Engineered geopolymer composites (EGCs) exhibit excellent tensile ductility and crack control ability, making them promising for concrete structure repair. However, their widespread use is limited by high costs of reinforcement fiber and a lack of an

High-strength engineered geopolymer composite (EGC) materials exhibit excellent mechanical properties under quasistatic loading, thus showing great potential in military and civilian facilities subjected to impact or explosive loading. However, its d

ABSTRACT Lsr2 is a small nucleoid-associated protein found throughout the actinobacteria. Lsr2 functions similarly to the well-studied H-NS, in that it preferentially binds AT-rich sequences and represses gene expression. In Streptomyces venezuelae,

Lsr2 is a nucleoid-associated protein conserved throughout the actinobacteria, including the antibiotic-producing Streptomyces. Streptomyces species encode paralogous Lsr2 proteins (Lsr2 and Lsr2-like, or LsrL), and we show here that of the two, Lsr2

Microbial biofilms are considerably more resistant to antibiotics than planktonic cells. It has been reported that chitosan coupling with the aminoglycoside antibiotic streptomycin dramatically disrupted biofilms of several Gram-positive bacteria. Th

Bacteria produce an impressive array of bioactive specialized metabolites, with Streptomyces (and the actinobacteria more generally) being unusually diverse and prolific producers. However, the biosynthetic potential of these organisms has yet to be

MicroRNAs (miRNAs) are critical regulators in organ development. Among them, miR-191 is known to be regulated in early embryogenesis and dysregulated in cancer. This role in undifferentiated tissues suggests a possible part of miR-191 also in bone ma

High-entropy alloys (HEAs) have been deliberated as potential matrix material for self-lubricating composites due to their excellent mechanical properties. In this study, the Al0.2Co1.5CrFeNi1.5Ti HEA powders with a face-centered cubic structure were

Bacteria and fungi are prolific producers of secondary metabolites, yet they house a multitude of silent biosynthetic gene clusters that are poorly expressed and whose products are unknown or 'cryptic'. Stimulating the expression of these clusters an
