AbstractBlackbody‐sensitive uncooled infrared photodetectors with ultra‐broadband and ultrafast photoresponse have a profound impact on many areas of modern science and technology. However, it is a big challenge for both traditional photodetectors and emerging low‐dimensional ones to simultaneously have all the above characteristics. Here, this challenge is addressed by establishing a Te/WTe2 heterostructure photodetector. The built‐in field of the heterostructure and the crossing conduction and valence bands of WTe2 jointly result in a high responsivity and a visible‐to‐long‐wavelength‐infrared photoresponse range. The peak responsivity (at the 3.3 µm wavelength) reaches 914 mA W−1 at zero bias and 8.51 A W−1 at 2 V bias. Further, the joint action coupled with the high mobility of Te and WTe2 promotes the 3‐dB bandwidth to 153 kHz. The self‐powered blackbody responsivity and specific detectivity reach 235.7 mA W−1 and 1.1 × 108 cm Hz1/2 W−1, respectively. The former increases to 5.82 A W−1 at 1 V bias. Moreover, this device is polarization‐sensitive with a contrast ratio of 2. This work reveals the potential of the Te/WTe2 heterostructure for high‐performance room‐temperature infrared photodetectors.

AbstractNonlinear optical (NLO) crystals that have the capability of achieving tunable lasers through frequency conversion are of great importance in solid‐state lasers. Herein, three new deep‐UV transparent alkali‐scandium sulfates with strong second‐harmonic generation (SHG) response and high thermal stability, A3Sc(SO4)3 (A = K, Rb, Cs), are successfully obtained. It is interesting that the slightly distorted [ScO6] octahedrons are in an ordered/oriented arrangement, which is in favor of the generation of SHG response. Especially, K3Sc(SO4)3 not only exhibits a strong phase‐matching SHG response of 1.6 × KDP, a short deep‐ultraviolet (deep‐UV) cutoff edge of 190 nm, a wide transparent window covering from the deep‐UV region to mid IR, a high laser‐induced damage threshold of 165 MW cm−2 and easy growth of large single crystal, but also behaves thermal stable up to 900 °C under an air atmosphere. Crystal structures and theoretical calculations reveal that their strong SHG responses mainly stem from the slightly distorted [ScO6] octahedron. This study highlights A3Sc(SO4)3 (A = K, Rb, Cs) as promising deep‐UV transparent NLO crystals and offers a new approach for the pursuit of high‐performance NLO crystals.

AbstractThe advent of molecularly targeted therapeutics has transformed the management of patients with acute myeloid leukemia (AML). Particularly for individuals unfit for intensive chemotherapy, lower intensity therapies (LIT) incorporating small molecules have significantly improved patient outcomes. With BCL2, IDH1, IDH2, and FLT3 inhibitors widely used for relapsed AML, combination regimens are now utilized in the frontline. Expansion of these targeted LIT combinations, along with development of novel agents including menin inhibitors, exemplifies the promise of precision medicine. Further understanding of molecular drivers of leukemic transformation and mechanisms of relapse will continue to advance frontline treatment options for patients with AML.

AbstractIntroductionLocomotion activities are part of most human daily tasks and are the basis for subsistence activities, particularly for hunter–gatherers. Therefore, differences in speed walking‐related variables may have an effect, not only on the mobility of the group, but also on its composition. Some anthropometric parameters related to body length could affect walking speed‐related variables and contribute to different human behaviors. However, there is currently little information on the influence of these parameters in nonadult individuals.MethodsOverall, 11 females and 17 male child/adolescents, 8–17 years of age, volunteered to participate in this cross‐sectional study. Five different pace walking tests were performed on a treadmill to calculate the optimal locomotion speed (OLS) and U‐shaped relationship between the walking energy expenditure and speed (χ2 cost of transport [CoT]) (i.e., energetic walking flexibility).ResultsThe mean OLS was 3.05 ± 0.13 miles per hour (mph), with no differences between sexes. Similarly, there were no sex differences in walking flexibility according to the χ2 CoT. Body height (p < .0001) and femur length (p < .001) were positively correlated with χ2 CoT; however, female child/adolescents mitigated the effect of height and femur length when walking at suboptimal speeds.ConclusionConsistent with prior observations in adults, our findings suggest that anthropometric parameters related to body stature are associated with reduced suboptimal walking flexibility in children and adolescents. Taken together, these results suggest that children and adolescents can adapt their pace to the one of taller individuals without a highly energetic penalty, but this flexibility decreases with increasing body size.

