Ante cenário onde a agricultura é e será severamente afetada por alterações climáticas oriundas do aquecimento global, desponta a produção brasileira de café – relevante produto à economia do país –, que muito em breve pode ter sua capacidade produtiva seriamente impactada pelo clima. Como objetivos deste trabalho foram estabelecidos traçar um panorama perspectivo futuro à gestão da produção cafeeira nas principais regiões produtoras do Brasil ante cenário de alterações do clima; compreender os principais desafios apresentados à cafeicultura sob uma perspectiva de condições ambientais influenciadas pelas alterações climáticas; propor medidas adaptativas capazes de serem adotadas pelos cafeicultores para mitigação dos impactos negativos dos principais desafios oriundos do processo de alterações climáticas, visando favorecer a salvaguarda da segurança alimentar no país. O arcabouço metodológico adotado foi a pesquisa quali-quantitativa de natureza básica e caráter exploratório, por meio da revisão bibliográfica e documental. Como principais resultados previu-se que o zoneamento de áreas aptas ao cultivo do café deverá ser reduzido drasticamente nos anos vindouros, sendo as regiões produtoras do grão direcionadas a restritas áreas montanhosas e de largas latitudes, o que reduziria a capacidade produtiva do setor e majoraria o preço do produto no mercado, conjuntura que, possivelmente, agravaria a questão de insegurança alimentar no país. A vista disso, foi desenvolvido um guia com medidas adaptativas a serem adotadas pelos cafeicultores na mitigação de impactos negativos oriundos das alterações climáticas. Por fim, concluiu-se que além de ser lucrativo produto agrícola à economia do país, o café se apresenta como um dos alimentos mais frequentemente consumido pelo brasileiro, promovendo quaisquer eventos que possam vir a prejudicar sua produção a questão de primeira atenção em relação à segurança alimentar nacional.

Published: August 2023

Aims: This study aimed to determine the effect of additional filtration on the image quality and dose reduction in pelvic radiographic examinations.

Study Design:  Mention the design of the study here.

Place and Duration of Study: The research was conducted at a municipal emergency service radiology department in Rio Grande do Sul, Brazil.

Methodology: Using a simulator object to replicate clinical examination conditions. The radiographic equipment was fitted with aluminum, copper, and copper-aluminum composition filters to identify the optimal filtration for reducing radiation doses and maintaining image quality.

Results: Results showed that filtration effectively reduced dose and average absorbed dose in internal organs, with the greatest reduction observed with the copper filter. However, excessive filtration resulted in a decrease in image quality, particularly with the copper filter. The Figure of Merit (FOM) demonstrated that keeping the electrical factors of the X-ray tube consistent (70 kVp and 32 mAs) and using an additional 2.5 mmAl filter could optimize pelvic radiographic examinations, based on the diagnostic IQ criteria established by the service.

Conclusion: In conclusion, the FOM revealed that using additional filtration of 2.5 mmAl and maintaining the X-ray tube's electrical factors at 70 kVp and 32 mAs could reduce the KERMA in air by 49.8% in the patient, 41.5% in the testes, 35.5% in the bladder, 30.4% in the ovaries, 29.7% in the bone marrow, and 35.3% in the total effective dose of the examination, while maintaining equivalent image quality.

