На підставі експлуатаційних даних двох свердловин, пробурених на території Міжнародного центру відновлювальної енергетики, визначена енергетична ефективність використання підземних вод перших від поверхні землі водоносних горизонтів для отримання теплоти та холоду в системах теплохладопостачання житлових будинків та будівель громадського призначення. Дослідні свердловини розташовані на відстані 11,5 м одна від одної, глибина яких складає 50 і 57 м відповідно. Під час проведення пробних відкачок одержані основні попередні експлуатаційні характеристики горизонту. Статичний рівень встановлюється на глибині 32,0 м, дебіт свердловин складає 2-3 м3/год., початкова температура підземних вод – 12 °С.
Були розкриті таки водоносні горизонти та комплекси: горизонт алювіально-делювіальних відкладень першої надзаплавної тераси, що складається кварцовими пісками з лінзами та проверстками суглинків і залягає на глибині від 8 до 12 м; водоносний комплекс у відкладах межигірської, берекської та новопетрівської світ олігоцен-міоцену (полтавська і харківська серії), який залягає на глибині від 32 до 50 м та створений з дрібно-зернистого піску; бучаксько-канівський водоносний горизонт, що залягає на глибині від 90 до 117 м і складається з мілкого та дрібно-зернистого піску.
Для оцінки можливості використання підземних вод з метою геотермального тепло- і хладопостачання використано водоносний горизонт полтавського і харківського віку, оскільки цей горизонт ізольований від поверхневих і грунтових вод потужною товщою (до 20 м) щільних глин, що забезпечує йому сталий режим фільтрації і стабільні гідрогеологічні параметри.
В роботі показано, що використання підземних вод як джерела низькопотенційної енергії для теплових насосів дозволяє отримати від свердловини в 7...10 разів більшу теплову потужність в порівнянні з традиційними теплонасосними системами на основі ґрунтових зондів. Запропоновано схему роботи теплонасосних агрегатів з ступінчастим спрацьовуванням температурного потенціалу підземних вод від + 12 °С до + 1 °С, що дозволяє майже в півтора рази підвищити енергетичну ефективність процесу генерування теплової енергії. Оцінено ефективність застосування підземних вод для кондиціонування приміщень в літній час. Показано, що для даних свердловин величина СОР процесу «пассивного» кондиціонування перевищує 25. Температуру в приміщенні можна знизити на 5 градусів. Кількість «холоду», яка може бути отримана від однієї свердловини, становить більше 10 кВт.
На підставі аналізу гідрогеологічних характеристик та режиму фільтрації перших від поверхні водоносних горизонтів вибрано найбільш придатний для створення систем геотермального тепло- і холодопостачання водносний комплекс та проведено розрахунки, які показали доцільність використання водоносного горизонту у відкладах межигірської, берекської та новопетрівської світ олігоцен-міоцену.

Introduction. Acinetobacter baumannii is a Gram-negative nosocomial pathogen that has the capacity to develop resistance to all classes of antimicrobial compounds. However, very little is known regarding its susceptibility to biocides (antiseptics and disinfectants) and capacity to form biofilms, particularly for Malaysian isolates.
Aim. To determine the susceptibility of A. baumannii isolates to commonly-used biocides, investigate their biofilm-forming capacities and the prevalence of biocide resistance and biofilm-associated genes.
Methodology. The minimum inhibitory concentration (MIC) values of 100 A. baumannii hospital isolates from Terengganu, Malaysia, towards the biocides benzalkonium chloride (BZK), benzethonium chloride (BZT) and chlorhexidine digluconate (CLX), were determined by broth microdilution. The isolates were also examined for their ability to form biofilms in 96-well microplates. The prevalence of biocide resistance genes qacA, qacE and qacDE1 and the biofilm-associated genes bap and abaI were determined by polymerase chain reaction (PCR).
Results. Majority of the A. baumannii isolates (43%) showed higher MIC values (> 50 µg/mL) for CLX than for BZK (5% for MIC > 50 µg/mL) and BZT (9% for MIC > 50 µg/mL). The qacDE1 gene was predominant (63%) followed by qacE (28%) whereas no isolate was found harbouring qacA. All isolates were positive for the bap and abaI genes although the biofilm-forming capacity varied among the isolates.
Conclusion. The Terengganu A. baumannii isolates showed higher prevalence of qacDE1 compared to qacE although no correlation was found with the biocides’ MIC values. No correlation was also observed between the isolates’ biofilm-forming capacity and the MIC values for the biocides.

