Pursuing high-level doping without deteriorating crystallinity is prohibitively difficult but scientifically crucial to unleashing the hidden power of materials. This study demonstrates an effective route for maintaining lattice integrity during the combustion chemical vapor deposition of highly conductive boron-doped diamonds (BDDs) through laser vibrational excitation of a growth-critical radical, boron dihydride (BH2). The improved diamond crystallinity is attributed to a laser-enabled, thermal nonequilibrium suppression of the relative abundance of boron hydrides (BH), whose excessive presence induces boron segregation and disturbs the crystallization. The BDDs show a boron concentration of 4.3 × 1021 cm−3, a film resistivity of 28.1 milliohm·cm, and hole mobility of 55.6 cm2 V−1 s−1, outperforming a commercial BDD. The highly conductive and crystalline BDDs exhibit enhanced efficiency in sensing glucose, confirming the advantages of laser excitation in producing high-performance BDD sensors. Regaining crystallinity with laser excitation in doping process could remove the long-standing bottlenecks in semiconductor industry.

“…In addition, the incompleteness of semicircle of HNS‐Cu 2 O/N‐rGO/GCE is caused by the large conductance of electric bilayer at the electrode surface. The large conductance is generally due to the large surface area attributable to the sinks . Thus, the HNS‐Cu 2 O/N‐rGO/GCE electrode possesses superior electrochemical performance than the other electrodes.…”

Nitrogen‐doped reduced graphene oxide (N‐rGO) was obtained via high temperature heat treatment using ammonia as a nitrogen source. EDS and XPS tests revealed that the nitrogen atoms have been doped into the skeleton of graphene successfully. On this basis, hollow nanospherical cuprous oxide supported by N‐rGO (HNS‐Cu2O/N‐rGO) was synthesized by chemical precipitation as electrode materials for detection of glucose. TEM test showed that the hollow spherical cuprous oxide has been successfully supported on the surface of N‐rGO. In the case of electrochemical studies, the HNS‐Cu2O/N‐rGO modified glass carbon electrode presented a linear range from 4 μM to 2.37 mM for glucose detection with a sensitivity of 2488.8 μA⋅mM−1⋅cm−2, a detection limit of 2.28 μM (S/N=3) and fast amperometric response. Furthermore, the nanocomposite displayed good selectivity for glucose detection in the presence of interferences. The entire analysis demonstrates the applicability of HNS‐Cu2O/N‐rGO nanocomposite as one of the futuristic sensing material for glucose detection.

The chemical stability and electrocatalytic properties of boron‐doped diamond (BDD) electrodes give rise to various applications. While wastewater treatment is the most widely studied field, the use of BDD for soil remediation and environmental sensing is currently investigated more and more. With regards to soil remediation, promising results have been reported for the treatment of soil washing solutions. Anodic oxidation using BDD at high current density allows high mineralization rates of biorefractory soil pollutants and extracting agents to be reached. At low current density, selective degradation of target pollutants has been achieved, thus allowing the reuse of extracting agents for further soil washing steps. BDD‐based electrochemical sensors have been studied for chemical oxygen demand determination, pesticide/pharmaceutical detection as well as other applications such as pH, O2 and analysis of various organic and inorganic compounds. Low detection limits, wide linear ranges and low standard deviations have been achieved. The main reasons behind the superiority of BDD sensors are the chemical stability, wide applicability and resistance of BDD towards biofouling. The beauty of BDD sensing is that it can work for a variety of organic and inorganic compounds under many physicochemical parameters.
