Evaluation of Activated Sludge for Biodegradation of Propylene Glycol as an Aircraft Deicing Fluid
Authors: Delorit Justin D. , Racz LeeAnn 
Published: October 2013

ABSTRACTAircraft deicing fluid used at airport facilities is often collected for treatment or disposal in order to prevent serious ecological threats to nearby surface waters. This study investigated lab scale degradation of propylene glycol, the active ingredient in a common aircraft deicing fluid, by way of a laboratory‐scale sequencing batch reactor containing municipal waste water treatment facility activated sludge performing simultaneous organic carbon oxidation and nitrification. The ability of activated sludge to remove propylene glycol was evaluated by studying the biodegradation and sorption characteristics of propylene glycol in an activated sludge medium. The results indicate sorption may play a role in the fate of propylene glycol in AS, and the heterotrophic bacteria readily degrade this compound. Therefore, a field deployable bioreactor may be appropriate for use in flight line applications.

Published: October 2013

AbstractIn the simulation of skiing the force between ski and snow is a decisive factor. We decompose the reaction force into a penetration force normal to the snow surface, a shear force and friction. Two portable measurement devices were developed to study the penetration and shear forces for compacted snow on groomed ski slopes. The penetration force was assessed by measuring the penetration depth of a ski-tool loaded normal to the snow surface. For the shear force the tangential load was measured when the snow began to fail. Overall 236 penetration and 108 shear experiments were conducted on different types of snow. The penetration force was proportional to the volume of snow displaced by the ski-tool. The failure shear force was proportional to the penetration depth multiplied by the length of the tool. The constants of proportionality, HV and Sf, are material parameters of snow. The snow hardness, HV, varied between 0.04 and 90 N mm–3 and the failure shear stress, Sf, between 0.04 and 0.40 N mm–2. In another investigation, skiing turns were simulated using the presented snow reaction forces. Maximum deviations between computed and real trajectories were <1 % of the overall length of the runs.

Published: October 2013

• Premise of the study: Bathysa australis is a common subcanopy tree from the Atlantic Forest that is pollinated by bees and wasps and produces autochoric seeds. This species exhibits great phenotypic plasticity along the elevational gradient of Serra do Mar in southeastern Brazil. We expect to assess the genetic diversity and gene flow between populations of this species along the elevational gradient.• Methods and Results: We developed a microsatellite‐enriched genomic library for B. australis, and 10 microsatellite loci were successfully amplified, ranging from one to 13 alleles per locus. The observed and expected heterozygosities ranged from 0.333 to 0.900 (average: 0.629) and 0.564 to 0.900 (average: 0.742), respectively.• Conclusions: These are the first microsatellite markers developed for the genus Bathysa and may be useful in other species of the Condamineeae tribe. These primers will be an important tool for studies of population ecology and conservation genetics.
Near Field Communication - Which Potentials Does NFC Bring for Teaching and Learning Materials?
Authors: Ebner Martin , Maierhuber Martin 
Published: October 2013

Near Field Communication (NFC) is deemed to be a future technology with a lot of potential in many areas. One of those areas, learning and teaching, will be covered in this article, showing possible usages of NFC with teaching and learning materials. With a lot of new NFC capable devices presented recently, this technology can be utilized in many areas, including the arbitrarily growing field of mobile learning.
Mobile devices, especially smartphones, can help to close the gap between printed media and online media. Several methods, e.g. two-dimensional barcodes, have already been used to connect the digital world with printed media but almost all of them caused inconveniences or difficulties. NFC presents an easy to use way to share and communicate directly between capable devices or tags that can be applied almost anywhere.
In this publication a first insight to the potential of NFC for teaching and learning content is given. A prototype is programmed to allow data transformation between the print media and the smartphone. It can be summarized that NFC will be the logical successor of QR-Codes.
Las instituciones religiosas en la transformación normativa contemporánea en la sexualidad en Chile
Authors: Palma Irma 
Published: October 2013

Este texto analiza la relación entre orientaciones normativas de las instituciones religiosas y las prácticas sexuales de los sujetos, más precisamente los efectos de la adscripción y la observancia en contexto de transformación tanto de las religiones como de sexualidad en la sociedad chilena contemporánea. Se analiza la Encuesta Nacional de Comportamiento Sexual, realizada en 1998 por la Comisión Nacional del SIDA, CONASIDA, con la colaboración de la Agence Nationale de Recherches sur le SIDA, ANRS, de Francia, con sujetos nacidos entre 1929 y 1978 (N= 5407). El análisis muestra los efectos de género producidos por la observancia, más intensos sobre las mujeres y diferenciados por lógicas de individualización entre católicas, y de subjetivación comunitaria, entre evangélicas; también muestra las transformaciones generacionales de la secularización y la reducción progresiva de los efectos de las instituciones religiosas sobre las prácticas de los sujetos.

