“…reported a novel composite material by coating β‐sheet SAPH FEFEFKFK on 3D‐printed PCL scaffolds, which exhibited excellent effect in repairing osteochondral defects derived from OA or acute trauma. [ 22 ] As shown in Figure a, PCL granules were first melted at 120 °C and then printed by 3D bio‐printer. In the next step, strong hydrophobic interactions are formed between PCL and β‐sheet SAPH, allowing the SAPH FEFEFKFK to be stably deposited on the surface of PCL porous scaffolds.…”

Bone related diseases have caused serious threats to human health owing to their complexity and specificity. Fortunately, owing to the unique 3D network structure with high aqueous content and functional properties, emerging hydrogels are regarded as one of the most promising candidates for bone tissue engineering, such as repairing cartilage injury, skull defect, and arthritis. Herein, various design strategies and synthesis methods (e.g., 3D‐printing technology and nanoparticle composite strategy) are introduced to prepare implanted hydrogel scaffolds with tunable mechanical strength, favorable biocompatibility, and excellent bioactivity for applying in bone regeneration. Injectable hydrogels based on biocompatible materials (e.g., collagen, hyaluronic acid, chitosan, polyethylene glycol, etc.) possess many advantages in minimally invasive surgery, including adjustable physicochemical properties, filling irregular shapes of defect sites, and on‐demand release drugs or growth factors in response to different stimuli (e.g., pH, temperature, redox, enzyme, light, magnetic, etc.). In addition, drug delivery systems based on micro/nanogels are discussed, and its numerous promising designs used in the application of bone diseases (e.g., rheumatoid arthritis, osteoarthritis, cartilage defect) are also briefed in this review. Particularly, several key factors of hydrogel scaffolds (e.g., mechanical property, pore size, and release behavior of active factors) that can induce bone tissue regeneration are also summarized in this review. It is anticipated that advanced approaches and innovative ideas of bioactive hydrogels will be exploited in the clinical field and increase the life quality of patients with the bone injury.

“…The most common one is based on a conventional regular structure (TCO/ETL/perovskite/gold or carbon) ( Table 2 ). [ 25,48,86,87,89–103 ] This type was first designed by Etgar and co‐workers in 2012. The other type is the printable mesoscopic structure (TCO/ETL/ZrO 2 insulated layer/carbon: perovskite) ( Table 3 ).…”

Perovskite solar cells (PSCs) are considered one of the most promising nextgeneration examples of high-tech photovoltaic energy converters, as they possess an unprecedented power conversion efficiency with low cost. A typical high-performance PSC generally contains a perovskite active layer sandwiched between an electron-transport layer (ETL) and a hole-transport layer (HTL). The ETL and HTL contribute to the charge extraction in the PSC. However, these additional two layers complicate the manufacturing process and raise the cost. To extend this technology for commercialization, it is highly desired that the structure of PSCs is further simplified without sacrificing their photovoltaic performances. Thus, ETL-free or/and HTL-free PSCs are developed and attract more and more interest. Herein, the commonly used methods in reducing the defect density and optimizing the energy levels in conventional PSCs in order to simplify their structures are summarized. Then, the development of diverse ETL-free or/and HTL-free PSCs is discussed, with the PSCs classified, including their working principles, implemented technologies, remaining challenges, and future perspectives. The aim is to redirect the way toward low-cost and high-performance PSCs with the simplest possible architecture.

“…Heterostructures have been widely applied in fields of electronics, thermoelectrics, optoelectronics, and field‐emission devices because they generally exhibit favorable properties such as high electron mobility, good emission efficiency, and high charge spatial separation ability. [ 1–8 ] Recently, some heterostructures emerged as a new class of electrode materials for Na‐ion storage, such as CoO/Co 3 S 4 , [ 9 ] SnS/SnO 2 , [ 10 ] and Co 9 S 8 /ZnS.

Heterostructures are attracting increasing attention in the field of sodium‐ion batteries. However, it is still unclear whether any two monophase components can be used to construct a high‐performance heterostructure for sodium‐ion batteries, as well as the kind of heterostructures that can boost electrochemical performances. In this study, based on classical semiconductor theories on antiblocking and blocking interfaces, attempts are made to answer the abovementioned queries. For this purpose, NiTe2–ZnTe antiblocking and CoTe2–ZnTe blocking heterostructures are synthesized through a bimetal‐hexamine framework‐derived strategy. The NiTe2–ZnTe antiblocking heterostructure exhibits excellent high‐rate and cycling performances, while the CoTe2–ZnTe blocking heterostructure performs poorly, even compared to their monophase components. Further, kinetic measurements and theoretical calculation confirm that antiblocking heterointerfaces can boost Na‐ion diffusion efficiency and decrease the diffusion barrier, which can be attributed to the highly conductive antiblocking heterointerfaces generated due to electron transfer from NiTe2 to ZnTe. Therefore, this study provides a new perspective to design heterostructures more efficiently, with significantly better Na‐ion storage performance.
