The occupational stressors has an effect on overall health and dental health. Oral health is a vital aspect of general health. The current study was performed to assess the periodontitis among thermal power station workers in South India. Pilot study was done for 52 mine workers and based on the periodontal disease prevalence among them, the sample size was calculated as 603 subjects. The data collection was done using WHO 1997 proforma. Among the total study population, about 92 (30%) thermal power station 1 workers and 83 (28.1%) thermal power station 2 workers had pocket 4-5 mm, one (0.2%) thermal power station, 2 worker had pocket 6 mm or more thermal power station I workers, and 23 (7.8%) thermal power station 2 workers had 6 - 8 mm attachment loss. Only 1 (0.3%) thermal power station I worker had 9 - 11 mm attachment loss. In the current study, nearly 70% mine workers had calculus, nearly 30% had pocket 4-5 mm, and only 0.2% Mine II workers had pocket measuring 6 mm or more.

The inadequate thermal insulation of the building envelope contributes significantly to the high power consumption of air conditioners in houses. A crucial factor in raising a building's energy efficiency involves utilizing bricks with high thermal resistance. This issue is accompanied by another critical challenge: recycling and disposing of waste in a way that is both economically and environmentally beneficial, including using it to fuel industrial growth, in order to reduce the harmful effects of waste on the environment as waste generation in our societies grows.

Thermoelectric (TE) performance in materials is often constrained by the strong coupling between carrier and phonon transport, necessitating trade-offs between electrical and thermal properties that limit improvements in the figure of merit (). Herein, a novel strategy is proposed to achieve simultaneous energy filtering and enhanced phonon scattering, effectively optimizing the TE properties of CoSb-based skutterudites. By introducing CuTe nanoprecipitates into the YbCoSb matrix, interfacial barriers are formed, which selectively filter low-energy charge carriers, significantly improving the Seebeck coefficient while maintaining high carrier mobility.

This study presents a novel optoporation technique using a titanium-coated TiO microstructure (TMS) device activated by an infrared diode laser for highly efficient intracellular delivery. The TMS device, fabricated with 120 nm titanium coating on a titanium dioxide (TiO) microstructure containing microneedles (height ∼2 μm and width ∼4.5 μm), demonstrates enhanced biocompatibility and thermal conductivity compared to the conventional TiO microstructure (MS).

Along with the development of miniaturization, integration, and high power of electronic chips in the 5G and artificial intelligence era and their urgent need for technologies enabled to solve high heat flux dissipation in limited space, investigating bioinspired extreme superwettability surfaces with high-efficiency condensation heat transfer (CHT) performance has attracted great interest in academic and industrial communities. Compared with filmwise condensation of flat hydrophilic surfaces featured with continuous liquid films, dropwise condensation of flat hydrophobic surfaces is a more efficient type of energy transport way. However, discrete condensate drops can only shed off the hydrophobic flat surfaces under gravity until their sizes reach the capillary length of liquid, e.
