Kegiatan Program Kemitraan Masyarakat (PKM) Eks-Lokalisasi Dolly di Kelurahan Putat Jaya Kecamatan Sawahan Surabaya ini merupakan kegiatan berkelanjutan (sustainable) pengabdian masyarakat bermetode service learning sejak tahun 2016. Mitra dengan ragam latar belakang pendidikan berbeda memiliki pekerjaan beragam pula mulai dari wiraswasta, pekerja lepas, pengangguran hingga pegawai negeri. Pendapatan warga menurun ketika penutupan lokalisasi ini dilakukan ditambah kondisi pandemi covid-19, padahal hingga saat ini masih banyak warga yang belum memiliki jamban sehat yang di lengkapi dengan septic tank yang merupakan salah satu sumber penyakit yang ada di lingkungan yang sanitasinya buruk. Tujuannya kegiatan PKM ini adalah untuk ikut mensukseskan dan berpartisipasi aktif dalam pelaksanakan program Campus Goes To Kampung dalam rangka pemberdayaan warga terdampak eks-lokalisasi di kota Surabaya yang merupakan mitra kegiatan. Metode kegiatan ini dibagi menjadi 3 tahap. Tahap pertama adalah tahap pra pelaksanaan dimana dilakukan survei area tersebut. Kemudian, dilanjutkan dengan tahap pelaksanaan pembuatan WC dan septic tank. Terakhir, yaitu tahap paska pelaksanaan berupa focus group discussion bersama warga dan monitoring dengan penyebaran kuesioner sebanyak 26 responden mengenai tingkat kepuasan pelaksaan kegiatan PKM ini. Hasilnya adalah seluruh warga (100%) mendapatkan manfaat dari kegiataan dan warga juga puas dikarenakan lingkungannya telah diberdayakan. Sejak kegiatan ini dilakukan dari 315 keluarga belum memiliki jamban sehat, kini tinggal 87 kepala keluarga saja yang belum memilikinya.

AbstractThe effect of heteroalkyl (‐XR, X = Se, S, O) substitution on a series of molecular semiconductors having a 3,3′‐diheteroalkyl‐2,2′‐bithiophene (XBT) central core is studied. Thus, the selenotetradecyl (‐SeC14H29) SeBT core is investigated by end‐functionalization with two dithienothiophene (DTT), thienothiophene (TT), and thiophene (T) units to give SeBTs 1–3, respectively, for molecular π‐conjugation effect examination. Furthermore, the selenodecyl (‐SeC10H21) and selenohexyl (‐SeC6H13) SeBT cores end‐capped with DTTs to give SeBTs 1B and 1C, respectively, are synthesized for understanding ‐SeR length effects. To address systematically the impact of the chalcogen heteroatom, the newly developed selenoalkyl SeBTs are compared with the previously reported thiotetradecyl (‐SC14H29) DDTT‐SBT (4) and the new tetradecyloxy (‐OC14H29) DDTT‐OBT (5). When fabricating organic field effect transistors by the solution‐shearing method, the devices based on the tetradecylated DDTT‐SeBT (1) exhibit the highest mobility up to 4.01 cm2 V−1 s−1, which is larger than those of the other SeBT compounds and both DDTT‐SBT (4) (1.70 cm2 V−1 s−1) and DDTT‐OBT (5) (9.32 × 10−4 cm2 V−1 s−1). These results are rationalized by a combination of crystallographic, morphological, and microstructural analysis.

AbstractOxygen releasing biomaterials can facilitate the survival of living implants by creating environments with a viable oxygen level. Hydrophobic oxygen generating microparticles (HOGMPs) encapsulated calcium peroxide (CPO) have recently been used in tissue engineering to release physiologically relevant amounts of oxygen for several weeks. However, generating oxygen using CPO is mediated via the generation of toxic levels of hydrogen peroxide (H2O2). The incorporation of antioxidants, such as catalases, can potentially reduce H2O2 levels. However, the formulation in which catalases can most effectively scavenge H2O2 within oxygen generating biomaterials has remained unexplored. In this study, three distinct catalase incorporation methods are compared based on their ability to decrease H2O2 levels. Specifically, catalase is incorporated within HOGMPs, or absorbed onto HOGMPs, or freely laden into the hydrogel entrapping HOGMPs and compared with control without catalase. Supplementation of free catalase in an HOGMP‐laden hydrogel significantly decreases H2O2 levels reflecting a higher cellular viability and metabolic activity of all the groups. An HOGMP/catalase‐laden hydrogel precursor solution containing cells is used as an oxygenating bioink allowing improved viability of printed constructs under severe hypoxic conditions. The combination of HOGMPs with a catalase‐laden hydrogel has the potential to decrease peroxide toxicity of oxygen generating tissues.

