The integration of heterogeneous photocatalysts has emerged as a promising approach to boost the effectiveness of photocatalytic reactions for hydrogen evolution. In this study, we explore the synergistic effects of Ti 3+ -TiO 2 /P-doped g-C 3 N 4 heterojunctions on the enhancement of visible light-induced hydrogen generation efficiency. The photocatalytic hydrogen evolution performance of the as-prepared TPCN100 (280.38 μmol g −1 h −1 ) surpasses that of pristine P-doped g-C 3 N 4 (34.89 μmol g −1 h −1 ) and Ti 3+ -TiO 2 (39.71 μmol g −1 h −1 ) by factors of 8.0 and 7.1 respectively. Through a comprehensive investigation of the structural, electronic, and photocatalytic properties, the underlying mechanisms accountable for the observed enhancement in efficiency within the heterojunction system were elucidated. Based on the in-situ X-ray photoelectron spectrometer (XPS) examination, measurement of band edge, and electron paramagnetic resonance (EPR) analysis, the S-scheme photocatalytic mechanism was proposed. The integration of Ti 3+ -TiO 2 and P-doped g-C 3 N 4 offers new insights into the design of advanced photocatalytic materials for sustainable energy applications.

Fast, sensitive, and simple methods for quantitative analysis of disparities in glycan expression between different biological samples are essential for studies of protein glycosylation patterns (glycomics) and the search for disease glycan biomarkers. Relative quantitation of glycans based on stable isotope labeling combined with mass spectrometric detection represents an emerging and promising technique. However, this technique is undermined by the complexity of mass spectra of isotope-labeled glycans caused by the presence of multiple metal ion adduct signals, which result in a decrease of detection sensitivity and an increase of difficulties in data interpretation. Herein we report a simplified quantitative glycomics strategy, which features nonreductive isotopic labeling of reducing glycans with either nondeuterated (d0-) or deuterated (d5-) Girard’s reagent P (GP) without salts introduced and simplified mass spectrometric profiles of d0- and d5-GP derivatives of neutral glycans as molecular ions without complex metal ion adducts, allowing rapid and sensitive quantitative comparison between different glycan samples. We have obtained optimized GP-labeling conditions and good quantitation linearity, reproducibility, and accuracy of data by the method. Its excellent applicability was validated by comparatively quantitative analysis of the neutral N-glycans released from bovine and porcine immunoglobulin G as well as of those from mouse and rat sera. Additionally, we have revealed the potential of this strategy for the high-sensitivity analysis of sialylated glycans as GP derivatives, which involves neutralization of the carboxyl group of sialic acid by chemical derivatization.

Controlling the morphology of metal–organic frameworks (MOFs) is critical for tailoring their transformation into metal oxides with unique microstructures and properties, particularly for gas sensing applications. In this study, a dual In-MOF-MF was developed using a mixed linker approach involving terephthalic acid and fumaric acid. These two linkers interact with In 3 + ions to produce nanofibers with a high aspect ratio. The resulting In 2 O 3 -MF exhibits superior acetone sensing properties compared to In 2 O 3 derived from single-linker MOFs. Furthermore, the n-type In 2 O 3 -MF was coupled with p-type PtO to create a p-n junction gas sensor. The combination of rich active sites and the well-defined coupling interfaces between PtO and In 2 O 3 -MF leads to remarkable acetone sensing performance, featuring a high response (347–100 ppm acetone), rapid response/recovery time (34/18 s), excellent selectivity, and a relatively low detection limit (300 ppb). This work highlights a mixed-linker strategy for MOF morphology manipulation, enabling the fabrication of a one-dimensional p-n junction for next-generation advanced acetone sensing applications.

In this study, we present a simple oxide assisted p-type doping of Si nanostructures by evaporating a mixed powder composed of SiB6 and SiO. It was found that Si nanoribbons (Si NRs) which can be obtained at high SiB6 content, will give way to Si nanowires (Si NWs) when the content of SiB6 in the mixed powder was reduced. According to our transport measurement of field effect transistors (FETs) assembled on individual Si nanostructures, the as-prepared Si nanostructures with different boron doping levels all exhibit typical p-type conduction characteristics. Additionally, the electrical conductivity of the Si nanostructures can be tuned over 7 orders of magnitude from 8.98 × 102 S cm−1 for the highly doped sample to 3.36 × 10−5 S cm−1 for the lightly doped sample. We also assembled a nano-photodetector based on monolayer graphene and the as-prepared Si nanostructures, which exhibits ultra-sensitivity to 850 nm near infrared light (NIR) illumination with a nanosecond response speed (τrise/τfall: 181/233 ns). The generality of the above results suggest that the Si nanostructures are promising building blocks for future electronic and optoelectronic device applications.

