Bond Formation: Shaken, Not Stirred

open access: yesChemistry – A European Journal, EarlyView.
Shaking of seismo‐molecules efficiently transforms kinetic energy into storable chemical potential, unlocking high‐utility Gibbs free energy. This innovative mechanism pioneers uncharted scientific frontiers, introducing fascinating phenomena like seismochemistry, seismochromism, and seismofluorescence that redefine the boundaries of molecular ...

COMPARATIVE ANALYSIS AND EVALUATION OF THE CONVERSION FORMULA FOR REBOUND NUMBER OF SCHMIDT HAMMER TEST AND UNCONFINED COMPRESSIVE STRENGTH TEST – CASE STUDY: ANDESITE ROCK SLOPE IN GRAHA PUSPA, LEMBANG FAULT

open access: yesRudarsko-geološko-naftni Zbornik
The Unconfined Compressive Strength (UCS) test is one of the most common methods for determining the rock material strength value. However, the size and complexity of the instrument do not allow UCS testing to be carried out in the field.

Age Factor on Estimating of Strength of Concrete in Structures by Rebound Hammer

open access: yesConcrete Research and Technology, 2012
The relationship between the rebound number and strength of concrete varies as a function of the age of concrete, but the effect of age can generally be ignored for concrete between 3 days and 3 months old. However, for older concrete, it may be possible to develop the age factor of the rebound number of concrete taking into account the concrete's ...

Breadth at the Helm: Generalist CEOs and Corporate ESG Performance‐Evidence From China

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Drawing on the Upper Echelons Theory and the Imprinting Theory, this study conjectures that generalist CEOs may have a stronger tendency to pursue environmental, social and governance (ESG) goals. We perform multiple regression analyses with observations of Shanghai and Shenzhen A‐share listed companies from 2010 to 2023 in order to explore ...
