Omnidirectional detection is widely used in optical tracking systems, omni-directional cameras and optical field measurements and so on. However, the planar structures of ultraviolet (UV) photodetectors (PDs) limit their application in omnidirectional detection. In this work, the NiO nanosheets were fabricated on a titanium (Ti) wire substrate by hydrothermal method and then assembled a photoelectrochemical (PEC) type UV photodetector (PD). Under ultraviolet (UV) irradiation of 35 mW cm −2 @ 365 nm, the PD exhibits a stable photocurrent of 1.53 μA cm −2 and repeatable switching cycles. Also, the PD presents fast response and recovery times of 0.074 s and 0.130 s, respectively. Particularly, the PD based on NiO@Ti possesses excellent response for rotation angles in the range from 0° to 360° under UV light irradiation .

Ni-Cr-Co-Ti-V-Al high-entropy alloy coating on Ti-6Al-4V was synthesized by laser surface alloying. The coating is composed of a B2 matrix and (Co, Ni)Ti 2 compounds with few β-Ti phases. Focused ion beam technique was utilized to prepare TEM sample and TEM observations agree well with XRD and SEM results. The formation of HEA phases is due to high temperature and rapid cooling rate during laser surface alloying. The thermodynamic parameters, ΔH mix , ΔS mix and δ as well as Δχ, should be used to predict the formation of the BCC solid solution, but they are not the strict criteria. Especially when Δχ reaches a high value (≥ 10%), BCC HEA will be partially decomposed, leading to the formation of (Co, Ni)Ti 2 compound phases.

The co-precipitation behaviour of a simulated Al 2 (SO 4 ) 3 –TiOSO 4 –Na 2 SiO 3 solution that imitated the lixivium of Ti-bearing blast furnace slag (Ti-slag) leached by sulphuric acid was investigated in this study. Various chemical analyses were employed to study the selective precipitation of multiple target components. Based on the high-added-value applications of Ti-slag, a new method was developed to prepare aluminium titanate composites from titanium-containing silicates. The findings demonstrate that the onsets of Ti and Al precipitation occur at pH values of 3.5 and 5.0, respectively, followed by Si precipitation. The particle sizes of the co-precipitates were greatly influenced by the precipitants, pH and the initial Al/Ti mole ratio. The results also show that the precipitation ratio of Ti, Al and Si generally increases with the pH and temperature, regardless of the Al/Ti mole ratio. The Si-O-Al, Ti-O-Al, and Ti-O-Si bonds that were formed were dependent on the pH and the initial Al/Ti mole ratio. There was a synthesis path for β -Al 2 TiO 5 (AT) from the solid-state reaction between rutile and α -Al 2 O 3 at 1362.5°C. The AT composites were successfully prepared by sintering the co-precipitates at 1450°C, which exhibited good thermal stability as estimated by the XRD measurements of the sample annealed at 1200°C for 4 hours.

In proteomics, phosphorylation is an important process for protein post-translational modification (PTM), which greatly improves the diversity of proteomes. The PTM regulates almost all physiological and pathological processes such as signal transduction , cell division, proliferation, differentiation and metabolism. The abnormal expression of protein phosphorylation is also associated with cellular metabolic disorders and a range of diseases. However, in mass spectrometry-based phosphorylated peptideomics studies, phosphorylated peptide signals were inhibited by a high abundance of non-phosphorylated peptides; thus, highly selective enrichment was required. In this study, a newly designed material named Fe 3 O 4 @MIL(Fe/Ti) was synthesized using a layer-by-layer self-assembly technique that coats the surface of magnetic oxide nanospheres with bimetallic MOF of iron and titanium. The synergistic synthetic coating of the bimetallic MOF gives the material a large surface area and excellent hydrophilicity , which endow the nanoparticles with excellent phosphopeptide enrichment ability, high selectivity (β-casein/BSA molar ratio 1:500), a low detection limit (3 fmol), high recovery rate (85%), strong binding capacity, size exclusion ability, and ideal batch-to-batch repeatability. For comparison, we used Fe 3 O 4 @MIL(Fe/Ti) and two single-metal MOF materials Fe 3 O 4 @MIL-100(Fe) and Fe 3 O 4 @MIL-125(Ti), to enrich α-casein in the middle. Thus, the iron-titanium bimetallic MOF can not only enrich all the phosphorylated peptides enriched by Fe 3 O 4 @MIL-100(Fe) and Fe 3 O 4 @MIL-125(Ti), but can also specifically enrich four phosphorylated peptides. Encouraged by the excellent results of characterization and standard protein enrichment, we used this material to analyze human serum and found that bimetallic materials can effectively enrich all four phosphorylated peptides and exclude high molecular proteins. These experimental results indicate that the novel bimetallic MOF is a good candidate to analyze protein phosphorylation in complex samples.

