Significant advancements in research have been made in recent years, with single-junction organic solar cells achieving efficiencies exceeding 20%. However, scaling up laboratory prototypes to large-area commercial modules remains challenging due to the absence of high-quality thin-film deposition techniques, particularly for ultra-thin interfacial layers. In here, we demonstrate a fully vacuum-processed approach utilizing InCl3 as hole-contact and C60/BCP as electron-contact interlayers, respectively, which guarantees dense and uniform charge transporting layers, while also ensuring consistent batch-to-batch reproducibility of module performance. In addition, such ultra-thin InCl3 layer significantly reduces the surface free energy of ITO substrates, thereby inhibiting the coffee ring effect during the active layer deposition, and obtaining a more homogeneous film in a large-scale size. As a result, we measured a power conversion efficiency of 16.5% (certified efficiency: 15.8%) under 1-sun illumination for the best-performing organic solar modules (aperture area = 15.6 cm2) with a geometric fill factor of 95.5%, making them highly completive amongst recently reported modules at similar size. Most importantly, our vacuum-processed interlayers exhibit excellent reproducibility and scale-up ability, paving a way to accelerate the industrialization of organic photovoltaic technology.

Polycyclic aromatic hydrocarbons (PAHs) are a group of contaminants with low bioavailability and biodegradability . As a result, removing PAHs from contaminated soils is often inefficient. In this study, soils spiked with fluoranthene and pyrene were inoculated with Aeromonas sp. BCP-3, a newly isolated strain from coke-plant sludge , and treated in slurry bioreactors . The removal of PAHs was significantly affected by aeration rate, slurry water-soil mass ratio, stirring rate, temperature, and the concentration of Tween-80. Such effects were attributed to changes in BCP-3 growth, PAHs solid-liquid mass transfer, and slurry particle size. Notably, under optimal conditions (i.e., aeration rate of 1.5 L/min, temperature of 30 °C, stirring rate of 200 rpm, water-soil mass ratio of 1.5:1, and Tween-80 concentration of 1.3 %), 96.3 % and 97.2 % of initially spiked fluoranthene and pyrene were removed within 12 days, respectively. A PAH-contaminated soil was collected from a local coking plant and treated under the same conditions, except for the Tween-80 concentration. For the real soil, the Tween-80 concentration was 4 % to ensure a significant proportion of PAHs released into the liquid phase. Twenty-one days after inoculation of BCP-3, the removal efficiencies of low molecular weight PAHs and high molecular weight PAHs were 82.2 % and 51.8 %, respectively. The removal efficiencies of PAHs were significantly higher than the slurry without BCP-3 or HgCl 2 -sterilized slurry. BCP-3 improved the bioavailability and biodegradability of PAHs, resulting in effective PAH removal in slurry bioreactors . Overall, successful bioaugmentation was achieved with the addition of Tween-80 and the optimization of operating conditions.

PDMS-PU (polydimethylsiloxane-polyurethane) sponge decorated with In(OH)3 (indium hydroxide) and BCP (bromocresol purple) particles is shown to be a room-temperature ammonia sensor with high sensitivity and excellent reproducibility; it can accomplish real-time detection and monitoring of ammonia in the surrounding environment. The superhydrophobic and yellowish In(OH)3-BCP-TiO2-based ammonia-responsive (IBT-AR) sponge changes to a purple superhydrophilic one when exposed to ammonia. Notably, after reacting with ammonia, the sponge can recover its original wettability and color after heating in air. The wettability, color and absorption signal of IBT-AR sponge have been measured for sensing ammonia using the water contact angle, macroscopic observation and UV-vis absorption spectrometry, respectively. The minimum ammonia concentrations that can be detected by the sponge wettability, color and absorption signal are 0.5%, 1.4 ppm and 50 ppb, respectively. This kind of sponge with smart wettability and color is a promising new ammonia detector.

Large-scale bone defects resulting from trauma, infection, aging, tumors, and other diseases present significant clinical challenges. Current treatment modalities primarily involve surgical intervention, chemotherapy, and radiotherapy. However, conventional bone repair materials exhibit limitations in addressing tumor-associated defects, including inadequate drug loading capacity, uncontrolled release kinetics, and insufficient mechanical adaptability. To address these deficiencies in existing bone repair materials, we developed a novel composite bone scaffold utilizing a biphasic calcium phosphate (BCP) osteoconductive matrix. This matrix was integrated with polyacrylamide-modified gelatin (GelMA) hydrogel to enhance mechanical strength and oxidized sodium alginate (OSA) hydrogel containing pH-sensitive acylhydrazone bonds. The incorporation of the hydrogels significantly increased the compressive strength of the composite scaffold from 1.920 MPa to 2.515 MPa. Furthermore, the scaffold was physically adsorbed with the anti-tumor drug bortezomib (BTZ), demonstrating sustained release under simulated physiological conditions (pH 7.4). Notably, the release rate accelerated under acidic conditions that mimic the tumor microenvironment (pH 5.4 and 6.8).

