3D carbon foams have demonstrated their superiority in the field of microwave absorption recently, but the preparation processes of traditional graphene foams are complicated, while some novel carbon foams usually suffer from inadequate dielectric property. Herein, a simple “win–win” strategy is demonstrated to synchronously realize the construction of 3D Co/C foam and its surface decoration with...
Phenytoin (PHT) is a first‐line antiepileptic drug in clinics, which could decrease neuronal bioelectric activity by blocking the voltage‐operated sodium channels. However, the intrinsically low blood–brain‐barrier (BBB)‐crossing capability of PHT and upregulated expression level of the efflux transporter p‐glycoprotein (P‐gp) coded by the gene Abcb1 in epileptic neurons limit its efficacy in vivo...
The oxygen evolution reaction (OER) has significant effects on the water‐splitting process and rechargeable metal‐air batteries; however, the sluggish reaction kinetics caused by the four‐electron transfer process for transition metal catalysts hinder large‐scale commercialization in highly efficient electrochemical energy conversion devices. Herein, a magnetic heating‐assisted enhancement design...
Layered double‐hydroxide (LDH) has been considered an important class of electrocatalysts for the oxygen evolution reaction (OER), but the adsorption‐desorption behaviors of oxygen intermediates on its surface still remain unsatisfactory. Apart from transition‐metal doping to solve this electrocatalytic problem of LDH, rare‐earth (RE) species have sprung up as emerging dopants owing to their unique...
Resin derived hard carbons (HCs) generally demonstrate remarkable electrochemical performance for both sodium ion batteries (SIBs) and potassium‐ion batteries (KIBs), but their practical applications are hindered by their high price and high temperature pyrolysis (≈1500 °C). Herein, low‐cost pitch is coated on the resin surface to compromise the cost, and meanwhile manipulate the microstructure at...
Ferroptosis is a new form of regulated cell death with significant therapeutic prospect, but its application against drug‐resistant tumor cells is challenging due to their ability to effuse antitumor agents via p‐glycoprotein (P‐gp) and anti‐lipid peroxidation alkaline intracellular environment. Herein, an amorphous calcium phosphate (ACP)‐based nanoplatform is reported for the targeted combinational...
Optical imaging in the second near infrared region (NIR‐II, 1000–1700 nm) provides higher resolution and deeper penetration depth for accurate and real‐time vascular anatomy, blood dynamics, and function information, effectively contributing to the early diagnosis and curative effect assessment of vascular anomalies. Currently, NIR‐II optical imaging demonstrates encouraging results including long‐term...
Nanocatalytic tumor therapy is an emerging antitumor option that employs catalytically‐active inorganic nanostructures to produce tumor‐damaging reactive oxygen species. However, initiation of nanocatalytic reactions in the tumor intracellular environment is a challenge due to the reliance on acidic pH. By exploiting the pH‐selective multifaceted catalytic activities of Prussian blue‐based nanomaterials...
In drug delivery, the poor tumor perfusion results in disappointing therapeutic efficacy. Nanomedicines for photodynamic therapy (PDT) greatly need deep tumor penetration due to short lifespan and weak diffusion of the cytotoxic reactive oxygen species (ROS). The damage of only shallow cells can easily cause invasiveness and metastasis. Moreover, even if the nanomedicines enter into deeper lesion,...