Published: July 2024

AbstractFused polycyclic aromatic compounds containing carbazole and diazapyrene skeletons as electron donors and acceptors, respectively, were synthesized in a few steps from readily accessible starting materials. The incorporation of diazapyrene units into the polycyclic compounds resulted in significant bathochromic shifts in their absorption and emission bands compared to those of the corresponding carbazole derivatives. Electrochemical measurements and density functional theory calculations were performed to gain further insight into their electronic properties. Our findings demonstrate that the incorporation of nitrogen atoms and substituents, as well as the different topologies of the fused‐ring system, exert a profound effect on the electronic properties of the polycyclic compounds.

AbstractRechargeable Mg batteries are a promising energy storage technology to overcome the limitations inherent to Li ion batteries. A critical challenge in advancing Mg batteries is the lack of suitable cathode materials. In this work, we report a cathode design that incorporates S functionality into two‐dimensional metal‐organic‐frameworks (2D‐MOFs). This new cathode material enables good Mg2+ storage capacity and outstanding cyclability. It was found that upon the initial Mg2+ insertion and disinsertion, there is an apparent structural transformation that crumbles the layered 2D framework, leading to amorphization. The resulting material serves as the active material to host Mg2+ through reduction and/or oxidation of S and, to a limited extent, O. The reversible nature of S and O redox chemistry was confirmed by spectroscopic characterizations and validated by density functional calculations. Importantly, during the Mg2+ insertion and disinsertion process, the 2D nature of the framework was maintained, which plays a key role in enabling the high reversibility of the MOF cathode.

AbstractSesame (Sesamum indicum L.) is renowned for its significance as a global oilseed crop, valued for its high oil content and nutritional properties. This study aimed to explore the fatty acid composition, bioactive compounds, and antioxidant attributes of sesame mutant oils, examining their potential applications in food industry. Nine M4 mutants, along with their parents, were grown in two contrasting environments (Taoujdate and Afourare) to investigate their seed oil, phenolic and flavonoid contents, the balance between omega‐6, omega‐9, and omega‐3 fatty acids, iodine value, and susceptibility to oxidation. Genotype and environment main effects as well as their interaction had a significant effect on the majority of the parameters studied. The mutant “US2‐1” stands out with a distinctive fatty acid profile, featuring the highest saturated fatty acids, ω‐6/ω‐9 ratio, and omega‐3 content, in addition to its high total flavonoid content and remarkable oxidative stability. “ML2‐10,” “US1‐2,” “US2‐6,” and “US2‐7” exhibit high oil content, coupled with substantial levels of phenols and flavonoids, rendering them excellent candidates for culinary and industrial applications where oxidative stability is important. “ML2‐68,” “ML2‐72,” “US06,” “US1‐DL,” and “US1‐3” offer versatile options with their moderate oil content and fatty acid profiles that resist oxidation. This research highlights the potential for breeding sesame mutants tailored to specific applications, contributing to both enhanced oil production and improved nutritional value. The insights gained here pave the way for the development of sesame varieties with superior nutritional and functional attributes, thereby promoting the sustainable production and consumption of sesame oil.
A latent curing agent for rapid curing of phenolic epoxy resin at low temperature
Authors: Guo Jian‐Qiao , Zhang Xing‐Hong 
Published: July 2024