Perovskite solar cells (PSCs) are considered the most promising photovoltaic devices to replace silicon-based solar cells because of their low preparation cost and high photoelectric conversion efficiency (PCE). Reducing defects in perovskite films is an effective means to improve the efficiency of PSCs. In this paper, a lead chelator was selected and mixed into hole transport layers (HTLs) to design and prepare mesoporous PSCs with the structure of ITO/PTAA(BCP)/Al2O3/PVK/PCBM/BCP/Ag, and its modification effect on the buried interface at the bottom of the perovskite layer in the mesoporous structure was explored. The experimental results show that in the presence of mesoporous alumina, the lead chelator can still play a role in modifying the bottom of the perovskite film. The use of lead chelator as passivation material added to the HTL can effectively reduce the residue of dimethyl sulfoxide (DMSO) and decrease the defects at the bottom of the perovskite film, which dramatically improves the device performance. The PCE of the device is increased from 18.03% to 20.78%, which is an increase of 15%. The work in this paper provides an effective method to enhance the performance of PSCs.

In this study, a conventional technique of porous preparation was used to improve the constructive capability of direct ink writing on microstructures, and the hierarchically porous scaffolds were successfully prepared by 3D gel printing (3DGP). Micron-sized hydroxyapatite (HA) was coated with tricalcium phosphate (TCP) nanopowders synthesized by chemical co-precipitation to form biphasic calcium phosphate (BCP). The random structure of concave micropores was achieved by filling the BCP slurry with PMMA microspheres while successfully controlling the internal porosity of printed filaments. The results showed that the three-stage porous structure was successfully constructed, i.e., macroscopic pores of 1.50–2.00 mm, spherical micropores of 100–200 µm, and inter-powder interstices of 1.00–10.00 µm. Nano-TCP coated micron-HA powders improved the sintering activity of BCP particles. The compressive strength and porosity of the scaffolds sintered at 1400 °C were 2.78 MPa and 84.98%. The hierarchically porous BCP scaffolds had bright applications in bone tissue engineering.

Hybrid heterostructure materials have received considerable attention due to the integration of each component and abundant functional applications in micromotors, catalysis, photothermal therapy, drug delivery, and bioimaging. However, the preparation of organic/inorganic heterostructure nanoparticles (HSNPs) with high quality still remains a remarkable challenge since thermodynamically metastable structures usually coexist, resulting in a lack of organic scaffolds with extreme uniformity both in shape and size distribution. Here, we prepared polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) block copolymer (BCP) core–shell spherical colloids driven by interfacial instability of soft and deformable emulsion droplets. Ultra-low interfacial tension was achieved through the co-adsorption of BCP segments and sodium dodecyl sulfate (SDS) surfactant, which had a strong affinity with the P4VP segment at the interface of the emulsified droplets. The excellent and homogeneous BCP colloids were further utilized as organic scaffolds to selectively grow a functional SiO2 layer on the surface of the BCP spherical colloids, producing BCP/SiO2 HSNPs with highly uniform shape and size distribution originating from the PS-b-P4VP scaffolds, thus providing an efficient and general strategy to construct and design organic/inorganic HSNPs with diverse applications.

Perovskite solar cells (PSCs) have attracted considerable research interest in recent decades due to their remarkable power conversion efficiencies. However, their thermal stability is remains one of the crucial challenges for commercial applications. Bathocuproine (BCP), widely employed as an interfacial buffer layer between the electron transport layer and the metal electrode, tends to undergo thermal aggregation at elevated temperatures, thereby compromising device stability. In this paper, the aggregation behavior of BCP under thermal stability test was investigated. It was proposed that introducing Polyethylenimine (PEIE) into BCP could inhibit its high-temperature aggregation. The -NH and -OH groups in PEIE can form hydrogen bonds with pyridine nitrogen in BCP. This interaction enables moderate π-π stacking between to exist within a wider temperature and improves the morphology and uniformity of the film. Concurrently, PEIE improves energy level alignment at the C60/BCP interface, facilitating more efficient electron extraction and transport. Moreover, the incorporation of PEIE remarkably suppresses the infiltration of Ag ions under continuous thermal conditions, which further boosts the thermal stability of the device. By utilizing the PEIE-modified BCP buffer layer, the resulting PSCs demonstrate a champion power conversion efficiency (PCE) of 25.83%. Even after 1000 hours operation under a relative humidity of 30%, it still maintains an efficiency of more than 85% demonstrating significantly enhanced stability. This work presents an innovative design strategy for developing PSCs with simultaneously enhanced efficiency and operational stability.

