Differential Microwave Resonator Sensor for Real-Time Monitoring of Volatile Organic Compounds

In this work, a noninvasive microwave gas sensor suitable for accurate and real-time tracking of volatile organic compounds concentration is presented. The proposed differential sensor was comprised of two independent split-ring resonators in power splitter/combiner configuration to enhance the robustness of the sensor to changes in environmental parameters. The designwas fabricatedon a Rogers RT/duroid 5880 high-frequency substrate and operated at f(s) = 5.12 GHz and f(r) = 5.65 GHz, referring to the sensing and reference resonant frequencies, respectively. A thin layer of polydimethylsiloxane was used as an interface layer in the sensing resonator region with the strongest electric field to enable gas sensing with high sensitivity. The performance of the sensor was validated by introducing different volatile organic compounds, such as acetone, methanol, ethanol, and isopropyl alcohol. Time-based responses of the sensor demonstrated the capability of the sensor to monitor different concentrations of acetone vapor ranging from low, 387 to 1935 ppm, with the sensitivity of 0.02 mdB/ppm and high concentrations, 3878 to 62048 ppm, with sensitivity of 0.0125 mdB/ppm.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6338-55-2, in my other articles.

Live predator stress in adolescence results in distinct adult behavioral consequences and dorsal diencephalic brain activation patterns

Exposure to traumatic events during childhood increases the risk of adult psychopathology, including anxiety, depression, alcohol use disorders and their co-morbidity. Early life trauma also results in increased symptom complexity, treatment resistance and poor treatment outcomes. The purpose of this study was to establish a novel rodent model of adolescent stress, based on an ethologically relevant life-threatening event, live predator exposure. Rats were exposed to a live predator for 10 min. at three different time points (postnatal day (PND)31, 46 and 61). Adult depression-, anxiety-like behaviors and ethanol consumption were characterized well past the last acute stress event (two weeks). Behavioral profiles across assessments were developed to characterize individual response to adolescent stress. CNS activation patterns in separate groups of subjects were characterized after the early (PND31) and last predator exposure (PND61). Subjects exposed to live-predator adolescent stress generally exhibited less exploratory behavior, less propensity to venture into open spaces, a decreased preference for sweet solutions and decreased ethanol consumption in a two-bottle preference test. Additional studies demonstrated blunted cortisol response and CNS activation patterns suggestive of habenula, rostromedial tegmental (RMTg), dorsal raphe and central amygdala involvement in mediating the adult consequences of adolescent stress. Thus, adolescent stress in the form of live-predator exposure results in significant adult behavioral and neurobiological disturbances. Childhood trauma, its impact on neurodevelopment and the subsequent development of mood disorders is a pervasive theme in mental illness. Improving animal models and our neurobiological understanding of the symptom domains impacted by trauma could significantly improve treatment strategies.

Gelatin/Poly (vinyl alcohol)/Inorganic filler composites for phantom breasts

The effect of the various inorganic filler (Zn, ZnO, CuO, Co(NO3)(2), Fe2O3) on the structural, electronic, atomic, and absorption properties to the performance of composite phantom breast with polyvinyl alcohol (PVA) as a binder has been studied. The bonding characteristic analyzed from the Fourier transforms infrared (FTIR) spectra and the structural properties in the form of the crystallite size, porosity, and dislocation density determined from the X-ray diffraction (XRD) spectra. The atomic, electronic, and absorption ability of composite were analyzed from the irradiation intensity after the X-rays for the energies from 60 keV to 85 keV at 10 mAs passing through the samples. The functional group of C=O, C-H, and C-O show covalent bonding as a cross-linking between atoms from the various filler and the atom from the matrix materials. The crystallite size shows a direct correlation between the linear attenuation coefficient and the mass attenuation coefficient. The linear attenuation coefficient of composite gelatin/PVA/ZnO is 0.255 cm(-1), for composite gelatin/PVA/CuO is 0.233 cm(-1) shows good for breast phantom, and for composite gelatin/PVA/Zn is 0.343 cm(-1 )shows excellent characteristics for breast phantom. This study provided a new composite with excellent characteristics as a guide to produce breast phantom.

