AbstractThe conventional membranes used for separating oil/water emulsions are typically limited by the properties of the membrane materials and the impact of membrane fouling, making continuous long‐term usage unachievable. In this study, a filtering electrode with synchronous self‐cleaning functionality is devised, exhibiting notable antifouling ability and an extended operational lifespan, suitable for the continuous separation of oil/water emulsions. Compared with the original Ti foam, the in situ growth of NiTi‐LDH (Layered double hydroxide) nano‐flowers endows the modified Ti foam (NiTi‐LDH/TF) with exceptional superhydrophilicity and underwater superoleophobicity. Driven by gravity, a rejection rate of over 99% is achieved for various emulsions containing oil content ranging from 1% to 50%, as well as oil/seawater emulsions. The flux recovery rate exceeds 90% after one hundred cycles and a 4‐h filtration period. The enhanced separation performance is realized through the “gas bridge” effect during in situ aeration and electrochemical anodic oxidation. The internal aeration within the membrane pores contributes to the removal of oil foulants. This study underscores the potential of coupling foam metal filtration materials with electrochemical technology, providing a paradigm for the exploration of novel oil/water separation membranes.

AbstractTransition metal dichalcogenides (TMDs) exhibit excellent electronic and photoelectric properties under pressure, prompting researchers to investigate their structural phase transitions, electrical transport, and photoelectric response upon compression. Herein, the structural and photoelectric properties of layered ZrS2 under pressure using in situ high‐pressure photocurrent, Raman scattering spectroscopy, alternating current impedance spectroscopy, absorption spectroscopy, and theoretical calculations are studied. The experimental results show that the photocurrent of ZrS2 continuously increases with increasing pressure. At 24.6 GPa, the photocurrent of high‐pressure phase P21/m is three orders of magnitude greater than that of the initial phase at ambient pressure. The minimum synthesis pressure for pure high‐pressure phase P21/m of ZrS2 is 18.8 GPa, which exhibits a photocurrent that is two orders of magnitude higher than that of the initial phase and displays excellent stability. Additionally, it is discovered that the crystal structure, electrical transport properties and bandgap of layered ZrS2 can also be regulated by pressure. This work offers researchers a new direction for synthesizing high‐performance TMDs photoelectric materials using high pressure, which is crucial for enhancing the performance of photoelectric devices in the future.

AbstractModern cryptography based on computational complexity theory is mainly constructed with silicon‐based circuits. As DNA nanotechnology penetrates the molecular domain, utilizing molecular cryptography for data access protection in the biomolecular domain becomes a unique approach to information security. However, building security devices and strategies with robust security and compatibility is still challenging. Here, this study reports a time‐controlled molecular authentication strategy using DNAzyme and DNA strand displacement as the basic framework. A time limit exists for authorization and access, and this spontaneous shutdown design further protects secure access. Multiple hierarchical authentications, temporal Boolean logic authentication, and enzyme authentication strategies are constructed based on DNA networks'good compatibility and programmability. This study gives proof of concept for the detection and protection of bioinformation about single nucleotide variants and miRNA, highlighting their potential in biosensing and security protection.

Published: April 2024

AbstractThe performance of electrochemical batteries is intricately tied to the physicochemical environments established by their employed electrolytes. Traditional battery designs utilizing a single electrolyte often impose identical anodic and cathodic redox conditions, limiting the ability to optimize redox environments for both anode and cathode materials. Consequently, advancements in electrolyte technologies are pivotal for addressing these challenges and fostering the development of next‐generation high‐performance electrochemical batteries. This review categorizes perspectives on electrolyte technology into three key areas: additives engineering, comprehensive component analysis encompassing solvents and solutes, and the effects of concentration. By summarizing significant studies, the efficacy of electrolyte engineering is highlighted, and the review advocates for further exploration of optimized component combinations. This review primarily focuses on liquid electrolyte technologies, briefly touching upon solid‐state electrolytes due to the former greater vulnerability to electrode and electrolyte interfacial effects. The ultimate goal is to generate increased awareness within the battery community regarding the holistic improvement of battery components through optimized combinations.

