Synthesis of Palladium Nanoparticles by Electrode-Respiring Biofilms.

Electroactive microorganisms such as can couple organic electron donor oxidation to the respiration of electrode surfaces, colonizing them in the process. These microbes can also reduce soluble metal ions, such as soluble Pd, resulting in metallic nanoparticle (NP) synthesis. Such NPs are valuable catalysts for industrially relevant chemical production; however, their chemical and solid-state syntheses are often energy-intensive and result in hazardous byproducts.

Mathematical Proficiency in Adolescents with ASD.

This study aimed to investigate the mathematical abilities of adolescents with Autism Spectrum Disorder (ASD) compared to typically developing (TD) peers, focusing on procedural thinking, arithmetic comprehension, and algebraic technique. Sixty-seven adolescents (31 with ASD, 36 TD) participated in the study. A comprehensive mathematics skills test, incorporating oral and written components, was individually administered to assess abilities across three main mathematical domains.

Language in autism: domains, profiles and co-occurring conditions.

This article reviews the current knowledge state on pragmatic and structural language abilities in autism and their potential relation to extralinguistic abilities and autistic traits. The focus is on questions regarding autism language profiles with varying degrees of (selective) impairment and with respect to potential comorbidity of autism and language impairment: Is language impairment in autism the co-occurrence of two distinct conditions (comorbidity), a consequence of autism itself (no comorbidity), or one possible combination from a series of neurodevelopmental properties (dimensional approach)? As for language profiles in autism, three main groups are identified, namely, (i) verbal autistic individuals without structural language impairment, (ii) verbal autistic individuals with structural language impairment, and (iii) minimally verbal autistic individuals. However, this tripartite distinction hides enormous linguistic heterogeneity.

Dynamic Spin-Controlled Enantioselective Catalytic Chiral Reactions.

Enantioselective catalytic chiral reactions are important to all aspects of life sciences. Here we present the first utilization of the chiral induced spin selectivity (CISS) effect to form, enantioselectively, sp chiral centers in catalytic reactions, starting from achiral reagents. The enantiomeric symmetry is broken by affecting spin-controlled different reaction dynamics toward each of the enantiomers, using magnetic substrates.