AbstractSurface‐enhanced Raman scattering (SERS) has received widespread attentions in biological detection since its single‐molecule sensitivity. The SERS substrate with numerous highly active hotspots can effectively capture target, whose precise fabrication is undoubtedly extremely challenging but attractive. Therefore, this work tries to achieve an ultrasensitive SERS platform based on the accurate regulations of its composition, structure, and distribution. Specifically, ordered CdS/MoS2@Au nanoparticles (AuNPs) nanopillars are fabricated by the aid of atomic layer deposition (ALD). Optimal selection and precise control of ALD cycles in MoS2 fabrication can accurately adjust the pillar diameter and obtain the most favorable minimum gap (8 nm) between pillars, which is advantageous to form multidimensional and high‐density hotspots thus generating a 9.4‐times promotion as compared with the control group. On the other hand, calculated analysis shows that appropriate spacing distance between pillars slightly larger than analyte molecule can produce considerable capillary force, which is advantageous to capture analyte and anchor it in the high‐charged‐density region for higher self‐activation of hotpots. Based on the above two favorable factors, a linear detection window from 10 × 10−18 to 1 × 10−8 m with an ultralow detection limit of 0.82 × 10−18 m for miRNA‐182 is achieved.

AbstractChemical functionalization of molecular 2D materials toward the assembly of hierarchical functional nanostructures is of great importance for nanotechnology including areas like artificial photocatalytic systems, nanobiosensors, or ultrafiltration. To achieve the desired functionality of 2D materials, these need to be characterized down to the nanoscale. However, obtaining the respective chemical information is challenging and generally requires the application of complementary experimental techniques. Here, the synthesis and chemical characterization of hierarchically assembled molecular nanosheets based on ≈1 nm thin, molecular carbon nanomembrane (CNM) and covalently grafted, single‐molecule layer cobalt(III) catalysts for the light‐driven hydrogen evolution reaction (HER) is demonstrated. X‐ray photoelectron spectroscopy (XPS) and tip‐enhanced Raman spectroscopy (TERS) to access both the transversal and longitudinal chemical information of the synthesized nanosheets with nanometer resolution are employed. TERS and XPS data provide detailed information on the average and local surface distribution of the catalyst as well as mechanistic details of the grafting reaction. The proposed approach represents a general route toward a nanoscale structural analysis for a variety of molecular 2D materials—a rapidly growing materials class with broad prospects for fundamental science and applications.

AbstractStructural reconstruction is a process commonly observed for Cu‐based catalysts in electrochemical CO2 reduction. The Cu‐based precatalysts with structural complexity often undergo sophisticated structural reconstruction processes, which may offer opportunities for enhancing the electrosynthesis of multicarbon products (C2+ products) but remain largely uncertain due to various new structural features possibly arising during the processes. In this work, the Cu2O superparticles with an assembly structure are demonstrated to undergo complicated structure evolution under electrochemical reduction condition, enabling highly selective CO2‐to‐C2+ products conversion in electrocatalysis. As revealed by electron microscopic characterization together with in situ X‐ray absorption spectroscopy and Raman spectroscopy, the building blocks inside the superparticle fuse to generate numerous grain boundaries while those in the outer shell detach to form nanogap structures that can efficiently confine OH− to induce high local pH. Such a combination of unique structural features with local reaction environment offers two important factors for facilitating C−C coupling. Consequently, the Cu2O superparticle‐derived catalyst achieves high faradaic efficiencies of 53.2% for C2H4 and 74.2% for C2+ products, surpassing the performance of geometrically simpler Cu2O cube‐derived catalyst and most reported Cu electrocatalysts under comparable conditions. This work provides insights for rationally designing highly selective CO2 reduction electrocatalysts by controlling structural reconstruction.