AbstractDeveloping effective latent curing agent for rapid curing of epoxy resins at low temperatures remains challenging. This study reports a latent curing agent, ortho‐cresol phenolic epoxy resin‐bisphenol A (EOCN‐BPA), prepared through the addition reaction of o‐methyl phenolic epoxy resin with BPA. When blended with dicyandiamide (DICY) in a 1:3 molar ratio, EOCN‐BPA/DICY is used to cure a linear epoxy phenolic novolac (EPN) resin (epoxy equivalent: 550 g eq−1, softening point: approximately 82°C), at an onset curing temperature of 90°C, which is considerably lower than the onset curing temperature of DICY with EPN (160°C). However, EOCN‐BPA does not react with EPN without a catalyst. Therefore, this latent curing system is successfully applied in powder coatings, rapid curing at 120°C within 3 min without an additional catalyst, outperforming the EPN/EOCN‐BPA system using cocatalyst 2‐methylimidazole. Consequently, DICY catalyzes the curing reaction between the phenol hydroxyl group and epoxy resin and participates in it. The prepared powder coating exhibits excellent storage stability, maintaining its properties for over 3 months at room temperature. These findings demonstrate the excellent latent properties of EOCN‐BPA/DICY, highlighting its potential as a highly effective latent curing agent.

AbstractVarious electrospun fibrous membranes have been addressed for oil/water separation owing to their advantages of high specific surface ratio, lightweight, and high porosity. However, they are commonly obtained by solution electrospinning of non‐green raw materials, which could cause serious environmental issues. To realize effective oil/water separation, the optimal processing parameters for melt electrospun polylactic acid (PLA) were determined through orthogonal experiments. Subsequently, PLA fibrous films with cellulose nanofiber (CNF) or sodium chloride (NaCl) for oil/water separation were produced via melt electrospinning. The effects of incorporating CNF or NaCl on the physiochemical properties of melt electrospun PLA fibrous membranes were investigated. In contrast to the pure PLA membranes, the obtained PLA/CNF and PLA/NaCl composite membranes exhibit a finer average fiber diameter and an increased porosity. Also, the oil absorption characteristics and oil/water separation abilities of these fibrous membranes were experimentally studied. In contrast to the 84.55% oil/water separation efficiency of melt‐electrospun PLA fibrous membranes, PLA/CNF exhibits the highest oil/water separation efficiency at 93.54%, whereas PLA/NaCl achieves a maximum efficiency of 90.29%. These findings show the applicability of the eco‐friendly PLA‐based melt electrospun fibrous membrane in the treatment of oily wastewater.

AbstractPerovskite solar cells are actively investigated for their potential as highly efficient and cost‐effective photovoltaic devices. However, a significant challenge in their practical application is enhancing their durability. Particularly, these cells are expected to be subjected to heating by sunlight in real‐world operating environments. Therefore, high‐temperature durability and device operation under such conditions are critical. Our study aims to improve the durability of perovskite solar cells for practical applications by examining their temperature coefficients at elevated temperatures using MA‐free compositions. We assessed these coefficients and investigated their correlation with the ideality factor, revealing that carrier recombination markedly affects the temperature behavior of these cells. Our methodology involves simple J‐V measurements to evaluate device degradation at high temperatures, paving the way for further research to enhance device performance in such environments.

Published: July 2024

AbstractTherapeutic oligonucleotides (ONs) have great potential to treat many diseases due to their ability to regulate gene expression. However, the inefficiency of standard purification techniques to separate the target sequence from molecularly similar variants is hindering development of large scale ON manufacturing at a reasonable cost. Multicolumn Countercurrent Solvent Gradient Purification (MCSGP) is a valuable process able to bypass the purity‐yield tradeoff typical of single‐column operations, and hence to make the ON production more sustainable from both an economic and environmental point of view. However, operating close to the optimum of MCSGP can be challenging, resulting in unstable process performance and in a drift in product quality, especially when running a continuous process for extended periods where process parameters such as temperature are prone to variation. In this work, we demonstrate how greater process robustness is introduced in the design and execution of MCSGP for the purification of a 20mer single‐stranded DNA sequence through the implementation of UV‐based dynamic control. With this novel approach, the cyclic steady state was reached already in the third cycle and disturbances coming from fluctuations in the feed quality, loading amount and temperature were effectively compensated allowing a stable operation close to the optimum. In response to the perturbations, the controlled process kept the standard deviation on product recovery below 3.4%, while for the non‐controlled process it increased up to 27.5%.