AbstractThis study focuses on the synthesis and characterization of SiO2–CaO–P2O5–Na2O nanofiber bioglass (BG) tablets using cellulose nanofibers (CNFs) as a template and starch binders. Three types of tablets are prepared: sago starch binder tablets, xanthan gum binder tablets, and dry press tablets (used as a control). The tablets are investigated for their physicochemical structure, mechanical properties, in‐vivo bioactivity, and antibacterial efficiency using various characterization techniques such as Fourier transform infrared (FTIR), field emission scanning electron microscope (FESEM), XRD, ICP, etc. The results indicate the formation of a hydroxyapatite (HA) layer on the surface of the tablets after immersion in simulated body fluid (SBF) for 28 days, demonstrating their bioactivity. FESEM analysis reveals the formation of HA crystals with different morphologies, including oval‐shaped crystals in sago tablets and needle‐like crystals in xanthan tablets. The binder tablets exhibit higher Ca/P ratios compared to the press‐dried tablets. Among the binder tablets, sago starch tablets show superior mechanical properties. Additionally, the binder tablets display efficient antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. These findings highlight their potential as promising candidates for bone tissue engineering applications.

Published: April 2024

AbstractThe current study presents a novel approach to starch modification using infrared dry heat treatment (IR‐DHT). IR‐heating at 200 °C allows one to reduce the processing time to 15 min and does not lead to irreversible amorphization of starch structure. Upon IR‐DHT, an increase in density of starch granules from 1.4888 ± 0.0005 to 1.5038 ± 0.0005 g cm−3 is observed. The crystallinity degree of the starch exposed in water at 20 °C after IR‐DHT does not change compared to the crystallinity of native starch hydrated at the same temperature. However, the exposure in excess of water of native potato starch at 45 °C induces an increase of crystallinity up to 81% (along with a significant increase in the intensity of the d100 reflection), while heat‐treated starch exposed in water at the same temperature has reduced crystallinity (RC = 39%). In addition, the concentration of soluble carbohydrates released during the exposure process (45 °C, excess of water) increases by an order of magnitude for heat‐treated starch compared to the native sample. Hence, IR‐DHT may become a promising way to influence the processes of acid and enzymatic hydrolysis and control starch properties, such as pasting, solubility, and digestibility.

Published: April 2024

AbstractNative starch Pickering stabilizer without chemical modification has attracted research interest in food field. However, the behaviors of starch particles at interface are seldom studied. In this paper, ultrafine starch particles (USPs) are grounded with a planetary ball mall from various starch species down to 1–2 µm in size. USP and starches are used to prepare Pickering emulsions. With size decrease, USP has more negative zeta potentials, stronger hydrogen bonds, better hydrophilicity, and better emulsifying abilities than their counterparts of starches. Millet starch has better emulsion stability than OSA modified starch. Glutinous USP outperforms in stabilization due to higher emulsion height and no oil phase separation. USP behaves differently at interface or in water phase, which is attributed to starch species, amylose and amylopectin contents, and gelatinization. This work can inspire the behavior investigation of starch particles in nano/micrometers at interface during storage.

AbstractThe formation of algae blooms can influence uncontrolled growth, causing hazards to aquatic ecosystems. The attention of microalgae wastewater treatment is gathering significance in bio‐energy conversion, resulting in environmental sustainability. Gasification technology is found to improve energy conversion with improved environmental sustainability. The novel research is to treat microalgae wastewater via hydrothermal gasification process with the assistance of a potassium hydroxide catalyst (KOH). During the gasification process, the gasification time is varied from 10, 20, and 30 min under a higher gasification temperature of 900°C is maintained throughout the gasification process. Effect of gasification processing time with KOH catalyst action on the percentage of molar fractions including carbon monoxide (CO), carbon dioxide (CO2), hydrogen (H2) and methane (CH4), lower heating value (LHV), syngas H2 yield, and gasification efficiency of hydrothermal gasification process for microalgae wastewater are experimentally investigated. The results of the present investigation are exposed with higher processing time with maximum gasification temperature processed with KOH catalyst offered maximum H2 fraction of 59%, reduced CH4 and LHV of 15% and 10 MJ/Nm3, optimum H2 yield of 22 mol/kg, and attained maximum gasification efficiency of 55%, respectively. The optimum gasification process parameters, including a 30‐min processing time with a higher gasification temperature of 900°C gained H2, will be suggested for energy/alternative fuel applications.

Published: April 2024

AbstractThis study aimed to present the effect of the mediums to dissolve chitosan on the morphology of obtained chitosan microspheres and find a suitable medium for preparing porous chitosan microspheres for adsorption application. Three acidic solutions, including acetic, ascorbic, and citric acids, were used to dissolve chitosan flakes. The prepared chitosan microspheres were characterized by scanning electron microscopy (SEM), X‐ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET) analysis. The microspheres’ inner morphologies depended on the mediums to dissolve chitosan. The highest porosity of the chitosan microspheres was obtained using an acetic solution, while the sample showed the highest crystallinity prepared in a citric solution. Besides, the chitosan microspheres prepared in the acetic solution had the most efficient methylene blue (MB) removal from water. Its maximum MB sorption capacity was 79.37 mg g−1. The non‐linear pseudo‐second‐order kinetic model was the best kinetic fit for the interaction of MB with those chitosan microspheres. Moreover, the prepared microspheres showed good cyclic stability and easy recovery, suggesting their high feasibility in wastewater treatment.

