Polymer-Supported Graphene Sheet as a Vertically Conductive Anode of Lithium-Ion Battery.

The increasing demand for electric vehicles necessitates the development of cost-effective, mass-producible, long-lasting, and highly conductive batteries. Making this kind of battery is exceedingly tricky. This study introduces an innovative fabrication technique utilizing a laser-induced graphene (LIG) approach on commercial Kapton film to create hexagonal pores.

Liquid-Metal-Assisted Synthesis of Single-Crystalline TiC Nanocubes with Exposed {100} Facets for Enhanced Electrocatalytic Activity in the Hydrogen Evolution Reaction.

Although TiC nanostructures show promise as non-noble-metal-based electrocatalysts, improved synthesis methods are required. Herein, single-crystalline TiC nanocubes with exposed {100} facets are grown by combusting TiO  + kMg + C reactive mixtures (k = 4-6.5 mol) in argon.

IgE-binding epitope analysis of Bla g 5, the German cockroach allergen.

Cockroach infestations have been linked with allergic diseases such as asthma in humans. Bla g 5, sigma class glutathione S-transferase (GST), is the major cockroach allergen which has the highest IgE response value of all cockroach allergens. Although several cockroach allergens have been identified and cloned, information regarding their B ell and T cell IgE-binding epitopes is limited.

Sequence diversity of the Bla g 4 cockroach allergen, homologous to lipocalins, from Blattella germanica.

Background: The cockroach allergen Bla g 4, a putative lipocalin, is known to exhibit frequent sequence variations. However, the previously reported cDNA sequences are truncated at the N terminus. This study was undertaken to investigate the mechanisms by which these sequence variations are generated.

Allergenicity of sigma and delta class glutathione S-transferases from the German cockroach.

Background: Cockroach glutathione S-transferases (GSTs) are known to elicit strong IgE responses. This study was undertaken to compare the IgE reactivity of German cockroach GSTs, Bla g 5 (sigma class) and delta class GST (BgGSTD1).

Methods: Full-length Bla g 5 and BgGSTD1 were cloned, and their recombinant proteins were expressed and purified.

Sequence polymorphisms of major German cockroach allergens Bla g 1, Bla g 2, Bla g 4, and Bla g 5.

Background: The allergenicity of allergens could be influenced by amino acid substitutions in B- or T-cell epitope regions. The German cockroach is known to produce potent allergens inducing strong IgE-mediated allergic reactions. This study was performed to investigate sequence variations in major allergens of the German cockroach.