Abstract22(R)‐hydroxycholesterol (22(R)‐HCHO) is a crucial precursor of steroids biosynthesis with various biological functions. However, the production of 22(R)‐HCHO is expensive and unsustainable due to chemical synthesis and extraction from plants or animals. This study aimed to construct a microbial cell factory to efficiently produce 22(R)‐HCHO through systems metabolic engineering. First, we tested 7‐dehydrocholesterol reductase (Dhcr7s) and cholesterol C22‐hydroxylases from different sources in Saccharomyces cerevisiae, and the titer of 22(R)‐HCHO reached 128.30 mg L−1 in the engineered strain expressing Dhcr7 from Columba livia (ClDhcr7) and cholesterol 22‐hydroxylase from Veratrum californicum (VcCyp90b27). Subsequently, the 22(R)‐HCHO titer was significantly increased to 427.78 mg L−1 by optimizing the critical genes involved in 22(R)‐HCHO biosynthesis. Furthermore, hybrid diploids were constructed to balance cell growth and 22(R)‐HCHO production and to improve stress tolerance. Finally, the engineered strain produced 2.03 g L−1 of 22(R)‐HCHO in a 5‐L fermenter, representing the highest 22(R)‐HCHO titer reported to date in engineered microbial cell factories. The results of this study provide a foundation for further applications of 22(R)‐HCHO in various industrially valuable steroids.

The findings show that GEO has a positive impact on firm performance through green innovation and green entrepreneurship image. Furthermore, green value co‐creation moderates the relationship between GEO and green innovation, suggesting the importance of external stakeholders in facilitating the firm GEO. This study emphasizes the multidimensional nature of the link between GEO and firm performance, emphasizing the significance of taking both mediating and moderating factors into account. It adds to the growing body of knowledge on sustainability, entrepreneurship, and corporate success by offering a comprehensive framework that captures the subtle interplay of these elements. The findings have implications for firms looking to capitalize on the benefits of GEO and green innovation while also acknowledging the need of collaborative value co‐creation in gaining long‐term competitive advantage.
Evaluation of two transposases for improving expression of recombinant proteins in Chinese hamster ovary cell stable pools by co‐transfection and supertransfection approaches

Published: July 2024

AbstractTransposons are genetic elements capable of cutting and pasting genes of interest via the action of a transposase and offer many advantages over random or targeted integration of DNA in the creation of Chinese hamster ovary (CHO) cell lines for recombinant protein expression. Unique transposases have different recognition sites, allowing multiple transposases to be co‐transfected together. They also allow for supertransfection (transfection on a previously transfected pool or cell line) with a second transposase to integrate additional copies of the same gene or an additional gene without disruption of the previously integrated DNA which to our knowledge has not been previously described in literature. Two fluorescent proteins, EGFP and tagRFP657, were either co‐transfected or supertransfected into CHO cells using two unique transposases and showed high expression efficiency with similar expression levels (measured as mean fluorescence intensity), regardless of whether the genes were co‐transfected or supertransfected onto an existing stable pool. Additionally, dual selection of the genes, both in the absence of L‐glutamine and the presence of puromycin, led to higher expression levels than single selection alone. These results demonstrate that supertransfection using unique transposases could be a useful strategy for increasing titers of existing cell lines or for overexpressing helper (non‐therapeutic) genes to improve expression and/or product quality of existing pools and cell lines, potentially saving significant time and resources.
