The present invention pertains to a method for using a boron-doped hierarchical porous carbon material as a catalyst for electrochemical synthesis of hydrogen peroxide, wherein the boron-doped hierarchical porous carbon material is produced by reacting a reducing agent or a mixture of a reducing agent and a nano-template with carbon dioxide-containing exhaust gas or production process waste gas at high temperature. The boron-containing hierarchical porous carbon material produced by the present invention is eco-friendly due to being synthesized from carbon dioxide under relatively mild conditions (atmospheric pressure), and can be used as a two-electron catalyst for an oxygen reduction reaction for electrochemical synthesis of hydrogen peroxide due to the doped heterogeneous boron and the hierarchical existence of micropores and mesopores.

The present disclosure relates to a fine particle-trapping sensor including: a plasmonic hotspot layer formed of a first metal; and a trapping layer formed of a second material. The inventors of the present disclosure have made extensive research efforts to develop a more effective and novel sensor for the real-time and high-sensitivity detection of droplets emitted from the oral cavity. As a result, the inventors have developed an alloy composite nanostructure including a Raman sensor layer, formed of a metal, and a trapping layer formed of a dielectric material, and have found that, when the ratio between the two layers is adjusted, the alloy composite nanostructure effectively traps respiratory droplets rapidly emitted from the oral cavity and detects coronavirus (SARS-CoV-2 lysate) in the respiratory droplets at a concentration of 10 pfu/ml, indicating that the composite nanostructure may be very advantageously used in the field of fine particle trapping.

Synthetic sRNA for inhibiting prokaryote gene expression is described, which includes (i) an Hfq binding site and (ii) a region that forms a complementary bond with a target gene mRNA. Vectors encoding the synthetic sRNA are described, as well as recombinant prokaryotes transformed with such vectors, methods of inhibiting prokaryote gene expression, and methods of gene screening and strain improvement. The synthetic sRNA is able to control single and multiple target genes at a time, and is particularly useful for inhibiting a gene expression of Gram-positive bacteria, e.g., in a recombinant Corynebacterium for mass production of high value products that do not require fossil fuels with associated environmental problems.
