Enhanced photocatalytic performance and excellent stability are usually regarded contradictory during photocatalytic reaction. In this study, supercycle ALD was employed to achieve superior performance and stability simultaneously for the system of TiO 2 @Cu during CO 2 reduction reaction, which was unattainable by post-deposition TiO 2 , a commonly-employed technique for enhancing stability. More oxygen vacancy, partially-covered Cu species as well as well-maintained charge separation capability of alternatively-deposited TiO 2 @(2Cu + 2TiO 2 ) × 25 could be the reason for enhanced activity and stability as suggested by a series of characterizations such as Single-particle TRPL and Single-particle PL. Experimental data also suggested unselective and mixed-layer deposition of TiO 2 and Cu loaded in the mode of alternative-deposition. The method proved in our study could be applicable in synthesizing other ALD-prepared catalysts with enhanced performance and stability, which will be a big step forward towards comprehensively utilizing the potential of ALD technique in the field of photocatalysis.

Due to the high conformal films, atomic layer deposition (ALD) alumina has been used as a uniform stationary phase or support layer of stationary phase for micro gas chromatographic column. However, the severe tailing of chromatographic peaks appears when ALD alumina is used as the stationary phase. Recently, an H-diffusion model was proposed to explain the H accumulation phenomenon of ALD alumina films. Compared with the normal-resistance silicon substrates, the ALD alumina films based on low-resistance silicon substrates have fewer H impurities, which may further improve the tailing of chromatographic peaks and the theoretical number of plates. In this paper, a micro gas chromatographic column based on the low-resistance silicon (LR-μGCC) substrate (resistivity, 0.001–0.005 Ω·cm) using alumina deposited by atomic layer deposition as the stationary phase is reported. Compared with normal-resistance silicon substrates (resistivity, 1–10 Ω·cm), the micro gas chromatographic columns (μGCC) prepared on low-resistance silicon substrates have a higher separation performance. The test results showed that the LR-μGCC increased the theoretical plate number of alkane mixtures (n-hexane, n-octane, n-nonane, and n-decane) by 20.9%, 74.8%, 139.4%, and 55.4%, respectively, and reduced the tailing factor by 13.0%, 41.8%, 48.6%, and 49.1%, respectively.

Transition metal nitrides have good metallic conductivity and high pseudocapacitance, which have drawn extensive attention in the research of Zn-ion energy storage systems. In this paper, we present a novel fabrication of carbon cloth-supported TiN-coated carbon nanotube composites (TiN/CNTs@CC and TWC) via a CVD–ALD method using ethanol, TiCl4 and H2O as precursors. The prepared TWC composites can be used as self-supported electrodes with good flexibility and conductivity. Electrochemical performance tests show that the TiN/CNTs@CC electrode has a high specific capacitance of 363.5 F g−1 at 0.5 A g−1, good rate capability and excellent cycling stability with 92.9% capacity retention over 10 000 charge/discharge cycles. Impressively, the assembled zinc ion hybrid capacitor can achieve a high energy density of up to 81.8 W h kg−1 at a power density of 137.7 W kg−1. Even at a power density of 3013.7 W kg−1, a high energy density of 26.4 W h kg−1 is still achieved. This study provides a new insight into the application of nitride-derived carbon materials in zinc-ion hybrid capacitors.

Drug tolerance is clinically common but its mechanism is unclear. Previous studies found RSV tolerance in ALD treatment. This study explores mechanisms involving gut bacteria and host factors. Male C57BL/6J mice were induced into ALD with the Lieber-DeCarli alcohol diet, then ALD-RSV group mice were gavaged RSV (150 mg/kg/day) for 5 weeks. Throughout the experiment, ALD and ALD-RSV mice were on the Lieber-DeCarli alcohol diet, while the Vehicle group received a control diet. By week 5, tolerance to RSV efficacy emerged, with markedly reduced RSV exposure at the final dose. ALD-RSV group exhibited increased levels of Eggerthella lenta ( E.lent ), which metabolizes RSV into dihydroresveratrol (DHR). Chronic RSV treatment upregulated UGT1A1, the enzyme converting RSV into its primary metabolite, trans-resveratrol-3-O-β-D-glucuronide (R3G). The synergy between gut bacteria and host factors enhances RSV metabolism in ALD mice, driving tolerance and offering insights into other clinical drugs tolerance mechanisms.

