AbstractIron selenides have emerged as appealing anodes for Na+‐storage due to their natural abundance, good redox reversibility, and high theoretical capacity. Nevertheless, exploring a carbon‐free iron selenide anode with long‐term stability and high‐rate capability remains an intractable challenge. Herein, a 3D carbon‐free iron selenide electrode is designed by heterointerface with SeP bond engineering strategy to realize outstanding Na+‐storage performance. Theoretical calculations on the stress deformation confirm the construction of Fe7Se8/Fe3(PO4)2 not only enables excellent resistance‐to‐deformation ability but also exhibits strong mechanically stable against sodiation–desodiation. Such fascinating properties combined with the accelerated Na+ diffusion kinetics and enhanced electronic conductivity endowed by the 3D interconnected framework contribute to impressive cycling stability and superb rate performance for Na+‐storage. Consequently, the designed 3D Fe7Se8/Fe3(PO4)2 composite with a high tap density of 0.91 cm3 g−1 displays a stable specific capacity of 277.1 mAh cm−3 at 30 A g−1, and outstanding long‐term cycle stability of up to 1500 cycles at 5 A g−1 without obvious capacity decay. The proposed engineering strategy and results provide new insight to design carbon‐free advanced electrodes for future practical applications.

AbstractDue to the deficient catalase, abundant reduced iron and low acidic environment in lysosomes, inducing lysosomal membrane permeabilization (LMP) through Fenton reaction‐based reactive oxygen species (ROS) generation recently attracts increasing attention in cancer therapy. However, the lysosomal membranes are protected by highly glycosylated membrane proteins and several endolysosomal damage‐response mechanisms can rapidly repair the injured lysosomes. To produce sufficient ROS and cause complete lysosomal membranes rupture, a lysosome‐targeted ROS inducer, N‐(3‐Aminopropyl) morpholine grafted cross‐linked lipoic acid vesicles with vitamin C‐loading (VC@N3AMcLAVs), is developed. VC@N3AMcLAVs efficiently accumulate in lysosomes and convert into two redox couples LA/DHLA (dihydrolipoic acid, reduced form of LA) and VC/DHA (dehydroascorbic acid, oxidized form of VC) by the lysosomal glutathione, which can not only produce a large amount of H2O2 by pro‐oxidant action but also accelerate iron transformation through the cyclic redox reactions between each other and cause the efficient conversion of the generated H2O2 into highly toxic •OH. Both in vitro and in vivo experiments demonstrate that VC@N3AMcLAVs can effectively enhance ROS production and boost LMP, finally initiation irreversible death of tumor cells via ferroptosis pathway, thus representing a potential anticancer drug for cancer therapy.

AbstractAuxetic materials are the materials that can display negative Poisson's ratio that describes the degree to which a material contracts (or expands) transversally when axially strained. Human stem cells sense the mechanical properties of the microenvironment, including material surface properties, stiffness, and Poisson's ratio. In this study, six different auxetic polyurethane (PU) foams with different elastic modulus (0.7–1.8 kPa) and Poisson's ratio (−0.1 to −0.5) are used to investigate lineage specification of human induced pluripotent stem cells (hiPSCs). The surfaces of the foams are modified with chitosan or heparin to enhance the adhesion and proliferation of hiPSCs. Then, the vascular and neural differentiation of hiPSCs are investigated on different foams with distinct elastic modulus and Poisson's ratio. With different auxetic foams, cells show differential adherent density and differentiation capacity. Chitosan and heparin surface functionalization promote the hindbrain and hippocampal markers, but not forebrain markers during neural patterning of hiPSCs. Properly surface engineered auxetic scaffolds can also promote vascular differentiation of hiPSCs. This study represents a versatile and multifunctional scaffold fabrication approach and can lead to a suitable system for establishing hiPSC culture models in applications of neurovascular disease modeling and drug screening.

Published: November 2022

AbstractAqueous zinc‐ion batteries are highly desirable for sustainable energy storage, but the undesired Zn dendrites growth severely shortens the cycle life. Herein, a triple‐gradient electrode that simultaneously integrates gradient conductivity, zincophilicity, and porosity is facilely constructed for a dendrite‐free Zn anode. The simple mechanical rolling‐induced triple‐gradient design effectively optimizes the electric field distribution, Zn2+ ion flux, and Zn deposition paths in the Zn anode, thus synergistically achieving a bottom‐up deposition behavior for Zn metals and preventing the short circuit from top dendrite growth. As a result, the electrode with triple gradients delivers a low overpotential of 35 mV and operates steadily over 400 h at 5 mA cm‐2/2.5 mAh cm‐2 and 250 h at 10 mA cm‐2/1 mAh cm‐2, far surpassing the non‐gradient, single‐gradient and dual‐gradient counterparts. The well‐tunable materials and structures with the facile fabrication method of the triple‐gradient strategy will bring inspiration for high‐performance energy storage devices.

