In a previous study, we found that plasma can enhance spore germination and α-amylase secretion in A. oryzae, beneficial fungus used fermentation. To confirm this, the current investigated effects of on development using an enlarged sample size different source: jet. There was ~10% (p < 0.01) increase upon non-thermal atmospheric pressure jet (NTAPPJ) treatment for 5 min 10 min, as compared ...

Clostridium difficile is a spore forming bacterium and the leading cause of colitis and antibiotic associated diarrhoea in the developed world. Spores produced by C. difficile are robust and can remain viable for months, leading to prolonged healthcare-associated outbreaks with high mortality. Exposure of C. difficile spores to a novel, non-thermal atmospheric pressure gas plasma was assessed. ...

The conventional light source used for tooth bleaching has the potential to cause thermal damage, and the actual role of the light source is doubtful. In this study, we evaluated bleaching efficacy, temperature, and morphological safety after tooth bleaching with nonthermal atmospheric pressure plasma. Tooth bleaching combined with plasma had improved efficacy in providing a higher level of bri...

Excessive or persistent infection is a major contributing factor in impeding chronic wound healing. Wound bed preparations using antiseptics do not necessarily target the entire bacterial spectrum, and highly proliferating granulation tissue may be sensitive to cytotoxic effects, impairing repair. Non-thermal gas atmospheric pressure plasmas are partially ionized gases that contain reactive par...

As a result of both the better understanding of complex plasma phenomena and the development of new plasma sources in the past few years, plasma medicine has developed into an innovative field of research showing high potential. While thermal plasmas have long been used in various medical fields (for instance for cauterization and sterilization of medical instruments), current research mainly f...

We present a novel approach to remove the structure-directing agent (SDA) from as-synthesized zeolites using an atmospheric pressure plasma jet (APPJ). This reduces the time required to less than 60 seconds as compared to the existing thermal calcination, whose durations range from hours to days. The highly reactive plasma also results in a pronounced Q(3)-to-Q(4) transformation in the pure-sil...

The failure of plasma-sprayed thermal barrier coatings (TBCs) during service is usually related to the cracking behavior. In this study, TBCs were prepared with two kinds agglomerated sintered yttria-stabilized zirconia (YSZ) powders different particle sizes. evolution mechanical properties and crack propagation behavior whole life stage studied by a shock test. effect powder size on was analyz...
