Abstract The shapes of micro‐ and nano‐products have profound influences on their functional performances, which has not received sufficient attention during the past several decades. Electrohydrodynamic atomization (EHDA) techniques, mainly include electrospinning electrospraying, are facile in manipulate products' shapes. In this review, generated using EHDA for modifying drug release profiles reviewed. These linear nanofibers, round micro‐/nano‐particles, beads‐on‐a‐string hybrids. They can be further divided into different kinds sub‐shapes, explored providing desired pulsatile release, sustained biphasic delayed pH‐sensitive release. Additionally, resulted from organizations electrospun nanofibers discussed delivery, inner structures considered together developing novel delivery systems. future, related shape–performance relationships at nanoscale, besides size, structure structure–performance relationships, would play important roles promoting developments field.

Combination therapy with oral administration of several active ingredients is a popular clinical treatment for cancer. However, the traditional method has poor convenience, less safety, and low efficiency patients. The combination pharmaceutical techniques advanced material conversion methods can provide new solutions to this issue. In research, kind hybrid film was created via coaxial electrospraying, followed by casting process. films were composed Reglan 5-fluorouracil (5-FU)-loaded cellulose acetate (CA) core-shell particles in polyvinylpyrrolidone (PVP) matrix. Microscopic observations these demonstrated solid cross section loaded particles. X-ray diffraction Fourier-transform infrared tests verified that 5-FU showed amorphous states fine compatibilities polymeric matrices, i.e., PVP CA, respectively. vitro dissolution indicated able desired asynchronous dual-drug delivery, fast release Reglan, sustained 5-FU. controlled mechanisms shown be an erosion mechanism typical Fickian diffusion protocols reported herein pioneer approach fabricating biomaterials multiple drugs, each its own behavior, synergistic cancer treatment.

The rising CO2 concentration in the atmosphere contributes significantly to global warming, necessitating effective carbon capture techniques. Amine-based solvents are widely employed for chemisorption of CO2, although they have drawbacks, such as degradation, corrosion, and high regeneration energy requirements. Physical adsorption utilizing microporous adsorbents is a viable alternative that offers excellent efficiency selectivity capture. This work presents facile one-pot synthesis 3D-triptycene-containing hyper-cross-linked polymer (TBPP-OH) possessing hydroxyl groups. presence triptycene units TBPP-OH polymeric structure gives several desirable features, inherent microporosity, larger surface area, improved thermal stability. showed considerable microporosity (%Vmic = 70%), BET-specific area (SABET) 838 m2 g–1, good stability (Td 372 °C char yield > 60%) which makes it promising adsorbent A strong affinity was shown by with Qst 32.9 kJ/mol demonstrating superior capacity 2.77 mmol/g at 273 K 1 bar pressure where volume micropore plays significant role. values over N2 CH4 were also estimated be reasonably indicating potential separation different applications. mechanism investigated using Langmuir dual-site models.