Abstract. The short-chain fatty acid butyrate, either in unprotected or protected
form, is widely applied as a growth-promoting feed additive in poultry
nutrition; however, its possible effects on the carcass composition of broilers have not been fully elucidated. Further, lowering dietary crude protein (CP) levels
is an important issue in poultry farming, contributing to ecologically
beneficial lower nitrogen excretion. The main aims of this study were to test
how unprotected and protected forms of butyrate and decreased dietary CP
content with essential amino acid (lysine, methionine, threonine,
tryptophan) supplementation (“LP-EAA” diet) affect carcass parameters and the chemical composition of muscles in broilers. Ross 308 chickens were
randomized to seven groups (n=10/group) receiving adequate CP-containing
(normal protein, “NP”) or LP-EAA diets, both supplemented with or
without unprotected sodium butyrate, and NP diets with different forms
of protected sodium butyrate. Carcass traits were measured, and the chemical
composition of pectoral and femoral muscles was analyzed at the age of 6 weeks. Carcass weight was significantly increased by the LP-EAA diet and all
protected butyrate types tested, while the relative breast meat yield was
significantly higher in LP-EAA than NP groups and in both
unprotected and protected butyrate-supplemented chickens compared to
controls. The protein content of the femoral muscle was significantly decreased, but
its lipid content was significantly elevated by the LP-EAA diet and by
all types of butyrate addition. However, no changes were detected in the
chemical composition of pectoral muscle. In conclusion, breast meat
production can be effectively stimulated by dietary factors, such as by
reducing dietary CP content with essential amino acid supplementation and by
applying butyrate as a feed additive, while its chemical composition remains
unchanged, in contrast to the femoral muscle. The aforementioned nutritional
strategies seem to be the proper tools to increase carcass yield and to alter
meat composition of broilers, contributing to more efficient poultry meat
production.

Published: September 2019

Background:
We compared the following 30-day outcomes for total knee arthroplasty (TKA) and total hip arthroplasty in spinal anesthesia (SA) versus general anesthesia (GA) (1) mortality, (2) major and minor complication rates, and (3) discharge disposition.

Methods:
From 2011 to 2016, the American College of Surgeons National Surgical Quality Improvement Program database contained 45,871 SA total hip arthroplasties and 65,092 receiving GA. There were 80,077 SA TKAs and 103,003 GA TKAs. Adjusted multivariate logistic regression evaluated associations between anesthesia type and 30-day outcomes.

Results:
Anesthesia modality was not associated with 30-day mortality (P > 0.05). The GA cohorts were at a greater risk for any complication, major complications, and minor complications (P < 0.05). Patients who received GA were at an increased risk for nonhome discharge.

Conclusion:
Patients who undergo total joint arthroplasty with SA experience fewer 30-day complications and are less likely to have a nonhome discharge than those with GA.

The aim of this study was to investigate the ability of floating water hyacinth (Eichhornia crassipes) to survive under selected concentrations of sago mill effluent (SME) and determine the nutrient uptake by the plant. Phytoremediation at 10, 15, and 20% (VSME/Vwater) SME concentrations by water hyacinth was conducted under greenhouse conditions for 30 d in a batch type experiment. After 30 d of phytoremediation, the removal efficiency of chemical oxygen demand, ammonia and phosphorus from SME wastewater were (86.4% to 97.2%), (91.4% to 97.3%) and (80.4 to 97.2%), respectively. The results proved the efficiency of water hyacinth to polish SME wastewater.

Published: September 2019

AbstractAlthough flexible and multifunctional textiles are promising for wearable electronics and portable device applications, the main issue is to endow textiles with multifunctionalities while maintaining their innate flexible and porous features. Herein, a vacuum‐assisted layer‐by‐layer assembly technique is demonstrated to conformally deposit electrically conductive substances on textiles for developing multifunctional and flexible textiles with superb electromagnetic interference (EMI) shielding performances, superhydrophobicity, and highly sensitive humidity response. The formed leaf‐like nanostructure is composed of silver nanowires (AgNWs) as the highly conductive skeleton (vein) and transition metal carbide/carbonitride (MXene) nanosheets as the lamina. The presence of MXene protects AgNWs from oxidation and enhances the combination of AgNWs with the fabric substrate, and the transformation of its functional groups leads to self‐derived hydrophobicity. The flexible and multifunctional textile exhibits a low sheet resistance of 0.8 Ω sq−1, outstanding EMI shielding efficiency of 54 dB in the X‐band at a small thickness of 120 µm, and highly sensitive humidity responses, while retaining its satisfactory porosity and permeability. The self‐derived hydrophobicity with a large contact angle of >140° is achieved by aging the hydrophilic MXene coated silk. The wearable multifunctional textiles are highly promising for applications in intelligent garments, humidity sensors, actuators, and EMI shielding.

