In the present study, a novel reverse electrodialysis (RED) stack with ultrathin lab-made pore-filling membranes and high-open-area spacer was proposed to enhance gross power density.
Abstract The oxygen evolution reaction (OER) is crucial for producing sustainable energy carriers. Herein, Ir (5 mol.%) doped inverse‐spinel NiFe 2 O 4 (Ir‐NFO) nanoparticles deposited on Ni foam (NF) by scalable solution casting are considered a promising OER electrocatalyst industrial deployments. Ir‐NFO/NF (with minimal lattice distortion uniform doping) provides an overpotential of 251 mV (intrinsically outperforming NFO/NF and benchmarking IrO /NF) extraordinary robustness over 130 days...
ABSTRACT T follicular helper (Tfh) cells are specialized providers of cognate B cell help, which is important in promoting the induction high-affinity antibody production germinal centers (GCs). Interleukin-6 (IL-6) and IL-21 have been known to play roles Tfh differentiation. Here, we demonstrate that IL-7 plays a pivotal role generation GC formation vivo , as treatment with anti-IL-7 neutralizing markedly impaired development IgG responses. Moreover, codelivery mouse Fc-fused (IL-7-mFc)...
Durable complete remission of metastatic renal cell carcinoma (RCC) has rarely been achieved with current treatment modalities. To solve this problem, alternative therapeutic options high efficacy and minimal side effects are strongly needed.Mesenchymal stem cells (MSC) were engineered to coexpress dodecameric TRAIL herpes simplex virus thymidine kinase (MSC/dTRAIL-TK). The antitumor MSCs expressing dTRAIL (MSC/dTRAIL) or HSV-TK alone (MSC/TK) MSC/dTRAIL-TK compared murine RCC using in vitro...
The effect of nitrogen type and content along with metal doping in hollow carbon spheres on oxygen reduction activity is described.
The regenerative potential of endothelial and hematopoietic progenitor cells in the heart may vary according to their origin. This study was designed compare functional effects CD133+ from human cord blood bone marrow a mouse model myocardial injury.5 x 10(5) (BM(CD133)) or (UCB(CD133)) were injected necrosis border zone NOD/SCID (non-obese diabetic/severe combined immunodeficiency) mice with left ventricular cryoinjury (CI+). Transplanted tracked by immunostaining for hNuclear antigen PCR...
A new composite membrane that consists of sulfonated poly(arylene ether sulfone) (SPES) and a highly functionalized inorganic filler sulfated zirconia (s-ZrO2) was synthesized evaluated for enhancement water retention as well proton conductivity at high temperatures above 120 °C in the absence water. Since SPES has less hydrophobic/hydrophilic difference between polymer backbone –SO3H ionic groups, channels are relatively small not easily distributed, which results no significant change...
The reinforced composite membrane with a two-layered asymmetric structure was fabricated by impregnating the Nafion on porous polyethylene (PE) substrate to reduce cost of used in proton exchange fuel cells (PEMFCs) as well enhance performance cell. ion conductivity annealed at 150 °C increases owing high crystallinity ionomer, and mechanical strength is improved strong interaction between PE ionomer. immiscibility them observed intensify interfacial resistance three-layered symmetric...
This study reports on the synthesis and characterization of an effective cathode paper electrode comprising comparatively inexpensive hydrous RuO2 (h-RuO2) nanoparticles carbon nanotubes (CNT) for anion exchange membrane (AEM) water electrolysis. The concentration CNT was varied to assess their impact electrocatalyst hydrogen evolution reaction (HER). electrocatalytic performance h-RuO2/CNT 22.0 wt% Ru evaluated. Promising results were obtained, with a current density -10 mA/cm2 at only 36...
Abstract Carbon corrosion poses a significant challenge in polymer exchange membrane fuel cells (PEMFCs), leading to reduced cell performance due catalyst layer degradation and detachment from electrodes. A promising approach address this issue involves incorporating an anticorrosive carbon material into the oxygen reduction reaction (ORR) electrode, even small quantities (≈3 wt% electrode). Herein, successful synthesis of fluorine‐doped graphene nanoribbons (F‐GNR) incorporated with...
A highly durable, anion exchange membrane with a uniform thickness of 23.4 μm was fabricated by the pore-filling approach in porous substrate. The resulting has hydroxide conductivity excess 40 mS cm−1 at 20 °C and does not exhibit significant changes ion IEC 5 M solution NaOH 50 for 1500 h.
Although previous studies have focused on risk factors for osteoarthritis, there is some debate this issue. Furthermore, associated with arthritic symptom (arthralgia) not been sufficiently investigated, despite its clinical importance in the management of osteoarthritis. This study was performed to examine osteoarthritis and contributing current pain older adults.The Fourth Korean National Health Nutrition Examination Surveys conducted 2009. Therein, 720 males 1008 females aged 65 years...
The induction of tissue-localized virus-specific CD8 T-cell response is essential for the development an effective therapeutic vaccine against genital diseases, such as cervical cancer and herpes.

Abstract Background The TeloVac study indicated GV1001 did not improve the survival of advanced pancreatic ductal adenocarcinoma (PDAC). However, cytokine examinations suggested that high serum eotaxin levels may predict responses to GV1001. This Phase III trial assessed efficacy with gemcitabine/capecitabine for eotaxin-high patients untreated PDAC. Methods Patients recruited from 16 hospitals received gemcitabine (1000 mg/m 2 , D 1, 8, and 15)/capecitabine (830 BID 21 days) per month...
Anion exchange membranes are crucial in processes involving acids and bases, yet they often suffer from proton leakage, which diminishes system efficiency membrane durability. To tackle this challenge, a novel polymeric structural approach was assessed to enhance proton-blocking performance. This scrutinized the interaction between protons proton-attracting chemical species presence or absence of dimethyl (DM) groups within poly(phenylene oxide) structure, compared with commercially...
The adsorption structure of formate species on Cu(111), prepared by two different methods, was studied using ultrahigh vacuum scanning tunneling microscopy (UHV-STM), that is, the synthesis hydrogenation CO2 at atmospheric pressure and formic acid an oxygen-precovered Cu(111). Linear chains molecules were imaged STM low coverage with distance to nearest neighbor estimated be 5.0 ± 0.2 Å, twice Cu−Cu neighbor. phase thus grows linearly initial stage anisotropic attractive interaction between...
