Authors: Mandsberg Nikolaj K. , Serna Julian A. , Levkin Pavel A. 
Published: July 2024

AbstractRemote manipulation of microcargo is essential for miniaturized automated experiments in fields such as biology, chemistry, and diagnostics, allowing efficient use of scarce, expensive, or hazardous materials. Current methods for manipulating microcargo are generally limited to droplets as cargo and rely on reduced substrate‐cargo friction and special substrate‐cargo interactions (electrowetting, anisotropic wetting, water‐repellency, etc.) to enable cargo mobility. This limits the versatility of substrate and cargo choice. Here, CART (Carrier‐based Actuatable and Reprogrammable Transport) is presented as a solution to these challenges. By introducing a carrier between the substrate and the cargo, CART physically separates them, eliminating the need to reduce substrate‐cargo friction and the need for substrate‐cargo matching. CART devices are easy to realize, tailor, and post‐functionalize. A photo‐polymerizable phase‐separating resin is used to 3D‐print porous carriers that are then infused with ferrofluid to make them magnetically responsive, enabling untethered cargo manipulation on both solid and liquid substrates. Using CART, various cargos can be remotely moved, rotated/mixed, inverted, and lifted, further facilitating interaction between two carriers for transferring, merging, and tunably splitting cargo. Overall, CART advances microcargo manipulation by decoupling cargo from the substrate and leveraging magnetic responsiveness for untethered, versatile control across different environments, opening up new actuation‐modalities.

AbstractIonic thermoelectric (i‐TE) gels have attracted widespread attention in flexible electronics due to their flexibility, leakage‐free, low toxicity, and converting low‐grade waste heat into electricity. For practical application, it is strongly desirable to fabricate negative‐thermopower (n‐type) i‐TE gels with excellent mechanical performances, which is still a big challenge. Herein, a multi‐hierarchical network structure is proposed to simultaneously improve the TE and mechanical performance. Such structure including hierarchical hydrogen bonds, coordination bonds, and dense polymer chains is realized via the synergy of the coordination effect of polymer to cations and the Hofmeister effect of anions to polymer. As a result, the optimized gel exhibits not only negative thermopower up to −3.69 mV K−1 with a conductivity of 0.15 S m−1 at room temperature, but also outstanding tensile strength (>6.7 MPa), elongation at break (>1100%), and toughness (>43 MJ m−3), which is the toughest n‐type i‐TE gel reported to date. In addition, these n‐type i‐TE gels present good freeze tolerance (−58.53 °C) and dry resistance. Furthermore, the application potentials of the i‐TE device are proven in converting human thermal power into electricity. These findings provide a new way to obtain high‐performance n‐type i‐TE materials by synergistic anion and cation action on polymers.

Published: July 2024

AbstractDynamic covalent organic frameworks (COFs) offer a promising platform for bioinspired soft actuators, yet transitioning their typical microcrystalline or single crystalline morphology to a flexible film suitable for wearable technology applications still remains a grand challenge. Herein, aiming at this issue, this work synthesizes an innovative class of hygrosensitive COF films, denoted as JNU‐hygroCOF, with superior mechanical strength, chemical stability and tunable thickness from nanometer to micrometer scales through solution‐processable sol‐gel method. These JNU‐hygroCOF films display exceptional moisture‐driven actuation capabilities through modulating the intramolecular hydrogen bonds, which act as specific locks that open and close the molecular rotor of N─N bond responding to guest molecules, within the unique azine‐pyridine molecular skeleton. By integrating these new JNU‐hygroCOF films into a portable respiratory monitoring system, a proactive and preventive solution for diagnosing and managing respiratory disorders such as sleep apnea and asthma has been provided.

AbstractFewer layer graphene principally has a higher surface area to support more catalytic sites for energy conversion, but it is still challenging to synthesize monolayer graphene without oxidation from graphite at a low cost. Here, a method for synergistically thinning graphene layers and constructing catalytic sites to create a superior bifunctional oxygen catalyst through vapor intercalation of multi‐layer graphene or its derivatives is described. The synthesized small sheet sizes of 1–2 layer graphene‐supported FeN4 and FeCo active sites exhibit superior reversible activity of oxygen reduction and evolution reactions with a low overall overpotential of 0.648 V. The sheet‐shaped catalyst is further used to fabricate flexible soft‐packed and wearable cable‐type quasi‐solid‐state zinc–air batteries, achieving high performances (>188 mW cm−2, >450 cycles) and enabling smartphone charging. DFT calculations reveal that fewer layer graphene coupled with atomic FeN4 and alloy FeCo sites enables lower Gibbs free energy for favorable OOH* intermediate adsorption/desorption benefiting superior oxygen redox process. This study introduces a strategy for scalable synthesis of 1–2 layer graphene from cheap microcrystalline graphite minerals for wearable and durable energy devices.

