The authors demonstrate a transparent resistive switching devices entirely fabricated by open‐air approaches, without a deposition chamber. The threshold voltage can be tuned by adjusting the density of AgNWs, while maintaining a high LRS/HRS ratio. They show the effect of oxide thickness on the threshold‐switching phenomenon, thus shedding light on...

Lipid nanoparticles encapsulating small interfering ribonucleic acids are developed that block two essential pathways for cancer cell survival. Targeting of metastasized ovarian cancer cells is further enhanced by coating nanoparticles with hyaluronan. Robust gene silencing in key tissues involved in ovarian cancer pathophysiology in an advanced ovarian...

Porous all‐carbon hybrid nanomaterials combining an electrically conductive domain and a highly functional carbon can be used to overcome the “functionality‐conductivity‐dilemma” that remains a huge drawback for single compounds. Such materials show extraordinary performance for many electrochemical applications such as energy storage and electrocatalysis,...

Patterned sapphire substrates (PSS) are proposed to improve the optoelectronic properties of 2D layered materials. An enhanced dynamic distribution of local electric field and concentrated photon excitons across MoS2/PSS interface are revealed by the finite‐difference time‐domain simulation. This work provides a guide for fabricating advanced MoS2‐based...