High-performance p-type atomically thin transistors are fundamental components in CMOS-based digital logic circuits for beyond-silicon electronics. Compared with the recent breakthrough in high-quality semimetal contacts approaching the quantum limit on n-type atomically thin channel transistors, achieving high-performance p-type analogues with high-quality contacts remains challenging, which was mainly hindered by the lack of proper high-work-function metallic electrodes with Fermi level unpinning capacity. Herein, we demonstrate that semimetal TiS2 electrodes prepared with a damage-free transfer process can be a feasible option for p-type atomically thin MoTe2 transistors. Owing to its intrinsic large work function (∼5.3 eV) and high-quality contacts with negligible Schottky barrier at the TiS2/MoTe2 interface, the scaled p-type bilayer MoTe2 transistor with 500 nm channel length and the monolayer transistor with 800 nm channel length exhibit a high on-state current (Ion) of 100 μA/μm with the on/off ratio (Ion/off) over 106 and an Ion of 68 μA/μm with the Ion/off ratio over 107, respectively. Such a demonstration will enable monolithic atomically thin MoTe2-based beyond-silicon electronics via the common CMOS technology.

Potential of zero free charge (PZFCs) of Pt(111)/0.1 M HClO 4 interface with adsorbed P-block elements X ad ( X = I, Br, Te, Se and S) of various coverages are investigated using electrochemical reduction of peroxodisulfate (PDS) as the probe reaction, aiming at understanding the mechanism of adatom in regulating the PZFCs of Pt(111)@X ad /0.1 M HClO 4 interface. Experimental observations reveal that increase adatom coverage on Pt(111) results in a monotonic positive shift in the PZFCs with S, Se and Br adatoms. The maximum PZFCs with saturated S ad , Se ad and Br ad are in the range of ca. 0.5–0.53 V RHE , which is positively shifted by ca. 0.14–0.17 V comparing to the PZFC of unmodified Pt(111)/0.1 M HClO 4 interface. In contrast, whereas I and Te adatoms lead to a nonmonotonic change of PZFCs with coverage, characterized by an initial positive shift up to ca. 0.51/0.48 V RHE followed by a sharp drop down to ca. 0.17/0.14 V RHE at higher coverages. The origin for such phenomenon can be well rationalized by the displacement of adsorbed water on Pt(111) by X ad , such displacement induced change of electron spillover from the Pt surface as well as the electronic effect of X ad and Pt.

Extraction of native-like lignin from lignocellulose is crucial for maximizing the value of all three major components of biomass. In this study, molecular dynamics was employed to reveal the essence of lignin condensation during the pretreatment of biomass with a promising acidic hydrotropic solution (AHS) at the molecular level. Diols were discovered to effectively suppress the excessive acidity of p-toluenesulfonic acid (pTsOH) in AHS while maintaining its solubilizing effect below a minimal hydrotropic concentration (MHC). The experimental results confirmed that the combined use of 1,4-butanediol and pTsOH can extract native-like lignin under mild conditions. The retention of lignin's β-O-4 linkages can exceed 90%, and the lignin extraction rate was over 80%. The obtained lignin can enhance the efficacy of chemical sunscreens, doubling the sun protection factor (SPF). Simultaneously, the residual cellulose was readily hydrolyzed into glucose by cellulase. This strategy demonstrates excellent adaptability to various biomass sources, including herbaceous species, hardwoods, and highly recalcitrant softwoods. The work lays the theoretical foundation for the precise control of biomass component separation using AHS, contributing to the development of mild and efficient component separation technologies in the future.

Hydrogen energy as a new type of clean energy has been widely used. Electrolysis is a highly effective method of producing hydrogen from water. Catalysts with low development costs and high efficiency are the focus of current research. A novel Ni–W–P/Mo catalyst for hydrogen evolution reaction (HER) was synthesized by electrodeposition based on a molybdenum mesh. The experimental results show that when the current density is 10 mA/cm2, the best overpotential of Ni–W–P/Mo in alkaline medium is 75 mV. Not only that, the Tafel slope (77 mV/dec) also proves its excellent dynamic performance. In addition, the 60 h stability test at a current density of 10 mA/cm2 indicates an excellent long-term stability performance. Compared with the catalysts reported in recent years, the HER performance of Ni–W–P/Mo is much better than that of most nonprecious metal catalysts. The uniform and regular molybdenum network provides a large area of support for the catalyst, which is conducive to the synthesis and reaction of the catalyst. By doping W, the electronic structure of the catalyst is regulated, and the water decomposition is promoted. The stability of the morphology is also an important factor in improving the activity of the catalyst. The amorphous catalyst synthesized by the electrodeposition method in this work provides a new idea for the research of catalytic materials for hydrogen production by electrolysis of water and has important significance for promoting the development of a hydrogen energy economy.