AbstractThe regulation of atomic and electronic structures of active sites plays an important role in the rational design of oxygen evolution reaction (OER) catalysts toward electrocatalytic hydrogen generation. However, the precise identification of the active sites for surface reconstruction behavior during OER remains elusive for water‐alkali electrolysis. Herein, irreversible reconstruction behavior accompanied by copper dynamic evolution for cobalt iron layered double hydroxide (CoFe LDH) precatalyst to form CoFeCuOOH active species with high‐valent Co species is reported, identifying the origin of reconstructed active sites through operando UV‐Visible (UV–vis), in situ Raman, and X‐ray absorption fine‐structure (XAFS) spectroscopies. Density functional theory analysis rationalizes this typical electronic structure evolution causing the transfer of intramolecular electrons to form ligand holes, promoting the reconstruction of active sites. Specifically, unambiguous identification of active sites for CoFeCuOOH is explored by in situ 18O isotope‐labeling differential electrochemical mass spectrometry (DEMS) and supported by theoretical calculation, confirming mechanism switch to oxygen‐vacancy‐site mechanism (OVSM) pathway on lattice oxygen. This work enables to elucidate the vital role of dynamic active‐site generation and the representative contribution of OVSM pathway for efficient OER performance.

AbstractThe development of rare‐earth‐doped luminescent materials with single component, multicolor, and multimode still remains a challenge. Here, rare‐earth‐based double perovskite single crystals (Cs2NaYbCl6 DPSCs) are fabricated with low phonon energy of 134 cm−1, which offers great potential to serve as highly efficient luminescent host materials. Subsequently, Er3+, Tm3+, and Ho3+ are successfully incorporated into Cs2NaYbCl6 host to form Cs2NaLnxYb1−xCl6 (Ln = Er, Tm, and Ho) DPSCs, realizing efficient dual‐mode polychromatic emission. Under 980 nm laser excitation, Cs2NaLnxYb1−xCl6 DPSCs show high upconversion (UC) efficiencies of 12.9%, 7.2%, and 3.1% for Cs2NaEr0.3Yb0.7Cl6, Cs2NaTm0.02Yb0.98Cl6, and Cs2NaHo0.3Yb0.7Cl6, respectively. Meanwhile, Cs2NaErxYb1−xCl6 DPSCs exhibit the adjustable size (0.5–10 mm) and tunable UC or down‐shifting emission colors from yellow, green to red upon 980, 1540, or 380 nm excitation. Moreover, the DPSCs demonstrate weak concentration and thermal quenching effect, and excellent resistance against oxygen, heat and humidity. Finally, the anti‐counterfeiting and information encryption applications based on multicolor emitting DPSCs are designed and realized.

AbstractPassive daytime radiative cooling (PDRC) is a game‐changing strategy for cooling, aiming to alleviate the major problems such as global warming. It is featured with zero energy consumption and zero environmental pollution, bringing about revolutionary change compared with conventional cooling systems. The key challenge in the exciting arena of PDRC research lies in the material design and engineering, aiming to meet the requirement for the optical characteristics on the two very different ranges of wavelength. To possess the optimal cooling performance, materials constructed for daytime radiative cooling are required to show extremely low absorptivity for wavelengths of solar irradiation (0.3–2.5 µm) to minimize the thermal load, while having high emissivity within the atmospheric transmission window (8–13 µm) for emitting heat out directly to the outer space. The current review takes a specific perspective of material science and engineering to summarize the most recent advances in PDRC. The fundamental principles for daytime radiative cooling and material design are summarized, and recent works on PDRC material engineering and correlated applications are highlighted. Technical details and prospects for each type of PDRC materials are discussed. The future challenges and opportunities of PDRC materials are also proposed.

