A self-powered sensor based on a bare Ti mesh with polarity-switchable output • Combined experimental and COMSOL simulation validates hybrid triboelectric and streaming-potential mechanism. • Demonstrates multi-parameter sensing: flow velocity, volume, ionic solutions, and natural water types • Higher-valence cations (Al 3+ > Mg 2+ > Na + ) produce significantly enhanced signals. The growing demand for standalone self-powered sensing systems is driving significant interest in developing devices that can harvest energy from ambient moisture and natural water sources while simultaneous providing sensing capabilities. This study presents a cost-effective, industrially scalable self-powered sensor based on a simple Ti-based mesh integrated within a pressure-adjustable container. The electrical output of this device can be rapidly polarity-switched merely by toggling the water flow through the Ti-based mesh, without any surface modification or external energy input. Notably, the device demonstrates multi-parameter sensing capabilities, enabling detection of water flow velocity, flow volume, ionic solutions of varying valences and concentrations, and even different types of natural water. The underlying mechanisms are elucidated through combined experimental and computational analyses, revealing that the electrical signals originate from hybrid triboelectric and streaming-potential effects. This work establishes a design paradigm for high-performance, Ti-based self-powered sensors with polarity-switchable characteristics, offering promising applications in environmental monitoring and water quality assessment.

Titanium (Ti) implants are widely used for treating bone fractures, but their clinical success is often limited by high failure rates due to the excessive osteoclastogenic activation of osteoclast precursor cells (OPCs) at the implantation site, particularly in patients with osteoporosis. Notably, the excessive osteoclastic differentiation of OPCs potently disrupts the osteogenesis-angiogenesis coupling to promote osteoclast-mediated osteolysis while dismantling the pro-osteogenic type H vascular niches, resulting in elevated risk of implant destabilization. To address this issue, here we report a biomineralization-tuned extracellular matrix (ECM)-mimetic biomineralized coating (TCC@Har-CaG) to enable redox rewiring of OPCs for promoting new bone formation. Specifically, we employed collagen-I as the substrate material to fabricate the stimuli-responsive biomineralized coating for the cooperative delivery of antioxidative gallic acid (GA) and osteoclast precursor cell inhibitor Harmine. The TCC@Har-CaG coating could sustainably release GA after implantation to effectively relieve reactive oxygen species (ROS) stress at the osteoporotic bone defects, which could synergize with Harmine to efficiently induce OPC quiescence and restore osteogenesis-angiogenesis coupling, thus cooperatively promoting new bone generation. This study presents a potential tactic for addressing osteoporotic bone fractures in clinical settings.

RuO 2 electrodes are widely used in electrocatalytic oxidation due to their excellent conductivity. However, their excessively high catalytic activity toward the oxygen evolution reaction (OER) results in low selectivity for hydroxyl radicals (·OH), which limits their application in the treatment of recalcitrant organic pollutants. This study proposes a strategy to simultaneously enhance electrode conductivity and the oxygen evolution potential (OEP) by modulating the RuO 2 -TiO 2 solid solution structure. Through precise control of Ti doping levels and calcination temperature via a sol-gel method, the structure-performance relationships among coating microstructure, crystal structure, and electrochemical behavior were systematically analyzed. Results show that when the Ti doping ratio is Ru: Ti= 1:2.5 and calcination is performed at 600 °C, a well-crystallized RuO 2 -TiO 2 solid solution is formed. This structure significantly reducing the charge transfer resistance and increasing the OEP by approximately 100 mV. Fluorescence and quenching experiments further confirmed that under this solid solution structure, with the ·OH fluorescence intensity increased by approximately ninefold compared to the undoped electrode. The electrode demonstrated significant advantages in MB degradation, achieving >95% decolorization within 30 min, with energy consumption as low as 5.65 kWh·t -1 , and exhibited stability more than ten times greater than that of conventional RuO 2 electrodes. This study provides a new perspective for enhancing the electrocatalytic performance of RuO 2 electrodes from the standpoint of solid solution structural regulation, offering a theoretical basis and a feasible pathway for developing efficient and low-cost anode materials for electrochemical advanced oxidation processes.

30CNQDs@NMT/PMS achieved almost complete degradation of malathion within 30 min simulated sunlight irradiation. • CNQDs was integrated successfully to promote the charge separation efficiency as electron bridges and enhance the adsorption energy of PMS for activation revealed by DFT. • •OH and •SO 4 – were generated to attack the identified sites of malathion computed via Fukui function. • The intermediate products in the photocatalytic process were less toxic than malathion assessed by T.E.S.T. Malathion, an organophosphate pesticide widely used in agricultural fields across the world, has raised environmental concerns due to its persistence and toxicity. Thus, a novel photocatalyst was synthesized by integrating carbon nitrogen quantum dots (CNQDs) onto NH 2 -MIL-125(Ti) (NMT) via a solid-phase thermal polycondensation method. It was demonstrated that CNQDs served a dual function as electron bridges to facilitate charge separation and as peroxymonosulfate (PMS) adsorption activation sites substantially enhancing the photocatalytic activity, which was revealed by Density Functional Theory (DFT). Under simulated sunlight, 30CNQDs@NMT achieved nearly 100 % malathion removal within 30 min via PMS activation, exhibiting 8.1 times higher than NMT. While •OH and •SO 4 – acted as the dominant reactive species to attack the malathion sites. The toxicity of the intermediate products assessed by T.E.S.T. (Toxicity Estimation Software Tool) were much lower than malathion. Moreover, 30CNQDs@NMT performed effectively in real water matrices, demonstrating its potential for practical environmental applications.