Published: July 2024

AbstractDry eye affects majority of the global population, causing significant discomfort or even visual impairment, of which inflammation plays a crucial role in the deterioration process. This highlights the need for effective and safe anti‐inflammatory treatments to achieve satisfactory therapeutic outcomes. This study focuses on the potential of tetrahedral framework nucleic acids (tFNA), a self‐assembled nucleic acid material, as a simple and rapid treatment for oxidative stress and inflammation‐induced disorders associated with dry eye. Mechanistically, tFNA is found to effectively alleviate dry eye damage by promoting corneal epithelial healing, restoring goblet cell function, and facilitating tear secretion recovery. Through RNA‐seq analysis, it is observed that tFNA treatment normalizes the expression levels of most genes. Further exploration of the mechanism reveals that tFNA reduces excessive production of reactive oxygen species and modulates the inflammatory microenvironment, especially through cGAS‐STING pathway thereby levels of inflammatory cytokines, including MMP9 and IL‐6, are reduced. Additionally, tFNA demonstrates excellent safety performance without causing damage to the eye. Importantly, this study represents a successful application of nanophase materials with nucleic acid biological features for the effective treatment of dry eye, highlighting the potential clinical use of tFNA in the treatment of dry eye.

AbstractTuberculosis, a fatal infectious disease caused by Mycobacterium tuberculosis (M.tb), is difficult to treat with antibiotics due to drug resistance and short drug half‐life. Phototherapy represents a promising alternative to antibiotics in combating M.tb. Exploring an intelligent material allowing effective tuberculosis treatment is definitely appealing, yet a significantly challenging task. Herein, an all‐in‐one biomimetic therapeutic nanoparticle featured by aggregation‐induced second near‐infrared emission, granuloma‐targeting, and self‐oxygenation is constructed, which can serve for prominent fluorescence imaging‐navigated combined phototherapy toward tuberculosis. After camouflaging the biomimetic erythrocyte membrane, the nanoparticles show significantly prolonged blood circulation and increased selective accumulation in tuberculosis granuloma. Upon laser irradiation, the loading photosensitizer of aggregation‐induced emission photosensitizer elevates the production of reactive oxygen species (ROS), causing M.tb damage and death. The delivery of oxygen to relieve the hypoxic granuloma microenvironment supports ROS generation during photodynamic therapy. Meanwhile, the photothermal agent, Prussian blue nanoparticles, plays the role of good photothermal killing effect on M.tb. Moreover, the growth and proliferation of granuloma and M.tb colonies are effectively inhibited in the nanoparticle‐treated tuberculous granuloma model mice, suggesting the combined therapeutic effects of enhancing photodynamic therapy and photothermal therapy.

AbstractMoiré superlattices, composed of two layers of transition metal dichalcogenides with a relative twist angle, provide a novel platform for exploring the correlated electronic phases and excitonic physics. Here, a gas‐flow perturbation chemical vapor deposition (CVD) approach is demonstrated to directly grow MoS2 bilayer with versatile twist angles. It is found that the formation of twisted bilayer MoS2 homostructures sensitively depends on the gas‐flow perturbation modes, correspondingly featuring the nucleation sites of the second layer at the same (homo‐site) as or at the different (hetero‐site) from that of the first layer. The commensurate twist angle of ≈22° in homo‐site nucleation strategy accounts for ≈16% among the broad range of twist angles due to its low formation energy, which is in consistence with the theoretical calculation. More importantly, moiré interlayer excitons with the enhanced photoluminescence (PL) intensity and the prolonged lifetime are evidenced in the twisted bilayer MoS2 with a commensurate angle of 22°, which is owing to the reason that the strong moiré potential facilitates the interlayer excitons to be trapped in the moiré superlattices. The work provides a feasible route to controllably built twisted MoS2 homostructures with strong moiré potential to investigate the correlated physics in twistronics systems.

