Nanoporous Materials
In article number 2300697, Li Sheng, Hong Xu, Cheng Wang, Xiangming He, and co‐workers provide a method (i.e. electrospinning) to convert sulfonated polymers into high‐performance lithium battery separators. The nanofibrous Nafion separator swelled in liquid electrolytes has in situ generated nanochannels, efficiently accelerating lithium ion transport.
Sulfonated polymers have long been used as proton‐conducting materials in fuel cells, and their ionic transport features are highly attractive for electrolytes in lithium‐ion/metal batteries (LIBs/LMBs). However, most studies are still based on a preconceived notion of using them directly as polymeric ionic carriers, which precludes exploring them as nanoporous media to construct efficient lithium...
With the increasing demands for novel flexible organic electronic devices, conductive polymers are now becoming the rising star for reaching such targets, which has witnessed significant breakthroughs in the fields of thermoelectric devices, solar cells, sensors, and hydrogels during the past decade due to their outstanding conductivity, solution‐processing ability, as well as tailorability. However,...
Synergetic Prostate Cancer Therapies
In article number 2207077, Li Zhang, Yunjiao Zhang, Chaozhao Liang, and co‐workers propose intratumoral implantation of micromagnets to actively attract intravenously‐injected magnetic PEGylated manganese‐zinc ferrite nanocrystals (PMZFNs) from blood vessels into tumor tissue. PMZFNs exert relatively durable tumoricidal effects by inducing ferroptotic/immunogenic...
Therapeutic efficacy for prostate cancer is highly restricted by insufficient drug accumulation and the resistance to apoptosis and immunogenic cell death (ICD). Although enhanced permeability and retention (EPR) effect of magnetic nanomaterials could benefit from external magnetic field, it falls off rapidly with increased distance from magnet surface. Considering the deep location of prostate in...
Biologically plausible computing systems require fine‐grain tuning of analog synaptic characteristics. In this study, lithium‐doped silicate resistive random access memory with a titanium nitride (TiN) electrode mimicking biological synapses is demonstrated. Biological plausibility of this RRAM device is thought to occur due to the low ionization energy of lithium ions, which enables controllable...