AbstractRecording electrophysiological information such as brain neural signals is of great importance in health monitoring and disease diagnosis. However, foreign body response and performance loss over time are major challenges stemming from the chemomechanical mismatch between sensors and tissues. Herein, microgels are utilized as large crosslinking centers in hydrogel networks to modulate the tradeoff between modulus and fatigue resistance/stretchability for producing hydrogels that closely match chemomechanical properties of neural tissues. The hydrogels exhibit notably different characteristics compared to nanoparticles reinforced hydrogels. The hydrogels exhibit relatively low modulus, good stretchability, and outstanding fatigue resistance. It is demonstrated that the hydrogels are well suited for fashioning into wearable and implantable sensors that can obtain physiological pressure signals, record the local field potentials in rat brains, and transmit signals through the injured peripheral nerves of rats. The hydrogels exhibit good chemomechanical match to tissues, negligible foreign body response, and minimal signal attenuation over an extended time, and as such is successfully demonstrated for use as long‐term implantable sensory devices. This work facilitates a deeper understanding of biohybrid interfaces, while also advancing the technical design concepts for implantable neural probes that efficiently obtain physiological information.

AbstractMetals such as Sb and Bi are important anode materials for sodium‐ion batteries because they feature a large capacity and low reaction potential. However, the accumulation of stress and strain upon sodium storage leads to the formation of cracks and fractures, resulting in electrode failure upon extended cycling. In this work, the design and construction of BixSb1−x bimetallic alloy films with a compositional gradient to mitigate the intrinsic structural instability is reported. In the gradient film, the top is rich in Sb, contributing to the capacity, while the bottom is rich in Bi, helping to reduce the stress in the interphase between the film and the substrate. Significantly, this gradient film affords a high reversible capacity of ≈500 mAh g−1 and sustains 82% of the initial capacity after 1000 cycles at 2 C, drastically outperforming the solid‐solution counterpart and many recently reported alloy anodes. Such a gradient design can open up the possibilities to engineering high‐capacity anode materials that are structurally unstable due to the huge volume variation upon energy storage.

AbstractCarbon nanotubes (CNTs) are a rapidly maturing emerging technology for next‐generation energy‐efficient digital Very‐Large‐Scale‐Integrated (VLSI) systems. However, a major remaining challenge facing CNT field‐effect transistors (CNFETs) are metallic CNTs, causing incorrect logic functionality and increased leakage power. As no CNT synthesis technique demonstrates a reliable path toward manufacturing 99.99% semiconducting CNTs (s‐CNT; required purity for VLSI systems), significant work focuses on solution‐based sorting of CNTs (selectively removing metallic CNTs post‐synthesis). Yet, there lacks both well‐controlled comparisons carefully optimizing key processing parameters simultaneously (CNT synthesis sources, polymer additive used for selective sorting, etc.), as well as statistically significant electrical transistor characterization sample sizes to form concrete conclusions. Here, >90 000 CNFETs (totaling >90 million CNTs) are fabricated and characterized to demonstrate the following key advances: 1) systematic exploration of the impact of different combinations of CNT synthesis sources and polymer additives on the electrical performance of transistors (analyzing on‐current, off‐current, on off ratio, and threshold voltage) to find the best combination, 2) how the optimization and choice of the CNT source can be decoupled from that of the polymer, and 3) an optimal CNT solution that achieves >99.99% s‐CNT purity using electrical measurements, meeting the requirement for VLSI systems.

Published: April 2022

AbstractAn exact anisotropic star model with a linear barotropic equation of state and with Finch‐Skea potential is constructed within the framework of pure Lovelock gravity. A comparison with the corresponding Einstein model in a suitable limit is easily deduced. Evidently higher curvature effects induced by the Lovelock contributions generate lower densities, pressures, surface tensions, and anisotropy factors when compared to its Einstein counterpart. The maximum moment of inertia is attained for the Einstein case and hence it may be inferred that Lovelock effects soften the equation of state. The model satisfies various stability tests.

