Synthetic micro- and nanomotors (MNMs) have emerged as a vibrant research field in multidisciplinary nanotechnology with proof-of-concept applications various disciplines.

Photovoltaics (PV) is the leading renewable energy harvesting technology. Thus, there a remarkable strive to enhance light capability of state-of-the-art solar cells. The major issue common all cell types that they utilize only limited portion spectrum, mostly in visible range, as active semiconductor materials suffer from intrinsic absorption thresholds. As result, photons below and above these threshold values do not contribute electricity generation. A plausible solution performance...

Here, we summarize recent developments which utilize the potential of microfluidic devices for energy generation.

Manganese oxide (MnO2 ) based micromotors exhibiting a dual effect, that is, catalytic degradation and adsorptive bubble separation, were employed for water remediation. The effect of MnO2 microparticles led to greater than 90 % decolorization non-biodegradable organic dyes in just 1 h, without the need external agitation or generation. These findings suggest high potential decontamination pollutants from wastewaters natural reserves.

Chemically powered micromotors represent an exciting research area in nanotechnology. Such artificial devices are typically driven by catalytic bubble formation, taking place at the solid-liquid interface. Platinum has been most frequently used for fabrication of different due to its superior efficiency. Other materials suffer from slow speeds and require very high concentrations chemical fuel. Here, we report preparation characterization fast moving based on manganese oxide (MnO2) with...

Photon-upconversion materials are capable of converting low energy infrared light into higher visible or ultraviolet light.

Manganese oxide (MnO2) has recently emerged as a promising alternate material for the fabrication of self-propelled micromotors. Platinum (Pt) been traditionally used catalytic this purpose. However, high cost associated with Pt restricts its widespread use toward practical applications where large amounts are required. MnO2 exists in different crystalline forms (polymorphs), which govern behavior. In spite this, recent reports on based micromotors have seldom reported polymorphic form...

Abstract Platinum‐based micromotors have shown many exciting applications when functionalized using gold–thiol chemistry. However, thiols are known to bind the Pt surface, which can lead serious deactivation of catalyst. In this paper, it is demonstrated that MnO 2 be used protect Pt‐based prior thiol treatment, thus fully avoiding catalyst poisoning. This approach will greatly facilitate use for toxicity has been a limiting factor.