In this research, MIL-53(Fe)@BiOBr/TCN/Ti photoanode was created using the secondary silica sol drop coating method, and assembled with Cu cathode to form photocatalytic fuel cell (PFC) to degrade rhodamine B and generate electricity. The resulting PFC has high visible light response and photocatalytic activity . It has a rhodamine B degradation efficiency of 92.19%, a maximum power density of 6.2 μW cm −2 , and a maximum photocurrent density of 0.11 mA cm −2 . Its strong photocatalysis capabilities benefits from the wider light absorption range and lower charge carrier recombination rate of the photoanode. The double Z-scheme heterojunction formed among BiOBr, MIL-53(Fe) and TCN in the composite catalyst of the photoanode provide more transfer channels for photogenerated e − and encourage the separation of e − -h + pairs. ∙OH and ∙O - 2 are the main active substances for rhodamine B degradation. This study offers a novel approach to the development of high-efficiency photoanodes for PFC.

The brazed joint of sapphire transparent ceramic and Kovar alloy was prepared using AgCuTi and AgCuTiB composite filler, and the main focus was the effect of B element on the wetting behavior, interface composition and joint mechanical performance. The reliable joint of sapphire transparent ceramic and Kovar alloy was obtained by vacuum brazing with AgCu28-6Ti-0.45B (wt%) composite filler. The typical interfacial structure of the joint brazed at 825 °C for 10 min was determined as sapphire/Ti 3 Cu 3 O/Ag(s,s) + Cu(s,s) + disperse TiB/TiFe 2 + TiNi 3 /Kovar. The results showed that the addition of B could contributed to an optimized interfacial structure via (i) in-situ forming fine TiB whisker reinforcement phase and refining the interface structure and (ii) reducing the diffusion degree of alloy side elements to inhibit the generation of brittle phase, and the maximum shear strength of the joint with AgCu28-6Ti-0.45B (wt%) reached 125 MPa more than twice the joint without B additive. On the other hand, the wetting experiment showed that the addition of B as a solid particle decreased the fluidity of the composite filler, and when the addition of B was excessive, no dense TiB whiskers were produced in the interface. This study provides ideas for the optimization and improvement of sapphire composite connection, and points out that the generation of reinforcing phase is accompanied by the reduction of fluidity, so it is necessary to reasonably control the proportion of reinforcing phase.

Innovative solar-driven heterostructure photocatalysts are promising for removing the organic contaminants in the water environment. In this work, a sequence of well-defined Z-scheme Ti-Ga co-doped ZnO/g-C 3 N 4 (TGZ/CN) heterostructure photocatalysts were developed via a simple sol–gel method and the single-phase dispersion method in order to realize the cooperative improvement from the Ti/Ga co-doping and construction of heterostructure. The synthesized samples were analyzed by a variety of characterization techniques, and the photocatalytic activity was assessed by photodegradation of methylene blue (MB) under visible light irradiation. Compared to the ZnO and g-C 3 N 4 , the TGZ/CN composite demonstrated higher photocatalytic performance for the degradation of MB indicating an efficient photocatalytic degradation rate of 95.4% in 105 min under visible light. Moreover, the TGZ/CN photocatalyst exhibited excellent stability after five cycles of MB photodegradation. Furthermore, the as-prepared composites’ possible photocatalytic mechanism was discussed in detail. The improved photocatalytic performance primarily resulted from the effectively reduced band gap of ZnO after Ti/Ga co-doping and the facilitated separation of photoexcited e − /h + pairs caused by the construction of Z-scheme heterojunction. This work offers novel insights in developing hybrids with highly efficient photocatalytic activity towards future environmental applications. Graphical abstract

The oxygen evolution kinetics of industrial copper electrodeposition is slow, resulting in low electrocatalytic activity and high energy consumption. In this work, a quaternary composite of carbon coated active particles containing Mn, Co and Ce were prepared (Mn-Co 3 O 4 /CeO 2 @C), and Ti/Sb-SnO 2 /PbO 2 electrode doped with these active particles was prepared by co-electrodeposition. The microstructure and chemical composition of the electrode was characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffractometry (XRD). Linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS) and Tafel polarization curve (Tafel) were used to study the electrochemical properties of anode materials. The results showed that the doping of Mn-Co 3 O 4 /CeO 2 @C active particles promoted the crystal transition of PbO 2 , decreased the average grain size, and the doping of Ce increases the average valence state of Co. The modified titanium electrode showed excellent catalytic activity of the oxygen evolution reaction (OER) characteristics. The overpotential of the doped Ti/Sb-SnO 2 /PbO 2 anode was only 453 mV when the current density was 20 mA cm −2 in 0.5 M H 2 SO 4 solution, which is 508 mV lower than that of the undoped Ti/Sb-SnO 2 /PbO 2 anode. In simulated copper electro-deposition experiments, the cell voltage was reduced by about 400 mV, compared to the undoped Ti/Sb-SnO 2 /PbO 2 electrode.