Major grain-producing countries such as Canada, the United States of America, Mexico, Brazil, Australia, China, India, Turkey, and Russia, in the direction of selection for the creation of new varieties of wheat resistant to abiotic factors, are paying great attention to creating new wheat varieties by developing new genotypes by identifying donors with high-quality and positive indicators of valuable economic traits and introducing them into modern selection methods. Progress has been made in this direction worldwide. Today, many varieties of wheat with valuable economic traits and high grain quality have been created and introduced to large areas. In this study, 23 genotypes were selected from 45 genotypes of bread wheat varieties and lines. The nursery’s growth period lasted between 233-238 days, and the lines appeared more mature than the local check varieties. Compared to the local check varieties, among the plant’s biometric indicators, 15 lines showed positive results in terms of plant height, 10 lines in peduncle length, 5 lines in spike length, 1 line in spike number, and 1 line in resistance to lodging. The statistical analysis of grain yield and grain quality using the Dospekhov method  showed that the experimental error rates for various indices as follows: 0.888% for yield, 3.018% for weight of 1000 grains, 0.627% for Test weight, 2.028% for protein content, 1.519% for gluten content, 2.001% for IDK, and 4.01% for grain glassiness. It was noted that the experiment was conducted correctly in terms of repetitions and showed a positive result. 10 genotypes with yield of genotypes 72.6-96.7 c/ha, weight of 1000 grains 37.9-43.2 g, test weight 803-835 g/l, protein content 16.2-19.3%, gluten content 28.5-30.4% were selected. Accordingly, it was observed that the amount of iron was 1.0-1.8 mg. It was observed that the sample was 1.3 mg in the Gozgon variety and 1.4 mg in the Antonina variety. KR20-27-FAWIR-67, KR20-BWF5IR-2625, KR20-27-FAWIR-138 lines 1.6 mg relative to the local check variety. Lines KR20-BWF5IR-2460, KR20-27-FAWIR-39, KR20-BWF5IR-246 1.7 mg. It was observed that the KR20-27-FAWIR-154 line showed a high result of 1.8 mg.

The study appraised government recurrent expenditure pre- and post-Integrated Personnel Payroll Information System implementation in Nigeria. Government recurrent expenditure on general administration, government recurrent expenditure on education, government recurrent expenditure on defence, and government recurrent expenditure on health, formed the dependent variables of the study. The study adopted an ex-post-facto research design, covering the period between 1995 and 2019. Secondary data were extracted from the Central Bank of Nigeria Statistical Bulletin. Paired Sample T-test technique was used for the data analysis. In line with the specific objectives of the study which was to appraise the difference in the mean of government recurrent expenditure on general administration, education, defence, and health pre and post Integrated Personnel and Payroll Information System implementation in Nigeria, it was revealed that all the recurrent expenditures studied have a positive and significant difference in mean after IPPIS implementation in Nigeria. This implies that IPPIS has not been able to cutdown government recurrent expenditure in Nigeria. It is recommended therefore that the federal government should adequately monitor and utilize the money saved from recurrent expenditure due to implementation of IPPIS. They should employ more administrative staff using the money saved from eradicated ghost workers. The government should consider an upward review of the educational budget to meet up with the 26% allocation recommended by UNESCO and above. The government should monitor how the huge amount of money spent on defence was appropriated. This will help in preventing and stamping out corruption. An encompassing stakeholders’ forum in the Nigerian health sector remain essential. The national health system needs a solid administrative policy foundation that allows coordination of priorities and partnerships in the health workforce and among various stakeholders. This will help stamp out embezzlement and corruption in the system.

Published: August 2023

The efforts of the firm in anticipating the increasing trend of fierce competition recently is to apply proper marketing strategies, and one of such strategies is so called marketing mix strategy. As a result of proper marketing mix strategy implementation, once customer satisfaction greatly influences purchasing decisions, it will create the opportunities for customers to make subsequent purchases. Through a literature study, this study finds that there are many studies explain the role of marketing mix on customer satisfaction. Nevertheless, this study finds that there are lesser prior studies explain the mediating role of brand image on the relationship of marketing mix and customer satisfaction. Additionally, for the novelty of this study, many studies have been conducted in explaining the role marketing mix on customer satisfaction, however, such studies only focus on the Western countries, and lack of prior studies have been highlighted on the Asian region, especially within the developing countries. This study then intends to conduct an investigation that mainly focuses on the mediating role of brand image on the relationship between distribution, price, and promotion, and customer satisfaction. As a research novelty and theoretical contribution of this study, interestingly, this study finds that brand image becomes one of critical factor in influencing customer satisfaction, whereas, distribution, price, and promotion have no significant impact on customer satisfaction. For managerial contribution, this study elaborates in the particular sections of this paper.