The repair of bone defects exceeding the natural regenerative capacity of bone remains a significant clinical challenge. Although various strategies have been explored, 3D-printed bioceramic scaffolds have emerged as a promising therapeutic solution. However, conventional bioceramics suitable for 3D printing often exhibit insufficient mechanical strength, limited antioxidant activity, and insufficient osteogenic activity. To overcome these limitations, three-dimensional (3D)-printed scaffolds were fabricated by incorporating cerium dioxide nanoparticles (CeO 2 NPs) into biphasic calcium phosphate (BCP) bioceramics containing 70 wt% hydroxyapatite (HA) and 30 wt% β-tricalcium phosphate (β-TCP). This composite approach aimed to enhance both antioxidant activity and osteogenic differentiation. The physicochemical properties, antioxidant capacity, in vitro cellular responses, and osteogenic potential of the scaffolds were systematically assessed. Results demonstrated that scaffolds containing 10 wt% CeO 2 NPs showed significantly improved mechanical and biological performance, particularly in antioxidant activity, compared to pure BCP scaffolds. Furthermore, a slight increase in microenvironmental pH induced by the BCP matrix may further enhance the antioxidant effects of CeO 2 NPs and promote osteogenesis. This study presents a BCP-CeO 2 composite scaffold with dual functions of antioxidant activity and osteogenic induction. It highlights that integrating CeO 2 NPs into BCP bioceramics via 3D printing technology holds promise for developing multifunctional scaffolds suitable for advanced bone tissue engineering applications.

Herein, we report a novel method to synthesize the dumbbell AuNRs@BCP nanoparticles via UV light-initiated RAFT polymerization-induced self-assembly in situ. This strategy provides a promising alternative for synthesizing asymmetric inorganic/polymeric hybrid nanoparticles with tunable morphologies. Shape-dependent surface-enhanced Raman scattering (SERS) experiments in dilute dispersions, along with electric field simulations, were conducted. Due to the plasmonic hotspots formed between the AuNRs and BCP domains, the dumbbell AuNRs@BCP nanoparticles were ideal for generating strong and reproducible SERS signals for methyl orange.

Incorporating a biomimetic coating and integrating osteoinductive biomolecules into basic bone substitutes are two common strategies to improve osteogenic capabilities in bone tissue engineering. Currently, the underlying mechanism of osteoporosis (OP)-related deficiency of osteogenesis remains unclear, and few treatments target at OP-related bone regeneration. Herein, we describe a self-assembling polyelectrolyte multilayered (PEM) film coating with local immobilisation of calcitriol (Cal) in biphasic calcium phosphate (BCP) scaffolds to promote osteoporotic bone regeneration by targeting the calcium sensing receptor (CaSR). Methods : The ovariectomy-induced functional changes in bone marrow mesenchymal stem cells (BMSCs), protective effects of Cal, and the potential mechanism were all verified. A PEM film composed of hyaluronic acid (HA) and chitosan (Chi) was prepared through layer-by-layer self-assembly. The morphology, growth behaviour, and drug retention capability of the composite scaffolds were characterised, and their biocompatibility and therapeutic efficacy for bone regeneration were systematically explored in vitro and in vivo. Results : The osteogenic differentiation, adhesion, and proliferation abilities of ovariectomised rat BMSCs (OVX-rBMSCs) decreased, in accordance with the deficiency of CaSR. Cal effectively activated osteogenesis in these OVX-rBMSCs by binding specifically to the active pocket of the CaSR structure, while the biomimetic PEM coating augmented OVX-rBMSCs proliferation and adhesion due to its porous surface structure. The PEM-coated scaffolds showed advantages in Cal loading and retention, especially at lower drug concentrations. HA/Chi PEM synergised with Cal to improve the proliferation, adhesion, and osteogenesis of OVX-rBMSCs and promote bone regeneration and BCP degradation in the critical-size calvarial bone defect model of OVX rats. Conclusion : A composite scaffold based on BCP, created by simply combining a biomimetic PEM coating and Cal immobilisation, could be clinically useful and has marked advantages as a targeted, off-the-shelf, cell-free treatment option for osteoporotic bone regeneration.

Digital light processing (DLP)-based 3D printing is suitable to fabricate bone scaffolds with small size and high precision. However, the published literature mainly deals with the fabrication procedure and parameters of DLP printed bioceramic scaffold, but lacks the subsequent systematic biological evaluations for bone regeneration application. In this work, a biphasic calcium phosphate (BCP) macroporous scaffold was constructed by DLP-based 3D printing technique. Furthermore, bone morphogenetic protein-2 (BMP-2) was facilely incorporated into this scaffold through a facile polydopamine (PDA) modification process. The resultant scaffold presents an interconnected porous structure with pore size of ∼570 μm, compressive strength (∼3.6 MPa), and the self-assembly Ca-P/PDA nanocoating exhibited excellent sustained-release property for BMP-2. Notably, this BMP-2/PDA-BCP scaffold presents favorable effects on the adhesion, proliferation, osteogenic differentiation, and mineralization of bone marrow stromal cells (BMSCs). Furthermore, in vivo experiments conducted on rats demonstrated that the scaffolds could induce cell layer aggregation adjacent to the scaffolds and continuous new bone generation within the scaffold. Collectively, this work demonstrated that the BMP-2/PDA-BCP scaffold is of immense potential to treat small craniofacial bone defects in demand of high accuracy.
