As environmental concerns from fossil fuel consumption intensify, larg.-scale energ. storag. becomes imperative for the integ.ation of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing.org.nic molecules, are positioned as a key technolog. for this purpose. This review explores the g.owing.field of symmetric org.nic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric desig.s based on unique active materials for each electrode, symmetric ORFBs involve a sing.e bipolar species for both electrodes. This review hig.lig.ts the benefits of a symmetric desig., and categ.rizes five distinct classes of org.nic bipolar molecules used in both aqueous and non-aqueous solvents. By providing.a comprehensive overview of their cell cycling.and performance characteristics, the streng.hs and weaknesses of the diverse categ.ries of bipolar molecules are hig.lig.ted for both solvent systems, as are opportunities for future development. This should g.ide new research directions and advance the development of practical symmetric ORFBs.

The neuromuscular junction(NMJ)is an essential synaptic structure composed of motor neurons,skeletal muscles,and g.ial cells that orchestrate the critical process of muscle contraction(Li et al.,2018).The typical NMJ structure is classically described as having.a“pretzel-like”shape in mice(Fig.re 1),whereas human NMJs have a smaller,frag.ented structure throug.out *** NMJs exhibit smaller or frag.ented endplates,partial denervation,reduced numbers of synaptic vesicles,abnormal presynaptic mitochondria,and dysfunctional perisynaptic Schwann cells(Alhindi et al.,2022).

There have been sig.ificant advances in the application of critical state,CS,in liquefaction potential *** was done by comparing.state parameter,j with estimated characteristic cyclic stress ratio,CSR due to an earthquake.A cyclic resistance ratio,CRR curve,which can be determined from cyclic liquefaction tests,separates historical liquefied and non-liquefied data points(j,CSR).On the other hand,the concepts of equivalent g.anular state parameter,j*,which was developed for sands with fines,can be used in lieu j to provide a unifying.framework for characterizing.the undrained response of sands with non/low plasticity fines,irrespective of fines content(fc).The present work combines these two propositions,and by merely substituting.j*for j into the aforementioned CS approach to capture the influence of fc.A series of static and cyclic triaxial tests were conducted,separately and independently of the concept of j*,for sand with up to fc of 30%.The clean sand was collected from Sabarmati river belt at Ahmedabad city in India which was severely affected during.the Bhuj earthquake,*** experimental data g.ve a sing.e relation for CRR and j*which was then used to assess liquefaction potential for a SPT based case study,where fc varies along.the *** prediction matched with the field observation.

Fluoride based g.asses with composition CaF_2-ZnF_2-Bi_2 O_3-B_2 O_3 doped with chromium ions have been investig.ted using.physical, optical, electron paramag.etic resonance(EPR), Fourier-transform infrared spectroscopy(FTIR), and Raman studies. The amorphous nature of samples was confirmed from x-ray diffraction spectra. The density is evaluated from the Archimedes principle and the values of optical band g.p and Urbach energ. values were evaluated from the optical absorption spectra. Thus, molar volume, refractive index, etc., were also evaluated. The observed decrease in density and the optical band g.p with CaF2 is explained using.the crystalline density of metal fluorides and the ionicity of fluorine ions,respectively. The three peaks near 450 nm, 606 nm, and 720 nm, which are shown in the absorption spectra, are accredited to ~4 A)(2 g. → ~4 T_(1 g., ~4 A_(2 g.→ ~4 T_(2 g., ~4 A_(2 g.→~2 E transitions, respectively. Resonance sig.als at g. 4.82 and g. 1.99 were observed in EPR spectra which are assig.ed. FTIR and Raman analysis were carried out to examine the impact of metal fluorides on the structure of bismuth borate g.asses.

Inducible heat shock protein 70 kD (HSP-70i) has been shown to protect cells, tissues, and org.ns from harmful assaults in in vivo and in vitro experimental models. Hemorrhag.c shock followed by resuscitation is the principal cause of death among.trauma patients and soldiers in the battlefield. Althoug. the underlying.mechanisms are still not fully understood, it has been shown that nitric oxide (NO) overproduction and inducible nitric oxide synthase (iNOS) over expression play important roles in producing.injury caused by hemorrhag.c shock including.increases in polymorpho nuclear neutrophils (PMN) infiltration to injured tissues and leukotriene B4 (LTB4) g.neration. Moreover, transcription factors responsible for iNOS expression are also altered by hemorrhag. and resuscitation. It has been evident that either up-reg.lation of HSP-70i or down-reg.lation of iNOS can limit tissue injury caused by ischemia/reperfusion or hemorrhag./resuscitation. In our laboratory, g.ldanamycin, a member of ansamycin famil
