Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

open access: yesAdvanced Functional Materials, EarlyView.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3

open access: yesAdvanced Functional Materials, EarlyView.
Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.

Firm Age and Performance [PDF]

open access: possibleSSRN Electronic Journal, 2009
As firms grow older, their profitability seems to decline. We first document this phenomenon and show that it is very robust. Then we offer two non-exclusive explanations of why firms may age. First, corporate aging could reflect a cementation of organizational rigidities over time.

Unions, Training, and Firm Performance [PDF]

open access: possibleSSRN Electronic Journal, 2008
This paper uses data from two British workplace surveys to examine the impact of unions on several training measures. It also evaluates the impact of unions and training on earnings and two measures of firm performance. Union effects on training emerge as fairly subtle, and are more positive when using individual rather than plant-wide training data. A

Firm‐wide integration and firm performance

The International Journal of Logistics Management, 2007
PurposeThis paper is intended to extend previous research by exploring the scope of integration and its impact on firm performance. In addition to, examining dyadic integrative relationships, the research also looks at firm‐wide process‐oriented integration.Design/methodology/approachLiterature on collaboration and integration was reviewed along with ...

Employee Health and Firm Performance

SSRN Electronic Journal, 2022
When workers are in bad health, their productivity declines. We investigate whether the health of employees affects firm performance, taking advantage of the severity of the seasonal influenza seasons as a source of exogenous variation. We find that firms whose employees are particularly affected by influenza experience reductions in their return on ...