Effect of multiscale reinforcement by fiber surface treatment with polyvinyl alcohol/graphene oxide/oxidized carbon nanotubes on the mechanical properties of reinforced hybrid fiber composites

Polyvinyl alcohol-graphene oxide-oxidized carbon nanotube (PVA-GO-OCNT) hybrid coatings were adopted to modify glass fibers (GFs) and carbon fibers (CFs), and modified GF/CF-reinforced polyurethane hybrid composites (PVA-GO-OCNTs-HFs/PUs) with different concentric hybrid structures were prepared. The synergistic effect of the hybrid structure and surface modification of hybrid fibers (HFs) on the mechanical properties of hybrid composites was investigated systematically. The results show that the hybrid structure can optimize the comprehensive mechanical properties of HF-reinforced composites (HFRCs) by combining the performance advantages of the two types of fiber reinforcement, and the strength of the interface between HFs and polyurethane (PU) plays a crucial role in whether the advantages of the hybrid structure can be fully achieved. In addition, the mechanical properties of the composite were significantly enhanced, and the structural advantages of the hybrid structure were further improved after HFs were modified by PVA-GO-OCNT hybrid coating. The hybrid effect on the tensile strength of HFRCs with CF as the core and GF as the shell changes from a negative hybrid effect (5.4%) before modification to a positive hybrid effect (4.3%). The hybrid effect in tensile failure strain of HFRCs with GF as the core and CF as the shell changes from a negative hybrid effect (2.1%) before modification to a positive hybrid effect (2.1%). Moreover, the interlaminar shear strength of HFRCs modified by PVA-GO-OCNT hybrid coating is significantly higher than that of unmodified HFRCs.

Electrochemical activation to enhance the volumetric performance of carbon nanotube electrodes

In recent years, the floating catalyst chemical vapor deposition (FCCVD) method has established itself as one of the most commercially viable methods to produce carbon nanotubes (CNTs). However, at the final stage of the FCCVD process, densification of the web of CNTs to form a sheet causes a significant loss in the active surface area of the CNTs. This loss of surface area reduces the density of active materials that can be infiltrated into the CNT sheet. Reducing the amount of active material in the sheet reduces the charge storage capacity and causes low volumetric performance for CNT sheet in energy storage applications. Here, we are reporting the use of an electrochemical activation technique to chemically functionalize the CNT surface and recover the lost surface area. Chemical functionalization separates the CNTs and thereby increases the density of active materials that can be integrated into the CNT sheet. In order to avoid deterioration of the CNT structure from excessive electrochemical activation, we have optimized the procedure by comparing the performance of four samples of CNT sheets prepared using different numbers of cycles of electrochemical activation (5, 10, 20, 40 cycles). The performance of the sheet was analyzed using specific capacitance measurement, electrochemical impedance spectroscopy (EIS) analysis, and UV-vis absorption spectroscopy. In addition, the Randle-Sevcik plot was used to select the CNTs with the largest activated surface area and electrochemical specific capacitance (150F/g). Further analysis such as x-ray photoelectron spectroscopy (XPS) was also carried out to unveil a 5% increase of the various oxygen-containing functional groups at the surface of the activated CNTs. Polyaniline (PANI) was then deposited on the surface of the electrochemically altered CNTs via an oxidation polymerization process to create a CNT-PANI composite material. A fully fabricated device with CNT-PANI electrodes and Polyvinylidene fluoride – 1-Ethyl-3-methylimidazolium tetrafluoroborate (PVDF-EMIMBF4) electrolyte showed a significant specific capacitance improvement over a device with Poly(vinyl alcohol) -Sulfuric acid (PVA-H2SO4) electrolyte. The PVDF-EMIMBF4 capacitor device had a volumetric energy density of 833.3 mu M/h/cm(3) at a current density of 0.5 mA/cm(2). The capacitor has good mechanical flexibility and high capacitance retention (75% after 5000 cycles), which show the advantages of the electrochemical activation method.