These were statistically significant in the differences of VAS of uterine contractile pain at 8h and 12 h after surgery (P < 0.05), in which the VAS in PMD group were lower than that in PD group and MD group, and in which the VAS in PD group was lower than that in MD group. The time of starting to get out of bed after surgery was earlier in the PMD group than in the PD and MD groups (P < 0.05). The number of steps taken by mothers within 2 days after surgery was higher in the PMD group than in the PD and MD groups (P < 0.05). The step count within two days post-surgery was higher in the PMD group than in the PD and MD groups (P < 0.05). The serum substance P levels at the end of surgery and 1 day after surgery were lower in the PMD and PD groups than in the MD group (P < 0.05). The differences in the number of breastfeeding times within two days after surgery were statistically significant among the three groups (P < 0.05), with that in the PMD group（16.27±2.71) having been higher than in the PD group（12.63±1.67）and MD group（11.03±1.81), and that in the MD group being higher than in the PD group.

Conclusion: The single intravenous sodium parecoxib combined with single epidural morphine and dezocine intravenous analgesia can better reduce the incision pain and uterine contractile pain after cesarean section, promote maternal postoperative off-bed activity and breast-feeding  times to newborn.

Published: August 2023

Soil erosion poses a significant environmental challenge worldwide, causing the depletion of fertile topsoil, reduced crop productivity, and heightened sedimentation in water bodies. The extent of erosion depends on factors such as rainfall intensity, land slope, soil type, land use, and management practices. Accurate assessment of soil loss, considering spatial, temporal, and climate change factors, is vital for effective soil and water conservation planning. In this study, a spatial model for estimating soil loss was developed by integrating GIS with the Revised Universal Soil Loss Equation (RUSLE), and validation showed satisfactory results (R2=0.82). The spatial estimation revealed that most of the area experienced soil loss below 5 t ha-1 yr-1, with only a smaller portion showing soil loss exceeding 20 t ha-1 yr-1. To address this, in-situ soil conservation measures are recommended, such as using erosion-resistant crops (e.g., groundnut) in strip cropping, adopting crop rotations, mulching, and planting grasses for bund stabilization. Practices like deep ploughing, summer ploughing, and mixed cropping should also be adopted for sustainable watershed management. Construction of conservation structures like farm ponds and percolation tanks is highly recommended. The study also observed temporal variations in soil loss for Sangareddy district, with the highest soil loss of 134 t ha−1 yr−1 occurring in 2020, and the lowest of 71 t ha−1 yr−1 in 2018. These findings underscore the need for continuous monitoring and adaptive conservation strategies to mitigate soil erosion and ensure sustainable land use practices in the region.

There are several short- and long-term negative effects on human health caused by the well-known pollutant known as particulate matter (PM), which also significantly contributes to urban air pollution. Trees can act as a sustainable air purifying filter by adsorbing and absorbing tiny airborne dust. Their effectiveness is influenced by a number of variables, including particulate matter concentration and leaf features of tree species. In this study, the particulate matter capturing capacity of commonly grown 20 tree species were compared and the best tree species were chosen for the urban plantation to reduce particulate matter pollution. In this study, Ficus bengalensis (0.67 mg/cm2), Mangifera indica (0.61 mg/cm2), Polyalthia longifolia (0.57 mg/cm2), Tectona grandis (0.66 mg/cm2) and Terminalia catappa (0.63 mg/cm2) were found to be the best tree species among the 20 tree species and also it was confirmed that morphological characteristics of tree leaves plays an important role in capturing the particulate matter from the atmosphere. In conclusion, our findings may help in the selection of greening tree species with strong particulate matter purifying capacities for both industrial and urban areas.

Background: Endometriosis and periodontitis are chronic and inflammatory diseases. Studies, assumptions and opinions try to shed light on this possible relationship. The aim of this systematic review was to investigate the association between endometriosis and periodontal disease.

