Purpose: To study the effect of different ways of pulling the drilling burs and cooling systems on alveolar bone temperature of the surgical area, and explore the changes of temperature field in dental implants.
Methods: Forty-eight unified standard artificial (nylon) bone blocks were fabricated and divided into 6 groups according to different drilling pulling ways and cooling systems. The changes of bone temperature field were detected in 6 groups, and the highest temperature in temperature field was measured and recorded. The date was analyzed with SPSS 12.0 software package for ANOVA.
Results: The temperature in the surgical area using internal cooling systems under the same drilling pulling was lower than using external cooling systems. The temperature in the surgical area using secondary drilling pulling way was lower than using direct drilling methods under the same cooling systems. The temperature in the surgical area using secondary drilling pulling way was the lowest when internal cooling systems was adopted(P<0.05).
Conclusions: Drilling pulling way and internal cooling systems can effectively reduce the temperature in the surgical area, lessen heat production and improve the success rate of dental implants.

Engine oil is a valuable source of information on the technical condition of the drive unit. Under the influence of many factors, including operating conditions, time, high temperature, and various types of contamination, the oil gradually degrades, which can result in serious engine damage. The subject of the article focuses on an attempt to answer the questions of how engine failure affects the degradation of engine oil and whether we can use this knowledge to detect potential problems in public transport vehicles at an early stage.

As the proportion of solar energy in the global energy mix increases, photovoltaic cells have emerged as one of the fastest-growing technologies in the renewable energy sector. However, photovoltaics utilize only a limited portion of the incident solar spectrum, resulting in significant amounts of light energy being wasted as heat. This excess heat raises the surface temperature of photovoltaic cells, which in turn reduces their overall efficiency.

Air-conditioning systems, composed mainly of humidity control and heat reallocation units, play a pivotal role in upholding superior air quality and human well-being across diverse environments ranging from international space stations and pharmacies to granaries and cultural relic preservation sites, and to commercial and residential buildings. The adoption of sorbent water as the working pair and low-grade renewable or waste heat in adsorption-driven air-conditioning presents a state-of-the-art solution, notably for its energy efficiency and eco-friendliness vis-à-vis conventional electricity-driven vapor compression cycles. Here, we introduce a rational π-extension strategy to engineer an ultrarobust and highly porous zirconium metal-organic framework (Zr-MOF).

High-performance boiling surfaces are in great demand for efficient cooling of high-heat-flux devices. Although various micro-/nano-structured surfaces have been engineered toward higher surface wettability and wickability for enhanced boiling, the design and fabrication of surface structures for realizing both high critical heat flux (CHF) and high heat transfer coefficient (HTC) remain a key challenge. Here, a novel "electrode-transpose" all-electrochemical strategy is proposed to create superhydrophilic microporous surfaces with higher dendrites and larger pores by simply adding an electrochemical etching step prior to the multiple electrochemical deposition steps.