AbstractRechargeable aluminum‐ion batteries have drawn considerable attention as a new energy storage system, but their applications are still significantly impeded by critical issues such as low energy density and the lack of excellent electrolytes. Herein, a high‐energy aluminum‐manganese battery is fabricated by using a Birnessite MnO2 cathode, which can be greatly optimized by a divalence manganese ions (Mn2+) electrolyte pre‐addition strategy. The battery exhibits a remarkable energy density of 620 Wh kg−1 (based on the Birnessite MnO2 material) and a capacity retention above 320 mAh g−1 for over 65 cycles, much superior to that with no Mn2+ pre‐addition. The electrochemical reactions of the battery are scrutinized by a series of analysis techniques, indicating that the Birnessite MnO2 pristine cathode is first reduced as Mn2+ to dissolve in the electrolyte upon discharge, and AlxMn(1−x)O2 is then generated upon charge, serving as a reversible cathode active material in following cycles. This work provides new opportunities for the development of high‐performance and low‐cost aqueous aluminum‐ion batteries for prospective applications.

Published: September 2019

AbstractTo achieve the full potential of scalable and cost‐effective organic electronic devices, developments are being made in both academic and industry environments to move toward continuous solution‐processing techniques that make use of safe and environmentally benign “green” solvents. In this work, the first example of a transistor device that is fully solution processed using only green solvents is demonstrated. This achievement is enabled through a novel multistage cleavable side chain process that provides aqueous solubility for semiconducting conjugated polymers, paired with aqueous inkjet printing of PEDOT:PSS electrodes, and a solution deposited ion gel electrolyte as the dielectric layer. The resulting organic electrochemical transistor devices operate in accumulation mode and reach maximum transconductance values of 1.1 mS at a gate voltage of − 1 V. Normalizing the transconductance value to the channel dimensions yields gm/W = 2200 S m−1 (µC* = 22 F cm−1 V−1 s−1), making these devices suitable for a range of applications requiring small signal amplification such as transistors, biosensors, and ion pumps. This new material design and device process paves the way toward scalable, safe, and efficient production of organic electronic devices.

Published: September 2019

AbstractSurface functionalization is considered to be an effective and versatile strategy to tailor intrinsic electronic and optoelectronic properties of 2D materials. In this work, surface‐decorated few‐layer antimonene is synthesized by a one‐step electrochemical exfoliation and synchronous halogenation method in halogen‐containing an ionic liquid–based electrolyte at room temperature. The prepared halogenated antimonene nanosheets are composed of oxygen‐ and halogen‐decorated amorphous and crystalline domains. The structural reconstructions and evolutions of halogenated antimonene are further revealed by ab initio molecular dynamics simulations and first‐principles calculations. The band structures and optical properties of antimonene can be tailored after amorphization and surface functionalization, depending on the reactivity of different halogens. The photoresponse performance of the halogenated antimonene is further evaluated by photoelectrochemical measurement. Exhibiting self‐powered photoresponse behavior, their photocurrent density increases with the increases of external bias potential and light intensity. This work proposes a new idea of tuning the optoelectronic properties of 2D materials by synchronous halogenation in the facile one‐step electrochemical synthesis process. Benefiting from this facile synthesis procedure, the halogenation of antimonene may shed light on chemical functionalization of other 2D materials for electronic and optoelectronic applications.