Published: July 2024

AbstractAlkynes are simple yet important organic feedstocks. The selenylation of alkynes is able to produce complex selenium‐containing compounds in a facile way. Although there are some reviews about the selenylation of alkynes, most of them focus on one specific reaction or what types of products that can be obtained. There is a lack of attention given to the various uses of different selenium reagents and their mechanisms. This review mainly focuses on recent advances (2013–2023) based on diverse selenium reagents. Mechanisms and how the added reagents work will be discussed. Different reaction types, including difunctionalization, Se‐annulation, spiro‐cyclization, C−Se coupling, click reaction will be recorded in this review. The regioselectivity can be achieved through various mechanisms, including radicals, seleniraniums or electrophilic cyclization. We hope it will do help for future research in this area.
Reconfigurability‐Encoded Hierarchical Rectifiers for Versatile 3D Liquid Manipulation
Authors: Miao Jiaqi , Tsang Alan C. H. 
Published: July 2024

AbstractManipulating small‐volume liquids is crucial in natural processes and industrial applications. However, most liquid manipulation technologies involve complex energy inputs or non‐adjustable wetting gradient surfaces. Here, a simple and adjustable 3D liquid manipulation paradigm is reported to control liquid behaviors by coupling liquid–air–solid interfacial energy with programmable magnetic fields. This paradigm centers around a hierarchical rectifier with magnetized microratchets, using Laplace pressure asymmetry to enable multimodal directional steering of various surface tension liquids (23–72 mN m−1). The scale‐dependent effect in microratchet design shows its superiority in handling small‐volume liquids across three orders of magnitude (100–103 µL). Under programmed magnetic fields, the rectifier can reconfigure its morphology to harness interfacial energy to exhibit richer liquid behaviors without dynamic real‐time control. Reconfigured rectifiers show improved rectification performance in the inertia‐dominant fluid regime, i.e., a remarkable 2000‐fold increase in the critical Weber number for pure ethanol. Moreover, the rectifier's switchable reconfigurations offer flexible control over liquid transport directions and spatiotemporally controllable 3D liquid manipulation reminiscent of inchworm motions. This scalable liquid manipulation paradigm promotes versatile engineering and biochemistry applications, e.g., portable liquid purity testing (screening resolution <1 mN m−1), logical open‐channel microfluidics, and automated chemical reaction platforms.

Published: July 2024

AbstractThere is a growing interest in exploring nanometer‐thin 2D oxide semiconductor transistors for future scaled and multifunctional (e.g., ultraflexible and high transparency) devices. However, further development is hindered due to the degraded device performance with nanometer‐thin 2D oxide semiconductor channels and the use of costly vacuum‐based techniques. Here, 2D (2.7 nm thick) c‐axis‐aligned crystalline In─S─O channel material processed from aqueous solution is reported. The 2D In─S─O transistors based on Si/SiO2 substrates exhibit high mobility (µ) of 22.15 cm2 V−1 s−1, on/off current ratio (Ion/Ioff) of ≈107, and good bias stress stability. Detailed investigations show that this achievement is attributed to the highly c‐axis‐aligned crystalline structure, well‐designed In─S─O channel material, and atomically smooth surface. Furthermore, the 2D In─S─O channel is integrated with an aqueous sol‐gel‐derived 6 nm thick high‐k ZrO2 insulator. The all‐aqueous‐solution‐based quasi‐2D In─S─O/ZrO2 devices show high µ of 15.65 cm2 V─1 s─1, Ion/Ioff of ≈106, and low operating voltage of 1.5 V. This 2D c‐axis‐aligned crystalline wide‐bandgap oxide semiconductor channel material opens tremendous opportunities for multifunctional, ultra‐scaled and low‐cost electronics.

Published: July 2024

AbstractIn the era of minimally invasive surgery, esophagectomy remains a highly invasive procedure with a high rate of postoperative complications. Preoperative risk assessment is essential for planning esophagectomy in patients with esophageal cancer, and it is crucial to implement evidence‐based perioperative management to mitigate these risks. Perioperative support from multidisciplinary teams has recently been reported to improve the perioperative nutritional status and long‐term survival of patients undergoing esophagectomy. Intraoperative management of anesthesia and fluid therapy also significantly affects short‐term outcomes after esophagectomy. In this narrative review, we outline the recent updates in the perioperative management of esophagectomy, focusing on preoperative risk assessment, intraoperative management, and perioperative support by multidisciplinary teams to improve operative outcomes.