AbstractObjectiveThis study aimed to evaluate subjective cognitive, physical, and mental health symptoms as well as objective cognitive deficits in COVID‐19 patients 1 year after infection.MethodsThis was a cross‐sectional study. Seventy‐four patients, who contracted a SARS‐CoV‐2 infection in 2020, underwent an in‐person neuropsychological assessment in 2021. This included standardized tests of memory, attention, and executive functions. In addition, participants also responded to scales on subjective attention deficits, mental health symptoms, and fatigue. Patients' scores were compared to published norms.ResultsPatients (N = 74) had a median age of 56 years (42% female). According to the initial disease severity, they were classified as mild (outpatients, 32%), moderate (hospitalized, non‐ICU‐admitted, 45%), or severe (ICU‐admitted, 23%). Hospitalized patients were more often affected than outpatients. In general, deficits were most common in attention (23%), followed by memory (15%) and executive functions (3%). Patients reported increased levels of fatigue (51%), anxiety (30%), distractibility in everyday situations (20%), and depression (15%). An additional analysis suggested an association between lower scores in an attention task and hyperferritinemia. As indicated by a hierarchical regression analysis, subjective distractibility was significantly predicted by current anxiety and fatigue symptoms but not by objective attention performance (final model, adj‐R
2 = 0.588, P < 0.001).InterpretationOne year after infection, COVID‐19 patients can have frequent attention deficits and can complain about symptoms such as fatigue, anxiety, and distractibility. Anxiety and fatigue, more than objective cognitive deficits, have an impact on the patients' experienced impairments in everyday life.

AbstractStructural topology and symmetry of a two‐dimensional (2D) network play pivotal roles in defining its electrical properties and functionalities. Here, a binary buckled honeycomb lattice with C3v symmetry, which naturally hosts topological Dirac fermions and out‐of‐plane polarity, is proposed. It is successfully achieved in a group IV‐V compound, namely monolayer SiP epitaxially grown on Ag(111) surface. Combining first‐principles calculations with angle‐resolved photoemission spectroscopy, the degeneration of the Dirac nodal lines to points due to the broken horizonal mirror symmetry is elucidated. More interesting, the SiP monolayer manifests metallic nature, which is mutually exclusive with polarity in conventional materials. It is further found that the out‐of‐plane polarity is strongly suppressed by the metallic substrate. This study not only represents a breakthrough of realizing intrinsic polarity in 2D metallic material via ingenious design but also provides a comprehensive understanding of the intricate interplay of many exotic low‐dimensional quantum phenomena.

Abstract2D perovskite passivation strategies effectively reduce defect‐assisted carrier nonradiative recombination losses on the perovskite surface. Nonetheless, severe energy losses are causing by carrier thermalization, interfacial nonradiative recombination, and conduction band offset still persist at heterojunction perovskite/PCBM interfaces, which limits further performance enhancement of inverted heterojunction PSCs. Here, 5,10,15,20‐tetrakis(pentafluorophenyl)porphyrin (5FTPP) is introduced between 3D/2D perovskite heterojunction and PCBM. Compared to tetraphenylporphyrin without electron‐withdrawing fluoro‐substituents, 5FTPP can self‐assemble with PCBM at interface into donor–acceptor (D–A) complex with stronger supramolecular interaction and lower energy transfer losses. This rapid energy transfer from donor (5FTPP) to acceptor (PCBM) within femtosecond scale is demonstrated to enlarge hot carrier extraction rates and ranges, reducing thermalization losses. Furthermore, the incorporation of polystyrene derivative (PD) reinforces D–A interaction by inhibiting self‐π–π stacking of 5FTPP, while fine‐tuning conduction band offset and suppressing interfacial nonradiative recombination via Schottky barrier, dipole, and n‐doping. Notably, the multidentate anchoring of PD‐5FTPP with FA+, Pb2+, and I− mitigates the adverse effects of FA+ volatilization during thermal stress. Ultimately, devices with PD‐5FTPP achieve a power conversion efficiency of 25.78% (certified: 25.36%), maintaining over 90% of initial efficiency after 1000 h of continuous illumination at the maximum power point (65 °C) under ISOS‐L‐2 protocol.

