Asymmetric Dialysis: Truly Unified and Simultaneous Single‐Pass Concentration and Buffer Exchange
Biotechnology and Bioengineering, EarlyView.Asymmetric dialysis, a novel one‐step continuous process combining ultrafiltration and diafiltration, achieves high product concentrations (up to 200 g/L) with low pressures and reduces buffer consumption by 75% compared to conventional methods. This sustainable, low‐cost technology demonstrates significant potential for integration into continuous ...

Halide perovskites in wide‐spectrum photodetection
Bulletin of the Korean Chemical Society, EarlyView.Recent advances in perovskite‐based photodetectors (PPDs), phototransistors, and photoconductors are technically discussed in this review. Moreover, the mechanism behind different harvesting processes in perovskite following the energy of photons is explained, where the gamma or x‐rays are ionizing.