Methods: The following databases: Medline, Scopus, Embase, Web of Science, Cochrane Library, and Goolge Scholar, the descriptors used were: Endometriosis and Periodontal Disease in English, during the period from 1995 to 2023. 10 abstracts were found that had submitted the entire article for inclusion analysis. The eligibility criteria were: clinical trials, observational studies, and specific studies of endometriosis with periodontal diagnosis. Case reports, laboratory studies, and studies without periodontal disease in participants were excluded. Abstracts were evaluated by two investigators.

Results: After accepting the eligibility criteria, two studies were included in this review, a cross-sectional study and a case-control study. The included studies do not allow for comparison, have different periodontal diagnostic criteria, and focus more on the biological plausibility of the increase in circulating cytokines in the body than on the observed outcomes.

Conclusion: Nowadays there is no association between endometriosis and periodontal diseases, the studies only indicate a biological plausibility, clinical studies with adequate methodological design are necessary to prove such an association.

In this work, an alternative fabrication process is implemented to fabricate a bioresorbable Na‐ion battery showing excellent electrochemical performance (discharge capacity of 5.1 mAh cm−2) and no toxicity after being disintegrated under in vivo conditions. Solely composed of biocompatible materials, the proposed all‐solid‐state rechargeable battery implanted under the skin is capable of disintegrating safely. The operating days and lifetime of this novel energy storage system are evidenced that after being implanted in artificial skin can be finely controlled by tuning the thickness of the encapsulation layer, rendering possible the design of “on‐demand” bio‐eliminable batteries that may operate days or several weeks. The toxicity tests and the lack of organ damage performed by ex vivo analyses after 3 months confirmed the safety of the approach. In addition, wireless recharge of the battery is demonstrated through the skin using an inductive charger to establish the proof‐of‐concept. Preliminary tests revealed that wireless recharge of the subcutaneous implanted battery is achieved in 30 min, and that recharge remains possible in 1 h for deeper implanted batteries. The high versatility of the concept is definitely appealing to address the various needs of the temporary medical device market.

Published: January 2025

Disparities in surface energy and mechanical properties present significant challenges to the integration of soft tissues with medical devices. Inspired by the natural sealing structure of the junctional epithelium in teeth, a universal dual‐layer adhesive patch that can immediately bridge contrasting interfaces between soft tissue and devices is developed. This structure comprises a semicrystalline elastomer layer with adjustable stiffness and adhesion, paired with a hydrogel layer that ensures strong tissue adhesion. Before implantation, the semicrystalline elastomer maintains a high modulus and nonadhesive properties, facilitating ease of application. Once implanted, body temperature induces melting of the crystalline region, triggering a decreased modulus and enhanced conformal adhesion to various device materials. The hydrogel layer further promotes adhesion to moist soft tissues through water absorption and chemical bonding, effectively sealing both sides of the interface. The interpenetration and cross‐linking between these two layers prevent delamination and overexpansion in humid environments, enhancing the overall performance and reliability of the adhesive patch. The universal sealing and adhesion efficacy is validated in different simulated clinical situations including denture retention, drainage tube fixation, and peri‐implantitis prevention. Therefore, the Janus adhesive patch for temporary immediate soft tissue‐device integration shows promising potential for a wide range of clinical applications.

Published: January 2025

Zinc‐iodine (Zn‐I2) batteries are deemed as promising next‐generation energy storage devices in view of immanent security and high capacity. Nevertheless, their applications are deteriorated by unruly dendritic Zn growth, severe polyiodide diffusion, and sluggish iodine redox kinetics. Herein, MXene‐mediated Janus separators with heterogeneous double‐sided interfaces are designed to simultaneously manipulate Zn deposition and accelerate iodine adsorption‐conversion kinetics. The anode side is composed of zincophilic Cu‐modified hollow MXene spheres, which not only decreases Zn nucleation energy barrier but also suppresses Zn dendrite growth by homogenizing electric field distribution and inducing oriented aspectant dendrite‐free Zn growth between the separator and anode. While the cathode side, consisting of iodophilic Co‐modified hollow N‐doped MXene spheres, inhibits the polyiodide shuttling and promotes iodine electrocatalytic conversion through Co‐N‐C sites. Such an ingenious engineering of Janus separators achieves a durable circulation over 2900 h for Zn||Zn symmetric cells and brings about an ultrahigh capacity of 274 mAh g−1 for Zn‐I2 batteries as well as an ignorable decay (0.001% per circle) after 20 000 cycles. The concept of Janus separator design by integrating interfacial chemistry regulation and physical structure optimization in this work provides inspiration for constructing advanced energy storage devices with exceptional overall performance.