To produce cotton fabrics with infrared-insulating properties, TiO 2 nanoparticles are uniformly and firmly coated onto the fabric using low-temperature atomic layer deposition (ALD) technology at 90 °C. Cotton fabric samples were tested and the experimental data indicated that the fabrics treated by the ALD process had excellent infrared resistance and reflection properties, with the infrared and thermal insulation rates of 67.6 and 28.5% increasing to 86.7 and 63.9%, respectively, after 2000 ALD cycles. The thickness of the fabric increased with the number of ALD cycles, as determined using a fabric thickness gauge. The fabric surface morphology and fibre cross-sections were examined using a scanning electron microscope and transmission electron microscope, respectively. Energy-dispersive X-ray spectroscopy was used to confirm that TiO 2 was the main component of the coating on the surface of cotton fabric. Beyond that, an infrared camera was used to detect the temperature of the upper and lower surfaces of the fabric and a thermal gravimetric analyser was used to show how the TiO 2 particles were deposited on the cotton fabric.

The Ni-rich LiNixCoyMn1−x−yO2 cathode (x ≥ 0.6) shows weak rate capability due to its deleterious surface lithium impurities and lattice defects. Herein, uniform ultrathin B2O3 coatings built by atomic layer deposition (ALD) are utilized to construct a B3+ doped single-crystal LiNi0.83Co0.12Mn0.05O2 (SC83) via post-annealing. LiOH is consumed due to reacting with B2O3 during the B2O3 ALD process, and then B2O3 is transformed into B3+ doping accompanied by the reduction of Li2CO3 during the post-annealing. Surface and bulk characterization results show that B3+ tends to diffuse into the bulk of the SC83 during the post-annealing, which expands the a and c axes and reduces the Li+/Ni2+ mixing of the SC83. When the B3+ content exceeds 0.54 wt%, B3+ segregation occurs on the surface of the SC83, which decreases the electronic conductivity of the SC83. B3+ doping at the content of 0.54 wt% gives the highest capacity of 177.6 mA h g−1 at 1C rate. The B2O3 ALD coupled with post-annealing builds a highly electronic and Li+ conductive surface and bulk for the SC83, which is the key to the improvement of the rate capability.

Alcoholic liver disease (ALD) is a primary cause of mortality and morbidity worldwide. Oxidative stress and inflammation are important pathogenic factors contributing to ALD. We investigated the protective mechanism of galacto-oligosaccharide (GOS) against ALD through their antioxidant and anti-inflammatory activities by performing in vivo and in vitro experiments. Western blot and RT‒PCR results indicated that the expression of cytochrome P450 protein 2E1 (CYP2E1) in liver tissues and L02 cells was reduced in the GOS-treated mice compared with the model group. In addition, GOS prominently reduced the expression of Kelch-like ECH-associated protein 1 (Keap1), increased the expression of the nuclear factor erythroid-2-related factor 2 (Nrf2) and haem oxygenase-1 (HO-1) proteins, and enhanced the antioxidant capacity. In addition, GOS decreased inflammation by reducing inflammatory factor levels and inhibiting the mitogen-activated protein kinase (MAPK)/nuclear factor kappa B (NF-κB) pathway. Based on these results, GOS may be a prospective functional food for the prevention and treatment of ALD.Keywords:alcoholic liver disease (ALD);antioxidant;anti-inflammatory;galacto-oligosaccharide;hepatoprotective

Carotid-artery atherosclerosis is a common cause of ischemic stroke. Carotid-artery stenting (CAS) is one of the most effective treatments. However, In-stent restenosis (ISR) and re-endothelialization delay are two major issues of intravascular stent which affect clinical safety and reduce effects. In this study, atomic layer deposition (ALD) technology was applied to deposit a layer (10 nm) of Al 2 O 3 on Nitinol surface as an intermediate functional layer. The alumina covered surface was then modified with a coupling agent 3-aminopropyltriethoxysilane (APS) and heparin sequentially in order to improve the hemocompatibility of Nitinol stents. The successful graft of APS and heparin onto Nitinol was proven by X-ray photoelectron spectroscopy. Furthermore, the predicted improvement in the biocompatibilities of modified Nitinol was confirmed by water contact angle measurement, protein adsorption, platelet adhesion, and plasma recalcification time determination. The results of hemolysis assay, cell proliferation and cytotoxicity tests revealed that the grafting of heparin on NiTi kept the original positive performance of nitinol material. The results indicate that ALD technology is of great potential for the manufacture of medical devices, especially for surface modifications and functionalization. ALD technology can help with modifications of inert metallic surfaces and therefore benefit implantable medical devices, especially intravascular stents.

