AbstractOrganic light‐emitting transistors (OLETs), a kind of highly integrated and minimized optoelectronic device, demonstrate great potential applications in various fields. The construction of high‐performance OLETs requires the integration of high charge carrier mobility, strong emission, and high triplet exciton utilization efficiency in the active layer. However, it remains a significant long‐term challenge, especially for single component active layer OLETs. Herein, the successful harvesting of triplet excitons in a high mobility emissive molecule, 2,6‐diphenylanthracene (DPA), through the triplet‐triplet annihilation process is demonstrated. By incorporating a highly emissive guest into the DPA host system, an obvious increase in photoluminescence efficiency along with exciton utilization efficiency results in an obvious enhancement of external quantum efficiency of 7.2 times for OLETs compared to the non‐doped devices. Moreover, well‐tunable multi‐color electroluminescence, especially white emission with Commission Internationale del'Eclairage of (0.31, 0.35), from OLETs is also achieved by modulating the doping concentration with a controlled energy transfer process. This work opens a new avenue for integrating strong emission and efficient exciton utilization in high‐mobility organic semiconductors for high‐performance OLETs and advancing their related functional device applications.

AbstractPoor ion and high electron transport at the grain boundaries (GBs) of ceramic electrolytes are the primary reasons for lithium filament infiltration and short‐circuiting of all‐solid‐state lithium metal batteries (ASLMBs). Herein, it is discovered that Li2CO3 at the GBs of Li7La3Zr2O12 (LLZO) sheets is reduced to highly electron‐conductive LiCx during cycling, resulting in lithium penetration of LLZO. The ionic and electronic conductivity of the GBs within LLZO can be simultaneously tuned using sintered Li3AlF6. The generated LiAlO2 (LAO) infusion and F‐doping at the GBs of LLZO (LAO‐LLZOF) significantly reduce the Li2CO3 content and broaden the energy bandgap of LLZO, which decreases the electronic conductivity of LAO‐LLZOF. LAO forms a 3D continuous ion transport network at the GB that significantly improves the total ionic conductivity. Lithium penetration within LLZO is suppressed and an all‐solid‐state LiFePO4/LAO‐LLZOF/Li battery stably cycled for 5500 cycles at 3 C. This work reveals the chemistry of Li2CO3 at the LLZO GBs during cycling, presents a novel lithium penetration mechanism within garnet electrolytes, and provides an innovative method to simultaneously regulate the ion and electron transport at the GBs in garnet electrodes for advanced ASLMBs.

Published: January 2023

AbstractThe human immune system is an interaction network of biological processes, and its dysfunction is closely associated with a wide array of diseases, such as cancer, infectious diseases, tissue damage, and autoimmune diseases. Manipulation of the immune response network in a desired and controlled fashion has been regarded as a promising strategy for maximizing immunotherapeutic efficacy and minimizing side effects. Integration of “smart” bioresponsive materials with immunoactive agents including small molecules, biomacromolecules, and cells can achieve on‐demand release of agents at targeted sites to reduce overdose‐related toxicity and alleviate off‐target effects. This review highlights the design principles of bioresponsive immunotherapeutic materials and discusses the critical roles of controlled release of immunoactive agents from bioresponsive materials in recruiting, housing, and manipulating immune cells for evoking desired immune responses. Challenges and future directions from the perspective of clinical translation are also discussed.

Published: January 2023

AbstractThe energy efficiency of metal–air batteries and water‐splitting techniques is severely constrained by multiple electronic transfers in the heterogenous oxygen evolution reaction (OER), and the high overpotential induced by the sluggish kinetics has become an uppermost scientific challenge. Numerous attempts are devoted to enabling high activity, selectivity, and stability via tailoring the surface physicochemical properties of nanocatalysts. Lattice‐strain engineering as a cutting‐edge method for tuning the electronic and geometric configuration of metal sites plays a pivotal role in regulating the interaction of catalytic surfaces with adsorbate molecules. By defining the d‐band center as a descriptor of the structure–activity relationship, the individual contribution of strain effects within state‐of‐the‐art electrocatalysts can be systematically elucidated in the OER optimization mechanism. In this review, the fundamentals of the OER and the advancements of strain‐catalysts are showcased and the innovative trigger strategies are enumerated, with particular emphasis on the feedback mechanism between the precise regulation of lattice‐strain and optimal activity. Subsequently, the modulation of electrocatalysts with various attributes is categorized and the impediments encountered in the practicalization of strained effect are discussed, ending with an outlook on future research directions for this burgeoning field.
Record‐High Work‐Function p‐Type CuBiP2Se6 Atomic Layers for High‐Photoresponse van der Waals Vertical Heterostructure Phototransistor