Published: April 2022

AbstractPrevious studies reported that several amino acids had strong antioxidant activity in vegetable oils under frying conditions. In this study, amino acids were converted to their sodium or potassium salts, and a heating study was conducted with 5.5 mM amino acid salts in soybean oil (SBO) at 180°C. Sodium salts of amino acids including alanine, phenylalanine, and proline and disodium glutamate had significantly stronger antioxidant activity than the corresponding amino acids, and potassium salts had stronger antioxidant activity than sodium salts. Potassium salts of alanine and phenylalanine more effectively retained tocopherols in SBO than the corresponding amino acids during heating. Phenylalanine potassium salt had stronger antioxidant activity than phenylalanine in other vegetable oils including olive, high oleic soybean, canola, avocado, and corn oils. Phenylalanine potassium salt at 5.5 mM more effectively prevented oil oxidation than tert‐butyl hydroquinone, a synthetic antioxidant, at its legal concentration limit (0.02%) indicating its feasibility as a new antioxidant for frying.

Published: April 2022

AbstractMuch research has assumed that Notch codes one protein. Then the protein will be cleaved into two parts and regenerates a heterodimers receptor to construct Notch signal pathways to regulate development in the past three decades. Here, we show that Notch in brown planthopper is a complex alternatively spliced gene has at least three transcriptional start sites, four exon skips, and 21 transcriptional endpoints that uses these to form variants and codes a series of proteins. When used dsRNAs to suppression different regions of the full‐length variant NlNF resulted in a similar phenotype. Insects were molting after treatment, sensation circles on antennas near to root decayed, bristles on wings shortened, thickened or disappeared, accompanied by thickening veins and blades of fore‐wing apex regions thickened. These results suggested that Notch influenced developmental of sensation circles, bristles, veins, and blades in nymph late periods. This study has deepened our understanding of Notch.

AbstractThrough the special situation like the COVID‐2019 lockdown, interactive techniques play a prime role in the study process. The strategy of lockdown ways of higher education was provided in Ukraine as well as in other countries since March 2020. Our investigation was performed at the Department of Biochemistry and Medical Chemistry of Dnipro State Medical University during the first lockdown of COVID‐19 from March to June 2020. The main aim of the research was the evaluation of the students' attitudes to studying Biochemistry using Google classrooms and Moodle. Four hundred and sixty‐three students studying in English, French, and Ukrainian took part in the survey. Our results reveal that majority of the students found Google classrooms and Moodle as useful e‐learning tools. However, questions dealing with the technical issues of using the Google classrooms on laptops and mobile phones and submitting the replies to the Google classrooms cause difficulties among the students.

AbstractBackgroundHypertension is a well‐established risk factor for cognitive impairment, brain atrophy, and dementia. However, the relationship of other types of hypertensions, such as isolated hypertension on brain health and its comparison to systolic‐diastolic hypertension (where systolic and diastolic measures are high), is still relatively unknown. Due to its increased prevalence, it is important to investigate the impact of isolated hypertension to help understand its potential impact on cognitive decline and future dementia risk. In this study, we compared a variety of global brain measures between participants with isolated hypertension to those with normal blood pressure (BP) or systolic‐diastolic hypertension using the largest cohort of healthy individuals.MethodsUsing the UK Biobank cohort, we carried out a cross‐sectional study using 29,775 participants (mean age 63 years, 53% female) with BP measurements and brain magnetic resonance imaging (MRI) data. We used linear regression models adjusted for multiple confounders to compare a variety of global, subcortical, and white matter brain measures. We compared participants with either isolated systolic or diastolic hypertension with normotensives and then with participants with systolic‐diastolic hypertension.ResultsThe results showed that participants with isolated systolic or diastolic hypertension taking BP medications had smaller gray matter but larger white matter microstructures and macrostructures compared to normotensives. Isolated systolic hypertensives had larger total gray matter and smaller white matter traits when comparing these regions with participants with systolic‐diastolic hypertension.ConclusionsThese results provide support to investigate possible preventative strategies that target isolated hypertension as well as systolic‐diastolic hypertension to maintain brain health and/or reduce dementia risk earlier in life particularly in white matter regions.