Published: January 2025

The direct dehydrogenation of alkanes to olefins under mild conditions is challenging due to the inert nature of alkyl C─H bonds. Herein, an efficient photocatalytic system is developed for propane direct dehydrogenation (PDH) to propylene, consisting of ≈1.30 nm sized PtO2 clusters immobilized on a layered double hydroxide ‐derived ZnO/Al2O3 support (LD‐Ptn). Under UV excitation (365 nm), photogenerated holes in ZnO migrate to Pt sites at PtO2/ZnO interfaces, thereby activating and dissociating C─H bonds in propane. A propylene production rate of almost 1 mmol g−1 h−1 and a nearly 100% selectivity are achieved for the compositionally optimized LD‐Ptn photocatalyst. Control experiments and density functional theory calculations further verify that the excellent photocatalytic PDH performance of LD‐Ptn stems from synergism between ZnO semiconductor and the loaded Pt species. This work identifies a promising new route for direct production of olefins from alkanes.

In silico Comparative Study of the Anti‐Cancer Potential of Inhibitors of Glucose‐6‐Phosphate Dehydrogenase Enzyme Using ADMET Analysis, Molecular Docking, and Molecular Dynamic Simulation
Authors: Tepap Zemnou Cromwel
Published: January 2025

Cancer is marked by the rapid, unregulated growth and division of abnormal cells, often overwhelming healthy cells and compromising normal function. Given the limitations of current therapies, there is an urgent demand for novel drugs. The enzyme glucose‐6‐phosphate dehydrogenase (G6PD), essential to the pentose phosphate pathway (PPP) and frequently associated with cancer cell metabolism, presents a promising target for cancer treatment. However, no G6PD inhibitor is yet validated as an approved drug. This study focuses on the in silico assessment and comparative analysis of the anticancer potential of five G6PD inhibitors: glucose‐6‐phosphate dehydrogenase inhibitor 1 (G6PDi1), 3alpha,21‐Dihydroxy‐5alpha‐pregnant‐20‐one (THDOC), dehydroepiandrosterone (DHEA), 6‐aminonicotinamide (6‐AN), and polydatin (PD). Molecular docking results show that G6PDi1 exhibits the highest binding affinity (−8.65 kcal mol−1) among the inhibitors tested. ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) pharmacokinetics, and biological activity assessments identified PD, THDOC, and G6PDi1 as the most promising G6PD inhibitors. Furthermore, a 100 ns molecular dynamics (MD) simulation combined with Molecular Mechanics/Poisson‐Boltzmann surface (MM‐PBSA) post‐simulation analysis indicated stability and compactness for all compounds, with no significant deviations observed throughout the simulation period. These findings suggest THDOC and G6PDi1 as potential candidates for developing effective cancer therapeutics targeting G6PD.

In recent years, the development of ferroaluminum (FeAl) alloy materials in the industrial world increases rapidly. However, the influence of various conditions on the fabrication process remains underexplored. This study investigates the effect of pressure on the solidification process of FeAl alloy materials. A new indication of material characteristics at the atomic level is proposed using molecular dynamics simulations. The embedded atom method (EAM) is also investigated by comparison with experimental results. The results indicate that the pressure during the solidification process plays a significant role in the formation of the local structure of FeAl material. The results also suggest that the pressure has a major influence on the increasing intensity of the first peak in the radial distribution function g(r) and structure factor S(q), with increases of 32.71% and 33.39% at 40 GPa compared to 0 GPa, respectively.