TEMPO-oxidized cellulose fibers from wheat straw: Effect of ultrasonic pretreatment and concentration on structure and rheological properties of suspensions

Cellulose and TEMPO-oxidized cellulose fibers (TOCF) from the wheat straw were prepared with ultrasonic and chemical treatments to investigate structure and functionalities. Sol-gel transition of TOCF suspensions has been investigated using rheology to unveil the roles of ultrasonic pretreatment and temperature at various concentration. It was found that TOCF extracted with or without ultrasonic pretreatment exhibit similar functional groups in FTIR. However, different crystal structures and thermal stabilities were revealed in XRD and TGA, respectively. The gelation was independent of the ultrasonic pretreatment, while the rheological properties were highly infuenced by the concentration and temperature of the TOCF suspensions. TOCF suspensions presented a strain thinning behavior in large amplitude oscillatory shear tests. Lissajous curves showed that the elastoplastic behavior was predominantly modulated by the fiber concentration and strain amplitude other than the ultrasonic pretreatment. These results could improve the understanding of the relationships between TOCF structure and rheological properties.

4-Methoxybenzylalcohol protects brain microvascular endothelial cells against oxygen-glucose deprivation/reperfusion-induced injury via activation of the PI3K/AKT signaling pathway

Damage to the blood-brain barrier (BBB) during the process of cerebral ischemic injury is a key factor that affects the treatment of this condition. The present study aimed to assess the potential effects of 4-methoxybenzyl alcohol (4-MA) on brain microvascular endothelial cells (bEnd.3) against oxygen-glucose deprivation/reperfusion (OGD/Rep) using an in vitro model that mimics in vivo ischemia/reperfusion injury. In addition, the present study aimed to explore whether this underlying mechanism was associated with the inhibition of pro-inflammatory factors and the activation status of the PI3K/Akt signaling pathway. bEnd.3 cells were subjected to OGD/Rep-induced injury before being treated with 4-MA, following which cell viability, lactate dehydrogenase (LDH) release and levels of nitric oxidase (NO) were detected by colorimetry, pro-inflammatory factors including tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-1 beta and IL-6, were detected by ELISA. The expression levels of occluding and claudin-5were evaluated by immunofluorescence staining. The expression levels of AKT, phosphorylated (p)-Akt, endothelial nitric oxide synthase (eNOS) and p-eNOS were also measured by western blot analysis. After bEnd.3 cells were subjected to OGD/Rep-induced injury, cell viability and NO levels were significantly decreased, whilst LDH leakage and inflammatory factor (TNF-alpha, IL-1 beta and IL-6) levels were significantly increased. Treatment with 4-MA significantly ameliorated cell viability, LDH release and the levels of NO and pro-inflammatory factors TNF-alpha, IL-1 beta and IL-6 as a result of OGD/Rep. Furthermore, treatment with 4-MA upregulated the expression of occludin, claudin-5, Akt and eNOS, in addition to increasing eNOS and AKT phosphorylation in bEnd.3 cells. These results suggest that 4-MA can alleviate OGD/Rep-induced injury in bEnd.3 cells by inhibiting inflammation and by activating the PI3K/AKT signaling pathway as a possible mechanism. Therefore, 4-MA can serve as a potential candidate for treating OGD/Rep-induced injury.