AbstractIn this work, silyl ethers of phenols and alcohols have been successfully prepared and tested as neutral carbon (silicon) centered radical precursors. The organophotocatalyzed oxidation (by the Fukuzumi catalyst) of these ethers caused the cleavage of a C−Si (or a Si−Si) bond for the release of the desired radical to be used for the forging of C(sp3) −C(sp3) (or C(sp3) −Si) bonds via a Giese reaction.

Published: July 2024

AbstractFullerenes, as single crystals, present exceptional mechanical and physical properties due to their hollow spherical molecular structure consisting of carbon atoms connected by covalent bonds. The idea of linking these allotropes of carbon to create monolayer networks has now been accomplished experimentally. The question that remains to be answered is if these synthesized single‐layered nanosheets of fullerene present comparable properties with graphene monolayers. To answer this important question and to estimate the full tensile stress–strain behavior of quasi‐tetragonal as well as quasi‐hexagonal configurations of C60 planar networks, several Molecular Dynamics simulations are performed in this work by using a new REAXFF and the AIREBO‐M potential. Various mechanical properties, such as Young's modulus, Poisson's ratio, ultimate tensile strength, ultimate tensile strain, and fracture energy at failure of C60 monolayers of several sizes, are computed and compared with the results reported in the literature. Furthermore, a comprehensive discussion is made regarding the significant influence of the adopted potential on the numerical predictions of the elastic mechanical and fracture behavior of the fullerene nanosheets.

AbstractThe success of immunotherapy for cancer treatment is limited by the presence of an immunosuppressive tumor microenvironment (TME); Therefore, identifying novel targets to that can reverse this immunosuppressive TME and enhance immunotherapy efficacy is essential. In this study, enrichment analysis based on publicly available single‐cell and bulk RNA sequencing data from gastric cancer patients are conducted, and found that tumor‐intrinsic interferon (IFN) plays a central role in TME regulation. The results shows that KDM3A over‐expression suppresses the tumor‐intrinsic IFN response and inhibits KDM3A, either genomically or pharmacologically, which effectively promotes IFN responses by activating endogenous retroviruses (ERVs). KDM3A ablation reconfigures the dsRNA‐MAVS‐IFN axis by modulating H3K4me2, enhancing the infiltration and function of CD8 T cells, and simultaneously reducing the presence of regulatory T cells, resulting in a reshaped TME in vivo. In addition, combining anti‐PD1 therapy with KDM3A inhibition effectively inhibited tumor growth. In conclusions, this study highlights KDM3A as a potential target for TME remodeling and the enhancement of antitumor immunity in gastric cancer through the regulation of the ERV‐MAVS‐IFN axis.

AbstractIntegration of solar cell and secondary battery cannot only promote solar energy application but also improve the electrochemical performance of battery. Lithium–sulfur battery (LSB) is an ideal candidate for photoassisted batteries owing to its high theoretical capacity. Unfortunately, the researches related the combination of solar energy and LSB are relatively lacking. Herein, a freestanding photoelectrode is developed for photoassisted lithium–sulfur battery (PALSB) by constructing a heterogeneous structured Au@N‐TiO2 on carbon cloths (Au@N‐TiO2/CC), which combines multiple advantages. The Au@N‐TiO2/CC photoelectrode can produce the photoelectrons to facilitate sulfur reduction during discharge process, while generating holes to accelerate sulfur evolution during charge process, improving the kinetics of electrochemical reactions. Meanwhile, Au@N–TiO2/CC can work as an electrocatalyst to promote the conversion of intermediate polysulfides during charge/discharge process, mitigating induced side reactions. Benefiting from the synergistic effect of electrocatalysis and photocatalysis, PALSB assembled with an Au@N‐TiO2/CC photoelectrode obtains ultrahigh specific capacity, excellent rate performance, and outstanding cycling performance. What is more, the Au@N‐TiO2/CC assembled PALSB can be directly charged under light illumination. This work not only expands the application of solar energy but also provides a new insight to develop advanced LSBs.