Sodium‐metal batteries are the most promising low‐cost and high‐energy‐density new energy storage technology. However, the sodium‐metal anode has poor reversibility, which can be optimized by constructing the robust solid electrolyte interphase (SEI). Here, a concept of dual‐weak‐interaction electrolyte (DWIE) is demonstrated, its double‐layer solvation structure is composed of weakly solvated tetrahydrofuran as the inner layer, and dipole interaction are introduced in the outer layer by dibutyl ether. This double‐layer solvation structure dominated by contact ion pairs and aggregates can promote to deriving of inorganic‐rich SEI film, resulting in smooth and dendrite‐free sodium‐metal deposition. By adjusting the molecular configuration of dibutyl ether to diisobutyl ether, the dipole interaction is further enhanced, resulting in stronger weakly solvating effect. Thus, the Na||Cu cells using the optimized DWIE achieved a high Coulombic efficiency of 99.22%, surpassing most electrolyte design strategies. Meanwhile, at 5C, the Na3V2(PO4)3 (NVP)||Na cell achieves stable cycling exceeding 3000 cycles. Even under rigorous conditions of ≈8.8 mg cm−2 NVP loading and 50 µm thickness Na, the full cell can achieve a long cycling lifespan of 217 cycles. The pioneering concept paves the way for crafting readily achievable, cost‐effective, and eco‐friendly electrolytes tailored for SMBs, and offers potential applications in other battery systems.
Investigating the Multifunctional Role of Tris(trimethylsilyl)phosphite as an Electrolyte Additive via Operando Gas Chromatography/Mass Spectrometry and X‐ray Photoelectron Spectroscopy

Published: January 2025

The multifunctional electrolyte additive tris(trimethylsilyl)phosphite (TMSP) is investigated with a combination of operando gas chromatography/mass spectrometry and X‐ray photoelectron spectroscopy techniques, supported by cycling experiments and electrochemical impedance spectroscopy (EIS) measurements. Indications for hydrofluoric acid (HF) scavenging by TMSP could be found in the gas phase as well as on the electrode surfaces; however, it is observed that the use of TMSP leads to the production of HF, which it eventually scavenges. The investigation of the interphase formation shows that the decomposition products of TMSP are integrated into the interphases of both electrodes. This is accompanied by the formation of trimethylsilane as a decomposition product in the gas phase. TMSP also promotes the two‐electron reduction of ethylene carbonate (EC), which is deduced both from an increased amount of ethene in the gas phase and from Li2CO3 on the electrode surface. The electrochemical investigations show that cells with TMSP have a lower interphase resistance after continued cycling. However, only the cells with 1 wt% of TMSP in the electrolyte outperform the TMSP‐free reference cells. It is concluded that adding more than 1 wt% of TMSP increases the parasitic reactions of the additive to an extent that it partially counteracts its beneficial effect.

This study measured 17 surface water quality (WQ) parameters in a 731 ha Conservation Effects Assessment Project watershed, Beasley Lake, in Mississippi, under varying flooding conditions from 2008 to 2022. To assess flooding impacts on lake WQ, data from before and after flood events were compared among three flood‐stage categories: minor flooding at 30.95 m mean sea level (MSL), 99.1 ha of the watershed inundated affecting 27.9 ha under conservation practices (CPs); moderate flooding at 32.17 m MSL, 235.1 ha of the watershed inundated affecting 69.2 ha under CPs; and major flooding at 32.78 m MSL, 331.8 ha of the watershed inundated affecting 87.0 ha under CPs. During minor flood events, only nitrite significantly increased (82%; p < 0.05) from pre‐ to post‐flood conditions. For moderate flood events, dissolved solids decreased 21%, whereas suspended solids increased 259%, and most nutrients increased from 33% to 199% (ammonium) except nitrate and N:P ratios. With major flooding, dissolved solids also decreased 22% and suspended solids increased 237%, with increased phosphorus from 25% to 164% (orthophosphate) and decreased N:P (36%). Correlation analysis showed greater flood duration (in days) and magnitude (as river stage) increased suspended solids and nutrient concentrations. Weaker relationships were observed with watershed and CP area inundation and WQ. Results will provide landowners and action agencies with predictive changes in WQ parameters based on flooding stage and potential impositions of effects through watershed areas that coincide with CPs.

