Depositing manganese dioxide (MnO2) onto three-dimensional (3D) porous scaffolds—such as carbon lattices, nickel foam, or graphene frameworks—is a widely used strategy in developing high-performance electrochemical devices like supercapacitors, batteries, and catalysts.The primary objective is to build a hybrid structure that overcomes the natural material limitations of MnO2 while maximizing its high energy storage capabilities. But conventional MnO2 electrodeposition has a number of limitations. Conventional MnO2 electrodeposition tends to form thick coatings only on the outer surfaces of porous substrates. This excessive surface growth leads to pore blockage and poor penetration into the internal structure, impeding electrolyte access and reducing ion transport efficiency. This leads to low utilization of the available surface area and active material, severely limiting electrode performance. Achieving both high mass loading and coating uniformity remains a major challenge. Existing methods such as hydrothermal synthesis often suffer from inherently low loading (typically < 40 mg cm-2), which constrains device energy density and practicality. MnO2 nucleation is dominated by random and large island growth, resulting in thick, non-uniform films with thickness gradients that hinder charge and ion transfer kinetics.  Highly loaded electrodes prepared by conventional methods exhibit thick MnO2 coating often show poor electrochemical kinetics due to poor electron/ion conductivity.Finally, there is a lack of controlled interface regulation during electrodeposition.   

Researchers at the University of California, Davis have developed a compact two-photon miniscope designed to support high-resolution neural activity imaging over an expanded field of view in freely moving animals. The system achieves a favorable balance between imaging performance and device footprint, enabling large-scale neural observations while minimizing interference with natural behavior.

Professors Edward Zagha and Huinan Liu at the University of California, Riverside, have developed the Intra-Arterial Drug Delivery (IADD) system to deliver highly localized, organ-specific drug targeting utilizing the body’s vascular network as a direct perfusion conduit.The IADD system targets a specific non-vessel organ or tissue by positioning a biodegradable, drug-eluting device within an upstream feeding artery. The device slowly releases the agent into the local arterial blood supply over an extended duration. This technology is advantageous because it establishes robust target-organ enrichment while vastly minimizing systemic circulation exposure and its accompanying adverse reactions.  Fig. 1: The focal delivery of dexamethasone (DEX) loaded UCR IADD device after a 7-day in vivo implantation in the left renal artery. The IADD system delivered 600x the localized concentration of DEX when compared to oral administration.  

Researchers at the University of California, Davis have developed a radiotherapy device that integrates ultra-high magnetic fields with high-energy X-ray beams to precisely target tumors while minimizing radiation exposure to healthy tissue.

Electronic (also called chemiresistive) gas sensors based on semiconducting metal oxides (SMOX) are widely used to detect hazardous gases for environmental, health and safety monitoring, including industrial processes and air quality assessment, among others.  However, volatile siloxanes, which are organosilicon compounds prevalent in personal care products and other consumer materials, can severely degrade the performance of these sensors (so-called siloxane poisoning), eventually leading to their failure.To address this vulnerability, UC Berkeley researchers have developed an effective mitigation strategy that applies an ultra thin protective layer over the sensing material. This barrier effectively suppresses siloxane induced deactivation by altering the adsorption energetics and reaction pathways of the interferents. The interfacial electronic interactions and protection mechanisms have been comprehensively validated through density functional theory calculations and rigorous material characterization techniques, offering a robust framework for designing resilient environmental sensors.