AbstractBackgroundNight shift work is associated with adverse pathophysiologic effects on maternal and fetal well‐being. Although emergency medicine (EM) residents work frequent night shifts, there is no existing guidance for residency program directors (PDs) regarding scheduling pregnant residents. Our study assessed scheduling practices for pregnant EM residents, differences based on program and PD characteristics, barriers and attitudes toward implementing a formal scheduling policy, and PDs' awareness of literature describing adverse effects of night shifts on maternal–fetal outcomes.MethodsWe conducted an anonymous, web‐based survey of U.S. EM residencies (N = 276). Quantitative data were summarized; chi‐square analysis and logistic regression were used to assess relationships between program and PD characteristics and schedule accommodations. Qualitative description was used to analyze an open‐ended question, organizing findings into major and minor themes.ResultsOf the 167 completed surveys (response rate 61%), 67% of programs reported no formal policy for scheduling pregnant residents but made adjustments on an individual basis including block changes (85%), decreased (46%) or no night shifts (34%), and working shifts earlier in pregnancy to cover later shifts (20%). Barriers to adjustments included staffing constraints (60%), equity concerns (45%), or impact on wellness (41%) among all residents and privacy (28%). PDs endorsed scheduling adjustments as important (mean 8.1, 0–10 scale) and reported guidance from graduate medical education governance would be useful (60%). Larger program size, but not PD gender or proportion of female residents, was associated with an increased likelihood of scheduling modifications. Twenty‐five percent of PDs reported little knowledge of literature regarding night shift work and pregnancy. Qualitative themes supported quantitative findings.ConclusionsMost EM residency programs do not have formal scheduling policies for pregnant residents, but most PDs support making adjustments and do so informally. More education and guidance for PDs are needed to promote the development of formal policies.

AbstractManufacturers of nontraditional crop additives may claim products will enhance yield and improve economic return, yet many offer only grower testimonials for product validation rather than unbiased, peer‐reviewed research. If the products do not perform as described, they may serve to reduce grower revenue. To investigate these claims in potato (Solanum tuberosum L.), field trials were conducted near Othello, Washington from 2016 to 2019 on 27 nontraditional additive treatments composed of 32 products. Treatments were applied using one or more application techniques: in‐furrow and surface bands, foliar sprays, and chemigations/fertigations (applied through irrigation system) per manufacturer recommendations and in addition to grower standard practices. Conventional nutrients were applied to be nonlimiting to potato growth. Economic return was calculated using a mock processing contract and adjusted for individual product costs that ranged from US$15 to US$889 ha−1. Treatment‐adjusted gross return values ranged from <7.7% to >8.5% the grower standard treatment value, and total yields ranged from 108 to 136 Mg ha−1, but differences from the control were not significant for any treatment. Reclaim, a surfactant, and OneUP and NutriCal, both specialty fertilizers, increased US No. 1 yield, average tuber weight, and tuber specific gravity, respectively. Some of the tested products may provide other benefits like soil health improvement or water use reduction but those parameters were not included in this study. Growers should avoid applying unproven products until they are tested and approved by an unbiased, trustworthy research entity.

Intimate partner violence is a major problem in Australia, impacting many families that are on the cusp of disruption and intervention by the child protection system. Using an innovative method of inquiry, the article explores the role of dedicated men's workers in a South Australian non‐government organisation's intensive family service that works towards keeping families safe and together. The dedicated men's worker positions are integrated into a multidisciplinary model that works with fathers who have been a part of situational violence within the family. The men's workers' (and co‐authors') reflections offer insight into systemic barriers, practical therapeutic interventions, engagement work with fathers, how this is approached, and the various outcomes experienced. Blending auto‐ethnography reflections, elements of rapid ethnographic assessment, and the use of rigorous and accelerated data reduction, we demonstrate the need for increased supports for some fathers. These should include therapeutic engagement and working with the underlying trauma of fathers to ensure the whole family is supported and offered opportunity for healing and sustainable preservation. We also consider the more encompassing lifeworlds of the men and the need to drive and support broader sociocultural shifts.
A novel concept for pure hydrogen production and a massive reduction in CO2 emissions from the formaldehyde absorption process