The suckers on the octopus arm play a pivotal role in the execution of tasks in unstructured environments by providing a means to grip objects as well as perceive the environment through (chemo‐)tactile receptors in the suckers. This work presents an octopus‐inspired suction cup with high‐resolution tactile sensing capabilities using a camera that captures the displacement of markers that are integrated in the suction cup. The orientation of the suction cup with respect to an object surface could be predicted with an average error of 1.97° for latitude and 9.41° for longitude. In a closed‐loop control experiment, the orientation of the suction cup with respect to the object surface is estimated by an initial touch and the suction cup is consequently reoriented to approach the object surface in a perpendicular manner. The passive compliance of the suction cup is sufficient to compensate for the prediction error and a seal could be created on all of the objects. In combination with the automated design and manufacturing process, this is a major step toward the deployment of sensory innervated suction cups for motion planning and control of soft continuum robot arms.

Enriching the structural diversity of metal–organic frameworks (MOFs) is of great importance in developing functional porous materials with specific properties. New MOF structures can be accessed through the rational design of organic linkers with diverse geometric conformations, and their structural complexity can be enhanced by choosing linkers with reduced symmetry. Herein, a series of Zr‐based MOFs with unprecedented topologies were developed through a linker desymmetrization and conformation engineering approach. A tritopic carboxylate linker with reduced symmetry and flexible triangular geometry was designed to construct three Zr‐based MOFs (denoted as NU‐57, NU‐58, and NU‐59) by modulating synthetic conditions. Notably, the conformational flexibility and reduced symmetry of the linker generated two unprecedented topologies in NU‐58 and NU‐59. Furthermore, solvent removal in NU‐58 via thermal activation process produced missing linker defects. Finally, the adsorption behavior of these MOFs toward alkanes and alkenes was studied to gain insights into their structure–property relationships, which demonstrated that NU‐57 and NU‐58 exhibit unusual reverse selectivity for alkanes in alkane/alkene separations. Overall, this work highlights the rational design of linkers using a desymmetrization strategy as a powerful method to enrich the structural diversity of MOFs and to access novel MOFs with unique properties.

The increasing power and integration of electronic devices have intensified serious heat accumulation, driving the demand for higher intrinsic thermal conductivity in thermal interface materials, such as polydimethylsiloxane (PDMS). Grafting mesogens onto PDMS can enhance its intrinsic thermal conductivity. However, the high stability of the PDMS chain limits the grafting density of mesogens, restricting the improvement in thermal conductivity. This work proposes a new strategy to efficiently introduce mesogens onto PDMS through ring‐opening copolymerization of liquid crystal cyclosiloxane and octamethylcyclotetrasiloxane, enhancing the grafting density. The relationship between the grafting density and intrinsic thermal conductivity of liquid crystal polydimethylsiloxane (LC‐PDMS) is investigated by nonequilibrium molecular dynamics (NEMD) simulations. Based on the simulation results, LC‐PDMS with enhanced intrinsic thermal conductivity is synthesized. When the grafting density of mesogens reaches 77.4%, its intrinsic thermal conductivity coefficient (λ) increases to 0.56 W/(m·K), showing a 180.0% improvement over ordinary PDMS (0.20 W/(m·K)). The LC‐PDMS also exhibits the low dielectric constant (ε, 2.69), low dielectric loss tangent (tanδ, 0.0027), high insulation performance (volume resistivity, 3.51×1013 Ω·cm), excellent thermal stability (heat resistance index, 217.8℃) and excellent hydrophobicity (water contact angle, 137.4°), fulfilling the comprehensive requirements of advanced thermal interface materials.
