“…However, the decomposition of H 2 O 2 in the stainless steel capillary micoreactor was much faster than that in the PFA capillary at the same theoretical residence time and temperature. This was because the stainless steel capillary surface itself catalyzes the H 2 O 2 decomposition …”

“…Obviously, it is difficult to control reaction temperatures precisely in batch reactors under harsh conditions (e.g., high H 2 O 2 concentrations and high temperatures) since the hydrogen peroxide decomposition is highly exothermic. In the worst case, the substantial uncontrolled decomposition in batch reactors can lead to the formation of hotspots and even an explosion …”

On the background of the direct adipic acid synthesis from cyclohexene and H2O2, a kinetic model was derived for the H2O2 decomposition catalyzed by sodium tungstate at high H2O2 concentrations and high temperatures. A perfluoroalkoxy (PFA) and a stainless steel micro‐flow capillary match commonly used microreactor materials. In the PFA capillary, the decomposition of hydrogen peroxide increased with residence time, reaction temperature and catalyst loading. The reaction order with respect to hydrogen peroxide and sodium tungstate was zero and one, respectively. Simulated data fit well with experimental data in the PFA capillary. While showing a similar trend as that in the PFA capillary, the stainless steel capillary exhibited much higher reaction rates. The steel surface participated in the decomposition process as a heterogeneous catalyst. Key influencing factors of the H2O2 decomposition provided some clues on the reaction mechanism of the adipic acid synthesis and its process optimization. © 2016 American Institute of Chemical Engineers AIChE J, 63: 689–697, 2017

“…Clearly, the danger in this method is having the ability to carefully and precisely control the ROS in order to minimize damage to healthy, normal skin around the abnormal lesions. Currently, the most common concentrations of H 2 O 2 available to the public are 3% and 30% [17]. It is possible to purchase these concentrations of H 2 O 2 on websites such as e-bay and Amazon.…”

Seborrheic Keratoses (SKs) are one of the most common dermatologic lesions seen by dermatologists. They are biologically benign and do not usually require removal for medical reasons; however, many patients choose removal due to cosmetic preferences. Currently, cryotherapy (liquid nitrogen spray) is the most common mode of removal [1]. Although patients often desire an effective topical treatment, few have been developed that rival the effects of cryotherapy. This article aims to review current available topical treatments, with a particular focus on both the benefits and potential pitfalls of a novel treatment, concentrated Hydrogen Peroxide (H2O2).

“…Hypergolic H 2 O 2 /kerosene bipropellant is an effective alternative for the present propulsion systems [10,11], in which hydrogen peroxide at a high concentration becomes an oxidizer to kerosene. A propellant based on hydrogen peroxide has a number of advantages, such as high density, zero toxicity, and high specific impulse [12].…”

Future space missions are considering the use of green space propulsion, and H 2 O 2 /kerosene bipropellant is one of effective alternatives for rocket propellant. In addition, for a 100-N-class thruster of H 2 O 2 /kerosene, it is important to design the proper injector. In this study, according to different values of the geometric constant A which determines the initial swirl intensity of the injected fluid, five coaxial swirl injectors are designed to check the thruster's performance. From the test and experiment results, it is found that with an increase in A, coaxial-swirl injectors can aid in the mixing of oxidant and fuel but increase the average temperature of faceplate, thus significantly reducing the flame length. However, a large or small value of A is not conductive to improve the combustion efficiency. In addition, the pressure oscillation (P ins ) inside of the chamber gradually becomes intense. Among all cases, Case 3 ( A = 3.0), exhibits optimal performance for a 100-N-class H 2 O 2 /kerosene thruster.