Published: July 2024

AbstractThe isoindigo and its derivatives have rapidly garnered attention as widely employed electron‐deficient moieties, finding extensive applications in organic field‐effect transistors. In this study, four different isoindigo‐based organic semiconductor polymers were synthesized via a Stille coupling reaction of four isoindigo molecules with varying side chains serving as acceptors and bithiophene as donors. Furthermore, their optical, electrochemical, thermal stability, and other relevant properties were comprehensively evaluated. These polymers exhibited remarkable electrochemical and thermal stability attributed to their low LUMO energy level, which facilitates effective electrical contact between the semiconductor layer and the source/drain while ensuring excellent air stability for the semiconductor polymers. Additionally, solution‐gate field‐effect transistors prepared using these polymers achieved hole mobilities of 10−2 cm2 V−1 S−1 along with an Ion/Ioff ratio of 8.39×103, demonstrating exceptional field‐effect performance.
Ligand‐Directed Synthesis of a Self‐Organized Chloro‐Bridged Cubic Pd(II) Cage Showing Selective Encapsulation of Phenols
Authors: Sarkar Meghamala , Kushwaha Vikash , Boomishankar Ramamoorthy 
Published: July 2024

AbstractThe synthesis and guest recognition properties of a neutral Pd24‐cubic cage, [{Pd3(NiPr)3PO}8(μ2‐Cl)24] 1 are reported. The formation of the cubical assembly takes place by an exclusive one‐pot ligand‐assisted pathway directed by an oximido linker. The initial coordination of the oximido ligand pre‐organizes the [Pd3(NiPr)3PO]3+ polyhedral building units into a tetrameric intermediate, which then transforms into an oximido‐tethered tetrahedral assembly and to the cubical cage 1 in the presence of chloride ions. In the absence of the directing oximido linker, no cage formation was observed, and the Pd6‐precursor was found to undergo self‐condensation, giving rise to a new pentameric polyhedral cluster, [Pd5{(NiPr)3PO}2(OAc)2(OH)2] 2. The central cavity of the cube has been probed for guest encapsulation studies, which shows a high binding with phenolic guest molecules with association constants of the order of 104–105 M−1. The favorable formation of host–guest complexes was attributed to the strong hydrogen bonding interactions between the host and guest functional groups.

AbstractIn recent years, the electronic structures of organocuprates in general and the complex [Cu(CF3)4]− in particular have attracted significant interest. A possible key indicator in this context is the reactivity of these species. Nonetheless, this aspect has received only limited attention. Here, we systematically study the series of tetra‐alkyl cuprates [MenCu(CF3)4−n]− and their unimolecular reactivity in the gas phase, which includes concerted formal reductive eliminations as well as radical losses. Through computational studies, we characterize the electronic structures of the complexes and show how these are connected to their reactivity. We find that all [MenCu(CF3)4−n]− ions feature inverted ligand fields and that the distinct reactivity patterns of the individual complexes arise from the interplay of different effects.

ABSTRACTAustralian South Sea Islanders are a distinctive cultural group comprising descendants of over 60000 labourers who came to Australia from Vanuatu, Solomon Islands and elsewhere in the Western Pacific between 1863 and 1904. “Blackbirded” labourers were commonly referred to as victims of a slave trade, though many also came voluntarily to work in the sugar plantations of northern New South Wales and Queensland. The advent of racist exclusionary immigration policies introduced from 1901 further forced South Sea Islanders to the margins of colonial society. Yet many Australian South Sea Islanders would argue their untold history speaks to resilience and overcoming adversity. Australian South Sea Islanders have a distinctive cultural heritage, including material culture, oral traditions embedded in the landscape and connections to places – from sugar mills to domestic sites – revealed archaeologically. This heritage must be approached sensitively given its association with sometimes difficult histories but is crucial to understanding the contributions of Australian South Sea Islanders to Australian society, contemporary communities and identities, and historical and social significance across multiple scales. Collaborative research with Australian South Sea Islanders pushes the boundaries of “community archaeology” by taking a slow approach to research, reframing ethnographic objects and cultural landscapes, and producing an archaeology that can include many voices.

Published: July 2024

AbstractSolving mathematical story problems has proven to be a challenge for primary school students with and without developmental disabilities. The present study replicates a behavior analytic study (Neef et al.) by teaching three autistic Chinese students in inclusive education classes to solve addition/subtraction story problems by acquiring an overt precurrent behavior chain. The intervention was effective for all participants by employing a multiple baseline design across behaviors. Additionally, the study extends Neef et al. by conducting maintenance, generalization, and social validity assessments, and expands the teaching format to distance learning (telehealth). The results and limitations are discussed based on Skinner's conceptualization of problem‐solving and its clinical application in teaching complex mathematical skills to students with developmental disabilities.