Published: January 2023

AbstractThe notable lack of intrinsic p‐type 2D layered semiconductors has hindered the engineering of 2D devices for complementary metal oxide semiconductors (CMOSs). Herein, a novel quaternary intrinsic p‐type 2D semiconductor, CuBiP2Se6 atomic layers, is introduced into the 2D family. The semiconductor displays a high work function of 5.26 eV, a moderate hole mobility of 1.72 cm2 V−1 s−1, and an ultrahigh on/off current exceeding 106 at room temperature. To date, 5.26 eV is the highest work‐function recorded in p‐type 2D materials, indicating the ultrastable p‐type behavior of CuBiP2Se6. Additionally, a multilayer graphene/CuBiP2Se6/multilayer graphene (MLG/CBPS/MLG)‐based fully vertical van der Waals heterostructure phototransistor is designed and fabricated. This device exhibits outstanding optoelectronic performance with a responsivity (R) of 4.9 × 104 A W−1, an external quantum efficiency (EQE) of 1.5 × 107%, a detectivity (D) of 1.14 × 1013 Jones, and a broad working wavelength (400–1100 nm), respectively. This is comparable to state‐of‐the‐art 2D devices. Such excellent performance is attributed to the ultrashort transmit length and nondestructive/defect‐free contacts. This leads to faster response speed and eliminates Fermi‐level pinning effects. Moreover, ultrahigh responsivity and detectivity endow the device with applaudable imaging sensing capability. These results make CuBiP2Se6 an ideal p‐type candidate material for next‐generation CMOSs logic devices.

Published: January 2023

AbstractDental implants are the most common therapeutic approach for resolving tooth loss and damage. Despite technical advances in treatment, implant failure rates can be as high as 23% with the major cause of peri‐implantitis: a multi‐species bacterial infection. With an annual growth rate in implant placements of 8.78% per annum, implant failure caused by bacterial infection is a significant oral and general health issue. The rise in antibiotic resistance in oral bacteria further adds pressure to implant failure; thus, there is a need for adjunctive therapy to improve implant outcomes. Due to the broad spectrum of activity and a low risk of inducing bacterial resistance, peptide antibiotics are emerging as a promising implant coating material to reduce/prevent peri‐implantitis and improve dental implant success rates. In this review, we summarised the current strategies of coating antimicrobial peptides (AMPs) onto dental implant material surfaces with multi‐functional properties to enhance osteoblast growth and prevent bacterial infections. This review compared the recent reported literature on dental implant coating with AMPs, which will provide an overview of the current dental implant coating strategies using AMPs and insights for future clinical applications.

Published: January 2023

AbstractThe baroreflex is a multi‐input, multi‐output physiological control system that regulates blood pressure by modulating nerve activity between the brainstem and the heart. Existing computational models of the baroreflex do not explicitly incorporate the intrinsic cardiac nervous system (ICN), which mediates central control of heart function. We developed a computational model of closed‐loop cardiovascular control by integrating a network representation of the ICN within central control reflex circuits. We examined central and local contributions to the control of heart rate, ventricular functions, and respiratory sinus arrhythmia (RSA). Our simulations match the experimentally observed relationship between RSA and lung tidal volume. Our simulations predicted the relative contributions of the sensory and the motor neuron pathways to the experimentally observed changes in the heart rate. Our closed‐loop cardiovascular control model is primed for evaluating bioelectronic interventions to treat heart failure and renormalize cardiovascular physiology.
A mathematical modeling approach for supply chain management under disruption and operational uncertainty
Authors: Badejo Oluwadare , Ierapetritou Marianthi 
Published: January 2023

AbstractIn this work, we proposed a two‐stage stochastic programming model for a four‐echelon supply chain problem considering possible disruptions at the nodes (supplier and facilities) as well as the connecting transportation modes and operational uncertainties in form of uncertain demands. The first stage decisions are supplier choice, capacity levels for manufacturing sites and warehouses, inventory levels, transportation modes selection, and shipment decisions for the certain periods, and the second stage anticipates the cost of meeting future demands subject to the first stage decision. Comparing the solution obtained for the two‐stage stochastic model with a multi‐period deterministic model shows that the stochastic model makes a better first stage decision to hedge against the future demand. This study demonstrates the managerial viability of the proposed model in decision making for supply chain network in which both disruption and operational uncertainties are accounted for.