As a cost-effective material, CuO has been widely used in many emerging fields. The synthesis method plays a key role in the performance of the material. Atomic layer deposition (ALD) has been developed as a precise technique to deposit materials with great control at atomic scale. Herein, an efficient process of ALD CuO is reported by using [Cu( s Bu-amd)] 2 and O 3 as precursors. CuO films can be deposited on SiO 2 substrates with typical self-limiting growth behaviors at 120–220°C. Notably, the growth rate of the CuO films is reach up to 2.5 Å/cycle, which is 6~12 times more than the available value. This remarkably high efficiency is the critical factor to promote the large-scale applications of ALD CuO materials. Furthermore, CuO is deposited on TiO 2 nano-particles (forming CuO/TiO 2 composite) using this ALD process to evaluate its performance for H 2 evolution. The 0.37 wt % CuO/TiO 2 composite (120 cycles CuO/TiO 2 ) can achieve a H 2 evolution rate of 3995 μmol g –1 h –1 , which is nearly 200 times larger than pure TiO 2 .

In this work, the atomic layer deposition-zinc oxide (ALD-ZnO) modified membrane was fabricated and the effects of ionic strength, co-existing Ca 2+ and Mg 2+ on its fouling potential were systematically investigated. Results showed excellent anti-irreversible fouling performance of PVDF-ZnO modified membrane with co-existing cations. Attractively, the values of declined membrane flux dropped by 25.7%, 25.9% and 22.3% after ZnO modification in the presence of 50 mM NaCl, 1.0 mM Ca 2+ and 1.0 mM Mg 2+ , respectively. Besides, Ca 2+ was prone to cause membrane fouling than Mg 2+ . Furthermore, fitting of multistage filtration models revealed that membrane fouling was ascribed to dynamic adsorption initially, followed by surface and pores deposition when filtrating BSA with or without Mg 2+ . However, the modified membrane experienced reverse process with higher ionic strength or Ca 2+ addition due to BSA molecular cluster. Moreover, the reduced repulsive energy induced by charge screening and calcium bridging resulted in slight aggravation of membrane fouling. Interestingly, the flux of PVDF-ZnO fouled membrane was easily recovered after physical cleaning. These findings provided deep insight into practical application of ALD modified membrane in wastewater remediation.

Rechargeable alkali metal-chlorine batteries are emerging as a promising high-energy-density solution. However, they confront significant challenges, including the primary issue stemming from the weak binding affinity of cathode materials for Cl 2 , which leads to a sluggish and inadequate supply of Cl 2 during the redox reactions, resulting in a shortened cycle life and low Coulombic efficiency (CE), particularly when operating at ultrahigh specific capacity outputs. Herein, an Al 2 O 3 -skinned heterostructured starburst porous graphene with conformal metasurfaces (Al 2 O 3 @rGO) is reported, crafted from a hierarchical porous starburst graphene arranged in a unique layered structure by the PTFE microemulsion skin effect, leveraging subsequent fluidized bed atomic layer deposition (FBALD) of Al 2 O 3 groups. Al 2 O 3 @rGO features superhydrophilicity, effective adsorption, fast kinetics from stable dynamic respiratory interface, high electrical and thermal conductivity anisotropy, intelligent thermal management and safe operation over a wide temperature range. Consequently, the Li-Cl 2 @Al 2 O 3 @rGO battery achieves an ultrahigh discharge specific capacity of 5000 mAh g −1 at ≈100% CE, and even delivers stable cycling over 200 cycles with 2000 mAh g −1 at an average CE of 99.8% under low temperature environment of -40 °C. The scalable heterostructure approach offers a sustainable perspective of the development of functionalized metamaterials and metasurfaces for next-generation safe and energy-dense batteries and broader applications.

Atomic layer deposition (ALD) technique has been proved to be an efficient method to synthesize or modify catalyst. In this study, Cu was loaded on different TiO 2 substrates, pristine TiO 2 and black TiO 2 (denoted as H-TiO 2 ) to achieve better CO 2 photocatalytic reduction performance. Both TiO 2 @Cu and H-TiO 2 @Cu exhibited dramatic enhancement for CO and CH 4 production. The peculiar phenomenon of TiO 2 outperforming H-TiO 2 after ALD loading was further studied by a series of characterization methods. Even though H-TiO 2 showed superior performance for photocatalytic CO 2 reduction than TiO 2 , pristine TiO 2 loaded with more Cu 0/+ after ALD deposition surpassed the performance of H-TiO 2 @Cu which possessed less amount of Cu 0/+ and more Cu 2+ . Cu 0/+ is proved to be the crucial factor for CO 2 reduction and it is capable of overshadowing the influence of Ti 3+ and V o . These results indicate that not only will ALD technique significantly enhance the CO 2 reduction performance after Cu deposition, but the substrate employed for loading and the chemical state of loaded material will also influence the subsequent catalytic performance. In addition, our result provides additional experiment evidence for justifying the significance of Cu 0/+ in photocatalytic CO 2 reduction reaction.
