Advances in tissue engineering (TE) have revealed that porosity architectures, such as pore shape, pore size and pore interconnectivity are the key morphological properties of scaffolds. Well-ordered porous polymer scaffolds, which have uniform pore size, regular geometric shape, high porosity and good pore interconnectivity, facilitate the loading and distribution of active biomolecules, as well as cell adhesion, proliferation and migration. However, these are difficult to prepare by traditional methods and the existing well-ordered porous scaffold preparation methods require expensive experimental equipment or cumbersome preparation steps. Generally, droplet-based microfluidics, which generates and manipulates discrete droplets through immiscible multiphase flows inside microchannels, has emerged as a versatile tool for generation of well-ordered porous materials. This short review details this novel method and the latest developments in well-ordered porous scaffold preparation via microfluidic technology. The pore structure and properties of microfluidic scaffolds are discussed in depth, laying the foundation for further research and application in TE. Furthermore, we outline the bottlenecks and future developments in this particular field, and a brief outlook on the future development of microfluidic technique for scaffold fabrication is presented.

Covalent organic frameworks (COFs) with well-ordered nanopores and numerous accessible redox sites exhibit significant promise in aqueous zinc-ion batteries (AZIBs). However, challenges such as complex synthesis, limited capacity, and poor cycling stability still persist. In this study, we present a Zn preintercalation strategy enabling the one-pot synthesis of long-range interconnected COFs functionalized with -SO groups (COFs-Zn).

Carbon/transition metal oxide composites hold significant promise for energy storage applications; however, achieving precise control over the carbon structure to enhance the electrochemical activity of metal oxides remains a challenge. In this work, we utilized low-cost enzymatic lignin as a carbon source and harnessed the synergistic effects of magnesium oxide templates and potassium acetate activator to synthesize a lignin-derived hierarchical porous carbon (HPLC) characterized by a high specific surface area of 1704 ± 36 m/g, well-ordered nanosheet structures, and hierarchical porosity. The comparative analysis demonstrated that HPLC exhibited superior pore anchoring and enhanced interfacial Mn-O-C bonding interactions with manganese dioxide compared to mesoporous carbon synthesized via magnesium oxide templating and microporous carbon derived from potassium acetate activation.

Background: Bone defect regeneration is a dynamic healing process that relies on the body's innate repair mechanisms, yet natural healing capacity remains limited. To address this challenge, advanced biomaterials combining bioactive inorganic components with biocompatible polymers have emerged as a promising strategy to enhance osteogenesis and angiogenesis.
Methods: In this study, a novel three-dimensional composite scaffold material was successfully fabricated using a combined electrospinning-freeze drying technique.

Covalent organic frameworks (COFs) have emerged as promising electrode materials for sodium-ion batteries (SIBs) due to their well-ordered porous structures that facilitate ion storage and transport. However, conventional 2D and 3D COFs often require post-processing, such as ball milling or carbon compositing, to enhance electrochemical performance. In this study, a 1D imine-linked COF, N,N,N',N'-Tetrakis(4-aminophenyl)-1,4-phenylenediamine-2,6-pyridinedicarboxaldehyde (TP-PDA), is synthesized via a one-step Schiff base reaction, achieving a fully conjugated and porous structure that enables efficient sodium-ion transport.

This review explores the potential of biophotovoltaic devices (BPVs) as a sustainable solution for addressing the global energy crisis and combating climate change. BPVs generate renewable electricity from sunlight and water through the photosynthetic activity of microorganisms such as cyanobacteria and algae, which act as living photocatalysts. The study essentially focuses on improving photocurrent outputs through developing efficient anode materials.