AbstractBackgroundComparisons of late‐onset Alzheimer's disease (LOAD) and autosomal dominant AD (ADAD) are confounded by age.MethodsWe compared biomarkers from cerebrospinal fluid (CSF), magnetic resonance imaging, and amyloid imaging with Pittsburgh Compound‐B (PiB) across four groups of 387 cognitively normal participants, 42 to 65 years of age, in the Dominantly Inherited Alzheimer Network (DIAN) and the Adult Children Study (ACS) of LOAD: DIAN mutation carriers (MCs) and non‐carriers (NON‐MCs), and ACS participants with a positive (FH+) and negative (FH–) family history of LOAD.ResultsAt baseline, MCs had the lowest age‐adjusted level of CSF Aβ42 and the highest levels of total and phosphorylated tau‐181, and PiB uptake. Longitudinally, MC had similar increase in PiB uptake to FH+, but drastically faster decline in hippocampal volume than others, and was the only group showing cognitive decline.DiscussionPreclinical ADAD and LOAD share many biomarker signatures, but cross‐sectional and longitudinal differences may exist.

Published: January 2023

AbstractAtmospheric water harvesting represents a promising technique to address water stress. Advanced adsorbents have been rationally designed to achieve high water uptake, yet their water sorption kinetics and regeneration temperature greatly limit water production efficiency. Herein, we demonstrated that 2D covalent organic frameworks (COFs), featuring hydrophobic skeleton, proper hydrophilic site density, and 1D open channels significantly lowered the water diffusion and desorption energy barrier. DHTA‐Pa COF showed a high water uptake of 0.48 g/g at 30 % R.H. with a remarkable adsorption rate of 0.72 L/Kg/h (298 K) and a desorption rate of 2.58 L/Kg/h (333 K). Moreover, more than 90 % adsorbed water could be released within 20 min at 313 K. This kinetic performance surpassed the reported porous materials and boosted the efficiency for multiple water extraction cycles. It may shed light on the material design strategy to achieve high daily water production with low‐energy input.
Increasing the firmness of wax‐based oleogels using ternary mixtures of sunflower wax with beeswax:candelilla wax combinations

Published: January 2023

AbstractOleogels were prepared with 5% wax in soybean oil using mixtures of beeswax (BW) and candelilla wax (CLW) with ratios of 10:90, 30:70, 50:50, and 60:40 BW:CLW, and the same series where 10% of the total wax was substituted with sunflower wax (SFW). The hypothesis that SFW would increase the firmness of the oleogels without affecting the melting properties was tested. Firmness of one‐wax oleogels decreased from SFW > CLW > BW. Oleogels with 50:50 BW:CLW and 60:40 BLW:CLW had equal firmness to pure 5% SFW oleogels. SFW significantly increased oleogel firmness and reduced the softening that occurred between 4°C and 22°C. Increased firmness was also found with rice bran wax and behenyl‐behenate (C44) addition, but not with wax esters with chain lengths ranging from 30 to 40 carbons (C30 to C40). By differential scanning calorimetry, SFW significantly decreased the melting point of oleogels with 10:90 and 30:70 BW:CLW mixtures but significantly increased the melting point of those with 50:50 and 60:40 BW:CLW mixtures. However, the solid fat content melting curves were not significantly influenced by SFW addition. These results indicate that mixed wax oleogels had greater hardness and elasticity, and that the long chain wax esters contributed by SFW helped to improve the strength of oleogels without negatively affecting their melting properties.

Published: January 2023

AbstractHighly thermally and electrically conductive polypropylene (PP) nanocomposites were prepared by incorporating high‐aspect‐ratio copper nanowires (CuNW). Surface treatment of the CuNW was important for dispersion and compatibility. A CuNW network was first embedded in a PP matrix, followed by removal of the protective layer on CuNW. At a volume fraction of 2.5%, the thermal conductivity was enhanced by 234% compared to the neat PP. The electrical conductivity significantly increased to 500 S/cm, which is 16 orders of magnitude greater than the neat PP. This PP nanocomposite is attractive for housings for electronic devices and antistatic packaging.
In situ nanofibrillar composite fiber: A model system for understanding the structural evolution of crosslinked nanofibrils

Published: January 2023

AbstractIn situ formed nanofibrils, which are formed from the deformation of dispersed phase polymer during the shearing/stretching process, offer exciting opportunities for large scale manufacture of materials with high strength and toughness. However, how the topological structure, especially crosslinking network structure of dispersed phase polymer, affects the structural evolution of nano/microfibrils is remaining unclear. Here, the nanofibrillar morphology of nanofibrillar composite fibers is manipulated via controlling the crosslinking network structure of dispersed phase. By changing the length of crosslinker and mol ratio of crosslinkers, the diameter of nanofibrils can be controlled. The rheological property of the crosslinked microspheres and corresponding morphology of in situ formed nanofibrils confirm that the inhomogeneous crosslinking network shows lower storage modulus and consistency coefficient, leading to higher deformation adaptability of crosslinking network and smaller diameter of the nanofibrils. The distribution of nanofibrils along the axial direction of composite fiber greatly improved the tensile strength and toughness of composite fiber to 74 MPa and 719 MJ/m3, which are 45% and 180% increasement compared with the counterpart pure PMMA fiber. The findings in current study provide a new strategy to control the nanofibrillar morphology by increasing the heterogeneity of crosslinking network structure of the dispersed phase polymer.