Hydrogels characterized by a three-dimensional polymer network are promising vehicles for oral colon-targeted drug delivery, yet conventional systems relying on intragastric cross-linking agents face clinical limitations. Here, we present a cross-linker-independent oral in situ hydrogel (CCS/CMC-Na) functionalized with Ti₃C₂ MXene nanosheets for optimized inflammatory bowel disease (IBD) therapy. The CCS/CMC-Na hydrogel exhibits a liquid-gel state transition in simulated gastric fluids while gradually returning to a liquid state in simulated colonic fluids, enabling precise targeting of inflamed colon tissues and protecting encapsulated drugs from gastric degradation. The integration of Ti₃C₂ not only enhances mechanical stability but also introduces multifunctional therapeutic capabilities: repairing all levels of intestinal barriers, reducing oxidative stress, inhibiting apoptosis, modulating Regulatory T cells (Treg)/T helper 17 (Th17) cell differentiation and NF-κB/IκB inflammatory pathway, and remodeling the intestinal microbiota. In murine models of acute and chronic colitis, Ti₃C₂@CCS/CMC-Na significantly alleviates disease severity, outperforming clinical first-line drug 5-ASA. Crucially, this system eliminates the need for dual-tube administration, simplifies dosing protocols, and demonstrates excellent biocompatibility over 50 days, addressing key challenges in current IBD therapies. By integrating precise targeting, multimodal therapeutic actions, and scalable fabrication, Ti₃C₂@CCS/CMC-Na represents great clinical translational potential, offering a safer and more effective treatment option for IBD.

Based on the thermal energy storage and solar-thermal conversion of solid-liquid phase change materials (PCMs), they feature exceptional potential for energy-saving thermal insulation and solar energy utilization in buildings. However, the inherent low thermal conductivity, susceptibility to leakage and poor solar absorption of PCMs seriously restrict their practical applications. In this work, composite PCMs were fabricated by encapsulating paraffin with diatomite porous ceramics (DC) featuring hierarchical pore structures prepared by foaming and freeze-drying. Excellent sunlight absorption and solar-thermal conversion were achieved by spraying a Ti 3 C 2 T x coating on the DC-paraffin surface. The as-prepared DC 3 -PA with 55.85 % loading on paraffin possessed a satisfactory thermal storage capacity of 112.1 J/g, maintained excellent stability, and improved the thermal conductivity by 107.25 %. The solar-thermal conversion and storage efficiency of DC 3 /T-PA is as high as 95.24 % under 200 mW/cm 2 light intensity attributed to the large broad-band solar absorption and strong localized surface plasmon resonance (LSPR) effect of the Ti 3 C 2 T x coating. This strategy combining hierarchical porous structured ceramic encapsulation and Ti 3 C 2 T x coating surface modification was employed for obtaining high-performance shape-stable composite PCMs, which was expected to achieve potential applications in building energy efficiency, solar energy utilization, and thermal management.

As an emerging class of enzyme-mimicking nanomaterials, nanozymes provide a novel strategy for eliminating water pollutants. Their catalytic efficiency can be significantly boosted by light irradiation, owing to its controllability and activation potential. However, the synergy between nanozyme and photocatalysis remains underexplored, especially for degrading pharmaceuticals and personal care products (PPCPs), and requires deeper mechanistic understanding. This study achieves a breakthrough in carbamazepine (CBZ) degradation by pioneering a hydrogen bond-bridged polyethyleneimine (PEI) modified nitrogen-doped titanate nanotubes (NTNTs) catalyst that uniquely combines photocatalytic and enzyme-mimicking functions in a single system. Nitrogen dopant incorporation into titanate nanotubes (TNTs) extends light absorption range, facilitates charge carrier separation, and elevates photocatalytic performance. Simultaneously, Ti-N interactions modify electronic configurations, conferring peroxidase-like characteristic to NTNTs. Branched PEI hydrogen-bonded to NTNTs further expands the specific surface area, multiplies active sites, extends visible-light response, and serves as an electron conduit for enhanced interfacial charge transfer. Moreover, the activated hydrogen peroxide (H 2 O 2 ) facilitates Ti(III)/Ti(VI) redox cycling, which not only amplifies hydroxyl radical production but also establishes a self-sustaining catalytic loop, thereby enhancing the photo-enzyme synergistic effect through continuous generation of reactive oxygen species. The catalyst removes 98 % CBZ in 30 min with 66.5 % TOC reduction and maintains good reusability and stability. This work advances the design of multifunctional catalytic systems by integrating photocatalysis and nanozyme for sustainable water treatment.

