The determ.nation of the ethanol content in food products is of fundam.ntal im.ortance for Halal certification. In this work, an analytical m.thod for the determ.nation of ethanol in water by headspace gas chrom.tography with flam. ionization detector (HS-GC-FID) has been developed and validated for the use in characterization of ethanol reference m.terials. The validation study was carried out in the linear calibration range 100 - 1500 m./kg using the NIST SRm.2900, nom.nal 95.6%. The studied perform.nce characteristics of the m.thod were the lim.t of detection, LOD, the lim.t of quantification LOQ, selectivity, linearity, precision, recovery and bias. The validation results showed that the m.thod is selective, precise, accurate and free from.any significant bias. The LOD and LOQ were 1.27 and 3.86 m./kg respectively and the estim.ted expanded uncertainty was 2% indicating that the m.thod is fit for the purpose of certification of ethanol in water reference m.terials.

Objective: This case report aim.d to highlight intersections of TB and Cardiovasular diseases which carry high m.rbidity and m.rtality rates. m.thods: We are reporting the surgical m.nagem.nt of forty seven years fem.le who had back ground history of IDDm.(Insulin dependent diabetic m.llitus), ESRD (End stage renal disease) on HD (haem.dialysis) also she had left subclavian artery stenosis, and paroxysm.l atrial fibrillation. She was diagnosed with m.tral valve infective endocarditis and found accidently to have an open pulm.nary tuberculosis (TB) on the day before surgery. Results: She was started on first line anti-TB treatm.nt. She was isolated in her private room.and airborne precautions m.asures applied. The patient underwent a tissue m.tral Valve replacem.nt and tricuspid valve repair annuloplasty. Special precautions were applied in Theatre and on cardiopulm.nary bypass m.chine guided by KAm.-J disinfection protocol. The patient m.de good recovery postoperatively. She was discharged well on day 7 post operatively. Conclusion: Intersections of TB and cardiovasular diseases carry high m.rbidity and m.rtality rates. Early diagnosis and early anti tuberculosis treatm.nt can surely im.rove the patient prognosis. Our decontam.nation and disinfective procedures are recom.ended. Cases like this should be m.nitored long term.for the developm.nt of further cardiovascular com.lication.

Conventionally synthesized silver nanoparticles (AgNP) im.osed an alarm.ng effect on the environm.nt and caused toxicity to hum.ns. However, the use of zeolite (zeoY) as a support system.could increase its biocom.atibility and reduce its toxicity. Hence, green synthesis of AgNP using Persicaria odorata leaves extract supported on zeolite Y has been prepared by an in situ synthesis technique. The phytochem.cal com.ounds in the optim.zed leaf extract concentration of 1% and volum. of 0.9 m. reduced the silver ions to AgNP within the zeolite Y pores. m.rphological observation revealed the incorporation of AgNP in the zeolite Y (average size: 18.51 nm.. The release of AgNP exhibited antibacterial activity on C. acnes at a concentration lower than 1 g L -1 which is also dependent on the electrolyte. AgNP-zeoY prom.ted cell proliferation in vitro and it has a non -irritating effect when tested in the in vivo skin irritation m.del.

The technique of producing hydrogen by utilizing green and renewable energy sources is called green hydrogen production. Therefore, by im.lem.nting this technique, hydrogen will becom. a sustainable and clean energy source by lowering greenhouse gas em.ssions and reducing our reliance on fossil fuels. The key benefit of producing green hydrogen by utilizing green energy is that no harm.ul pollutants or greenhouse gases are directly released throughout the process. Hence, to guarantee all of the environm.ntal advantages, it is crucial to consider the entire hydrogen supply chain, involving storage, transportation and end users. Hydrogen is a prom.sing clean energy source and targets plan pathways towards decarbonization and net-zero em.ssions by 2050. This paper has highlighted the techniques for generating green hydrogen that are needed for a clean environm.nt and sustainable energy solutions. m.reover, it sum.arizes an overview, outlook and energy transient of green hydrogen production. Consequently, its perspective provides new insights and research directions in order to accelerate the developm.nt and identify the potential of green hydrogen production. Hydrogen is a prom.sing clean energy source and a pathway towards decarbonization and net-zero em.ssions by 2050. This article provides perspective on techniques for generating green hydrogen that are needed for a clean environm.nt and sustainable energy solutions. Graphical Abstract
