Productive capacity and regional value chains of the automotive sector in Southern Africa

Cogent Economics & Finance
Southern Africa is one of the major suppliers of raw materials necessary for the automotive sector’s supply chain. However, the region remains far behind in integrating into the global supply chain, with the exception of South Africa.

Implications of Nubian-Like Core Reduction Systems in Southern Africa for the Identification of Early Modern Human Dispersals

PLoS ONE, 2015
Lithic technologies have been used to trace dispersals of early human populations within and beyond Africa. Convergence in lithic systems has the potential to confound such interpretations, implying connections between unrelated groups.

Assessing the Mechanism of NH3 Sensing in Flexible Carbon‐Nanotube‐Based Chemoresistive Sensors via In Situ Photoemission Spectroscopy

Advanced Materials Interfaces, EarlyView.
Flexible carbon nanotube chemoresistors detect NH3 through charge‐transfer interactions directly revealed by in situ synchrotron X‐ray photoelectron spectroscopy. Binding‐energy shifts of ≈1 eV correlate with resistance changes, demonstrating that intra‐CNT charge transfer between NH3 and CNTs is the dominant sensing mechanism.

Host‐Directed Antiviral Activity of SB2960 Through Selective Induction and Remodeling of Stress Granules

Advanced Science, EarlyView.
Amid the ongoing threat of emerging viral pathogens, host‐directed antivirals offer a strategy to overcome viral mutation and drug resistance. SB2960, a small‐molecule inducer of stress granules (SGs), exhibits potent broad‐spectrum antiviral activity with minimal cytotoxicity.

A Modular Vaccine Platform Against SARS‐CoV‐2 Based on Self‐Assembled Protein Nanoparticles

Advanced Science, EarlyView.
A modular BP26 nanoparticle vaccine platform incorporating the SpyTag/SpyCatcher system enables high‐density, repetitive antigen display with post‐expression flexibility. Conjugation of the SARS‐CoV‐2 RBD to BP26 nanoparticles elicits strong humoral immunity and confers protection against viral challenge in vivo.