Stress shielding is caused by the mismatch of stiffness between bone and implant materials, which may give rise to bone resorption and loosening, thereby causing implantation failure. There is a huge gap between Young's modulus of human bone and low Young's modulus β Ti alloys. A porous structure design can achieve the target of low Young's modulus, and thus achieve the matching between human bone and implant materials. However, a suitable space holder (SH) that can be applied at high temperatures and sintering pressure has not been reported. In this study, the TiZrNbTa/Ti titanium matrix composite (TMC) with high strength and large ductility was used as scaffold materials and combined the SH technique with the spark plasma sintering (SPS) technique to obtain a porous structure. A novel space holder, i.e., MgO particles was adopted, which can withstand high-temperature sintering accompanied by a sintering pressure. The porous TiZrNbTa/Ti with 40 vol.% MgO added exhibits a maximum strength of 345.9 ± 10.4 MPa and Young's modulus of 24.72 ± 0.20 GPa, respectively. It possesses higher strength compared with human bone and matches Young's modulus of human bone, which exhibits great potential for clinical application.

The low electron–hole separation in the photoanode generally restricts the visible light response of photocatalytic fuel cell (PFCs). In this study, 5% NH2-MIL-125/g-C3N4/Bi2O3/Ti photoanode was synthesized and assembled with a PFC with Cu cathode to degrade rhodamine B and generate electricity. With visible light irritation, the maximum photocurrent density, maximum power density, and degradation rate of the PFC were 0.59 mA cm−2, 29.88 μW cm−2, and 97.48% (1 h), respectively. The major active species in the PFC were h+, ˙O2−, and ˙OH. The good performance of the PFC was ascribed to the formation of a double Z-type heterojunction in the 5% NH2-MIL-125/g-C3N4/Bi2O3/Ti photoanode so that the photoelectrons of NH2-MIL-125 and Bi2O3 directly combine with the photoholes of g-C3N4, making the photoholes of NH2-MIL-125 and Bi2O3 and the photoelectrons of g-C3N4 directly or indirectly involved in the RhB degradation process and generating electricity. Thus, the separation rate of the e−–h+ pairs in the photoanode and the capability of the PFC are greatly improved.

Using TiN-Ti-AlN as the binder, polycrystalline cubic boron nitride (PCBN) composites containing Y 2 O 3 and not containing Y 2 O 3 were prepared under high temperature and ultra-high pressure conditions, respectively. X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to analyze the phase composition, microstructure and surface crack morphology of the composite material. At the same time, the compactness, microhardness and bending strength of the composite material were tested. The research results show that the phase composition of PCBN sample is mainly composed of BN, TiB 2 , TiN, AlN and Y 2 O 3 at an ultra-high pressure of 5.5 GPa and a temperature of 1500 °C. With the increase of Y 2 O 3 content, the relative density of PCBN first increases and then decreases, and the changes in mechanical properties also tend to be similar. As the content of Y 2 O 3 increases, it can be seen that the peak intensity of the main peak of TiB 2 also increases, indicating that the addition of Y 2 O 3 promotes the reaction between cBN and Ti. When the Y 2 O 3 content is 3.6%, PCBN has the best comprehensive mechanical properties, with a microhardness of 34.56 GPa and a bending strength of 890 MPa.

In order to enhance the photoelectric conversion efficiency of a photoanode and broaden its light absorption range, a ZnIn 2 S 4 /UiO-66/TiO 2 /Ti composite photoanode was developed. The maximum photocurrent density of the prepared photoanode is 2.56 mA cm −2 at 1.2 V (versus SCE), which is 1.79 times higher than that of ZnIn 2 S 4 /TiO 2 /Ti. The rhodamine B (RhB) removal rate, short-circuit current density and maximum power density of a photocatalytic fuel cell (PFC) constructed with the ZnIn 2 S 4 /UiO-66/TiO 2 /Ti photoanode and a Cu cathode are 98.01%, 0.22 mA cm −2 and 16.97 μW cm −2 respectively. The enhancement of the PFC performance is mainly attributed to the extremely good energy band matching and nano-size interface contact between ZnIn 2 S 4 and UiO-66. The existence of UiO-66 can be as an electronic transmission bridge, which not only facilitates the rapid transfer and utilization of photogenerated electrons, but also improves the adsorption ability of the photoanode for RhB molecules.