Published: January 2023

AbstractPoly(arylene ether)s with different molecular weights were synthesized via a two‐step nucleophilic substitution polymerization by adjusting reaction parameters based on phenolphthalein (PHT) and decafluorobiphenyl (DFBP). The chemical structures and properties were identified by Fourier transform infrared, NMR, gel permeation chromatography, differential scanning calorimetry, thermogravimetric analysis, dynamic thermomechanical analysis (DMA), and so forth. The number‐average molecular weight (Mn) of the resulting polymers was in the range of 23.0–49.3KDa. FPAEs (polyarylether including perfluorobiphenyl structure) were demonstrated to have outstanding thermo‐resistance with 5% weight loss temperature of about 482–520°C (N2) and high‐glass transition temperature (about 240–250°C). FPAEs can be dissolved in conventional organic solvents, possessing excellent film‐forming properties. The good mechanical properties of FPAEs were confirmed by the DMA data, with Young's modulus greater than 1.0 Gpa and modulus retention rate at 230°C >67%. FPAEs also showed good hydrophobicity and low‐water absorption, in particular, FPAE‐1 (FPAE‐1‐5 were the polycondensation products of PHT and DFBP, just the polymerization conditions were slightly modified) exhibited favorable dielectric properties: at 1 MHz, the dielectric constant and dielectric loss was 2.58 and 0.0053, respectively. Thus, FPAE‐1 has broad prospective applications in microelectronic devices and communication technology.
A methodology for the self‐training and self‐assessing of new GPR practitioners: Measuring diagnostic proficiency illustrated by a case study of a historic African‐American cemetery for unmarked graves
Authors: Martin Jacob Michael , Everett Mark E. 
Published: January 2023

AbstractIn ground penetrating radar (GPR) surveys of African‐American cemeteries suspected to contain unmarked graves, determining the proficiency of a new GPR practitioner is vital and perhaps even more fundamental than that of the GPR hardware, deployment configuration and software. Proficiency may be defined as the practitioner's true‐positive, true‐negative, false‐positive (i.e., false alarms) and false‐negative (i.e., misses) percentages. We embarked on this research as a means to improve our own proficiency in unmarked grave detection and to develop an algorithm by which to improve the proficiency of any new GPR practitioner. After surveying the Salem Cemetery in Brazos County, TX, and the Old Danville‐Shepherd Hill Cemetery in Montgomery County, TX, we first classified subsurface targets based on in‐field, visual inspection of the real‐time, onscreen, unprocessed (except for an automatic gain control) GPR B‐scans. We then developed a proxy for ground‐truthing that allowed us to calculate the proficiency of the in‐field classifications. From this proxy, we established a quantitative prevalence threshold for identifying or rejecting a subsurface object as a target of interest. Its quantitative nature allowed us to quantitatively control and adjust that threshold, a threshold we set at 70% likely to be to a specific target of interest. We show that our classification accuracy increased from 66.2% at the Salem Cemetery to 75.0% at the Old Danville‐Shepherd Hill Cemetery and, through use of diagnostic evaluations originally developed for medical imaging and herein applied to geophysics, showed that the accuracy improved due to increases in true‐negative classifications, that is, in examining real‐time, onscreen, mostly unprocessed GPR B‐scans, discerning a potential target and correctly concluding it was not an unmarked grave. This research outlines the procedure we developed to measure the proficiency of a new GPR practitioner.

Published: January 2023

AbstractSynthesis of maleic anhydride (MA) and styrene (St) copolymers possessing ultra‐high molecular weight, strictly alternating regularity and high glass transition temperature simultaneously is still an issure with great challenge. Herein, the spontaneous alternating copolymerization of MA and St derivatives were investigated by using various Lewis acids. In the presence of alkyl aluminum or butyl magnesium, the MA−St alternating copolymers with ultra‐high molecular weight (Mn≤166.5×104) and high glass transition temperature (211 °C≤Tg≤216 °C) were produced and the microstructure of MA−St copolymers were analyzed by 1H and 13C NMR spectra. The copolymerizations of MA with St derivatives, including divinylbenzene, p‐butenyl styrene, p‐methoxystyrene, trans‐anethole, p‐fluorostyrene and p‐chlorostyrene, also were explored by using AlOctyl3 as an activator in toluene at 50 °C.