Published: November 2022

AbstractThe Formox process is a well‐known process for formalin generation, which uses iron‐molybdenum oxide as a catalyst. Typically, the off‐gas from the formaldehyde absorption column in Formox process is burnt in the emission control system (ECS), resulting to produce a huge amount of CO2. This work proposes a modified process to remove formaldehyde and volatile organic compounds from the stack of formaldehyde absorbing tower. Steam reforming reactions in a novel fixed‐bed tubular membrane reactor is used instead of combustion reactions in a conventional fixed‐bed reactor in ECS. The process was modeled to evaluate the role of membrane reactor for CO2 mitigation in Formox process. The collected data from a domestic formalin plant were used for modeling purposes. The model was validated against experimental measurements obtained from other works. A good consistency was observed. The improvement in CO2 emission mitigation, as well as H2 production, was achieved by applying the Pd‐Ag membrane reactor filled with copper‐based catalyst. The CO2 emission rate considerably changed from 6,700 to 575 kg/day. Furthermore, by using the proposed reactor, the emission of formaldehyde and methanol vapors throughout the ECS plant were eliminated. The essential parameters such as reactor pressure, temperature, and membrane thickness on reactor performance were evaluated. By increasing the feed temperature, the carbon dioxide production rate decreases, and pure hydrogen production rate increases. The higher CO2 generation was observed at elevated pressures. The effect of membrane thickness on CO2 emission was negligible.

AbstractThe emission behaviors of volatile organic compounds (VOCs) can be characterized by the key parameters: the initial concentration (m0), partition coefficient (K) and the diffusion coefficient (D). The MHE‐GC method was validated to determine the emission characteristics of VOCs (Benzene, Toluene, Ethylbenzene, P‐xylene, M‐xylene, Styrene, and O‐xylene) in regenerated PET fibers. This work has studied the effects of fiber size, sample weight incubation time and incubation temperature on the detection of these VOCs. It showed finer fiber sample with less sample facilitated the emission of VOCs in fibers above detectable limit. The optimized headspace incubation time, fiber sample weight, and headspace incubation temperature were selected as 60 min, about 0.8 g and 110 °C, respectively. In addition, incubation temperature has a negative effect on the gas/fiber partition coefficient. The fibers with greater fineness showed higher activation energy, which revealed a positive release of VOCs from fibers. The relative standard deviation (RSD/%) of detection was 3%–10%. The present method is reliable and suitable for use in testing of the VOCs content in fiber‐related materials.

AbstractSilicone rubber/ethylene‐vinyl acetate copolymer/magnesium sulfate whisker composites containing ethylene‐acrylic acid copolymer (MS/SR/EVM/EAA) as a compatibilizer were successfully prepared. Moreover, the magnesium sulfate whisker surface was modified with 3 wt% of silane coupling agent (KH570), resulting in composites including (unmodified magnesium sulfate whisker) uMS/SR/EVM, (modified magnesium sulfate whisker) mMS/SR/EVM, and mMS/SR/EVM/EAA were compared. The values of thermal decomposition activation energy (Ea) calculated by the two different methods (Kissinger and Friedman methods) show that the composites filled with 5 and 20 phr whiskers have lower values of activation energy (Ea) than the SR/EVM blend. The tensile strength of composites with a 5 phr modified whisker is 14.5 MPa, which is higher than that of the SR/EVM blend and uMS5/SR/EVM composite. The tear strength of the composite with 20 phr mMS is 51.6 kN m−1, much higher than that of the composite with 20 phr uMS and SR/EVM blend. The mechanical properties were also investigated after thermal aging of the composites at 85°C for 48 h. The thermal conductivity of the composites with high filler loading was studied.

AbstractMixed matrix membranes (MMMs), which combine the characteristics of inorganic nanofillers and organic matrices, have received wide attention because of their good permeability and selective performance for separating CO2 from industrial waste gases. In this work, the amino‐GO‐loaded bentonite (amino GO‐Bent) was prepared by loading NH2 on the GO surface with a large number of functional sites. Firstly, by introducing NH2 on the surface of GO and then interacting with bentonite (Bent) organically modified by silane coupling agents through amide bonding. Mixed matrix membranes (MMMs) with an area of 623.7 cm2 and homogeneous texture were prepared using amino‐GO‐Bent as inorganic filler to improve the membrane selectivity for CO2/N2 and CO2/CH4 separation. The results show that the introduction of amino GO‐Bent in MMMs can greatly improve the CO2 permeability and obtain high CO2 permeation performance: 2.67945 × 10−7 cm3 (STP)·cm/s/cm2/cmHg, and the selectivity of CO2/N2 and CO2/CH4 can reach 307.28 and 325.97, respectively. The two selective values were 14 and 18 times higher than those of pure PVDF membranes, and the performance of MMMs far exceeded the Robeson upper limit in 2008, respectively.
