical deformability. Here, we report an effective material and
device design for an integrative wearable cardiac monitor based on
carbon nanotube (CNT) electronics and voltage-dependent color-tunable
organic light-emitting diodes (CTOLEDs). A p-MOS inverter based on
four CNT transistors allows high amplification and thereby successful
acquisition of the electrocardiogram (ECG) signals. In the CTOLEDs,
an ultrathin exciton block layer of bis[2-(diphenylphosphino)phenyl]ether
oxide is used to manipulate the balance of charges between two adjacent
emission layers, bis[2-(4,6-difluorophenyl)pyridinato-<i>C</i><sup>2</sup>,<i>N</i>](picolinato)iridium(III) and bis(2-phenylquinolyl-<i>N</i>,<i>C</i>(2′))iridium(acetylacetonate),
which thereby produces different colors with respect to applied voltages.
The ultrathin nature of the fabricated devices supports extreme wearability
and conformal integration of the sensor on human skin. The wearable
CTOLEDs integrated with CNT electronics are used to display human
ECG changes in real-time using tunable colors. These materials and
device strategies provide opportunities for next generation wearable
health indicators

Stretchable Heater Using Ligand-Exchanged Silver Nanowire Nanocomposite for Wearable Articular Thermotherapy
Thermal therapy is one of the most popular physiotherapies and it is particularly useful for treating joint injuries. Conventional devices adapted for thermal therapy including heat packs and wraps have often caused discomfort to their wearers because of their rigidity and heavy weight. In our study, we developed a soft, thin, and stretchable heater by using a nanocomposite of silver nanowires and a thermoplastic elastomer. A ligand exchange reaction enabled the formation of a highly conductive and homogeneous nanocomposite. By patterning the nanocomposite with serpentine-mesh structures, conformal lamination of devices on curvilinear joints and effective heat transfer even during motion were achieved. The combination of homogeneous conductive elastomer, stretchable design, and a custom-designed electronic band created a novel wearable system for long-term, continuous articular thermotherapy
Stretchable Carbon Nanotube Charge-Trap Floating-Gate Memory and Logic Devices for Wearable Electronics
Electronics for wearable applications require soft, flexible, and stretchable materials and designs to overcome the mechanical mismatch between the human body and devices. A key requirement for such wearable electronics is reliable operation with high performance and robustness during various deformations induced by motions. Here, we present materials and device design strategies for the core elements of wearable electronics, such as transistors, charge-trap floating-gate memory units, and various logic gates, with stretchable form factors. The use of semiconducting carbon nanotube networks designed for integration with charge traps and ultrathin dielectric layers meets the performance requirements as well as reliability, proven by detailed material and electrical characterizations using statistics. Serpentine interconnections and neutral mechanical plane layouts further enhance the deformability required for skin-based systems. Repetitive stretching tests and studies in mechanics corroborate the validity of the current approaches