AbstractThermoplastic poly(ether ester) elastomer (TPEE) is a highly flammable material with severe melt‐dropping, which greatly limits its range of applications. Here, black phosphorus nanosheets (BPs) and aluminum diethylphosphinate (ADP) were used to improve the fire safety of TPEE for the first time. Results demonstrated that ADP/BPs as a synergistic combination exhibits good dispersity and excellent flame retardancy, also has minimal negative effects on the mechanical performances of the TPEE composites. By comparing TPEE/ADP‐22 and TPEE/ADP‐10/BPs‐4, the introduction of BPs significantly reduced the addition of ADP while keeping the material at the higher vertical burning grade, ~54.5% reduction in ADP usage. Compared with neat TPEE, TPEE/ADP‐10/BPs‐4 fulfilled V‐0 level, avoided dripping, and the limiting oxygen index value increased to 34.0%. Moreover, TPEE/ADP‐10/BPs‐4 performed the best in cone calorimetry test, both the peak heat release rate and total heat release reduced the largest, by 44.2% and 25.3%, respectively. The detailed studies of the flame‐retardant mechanism found that ADP/BPs showed the fire‐retardant impact of the condensed phase and gaseous phase. This work expands BPs in the flame‐retardant application and could facilitate to prepare the anti‐dripping flame‐resistant TPEE.Highlights
BPs as an efficient flame retardant were added into TPEE for the first time.
ADP/BPs as a synergistic combination has an excellent fire‐retardant effect.
The introduction of BPs significantly reduced the addition of ADP.
TPEE/ADP‐10/BPs‐4 showed the highest FPI and the lowest FGI.
ADP/BPs has lowest negative effects on the mechanical performances of matrix.

Tiebout, Coase and urban scaling
Authors: Webster Chris 
Published: April 2024

AbstractA growing body of urban research takes a natural science perspective on systems of cities as self-organising human clusters. From a systems perspective, this work, particularly the growing number of city scaling studies, introduces a determinism to studies of city size, efficiency and performance that may not sit well with regional science and urban economic planning models. It finds that agglomeration economies seem to follow regular scale-free power laws that reflect competitive dynamics within an entire interacting human system of cities and that a city’s performance is therefore statistically bounded by the whole system. Where does this leave empirical models of individual city performance and behavioural models of urban political economy that underpin them? The paper links two seminal economic models of the 20th century that were motivated to demonstrate the possibility of preference revelation for the ‘unpriceables’ that give cities their value. Tiebout’s and Coase’s models of social order both concern natural clustering principles, governed by voting with feet, voice and price. Voting with feet is a much more animalistic social ordering mechanism than voting with voice and the paper introduces the idea of scale-free Tieboutian models—natural science models of revealed preference for local public expenditure.
Multiparameter signal-to-noise ratio optimization for end milling cutting conditions of aluminium alloy 5083
Authors: Kechagias John 
Published: April 2024

AbstractSurface integrity problems during selective material removal processes are a very common limitation for process productivity and part quality, especially in difficult-to-machine materials like 5083 aluminium alloy (AA), which is known for its remarkable performance in extreme environments. In general, tuning the cutting-part material properties with cutter geometry and cutting parameters can optimize surface texture, increase parts accuracy and resistance in corrosion, and eliminate process noise and energy waste. This work is an experimental study of surface parameter optimization during finish end milling of an AA5083 under a specific range of three cutting parameters with an optimized two-flute carbide cutter by previous work. So, twenty-seven experiments were run having varied the radial depth of cut (RDOC), feed rate (f), and cutting speed (S). Surface roughness parameters (Ra and Rt) were measured in the direction of cutting speed at three different distances by the upper edge. The signal-to-noise (SN) ratios have been calculated, and the process was optimized following the analysis of means. Then, additive models with linear interactions were fitted on SN ratios, and the analysis of variances and residual normality plots were utilized to validate the models’ goodness. The SN approach and analysis of means conclude that 0.5 mm RDOC, 6000 rpm speed, and 0.082 mm/tooth feed optimize the process and can effectively predict the Ra and Rt responses. The newly produced machinability data can benefit further applications of AA5083 in industrial applications such as shipbuilding and vehicle bodies.