Published: September 2019

AbstractA transparent Schottky photodiode is constructed based on a SrTiO3 (STO) wafer, in which nickel‐coated silver nanowires (AgNi NWs) are proposed as the high‐work‐function transparent electrode. A selective photoresponse to harmful short‐wavelength blue (SWB) light is generated owing to the proper bandgap of STO, and the AgNi NWs effectively strengthen the photovoltaic behavior, resulting in an ultrafast response speed (trise/tfall = 7 µs/115 µs) and photocurrent of 16–38 nA under a 0 V bias. Meanwhile, the complete device maintains a transparency of ≈60% almost over the entire visible light region and blocks 96.7% UVA and >99.9% UVB. The combination of bias‐free SWB detection and transparent UV shielding is readily applicable to protect against light pollution. Furthermore, this work proposes a considerable method to modulate the work function of transparent Ag NW electrodes by surface coating, which provides inspiration for the development of transparent electrode materials with different work functions.

AbstractUsing high‐capacity and metallic Li‐free lithium sulfide (Li2S) cathodes offers an alternative solution to address serious safety risks and performance decay caused by uncontrolled dendrite hazards of Li metal anodes in next‐generation Li metal batteries. Practical applications of such a cathode, however, still suffer from low redox activity, unaffordable cost, and poor processability of infusible and moisture‐sensitive Li2S. Herein, these difficulties are addressed by developing a molecular cage–engaged strategy that enables low‐cost production and interfacial engineering of Li2S cathodes for rechargeable Li2S//Si cells. An efficient chemisorption–electrocatalytic interface is built in extremely nanostructured Li2S cathodes by harnessing the confinement/separation effect of metal–organic molecular cages on ionic clusters of air‐stable, soluble, and low‐cost Li salt and their chemical transformation. It effectively boosts the redox activity toward Li2S activation/dissociation and polysulfide chemisorption–conversion in Li‐S batteries, leading to low activation voltage barrier, stable cycle life of 1000 cycles, ultrafast current rate up to 8 C, and high areal capacities of Li2S cathodes with high mass loading. Encouragingly, this highly active Li2S cathode can be applied for constructing truly workable Li2S//Si cells with a high specific energy of 673 Wh kg−1 and stable performance for 200 cycles at high rates against hollow nanostructured Si anode.

AbstractThe construction of a novel 3D self‐supported integrated NixCo2−xP@NC (0 < x < 2) nanowall array (NA) on Ni foam (NF) electrode constituting highly dispersed NixCo2−xP nanoparticles, nanorods, nanocapsules, and nanodendrites embedded in N‐doped carbon (NC) NA grown on NF is reported. Benefiting from the collective effects of special morphological and structural design and electronic structure engineering, the NixCo2−xP@NC NA/NF electrodes exhibit superior electrocatalytic performance for water splitting with an excellent stability in a wide pH range. The optimal NiCoP@NC NA/NF electrode exhibits the best hydrogen evolution reaction (HER) activity in acidic solution so far, attaining a current density of 10 mA cm−2 at an overpotential of 34 mV. Moreover, the electrode manifests remarkable performances toward both HER and oxygen evolution reaction in alkaline medium with only small overpotentials of 37 mV at 10 mA cm−2 and 305 mV at 50 mA cm−2, respectively. Most importantly, when coupling with the NiCoP@NC NA/NF electrode for overall water splitting, an alkali electrolyzer delivers a current density of 20 mA cm−2 at a very low cell voltage of ≈1.56 V. In addition, the NiCoP@NC NA/NF electrode has outstanding long‐term durability at j = 10 mA cm−2 with a negligible degradation in current density over 22 h in both acidic and alkaline media.

AbstractMass interfacial processes have been considered as one of the crucial factors supporting fundamental research. Due to the low cost and conceptual simplicity, significant advancements have been achieved in the development of methodologies based on piezoelectric devices for in situ determination of mass changes on the surfaces of deposited materials under various conditions. The introduction of nanomaterials for designing sensors and monitoring systems becomes essential to create advanced detection systems for selective sensing of toxic analytes for environmental remediation. The integration of materials with predesignated nanostructures into sensor devices, such as surface acoustic wave (SAW), quartz crystal microbalance (QCM), and QCM with dissipation (QCM‐D) monitoring, has led to an immense progress in the sensing applications of toxic target analytes at the nanogram range. Here, an overview is introduced of recent advancement in the fabrication of piezoelectric devices for the interfacial mass sensing of targeted chemical vapors and ions through combination with nanoporous materials including mesoporous materials carbon‐based nanomaterials, metal–organic frameworks (MOFs), MOF‐derived nanoporous carbons, Prussian blue (PB) and its analogues (PBA), zeolites and related materials. Challenges and future prospect are also summarized by the advanced QCM technique associated with properties of nanostructured materials.
