These electrolyzers typically consist of two electrodes, anode and cathode, separated by a diaphragm which is often Zirfon™, a porous composite separator material composed of a polysulfone matrix and ZrO in powder form. This porous membrane allows for the ion transport in the electrolyte and separates the product gases hydrogen and oxygen from each other. However, there are dissolved product gases in the liquid electrolyte that cross the porous membrane via diffusion. The main reason for this crossover rate is the fact that the aqueous liquid electrolyte phase is supersaturated with hydrogen on one side and oxygen on the other. We are proposing to add a layer of coating to the outside faces of the Zirfon membrane to promote the formation of hydrogen/oxygen bubbles outside of the membrane and thus reduce the hydrogen and oxygen crossover.</div></div>","PeriodicalId":100728,"journal":{"name":"Invention Disclosure","volume":"5 ","pages":"Article 100043"},"PeriodicalIF":0.0,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In clinical settings, it is important that allied-health professionals can measure body composition to determine potential risk of obesity-related health complications, as well as to track progress during pharmacological, dietary, or physical activity programs aimed at fat loss. In sport-performance settings, athletes must measure and track improvements in Fat-Free Mass as it is related to strength and power. However, traditional body composition assessment techniques are expensive, not portable, and require a great deal of technical expertise to administer. However, recently anthropometric measurements of body size and shape have been used to estimate body composition, overcoming many of the barriers experienced with other techniques. The methods and systems described in this invention measure the anatomical dimensions of an individual from a single two-dimensional (2D) digital image. The digital image is taken from the front/anterior view using a mobile, handheld communication device. The linear measurements are used to estimate the body volume of the individual, from which total body density can be calculated from the estimated body volume and body weight. Body composition (Fat Mass and Fat-Free Mass) of the individual is derived from density using known mathematical conversion formulas.</div></div>","PeriodicalId":100728,"journal":{"name":"Invention Disclosure","volume":"5 ","pages":"Article 100040"},"PeriodicalIF":0.0,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144722426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