Ti doped hematite photoanodes have been intensively investigated due to their excellent activity for photoelectrochemical water oxidation. However, little attention has been paid to the doping effect on the photocurrent onset potential of hematite and the underlying mechanism. In this
paper, Ti doped hematite nanorod arrays were successfully prepared through a facile treatment of hematite with TiCl3 solution. The photocurrent of the Ti doped hematite photoanode increases by three times, and its onset potential shifts more positively as compared with that of the
undoped one. Electrochemical analyses were employed to unravel the mechanism of anodic shift of the onset potential. Cyclic voltammograms and electrochemical impedance spectra confirmed that more surface states were formed in Ti doped hematite than the undoped one. As a result, lower activity
towards oxygen evolution reaction (OER) and increased electron–hole recombination after light on/off in low potential region were observed in Ti doped hematite. It is concluded that these doping induced surface states may be a hindrance to charge transfer and the onset potential of Ti
doped hematite shifts anodically.

Water pollution induced by organic micropollutants (OMPs) poses a severe threat to human health and ecosystems. Catalytic membranes with photocatalysts immobilized either on the surface or within the bulk structure represent a promising strategy for OMPs degradation. However, the effective collision between OMPs and catalytically active sites is inherently limited, significantly reducing the degradation efficiency. To address this challenge, we fabricate a titanium (Ti)-organic hybrid nanofiltration membrane, in which Ti-oxygen clusters, acting as core photocatalytic sites, are bridged by rigid organic linkers to construct a nanoporous architecture. This design yields a photocatalytic membrane featuring fully exposed active sites within the open, accessible channels. As OMPs pass through the molecular-sized channels, each molecule is ensured to contact the catalytic sites, thereby boosting OMPs degradation. Taking tetracycline (TC) as a model OMP, this photocatalytic membrane achieves nearly 100% degradation at a high flux of 90 L m −2 h −1 , with a degradation rate as high a 9.9 × 10 −6 mol m −2 min −1 . This rate is one to three orders of magnitude higher than that of the photocatalytic membranes reported to date, and the membrane can simultaneously maintain stable operation for an extended period. This work establishes a new paradigm for the rational design of catalytic membranes.

Aluminum (Al), with its abundance and high energy release, has attracted great interest in nanocomposite energetic systems. However, the ignition temperature and combustion performance of Al-based thermites are limited by the oxide shell coating on the Al core. A novel metal carbodiimide oxidizer has been employed to assemble thermite with superior energy release in comparison with metal-oxide-based thermite. In this work, titanium (Ti) nanoparticles have been incorporated into the Al/CuNCN system with virous mass ratio (from 0 % to 100 %) to adjust their energetic behavior in comparison with traditional Al/CuO. The component, structure and morphology of the energetic composites were charactered by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectrophotometry (FT-IR). The temporal pressure traces and heat release of Al/Ti/CuNCN and Al/Ti/CuO composites have been measured via combustion cell and calorimetry, respectively. The over pressure of Al/30 %Ti/CuNCN reached to be 80 KPa, which is higher 9 KPa than the maximum pressure of Al/Ti/CuO. The energy release for both Al/Ti/CuNCN and Al/Ti/CuO proved to be lower than that of Al or Ti with oxides (CuO or CuNCN) owing to the alloying reaction. The high pressure of Al/Ti/CuNCN may offer the potential routes to prepare gas generators, and the results would be an essential guide in designing thermites. Besides, the metal nitrides such as AlN, TiN, Ti 9 N 3.87 were obtained in the aluminothermic reaction, providing new possible for the preparation of novel materials following a self-propagating route within one second.

LiAlH4, characterized by high hydrogen capacity and metastable properties, is regarded as a promising hydrogen source under mild conditions. However, its reversible regeneration from dehydrogenated production is hindered thermodynamically and kinetically. Herein, we demonstrate an active Li–Al–Ti nanocrystalline alloy prepared by melt spinning and cryomilling to enable directly synthesizing nano-LiAlH4. Due to the non-equilibrium preparation methods, the grain/particle size of the alloy was reduced, stress defects were introduced, and the dispersion of the Ti catalyst was promoted. The refined Li–Al–Ti nanocrystalline alloy with abundant defects and uniform catalytic sites demonstrated a high reactivity of the particle surface, thereby enhancing hydrogen absorption and desorption kinetics. Nano-LiAlH4was directly obtained by ball milling a 5% Ti containing Li–Al–Ti nanocrystalline alloy with a grain size of 17.4 nm and Al3Ti catalytic phase distributed under 20 bar hydrogen pressure for 16 h. The obtained LiAlH4exhibited room temperature dehydrogenation performance and good reversibility. This finding provides a potential strategy for the non-solvent synthesis and direct hydrogenation of metastable LiAlH4hydrogen storage materials.