The role of family conflict in mediating impulsivity to early substance exposure among preteens

Objectives: Preadolescence substance exposure, which increases the risk of regular substance use, has been a public health concern. Although studies found that impulsivity is a predisposing factor of early substance exposure, the pathways through which impulsivity is associated with early substance exposure remain unclear. This study examined how family conflict mediates this association among U.S. preteens as family environment plays an essential role in pre-adolescent development. Methods: Respondents (N = 11,800, 9-10 years old) from the Adolescent Brain Cognitive Development (ABCD) Study Release 2.01 (July 2019) were included in this study. Generalized structural equation modeling was performed to investigate the mediation effects of family conflict on the associations between childhood impulsivity and early exposure to alcohol and tobacco use, controlling for covariates based on the Problem Behavior Theory. Results: Pre-adolescents with high impulsivity levels (>= 90th percentile) were more likely to report early alcohol and tobacco exposure (total effect: ORs = 1.49 and 1.70, respectively), where 4.13% and 12.41% of the associations, respectively, were meditated by family conflict (indirect effect: ORs = 1.02 and 1.07; Sobel test ps = 0.022 and 0.005, respectively). Conclusions: Family conflict mediates the associations between childhood impulsivity and early substance exposure among preteens, with higher impulsivity leading to more severe family conflicts that are, in turn, associated with a higher likelihood of early substance exposure. To prevent preteens with high impulsivity level from early use of substances, interventions may focus on reducing family conflicts such as parenting counseling that guides parents to strengthen conflict-resolution skills and create a stable home environment for preteens.

Tailoring Multistimuli Responsive Micropatterns Activated by Various Mechanical Modes

A versatile wrinkle-based micropatterned system with a film-substrate structure is proposed, which contains a hydrophilic film of polyvinyl alcohol or its composite with laponite and a hydrophobic substrate of polydimethylsiloxane or its composite with carbon black. The wrinkled system features high design flexibility and multistimuli responsiveness, which can be activated by various mechanical methods, including vertical press or scratch, gentle stretch-and-release, bend, or analogous magneto-mechanical and electro-mechanical modes. The resultant wrinkles possess 1) instantaneous and reversible strain/moisture/light responsive optical modulation; 2) tunable dynamics for the aforementioned strain/moisture/light response;3) tailorable amplitude/wavelength; 4) unique surface morphologies from the coupling of wrinkles and cracks; 5) excellent reversibility and durability. A variety of applications are demonstrated based on this system, including 1) a moisture erasable highly sensitive pressure responsive device and pattern replicator with a high fidelity; 2) a moisture erasable scratch/magneto-mechanical re-writable tablet; 3) an electro-mechanical controllable smart window with an ultra-sensitive strain responsive transmittance modulation and a low operating voltage; 4) various types of strain responsive, moisture erasable, and laser writable information recording/encryption devices. This work provides new routes for designing innovative wrinkled systems triggered by diverse mechanical fashions and can decode multiple environmental stimuli into optical signals for widespread application.

An undercover problem in the Muslim community: A qualitative study of imams’ perspectives on substance use

Background: Mainstream Islam prohibits alcohol and other drugs, yet substance use is prevalent in Muslim-American communities. Previous studies have not examined how imams, leaders of mosques, address substance use in their communities. This study aimed to explore imams’ perspectives and approaches toward Muslim Americans with substance use disorders (SUD). Methods: Qualitative study of imams in New York City recruited by convenience sampling. We conducted one-on-one semi-structured interviews to address how imams perceive and address substance use. Using an inductive thematic analysis approach, we created an initial coding scheme which was refined iteratively, identified prominent themes, and created an explanatory model to depict relationships between themes. Results: All imams described substance use within a shared underlying framework of religious prohibition of alcohol and other drugs. Their perceptions of individuals with SUD diverged between a focus on sin, shame, and social disruption vs. a focus on acceptance and forgiveness. Furthermore, imams diverged between conceptualizing their communities as comprising mosque-going individuals without SUD vs. broader communities that include individuals with SUD. While imams acknowledged how some imams’ judgmental language toward SUD may perpetuate stigma, they also identified therapeutic approaches toward SUD: non-judgmental engagement, encouragement of recovery, prayer, and referral to resources. Conclusions: This study is among the first to illustrate the range of perceptions and approaches to substance use among Muslim American imams. These perceptions have potentially divergent impacts-shaming or assisting individuals with SUD. An understanding of these complexities can inform provision of culturally competent care to Muslim-American patients with SUD.
