The use of biomaterials as photothermal substrates as well as their modification for solar interface water evaporation, self-desalination and water pollutant removal is currently considered a highly cost-effective strategy. Herein, we introduce an evaporator based on typical biomaterial (wood), which obtained through delignification, followed by freeze-drying treatment, then surface carbonization, and finally metal organic frameworks (MOFs) material loading, for effective solar-interfacial evaporation. The outstanding feature of the developed evaporator is that it exhibits excellent ultraviolet to near-infrared light absorbing capacity and high heat conversion efficiency, which can realize the rapid increase of the evaporator’s surface temperature within 10 min. On other hand, the high hydrophilicity of the evaporator ensures rapid water transportation. Therefore, the evaporation rate of Fe-MOF decorated wood reaches a value up to 1.81 kg m-2 h-1 and exhibits an evaporation efficiency of 89% under 1 Sun-illumination. In the self-desalination capacity test, the composite evaporator owing 4 cm2 surface area achieved an efficient removal of 1 g of NaCl in 1 hour. In the simulated sewage purification experiment, the purification rate of tetracycline, methyl orange, and rhodamine B solutions reaches 93.2%, 100%, and 99.3%, respectively, indicating that the developed evaporator can be considered as potential candidate for environmental safety applications. © 2023, The Authors.

The electron localized heptazine units make it difficult to separate photoinduced electeron-hole pairs for graphitic carbon nitride (g-C 3 N 4 ), which limits the application prospect of graphitic-like carbon nitride. Changing inherent NC3 bridging mode of in-plane heptazine units and built more electron channel could be a reasonable strategy. Herein, "carbon patches" were introduced to stitch heptazine units, high speed electron transfer path were thus constructed due to delocalized p orbital electron in "carbon patches" as a result. Simultaneously, interlayers’ high speed electron transfer channel were also constructed by distorted molecular layer because of presence of large electronegative interstitial phosphorus atoms. Such photoinduced electron-holes’ spatial separation in-plane and interlayers were built concurrently and confirmed by XANES and DFT calculation for the first time. The resulted PCCN v series photocatalysts exhibited superior photon absorption capability, excellent charge carriers’ separation kinetics, good O 2 molecule adsorption as well as activation capability, the resulted abundant reactive radicals contributed to petroleum hydrocarbons photocatalytic degradation significantly. This work shed light on efficient separation of photoinduced excition for carbon nitride in photocatalysis, simultaneously presented a promising candidate non-metal photocatalytic environmental materials for marine oil spill remediation. © 2022, The Authors.

The series includes two parts, articulating the two novel avenues of research on intelligent fault diagnosis (FD) for nonlinear feedback control systems. In Part I of the series, we design a novel FD paradigm by elaborating an invertible neural network (INN) for feedback control systems. With the aid of a left manifold, the core idea behind the INN-based FD scheme is (i) formulation of residual generator used for FD as a projection of system data onto the null space that has the same dimension as system outputs, (ii) in a topological space, elaboration of a homeomorphism that delivers an invertible relationship between system outputs and residual signals when the system input is given, (iii) skillful introduction of both the master and slave objective functions to achieve system/parameter identification with information loseless property. Comparing with the existing FD approaches, the three superior strengths of the proposed FD scheme deserving mentation are: 1) it specializes in nonlinear feedback control systems, 2) it can effectively avoid the overfitting problem when approximating or learning nonlinear system dynamics, and 3) control theory guides the whole design, ensuring the interpretability of the learning process. Finally, two studies on nonlinear systems demonstrate the feasibility of the invertible left manifold (ILM)-based FD strategy. Part I would contribute to the future development of machine learning (ML)based system identification and explainable FD approaches, and also benefits the right manifold-based FD designs in the Part II. © 2023, CC BY.

The article presents the issue of scale deposits in sanitary installations. Scale contributes to improper operation of sanitary devices and leads to their degradation. Scale build-up in pipes and measuring elements results in higher water consumption due to inaccurate estimation of this resource consumption. The consequence is that devices based on process automation do not work properly due to disturbances in the actual water flow. The formation of deposits also leads to economic and ecological losses, as sanitary installations elements have to be replaced, which affects the increased use of raw materials and the generation of waste. This is not in line with current trends and global objectives related to circular economy. Scale also results in increased energy consumption and reduced energy efficiency. This is due to the resistance of the flows and the increased work of the pumps. Scale has insulating properties, which results in less efficient heat transfer. In this stady, a mathematical model was developed to detect the formation of scale deposits in sanitary installations. On this basis, it is possible to control the quality status of sanitary installation components. In this way, by taking appropriate action at an early stage of the formation of deposits, it can extend the life of the installation. Having information on scale deposits, it will help avoid wasting water and lead to more accurate measurement of water flows. This is important for the proper operation of devices such as heat pumps, where their operation is automated and requires precise measurements of the energy processes taking place. Scale is a significant problem for households, and also for factories or public institutions that are exposed to hard water environments. © 2021 International Multidisciplinary Scientific Geoconference.