AbstractHydrogels present attractive opportunities as flexible sensors due to their soft nature and tunable physicochemical properties. Despite significant advances, practical application of hydrogel‐based sensor is limited by the lack of general routes to fabricate materials with combination of mechanical, conductive, and biological properties. Here, a multi‐functional hydrogel sensor is reported by in situ polymerizing of acrylamide (AM) with N,N′‐bis(acryloyl)cystamine (BA) dynamic crosslinked silver‐modified polydopamine (PDA) nanoparticles, namely PAM/BA‐Ag@PDA. Compared with traditional polyacrylamide (PAM) hydrogel, the BA‐Ag@PDA nanoparticles provide both high‐functionality crosslinks and multiple interactions within PAM networks, thereby endowing the optimized PAM/BA‐Ag@PDA hydrogel with significantly enhanced tensile/compressive strength (349.80 kPa at 383.57% tensile strain, 263.08 kPa at 90% compressive strain), lower hysteresis (5.2%), improved conductivity (2.51 S m−1) and excellent near‐infrared (NIR) light‐triggered self‐healing ability. As a strain sensor, the PAM/BA‐Ag@PDA hydrogel shows a good sensitivity (gauge factor of 1.86), rapid response time (138 ms), and high stability. Owing to abundant reactive groups in PDA, the PAM/BA‐Ag@PDA hydrogel exhibits inherent tissue adhesiveness and antioxidant, along with a synergistic antibacterial effect by PDA and Ag. Toward practical applications, the PAM/BA‐Ag@PDA hydrogel can conformally adhere to skin and monitor subtle activities and large‐scale movements with excellent reliability, demonstrating its promising applications as wearable sensors for healthcare.
Myokine secretion during moderate‐intensity physical activity: Dose–response of interleukin 6 to walking duration
Authors: Kistner Timothy M. , Tavormina Anna , Lieberman Daniel E. 
Published: July 2024

AbstractDuring vigorous physical activity, contracting muscles secrete a variety of immunomodulatory and metabolic factors called myokines that perform a variety of functions. Foremost among these is interleukin 6 (IL‐6), which increases fatty acid mobilization and stimulates anti‐inflammatory cytokine release. Despite being well characterized in vigorous exercise contexts, whether IL‐6 is secreted during moderate‐intensity activities such as walking is unclear. This is especially pertinent as regular walking is one of the oldest and most common forms of physical activity and comes with a variety of health benefits, which may be coordinated in part by IL‐6 signaling. To test the hypothesis that IL‐6 release occurs during evolutionarily normal physical activity contexts like long distance walking, we performed a dose–response experiment to test the effect of walking duration on IL‐6 secretion. Thirteen participants completed four moderate‐intensity walking trials (55% HRmax) of varying durations (30 min, 1 h, 2 h, and 3 h) in a randomized order with intervening washout periods of at least 1 week. Using a linear mixed effects model, we found that IL‐6 levels modestly increased during only the 2 h and 3 h walking trials. These results suggest that small frequent increases in IL‐6 signaling may be an important mechanism underlying the health benefits of regular walking. Furthermore, this finding raises the possibility that IL‐6 secretion is an adaptation to fuel physical activity, especially during periods of negative energy balance.

Published: July 2024

AbstractAdvanced multiple resonance thermally activated delayed fluorescence (MR‐TADF) emitters with high efficiency and color purity have emerged as a research focus in the development of ultra‐high‐definition displays. Herein, we disclose an approach to modulate the charge‐transfer excited states of MR emitters via intramolecular covalent bond locking. This strategy can promote the evolution of strong intramolecular charge‐transfer (ICT) states into weak ICT states, ultimately narrowing the full‐width at half‐maximum (FWHM) of emitters. To modulate the ICT intensity, two octagonal rings are introduced to yield molecule m‐DCzDAz‐BNCz. Compounds m‐CzDAz‐BNCz and m‐DCzDAz‐BNCz exhibit bright light‐green and green fluorescence in toluene, with emission maxima of 504 and 513 nm, and FWHMs of 28 and 34 nm, respectively. Sensitized organic light‐emitting diodes (OLEDs) employing emitters m‐CzDAz‐BNCz and m‐DCzDAz‐BNCz exhibit green emission with peaks of 508 and 520 nm, Commission Internationale de L'Eclairage (CIE) coordinates of (0.12, 0.65) and (0.19, 0.69), and maximum external quantum efficiencies (EQEs) of 30.2 % and 32.6 %, respectively.