In micro-injection molding, polymer/mold interface adhesion may cause severe deformation or damage of micro features on the molded products. To reduce the interface adhesion and improve the molding quality of polymer microfluidic chip, Ni-P-PTFE (polytetrafluoroethylene) ternary composite was adopted to electroform mold insert with self-lubricating properties. The influence of phosphorous acid concentration on the composition and performance of Ni-P-PTFE composites was systematically investigated. Our results demonstrated that the content of P and PTFE particles in the composites raised with an increase in phosphorous acid concentration. Elevated phosphorous acid concentration adversely affected the current efficiency and slowed down the deposition rate, allowing sufficient contact time for PTFE to transfer and adsorb onto the electrode surface. The hardness of the deposited nickel increased from 310 HV to 510 HV in the Ni-P-PTFE composites. Furthermore, the Ni-P-PTFE composites demonstrated excellent self-lubricating properties, showcasing friction coefficients of 0.15 and 0.25 during the initial and steady stages, respectively, representing a notable reduction of 66.7 % and 64.3 % compared to pure nickel. This study provides a novel approach to fabricate molds with self-lubricating properties, which contributes to the high-precision injection molding of polymer-based micro devices.

Efficient removal of p -arsanilic acid ( p -ASA) from contaminated water is crucial for mitigating arsenic contamination. In this study, a membrane adsorbent named CFM-Zn is developed by retanning Zn on a collagen fiber membrane (CFM). This development leverages the unique physicochemical properties of CFM and the strong affinity of Zn for p -ASA. The membrane is composed entirely of green, low-carbon, and recyclable materials, achieving sustainable removal of p -ASA and embodying the concept of using waste to treat waste for environmental recovery. Remarkably, it exhibits an ultra-high capacity of up to 515.46 mg·g −1 . Additionally, CFM-Zn demonstrates moderate reusability, with effectiveness maintained for at least five cycles. This study could advance the development of bio-based materials for water pollutant removal, expand the applications of leather waste, and significantly promote environmental purification and resource recycling.

Ternary Ni-Co-P/TiN (20 nm) nanocomposite coatings with Co content in the range of 0–23 wt% were successfully co-deposited on Al alloys by electroless plating. The morphology, composition, microstructure, micro-hardness, wear behavior, and corrosion properties of the coatings were tested using SEM, EDS, XRD, Vickers hardness, ball-on-disc wear tester, and electrochemical workstation, respectively. The effect of Co content on the tribological and corrosion properties of Ni-Co-P/TiN coatings was studied. It is found that all the coatings have a compact and rough granular structure with sub-micro globules non-uniformly distributed on the surface. The grain size and the content of Ni and P decrease, but the micro-hardness, adhesion force, friction coefficient, and corrosion resistance correspondingly enhance with the increase of Co content in Ni-Co-P/TiN coatings. The improved corrosion resistance of Ni-Co-P/TiN coating is due to the passivation behavior and small grain caused by the introduction of Co. Based on the excellent properties on the wear and corrosion resistance, ternary Ni-Co23-P/TiN coating with high Co content, may be applied as an optimum protective coating for Al alloys.

As a common animal feed additive, p-arsanilic acid (p-AsA) is thought to be excreted with little uptake and unchanged chemical structure, threatening the environment by potentially releasing more toxic inorganic arsenic. We herein investigated the removal of arsenic by in situ formed ferric (oxyhydr)oxides with the promotion of p-AsA degradation in Fe(II)/peroxydisulfate (PDS) system. Results showed that under acid conditions, p-AsA degraded very quickly and over 99% of p-AsA (5 μM) was degraded within 10 min at the optimal dosage of Fe(II) (100 μM) and PDS (150 μM) at pH 3, while less than 66.4% of arsenic was removed at pH 3–5. Higher pH (3–7) would inhibit the degradation of p-AsA but promote the arsenic removal. At pH 6–7, over 98.5% of total arsenic was removed, while the degradation efficiency of p-AsA was lower than 52.4%. HPLC-ICP-MS results indicated that the arsenic group was cleaved from p-AsA in the form of As(III) and then rapidly oxidized to As(V). FTIR and XPS analysis indicated that both As(V) products and residual p-AsA were bonded to ferric (oxyhydr)oxides via hydroxyl groups. Common cations (e.g., Na + , Ca 2+ , Mg 2+ ) and anions such as Cl − , SO 4 2− , CO 3 2− had no significant influence on arsenic removal, while SiO 3 2− , PO 4 3− and HA inhibited the removal of total arsenic, mainly by affecting the zeta potential of iron particles. In summary, the Fe(II)/PDS process, as an efficient method for partial oxidation and simultaneous adsorption of p-AsA under near-neutral conditions, is expected to control the potential environmental risks of p-AsA.