Efficient discrimination of ions and small neutral contaminants remains a challenge for polyamide thin-film nanocomposite (TFN) water separation membranes due to the presence of interfacial defects and particle-agglomeration-induced nonselective voids in the polyamide thin layer. In this work, postsynthetic modification of (3-glycidyloxypropyl)triethoxysilane on MIL-101(Cr)-NH 2 MOF filler nanoparticles was performed to form a stable particle suspension in the organic monomer solution during interfacial polymerization for membrane formation, suppressing particle agglomeration, while trimesoyl chloride induced in situ crosslinking between filler particles and polyamide was utilized to address the phase compatibility and interfacial issues at the filler–polyamide interface. The resulting TFN membranes show high NaCl, MgCl 2 , Na 2 SO 4 , and MgSO 4 rejections of 99.0–99.6% at 150 psi with a water permeance of 1.3 L m –2 h –1 bar –1 , Compared to the thin-film composite (TFC) control membrane, the incorporation of the MOF particles yields a 53.0% and 24.5% increase in water permeance and NaCl rejection. Importantly, the TFN membranes also exhibit excellent rejections to small neutral contaminants such as PEG200 (99.2% rejection) and boric acid (89.0% rejection at a pH value of 7.5) at a relatively low pressure of 150 psi, which is higher than the respective value obtained by the commercial Dow SW30XLE TFC control membrane at the same conditions. The outstanding long-term performance stability revealed the robust structure of the MOF TFN membranes for water purification. Our results demonstrate a facile strategy to effectively control particle agglomeration and interfacial defects in polyamide TFN membranes by manipulating the surface chemistry of the filler nanoparticles, which leads to the successful fabrication of effective TFN membranes with molecular level size-exclusion selectivity. © 2022, The Authors.

Collective dynamics of confined colloids are crucial in diverse scenarios such as self-assembly and phase behavior in materials science, microrobot swarms for drug delivery and microfluidic control. Yet,fine-tuning the dynamics of colloids in microscale confined spaces is still a formidable task due to the complexity of the dynamics of colloidal suspension and to the lack of methodology to probe colloids in confinement. Here, we show that the collective dynamics of confined magnetic colloids can be finely tuned by external magnetic fields. In particular, the mechanical properties of the confined colloidal suspension can be probed in real time and this strategy can be also used to tune microscale fluid transport. Our experimental and theoretical investigations reveal that the collective configuration characterized by the colloidal entropy is controlled by the colloidal concentration, confining ratio and external field strength and direction. Indeed, our results show that mechanical properties of the colloidal suspension as well as the transport of the solvent in microfluidic devices can be controlled upon tuning the entropy of the colloidal suspension. Our approach opens new avenues for the design and application of drug delivery, microfluidic logic, dynamic fluid control, chemical reaction and beyond.

The cochlea has long been the subject of investigation in various research fields due to its intriguing spiral architecture and unique sensing characteristics. One of its most interesting features is tonotopy, the ability to sense acoustic waves at different spatial locations based on their frequency content. In this work, we propose a novel design for a tonotopic resonator, based on a cochlea-inspired spiral, which can discriminate the frequency content of elastic waves without the use of sub-wavelength resonators. The structure is the result of an optimization process to display a uniform distribution of displacement maxima along its centreline for frequencies spanning nearly a two-decade range. Numerical simulations are performed to demonstrate the concept and experimental measurements to validate it on a 3D printed structure. The resulting frequency-dependent distribution is also shown to be a viable means to discriminate signals with various frequency components. We also show that for appropriate parameter ranges, the tonotopic behaviour can be inverted, i.e., lower frequencies can be made to concentrate in narrower regions, as happens in the real cochlea. The harnessed tonotopic features can be used as a fundamental principle to design structures with applications in areas such as non-destructive testing and vibration attenuation. © 2022, The Authors.

In this work, we propose a novel design for a tonotopic resonator, based on a cochlea-inspired spiral.

Numerical simulations are performed to demonstrate the concept, which is also confirmed experimentally on a 3D printed structure.
